ABSTRACT:
An improved golf ball injection mold is characterized by upper and lower support plates each containing corresponding hemispherical cavities which define spherical mold cavities when the plates are brought together. A plurality of retractable core pins are arranged in each cavity for supporting a core of a golf ball. A runner within the plates delivers fluid thermoplastic material to each cavity to form a cover on the golf ball core supported therein, and a cooling channel is provided adjacent to each cavity to provide even cooling of the thermoplastic material. Independently operated ejection assemblies are provided for the golf ball and for the residual thermoplastic material in the runner. With the improved ejection mold, the size and roundness of the golf ball and the surface configuration of the golf ball cover are more consistent and the molding time is reduced.
