ABSTRACT:
An injection molding nozzle is disclosed in which the body has a front end and a central bore terminating at the front end, the front end receiving a needle assembly. The needle assembly has an outer retaining piece adapted to be removeably secured to the front end of the body. The inner piece of the needle assembly is adapted to be received within the outer retaining piece and includes a gating needle that extends through the central opening of the outer retaining piece so as to be in close proximity to the gate of the mold cavity. One or more spacers are provided that are selectively positioned between the inner piece and a shoulder in the front end of the body and a shoulder in the outer retaining piece, thus permitting adjustable axial positioning of the gating needle with respect to the central opening of the outer retaining piece.
