Problems solved by technology

If the depth of the exhaust line is designed to be large, it is easy to cause too much rubber to enter the outline of the exhaust line, resulting in unnecessary waste of rubber, and the phenomenon of mucous membranes on the inside of the tire. At the same time, the rubber in the raised part of the exhaust line is uneven. It may even expose the surrounding carcass ply, causing problems in appearance and safety

Abstract

The invention discloses an airbag bag mold for tire vulcanization. The texture depth of the airbag bag mold for tire vulcanization is 0.1-0.2 mm. The airbag bag mold for tire vulcanization can adjust the texture and exhaust line depths under the precondition of guaranteeing the tire air keeping performances, so that rubbers are reasonably applied, the cost is controlled, the beauty of inner side textures is facilitated, and meanwhile, the bad phenomenon in tires is reduced.

Description

technical field [0001] The invention relates to the technical field of tire production, in particular to an air bag mold for tire vulcanization. Background technique [0002] The tire vulcanization process refers to the process of vulcanizing the outer tire by pressurizing the model. During the vulcanization process, the tire blank is filled with airbags and injected with high-pressure and high-temperature steam, and the expansion pressure of the airbag bag is used to fill the tire blank with the model. Vulcanization is mainly a chemical reaction inside the rubber semi-finished product under a certain temperature and pressure, so that the linear rubber macromolecules can be transformed into a network or body structure through a cross-linking reaction to obtain the required mechanical properties. [0003] Therefore, how to design a mold to manufacture a vulcanized air bag is directly related to the performance of the finished tire, especially the air retention performance. ...
