ABSTRACT:
A machine for making molds and molding cores (126) includes a pair of mold boxes (42a, 42b) removably mounted on a frame (60) for rotation between an upright, molding position in which molding material is introduced into the molding cavity of the molding boxes (42a, 42b) by a carrier (26) and an inverted discharge position in which the mold (126) is removed from the boxes by a mold receiving assembly (76). A pressure head assembly (46) both compresses molding material within the molding cavity and introduces a catalyst gas into the cavity for curing the molding material. A system for removing the spent gas from the molding cavity includes a pair of gas receiving chambers (122a, 122b) integral with the frame (60) which receives gas through the bottom of the mold boxes (42a, 42b) and an exhaust assembly (68, 70) which is selectively coupled with exhaust ports (124a, 124b) in the chambers (122a, 122b ). A mold transfer carriage (84) transfer molds (126) discharged from the mold boxes (42a, 42b) to either of two lateral positions and can be employed to automatically change mold boxes (42a, 42b) which are mounted on the frame (60) by quick release connections (62, 64, 134).
