METHOD FOR PRODUCING MOLD FOR STUDDED TIRES, SAID MOLD, AND METHOD FOR PRODUCING STUDDED TIRES

摘要

Provided are a method for producing a mold with which it is possible for individual mold pins to protrude from a tread molding surface with precision and according to design specifications, this mold, and a method for producing studded tires. The bottom sides of flange portions 7 provided partway along the longitudinal direction of individual mold pins 5 is formed as a flat surface 7b perpendicular to the axial direction of the mold pins 5, the axial length between the protruding tips 6b of the mold pins 5 and the flat surfaces 7b is set to a predetermined length L, the peripheral regions of individual pin holes 3 on a tread molding surface 2 are formed into a convex or concave shape with a flat surface 4 perpendicular to the depth direction of the pin holes 3, and the mold pins 5 are inserted into the corresponding pin holes 3 to cause the flat surfaces 7b, 4 to abut one another, thereby protruding on the tread molding surface and producing a mold 1. A studded tire is produced by driving stud pins 15 into installation holes 13 of a base tire BT produced by vulcanizing a green tire GT using this mold 1.
