Problems solved by technology

However, during the use of the mold, the gap between the guide ring and the protrusion of the base will become larger due to the reduction of the matching accuracy, which will reduce the sealing effect of the base and the guide ring, resulting in the vacuum degree inside the mold not meeting the use requirements.
[0005] In addition, the frequent opening and closing of the mold will cause the wear of the sealing ring, resulting in a low service life of the sealing ring

Embodiment 1

[0041] Embodiment 1 Vacuum tire flexible mold

[0042] Such as Figure 1-3 As shown, the present invention provides a vacuum tire active mold, including upper side plate 12, lower side plate 2, pattern block 3, slider 4, guide bar 6, upper slider 10, guide ring 7, limit block 5 , Loam cake 11, base 1, mounting ring 8, upper sealing ring 9.

[0043] A sealing groove is arranged on the upper end surface of the base 1, and a sealing ring 18 is arranged in the sealing groove, and the sealing ring 18 cooperates with the lower end surface of the guide ring 7 to realize the end face sealing between the lower end surface of the guide ring 7 and the upper end surface of the base 1. A groove is preferably arranged on the upper end surface of the base 1, and the sealing groove is arranged in the groove.

[0044] The structure of the sealing ring 18 is preferably a trapezoidal cross section, or a semicircle, or a square, or a triangle. The bottom of the sealing ring 18 is preferably pr...

Embodiment 2

[0052] Embodiment 2 Vacuum tire flexible mold

[0053] Such as Figure 4-6As shown, the present invention also provides a kind of vacuum tire flexible mould, and the difference with embodiment 1 is: also can adopt Figure 6 The sealing structure in is: the structure of the sealing ring 18 is preferably a semicircle in its cross section. The bottom of the sealing ring 18 is preferably provided with a groove 19, and the shape of the groove 19 is an inverted semicircular groove.

[0054] The upper cover 11 and the mounting ring 8 are provided with an upper sealing ring 9 and a sealing flange 13, and the mounting ring 8 and the outer circle of the mounting ring 8 and the guide ring 7 are provided with a sealing disc 14. Wherein the connecting bolts of the mounting ring 8 and the guide ring 7 can be covered by the sealing disc 14 , and can also be covered by the upper sealing ring 9 .

[0055] Wherein the sealing disc 14 is arranged outside the outer circular surface of the moun...

Abstract

The invention discloses a vacuum pumping tire segmental mold. The segmental mold comprises a base and a guide ring; a seal device is arranged between the lower end face of the guide ring and the upper end face of the base; the mold has the beneficial effects that exhaust is smooth, the dead corners of the mold are easily filled with tire compounds, the tire appearance is attractive, and the tire performance is good; the position between the guide ring and a mounting ring is subject to end face fixed seal, the seal effect is better, the service life of a seal ring is prolonged, and the material cost is reduced; the mold can be used by mounting rings in different shapes and with different types, and the adaptation is wide; meanwhile, components of the segmental mold are convenient to machine, the difficulty is low, the phenomenon that due to grooving in the guide ring, the strength is reduced is avoided, in addition, the phenomenon that a seal ring is placed on the lower end face of the guide ring, when the guide ring is placed and transported, the seal ring needs to be protected against damage caused by extrusion or collision is avoided, cost for machining and designing a new mold again is saved, a vacuum pumping mold of a new structure does not need to be designed again, the mold can be sealed, and the design and machining cost of the vacuum pumping mold is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of tire moulds, and relates to a vacuum tire flexible mold, especially for vacuum tire flexible molds with high tire pattern appearance and relatively complex patterns, which can be widely used in passenger tires, light truck tires, truck tires, engineering tires , Giant tire active mold. Background technique [0002] At present, the application of radial tires is getting wider and wider, and the competition is also intensifying. Tires with beautiful appearance and strong practicability are more and more favored by people. In particular, high-end tires with complex patterns are favored by car owners, and the more complex the tread pattern, the easier it is for the mold to have poor exhaust during the tire building process, resulting in lack of rubber in the tire and affecting the appearance of the tire. [0003] In order to discharge the gas smoothly, the traditional active mold processes a large number of ...
