[0003] High-quality tire curing bladders can be reused many times, up to hundreds of times; while defective tire curing bladders can be reused less frequently, or even cannot be used once, such tire curing bladders will increase tire production. cost
At present, when the tire curing bladder is processed, a simple inspection will be carried out, such as thickness and thickness-based uniformity detection; the detection methods are few and incomplete, and the environment during the test is different from the working conditions. The number of times the tire curing bladder is used and structural improvement is of little significance

Abstract
The invention provides uniformity detection equipment and a detection method for a tire curing bladder, and relates to the technical field of tire curing bladder detection. The main body of the equipment (1) has an internal cavity (106) consistent with the inner contour of the tire produced corresponding to the tire curing bladder (3) to be tested, a sealing structure for sealing the opening end of the tire curing bladder (3), and a heating medium The pipeline, the detection hole (105) connected from the outside of the equipment main body (1) to the internal cavity (106), the movable probe (201) is located in the internal cavity (106) and the pressure sensor (2) is fixedly installed in the detection hole bit(105). Beneficial effects of the present invention: to simulate the operating conditions, the internal pressure of the tire curing bladder and the temperature of the medium can reach the actual application parameter values, the detection is the uniformity of the tire curing bladder after deformation during use, and the detection results can predict its use The number of times; it has a guiding effect on the structural improvement of tire curing bladders.
Description
technical field [0001] The invention relates to the technical field of tire vulcanization bladder detection, in particular to a tire vulcanization bladder uniformity detection device and a detection method thereof. Background technique [0002] The tire curing bladder is a hollow thin-walled rubber product, which is installed inside the tire curing machine as an inner mold for tire shaping during the vulcanization and molding process of the tire. Filling superheated water or compressed air into the tire curing bladder, so that the tire curing bladder stretches to support the tire rubber embryo, which is in contact with the tire tire. During the vulcanization process, the temperature is relatively balanced, so as to achieve the effect of uniform vulcanization of the tire and improve the balance performance of the tire. [0003] High-quality tire curing bladders can be reused many times, and the number of times of use can reach hundreds of times; while tire curing bladders wi...
