ABSTRACT:
A golf ball mold includes a pair of mold sections which are removably mated to define a spherical cavity therein, a plurality of support pins for supporting a core at the center of the cavity, and a degassing pin. At least one of the pins is provided at its distal end face with a projection for stamping a symbol. The mold is capable of stamping an identification mark on golf balls at the same time as their molding. The mark is successively stamped on the balls at a predetermined position to a constant clearness in a simple accurate manner.
