Problems solved by technology

[0002] When the vehicle is running, in order to increase the friction with the road surface, the surface of the tire has various patterns. In order to form the pattern on the surface of the tire, the formed tire is placed in a mold with texture. Under certain conditions Add vulcanizing agent to vulcanize and mold the tire; in the prior art, when using a mold to vulcanize and mold the tire, since most of the vulcanization is under high temperature and high pressure conditions, and the tire is made of rubber, the rubber is mixed with the vulcanizing agent, and a few are burned after high temperature. Coke forms particles, and part of the particles accumulate in the angle between the pattern blocks. Since the particles contain vulcanizing agent, some substances of the vulcanizing agent are corrosive, and the long-term accumulation in the angle between the patterns is easy to cause corrosion on the surface of the mold. , affecting the normal use of the mold, and the desired shape cannot be achieved during the vulcanization process

Embodiment 1

[0027] as attached figure 1 to attach Figure 6 Shown:

[0028] The invention provides a tire mold, the structure of which includes a lower mold 1, an upper mold 2, a vent hole 3, and a guide block 4, the outer wall of the lower mold 1 is movably engaged with the inner wall of the upper mold 2, and the vent hole 3 runs through The outer wall of the upper mold 2, and the guide block 4 is welded on the inner wall of the upper mold 2.

[0029] The lower mold 1 is provided with a feeding port 11, a pattern block 12, and an angle removal device 13. The feeding port 11 is set at the middle position of the lower mold 1, and the pattern block 12 is vertically fixed on the inner wall of the lower mold 1. The clip Corner clearing means 13 are mounted between the blocks 12 .

[0030] Wherein, the included angle clearing device 13 is provided with an air collecting ring a1, a silica gel block a2, an air pipe a3, a piston a4, a support rod a5, a clamping tooth a6, and a clearing ring a7...

Embodiment 2

[0037] as attached Figure 7 To attach Figure 8 Shown:

[0038] Wherein, the roller b1 is provided with a brush block e1, a connecting ring e2, a feeding groove e3, and a collection chamber e4, the brush block e1 is movably engaged with the outer wall of the roller b1 through the connecting ring e2, and the feeding groove e3 is recessed in Between the brush blocks e1, the collection chamber e4 is set inside the roller b1 and communicates with the feed trough e3. There are six brush blocks e1 in total, which is conducive to evenly moving the brush blocks between the pattern blocks 12 when they move horizontally. For the particles collected at the bottom, the connecting ring e2 has elasticity, and the elastic force generated by pressing against the bottom is beneficial to drive the brush block e1 to vibrate slightly, and accelerate the shaking of the particles on the surface of the brush block e1.

[0039] Wherein, the brush block e1 is provided with a wiper block f1, a groov...

Abstract

The invention discloses a tire mold. The tire mold structurally comprises a lower mold, an upper mold, air holes and guide blocks, wherein the outer wall of the lower mold is movably clamped to the inner wall of the upper mold, the air holes run through the outer wall of the upper mold, and the guide blocks are welded to the inner wall of the upper mold. When a tire is vulcanized in a high-temperature environment, an included angle eliminating device is driven to collect burnt particles at included angles between pattern blocks to prevent the situations that the burnt particles accumulate at the included angles between patterns for a long time and corrode the surface of the mold, accordingly the surface is uneven, normal use of the mold is affected, a required shape cannot be achieved in the vulcanization process, and the service life of the mold is shortened. When rollers rotate, brush blocks on the surfaces of the rollers collect the particles scraped by a scraper to prevent the situations that the particles are left on the bottom surfaces of the pattern blocks, slowly accumulate and make the rollers stuck, normal moving of an eliminating ring on the bottom surfaces between the pattern blocks is affected, the particles cannot be collected in time and the corrosion speed of the bottom surfaces is increased.

Description

technical field [0001] The invention belongs to the field of molds, and more specifically relates to a tire mold. Background technique [0002] When the vehicle is running, in order to increase the friction with the road surface, the tire surface has various patterns. In order to form the pattern on the tire surface, the formed tire is placed in a mold with texture. Under certain conditions Add vulcanizing agent to vulcanize and mold tires; in the prior art, when molds are used to vulcanize and mold tires, since most of the vulcanization is under high temperature and high pressure conditions, and the tires are made of rubber, rubber and vulcanizing agent are mixed together, and a few are burned after high temperature. Coke forms particles, and part of the particles accumulate in the angle between the pattern blocks. Since the particles contain vulcanizing agent, some substances of the vulcanizing agent are corrosive, and the long-term accumulation in the angle between the pa...
