ABSTRACT:
A core pin is aligned and longitudinally positioned with respect to an associated injection mold by a support unit which has adjusting elements remote from the injection mold for adjusting the core pin in X, Y, and Z planes. The adjusting elements, in their simplest forms, are headed members lying along X, Y, and Z axes of the core pin with the threaded members being adjustably threaded into the support unit and having heads engaging flats on the core pin. The core pin is shiftable in the Z plane relative to the injection mold for example through a toggle assembly in which event the core pin is adjusted and guided in the X and Y planes by means of a guide ring which is adjustably positioned, and the toggle linkage is carried by a turn buckle permitting adjustment of the core pin in the Z plane.
