Abstract

본 발명은 타이어의 사이드웰과 트래드용 가변형 압출기다이에 관한 것으로, 일정한 폭(D), 두께(t), 두께(t)방향으로의 각도 B가 만족되지는 세그먼트로 구성되어진 가변형 압출기다이 역시 사이드웰과 트래드의 재질인 고무의 유입부와 배출부 사이의 각도 A가 만족되게 이루어져 사이드웰과 트래드의 반제품이 생산되는데, 상기 가변형 압출기다이로 인해 새로운 다이의 제작에 드는 시간과 재료비가 절감되고, 타이어의 트래드 및 사이드웰용 고무가 압출될 때 각부분의 위치를 용이하게 변경시킬 수 있어 다이의 교체시간이 감소되어지도록 된 것이다(선택도 제1도).The present invention relates to a tire sidewell and a tread variable extruder die, and a variable extruder die composed of segments whose angles B in a constant width (D), thickness (t) and thickness (t) directions are also satisfied. The angle A between the inlet and the outlet of the rubber, which is a material of the well and the tread, is satisfied to produce a semi-finished product of the sidewell and the tread. When the rubber for the tread and the side well of the tire is extruded, the position of each part can be easily changed so that the replacement time of the die is reduced (selectivity 1).
