Abstract

본 발명은 주형을 제조할 때 사용하는 주물사 대신에 사용가능한 주형 보조충전재 및 이를 이용한 주형 제조 방법에 관한 것이다.The present invention relates to a mold auxiliary filler that can be used in place of a molding sand used when manufacturing a mold, and a mold manufacturing method using the same.

본 발명의 주형 보조충전재는 다면체 또는 구형볼의 형태로 세라믹 또는 애자 재질로 성형된다. 주형 보조충전재는 무게를 가볍게 하기 위하여 관통 구멍 또는 구형 중공부를 갖을 수 있다.The mold auxiliary filler of the present invention is molded of ceramic or insulator in the form of a polyhedron or a spherical ball. Mold auxiliary fillers may have through holes or spherical hollows to reduce weight.

주형 제조시에 조형될 주형의 모든 외측면에 일정 두께로 수지 및 경화제가 혼합된 주물사로 충진하고 나머지 부분은 모두 주형 보조 충전재로 충전된다. 이러한 주형 보조충전재는 별도의 처리없이 재사용 가능하고 전체 주형의 약 40% 내지 60%를 차지하므로, 주물사를 절약할 수 있다.At the time of manufacture of the mold, all the outer surfaces of the mold to be molded are filled with a molding sand mixed with a resin and a curing agent in a predetermined thickness, and all the remaining portions are filled with the mold auxiliary filler. These mold auxiliary fillers can be reused without any additional processing and take up about 40% to 60% of the total mold, thereby saving molding sand.
