发明名称 DIE FOR TIRE MOLDING
摘要 PROBLEM TO BE SOLVED: To provide a die for tire molding, in which a bent piece is hardly deformed when hammering the bent piece to a lower hole.SOLUTION: A lower hole 22 comprises a large diameter part 221 which has a large diameter on an inside part of a die body 2, and a small diameter part 222 which has a small diameter relative to the diameter of the large diameter part 221 on an outside part of the die body, and comprises a step 223 on a boundary between the large diameter part 221 and the small diameter part 222. A bent piece 3 has hardness higher than that of the part where the lower hole 22 of the die body 2 is formed, and has a taper part 32 whose diameter becomes smaller as going to outside on the die body 2, on a position that matches to the step 223 when the bent piece is embedded in the lower hole 22.SELECTED DRAWING: Figure 3
