Document Type and Number:
Japanese Patent JPH06182521
Kind Code:
A
Abstract:
PURPOSE: To provide a suction casting method where the product part of the casting and the stoke part need not be cut later in the suction casting method to pour the molten metal by using a stoke (sprue).
CONSTITUTION: A die 1 is placed at the upper part of a molten metal container, and the molten metal in the molten metal container is poured from the lower part into the cavity of the die through a stoke 4 due to the pressure difference. Then, the pressure difference is eliminated when the molten metal at the sprue part 12 becomes semi-solidified, and the stoke 4 is separated from the die 1.
