Abstract

PURPOSE: To enable a grease storage part to be simultaneously molded in an inner periphery of an axle insertion hole when a plastic wheel is molded, by a method wherein an expansion is formed on an axle mold for molding and axle insertion hole.
CONSTITUTION: A mold for injection-molding a plastic wheel consists of a movable mold 1, formed of a core bush 1a, a core plate 1b, and a mold attaching disc 1c, and a fixed mold 2, and particularly a drum-shaped expansion 17 is formed on the middle of the axle mold 3. A high-molecular material is poured by injection in an axle molding chamber 4 through a runner 20 to mold a wheel and to simultaneously mold a grease storage part in the inner periphery of the axle insertion hole.
