Abstract

본 발명은 실리콘과 에폭시로 구성된 진공 주형용 몰드 및 그 제조방법에 관한 것으로서, 종래 실리콘재료로 사용한 진공 주형용 몰드 외부를 상기 실리콘에 비해 가격측면에서 유리한 에폭시로 대체하고, 제품이 되는 용탕과 맞닿는 부분만을 실리콘으로 사용하며 상기 진공 주형용 몰드의 상, 하부 몰드의 체결장치를 설치할 수 있도록 개선하므로써, 상기 진공 주형용 몰드의 제작비를 절감할 수 있고, 몰드 상, 하부의 체결력 향상으로 피가공물의 변형을 방지할 수 있는 실리콘과 에폭시로 구성된 진공 주형용 몰드 및 그 제조방법을 제공하고자 한 것이다.The present invention relates to a vacuum mold mold composed of silicon and epoxy and a method of manufacturing the same, wherein the outside of the vacuum mold mold conventionally used as a silicon material is replaced with epoxy, which is advantageous in terms of price compared to the silicone, and is in contact with a molten metal that is a product. By using only silicon as a part and improving the fastening device for the upper and lower molds of the vacuum mold, the manufacturing cost of the vacuum mold can be reduced, and the tightening force of the mold and the lower part can be improved. An object of the present invention is to provide a mold for vacuum casting composed of silicone and epoxy and a method of manufacturing the same.
