Description

technical field

[0001] The invention relates to the technical field of tire production devices, in particular to a die plate with adjustable outlet size. Background technique

[0002] Tires are circular elastic rubber products that are rolled on the ground and rolled on various vehicles or machinery. Usually installed on metal rims, it can support the body, buffer external impact, realize contact with the road surface and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions, and they are subjected to various deformations, loads, forces, and high and low temperature effects during driving, so they must have high load-bearing performance, traction performance, and cushioning performance. At the same time, it is also required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation. The tread is an important component of the tire. The tread extrusion pressure die plate includes a ...
