The invention provides a golf ball mold that is composed 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 is formed between a plurality of mutually adjoining dimple-forming protrusions which include dimple-forming protrusions that lie across a parting line of the mold. Also provided is a golf ball molded using such a mold, and a golf ball manufacturing method which uses such a 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 production problems such as molding defects, scorching, core deformation and core eccentricity. |
