Embodiment 1

[0039] As shown in Fig. 1, Fig. 2, Fig. 10 and Fig. 11, the present embodiment is a kind of tire vulcanization active mold that the vulcanizer of manufacturing large engineering vehicle tire is integrated with mold, and it comprises loam cake 19, support 21, center There is a locking device between the mechanism 32, the upper side plate 1, the lower side plate 2, 18 pattern blocks 3, the middle mold cover 4, a driving device of the middle mold cover 4, and the upper cover 19 and the support 21.

[0040] The middle mold cover 4 is installed in the machine base 21, and a driving device of the middle mold cover 4 adopts a hydraulic cylinder composed of the lower part of the middle mold cover 4 and the bottom of the machine base 21. The cylinder barrel of the cylinder, the bottom 41 of the middle mold cover 4 is used as the piston of the hydraulic cylinder. The hydraulic cylinder is a plunger cylinder, and there is a first sealing ring 38 and a second sealing ring 39 between the i...

Embodiment 2

[0053] As shown in Figures 6 to 11, this embodiment is also a tire vulcanization active mold that integrates a vulcanizer and mold for manufacturing large-scale engineering vehicle tires. It includes an upper cover 19, a machine base 21, a central mechanism 32, and an upper side plate 1. Lower side plate 2, supporting plate 28, 24 pattern blocks 3, middle mold cover 4, a drive device for middle mold cover 4, and a locking device between the upper cover 19 and the machine base 21.

[0054] In the mold closing state, the upper surface of the supporting plate 28 is in contact with the lower surface of the lower side plate 2 , and the lower surface of the supporting plate 28 is in contact with the bottom surface of the middle mold case 4 . The supporting plate 28 has a cavity 40 for passing through the heating medium, and the lower side plate 2 has no cavity 40, which is different from the first embodiment.

[0055] The lower part of each pattern block 3 has a hinge 5 , and the 24...

Abstract

The present invention relates to a tyre vulcanization activating mould used for integrating the vulcanizing machine and the mould, namely, a tyre vulcanization mould, aiming to solve the technical problem that the prior tyre vulcanization activating mould does not realize the integration with the vulcanizing machine, thereby having a high cost of manufacture of the whole tyre vulcanization equipment. The present invention adopts the technic proposal as follows: the tyre vulcanization mould comprises an upper cover 19 with an upper side plate 1, a lower side plate 2, a plurality of pattern blocks 3, a middle mould sleeve 4 and a bedplate 21; the lower side plate 2 and the pattern blocks 3 are arranged in the middle mould sleeve 4 which is arranged in the bedplate 21; the middle mould sleeve 4 is provided with a driving locking device which is capable of driving the middle mould sleeve 4 to move along the axes L direction of the mould, and a locking device is arranged between the upper cover 19 and the bedplate 21. The present invention is capable of saving the vulcanizing machine, and realizes the integration of the vulcanizing machine and the mould, thereby saving the global cost of making the tyre equipment and simplifying the fabrication technology of the tyre.

Description

Technical field: [0001] The invention relates to a tire vulcanization mold, in particular to a tire vulcanization active mold which integrates a vulcanizer and a mold. Background technique: [0002] Tire molds can generally be divided into two types, one is a two-half mold, and the other is a flexible mold. [0003] The basic configuration of the two-half mold is that it is divided into upper and lower halves from a plane passing through the centerline of the tread pattern around the circumference of the tire. Due to the simple structure, the mold has the advantages of low processing and manufacturing costs. However, for radial tires and tires with deep patterns on the outer tread, it is very difficult to make demoulding using this mold. Therefore, to manufacture radial tires and tires with deep patterns on the outer tread, active molds are generally used. [0004] The traditional movable mold mainly includes an upper side plate, an upper cover plate, a lower side plate, ...
