[0002] Tires are circular elastic rubber products that roll on the ground and are installed on various vehicles or machines. They are usually installed on metal rims, can support the vehicle body, buffer external impacts, achieve contact with the road surface and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions. They are subjected to various deformations, loads, forces, and high and low temperature effects when driving, so they must have high load-bearing performance, traction performance, and buffering performance. At the same time, they are also required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation. Tire molds are needed in the tire production process.

[0003] At present, during the use of existing automobile tire molds, it is usually necessary to first connect the upper and lower molds, and then fix the upper and lower molds with bolts and anchor bolts before injecting the tire production raw materials into the mold from the injection port to produce the tire. However, when disassembling the mold, it takes a lot of time to use tools to remove all the fixing bolts and anchor bolts before taking the molded tire out of the mold, which is very inconvenient.

When the upper mold 3 completely covers the lower mold 1, the annular protrusion 21 will be embedded in the annular groove 22, thereby improving the sealing effect of the docking point. Then, the rotating rod 16 is rotated counterclockwise by the rotating disk 18, so that the bidirectional screw rod 12 rotates under the action of the engagement of the first bevel gear 15 and the second bevel gear 17. At this time, the two threaded connection blocks 13 threadedly connected to the outer wall of the bidirectional screw rod 12 will move toward each other along the slide groove 19 under the action of the slider 20, so that one end of the limit plug 14 can be inserted into the positioning The slot 8 at one end of the positioning block 7, at this time, the lower mold 1 and the upper mold 3 cannot be separated, and then the tire production raw materials are injected into the mold through the injection port 4. After the automobile tire is formed, the rotating rod 16 is rotated counterclockwise by the rotating disk 18, so that the bidirectional screw rod 12 rotates under the action of the engagement of the first bevel gear 15 and the second bevel gear 17. At this time, the two threaded connection blocks 13 threadedly connected to the outer wall of the bidirectional screw rod 12 will move toward each other along the slide groove 19 under the action of the slider 20, and will also drive one end of the limiting plug block 14 to disengage from the slot 8. Finally, the upper and lower molds can be disassembled by raising the upper mold 3, so that the automobile tire formed in the mold can be taken out more conveniently.
