    Abstract: A part removal tool for removing a resilient molded tubular part from a mold core first clamps the molded part on a cup removal tool at one end of the part and then inflates the part to separate the part from a mold core. The part removal tool includes a protective housing having spaced protective side plates that protect interior switches, conduits and actuators, while providing easy connections with exterior quick release fittings. The tool employs replaceable clamps and part removal cups so that the tool can be used for a variety of parts of different sizes and shapes.
