ABSTRACT:
This disclosure relates to a mold ejecting apparatus for ejecting an inner mold from a cylindrical molding, e.g. a cylindrical rubber molding, sticking to the outer circumference of the inner mold, or for ejecting the cylindrical rubber molding from the inner mold. A plurality of small holes are formed through the circumferential wall of the inner mold, and a pressurized fluid feed line is connected to an opening in one end face of the inner mold to introduce a pressurized fluid into the hollow interior of the inner mold. A plurality of matching members are movable to contact or come close to the outer circumference of the inner mold and match with an end face of the molding, the matching members being movable towards and away from the outer circumference of the inner mold. A pressing apparatus is provided for moving the molding relative to the matching members and the inner mold and separating them.
