Abstract

본 발명은 타이어제조시 그린타이어의 가류공정시 가류금형 내부에 있는 공기 및 가스를 자연 유도하여 외기로 배출시키는 타이어 가류금형의 공기배출구조와 이의 방법에 관한 것으로, 그린타이어(1)의 트래드(2)에 접촉하는 상·하부금형(3,4)의 내부원주방향은 일정한 등각도로 분할하고, 각 분할편들(S1-S8)의 긴반경(R1)과 짧은반경(R2)은 다음과 같은 관계식을 갖도록 형성되어 있다.The present invention relates to an air discharge structure of a tire vulcanization mold and a method thereof, which naturally induces air and gas inside the vulcanization mold during the vulcanization process of the green tire during tire manufacture and discharges it to the outside. 2) The inner circumferential direction of the upper and lower molds (3, 4) in contact with each other is divided into constant equal angles, and the long radius (R 1 ) and the short radius (R 2 ) of each of the divided pieces (S 1 -S 8 ). Is formed to have the following relationship.
