Description

Technical Field

[0001] The utility model belongs to the technical field of non-porous tire split molds, and particularly relates to a non-porous tire split mold applicable to the production of different tires. Background Technique

[0002] A non-porous tire split mold is a mold specially designed for manufacturing non-porous tires, and it plays a key role in the tire production process, especially in the tire vulcanization stage. Traditional tire molds usually leave small holes on the tire surface because air inside the mold needs to be discharged during the vulcanization process, and these small holes are exhaust holes. However, the existence of these exhaust holes will affect the appearance quality of the tires and may, to a certain extent, affect the performance of the tires. Most non-porous tire split molds in production can only produce tires of a single model. After changing the tire model to be produced, the entire mold needs to be replaced, which results in a relatively high overall development cost of the mold, and the entire mold occupies a large space, which is not conducive to later maintenance and management, leading to an increase in the overall cost of tire production and affecting the overall competitiveness of the enterprise in the market.

[0003] In summary, there are some problems in the use of non-porous tire split molds that are only applicable to the production of tires of a single model. Therefore, it is hoped to propose a new structure to solve the above technical problems. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a non-porous tire split mold applicable to the production of different tires, and solve the problems raised in the above background technique.

[0005] The utility model is realized through the following technical solutions: A non-porous tire split mold applicable to the production of different tires, comprising: an outer main body of the tire split mold, an inner mold main body, a first fixing bolt, and a second fixing bolt. A mold installation body is provided at the middle position of the internal composition of the outer main body of the tire split mold. An installation inner groove for installing the inner mold main body is opened on the inner side surface of the mold installation body. Six groups of inner mold main bodies are provided on the inner side of the installation inner groove. Outer connecting plates are provided on both left and right side surfaces of the mold installation body. A first connecting threaded hole is opened on the rear side surface of the outer connecting plate. A first fixing bolt for connecting between two groups of outer main bodies of the tire split mold is provided inside the first connecting threaded hole. A second connecting threaded hole is further opened on the outer side surface of the mold installation body. A second fixing bolt for fixing between the outer main body of the tire split mold and the inner mold main body is provided inside the second connecting threaded hole.

[0006] As a preferred embodiment, a tire mold is provided at the middle position of the internal composition of the inner mold main body. A clamping block for facilitating the clamping of two groups of inner mold main bodies is provided on one end side surface of the tire mold. A clamping groove is opened on the other end side surface of the tire mold.

[0007] As a preferred embodiment, the engaging block and the engaging groove are mutually engaged.

A number of pattern blocks are provided on the inner side surface of each tire mold, and they are equally distributed in a circumferential manner. The engaging blocks and the engaging grooves between adjacent two groups of inner mold bodies are mutually engaged, which can facilitate the connection and fixation between adjacent two groups of inner mold bodies.

[0008] As a preferred embodiment, there are two groups of the outer main bodies of the tire split mold, and they are arranged in a symmetric structure. The tire mold is mutually engaged with the installation inner groove, and the rear side surface of the front outer connecting plate is mutually attached to the front side surface of the rear outer connecting plate.

[0009] As a preferred embodiment, connection threaded holes two are also opened at the concentric position of the outer side surface of the tire mold and the connection threaded holes two. The fixing bolts two are screwed into the two groups of connection threaded holes two to fix between the outer main body of the tire split mold and the inner mold body. Screwing the fixing bolts two into the inner sides of the two groups of connection threaded holes two can install and fix between the outer main body of the tire split mold and the inner mold body, and keep the relative positions between the inner mold body and the outer main body of the tire split mold.

[0010] As a preferred embodiment, an air guiding cavity is opened inside the mold installation body. Three air guiding holes two are opened at the middle position of the inner side surface of the mold installation body, and a sealing ring two is provided inside the air guiding holes two.

[0011] As a preferred embodiment, an exhaust pipe is provided above the outer main body of the tire split mold. The exhaust pipe is mutually communicated with the air guiding cavity. An air guiding hole one is opened at the inner side surface of the pattern block at the middle position;

[0012] A sealing ring one is provided outside the air guiding hole one. The air guiding hole one and the air guiding hole two are concentric, and the sealing ring one and the sealing ring two are squeezed and sealed, which can make the internal gas be introduced into the air guiding cavity through the air guiding hole one and the air guiding hole two, and then discharged through the exhaust pipe.

[0013] After adopting the above technical solution, the beneficial effects of the present utility model are as follows: By adding the outer main body of the tire split mold, the inner mold body, the fixing bolt one and the fixing bolt two, placing the inner mold of the inner mold body in the installation inner groove to make the two groups of connection threaded holes two concentric, screwing the fixing bolts two into the inner sides of the connection threaded holes two can connect and fix between the outer main body of the tire split mold and the inner mold body. Placing the two groups of outer main bodies of the tire split mold symmetrically and screwing the fixing bolts one into the connection threaded holes one can be applicable to the production and use of multiple models of tires. By adding the outer main body of the tire split mold and the inner mold body, it can facilitate the discharge of gas. Description of the Drawings
