Description

주형의 성형 방법Molding method of the mold

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 주물 모래를 거푸집에 충전하는 공정도; 제2도는 기체를 도입하기 위한 통기성 통체를 사형 내에 밀어 넣는 상황을 보이는 그림; 제3도는 전기 통기성 통체와 가압된 고온의 기체 공급원과의 사이의 접속을 보이는 그림.1 is a process chart of filling the die with sand casting; 2 is a diagram showing a situation in which a breathable cylinder for introducing a gas is pushed into a sandpaper; 3 is a diagram showing the connection between an electrically breathable cylinder and a pressurized hot gas source.
