PROBLEM TO BE SOLVED: To provide a tire vulcanizing mold capable of taking out a molded tire in a stable state without damaging or deforming the same at the time of takeout. SOLUTION: The stroke lengths of the respective sectors of bisected mold main bodies 1 and 2 are set as follows by adjusting the projecting pressures of the projection means 4 respectively provided to the bisected mold main bodies 1 and 2. That is when the tire W after vulcanizing molding is taken out of the bisected mold main bodies 1 and 2, the stroke lengths in the tire diametric direction Y-Y of the respective sectors 3 of the bisected mold main bodies 1 and 2 are constituted so as to form a relation of (L1)>(G)>(L2) in a case that the stroke length of the sector on a preceding demolding side is set to (L1), the stroke length of the sector on a later demolding side is set to (L2) and the maximum depth of the tire formed to each of the sectors 3 is set to (G). Further, a relation of (L2) and (G) is set so as to become (0.8G)≥(L2)≥(0.4G). COPYRIGHT: (C)2007,JPO&INPIT |
