Technical Field

[0001] This utility model relates to the field of tire mold technology, and in particular to a tire mold with a circulating cooling structure. Background Technology

[0002] Tire molds are key equipment in the tire manufacturing process, mainly used to transform raw rubber into finished tires with specific patterns, structures, and performance through vulcanization. Their core functions include vulcanization and molding. Tire molds can be divided into two categories based on their structure: movable molds, which consist of tread rings, mold sleeves, upper and lower side plates, etc. These are technically complex and suitable for high-precision tires. Sub-types include conical guide and inclined plane guide movable molds. Two-part molds, consisting of an upper mold and a lower mold, have a simple structure and are easy to maintain. They are mostly used for tires with simpler tread patterns, such as engineering tires. Based on their application, tire molds can also be divided into tread molds, sidewall molds, tire base molds, and complete sets of molds. Downstream applications include automobiles, construction machinery, and aviation, with radial tires being the mainstream product.

[0003] When workers need to process tires, they place raw rubber on the second mold, and the first mold is placed on the raw rubber and abuts against the second mold so that the tire mold can process the tire. However, existing tire molds may overheat during use, causing thermal fatigue and reducing the service life of the tire molds. Utility Model Content

[0025] In this embodiment, the sealing cover 42 can be used in conjunction with the cooling pool 31 to achieve the purpose of sealing the cooling pool 31.

[0026] In this embodiment: a slider 45 is fixedly connected to the inner side of the sealing cover 42, and limit grooves 41 are opened on both sides of the cooling pool 31.
