Their functions are to support the vehicle body, buffer external impacts, achieve contact with the road surface and provide vehicle driving performance. Tires need to be produced using molds. Most existing molds are integral and cannot be replaced according to different patterns. At the same time, when a part of the mold is damaged, the entire mold body has to be scrapped and cannot be used, which reduces work efficiency, consumes a lot of materials and increases production costs.

[0004] However, during use, the tire is connected and fixed by multiple bolts. During the disassembly and assembly of multiple components, the multiple bolts need to be repeatedly disassembled and assembled, thereby affecting the processing efficiency of the tire. Utility Model Content

[0035] In the description of the present invention, it is necessary to understand that the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0036] Working principle:

[0037] When the combined precision tire mold is used, the upper mold 10 is attached to the surface of the lower mold 9, and the rotating disk 23 drives the gear 24 to rotate, thereby driving the two racks 25 and the moving block 26 to move simultaneously, so that the positioning pin 27 is inserted into the positioning plate 21, and the installation and fixation between the lower mold 9 and the upper mold 10 can be completed. At the same time, the upper mold 10 pushes the connecting column 13 and the push block 14 to move, and the push block 14 pushes the fixing pin 18 to move, so that the fixing pin 18 is inserted into the fixing groove of the lower mold 9, thereby quickly completing the installation and fixation of the moving mold 11;

[0038] The raw materials of the precision tire are injected into the lower mold 9 and the upper mold 10 through the feeding pipe, and the double-axis motor 5 is started to drive the driving shaft 6 and the cam 7 to rotate, thereby pushing the movable plate 2 to move up and down in the support seat 1, and cooperate with the support column 3 and the support spring 4 to drive the lower mold 9 and the upper mold 10 to move, so that the lower mold 9 and the upper mold 10 vibrate, and the bubbles in the tire raw materials are shaken out, thereby improving the processing quality of automobile tires;

[0039] After the tire is cooled and formed, the rotating disk 23 is rotated in the opposite direction to make the two moving blocks 26 move toward each other, the positioning pin 27 is separated from the positioning plate 21, and the upper mold 10 can be removed upwards. At the same time, after the upper mold 10 is removed, the limit spring 20 pushes the limit ring 19 and the fixed pin 18 to move, so that the fixed pin 18 retracts into the moving mold 11, and the moving mold 11 and the tire can be removed upwards.
