Abstract

1. 청구범위에 기재된 발명이 속한 기술분야1. TECHNICAL FIELD OF THE INVENTION

본 발명은 엔진의 실린더 헤드등의 주물을 제조하는 저압주조장치에 관한 것이다.The present invention relates to a low pressure casting apparatus for producing castings such as cylinder heads of an engine.

2. 발명이 해결하려고 하는 기술적 과제2. The technical problem to be solved by the invention

실린더 헤드등의 주물의 저압주조장치에 있어서 탕구부근의 용탕의 응고를 억제하는 것으로 주조결함의 발생을 방지하고자 하는 것이다.In the low pressure casting apparatus of castings, such as a cylinder head, to suppress the solidification of the molten metal near a mouth, it is aimed at preventing the casting defect.

3. 발명의 해결 방법의 요지3. Summary of the Solution of the Invention

실린더 헤드를 주조하는 주형캐버티(4)의 배기포트 측 측벽의 모래형(13)으로 구성되고 있고, 다른 측벽 및 상하벽은 금형(6)∼(8)로 구성되고, 주형 캐버티(4)의 측부에는 탕류부(1)이 설치된다. 용탕유지로에서 상승한 용탕은 탕류부(1)에서 모래형(13)에 설치된 탕구(5)를 통하여 주형캐버티(4)에 유입된다. 모래형(13)의 단열성과 탕류부(1)의 용탕의 열용량이 큼에 따라 탕구(5)에서 용탕의 응고가 억제되어 밀어주는 탕의 효과가 취후까지 유지된다.It consists of the sand mold 13 of the side wall of the exhaust port side of the mold cavity 4 which casts a cylinder head, and the other side wall and the upper and lower walls are comprised from the metal mold | die 6-(8), and the mold cavity 4 The water supply part 1 is provided in the side part of (). The molten metal which rises from the molten metal holding path flows into the mold cavity 4 through the pouring hole 5 installed in the sand mold 13 in the molten metal flow part 1. As the thermal insulation of the sand mold 13 and the heat capacity of the molten metal of the molten metal part 1 are large, the solidification of the molten metal is suppressed in the molten iron 5 and the effect of the molten water is maintained until after cooking.

4. 발명의 중요한 용도4. Important uses of the invention

본 발명은 엔진의 실린더 헤드등의 주물을 제조하는 저압주조장치에 관한 것이며 특히 주조장치에 있어서 탕구부근의 용탕의 응고를 억제하여 주조결함의 발생을 방지하는 것에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a low pressure casting apparatus for producing castings, such as an engine cylinder head, and more particularly, to suppressing solidification of molten metal near a hot water ball in a casting apparatus to prevent casting defects.
