Description

Technical Field

[0001] The utility model belongs to the technical field of tire pattern molds, and particularly relates to a tire pattern mold which reduces the generation of rubber edges at the butt joint of steel sheets. Background Art

[0002] Tire pattern production is an indispensable part of the modern tire manufacturing process. The main function of the tire pattern is to enhance the friction between the tread and the road surface, thereby preventing the wheel from slipping. In modern production, most tire pattern molds are used to generate tire patterns. However, when two sets of molds are docked, the gap at the joint of the steel sheets often causes the tire to have rubber edges after the pattern is generated. The common treatment method in production is to specifically remove the rubber edges after the tire pattern is generated, and set up a corresponding rubber edge removal process to ensure that the rubber edges are removed before leaving the factory, reducing customer complaints about quality due to rubber edge problems, as well as problems in subsequent use by users. However, the setting of the rubber edge removal process will increase the corresponding cost investment in production, and various equipment, labor, etc. need to be spent, and corresponding supervision is required, which will lead to the complexity of production. In modern production, it will reduce its comprehensive competitiveness and is not conducive to the development of the enterprise.
