ABSTRACT:
A mold assembly (100) formed of a pair of molds (102, 104) and a pair of release plates (118, 120). The molds (102, 104) have holes (126) which extend from outer surfaces into the mold cavities (106). The release plates (118, 120) have pins (122, 124) which pass into the holes (126, 128). When molding is finished, the molds (102, 104) are moved toward the release plates (118, 120). The pins (122, 124) contact the molded article(s) (134) and hold them in position as the molds (102, 104) are withdrawn.
