[0002] As the core tooling for tire vulcanization molding, the surface precision and cavity smoothness of automotive tire molds directly determine the appearance and performance of the finished tire. In the mold processing process, multiple processes such as milling, drilling, and polishing are required. After processing, the mold surface will have residual impurities such as cutting fluid and polishing agent, and the cavity is prone to absorbing moisture. If not thoroughly cleaned, it will lead to defects such as bubbles and insufficient rubber during subsequent tire vulcanization. Therefore, it is necessary to dry and shape the tire in an oven. The sealing of the oven door directly affects the stability of the drying temperature and energy consumption.
[0003] Existing oven door sealing devices have several shortcomings: First, they often use multiple cylinders for independent control, which is complex and costly, making them unsuitable for small ovens; second, some manual clamping devices are laborious to operate, and uneven clamping force can easily lead to hot air leakage; third, they lack a simple positioning structure, making the door prone to shifting when closed, affecting the sealing effect. Therefore, it is necessary to design a door sealing cylinder clamping device for automobile tire mold ovens to solve the above problems. Utility Model Content
