Abstract
PURPOSE: To improve the molding precision of a diameter-expanded accepting mouth and to mold easily the accepting mouth capable of maintaining stably a ring packing by a method wherein an outer mold for the outer circumference of a circular groove part is conposed of a forming mold having a specific inner diameter and a moving outer mold on the open side of the accepting mouth.
CONSTITUTION: The inner diameter of a forming mold 9 is made slightly smaller than the diameter of the molded surface on the outer periphery of a circular groove part of the moving outer mold 10 on the open side of the accepting mouth and when a sliding core mold 7 is moved outside, the forming mold 9 is let to slide on the outer periphery of the circular groove part which has been returned to the original state and adjusts it. When the molding surface 9b is placed on the expanded part 3a, the molding surfaces 9c, 9b press and shape the top surface of the expanded part 3a, the shaped part is cured precisely, the shape of the inner peripheral surface 3b of the open mouth part is adjusted securely and the diameter of the inner peripheral of the bottom of the circular groove 3 can be molded precisely.
