Abstract

An injection press apparatus for molding/joining separate parts. The apparatus having a work table with first and second work stations for injecting material into a mold. A movable extruder/injection assembly is provided which has an extruder portion for extruding material, and an injection portion for injecting material. The extruder portion and injection portion are in fluid communication such that material is provided from the extruder portion to the injection portion prior to injection of material from the injection portion to the mold. The injection portion of extruder/injection assembly has a nozzle assembly for receiving and injecting material from the injection portion to a self-actuating mold clamp assembly at the first or second work stations. The first and second work stations support the mold clamp assembly which receives the molding material. The extruder/injection assembly is movable between the first and second work stations by a shuttle assembly.

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 stations
said 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;
and
said movable extruder/injection assembly is repeatably moved between said first and second work stations by a shuttle assembly.
