Ceramic shaft core forming die device

Abstract

The invention relates to the technical field of mold forming, in particular to a ceramic shaft core forming mold device which comprises a base plate, supports are fixedly mounted on the left side and the right side of the lower end face of the base plate correspondingly, storage mechanisms are mounted on the inner sides of the supports, vertical plates are fixedly mounted on the two sides of the upper end face of the base plate correspondingly, and guide assemblies are arranged in the middles of the vertical plates on the two sides correspondingly. Buffering mechanisms are symmetrically installed on the opposite faces of the vertical plates on the two sides, the upper ends and the lower ends of the buffering mechanisms are fixedly hinged to the base plate and the first sliding blocks correspondingly, a top plate is fixedly installed on the upper end faces of the vertical plates, and air cylinders are symmetrically and fixedly installed on the upper end face of the top plate. The upper die moves downwards to drive the buffer mechanism to move, the impact force of moving downwards of the upper die is buffered through cooling hydraulic oil in the buffer mechanism, and therefore impact force buffering in the die assembly process of the upper die and the lower die is achieved, the damage probability of the device is reduced, normal use of the device is guaranteed, and the service life of the device is prolonged.

Description

technical field [0001] The invention relates to the technical field of mold forming, in particular to a ceramic shaft core forming mold device. Background technique [0002] Ceramics, the utensils fired with clay are called pottery, and the utensils fired with porcelain clay are called porcelain. Ceramics are pottery, stoneware and porcelain. Many products are made of ceramics as raw materials, and ceramic shaft cores are among them. A ceramic product, ceramic shaft core will use a lot of mechanical equipment in the production, forming mold is one of them. [0003] However, existing ceramic shaft core molding dies still have some problems when producing ceramic shaft cores: 1. Most of the molding used in the production of ceramic shaft cores is to press the upper mold on the lower mold by the driving device when pressing. If the impact force generated during this period is too large, it is easy to cause the upper mold and the lower mold, and the contact part will be deforme...

AI Technical Summary

Problems solved by technology

[0003] However, existing ceramic shaft core molding dies still have some problems when producing ceramic shaft cores: 1. Most of the molding used in the production of ceramic shaft cores is to press the upper mold on the lower mold by the driving device when pressing. If the impact force generated during this period is too large, it is easy to cause the upper mold and the lower mold, and the contact part will be deformed, so that the upper and lower molds cannot be well combined, which will have a great impact on the product quality and the equipment itself at the production site.

2. At the same time, the mold device used in the production of the existing ceramic shaft core can only press and form a single specification product. If it is necessary to produce another set of specifications of the same series, the lower mold needs to be replaced, and a different one needs to be replaced. When lowering the mold, it is necessary to manually adjust the position of the lower mold to ensure the alignment of the lower mold and the upper mold. The process is more troublesome. If the lower mold is pressed down, the upper mold cannot squeeze the material on the lower mold well.
