Hot runner nozzle for injection molding apparatus includes an alignment piece positioned between a tip removably attached to a nozzle body and tip surrounding piece removably connected to the nozzle body

摘要

Hot runner nozzle (16) for injection molding apparatus comprising manifold with runner(s) and mold component(14) defining mold cavity(ies) (24) which define gate includes alignment piece (40) between tip (36) attached to nozzle body (31) and tip surrounding piece (38) connected to nozzle body. The contacts between tip, alignment piece, tip surrounding piece and mold component are axially proximate the gate. The alignment piece contacts the tip surrounding piece to align the alignment piece with respect to the tip surrounding piece. The tip surround piece contacts the mold component to align the tip surrounding piece with respect to the gate. The nozzle body defines a nozzle body melt passage adapted to be in fluid communication with and downstream from the runner. The tip defines a tip melt passage downstream from and in fluid communication with the nozzle body melt passage. An Independent claim is included for injection molding apparatus.
