  • Patent number: 5783224
    Abstract: A reconfigurable injection mold machine (10) having a fixed mold body (60, 60') and two movable mold bodies (62, 62' and 64, 64') that can be automatically repositioned with respect to each other to make different mold cavities for molding different parts. The three mold bodies (60,60', 62,62' and 64,64') each include a laminate subassembly (140,140', 142,142', 144,144') composed of a plurality of laminates (162,162', 164,164', 204,204', 234,234') and a mounting frame (146,146', 192,192', 218,218') arranged to hold and position the laminates during assembly to the mold. The mounting frame permits preassembly of the laminates on the workbench into a subassembly (140,140', 142,142', 144,144') that is then easily inserted into an opening in the mold (60,60', 62,62' and 64,64') and secured in place.

  • Patent number: 5731013
    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.
