Golf ball injection mold

摘要

A golf ball injection mold defines a spherical cavity therein. A parting plane is situated substantially at an equator of the cavity. A plurality of gates are disposed nearly along the equator. At least one gate is disposed nearly at a position corresponding to the cavity's north pole and at least one gate disposed nearly at a position corresponding to the cavity's south pole. A molding material is injected from an injection molding machine into the cavity through the gates. A steric arrangement of gates adapted to the cavity geometry permits a cover or intermediate layer of a uniform thickness to be formed around a core.
