ABSTRACT:
A golf ball mold includes a pair of mold sections which are removably mated along a parting surface to define a spherical cavity by their concave surfaces. The concave surfaces are provided with a plurality of dimple-forming projections. Some dimple-forming projections are integrally formed in one mold section at the parting surface as raised knobs that protrude in a transverse direction over a distance of 1/2 to 1/4 of the projection diameter, and the other mold section is provided at the parting surface with recesses for receiving the raised knobs. Using the mold, seamless golf balls with improved flight performance can be molded.
