Driving device for forming machine

Abstract

The invention discloses a driving device for a forming machine. The driving device comprises a support, a lower die substrate, a lower die inner sleeve, a lower die outer sleeve and an air supply unit. The lower end of the lower die inner sleeve penetrates the support, and a fixing frame for fixing the lower die inner sleeve on the support is arranged at the bottom of the support correspondingly. According to the driving device, the design is ingenious, when the a lower die outer sleeve presses down, air in sealed space is compressed automatically, and a spring function is provided; the air pressure of the sealed space can be controlled skillfully by the air supply unit according to the work condition of the lower die substrate to obtain corresponding elastic force, so that the driving device is flexible in stretching and retraction and high in stability.

Description

Technical field [0001] The present invention relates to the technical field of molding machines, in particular to a driving device of a molding machine. Background technique [0002] With the development of science and technology, modern people pay more and more attention to the improvement and perfection of molding machines. Therefore, there are various molding machines on the market, each with a different design concept, and strive to meet the requirements of different users. At present, although the telescopic mechanism on the existing molding machine can roughly meet the requirements of use, its design is not clever enough, and they have failed to break through the traditional structural design. All of them use spring-type telescopic mechanisms, and the lower mold telescopes to complete the packaging process. The following problems occur: 1. As the rigidity of the pitch increases and the elastic force increases during the compression of the spring, the lower die casing bears...

AI Technical Summary

Problems solved by technology

At present, although the telescopic mechanisms on the existing molding machines can roughly meet the requirements of use, their designs are not ingenious enough, and none of them can break through the traditional structural design. They all use spring-type telescopic mechanisms. The following problems arise: 1. During the compression process of the spring, as the rigidity of the pitch increases and the elastic force increases, the casing of the lower die bears a large load, which reduces the service life of the casing and shortens the replacement cycle

2. The spring is prone to fatigue and damage under the action of repeated alternating carrier, which affects the normal operation of the machine

3. Due to the effect of the eccentric carrier of the spring, the up and down telescopic movement of the lower mold casing is often inflexible, or even stuck, which seriously affects the completion of the packaging process, greatly reduces work efficiency, and is difficult to guarantee product quality, which is not conducive to enterprise development
