Abstract
PURPOSE:To prevent the penetration of a molten metal into a casting sand and the collapse of a molding and to manufacture a casting of compact structure by solidifying a melting body with applying a high pressure further in succession after pressurizing by a gaseous body with a comparatively low pressure after filling a molten metal in the case of casting a casting with a full mold method. CONSTITUTION:The molten metal of an Al, etc., is filled from a sprue 10 into the full mold made by filling up a molding sand 9 at high density on the circumference of a polystyrene made lost-wax pattern 7 by arranging it inside a flask member 2, the lost-wax pattern 7 is burnt out and the molten metal is cast in the gap thereof. The gas generated in this case is eliminated from a pressure reducing port 2b, a gaseous body pressurizing device 3 is connected to the sleeve 6 of the circumference of the sprue 10 as well, and after preventing the penetration of the molten metal into a sand mold and the holding of the shape of a mold by pressurizing with a 1st low pressure until the solidified layer of the molten metal is formed on the mold surface it is solidified by pressurizing with the gaseous body of higher pressure. There are no collapse of the sand mold nor penetration of the molten metal into the casting sand and the casting of compact structure is obtd.
