Abstract
Injection molding apparatus having an elongated cooled mold core (,) which forms an inner side (,) of the cavity (,). The elongated mold core (,) extends through an opening (,) through a core lock member (,). The outer surface (,) of the mold core (,) and the inner surface (,) of the opening (,) through the core lock member (,) have matching parts (,) which taper inwardly towards the rear core (,) of the mold core (,). A nut (,) secures the mold core (,) to the core lock member (,) with the tapered parts (,) abutting against each other. The reverse taper of these parts (,) prevents injection pressure impact opening any space between them and thus prevents lateral core shift.
