ABSTRACT:
A plastic molding apparatus which produces the molded part on a centrally located core with this core being elongated and having a non-linear, longitudinal, center axis. The core is removed from the molded part by being pulled directly from the molded part which causes the molded part to assume a temporarily deformed shape with the molded part then springing back into its molded shape after removal of the core.
