Problems solved by technology

However, there are following deficiencies in the above-mentioned technical solution: firstly, the heating element is an open heating coil, and when the heat medium is filled, the heat medium will flow from the gap of the heating element to the surroundings, which reduces the contact time between the heat medium and the heating element , so that the heat medium cannot be fully heated when it is filled; secondly, radial convection is provided through the rotation of the fan blade integrated with the heating element, the rotation mode is single, the convection intensity generated is limited, and the effect of reducing the temperature difference is not ideal
[0005] To sum up, when the vulcanization bladder mechanism in the prior art is vulcanizing and heating the tire, the convection effect of the heat medium in the heating chamber is poor, the temperature difference is large, the heating efficiency is low, the vulcanization time is long, and the production cost is high.

Abstract

The invention relates to the technical field of tire forming, in particular to a curing bladder mechanism and a using method thereof. The curing bladder mechanism comprises a first heating cavity which is jointly formed by a curing bladder, a first fixing plate and a second fixing plate, wherein the first fixing plate and the second fixing plate are used for fixing the curing bladder, the first heating cavity can contain a heat medium, and a temperature sensor is arranged in the first heating cavity; an operation shaft is fixedly connected to the center of the first fixing plate, a first shellis connected to the bottom of the second fixing plate, and a heating mechanism is rotationally arranged above the center of the second fixing plate and is of a closed structure; a first through holeallowing the heat medium to pass through is formed in the bottom of the heating mechanism, and a second through hole communicating with the first heating cavity is formed in the top of the heating mechanism; and a rotatable dispersing mechanism is further arranged on the periphery of the heating mechanism, and a driving mechanism for driving the heating mechanism and the dispersing mechanism to rotate is arranged in the first shell. The curing bladder mechanism is high in heating efficiency and good in temperature balancing effect, the curing quality is improved, the use amount of the heat medium is reduced, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of tire building, in particular to a vulcanization bladder mechanism and its usage method. Background technique [0002] The tire needs to be vulcanized in the tire vulcanizing machine when it is built. The vulcanizing bladder mechanism is an important part of the tire vulcanizing machine. It is used to load the inner cavity of the green tire to be vulcanized and then pass it into the heat medium. The heat medium can be superheated water or high-temperature steam. Or high-temperature nitrogen and other heat-conducting media, the heat medium expands the vulcanizing bladder, and the expanded vulcanizing bladder is closely attached to the tire to be vulcanized to transfer heat energy, and at the same time cooperate with the vulcanizing mold to perform shaping and vulcanization operations. [0003] In the current vulcanization process, the temperature difference between the upper and lower sides and the front an...
