Use method of intelligent hydraulic mold adjustment pressure exerting device

Abstract

The invention relates to a use method of an intelligent hydraulic mold adjustment pressure exerting device. The use method includes the steps: firstly, lifting an upper heating plate, placing a lower tire mold on a lower heating plate, declining the upper heating plate, enabling the upper heating plate to contact with an upper tire mold, fixing the upper heating plate and the upper tire mold, automatically calculating the needed extending stroke of a piston rod of a mold adjustment pressure exerting cylinder by a control system according to the measuring height of a tire mold, driving the piston rod of the mold adjustment pressure exerting cylinder and achieving an automatic mold adjustment function; secondly, driving a pressure exerting stopper to move towards a central hole of a beam and plug the central hole of the beam by a cylinder on the beam when the tire mold needs pressure exertion, controlling the piston rod of the mold adjustment pressure exerting cylinder to continue extending, and exerting pressure to the tire mold. The use method has the advantages that intelligent hydraulic automatic mold adjustment and pressure exerting functions are achieved, mold assembly precision of the device is improved, the quality of a vulcanized tire is also improved, mold adjustment auxiliary time is reduced, and production efficiency is greatly improved.

AI Technical Summary

Problems solved by technology

[0002] The mold adjustment function and pressurization function of the traditional vulcanizer are respectively realized by the mold adjustment mechanism, mechanical or hydraulic pressure device, the structure is complex, the precision is low, and the control is difficult

The mold adjustment mechanism is a key device in the tire vulcanizing machine that not only bears the vulcanization clamping force but also adapts to various tire molds of different specifications and models. Its structure is basically a T-shaped thread structure, which is difficult to process and low in precision. , low degree of intelligence, easy to get stuck, inconvenient maintenance and other problems;

[0003] The longer the service life of the traditional vulcanizer mold adjustment mechanism, the more serious the wear of the thread pair structure, the larger the gap between the thread pairs, and the accuracy of the thread pair structure is seriously out of tolerance, resulting in large deformation of the T-shaped thread, and the thread pair is damaged. Stuck and other mechanical failures

When the thread pair bears a huge vulcanization clamping force, it will also cause uneven force on the upper and lower molds of the tire, and the vulcanized tire will have flashing, which seriously affects the quality of the tire;

[0004] At the same time, the traditional vulcanizing machine mold adjustment mechanism has low intelligence and cannot automatically adapt to the adjustment of the height of tire molds of various specifications and models. Usually, the operator manually adjusts it many times to meet the requirements of the vulcanization process.

This also leads to a high error rate and a long auxiliary time for mold replacement, which affects equipment production efficiency
