Abstract

PURPOSE: To eliminate fluctuations of molten metal feed amount and increase the yield, by providing an inner sleeve and a plunger sliding in a molten metal feeding sleeve, in a pressurizing casting machine having molten metal feeding sleeve in the vertical direction.
CONSTITUTION: Keeping dies 1, 2 in tight contact, an inner sleeve 8 is lowered to a molten metal feed port 11 provided in the middle of a hollow sleeve 5. By means of the inner sleeve 8 and a mutually slidable plunger 7, a molten metal holding part 9 of cavity part 3 is formed. Then, the molten metal is poured into the sleeve 5 by way of molten metal feed pipe 6 and molten metal feed port 11. Then, the inner sleeve 8 and plunger 7 are raised while keeping the mutual configuration. Then, when the die sprue 10a is equal to the diameter of plunger 7 or larger than the outside diameter of plunger and less than the outside diameter of inner sleeve 8, the inner sleeve 8 is stopped at the specified position, and the molten metal is filled into the cavity 3 by means of the plunger 7 alone then pressurized.
