PROBLEM TO BE SOLVED: To provide a vulcanization mold for tire molding which prevents its one-sided opening from occurring. SOLUTION: This vulcanization mold is split as a top force 2 and a bottom force 4 at split faces 10, 12 which are perpendicular with the axial direction of a tire. In addition, urging members 18 using coned disc springs for urging the split faces 10, 12 uniformly in a direction where the split faces 10, 12 are separated from each other, are installed at an equal interval, on the outer peripheral face of the mold 1. So many pieces of the mold 1 are stacked, in a multi- stage fashion, in a press and tires are vulcanized and molded with these molds 1. |
