Abstract
The utility model provides a tire curing bladder, including the capsule body that corresponds green tire internal surface shape, the child lateral part that the capsule body corresponds green tire is no pattern portion, the inside cavity that is of capsule body, this internal cavity week along its inner chamber of capsule be equipped with honeycomb, this honeycomb comprises a plurality of protruding groove combinations, and protruding groove is towards the inside protruding setting of capsule body. The utility model has the advantages that: the honeycomb structure arranged in the capsule body prevents the phenomenon that the interface hard force is concentrated and the capsule is damaged in the early stage because the tension difference between the part where the honeycomb structure is located and the non-pattern part is large; and the air holes arranged on the inner side of the capsule body play a role in heat dissipation and ventilation.
Description
Technical Field
The utility model belongs to the technical field of the rubber and plastic goods, in particular to tire curing bladder.
Background
A curing bladder (curing bladder) is a hollow thin-wall rubber product of a tire vulcanizer and is used for filling an inner cavity of a tire blank to be vulcanized and then introducing a heating medium to be matched with the vulcanizer to carry out shaping and vulcanizing operation. With the high performance or special functionalization of the tire, the bladder used for tire vulcanization must have different tensions at each part to meet the required performance.
Therefore, only thickness can be relied upon in order to adjust the tension of the various parts of the capsule. When the bladder thickness is increased, a delay in the vulcanization time of the tire is caused, resulting in a decrease in vulcanization productivity, which affects the quality of the tire.
SUMMERY OF THE UTILITY MODEL
The utility model provides a tire vulcanization capsule has both satisfied the characteristics at high tension requirement position, has prevented tire vulcanization time's delay again, especially is fit for being used in vehicle tyre's production.
The technical scheme of the utility model is that: the utility model provides a tire curing bladder, is including the capsule body that corresponds green tire internal surface shape, the position that the capsule body corresponds the side wall of green tire is no pattern portion, capsule body inside be the cavity, the capsule body in be equipped with honeycomb along its inner chamber ring week, this honeycomb comprises a plurality of protruding groove combination, and protruding groove sets up towards the inside arch of capsule body, capsule body inner wall on be equipped with a plurality of heat dissipation strips along the honeycomb symmetry.
Preferably, the heat dissipation strip is an inclined rectangular hole.
Preferably, the honeycomb structure is composed of a plurality of polygonal convex groove combinations.
Preferably, the thickness of the honeycomb structure in the capsule body is reduced towards the non-pattern parts at two sides in sequence, so that the hard force is dispersed, and when the honeycomb structure is formed, the phenomenon that the hard force at the interface is concentrated and the damage occurs at the early stage because the tension difference between the position where the honeycomb structure is located and the non-pattern parts is large is prevented.
The utility model has the advantages and positive effects that: by adopting the technical scheme, the honeycomb structure arranged in the capsule body can prevent the phenomenon that the interface is damaged in the early stage due to the concentrated hard force of the interface because the tension difference between the part where the honeycomb structure is located and the non-pattern part is larger; and the ventilation strip arranged on the inner side of the capsule body plays a role in heat dissipation and ventilation.
The technical solution of the present invention is further described in detail by the accompanying drawings and examples.

Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.
The embodiment of the utility model provides a tire vulcanization capsule, including the capsule body 1 that corresponds green tire internal surface shape, the position that capsule body 1 corresponds the side wall of green tire is no decorative pattern portion 2, capsule body 1 inside be the cavity, capsule body 1 in be equipped with honeycomb 3 along its inner chamber ring week, this honeycomb 3 comprises a plurality of protruding groove 4 combinations, and protruding groove 4 sets up towards capsule body 1 inside arch, capsule body 1 inner wall on be equipped with a plurality of heat dissipation strip 5 along 3 symmetries of honeycomb, heat dissipation strip 5 for the slope slot.
In the embodiment, d is 0.2-2 mm, h is 0.2-2 mm, and w is 4-20 mm, and the stiffness of the convex groove 4 can be adjusted by adjusting the size of d and h in the actual use process.
The beneficial effects of the above technical scheme are: the honeycomb structure 3 arranged on the capsule body 1 not only meets the requirement characteristics of high-tension required parts, but also prevents the delay of the tire vulcanization time.
In one embodiment, the thickness of the honeycomb structure 3 in the capsule body 1 is gradually reduced towards the non-pattern parts 2 at two sides, so that the hard force is dispersed, and when the honeycomb structure 3 is formed, the phenomenon that the interface hard force is concentrated and the damage occurs at an early stage because the tension difference between the part where the honeycomb structure 3 is located and the non-pattern parts 2 is large is prevented.
In one embodiment, the honeycomb structure 3 is composed of a plurality of polygonal convex groove combinations.
It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalents, the present invention is also intended to include such modifications and variations.
