Problems solved by technology

[0002] In the production of tires, especially in the production of tire surface pattern forming and processing, it is necessary to use various types of tread ring molds for production, and the tread ring molds used in the purpose are generally composed of shells, tread rings and side plates. Partial assembly, in the current assembly process, due to the lack of fine requirements for the important connecting parts of the shell, pattern ring and side plate and the corresponding professional assembly process, it has led to the current process of pattern ring mold During assembly, various assembly methods are used, and there are often large cumulative tolerances during assembly due to excessive processing errors of the important connecting parts of the shell, pattern ring and side plate, resulting in the shell, pattern ring and side plate. When the side plate is connected, there is a large position deviation, which leads to the disadvantages of failure to connect or excessive gap between the contact surfaces after connection. In order to overcome these disadvantages, the current common practice is to use external force to adjust the position of each connecting part, or Adding gaskets in the gap of the connecting surface, on the one hand, caused the extremely poor accuracy of the pattern ring mold, on the other hand, it also caused great damage to the structure of the pattern ring mold, greatly reducing the service life of the pattern ring mold

Abstract

The invention discloses an assembling process of a pattern ring and a side plate of a tire mold. The process comprises the steps of molding through the mold and processing, finely processing the rough connecting surface of the mold, and then assembling the mold, wherein the mold is specially assembled by the method of combining uniform heating interference fit and bolt-based connection. According to the assembling process of the pattern ring and the side plate of the tire mold, the production process adopted is able to effectively raise the assembling precision of a tire pattern ring mold and the connecting quality of each connection surface after assembling, and thus the production quality of tires is improved; in addition, the phenomenon that the mold is easily damaged during assembling can be effectively avoided, and as a result, the service life of the mold can be effectively prolonged, and the repeated utilization rate of the mold is also effectively raised.
