a tire mold

Abstract

The invention relates to the technical field of tyre manufacturing, and aims at providing a tyre mold. The provided tyre mold comprises a mold shell assembly and a cavity assembly arranged in the moldshell assembly. A temperature measuring hole is formed in an upper side plate of the cavity assembly and internally provided with a temperature measuring element. The tyre mold is provided with a first wire passing groove communicating with the temperature measuring hole. The mold shell assembly is provided with a second wire passing groove communicating with the first wire passing groove, and atemperature measuring wire connected with the temperature measuring element penetrates through the first wire passing groove and the second wire passing groove to be guided out. In the tyre mold preheating and tyre vulcanization process, the temperature of the tyre mold cavity face is monitored, and tyre damage is avoided. Meanwhile, the problems that the temperature measuring wire influences thework of the tyre mold, and the temperature measuring wire is extruded in the usage process are solved, and accordingly the service life of the tyre mold is prolonged.

Description

technical field [0001] The invention relates to the technical field of tire manufacturing, in particular to a tire mold. Background technique [0002] During the production of existing tires, the temperature and time of tire vulcanization need to be strictly controlled. If the temperature of green tire green tires is not well controlled, the tires will be scrapped and the qualified rate of tire quality will be affected. The vulcanization temperature is low, under the same time, it will produce undersulfur, undersulfur tire rubber reaction is not sufficient, the physical properties are poor, when the undersulfur is serious, it will be sticky, and it cannot be used. Poor, and easy to delaminate and damage; high vulcanization temperature, under the same time pressure, oversulfurization will occur, and oversulfurized tire rubber will become brittle, and it also has poor wear resistance during use, and it will also cause chipping and chipping.

AI Technical Summary

Problems solved by technology

[0002] When producing existing tires, it is necessary to strictly control the temperature and time of tire vulcanization. Poor control of the vulcanization temperature of green tire blanks will lead to tire scrapping and affect the qualified rate of tire quality

The vulcanization temperature is low, under the same time, it will produce undersulfur, undersulfur tire rubber reaction is not sufficient, the physical properties are poor, when the undersulfur is serious, it will be sticky, and it cannot be used. Poor, and easy to delaminate and damage; high vulcanization temperature, under the same time pressure, oversulfurization will occur, oversulfurized tire rubber will become brittle, poor wear resistance when used, and the phenomenon of chipping and chipping will also occur

[0003] Existing tire molds basically do not have the function of measuring the temperature of the mold. Even if there is, only a wire hole for temperature measurement of a tire is reserved on the mold. However, when the tire temperature is detected through the wire hole, it is necessary Inserting the temperature detection piece into the tire will damage the surface of the tire

The mold can only be used for temperature measurement. After the temperature measurement is completed, it cannot be used for vulcanization of normal tires.

However, when the temperature measurement line is arranged, it is not necessary to consider the non-temperature measurement working conditions of the mold, nor does it consider the influence of the mold opening and closing action on the line.
