Description

Technical Field

[0001] The utility model belongs to the technical field of tire tread molds, and particularly relates to a tire tread mold with independent temperature control for tread blocks at different positions. Background Technique

[0002] Tire tread molds are commonly used auxiliary tools in modern tire production, which can improve the quality and efficiency of tire production. In the process of generating tire treads, according to actual production requirements, different parts of the tire need to be controlled at different temperatures during vulcanization operations. However, most common tire tread molds achieve unified temperature control through a unified temperature control structure, making the temperature of each position roughly the same when the tire tread mold contacts the tire. This leads to over-vulcanization in some parts or insufficient vulcanization in some parts, resulting in problems with the quality of the tire after the tire tread process is completed. There may be problems such as the tread not being formed or the tread being over-formed resulting in pits, etc., which will further lead to the failure of the tire quality to meet the standards. It may be necessary to carry out secondary processing or directly scrap it, which will increase the corresponding production costs and is not conducive to the production and operation of the enterprise.

[0003] In summary, there are some problems in the use of tire tread molds that cannot independently control the temperature of tread blocks at different positions. Therefore, it is hoped to propose a new structure to solve the above technical problems. Summary of the Invention
