Electromagnetic heating tyre mould

Abstract

The invention discloses an electromagnetic heating tyre mould which comprises an upper mould plate and a lower mould plate. The upper mould plate and the lower mould plate jointly form a closed integrated structure. An upper side plate is arranged on the upper mould plate; a lower side plate is arranged on the lower mould plate; electromagnetic heating devices are arranged on the upper side plate and the lower side plate; and a power interface is arranged on one side of each of the electromagnetic heating devices. By means of the electromagnetic heating devices, the temperature in a tyre vulcanizing process is precisely controlled conveniently, and stable heat energy can be provided. The vulcanizing time in the machine can be shortened, the production efficiency is increased, and the uniformity of the tyre vulcanizing process is enhanced greatly, and the tyre quality is improved. More important, the electromagnetic heating devices replace original steam heating, so that a mass of coal is not needed for combustion, and therefore, exhaust gas emission is effectively reduced, and the ecological environment is protected.

Description

technical field [0001] The invention relates to a tire mold, in particular to an electromagnetic heating tire mold. Background technique [0002] With the rapid development of transportation, the requirements for tire quality are getting higher and higher. Vulcanization is the last and most important process in the tire processing process. Its purpose is to change the plastic state tire into the elastic state tire. And to achieve the best physical and mechanical properties of each part. At present, water tires or bladders are installed in the tire base during vulcanization, and high-pressure hot water is injected into the water tires, and the expansion pressure of the water tires or bladders is used to make the outer tires full of molds. The water pressure column is cold and the tank is filled directly with steam vulcanization, but steam vulcanization makes it impossible to accurately control the temperature of the tire during the vulcanization process, and the heat energy i...

The water pressure column is cold and the tank is filled directly with steam vulcanization, but steam vulcanization makes it impossible to accurately control the temperature of the tire during the vulcanization process, and the heat energy is not stable enough, which affects the quality of the tire. It is also a poor conductor of heat, so steam needs a lot of coal to burn, which wastes resources and pollutes the environment
