ABSTRACT:
An apparatus for injecting molding material into a self-clamping mole. The apparatus includes a support frame with spaced plates and support bars interconnecting the plates, and a C-shaped opening formed in the plates. An injector is included for injecting molding material into the self-clamping mold under pressure, and an extruder for providing molding material to the injector. Temperature controllers are also provided for controlling the temperature of the molding material within the injector and extruder. A lift mechanism supported on the frame provides clamped engagement between the self-clamping mold and the frame. During the injection operation wherein the injector is engaged with the mold, the lift mechanism clamps the mold to resist internal mold forces resulting from the injection of molding material.
