Description

Technical Field

[0001] The utility model relates to the technical field of tire molds, in particular to a tire mold which is easy to replace. Background Art

[0002] With the continuous development of science and technology, cars have become an indispensable means of transportation in our lives, and the demand for various auto parts is also increasing. Tires are one of the important parts of cars. They are in direct contact with the road surface and work together with the car suspension to alleviate the impact of the car when it is driving. The important role played by tires on cars is increasingly valued by people, and the preparation process is becoming more and more perfect. During the production of existing tires, it is necessary to strictly control the temperature and time of tire vulcanization. If the vulcanization temperature of the tire embryo is not well controlled, the tire will be scrapped and the tire quality pass rate will be affected; if the vulcanization temperature is low, under the same time, undersulfurization will occur. The rubber of the undersulfurized tire will not react fully and the physical properties will be poor. If the undersulfurization is serious, it will become sticky and cannot be used. If the undersulfurization is light, it will affect the wear resistance of the tire, and the wear resistance will be poor, and it will be easily delaminated and damaged; if the vulcanization temperature is high, under the same time pressure, oversulfurization will occur. The rubber of the oversulfurized tire will be brittle, and the wear resistance will also be poor during use, and the phenomenon of chipping and falling will also occur.

[0003] The existing tire molds on the market are generally made by placing semi-finished products into the mold and slowly changing the internal shape through a rubber bulging mold to assist in internal tire molding, so as to avoid mutual adhesion and affect the internal tire molding and subsequent use. However, in actual use, if the mold is opened and directly cooled to room temperature without propping up the processed tire for cooling, the toughness of the tire may be affected. For this reason, we have proposed a tire mold that is easy to replace. Utility Model Content
