Abstract:
1. A method for de-molding a plurality of golf balls or golf ball precursor products from an injection mold assembly, the method comprising: injecting a polymer material into a plurality of cavities of a mold to form a layer for a golf ball, the mold comprising a first mold half and a second mold half engaged together, the first mold half having a first pin comprising a base, a first taper section and a second taper section, the second mold half having a first bushing with a first cavity, a second cavity and a third cavity, the first pin of the first mold half engaged within the first bushing of the second mold half; exerting a lateral force on the second mold half by use of a spring assembly; vertically separating the first mold half from the second mold half a first vertical distance corresponding to a depth of the first cavity and laterally moving the second mold half relative to the first mold half a first lateral distance, the first lateral distance corresponding to a radius of the first cavity; and vertically separating the first mold half from the second mold half a second vertical distance corresponding to a depth of the second cavity and laterally moving the second mold half relative to the first mold half a second lateral distance, the second lateral distance corresponding to a radius of the second cavity minus the radius of the first cavity.
