TIRE VULCANIZATION MOLD, TIRE PRODUCTION METHOD AND PRODUCTION METHOD OF TIRE VULCANIZATION MOLD

摘要

PROBLEM TO BE SOLVED: To provide a tire vulcanization mold which allows easy equalization of clearances among individual rings in the tire circumferential direction so as to mold the appearance of a side wall part well.SOLUTION: A tire vulcanization mold is provided with side rings 3 having a side wall molding surface 3s for molding of a side wall surface of a tire. The side rings 3 have an annular first ring 6 having a first side wall molding surface 6s and an annular second ring 7 having a second side wall molding surface 7s located on the outer side in the tire radial direction with respect to the first side wall molding surface 6s. The first ring 6 has an inclined outer peripheral surface 63 which is inclined to the tire axial direction and extends from the first side wall molding surface 6s, and the second ring 7 has an inclined inner peripheral surface 73 which is inclined to the tire axial direction and extends from the second side wall molding surface 7s. Centering of the first ring 6 and the second ring 7 is carried out by fitting the inclined outer peripheral surface 63 in the inclined inner peripheral surface 73.
