Abstract:
An injection press apparatus for joining work pieces comprising:a work table having first and second work stations where work pieces are joined, said first and second work stations including mounting structure for receiving said work pieces to be joined;a movable extruder/injection assembly for charging extrusion material into said work stations, said extruder/injection assembly having an extruder portion for extruding material and an injection portion for injecting extrusion material for joining work pieces, and supporting a stock portion for feeding stock directly to said extruder portion;said extruder portion and injection portion in fluid communication such that extrusion material is provided from said extruder portion to said injection portion;said injection portion of said extruder/injection assembly having a nozzle assembly receiving material from said injection portion for injecting extrusion material to said first or second work stations;said nozzle assembly having a first position allowing extrusion material to flow from said extruder portion to said injector portion but preventing extrusion material from flowing from said injection portion into said work stations, and a second position preventing extrusion material from flowing from said extruder portion to said injector portion but allowing extrusion material to flow from said injector portion to said work stationssaid first and second work stations including mounting structure for receiving said work pieces to be joined, and for engaging said nozzle assembly for supplying extrusion material for joining said work pieces, and a self-actuating mold clamp assembly having a generally clam shell configuration and supporting said mounting structure for receiving said work pieces and for engagement with said nozzle assembly for injecting material into said mold clamp assembly for joining said work pieces; andsaid movable extruder/injection assembly is repeatably moved between said first and second work stations by a shuttle assembly.
