ABSTRACT:
The present invention is directed to a retractable sleeve for a golf ball injection mold for forming a golf ball cover or intermediate layers of a golf ball. The retractable sleeves engage with a golf ball core to securely position the core within the injection mold and may be used to strike the golf ball out of the mold cavity after the injection molding process is completed. The faces of the retractable sleeves may be shaped to conform to the curvature and texture of the cavity wall of the golf ball mold.
