Abstract
An improved apparatus comprising a three plate mold for forming golf ball cores having dual parting lines. The mold comprises top, center and bottom plates, each having at least one mold insert with each insert having a cavity therein. The three cavities collectively form a spherical shape for molding a golf ball core. Upon the cores being formed, the center plate holding the cores, is lifted and rotated to a juxtaposed position against a stripping plate, whereby the cores are mechanically separated from both the mold and overflow flashing.
