摘要： A stack mold apparatus for forming plastic articles is described. The apparatus includes an insulated runner system for delivering molten plastic material to the mold spaces for forming the parts. The apparatus further includes a mechanism for ejecting the solidified material of the runner when it becomes necessary to change the plastic material being used. In a first embodiment, the ejector mechanism has a pair of movable plates that form part of the central mold portion of the stack mold. In a second embodiment, the ejector mechanism has a movable plate, forming half of the central mold portion, having sucker pins and ejector bars incorporated therein.

摘要： A clamp mechanism for selectively locking and unlocking a first member in a first position relative to a second member comprises a linkage system connecting the first and second members and drive means for articulating the linkage system for moving the first member relative to the second member. A fluid link is provided for locking the first member in position relative to the second member wherein the fluid link is actuated upon sensing the first member approaching the first position.

摘要： Method for tri-injecting a plurality of thermoplastic materials to mold an article having a layered wall structure using thermoplastic materials having different optimum processing temperatures including the maintenance of the optimum temperatures in flow paths individual to each material from its source at least to the injection nozzle. At least two of the nozzle channels are insulated to prevent heat transfer and to maintain the temperature of the thermoplastic materials.
