Abstract

길게 연장되어 있는 세로구멍과, 그 세로구멍에 거의 직교하는 방향으로 연통하는 적어도 한쌍의 가로구멍을 구비하고 있는 예를 들자면 송급 파이프등의 가로구멍 부착관을 주조하는 방법으로서, 상기 세로구멍을 형성하기 위한 막대 형상의 센터핀이 주형의 캐비티 형성면에 대해서 미리 정해진 위치 관계가 되도록 상기 센터핀을 위치 결정하는 공정과, 상기 한쌍의 가로구멍을 형성하기 위한 한쌍의 주물발취판의 선단면이 상기 센터핀의 측면에 맞대이도록 상기 한쌍의 주물 발취판을 위치 결정하는 공정과, 상기 센터핀과 상기 한쌍의 주물 발취핀이 위치 결정된 후에 상기 캐비티내에 용탕을 충전하는 공정을 구비하고 있다. 이 주조 방법에 의하면 용탕은 센터핀이 한쌍의 주물 발취판에 의해 변형 방지된 상태에서 충전된다.The vertical hole is formed by casting a horizontal hole attachment pipe such as a supply pipe, for example, having a longitudinally extending longitudinal hole and at least one pair of horizontal holes communicating in a direction orthogonal to the vertical hole. Positioning the center pins so that the rod-shaped center pins have a predetermined positional relationship with respect to the cavity-forming surface of the mold, and the front end surfaces of the pair of casting plates for forming the pair of horizontal holes are And positioning the pair of casting extracting plates so as to face the side of the center pin, and filling the molten metal in the cavity after the center pin and the pair of casting extracting pins are positioned. According to this casting method, the molten metal is filled in a state where the center pin is deformed and prevented by a pair of casting plates.
