Abstract:
A vent mechanism for a golf ball injection mold containing a spherical cavity in which a cover layer is applied to a golf ball core to form a dimpled golf ball, comprisinga solid pin coaxially arranged within a passage in the injection mold, the passage extending from the cavity along a radius of the golf ball through one of the poles thereof and having a non-circular end communicating with the cavity, said pin being operable between a normal position wherein an end of said pin closes said passage lower end, a retracted position wherein said pin end is arranged within said passage and spaced from the cavity to allow air to enter said passage from the injection mold cavity, and an extended position wherein said pin end is arranged within the cavity to eject a golf ball therefrom, said pin end having a non-circular cross-sectional configuration corresponding with that of said passage end, whereby a dimple formed by said pin at the pole of the golf ball has a non-circular configuration.
