PROBLEM TO BE SOLVED: To prevent a collar part 22a from being flawed and being broken during mold releasing of a molded article 21, and in addition to this, to facilitate taking-out work of the molded article 21 after the molded article 21 is ejected, in a mold releasing structure 8 in which the molded article 21 manufactured by vulcanizing and sticking an elastic body 24 made of a rubbery elastic mate rial on an annular rigid part 22 with the collar part 22a is released from a mold 1 for molding. SOLUTION: An ejector ring 11 for pressing the collar part 22a over the whole periphery and ejecting the rigid part 22 from the mold 1 for molding during mold releasing of the molded article 21 is provided in the mold releasing structure 8. In addition to this, the ejector ring 11 is made to be a two-part structure and a structure in which it is held by a taper inlay 12 under a condition before ejecting work. COPYRIGHT: (C)2003,JPO |
