PURPOSE: To automate a process releasing a hollow rubber molded product having axial release resistance with respect to a core mold. CONSTITUTION: An air nozzle 17 and a cylindrical body 18 both of which are axially movable up and down are provided and the lower end part 17b of the air nozzle 17 is brought into close contact with the inner peripheral edge of the upper end opening part 1a of the rubber molded product 1 clinging to the outside surface of a core mold 2 and the cylindrical body 18 is arranged on the outer peripheral side of the rubber molded product 1 and air is supplied from the air nozzle 17 to expand the rubber molded product 1. By this constitution, the upper end opening part 1a of the rubber molded product is fitted to the large diameter side of the air nozzle 17 in a close contact state and the side peripheral wall 1c of the rubber molded product 1 is brought into close contact with the inside surface of the outer cylindrical body 18 under pressure and the air nozzle 17 and the cylindrical body 18 are raised to draw out the rubber molded product 1 from the core mold 2. |
