摘要：An apparatus for injection molding using a stack mold comprising first andsecond mold assemblies interposed between a movable platen and a stationary platencomprises at least one centering device for coupling movement of the movable platen tointermediate mold members of the mold assemblies, the centering device comprising
first and second helical gear mechanisms and a transmission coupling rotation of helicalgear segments of the first and second helical gear mechanisms. Effective pitch of thehelical gear mechanisms and the ratio of rotation coupled by the transmission are chosento maintain the intermediate mold members centered in or offset from center in theseparation between the movable platen and stationary platen.
