Abstract

본 발명은 철 또는 스테인레스 주형때 사용하는 중자 주사금형 및 외곽 주사금형을 조형하는 방법에 관한 것이다. 종래의 철 또는 스테인레스 주형때 사용하는 중자 주사금형 및 외곽 주사금형은 양각된 목형 및 음각된 목형을 지지틀에 체결한 후 이에 형성된 공실 내에 주사를 충입하여 애폭시수지로 고형화 시켜 주사로 된 중자금형 및 외곽금형을 얻어 이들 중자금형 외곽금형 사이에 형성된 공실(틈) 사이에 주물을 충입시켜 주형물을 주형하고 있는 바, 이때 주사금형은 1회 사용 후는 파괴시키는 1회용이기 때문에 계속하여 목형을 이용하게 되면목형 그 자체가 변형되어 주형물의 품질을 불량하게 함으로서 이와같은 폐단을 방지할 목적으로 목형 대용으로 알루미늄으로 대용금형을 조형하고 있으나, 이와같은 대용 금형은 무겁고 고가일 뿐만 아니라 표면을2차 가공 해야하기 때문에 사용상 및 제작상 난점이 있어 이는 원가 상승 원인 및 주형물의 품질 저하의 원인이 되고 있었던 것이다.The present invention relates to a method for molding a hollow injection mold and an injection injection mold for use in iron or stainless steel molds. The conventional injection mold and outer injection mold used in the conventional iron or stainless steel molds are formed by embossing the embossed wooden mold and the engraved wooden mold into the support frame, solidifying the injection mold with epoxy resin, And the outer mold is obtained, and the mold is filled by filling the cavity between the voids (gaps) formed between the outer molds of the inner molds. Since the injection mold is once used after being used once, The mold itself is deformed to deteriorate the quality of the mold. In order to prevent such deterioration, aluminum is used as a substitute for a wooden mold. However, such a substitute mold is heavy and expensive, There are difficulties in using and manufacturing because it has to be processed, which is the cause of cost increase and the quality of mold This will cause had been.

본 발명은 이상의 문제점을 해결하고자 발명인 것으로, 이의 발명 요지는 중자 금형 성형용 양각 목형 및 외곽 금형 성형용 음각 목형의 표면에 실리콘 고무층(2)(102), FRP수지층(3)(103), 석고층(4)(104) 및 외곽 형체 유지용 FRP수지층(3′)(103′)을 차례로 형성항 후 이를 지지틀 (5)(105)내에 끼움 설치하여 주입구(5′)(105′)를 통해 주사(모래)를 충입한 후 애폭시 수지액을 침투시켜 고형화 시킴으로서 중자 주사(鑄砂)금형은 매우 정교하며, 또한 종래의 알미늄 대용 금형에 비하여 가볍고 저염가액으로 양산이 가능하기 때문에 산업 발면에 크게 기여할 수있다.(2) 102, an FRP resin layer (3) (103), and an FRP resin layer (103) on the surface of an embossed wood for molding a hollow metal mold and a metal mold for molding an outer metal mold, The gypsum layer 4 104 and the FRP resin layer 3 'and 103' for retaining the outline body are formed in order and then inserted into the support frame 5 to form the injection port 5 ' ) Is injected through the injection (sand), then the epoxy resin solution is infiltrated and solidified, so that the injection molding die is very precise and since it is light and can be mass-produced with low salt solution as compared with the conventional aluminum substitute mold, It can greatly contribute to the surface appearance.
