Abstract

본 발명의 목적은 마그네슘 용탕을 밀폐시킨 로에 저압의 공기로 가압하여 마그네슘 용탕이 공급 통로를 따라 주형의 캐비티까지 용이하게 공급됨으로서 주조품의 산화 방지 및 작업의 안정성을 도모한 마그네슘 주조품 제조방법을 제공하는 데 있다.SUMMARY OF THE INVENTION An object of the present invention is to provide a method for producing a magnesium casting product by which magnesium molten metal is easily supplied to a cavity of a mold along a supply passage by pressurizing the furnace with a sealed magnesium molten metal with low pressure air. There is.

이를 실형하기 위한 본 고안은 상기한 주조품의 주형을 상측에 위치하도록 하는 커버에 의해 개구되는 용해로 등의 가열수단과; 상기 용해로가 가열됨에 따라 마그네슘이 용융되어 채워지는 도가니 등의 저장수단과; 상기 도가니에 채워진 용탕에 잠기도록 커버에 나사 결합되는 공급관 등의 관부재와; 상기 공급관을 통해 용탕이 주형에 공급되도록 도가니에 가압공기를 충진하는 가압장치 등의 가압수단을 포함하여 이루어지는 마그네슘 주조품의 제조방법을 특징으로 한다.The present invention for realizing this, and heating means such as melting furnace which is opened by a cover for positioning the mold of the casting above; Storage means, such as a crucible, in which magnesium is melted and filled as the melting furnace is heated; Pipe members such as supply pipes screwed to the cover to be immersed in the molten metal filled in the crucible; Characterized in that the manufacturing method of the magnesium casting comprising a pressing means such as a pressurizing device for filling the crucible with pressurized air so that the molten metal is supplied to the mold through the supply pipe.
