A core side of a mold includes a mold surface against which the article bears during molding, a core pull and an ejector pin. The core pull includes a protuberance moveable between an extended position in which the protuberance protrudes beyond the mold surface, and a retracted position in which the protuberance does not substantially protrude beyond the mold surface. The ejector pin includes an end moveable between an extended position in which the end protrudes beyond the mold surface, and a retracted position in which the end does not substantially protrude beyond the mold surface. The protuberance is in the extended position and the ejector pin end is in the retracted position during a part retaining portion of a mold cycle, while the protuberance is in the retracted position and the ejector pin end is in the extended position during a part ejecting portion of the mold cycle.
