Claims

[Claims for Utility Model Registration] An apparatus for extracting and releasing a cylindrical molded product molded from a soft polymeric material and having an undercut and open at both ends from a core mold, the method comprising: extracting the molded product from the core mold; A reciprocating member that moves forward and backward along the axis is disposed on the side, and the reciprocating member has an air nozzle at its center and a plurality of chuck claws each mounted on an air nozzle located radially around the outer periphery of the air nozzle. When the reciprocating member is at the front dead center position, the air nozzle fits between the core mold and the open end of the molded product, and the chuck claw grips the open end of the molded product from the outer periphery. Further, an ejecting ring is fitted on the outer periphery of the air nozzle, and the ejecting ring is configured to eject the molded product fitted to the tip of the air nozzle when the reciprocating member is at the rear dead center position. A mold release device for cylindrical molded products configured as follows.
