Classification: CPC B | IPC B

Claim 0:
1. A mold comprising:
an upper mold cavity;
a lower mold cavity, wherein each mold cavity has an arcuate inner surface defining an inverted dimple and fret pattern; and the upper mold cavity and a lower mold cavity collectively create a mold having an interior spherical cavity for holding a golf ball subassembly when mated together to provide a mated mold
a plurality of retractable pins; and
a plurality of injection gates spaced circumferentially about the mold wherein each injection gate is made up of a first portion in the upper mold cavity and a second portion in the lower mold cavity,
wherein the mated mold has a wave-shaped parting line that extends circumferentially about the mold at an interface between the upper mold cavity and the lower mold cavity,
wherein the wave-shaped parting line contacts fret portions of the inverted dimple and fret pattern without contacting any dimple portion of the inverted dimple and fret pattern,
wherein the plurality of injection gates are spaced circumferentially about the mold within the wave-shaped parting line at an interface between the upper mold cavity and the lower mold cavity without intersecting any dimple of the dimple and fret pattern,
wherein the dimple and fret patterns of the upper mold cavity and the lower mold cavity each includes at least a plurality of first dimples adjacent the wave-shaped parting line and a plurality of second dimples adjacent the wave-shaped parting line, wherein the first dimples are smaller than the second dimples,
wherein each injection gate has a center that is located at an intersection of the wave-shaped parting line and a phantom equator that extends circumferentially about the mold, and
wherein at least one injection gate includes a first portion positioned directly between the wave-shaped parting line and a first dimple in the dimple and fret pattern of the upper mold cavity, and at least one injection gate includes a second portion positioned directly between the wave-shaped parting line and a first dimple in the dimple and fret pattern of the lower mold cavity.
