<P>PROBLEM TO BE SOLVED: To provide a vulcanizing mold for a tire having, on an inner surface of a segment mold, a pin for molding a spike pin hole, wherein load applied to the spike pin hole when a pin at a circumferentially end part of the segment mold comes off from the spike pin hole is reduced when opening the mold. <P>SOLUTION: The vulcanizing mold for a spike tire has the mold pin 9 for the spike pin hole on the inner surface of the segment mold 1. The mold pin 9 is composed of: a rod part 91 embedded in an inside of an inner surface of the segment mold 1; an axis part 92 protruded from the inner surface of the segment mold 1; and a coil spring 94 connecting them. The coil spring 94 pulls the axis part 92 upon radial movement of the segment mold 1 when opening the mold. Thus, the axis part 92 follows the spike pin hole, thereby coming away without being subjected to resistance from the spike pin hole. <P>COPYRIGHT: (C)2012,JPO&INPIT |
