[0002] The steps of tire forming mainly include the following aspects: 1. mixing: mixing natural rubber or synthetic rubber with a series of additives, such as auxiliary agents, fillers, oils, vulcanizing agents, etc., to prepare rubber composites; 2. calendering: calendering the mixed rubber composites into strips with a certain width and length; 3. forming: pressing the calendered rubber strips into the precursor of the tire through a mold to form the pattern and structure of the tire; 4. vulcanization: performing vulcanization reaction under high temperature and high pressure to stabilize and strengthen the rubber material in chemical and physical properties, and at the same time to make the tire have the performance of assembly and use; 5. cutting and trimming: trimming the vulcanized tire into the final size and shape to meet the design requirements, quality standards and safety requirements; 6. quality inspection, packaging: quality inspection, screening, classification, packaging, labeling, etc. of the tire to ensure the quality and use effect of the tire.

[0003] At present, during the tire forming process in the mold, the inner side of the mold is provided with a pattern, and after the green tire is tightly attached to the pattern, the forming of the tire surface pattern is completed.

The air retained between the mold and the green tire will cause the formation of concave pits on the outer surface of the tire and other forming defects. After the green tire is formed, the surface temperature of the tire is high, which is not conducive to the handling of the formed tire. SUMMARY

[0051] In the application, when the tire is molded, first, the tire body is sleeved on the capsule 3, then the hydraulic push rod 6 and the air pump 801 are started, and the positioning and semi-molding of the tire are realized. After the hydraulic push rod 6 is started, the top plate 4 and the pressing plate 5 are lowered, the pressing plate 5 presses the tire on the top of the bottom plate 2, the air pump 801 inflates the air cavity 7 through the air inlet pipe 802, the gas is injected into the capsule 3 through the air hole 9 on the air cavity 7, and the capsule 3 is inflated due to the action of the air pressure. Then the capsule 3 is tightly attached to the inner side of the tire blank, and the tire is preliminarily molded, the positioning and semi-molding of the tire are realized, and the tire blank is fixed. After the air cylinder 152 is started, the assembly of the mold 11 used for the tire is realized.

The inclined surface of the trapezoidal block 14 is pressed, and the mold 11 is offset after being pressed. At this time, all the molds 11 are close to the center of the tire, until the adjacent two molds 11 are tightly attached to each other. A plurality of molds 11 form a complete closed loop, and the assembly of the mold 11 is realized. After the mold 11 is assembled, the outer side of the tire is in contact with the tread 12 on the mold 11. At this time, the air pump 801 is started, and the tread of the tire is molded. With the working of the air pump 801, the capsule 3 is inflated, the capsule 3 pushes the tire to embed into the tread 12, and the molding of the tread of the tire is realized. During the process of molding the tread of the tire, the air between the tire and the mold 11 is discharged from the mold 11 and the tire. Since the demolding plate 21 is protrudingly arranged, the tire in contact with the demolding plate 21 is not in contact with the tread 12 on the mold 11.
