Direct sulfuration device of radial parting mold of radial ply tyre

Abstract

The invention relates to a radial tire vulcanization device, in particular to direct vulcanization equipment for a segmental mould of a radial tire. The direct vulcanization equipment overcomes the defaults of large volume, complex structure and high tire production cost of the radial tire vulcanization device in the prior art. The direct vulcanization equipment comprises an upper cover plate, a middle mold sleeve, a lower bottom plate, an upper side plate, an arc-shaped base, a pattern block and a lower side plate, wherein the pattern block is fixed on the inner surface of the corresponding arc-shaped base, and the arc-shaped base is positioned and connected with the lower bottom plate in the axial line direction of the mold without axial displacement, namely, the arc-shaped base and the lower bottom plate can not be moved vertically along with the middle mold sleeve and the upper cover plate; hydraulic locking devices are uniformly arranged on the outer edge of the lower bottom plate along the circumferential direction, lugs are arranged at the top ends of the piston rods of the hydraulic locking devices, open slots are correspondingly arranged at the bulgy part of the lower edge of the middle mold sleeve along the circumferential direction, and are mutually corresponding to hydraulic locking cylinders. The direct vulcanization equipment has the advantages that the structure is simple, the volume is small, the weight is light, the lifting force required for the equipment during mold opening and closing is greatly reduced, automatic locking of the vulcanization equipment is realized, the locking time is short, and the tire production cost is reduced.

Description

technical field [0001] The invention relates to a radial tire vulcanization device, in particular to a direct vulcanization equipment for a radial tire active mold. Background technique [0002] As we all know, the vulcanization of radial tires is completed by installing the active mold on the tire vulcanizer. Since the tire vulcanization is carried out under relatively high temperature and pressure, a large pressure will be generated in the tire mold to make the mold open. In order to offset the pressure inside the mold and make the vulcanization process go smoothly, the vulcanizer must provide a locking force to the mold after the mold is closed, so the tire mold must also work with the vulcanizer at the same time. According to the way of providing the locking force, currently commonly used vulcanizers are divided into two types: mechanical vulcanizers and hydraulic vulcanizers. Both of these methods use a device other than the mold, that is, a vulcanizer, to press and lo...

AI Technical Summary

Problems solved by technology

At present, bolts or lock rings have been used to lock them, but most of the existing locking methods are manual locking. Due to the high pressure in the entire equipment during the vulcanization process, the bolts or locks used for locking The number of rings is relatively large, so the locking time of manual locking is longer and the production efficiency is low
