Description

Technical Field

[0001] The invention relates to the technical field of tire pre-vulcanization active molds, in particular to a ring-shaped tread vulcanizer. Background Art

[0002] At present, most countries in the world mainly produce strip treads in tire tread production, and the market share of strip treads far exceeds that of other forms of treads. With the emergence of new tire production processes and the advancement of production technology, the market share of toroidal treads is also gradually increasing, and the toroidal tread vulcanizers closely related to toroidal tread production are also constantly upgraded.

[0003] The toroidal tread vulcanizer is a mechanical device used to produce toroidal tire treads. Its main core structure is a multi-piece internal and external flexible mold pressing mechanism. In the actual working process, the internal and external molds are buckled together by external force, and then the molds are pressurized and heated to achieve the vulcanization of the toroidal tire tread inside and outside the molds.

[0004] Chinese patent CN200810139756.9 relates to an upper annular tread forming machine and method thereof, providing an integral forming machine equipment and a process method using mechanical tread expansion, set and press. A mechanism and method for uniform radial expansion of an annular tread is realized, the accuracy of coaxial set of annular tread and carcass is improved, and the phenomenon of tread deviation is avoided. The upper annular tread forming machine mainly includes a main machine, a slide, a clamping ring, an expansion ring and a combined pressure roller. The main machine has a closed main machine box and a bottom plate; at least two sets of main shaft assemblies are arranged inside the main machine box, and a circular rim for carrying the carcass is sleeved on the outer end of each main shaft assembly; a plurality of support rods distributed along the circumference and axially connected are arranged on one side of the vertical part of the expansion ring body of the expansion ring, and a driving part connected and driving the support rod to move radially to support the annular tread is arranged on the other side of the vertical part of the expansion ring body; the combined pressure roller includes a split and combined pressure roller for rolling the crown to the sidewall and a multi-piece pressure roller for rolling the tread. CN110065183A discloses a ring-shaped tread active mold, which includes a guide device, an inner movable device, and an outer support device from the inside to the outside, wherein the lower part of the outer support device is connected with a bottom plate, the guide device is connected with the inner movable device, the guide device can move up and down in the vertical direction, and the inner movable device can move along the radial direction of the horizontal circular surface under the action of the guide device; when the guide device as a whole moves upward to the highest position in the vertical direction, the inner movable device can correspondingly move toward the center position of the ring-shaped tread active mold along the horizontal plane; when the inner movable device moves downward to the lowest position in the vertical direction under the guidance of the guide device as a whole, the inner movable device can move outward, and the outer support device can clamp the inner movable device; the present invention solves the shortcomings of the prior art that the pre-vulcanized active mold structure is relatively complex, requires a lot of screw and bolt structures, is not easy to disassemble, and a simple mold cannot open and close the mold at one time, and has good operability. The oblique cylindrical surface 71 is slidably connected with the support 1, and the support (1) is a "T"-shaped body. CN200920118813.5 relates to a vulcanization mold for replacing the tread of an old tire, specifically a ring-shaped tread vulcanization mold, comprising a base plate and a cover plate, between which are arranged from inside to outside an upper and lower middle mold, a cavity, a pattern block, a slider, a guide strip, a mold sleeve with a steam chamber and a steam chamber cover plate, a matching guide strip is arranged between the slider and the mold sleeve, a limiting slide groove is arranged on the inclined plane of the guide strip close to the mold sleeve, a limiting bolt is installed on the mold sleeve and presses against the limiting slide groove, the guide strip is in a "convex" shape, evenly installed on the inner wall of the mold sleeve and corresponding to each pattern block, wear-reducing plates are arranged on both sides of the guide strip, an adjusting ring is arranged on the outside of the cover plate, and a high-pressure steam inlet hole and a high-pressure steam exhaust hole communicated with the steam chamber are provided on the steam chamber cover plate. The mold has the advantages of reasonable structure, convenient vulcanization and guaranteed tire quality.However, in the prior art, the length of the tread to be bonded must be determined according to the tire circumference and the tread expansion ratio during the bonding process, and the tread cut to a fixed length must be stretched and bonded during the bonding process, which can easily lead to uneven stretching during the bonding process. In addition, there is an interface after the strip tread is bonded, and the tread pattern often cannot be aligned, so it is not smooth and beautiful. Most tread vulcanizers are vertical vulcanizers, and there are also fewer vertical annular tread vulcanizers. It is very cumbersome for the vertical vulcanizer to load and unload the tread mechanically or manually, and there are safety issues. Summary of the invention
