Next, the worker heats the first mold 110 and the second mold 130 as the fourth step. Specifically, the worker operates the operation panel 161 to instruct the control device 160 to energize the first mold 110 and the second mold 130. In response to this instruction, the control device 160 controls the operation of the power supply device 153 and starts energizing the first conductor plate 120 and the second conductor plate 140 via the input / output electrodes 150a and 150b. Thus, the current output from the power feeding device 153 is supplied to the first conductor plate 120 (or the second conductor plate 140) via the input / output electrode 150a (or the input / output electrode 150b), and then the current-carrying connection body 151 is supplied. Through the second conductor plate 140 (or the first conductor plate 120) and return to the power feeding device 153 through the input / output electrode 150b (or the input / output electrode 150a).
これにより、第1金型110および第2金型130は、第1導体板120および第2導体板140に流れる高周波電流によって電磁誘導現象が生じて誘導加熱される。この場合、第1導体板120および第2導体板140は、それぞれ第1成型部111および第2成型部131を覆う大きさに形成されているため、第1成型部111および第2成型部131の各全面が加熱される。また、この場合、本発明者の実験によれば、第1金型110および第2金型130に直接交流電流を流した通電加熱した場合に比べて誘電加熱の方が2割~3割程度短い時間で目標温度に達することができることを確認した。
Thus, the first mold 110 and the second mold 130 are induction-heated by an electromagnetic induction phenomenon caused by the high-frequency current flowing through the first conductor plate 120 and the second conductor plate 140. In this case, since the first conductor plate 120 and the second conductor plate 140 are formed to have a size covering the first molding part 111 and the second molding part 131, respectively, the first molding part 111 and the second molding part 131 are formed. Each whole surface of is heated. Further, in this case, according to the experiments of the present inventors, the dielectric heating is about 20% to 30% compared to the case where the first mold 110 and the second mold 130 are directly heated by supplying an alternating current. It was confirmed that the target temperature could be reached in a short time.
次に、作業者は、第1成型部111および第2成型部131がそれぞれ目標温度(例えば、500℃)に達して予熱が完了した場合には、第5工程として製品PRの成型加工を行う。具体的には、作業者は、操作パネル161を操作して制御装置160に対して第1導体板120および第2導体板140への給電を停止させるとともにキャビティ132内への被成型材料MTの供給を指示する。
Next, when the first molding unit 111 and the second molding unit 131 each reach a target temperature (for example, 500 ° C.) and the preheating is completed, the worker performs the molding process of the product PR as the fifth process. . Specifically, the operator operates the operation panel 161 to stop the power supply to the first conductor plate 120 and the second conductor plate 140 with respect to the control device 160, and the molding material MT into the cavity 132. Direct supply.
この指示に応答して、制御装置160は、給電装置153の作動を制御して第1導体板120および第2導体板140への給電を停止させるとともに、ガス供給装置126の作動を制御して坩堝124内に気体を導入して内部圧力を上昇させる(図3において破線矢印参照)。これにより、坩堝124内の溶湯状態の被成型材料MTは、容器本体124a内の圧力上昇に伴って導入管112を介してキャビティ132内に導かれるとともに、第1金型110および第2金型130の温度低下に応じてキャビティ132内で固化して成型される。この場合、キャビティ132内に導かれる溶湯状態の被成型材料MTは、第1成型部111および第2成型部131がそれぞれ予熱されているため、キャビティ132の奥部に行き渡るまでの間に著しく粘度が低下したり固化したりすることがないため、精度良く製品PRを成型することができる。
In response to this instruction, the control device 160 controls the operation of the power supply device 153 to stop the power supply to the first conductor plate 120 and the second conductor plate 140 and also controls the operation of the gas supply device 126. Gas is introduced into the crucible 124 to increase the internal pressure (see broken line arrows in FIG. 3). As a result, the material to be molded MT in the molten state in the crucible 124 is guided into the cavity 132 through the introduction pipe 112 as the pressure in the container body 124a rises, and the first mold 110 and the second mold In accordance with the temperature drop of 130, it is solidified and molded in the cavity 132. In this case, since the first molding part 111 and the second molding part 131 are preheated respectively, the molten material to be molded MT guided into the cavity 132 has a remarkably high viscosity before reaching the inner part of the cavity 132. The product PR can be molded with high accuracy because it does not decrease or solidify.
また、この被成型材料MTのキャビティ132内への導入の前、導入後、または固化過程中において、作業者は、操作パネル161を介して制御装置160に指示することにより、電極配置装置152の作動を制御して入出力電極150a,150bおよび通電接続体151を第1導体板120および第2導体板140からそれぞれ離隔させることができる。なお、第1導体板120および第2導体板140への給電停止は、キャビティ132内に被成型材料MTを導入した後であってもよい。
In addition, before the introduction of the molding material MT into the cavity 132, after the introduction, or during the solidification process, the operator instructs the control device 160 via the operation panel 161 to By controlling the operation, the input / output electrodes 150a and 150b and the energized connection body 151 can be separated from the first conductor plate 120 and the second conductor plate 140, respectively. The power supply to the first conductor plate 120 and the second conductor plate 140 may be stopped after the material to be molded MT is introduced into the cavity 132.
次に、作業者は、第6工程として、製品PRの取り出し作業を行う。具体的には、作業者は、操作パネル161を操作して制御装置160に対して第2金型130の上昇を指示する。この指示に応答して制御装置160は、金型駆動装置144の作動を制御して第2金型130を第1金型110から離隔させて金型を開く。この場合、制御装置160は、第2金型130に設けられた図示しないエジェクタピンを駆動させることにより第2金型130の第2成型部131内に位置する製品PRを押し出させる。これにより、作業者は、製品PRを得ることができるとともに、この製品PRに対して必要な後加工を施して製品PRを完成させることができる。
Next, the worker performs the work of taking out the product PR as the sixth step. Specifically, the operator operates the operation panel 161 to instruct the controller 160 to raise the second mold 130. In response to this instruction, the control device 160 controls the operation of the mold driving device 144 to separate the second mold 130 from the first mold 110 and open the mold. In this case, the control device 160 drives the ejector pin (not shown) provided in the second mold 130 to push out the product PR located in the second molding part 131 of the second mold 130. As a result, the operator can obtain the product PR, and can perform necessary post-processing on the product PR to complete the product PR.
次いで、作業者は、製品PRの製造を続けて行なう場合には、再度、前記第2工程または前記第3工程から作業を開始する。一方、製品PRの製造を終了する場合には、作業者は、操作パネル161を操作して成型装置100の電源をOFFにする。これにより、作業者は、成型装置100による製品PRの製造作業を終了することができる。
Next, when the worker continues to manufacture the product PR, the worker starts the work again from the second step or the third step. On the other hand, when the manufacture of the product PR is finished, the operator operates the operation panel 161 to turn off the power of the molding apparatus 100. Thereby, the operator can finish the manufacturing operation of the product PR by the molding apparatus 100.

Since each of the tools 135 is provided, it is not necessary to provide the first electrode 110 and the second mold 130 with the current-carrying electrodes according to the conventional technique. As a result, in the molding apparatus 100 according to the present invention, the first mold 110 and the second mold 130 can be easily manufactured, and the non-energized molds can be used as they are. Can be used as In this case, as a non-energized mold, in addition to the mold in which the conventional electrode is not provided, the conductive electrode may be provided for some reason such as the size of the empty space or the relationship with the first molding part.

Furthermore, since the molding apparatus 200 is formed in such a size that the first conductor plate 120 and the second conductor plate 140 cover the wrinkle presser 116 and the wrinkle presser receiver 136, the wrinkle presser 116 and the wrinkle presser receiver 136 are also guided.

この指示に応答して、制御装置160は、給電装置153の作動を制御して第1導体板120および第2導体板140への給電を停止させるとともに、金型駆動装置144の作動を制御して第2金型130を第1金型110に対して押し付ける(図7参照)。これにより、キャビティ132内の熱せられた被成型材料MTは第1成型部111、第2成型部131によって成型される。この場合、成型装置200は、第1成型部111、第2成型部131、シワ押さえ116およびシワ押さえ受け136が被成型材料MTと同じまたは近い温度に熱せられているため、精度の良いプレス加工を行うことができる。
In response to this instruction, the control device 160 controls the operation of the power feeding device 153 to stop the power feeding to the first conductor plate 120 and the second conductor plate 140 and also controls the operation of the mold driving device 144. Then, the second mold 130 is pressed against the first mold 110 (see FIG. 7). Thus, the heated molding material MT in the cavity 132 is molded by the first molding unit 111 and the second molding unit 131. In this case, in the molding apparatus 200, the first molding unit 111, the second molding unit 131, the wrinkle presser 116, and the wrinkle presser receiver 136 are heated to the same or close temperature as the molding material MT.

Note that the operator controls the operation of the electrode placement device 152 by instructing the control device 160 via the operation panel 161 before and after the press working of the molding material MT, so that the input / output electrodes 150a and 150b and The energizing connection body 151 can be separated from the first conductor plate 120 and the second conductor plate 140. In the above description of the operation, energization of the first conductor plate 120 and the second conductor plate 140 is stopped in the press working of the molding material MT, but an alternating current is applied to the first conductor plate 120 and the second conductor plate 140. The material to be molded MT can also be pressed in a state where the material is flowed, that is, in a state where the first molding part 111, the second molding part 131, the material MT to be molded, and the like are heated. In particular, in plastic processing of a material having poor extensibility such as a magnesium material, accurate plastic processing can be performed by processing while maintaining a heated state.
次に、作業者は、第6工程として、上記第1実施形態と同様にして製品PRの取り出し作業を行う。これにより、作業者は、製品PRを得ることができるとともに、この製品PRに対して必要な後加工を施して製品PRを完成させることができる。次いで、作業者は、製品PRの製造を続けて行なう場合には、再度、前記第2工程から作業を開始する。一方、製品PRの製造を終了する場合には、作業者は、操作パネル161を操作して成型装置100の電源をOFFにする。これにより、作業者は、成型装置200による製品PRの製造作業を終了することができる。
Next, the worker performs the work of taking out the product PR as in the first embodiment as the sixth step. As a result, the operator can obtain the product PR, and can perform necessary post-processing on the product PR to complete the product PR. Next, when the worker continues to manufacture the product PR, the worker starts again from the second step. On the other hand, when the manufacture of the product PR is finished, the operator operates the operation panel 161 to turn off the power of the molding apparatus 100. As a result, the worker can finish the production work of the product PR by the molding apparatus 200.

As a result, the molding apparatus 200 includes the first molding unit 111 and the second molding unit 131 that are induction-heated in the same manner as in the first embodiment, in addition to the first and second embodiments. The material to be molded MT disposed between the molding part 111 and the second molding part 131 is also induction-heated. The material to be molded MT is also heated by heat transfer from the first molding part 111, the first outer peripheral part 110a, the second molding part 131, and the second outer peripheral part 130a.
次に、作業者は、被成型材料MTの予熱に適した目標温度(例えば、被成型材料MTの融点未満である200℃)に達した場合には、第5工程として製品PRの成型加工を行う。具体的には、作業者は、操作パネル161を操作して制御装置160に対して被成型材料MTの加工の開始を指示する。
Next, when the worker reaches a target temperature suitable for preheating the molding material MT (for example, 200 ° C. which is lower than the melting point of the molding material MT), the worker performs molding processing of the product PR as the fifth step. Do. Specifically, the operator operates the operation panel 161 and instructs the control device 160 to start processing the molding material MT.
この指示に応答して、制御装置160は、第1導体板120および第2導体板140に通電した状態で金型駆動装置144の作動を制御して第2金型130を第1金型110に対して押し付けるとともに、バキューム装置171の作動を制御して型締めされた第1金型110と第2金型130との間のキャビティ132内の空気の吸引を開始する。

The suction of the air in the cavity 132 between the first mold 110 and the second mold 130 clamped by controlling the operation of the vacuum device 171 is started.
そして、制御装置160は、給電装置153の作動を制御して第1成型部111および第2成型部131の温度を被成型材料MTの熱可塑性樹脂シートが溶融する温度まで加熱するとともに同温度状態を所定時間維持する(図10参照)。本実施形態においては、制御装置160は、第1成型部111および第2成型部131の温度を概ね250℃~300℃の温度に加熱して同温度に維持する。これにより、第1成型部111と第2成型部131との間に配置されている被成型材料MTの2つの熱可塑性樹脂シートが溶融して繊維シート内にそれぞれ含浸する(図10参照)。
Then, the control device 160 controls the operation of the power feeding device 153 to heat the temperatures of the first molding part 111 and the second molding part 131 to a temperature at which the thermoplastic resin sheet of the molding material MT is melted and at the same temperature state.

In the present embodiment, the control device 160 heats the temperature of the first molding part 111 and the second molding part 131 to a temperature of approximately 250 ° C. to 300 ° C. and maintains the same temperature. Thereby, the two thermoplastic resin sheets of the molding material MT arranged between the first molding part 111 and the second molding part 131 are melted and impregnated in the fiber sheet, respectively (see FIG. 10).
次に、作業者は、被成型材料MTにおける熱可塑性樹脂シートが繊維シートに含浸するに必要な時間の経過後、操作パネル161を操作することにより制御装置160に対して冷却処理を指示する。この指示に応答して、制御装置160は、給電装置153の作動を制御して第1金型110および第2金型130に対する通電を停止するとともに、給水ポンプ170の作動を制御することにより第1空洞部118および第2空洞部138内にそれぞれ冷却水を導入する(図10における破線矢印参照)。これにより、第1成型部111、第1外周部110a、第2成型部131および第2外周部130aが急速に冷却されるとともに被成型材料MTが急速に冷却されて製品PRが成型される。
Next, the operator instructs the control device 160 to perform a cooling process by operating the operation panel 161 after the time necessary for the thermoplastic resin sheet in the molding material MT to impregnate the fiber sheet. In response to this instruction, the control device 160 controls the operation of the power supply device 153 to stop energization of the first mold 110 and the second mold 130 and controls the operation of the water supply pump 170 to control the first operation. Cooling water is introduced into each of the first cavity portion 118 and the second cavity portion 138 (see broken line arrows in FIG. 10). Thereby, the first molding part 111, the first outer peripheral part 110a, the second molding part 131, and the second outer peripheral part 130a are rapidly cooled, and the material MT is rapidly cooled to mold the product PR.

Next, the molding process of the product PR using the
次に、作業者は、第2工程として、第1金型110および第2金型130をそれぞれ予備加熱する。具体的には、作業者は、図11に示すように、操作パネル161を操作して金型駆動装置144の作動を制御することにより第2金型130を第1金型110に押し付けて型締めした後、操作パネル161を操作して電極配置装置152の作動を制御することにより入出力電極150a,150bおよび通電接続体151を第1導体板120および第2導体板140にそれぞれ接近させて電極接触部121,141にそれぞれ接触させる。
Next, the worker preheats the first mold 110 and the second mold 130 as the second step. Specifically, as shown in FIG. 11, the operator presses the second mold 130 against the first mold 110 by operating the operation panel 161 and controlling the operation of the mold driving device 144 to mold the mold. After tightening, the operation panel 161 is operated to control the operation of the electrode placement device 152 so that the input / output electrodes 150a and 150b and the energized connection body 151 are brought close to the first conductor plate 120 and the second conductor plate 140, respectively. The electrode contact portions 121 and 141 are brought into contact with each other.
次いで、作業者は、操作パネル161を操作して給電装置153の作動を制御することにより第1導体板120と第2導体板140との間に交流電流を流す。これにより、成型装置300は、上記第1~3実施形態と同様にして第1成型部111および第2成型部131がそれぞれ誘導加熱される。なお、この金型の予備加熱工程においては、第1金型110と第2金型130とを離隔させた状態で通電を行ってもよい。
Next, the operator operates the operation panel 161 to control the operation of the power feeding device 153, thereby causing an alternating current to flow between the first conductor plate 120 and the second conductor plate 140. Thereby, in the molding apparatus 300, the first molding part 111 and the second molding part 131 are induction-heated in the same manner as in the first to third embodiments. In the mold preheating step, the first mold 110 and the second mold 130 may be energized while being separated from each other.

Next, as shown in FIG. 13, the worker arranges the bag-shaped molding material MT including the filling bag B on the first molding part 111 of the first mold 110. In this case, the filling bag B is a bag body that is inflated by the air supplied by the filling tube 180, and is formed of a sheet-like heat-resistant material (for example, a silicon rubber sheet). The material to be molded MT is configured by wrapping the filling bag B with a so-called prepreg in which a thermoplastic resin is impregnated in advance with a laminated sheet body or a fiber sheet in which a thermoplastic resin sheet and a fiber sheet are laminated. In this case, the molding material MT can be disposed so as to cover the upper surface and the lower surface of the filling bag B without completely surrounding the filling bag B.
次に、作業者は、第4工程として製品PRの成型加工を行う。具体的には、作業者は、操作パネル161を操作して制御装置160に対して被成型材料MTの加工の開始を指示する。この指示に応答して、制御装置160は、金型駆動装置144の作動を制御して第2金型130を第1金型110に対して押し付けるとともに、バキューム装置171の作動を制御して型締めされた第1金型110と第2金型130との間のキャビティ132内の空気の吸引を開始する。次いで、制御装置160は、管駆動装置182の作動を制御して充填管180を前進させることにより先端部を充填袋B内に位置させた後、充填材供給装置181の作動を制御して圧縮空気の供給を開始する(図14において破線矢印参照)。この場合、充填管180は、先端部が尖って形成されているため、被成型材料MTおよび充填袋Bを突き破って充填袋B内に進入する。
Next, the worker performs the molding process of the product PR as the fourth step. Specifically, the operator operates the operation panel 161 and instructs the control device 160 to start processing the molding material MT. In response to this instruction, the control device 160 controls the operation of the mold driving device 144 to press the second mold 130 against the first mold 110 and controls the operation of the vacuum device 171 to control the mold. The suction of the air in the cavity 132 between the clamped first mold 110 and the second mold 130 is started. Next, the control device 160 controls the operation of the filling material supply device 181 after controlling the operation of the tube driving device 182 to move the filling tube 180 forward so that the tip portion is positioned in the filling bag B. The supply of air is started (see broken line arrow in FIG. 14). In this case, since the filling tube 180 is formed with a sharp tip, the filling tube 180 breaks through the molding material MT and the filling bag B and enters the filling bag B.
これにより、図14に示すように、キャビティ132内の被成型材料MTは、充填袋Bの膨張によって第1成型部111および第2成型部131の表面に押し付けられて成型される。この場合、成型装置400は、予備加熱された第1金型110および第2金型130によって被成型材料MTにおける熱可塑性樹脂を溶融させて成型してもよいし、第1導体板120および第2導体板140に通電を行って第1金型110および第2金型130を加熱して被成型材料MTにおける熱可塑性樹脂を溶融させて成型してもよい。
Thereby, as shown in FIG. 14, the molding material MT in the cavity 132 is pressed and molded against the surfaces of the first molding part 111 and the second molding part 131 by the expansion of the filling bag B. In this case, the molding apparatus 400 may perform molding by melting the thermoplastic resin in the molding material MT with the preheated first mold 110 and the second mold 130, or the first conductor plate 120 and the first mold 120. The two-conductor plate 140 may be energized to heat the first mold 110 and the second mold 130 to melt the thermoplastic resin in the material MT to be molded.
次に、作業者は、被成型材料MTの成型に必要な時間の経過後、操作パネル161を操作することにより制御装置160に対して冷却処理を指示する。この指示に応答して、制御装置160は、給電装置153の作動を制御して第1金型110および第2金型130に対する通電、充填袋B内への圧縮空気の供給をそれぞれ停止するとともに、給水ポンプ170の作動を制御することにより第1空洞部118および第2空洞部138内にそれぞれ冷却水を導入する(図14における破線矢印参照)。これにより、第1成型部111、第1外周部110a、第2成型部131および第2外周部130aが急速に冷却されるとともに被成型材料MTが急速に冷却されて製品PRが成型される。
Next, the operator instructs the control device 160 to perform a cooling process by operating the operation panel 161 after the time necessary for molding the molding material MT has elapsed. In response to this instruction, the control device 160 controls the operation of the power supply device 153 to stop energization of the first mold 110 and the second mold 130 and supply of compressed air into the filling bag B, respectively. Then, by controlling the operation of the water supply pump 170, cooling water is introduced into the first cavity 118 and the second cavity 138, respectively (see broken line arrows in FIG. 14). Thereby, the first molding part 111, the first outer peripheral part 110a, the second molding part 131, and the second outer peripheral part 130a are rapidly cooled, and the material MT is rapidly cooled to mold the product PR.
次に、作業者は、第5工程として、上記各第1~3実施形態と同様にして製品PRの取り出し作業を行う。これにより、作業者は、製品PRを得ることができるとともに、この製品PRに対して必要な後加工を施して製品PRを完成させることができる。次いで、作業者は、製品PRの製造を続けて行なう場合には、再度、前記第2工程から作業を開始する。一方、製品PRの製造を終了する場合には、作業者は、操作パネル161を操作して成型装置100の電源をOFFにする。これにより、作業者は、成型装置400による製品PRの製造作業を終了することができる。
Next, as a fifth step, the worker performs the work of taking out the product PR as in the first to third embodiments. As a result, the operator can obtain the product PR, and can perform necessary post-processing on the product PR to complete the product PR. Next, when the worker continues to manufacture the product PR, the worker starts again from the second step. On the other hand, when the manufacture of the product PR is finished, the operator operates the operation panel 161 to turn off the power of the molding apparatus 100. Thereby, the operator can finish the production work of the product PR by the molding apparatus 400.
さらに、本発明の実施にあたっては、上記各第1~4実施形態に限定されるものではなく、本発明の目的を逸脱しない限りにおいて種々の変更が可能である。なお、下記各変形例を示す図16~図18においては、上記各実施形態における成型装置100の構成部分に対応する部分に同じ符号を付して、これらの説明は適宜省略する。なお、以下に述べる各変形例は、成型装置100,200,300,400の相互間でも同様に実施することができる。
Furthermore, the implementation of the present invention is not limited to the first to fourth embodiments described above, and various modifications can be made without departing from the object of the present invention. In FIGS. 16 to 18 showing the following modifications, the same reference numerals are given to portions corresponding to the constituent portions of the molding apparatus 100 in each of the above embodiments, and description thereof will be omitted as appropriate. In addition, each modification described below can be similarly implemented between the molding apparatuses 100, 200, 300, and 400.
例えば、上記各実施形態においては、成型装置100,200,300,400は、第1導体板120および第2導体板140をそれぞれ備えて構成した。しかし、成型装置100,200,300は、第1導体板120および第2導体板140のうちの少なくとも一方を備えて構成されていればよい。
For example, in each of the above embodiments, the molding apparatuses 100, 200, 300, and 400 are configured to include the first conductor plate 120 and the second conductor plate 140, respectively. However, the molding apparatuses 100, 200, and 300 may be configured to include at least one of the first conductor plate 120 and the second conductor plate 140.
例えば、図16には、第2導体板140を省略した成型装置100を示している。この場合、成型装置100は、第1導体板120の第1成型部111を介した両端に入出力電極150a,150bを接続することにより、第1導体板120にのみ交流電流を流すことができる。また、成型装置100は、図16に示すように、第1導体板120と第2金型130とを通電接続体151を介して電気的に接続するとともに、これらの第1導体板120および第2金型130に入出力電極150a,150bをそれぞれ接続することによって第1導体板120と第2金型130との間に交流電流を流すこともできる。なお、図11においては、第2金型130を第2プラテン143に取り付けるための取付部133および第2金型取付具135を省略して示している。また、絶縁体142は、第2金型130と第2プラテン143間を絶縁している。
For example, FIG. 16 shows the molding apparatus 100 in which the second conductor plate 140 is omitted. In this case, the molding apparatus 100 can cause an alternating current to flow only through the first conductor plate 120 by connecting the input / output electrodes 150a and 150b to both ends of the first conductor plate 120 via the first molding portion 111. . As shown in FIG. 16, the molding apparatus 100 electrically connects the first conductor plate 120 and the second mold 130 via the energizing connection body 151, and the first conductor plate 120 and the second mold 130. By connecting the input / output electrodes 150 a and 150 b to the two molds 130, an alternating current can be passed between the first conductive plate 120 and the second mold 130. In FIG. 11, the attachment part 133 and the second mold attachment tool 135 for attaching the second mold 130 to the second platen 143 are omitted. The insulator 142 insulates between the second mold 130 and the second platen 143.
また、上記各実施形態においては、第1金型取付具115および第2金型取付具135をネジ付きストラップクランプで構成した。しかし、第1金型取付具115および第2金型取付具135は、第1プラテン123および第2プラテン143にそれぞれ第1金型110および第2金型130を着脱自在に取り付けることができればよい。すなわち、第1金型取付具115および第2金型取付具135が、本発明に係る第1金型取付手段および第2金型取付手段に相当する。したがって、第1金型取付手段および第2金型取付手段は、ネジ付きストラップクランプ以外のもの、例えば、ステップストラップ、チャック、バイス、取付ボルトまたは磁気クランプ(磁力のオンオフで磁性体を着脱自在に保持する器具)などを採用することができる。
In each of the above embodiments, the first mold fixture 115 and the second mold fixture 135 are configured with threaded strap clamps. However, the first mold fixture 115 and the second mold fixture 135 are only required to detachably attach the first mold 110 and the second mold 130 to the first platen 123 and the second platen 143, respectively. . That is, the first mold mounting tool 115 and the second mold mounting tool 135 correspond to the first mold mounting means and the second mold mounting means according to the present invention. Therefore, the first mold mounting means and the second mold mounting means may be other than a threaded strap clamp, for example, a step strap, chuck, vise, mounting bolt or magnetic clamp (a magnetic body can be attached or detached with magnetic on / off). A holding instrument) can be employed.
また、第1金型取付手段および第2金型取付手段は、上記各実施形態のように、第1金型110および第2金型130を第1導体板120および第2導体板140に取り付けるものであってよいが、第1金型110および第2金型130を第1導体板120および第2導体板140とともに第1プラテン123および第2プラテン143に取り付けるものであってもよい。これによれば、第1導体板120および第2導体板140の厚さを薄く形成できるとともに大きさも小さく構成することができる。なお、第1金型110および第2金型130を第1導体板120、第2導体板140、第1プラテン123および第2プラテン143に対して電気的に絶縁する場合には、第1金型取付手段および第2金型取付手段を絶縁体や絶縁体で被覆して構成することは当然である。
The first mold attaching means and the second mold attaching means attach the first mold 110 and the second mold 130 to the first conductor plate 120 and the second conductor plate 140 as in the above embodiments. However, the first mold 110 and the second mold 130 may be attached to the first platen 123 and the second platen 143 together with the first conductor plate 120 and the second conductor plate 140. According to this, the thickness of the first conductor plate 120 and the second conductor plate 140 can be reduced and the size can be reduced. When the first mold 110 and the second mold 130 are electrically insulated from the first conductor plate 120, the second conductor plate 140, the first platen 123, and the second platen 143, the first mold Of course, the mold attaching means and the second mold attaching means are configured by covering with an insulator or an insulator.
また、上記各実施形態においては、第1金型110および第2金型130を絶縁体114,134を介して第1導体板120および第2導体板140に取り付けることにより第1金型110および第2金型130と第1導体板120および第2導体板140とを互いに電気的に絶縁した状態で取り付けた。しかし、成型装置100は、絶縁体114,134のうちの一方を省略して第1金型110および第2金型130のうちの一方と第1導体板120および第2導体板140のうちの一方とを互いに電気的に接続して構成することもできるとともに、例えば、図17に示すように、絶縁体114,134をそれぞれ省略して第1金型110および第2金型130と第1導体板120および第2導体板140とを互いに電気的に接続して構成することもできる。
In each of the above embodiments, the first mold 110 and the second mold 130 are attached to the first conductor plate 120 and the second conductor plate 140 via the insulators 114 and 134, so that the first mold 110 and The second mold 130, the first conductor plate 120, and the second conductor plate 140 were attached in a state where they were electrically insulated from each other. However, in the molding apparatus 100, one of the insulators 114 and 134 is omitted, and one of the first mold 110 and the second mold 130 and the first conductor plate 120 and the second conductor plate 140 are omitted. For example, as shown in FIG. 17, the insulators 114 and 134 may be omitted, and the first mold 110 and the second mold 130 may be connected to the first mold. The conductor plate 120 and the second conductor plate 140 may be configured to be electrically connected to each other.
また、上記各実施形態においては、成型装置100,200,300,400は、1つの給電装置153に対して一組の第1金型110および第2金型130を接続するように構成した。しかし、成型装置100,200,300,400は、1つの給電装置153に対して複数組の第1金型110および第2金型130を接続してこれらに対して同時にまたは選択的に交流電流を流して成型加工を行うように構成することもできる。
In each of the above embodiments, the molding apparatuses 100, 200, 300, and 400 are configured to connect a pair of the first mold 110 and the second mold 130 to one power supply apparatus 153. However, in the molding apparatuses 100, 200, 300, and 400, a plurality of sets of the first mold 110 and the second mold 130 are connected to one power supply apparatus 153, and alternating current is selectively or selectively applied to these. It is also possible to configure so as to carry out molding processing.
また、上記各実施形態においては、成型装置100,200,300,400は、電極配置装置152を備えることにより入出力電極150a,150bおよび通電接続体151を第1導体板120および第2導体板140に対して接続および離隔するように構成した。しかし、成型装置100,200,300,400は、可動側の第2金型130の変位に応じてこの第2金型130に接続される入出力電極150bおよび通電接続体151を可動可能に構成すれば電極配置装置152を省略して入出力電極150a,150bおよび通電接続体151を第1金型110および第2金型130に固定的に接続して構成することもできる。
In each of the above embodiments, the molding devices 100, 200, 300, and 400 include the electrode arrangement device 152, so that the input / output electrodes 150 a and 150 b and the energizing connection body 151 are connected to the first conductor plate 120 and the second conductor plate. 140 was configured to be connected to and separated from 140. However, the molding apparatus 100, 200, 300, 400 is configured such that the input / output electrode 150 b and the current-carrying connection body 151 connected to the second mold 130 can be moved according to the displacement of the second mold 130 on the movable side. In this case, the electrode arrangement device 152 may be omitted, and the input / output electrodes 150a and 150b and the energizing connection body 151 may be fixedly connected to the first mold 110 and the second mold 130.
また、入出力電極150a,150bは、通電接続体151と同様に、第1導体板120と第2導体板140によって挟まれるように構成することができる。具体的には、入出力電極154は、例えば、図18に示すように、入出力電極150aと入出力電極150bとの間に絶縁体からなる連結絶縁体150cを設けて一体的に構成することができる。そして、この場合、成型装置200は、第2導体板140の外縁部から第1導体板120側に向かって延びる板状の導体からなる2つの延設電極155a,155bをそれぞれ設ける。この場合、延設電極155aの長さは、第1金型110と第2金型130とが閉じた状態における電極接触部121と電極接触部141との間の距離から入出力電極154の厚さを減じた長さに形成される。また、延設電極155bの長さは、第1金型110と第2金型130とが閉じた状態における電極接触部121と電極接触部141との間の距離から通電接続体151の厚さを減じた長さに形成される。
Also, the input / output electrodes 150 a and 150 b can be configured to be sandwiched between the first conductor plate 120 and the second conductor plate 140, similarly to the energized connection body 151. Specifically, for example, as shown in FIG. 18, the input / output electrode 154 is integrally configured by providing a connecting insulator 150c made of an insulator between the input / output electrode 150a and the input / output electrode 150b. Can do. In this case, the molding apparatus 200 is provided with two extended electrodes 155a and 155b each made of a plate-like conductor extending from the outer edge of the second conductor plate 140 toward the first conductor plate 120 side. In this case, the length of the extended electrode 155a is determined based on the distance between the electrode contact part 121 and the electrode contact part 141 in a state where the first mold 110 and the second mold 130 are closed. The length is reduced. Further, the length of the extended electrode 155b is determined based on the distance between the electrode contact portion 121 and the electrode contact portion 141 when the first mold 110 and the second mold 130 are closed. It is formed to a length reduced.
このように構成した成型装置200によれば、第1金型110と第2金型130とが閉じた際に、入出力電極154および通電接続体151は、延設電極155a,155bを介して第1導体板120と第2導体板140とで挟まれるため、第1導体板120および第2導体板140に対してより精度良く安定的に通電を行うことができる。なお、延設電極155a,155bは、どちらか一方が第1金型110または第2金型130に電気的に接続されていれもよいことは当然である。また、入出力電極154および延設電極155a,155bは、成型装置100,300,400に適用できることは当然である。
According to the molding apparatus 200 configured as described above, when the first mold 110 and the second mold 130 are closed, the input / output electrode 154 and the energized connection body 151 are connected via the extended electrodes 155a and 155b. Since it is sandwiched between the first conductor plate 120 and the second conductor plate 140, the first conductor plate 120 and the second conductor plate 140 can be energized more accurately and stably. Of course, either one of the extended electrodes 155 a and 155 b may be electrically connected to the first mold 110 or the second mold 130. Of course, the input / output electrode 154 and the extended electrodes 155a and 155b can be applied to the molding apparatuses 100, 300, and 400.
また、上記各実施形態においては、成型装置100,200,300,400は、第1金型110および第2金型130の各側面に溝状の取付部113,133を形成した。しかし、取付部113,133は、第1金型取付具115および第2金型取付具135が掛けられる形状であればよく、溝状以外の形状、例えば、第1金型110および第2金型130の各側面からフランジ状または片状に張り出して形成されていてもよい。なお、この取付部113,133は、本発明の成型装置のために新たに設けられるものであってもよいが、従来の金型であれば第1プラテン123および第2プラテン143にそれぞれ取り付けるために予め設けられているものであり、これらの既存の取付部を取付部113,133として用いることができる。
In each of the embodiments described above, the molding apparatuses 100, 200, 300, and 400 formed the groove-shaped attachment portions 113 and 133 on the side surfaces of the first mold 110 and the second mold 130. However, the attachment portions 113 and 133 may have any shape as long as the first mold attachment 115 and the second mold attachment 135 can be hung, and may have shapes other than the groove shape, for example, the first mold 110 and the second mold. It may be formed by projecting from each side of the mold 130 in a flange shape or a piece shape. The attachment portions 113 and 133 may be newly provided for the molding apparatus of the present invention. However, in the case of a conventional mold, the attachment portions 113 and 133 are attached to the first platen 123 and the second platen 143, respectively. These existing mounting portions can be used as the mounting portions 113 and 133.

It is also possible to configure so as to exhibit the electrical insulation function.
また、上記第3,4実施形態においては、被成型材料MTを熱可塑性樹脂シートと繊維シートとで構成した。しかし、被成型材料MTは、製品PRの仕様に応じて適宜選定されるものである。したがって、被成型材料MTは、熱可塑性樹脂シートのみで構成されていても良いし、熱可塑性樹脂シートより厚さが厚い熱可塑性樹脂板で構成されていてもよい。また、被成型材料MTとして、繊維シート、樹脂シートおよびこれらのシートに面して充填材をそれぞれ配置したもので構成することもできる。この場合、充填材は、固形体であるペレット状や粘性を有する粘土状の熱可塑性樹脂材(例えば、ポリエチレン樹脂)を単体でまたはこの熱可塑性樹脂材にガラス繊維、炭素繊維または金属繊維などの繊維を混ぜたもので構成することができる。
In the third and fourth embodiments, the material to be molded MT is composed of a thermoplastic resin sheet and a fiber sheet. However, the material to be molded MT is appropriately selected according to the specification of the product PR.

It can be composed of a mixture of fibers.
また、さらには、被成型材料MTは、熱可塑性樹脂を熱した流動体であってもよい。すなわち、本発明における成型装置300は、射出成型機としても実施できるものである。また、このような射出成型機で構成された成型装置300においては、被成型材料MTとして熱可塑性樹脂の他に、熱硬化性樹脂、例えば、フェノール樹脂、メラミン樹脂、ユリア樹脂、ポリウレタン樹脂、エポキシ樹脂または不飽和ポリエステル樹脂を用いることもできる。また、これらの熱可塑性樹脂や熱硬化性樹脂に炭素繊維、ガラス繊維、金属繊維、金属粉末または各種鉱物粉末を混ぜ合わせたものを用いて射出成型することができる。
Furthermore, the molding material MT may be a fluid obtained by heating a thermoplastic resin.
