Abstract
A collapsible mold core assembly facilitates formation of features such as channels and undercuts in interior regions of molded articles. The assembly includes a central, fixed pyramidial base member having a first plurality of obliquely oriented channels which receive a like plurality of first mold core segments and a second plurality of parallel channels interleaved with the first plurality of channels. The second plurality of channels receives a like plurality of intermediate members which, in turn, receive a like plurality of second mold core segments. The plurality of first mold segments withdraws from the mold and the plurality of second mold segments, which are constrained to move generally radially within the mold collapse radially inwardly to facilitate removal of the molded part.
