Abstract
A golf ball mold includes a pair of mold sections which are removably mated along a parting line to define a spherical cavity by their concave surfaces which are provided with a plurality of dimple-forming projections. Some dimple-forming projections are located across the parting line, and molding material injecting gates or fin-forming pits are located near the respective projections. After a seamless golf ball having dimples on the parting line Is molded, any abrasion of the dimples on the parting line can be effectively avoided in the subsequent step of grinding off the fins and burrs.
