Patent ID: 7829005

Claim:
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 with a first radius, a first taper section with a second radius smaller than the first radius, a second taper section with a third radius smaller than the second radius, and the first mold half having a second pin having a base with a first radius, a first taper section with a second radius smaller than the first radius, and a second taper section with a third radius smaller than the second radius, the second mold half having a first bushing with a main cavity having a main cavity with a first diameter, a first cavity with a second diameter smaller than the first diameter of the main cavity, and a second cavity with a third diameter smaller than the second diameter, the first pin of the first mold half engaged within the first bushing of the second mold half, the second mold half having a second bushing for engagement with the second pin of the first mold assembly, the second bushing having a main cavity with a first diameter, a first cavity with a second diameter smaller than the first diameter of the main cavity, and a second cavity with a third diameter smaller than the second diameter; exerting a lateral force on the second mold half by a spring assembly wherein the spring assembly exerts pressure on the second mold half ranging from 300 to 500 pounds per square inch; separating the first mold half from the second mold half, wherein the first mold half is separated from the second mold half along a vertical axis; and forcing the second mold half to be laterally displaced from the first mold half along a horizontal axis perpendicular to the vertical axis.
