Embodiment 1

[0029] Such as figure 2 As shown, 1 is the middle mold cover, 3 is the upper side plate, 4 is the slider, 5 is the lower side plate, 6 is the anti-friction block, 2 is the pattern block, which is located between the upper side plate 3 and the lower side plate 5 A tire crown pattern is formed, pattern blocks 2 are evenly distributed on the same circumference, and a slide block 4 is fixed at the bottom thereof. The inclined surface of the outer surface of the pattern block 2 and the inclined surface of the inner surface of the middle mold sleeve 1 are relatively matched and slid, and the pattern block 2 and the lower side plate 5 are positioned and connected in the axial direction of the mold, and there is no axial displacement between them. 1. During the mold closing process, each pattern block can simultaneously reciprocate synchronously on the upper part of the lower side plate 5 along the radial direction of the mold. Plate 3 moves up and down. A plurality of pattern bloc...

Embodiment 2

[0035] The connection mode between the pattern block 2 and the lower side plate 5 in the axial direction of the mold is as follows: Figure 4 As shown, the protrusion at the bottom of the pattern block 2 and the pattern block 2 form an integral structure. The groove is combined with two friction-reducing blocks 6 fixedly installed along the radial edge of the groove.

[0036] Others are the same as embodiment 1.

Embodiment 3

[0038] The connection mode between the pattern block 2 and the lower side plate 5 in the axial direction of the mold is as follows: Figure 5 As shown, the protrusion at the bottom of the pattern block 2 is integrated with the pattern block 2, and the section of the protrusion is dovetail-shaped, and the groove on the upper part of the lower side plate 5 is also a corresponding dovetail groove.

[0039] Others are the same as embodiment 1.

Abstract

The present invention relates to a vulcanized radial tire mould. It includes the following several portions: upper side plate, middle mould cover, lower side plate and tread block positioned between upper side plate and lower side plate for forming tire tread face. Said the mould is simple, can greatly reduce tire cost.

Description

technical field [0001] The invention relates to molds, in particular to a mold for vulcanizing radial tires. Background technique [0002] Existing tire molds such as figure 1 As shown, a plurality of tile-shaped pattern blocks 5 are evenly distributed on the same circumference, and form a circumferentially closed pattern circle after being closed. The pattern blocks 5 are fixed on the bow seat 3 in one-to-one correspondence; the outer surface of the bow seat 3 is a conical surface or an inclined plane, and the inner surface of the middle mold cover 1 and the outer surface of the bow seat 3 cooperate and slide relative to each other. Each conical surface or inclined plane on the outside of the bow-shaped seat 3 is vertically fixed with a "T"-shaped guide strip 2, and each "T"-shaped guide strip is in the corresponding "T"-shaped groove on the inner surface of the middle die sleeve 1 slide. The slide block 4 fixed on the top of the arc seat 3 is positioned and connected wi...
