Abstract
A golf ball mold that is provided that has of a plurality of mold parts which removably mate to form a cavity having an inner wall with a plurality of dimple-forming protrusions thereon, wherein a non-circular resin injection port for injecting into the cavity a resin material is formed between a plurality of mutually adjoining dimple-forming protrusions which include a plurality of dimple-forming protrusions that lie across a parting line of the mold. By using the golf ball mold of the invention, even when manufacturing golf balls with a high dimple surface coverage on which the dimples are tightly arranged, particularly up to the vicinity of the resin injection port, imbalances in the resin injection pressure and flow rate during injection molding are suppressed, enabling golf balls to be manufactured without giving rise to production problems such as molding defects, scorching, or deformation and eccentricity of the core.
