ABSTRACT:
A reconfigurable injection mold machine (10) is disclosed having movable mold bodies (62, 62' and 64, 64') that can be automatically repositioned with respect to each other to mate different mold cavities for molding different parts. The machine includes a stationary A-side frame (14) having an A-side mold assembly (18) attached thereto and a movable B-side frame (16) having a B-side mold assembly (20) attached thereto. Each mold assembly includes a first mold body (60, 60') attached thereto and third and second mold bodies (62, 62' and 64, 64') that are coupled thereto and arranged for movement and repositioning with respect to the first mold body (60, 60'). The third and second movable mold bodies (62, 62' and 64, 64') include a traveling separator assist (150) arranged in the A-side portion of the movable mold body (64) that moves along therewith. The traveling separator assist (150) is operable to eject the molded part from the A-side portion mold cavity (104) during movement of the movable frame (16) to the open position so that the molded part remains in the B-side portion mold cavity (104'). The traveling separator assist (150) is operational in all operating positions of the mold bodies.
