본 발명은 코아금형과 캐비티금형을 구비한 사출금형장치에서, 코아금형은 캐비티 형상에 따라 일정 두께로 절단되고 절단면에 밴딩히터를 내장한 가열코아와, 가열코아를 고정하며 냉각수단을 가지는 코아금형고정판을 포함하여 이루어지며;The present invention is an injection mold apparatus having a core mold and a cavity mold, the core mold is cut to a certain thickness according to the cavity shape and the heating core with a built-in banding heater on the cutting surface, and the core core having a cooling means and cooling means It comprises a fixed plate;

상기, 2차 단열공의 직경이 냉각수로단열공의 직경보다 크도록 구성하고;

The diameter of the secondary heat insulating hole is configured to be larger than the diameter of the heat insulating hole;
The present invention relates to a rapid heating cooling injection mold apparatus configured to position a cooling water insulating hole between secondary insulating holes.

본 발명은 또한 급속가열냉각 가능한 사출금형장치를 이용한 사출방법으로,The present invention is also an injection method using a rapid heating cooling injection mold apparatus,

사출성형 후 코아금형을 캐비티금형에서 분리시킨 후 냉각된 사출물을 분리시킴과 동시에 가열코아의 밴딩히터를 가열하는 가열공정;A heating step of separating the core mold after the injection molding from the cavity mold and separating the cooled injection molding product and simultaneously heating the bending heater of the heating core;

이어 코아금형을 캐비티금형과 캐비티를 형성하도록 결합하여 가열히터를 오프시키고 사출기로부터 용융합성수지를 캐비티로 공급하는 사출공정;An injection process of coupling the core mold to form a cavity and a cavity to turn off the heating heater and to supply the molten synthetic resin from the injection machine to the cavity;

사출작업 후 냉각수로단열공으로 냉각수를 공급하여 밴딩히터와 가열코아를 냉각시켜 캐비티의 사출물을 냉각시키며 2차단열공의 단열작용으로 가열코아의 캐비티 사출물을 집중 냉각하는 냉각공정;Cooling process for cooling the injection of the cavity by supplying the cooling water to the heat insulation hole with the cooling water after the injection operation to cool the injection of the cavity and the intensive cooling of the cavity injection of the heating core by the adiabatic action of the secondary heat insulation hole;

냉각 공정 후 냉각수 공급을 차단 후 냉각수를 배출시키고 냉각수단열공 및 2차단열공으로 기냉함과 동시에 코아금형을 이형시킨 후 사출물을 취출한 후 다음공정을 위하여 가열코아를 밴딩히터로 예비가열하는 사출물 추출공정을 순차 반복 수행하는 급속가열냉각 가능한 사출방법에 관한 것이다.After the cooling process, the cooling water supply is cut off, the cooling water is discharged, the air is cooled by the cooling means hot air and the secondary heat insulating air, the core mold is released, the injection molding is taken out, and the heating core is preheated by the banding heater for the next process. It relates to a rapid heating cooling injection method that performs the process repeatedly.

급속가열냉각 기술은 금형에서 캐비티 부근에 급속하게 가열하고, 급속하게 냉각시켜, 사출 생산성을 높이려는 목적으로 사용되고 있다.Rapid heating cooling technology is used for the purpose of rapidly heating and rapidly cooling the mold in the vicinity of the cavity to increase the injection productivity.

현재 사용되는 기술은 금형에 관체형 홀을 일정거리로 파서 히터를 끼우고, 여기에 냉각을 위하여 추가의 관체형 구멍을 파서 구멍으로 냉각이나 가열 열매체를 통과토록 하여 가열 및 냉각을 신속하게 변환시키는 구성이 국내특허등록 제 10-0890905호로 알려져 있으나, 금형 자체를 가열하여야 하므로 가열 열량이 커지고, 급속 가열시킨 것을 급속 냉각시키려하니 냉각 시간이 많이 걸려서 수율이 떨어진다.Currently used technology is to dig a tubular hole into a mold at a certain distance, insert a heater, and then dig an additional tubular hole for cooling and pass it through a hole or through a heating medium to quickly convert heating and cooling. Although the configuration is known as Korean Patent Registration No. 10-0890905, since the mold itself needs to be heated, the amount of heating heat increases, and rapid cooling of the rapid heating takes a lot of cooling time, resulting in a drop in yield.

또한, 금형에 일정 공간의 채널을 만들고, 그 채널에 히터를 내장시키고 히터외부와 채널 사이의 공간으로 냉온 열매체를 공급하여 급속 가열 및 냉각을 수행토록 하는 기술이 국내특허등록 10-0888985호로 알려져 있으나, 이 역시 전체의 금형을 가열 및 냉각하여야 하므로 열손실이 많은 실정이다In addition, there is a technique for making rapid heating and cooling by making a channel of a predetermined space in a mold, embedding a heater in the channel, and supplying a cold / hot heat medium to the space between the outside of the heater and the channel, but it is known as Korean Patent Registration No. 10-0888985. In addition, heat loss is high because the whole mold must be heated and cooled.

또한, 코아금형을 분리하여 중간코아금형판에 히터를 내장하고, 중간코아금형판과 코아금형은 스프링으로 탄발되는 가이드핀으로 결합하고, 코아금형에는 히터 가열 후 중간코아 금형판과 먼저 분리시켜 히터의 열기가 코아금형 전체에 전달되는 것을 막아주어 가열 및 냉각효율을 증진시킨 구조가 국내특허등록 제 10-0644922호로 개발되었으나, 중간코아금형판을 별도로 분리하여야하고, 가이드핀과 탄성스프링으로 결합하도록 구성하여야하므로 내구성이 떨어지고 금형 원가가 상승하는 문제점을 가진다.
In addition, the core mold is separated and the heater is embedded in the intermediate core mold plate, and the intermediate core mold plate and the core mold are combined with guide pins springed with springs, and the core mold is separated from the intermediate core mold plate after heating the heater. The structure that improves heating and cooling efficiency by preventing the heat from being transmitted to the entire core mold was developed in Korea Patent Registration No. 10-0644922, but the intermediate core mold plate should be separated separately, and combined with guide pins and elastic springs. Since it has to be configured, the durability and the mold cost rises.

본 발명은 이를 해결하고자 하는 것으로, 본 발명의 목적은 사출기와 연결된 캐비티금형과 이형 작용을 하는 코아금형에 밴딩히터의 열기를 캐비티 반대편의 코아금형 고정판에 일열의 냉각수로단열공과, 이열의 2차단열공을 형성하여 이중으로 단열작용하여 가열효과를 캐비티에 집중시켜 급속가열을 가능토록 하고, 냉각시에는 기냉효과를 증대시키도록 하는 급속가열냉각 가능한 사출금형장치 및 그 사출방법을 제공하려는 것이다.The present invention is to solve this problem, an object of the present invention is to heat the heat of the banding heater to the core mold connected to the injection molding machine and the core mold for releasing action in the core mold fixing plate on the opposite side of the cavity with a single row of cooling water insulated holes, It is to provide a rapid heat-cooling injection mold apparatus and an injection method for forming a hot hole so as to double heat insulation to concentrate the heating effect in the cavity to enable rapid heating, and to increase the air cooling effect during cooling.

냉각수로단열공(230)으로 냉각수(235)를 냉각수통(320)에서 냉각수밸브(341)가 오픈되었을 때 공급하여 냉각수통(320)으로 순환하도록 하는 냉각수펌프(340);A cooling water pump 340 for supplying the cooling water 235 to the cooling water heat insulating hole 230 when the cooling water valve 341 is opened in the cooling water tank 320 to circulate the cooling water tank 320;

냉각수밸브(341)가 닫히고 냉각수펌프(340)가 턴 오프될 때 오픈되는 에어밸브(331)와;An air valve 331 which is opened when the coolant valve 341 is closed and the coolant pump 340 is turned off;

에어밸브(331)를 통과하여 에어를 냉각수로단열공(230)으로 공급하는 에어펌프(330)와;An air pump 330 passing through the air valve 331 to supply air to the heat insulating hole 230;

Recognizing whether or not the set temperature of the temperature sensor 212 through the input terminal (I1) and recognizes the set temperature, the relay Ry is turned off through the output terminal (P5), the air pump 330 through the output terminal (P1) And a controller 300 for driving the coolant pump 340 through the output stage P2 and driving the coolant valve 341 and the air valve 331 through the output stage P3 and P4. . In the above description, the banding heater 211, the cooling water path insulation hole 230, and the secondary insulation hole 240 are formed in the core mold 200, but the same structure is symmetrically configured in the cavity mold as necessary. It is a well-known fact.

이와 같이 구성한 본원발명의 작동을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above are as follows.

도 1 및 도 5 와 같이 사출물(102) 취출한 다음, 다음 공정의 사출을 위하여 냉각수밸브(341)를 오픈시키고 냉각수펌프(340)를 구동시키도록 제어부(300) 출력단(P3)(P2)을 통하여 지령한다. 이어 냉각 후 제어부(300) 출력단(P3)(P2)의 출력 레벨을 변환시켜 냉각수밸브(341)를 닫고 냉각수펌프(340) 의 작동도 중지시키고 에어펌프(330)가 작동되어 냉각수로단열공(230)에 공기가 공급된다. 이와 동시에 코아금형(200)의 가열코아(210)와 코아금형 고정판(220)에 접합 밴딩히타(211)를 제어부(300) 출력단(P5)의 지령으로 릴레이(Ry)를 턴온시켜 전원부(310) 전원을 인가하여 코아금형(200)의 캐비티(201)가 있는 가열코아(210)를 가열시키는 가열공정(S10)을 수행한다. 이는 냉각수 공급을 중단하고 공기를 냉각수로단열공(230)에 채운 상태에서 가열코아(210)를 부위를 가열하므로 급속가열을 가능토록 한다. 이는 냉각수로단열공(230)과 2차단열공(240)이 이중으로 단열하므로(거기에 각 단열공이 수평상 교대로 배열되어) 캐비티 반대편으로의 열기를 별도의 냉각재료 없이 2열구조의 기냉방식으로 차단하므로 캐비티(201) 부위가 급속하게 집중적으로 가열되도록 기능한다.After the injection-molded product 102 is taken out as shown in FIGS. 1 and 5, the controller 300 output stages P3 and P2 are opened to open the coolant valve 341 and drive the coolant pump 340 for injection of the next process. Command through. Subsequently, after cooling, the output level of the output stages P3 and P2 of the control unit 300 are changed to close the coolant valve 341, stop the operation of the coolant pump 340, and the air pump 330 is operated to cool the heat insulating hole ( 230 is supplied with air. At the same time, the junction banding heater 211 is connected to the heating core 210 and the core mold fixing plate 220 of the core mold 200 by turning on the relay Ry by the command of the output terminal P5 of the control unit 300 to supply the power 310. A heating process (S10) is performed to heat the heating core 210 having the cavity 201 of the core mold 200 by applying power. This stops the cooling water supply and heats the heating core 210 in a state where the air is filled in the heat insulating hole 230 with the cooling water, thereby enabling rapid heating. This is because the cooling water insulating hole 230 and the secondary insulating hole 240 is insulated in a double (in which each heat insulating hole is arranged alternately horizontally), the heat to the other side of the cavity air cooling without a separate cooling material It blocks in such a way that the cavity 201 functions to rapidly and intensively heat up.

이어 도 2 및 도 6과 같이 고정된 캐비티금형(100)으로 코아금형(200)을 이동시켜 캐비티(201) 공간을 확보토록 하고 제어부(300)의 출력단(P5)을 통하여 밴딩히타(211)로의 전원부(310) 전원 공급을 중단시킨다. 동시에 사출기(101)의 용융 사출물을 게이트를 통하여 캐비티(201)로 공급하여 사출공정(S20)을 수행토록 한다. 여기서 밴딩히타(211)에 전원 공급을 중단하는 것은 가열코아(210)의 과열을 방지하기 위함이다.Subsequently, the core mold 200 is moved to the fixed cavity mold 100 as shown in FIGS. 2 and 6 to secure the cavity 201 space, and to the bending heater 211 through the output terminal P5 of the controller 300. Power supply unit 310 stops supplying power. At the same time, the molten injection of the injection machine 101 is supplied to the cavity 201 through the gate to perform the injection process (S20). Here, the power supply to the bending heater 211 is stopped to prevent overheating of the heating core 210.

이어 도 3 및 도 7과 같이 사출기(101)가 사출압력을 유지하는 가운데 제어부(300)는 출력단(P2)(P3)을 하이레벨의 출력신호를 인가하여 냉각수펌프(340)를 구동시키고, 냉각수밸브(341)를 오픈시켜(오픈시키는 것은 솔레노이드밸브 방식 등으로 구현 가능하므로 작동원리의 설명은 생략하고 단순히 오픈하는 것으로 설명한다) 도 10에 보인 냉각수통(320)의 냉각수(235)를 냉각수로단열공(230)으로 공급하여 배출구(230a)로 배출토록 하여 수냉을 이루도록 한다. 이러한 원리로 급속 냉각을 수행하는 냉각공정(S30)을 수행한다. 이 경우 냉각수(235)를 공급하는 냉각수로단열공(230)은 밴딩히타(211)와 2차단열공(240)사이에 위치하므로 뒷부분은 2차단열공(240)이 일정 간격으로 형성되어 있어 단열기능을 수행하므로, 냉각 효과는 주로 가열코아(210) 부위로 집중하여 나타나 급속 냉각의 요인이 된다. 이는 가열코아(210)와 코아금형고정판(220)을 별도로 분리하지 않고도 단열효과와 급속 냉각을 가능토록 하는 요인이 된다. 이 경우 도 7과 같은 구조는 냉각수로단열공(230)을 밴딩히타(211)와 나란한 1차냉각수로단열공(231)과, 2차단열공(240)뒤에서 밴딩히타(211)와 직각 방향으로 배열된 2차냉각수로 단열공(232)과 이들을 이어주는 연결냉각수로단열공(233)에 의하여 가열코아(210) 및 캐비티(201) 반대편을 집중 급속가열하므로 급속가열효과가 높게 된다.3 and 7 while the injection molding machine 101 maintains the injection pressure, the control unit 300 drives the coolant pump 340 by applying a high level output signal to the output stages P2 and P3, and the cooling water. By opening the valve 341 (opening can be implemented by a solenoid valve method or the like, a description of the principle of operation is omitted and simply described). The cooling water 235 of the cooling water container 320 shown in FIG. It is supplied to the heat insulating hole 230 to be discharged to the outlet 230a to achieve water cooling. In this principle, a cooling process (S30) for performing rapid cooling is performed. In this case, the cooling water path insulation hole 230 for supplying the cooling water 235 is located between the banding heater 211 and the secondary insulation hole 240, so that the rear portion has a secondary insulation hole 240 formed at a predetermined interval to insulate the heat. Since the cooling effect is mainly concentrated in the heating core 210, the cooling effect is a factor of rapid cooling. This becomes a factor to enable the thermal insulation effect and rapid cooling without separating the heating core 210 and the core mold fixing plate 220 separately. In this case, the structure shown in FIG. 7 has a primary cooling channel heat insulating hole 231 parallel to the banding heater 211 and a cooling heater 211 in a direction perpendicular to the bending heater 211 behind the secondary heat insulating hole 240. The rapid heating effect is high because the central heating core 210 and the cavity 201 opposite the heating core 210 are concentrated by the heat insulating holes 232 connected to the secondary cooling water and the connection cooling water insulating holes 233 connecting them.

이어 냉각공정(S30)을 마친 후에, 도 4 및 도 8과 같이 고정된 캐비티금형(100)에서 코아금형(200)을 분리(형개구동)시킨다. 이어 사출물(102)을 취출하는 사출물 취출공정(S40)을 수행토록 한다. 이어 냉각수밸브(341)의 닫음 작용과 냉각수펌프(340)의 턴오프를 제어부(300) 출력(로레벨) 지령에 의하여 수행토록 한다. 그리고 제어부(300) 출력단(P1)을 통한 하이레벨 인가로 에어펌프(330)를 구동시키고, 동시에 출력단(P4)으로 역시 하이레벨의 출력을 인가하여 에어밸브(331)를 오픈시키도록 지령한다. 이는 냉각수로단열공(230)으로 인가했던 냉각수를 배출구(230a)로 배출하여 냉각수통(320)에 보관시키고 대신 냉각수로단열공(230)은 공기로 채워 과 냉각을 막도록 한다. 즉, 가열코아(210)가 더 이상 냉각되는 것을 막아주어 반복되는 가열공정(S10)의 가열시간을 단축하도록 작용한다.Subsequently, after the cooling step S30, the core mold 200 is separated from the cavity mold 100 fixed as shown in FIGS. 4 and 8 (opening of the mold). Subsequently, the injection molding extraction process (S40) for taking out the injection molding product 102 is performed. Subsequently, the closing action of the coolant valve 341 and the turn-off of the coolant pump 340 are performed by the control unit 300 output (low level) command. In addition, the air pump 330 is driven by applying a high level through the output terminal P1 of the control unit 300, and at the same time, the air valve 331 is commanded to open by applying a high level output to the output terminal P4. This discharges the cooling water applied to the cooling water insulation hole 230 to the outlet 230a to be stored in the cooling water container 320, and instead, the cooling water insulation hole 230 is filled with air to prevent over cooling. That is, it prevents the heating core 210 from being cooled any more and serves to shorten the heating time of the repeated heating process (S10).

본 발명은 단순히 캐비티(201)의 곡면을 따라 밴딩히타(211)를 배열하고, 냉각수로단열공(230)과 2차단열공(240)을 이층 구조로 구분 구성하고, 각 냉각수로단열공(230)과 2차단열공(240)은 수평상으로 서로 엇갈리게 구성하였기로 소위 그물망을 촘촘히 설치한 것과 같은 단열효과를 이루어, 별도의 설비를 설치하지 않아도 기냉방식 만으로 급속가열과 급속 냉각을 가능토록 단열 하므로 사출물이 오목하거나 볼록한 형상의 사출물일때에도 별도의 가열 및 냉각에 따른 단열기구물 설치가 필요없이 가열 및 냉각시 단열 그 효과가 지대하다.
The present invention simply arranges the banding heater 211 along the curved surface of the cavity 201, and divides the coolant heat insulating hole 230 and the secondary heat insulating hole 240 into a two-layer structure, and each cooling water insulating hole 230 ) And the secondary heat insulation hole 240 are horizontally staggered with each other to achieve the insulation effect, such as the so-called tightly installed net, and to insulate so that rapid heating and rapid cooling only by the air-cooling method without installing a separate facility Even when the injection-molded product is a concave or convex shape, the effect of heat insulation during heating and cooling is great without the need for the installation of heat-insulating devices according to separate heating and cooling.
