Abstract
PURPOSE: To perform titled casting under high productivity without producing any defects in the part contacted with an upper die by holding at least part of the upper die above the molten metal surface during pouring and pushing it into the molten metal after the completion of pouring.
CONSTITUTION: In the state that a lower die 1, a side die 2, an upper shell mold 3 and a shell core 4 are held set, molten metal 6 of molten Al alloy or the like is poured through a sprue 5. During this pouring, an upper die 7 is positioned above away from the surface of the molten metal 6. When the surface of the molten metal 6 reaches the position B higher by a certain degree from the portion below the A-A line to become the product, the pouring is stopped and preferably the slag etc. of the molten metal surface are removed. Thence, the upper die 7 is lowered by a hydraulic cylinder etc. and is pushed into the molten metal 6 down to the chain line position. In this state, the molten metal 6 is allowed to freeze, after which the respective dies are disassembled and the core is removed. The thus obtained casting is cut in the A-A line position, whereby the product having intricate shapes and thin-walled parts such as 4-cycle cylinder head is obtained.
