Patent ID: 7547208

Claim:
An injection molding apparatus comprising: a manifold having at least one manifold melt channel for receiving a melt stream of moldable material under pressure; a first nozzle having a first nozzle melt channel in fluid communication with said manifold melt channel; a second nozzle having a second nozzle body, a second nozzle melt channel in fluid communication with said first nozzle melt channel and a plurality of outwardly extending melt passages in fluid communication with said second nozzle melt channel; a nozzle link provided between the first nozzle and the second nozzle and having a nozzle link melt passage for fluidly coupling the first nozzle melt channel and the second nozzle melt channel, a plurality of gate seals coupled to said second nozzle, said plurality of gate seals for delivering the melt stream from said plurality of outwardly extending melt passages to a plurality of mold cavities through respective mold gates; a shut-off valve disposed within a bore in said second nozzle body, wherein said bore intersects with one of said outwardly extending melt passages, wherein said shut-off valve includes a passage therethrough such that when said passage is aligned with said outwardly extending melt passage, the melt stream may flow through said shut-off valve, and when said passage is aligned substantially perpendicular to said outwardly extending melt passage, the melt stream is prevented from flowing past said shut off-valve.
