ABSTRACT:
A quick change system for standard mold bases in a molding machine. Each half of a mold base has a support plate attached to the back surface. An adapter frame is mounted on the face of each platen of the press. Each adapter frame has a U-shaped guide channel for receiving a support plate and supported mold base half. A T-shaped guide roller is positioned on each side of the U-shaped guide channel to facilitate entry of a support plate into the guide channels. Apertures are provided in each adapter frame plate for fasteners for attaching the adapter frame plates to the platens. A knockout rod assembly is provided for ejecting the finished molded part from the mold base.
