MOLD FOR STEERING WHEEL FOR AUTOMOBILE WITH THREE SPOKES

摘要

PROBLEM TO BE SOLVED: To control flow of molding material so as to set an overflowing hole at a position opposite to a central spoke molding part on a rim molding part when a position of a gate is displaced from a centerline of a steering wheel to prevent occurrence of a void fault due to entraining of the air upon casting of the molding material in a cavity of a mold for molding the wheel having three spokes. SOLUTION: A gate 4 is disposed at a position where is displaced to a side from a central spoke molding part 12 so that its direction and/or shape are decided in such a manner that much molding material to be cast in a cavity 11 is fed from the gate 4 toward the part 12 side and combined at an overflowing hole 5 provided at a position opposed to the part 12 on a rim molding part 11.
