[0002] Vulcanization reaction refers to connecting one or more sulfur atoms to the polymer chain to form a bridge structure, and the result of vulcanization reaction is to generate elastomers that change performance in many aspects; The meaning of "vulcanization" not only includes the process of actual crosslinking, but also includes the method of producing crosslinking. In the production process of tires, the tire blank needs to be placed in the mold for vulcanization forming, and with the continuous development of tire industry, tire vulcanization machine technology is also continuously improving. According to the Chinese patent document with the announcement number CN221540726U, a tire vulcanization device is disclosed, the upper end face of the workbench is rotatably connected with a fixed column, the outer wall of the fixed column is fixedly connected with a support rod, the lower end face of the support rod is slidably connected with a first air cylinder, the end of the first air cylinder away from the support rod is fixedly connected with a fixed block, the fixed block is fixedly connected with a first reversible motor, the output end of the first reversible motor is connected with a rotating shaft, the outer wall of the rotating shaft is fixedly connected with a rotating disc, a plurality of arc-shaped limiting grooves are formed in the rotating disc, the arc-shaped limiting grooves are evenly distributed around the axis of the rotating disc, a fixed disc is hingedly connected to the upper end face of the rotating disc, a plurality of slide rods and arc-shaped blocks can move towards the outer diameter direction of the fixed disc, which can well take out different sizes of tires, improve the flexibility of the tire vulcanization device, realize fast material taking and discharging, reduce the labor intensity of workers, and improve the working efficiency of the tire vulcanization device. However, the technology still has the following disadvantages: 1. The tire is not fixed during vulcanization, and the tire is prone to deformation under high temperature; 2.
