Description

Technical Field

[0001] The invention relates to the technical field of tire vulcanization equipment, and in particular to a temperature measuring device and a tire mold for tire vulcanization. Background Art

[0002] During the vulcanization process of the tire, in order to better determine or optimize the vulcanization process, it is necessary to measure and analyze the temperature at different positions of the tire. At present, the common tire temperature measurement method is to directly bury the temperature measuring head with the temperature measuring wire and part of the temperature measuring wire into the tire mold, and the temperature measuring wire is led out from the outside of the tire mold. In the specific use process, the opening and closing of the tire mold will cause the temperature measuring wire to shrink, and a certain length of the temperature measuring wire needs to be reserved. However, the reserved temperature measuring wire is easy to interfere with the placement of the tire blank and the removal of the tire, making it difficult to achieve continuous tire production.

[0003] At the same time, the temperature measured by this tire temperature measurement method is not the temperature at the tire mold cavity surface, which will lead to inaccurate vulcanization temperature measurement and increase the time of invalid vulcanization; further, most of the temperature measuring lines are pulled back and forth during the vulcanization process and exposed for a long time, which will affect the temperature measurement accuracy and make disassembly and assembly difficult.

[0004] Therefore, developing and designing a temperature measuring device and tire mold for tire vulcanization that has precise docking, ensures more accurate temperature measurement, and is easy to install and disassemble is a problem that needs to be solved urgently at this stage.
