Energy-saving unpowered lower opening type tyre vulcanizing segmented mold

Abstract

The invention relates to an energy-saving unpowered lower opening type tyre vulcanizing segmented mold which comprises a vulcanizing upper mold, a vulcanizing lower mold and a segmented module. The segmented mold is characterized in that the vulcanizing upper mold comprises an upper tapered mold sleeve, the upper surface of the inner side of the upper tapered mold sleeve is fixedly provided with an upper steel ring and an upper tyre side plate, a guide block is arranged on the inner tapered surface of the upper tapered mold sleeve, the vulcanizing lower die comprises a lower segmented mold baseplate and a lower tyre side plate fixedly arranged on the lower segmented mold baseplate, the segmented module is connected to the lower segmented mold baseplate and radially moves through a radial sliding device arranged on the lower segmented mold baseplate, and an inclined guide groove which is matched with the guide block is also arranged on the outer side surface of the segmented module. The segmented mold provided by the invention can not only save energy sources and is convenient for operating, but also reduces the equipment cost and has high operation safety.

Description

technical field [0001] The invention relates to a vulcanization active mold, in particular to an energy-saving non-powered bottom opening type tire vulcanization active mold. Background technique [0002] The tire joint mold is a relatively critical mold in the tire production process. The heating form and operation form of the mold directly affect the quality of the tire and the safety of production, and also affect the waste of heat energy. Therefore, it is very necessary to completely transform the structure of the existing joint mold. . The current structure of the active mold is that the active module is installed on the upper tapered mold sleeve, so when the mold is opened, the active module is lifted, so once the bolts and other connecting parts connecting the active module are damaged (or broken), it will cause active Modules falling from a high altitude will damage the mold or vulcanization equipment if it is light, or cause personal injury or death if it is seriou...

AI Technical Summary

Problems solved by technology

The current structure of the active mold is that the active module is installed on the upper tapered mold sleeve, so when the mold is opened, the active module is lifted, so once the bolts and other connecting parts connecting the active module are damaged (or broken), it will cause active The module falling from high altitude will damage the mold or vulcanization equipment if it is light, and it will cause personal injury or death if it is serious. It has always been a safety hazard for tire manufacturers, and it has not been solved so far.

In addition, the expansion and contraction of the current active mold is operated by a power water cylinder or a power oil cylinder, which not only wastes power energy but also affects the quality of tires and the production environment of vulcanizing machines.

In addition, the heating of the current active mold is vulcanized by heating and vulcanizing on the upper and lower hot plates, resulting in low heat transfer efficiency and serious heat loss.
