Embodiment Construction

[0023] Such as Figure 4 to Figure 7 As shown, the present invention discloses a tire curing bladder structure, which is a pair of airbags corresponding to the shape of the inner surface of the tire, the outer surface of which is in contact with the inner surface of the tire. Similarly, in order to better close the mold and avoid the tire crown overflow caused by the capsule, a smooth surface A with no pattern is formed on the outer surface of the capsule corresponding to the tire crown area. The width W1 of the smooth surface A is set to 10mm~25mm, and at the same time The outer surface of the bladder is provided with the tread area B1 corresponding to the tire, the transition area B2 between the tread and the shoulder, the shoulder area B3, and the shoulder and bead area B4. Continuous straight or oblique lines are arranged on these four areas. Line exhaust ditch D, each exhaust ditch D is set in parallel; the height H1 of the exhaust ditch D is set below 0.2mm, and the widt...

Abstract

The invention discloses a tire vulcanization capsule structure which is an air bag corresponding to the shape of the inner surface of a tire. The outer surface of the tire vulcanization capsule structure is contacted with the inner surface of the tire; a pattern-free smooth surface is formed on the outer surface of a capsule, which is opposite to a crown region of the tire; continuous linear or inclined air exhaust trenches which are opposite to a tread region, a transition region between a tread and a tire shoulder, a tire shoulder region and a tire shoulder and bead region of the tire are formed on the outer surface of the capsule and parallel to one another; galalith patterned blocks are distributed among the air exhaust trenches of the tread region, the transition region between the tread and the tire shoulder, the tire shoulder region and the tire shoulder and the bead region of the tire on the outer surface of the capsule; and each galalith patterned block is formed by encircling three or more trenches which are not positioned on the same straight line. Due to the galalith patterned blocks, the number of air exhaust channels on the surface of the capsule is increased greatly, the air exhaust performance is improved, and the problem of low moisture in the tire is solved effectively; and the service life of the tire vulcanization capsule is prolonged.

Description

technical field [0001] The invention relates to a tire curing bladder, in particular to a tire curing bladder structure. Background technique [0002] Known general tires are vulcanized with water tires and bladders. Now more and more tires are vulcanized with bladders, and the overall design requirements for the surface pattern of the vulcanized bladders are getting higher and higher. At present, the surface of domestically produced tire curing bladders is only composed of exhaust grooves. When this type of bladder is vulcanizing tires, due to the lack of exhaust channels, the contact area between the surface of the bladder and the inner surface of the tire is relatively large, and the exhaust performance is poor. Tires are prone to poor moisture inside. [0003] like figure 1 , 2 As shown in 3, in the tire curing bladder of the previous example, in order to better close the mold and avoid the crown overflow of the bladder, there is no pattern setting in the crown area, ...
