Abstract

The invention discloses a tire curing capsule and a preparation method thereof, and relates to the technical field of tire curing capsules. The capsule comprises a middle body, and capsule shoulder parts, capsule side parts, capsule neck parts and edge clamping parts which are sequentially and symmetrically distributed on the two sides of the middle body; the outer walls of the capsule neck partsprotrude outwards to form first protrusions and second protrusions, the concave positions between the first protrusions and the second protrusions are called as first grooves, and the concave positions between the second protrusions and the edge clamping parts are called as second grooves; the front ends of the edge clamping parts are provided with front shrinking ends, expanding parts are arranged in the circumferential direction, and conical parts are arranged at the joints where the edge clamping parts and the second grooves are connected. Compared with the prior art, the beneficial effectsare that the capsule neck parts and the edge clamping parts at the assembly part of the tire curing capsule and a tire vulcanizing machine are improved, so that the assembly stability and sealing performance of the tire curing capsule and the tire vulcanizing machine can be improved; and in combination with a preparation method of the tire curing capsule, the failure rate caused by damage to thetire curing capsule at the assembly position of the tire curing capsule and the tire vulcanizing machine during use is reduced.

Description

technical field [0001] The invention relates to the technical field of tire curing bladders, in particular to a tire curing bladder and a preparation method thereof. Background technique [0002] The tire curing bladder is a hollow thin-walled rubber product, which is installed inside the tire curing machine and used as an inner mold for tire shaping during the tire vulcanization molding process. The tire vulcanization bladder includes a central body that plays the main role of expansion, bladder shoulders, bladder sides, bladder neck, and clamping edge that are symmetrically distributed on both sides of the intermediate body in sequence; among them, the bladder neck and clamping edge will be vulcanized with the tire. machine to cooperate. Fill the inside of the tire curing bladder with superheated water or compressed air and other media, so that the tire curing bladder stretches and supports the tire rubber embryo, which fits the tire tire, and uses the flow and heat trans...
