Description

【０００１】
【発明の属する技術分野】
本発明は、原型の原料およびその製造方法に関するものである。
【０００２】
【従来の技術】
従来、原型（プロトタイプ）は押し出し鋳込み工程のような方法によって作られる物品の製造に必要とされる。原型は、所望の物品を迅速に成形するために用いられる鋳型（モールド）などを作るのに用いられる。原型は通常、木材や金属材料で製造される。
【０００３】
【発明が解決しようとする課題】
しかしながら、木材は多量の繊維や木目を含んでいるため、木材で作られた原型はなめらかな外観をもたない。加えて、木材は湿気を吸収しやすく、変形して壊れやすい。さらに、木材は強度が低い。一方、金属材料は重く、加工に時間がかかる。加えて、金属材料は強度が高く固いが、それによって形の修正が容易ではない。
したがって、本発明の主な目的は、上記問題を解決し、適切な強度をもち、かつ加工のしやすい原型の原料およびその製造方法を提供することにある。
【０００４】
【課題を解決するための手段】
本発明の原型の原料を製造する方法は、（ａ）所定量の中空粉と所定量の樹脂を供給する工程と、（ｂ）中空粉と前記樹脂とを混合および撹拌し、混合材料とする工程と、（ｃ）混合材料から中空粉と樹脂との間に形成された気泡を除去する吸引工程と、（ｄ）混合材料を所定の形に形成する工程と、（ｅ）混合材料を第１の一定温度で第１の所定時間保持し、中空粉と樹脂を結晶化および硬化する工程と、（ｆ）混合材料を第２の温度で第２の所定時間加熱し、中空粉と樹脂をさらに結晶化および硬化して原料を形成する工程と、（ｇ）原料を取り出す工程と、（ｈ）原料を仕上げする工程とを含む。
【０００５】
本発明の原型の原料は、所定量の中空粉と、中空粉とともに混合され硬化された所定量の樹脂とを備え、所定の構造強度をもつように形成される。
【０００６】
【発明の実施の形態】
以下、本発明の実施例を図１〜３に基づいて説明する。
本実施例の製造方法では、鋳型を作るのに用いられる原型の原料を製造する。原料は図２、図３に示すように、多数の中空形状に形成された中空粉１０と、中空粉１０とともに硬化される樹脂１１の混合物とを含み、所定の構造強度になるように形成されている。中空粉１０のそれぞれは、内部にスペース１２を有する。中空粉１０は、セラミック、ガラス、樹脂などに製造される。樹脂１１は、エポキシ樹脂、ポリエチレン樹脂、ポリプロピレン樹脂、ポリエステル樹脂などよりなる。
【０００７】
本実施例による製造方法は、図１のフローチャートに示すように、以下のステップを含む。
（ａ）原料供給ステップ
所定量の中空粉１０と所定量の樹脂１１を供給する。
【０００８】
（ｂ）混合ステップ
中空粉１０と樹脂１１とを混合および撹拌し、混合材料とする。
（ｃ）気泡吸引ステップ
混合材料から中空粉１０と樹脂１１との間に形成された気泡を除去する。
【０００９】
（ｄ）成型ステップ
混合材料を図示しないダイに入れることにより、所定の形に形成する。
（ｅ）定温保持ステップ
混合材料を−１０℃〜−２０℃の範囲の一定温度で４時間〜１２０時間保持し、中空粉１０と樹脂１１を結晶化および硬化する。
【００１０】
（ｆ）第２の保持ステップ
混合材料を６０℃〜１１０℃の温度で４時間から８時間に加熱して、中空粉１０と樹脂１１をさらに結晶化および硬化して原料を形成する。
（ｇ）原料取り出しステップ
上記ステップ（ａ）〜（ｆ）で形成された原料を取り出す。
（ｈ）仕上げステップ
ステップ（ｇ）で取り出したげ原料を仕上げする。
【００１１】
上記ステップ（ａ）において、所定量の中空粉とは、重量で樹脂１００単位に対し、中空粉２〜５０単位であることが望ましい。
上記ステップ（ｅ）において−１０℃〜−２０℃の範囲の一定温度で４時間〜１２０時間保持されるため、中空粉１０と樹脂１１は徐々に結晶化および硬化し、純度の高い完全な結晶が形成される。
【００１２】
ステップ（ｆ）では、混合材料は６０℃〜１１０℃の温度で４時間〜８時間加熱されるため、中空粉１０と樹脂１１は全体が結晶化および硬化し、混合材料の硬度と安定性が高められる。一定温度での硬化するステップ（ｅ）と第２の硬化ステップ（ｆ）とを組み合わせることにより、原型が縮んだり変形したりするのを防止することができ、靱性や安定性を向上させることができる。
【００１３】
中空粉１０は、樹脂１１に保護されているが、それらの間には小さなギャップがある。加えて、樹脂１１自体が所定の弾力と靱性をもつため、中空粉１０と樹脂１１とでつくられた本実施例の原型の構造強度は、金属よりも小さく、木材よりは大きくなる。そのため、原型は容易に加工ができ、かつ十分な強度をもち、重量も減らすことができる。加えて、本実施例の原型は湿気を吸収せず、容易には変形しないので、容易に湿気を吸収して変形しやすい木材による原型がもつ問題点を解決することができる。さらに、本実施例の原型は容易に加工ができ、容易に形を修正できるため、金属材料による原型がもつ加工が難しく形の修正がし難いという問題点を解決することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a prototype raw material and a method for producing the same.
[0002]
[Prior art]
Conventionally, prototypes (prototypes) are required for the manufacture of articles made by methods such as an extrusion process. The prototype is used to make a mold or the like that is used to quickly form a desired article. The prototype is usually made of wood or metal material.
[0003]
[Problems to be solved by the invention]
However, since wood contains a large amount of fibers and grain, the prototype made of wood does not have a smooth appearance. In addition, wood is easy to absorb moisture, deform and break easily. Furthermore, wood is low in strength. On the other hand, the metal material is heavy and takes time to process. In addition, the metal material is strong and hard, which makes it difficult to correct the shape.
Accordingly, a main object of the present invention is to solve the above-mentioned problems, to provide a prototype raw material having an appropriate strength and easy to process, and a method for producing the same.
[0004]
[Means for Solving the Problems]
The method for producing the original raw material of the present invention includes (a) a step of supplying a predetermined amount of hollow powder and a predetermined amount of resin, and (b) mixing and stirring the hollow powder and the resin to obtain a mixed material. A step, (c) a suction step of removing bubbles formed between the hollow powder and the resin from the mixed material, (d) a step of forming the mixed material into a predetermined shape, and (e) A step of crystallizing and curing the hollow powder and the resin at a constant temperature of 1 for a first predetermined time; and (f) heating the mixed material at a second temperature for a second predetermined time, Further, it includes a step of crystallizing and curing to form a raw material, (g) a step of taking out the raw material, and (h) a step of finishing the raw material.
[0005]
The original raw material of the present invention includes a predetermined amount of hollow powder and a predetermined amount of resin mixed and cured together with the hollow powder, and is formed to have a predetermined structural strength.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to FIGS.
In the manufacturing method of the present embodiment, an original material used for making a mold is manufactured. As shown in FIGS. 2 and 3, the raw material includes a large number of hollow powders 10 formed in a hollow shape and a mixture of resins 11 that are cured together with the hollow powder 10, and is formed to have a predetermined structural strength. ing. Each of the hollow powders 10 has a space 12 inside. The hollow powder 10 is made of ceramic, glass, resin or the like. The resin 11 is made of epoxy resin, polyethylene resin, polypropylene resin, polyester resin, or the like.
[0007]
The manufacturing method according to the present embodiment includes the following steps as shown in the flowchart of FIG.
(A) Raw material supply step A predetermined amount of hollow powder 10 and a predetermined amount of resin 11 are supplied.
[0008]
(B) Mixing step The hollow powder 10 and the resin 11 are mixed and stirred to obtain a mixed material.
(C) Air bubble suction step The air bubbles formed between the hollow powder 10 and the resin 11 are removed from the mixed material.
[0009]
(D) Molding step The mixed material is put into a die (not shown) to form a predetermined shape.
(E) Constant temperature holding step The mixed material is held at a constant temperature in the range of −10 ° C. to −20 ° C. for 4 hours to 120 hours to crystallize and cure the hollow powder 10 and the resin 11.
[0010]
(F) The second holding step mixed material is heated at a temperature of 60 ° C. to 110 ° C. for 4 to 8 hours, and the hollow powder 10 and the resin 11 are further crystallized and cured to form a raw material.
(G) Raw material extraction step The raw material formed in the above steps (a) to (f) is extracted.
(H) Finishing step The raw material taken out in step (g) is finished.
[0011]
In the step (a), the predetermined amount of hollow powder is desirably 2 to 50 units of hollow powder with respect to 100 units of resin by weight.
In the above step (e), the hollow powder 10 and the resin 11 are gradually crystallized and hardened at a constant temperature in the range of −10 ° C. to −20 ° C. for 4 hours to 120 hours. Is formed.
[0012]
In step (f), since the mixed material is heated at a temperature of 60 ° C. to 110 ° C. for 4 hours to 8 hours, the hollow powder 10 and the resin 11 are entirely crystallized and cured, and the hardness and stability of the mixed material are increased. Enhanced. By combining the step (e) of curing at a constant temperature and the second curing step (f), the original mold can be prevented from shrinking or deforming, and toughness and stability can be improved. it can.
[0013]
The hollow powder 10 is protected by the resin 11, but there is a small gap between them. In addition, since the resin 11 itself has predetermined elasticity and toughness, the structural strength of the prototype of this embodiment made of the hollow powder 10 and the resin 11 is smaller than that of metal and larger than that of wood. Therefore, the prototype can be easily processed, has sufficient strength, and can reduce the weight. In addition, since the prototype of this embodiment does not absorb moisture and does not easily deform, it is possible to solve the problems of the prototype made of wood that easily absorbs moisture and easily deforms. Furthermore, since the prototype of this embodiment can be easily processed and the shape can be easily corrected, it is possible to solve the problem that it is difficult to process the shape of the prototype using the metal material and the shape is difficult to correct.
