Abstract

PURPOSE: To reduce the solidification time for a feeder head, and improve the performance of casting work by cooling the feeder head part quickly to allow the same to solidify at the point of the time when the body of a casting ends solidifying in casting the casting by using the feeder head.
CONSTITUTION: At the time of casting a casting by teeming molten metal into a casting cavity 3 formed on molds 1, 2 and having a feeder head part 5, the solidification of the molten metal progresses from the lower part to the upper part in the cavity 3, and a solenoid valve 9 is opened by a timer 12 adjusted to the time when the part in the uppermost part B2 in the cavity 3 ends solidifying, whereby cooling air is fed from an air compressor 10 into the space 7 provided in the outside circumferential part in the part 5, and is discharged through a discharge pipe 13. The cooling air cools quickly the remaining feeding molten metal 5 played the role of a feeder head via a thin wall 4 for forming the feeder heat part, and solidifies the same in a short time, so that it is solidified in the time shorter than the time required for the natural solidification of the feeder head and the cycle time of the casting is reduced, whereby the performance of casting work is improved.
