High-pressure slurry injector with quick ceramic forming and die releasing functions

Abstract

The invention discloses a high-pressure slurry injector with quick ceramic forming and diereleasing functions. The high-pressure slurry injector comprises a frame-shaped framework. A slide rail is arranged on the top of the framework, the framework is provided with a slide seat, a pressing die head is hoisted on the slide seat, a right half ceramic forming die and a left half ceramic forming die are respectively mounted on the pressing die head and a left-side support of the framework, a bottom die and a lifting cylinder are arranged below the left half ceramic forming die, a slurry injection system is mounted on a base of the framework, and a hydraulic integrated pump station is mounted on the right side of the framework. The high-pressure slurry injector is characterized in that a master pressurization cylinder and two auxiliary cylinders for opening and closing the dies are arranged between a right-side support of the framework and the pressing die head in a connected manner; the slurry injection system comprises a mud blank forming die, a pneumatic diaphragm pump and a slurry injection pipe, the forming dies are connected with one end of the slurry injection pipe, a high-pressure slurry storage tank is communicated with the other end of the slurry injection pipe, and an outlet of the pneumatic diaphragm pump is communicated with the high-pressure slurry storage tank via a slurry supply pipe B; the high-pressure slurry injector is provided with a pressurization device. The high-pressure slurry injector has the advantages that the dies can be closed accurately, the pressure is stable, the die releasing time is short, products are good in quality and high in qualified rate, and the high-pressure slurry injector is mainly used for manufacturing ceramic blanks.

Description

technical field [0001] The invention relates to ceramic production equipment, in particular to a high-pressure grouting machine for rapid prototyping and demoulding ceramics. Background technique [0002] At present, manual grouting is mainly used in domestic ceramic production and processing, which has low production efficiency, high labor intensity, and difficult to improve product quality. The high-pressure grouting machine mainly produced in Germany has successfully replaced manual grouting in the world, and this kind of grouting equipment has begun to be introduced in China. However, the structure of this equipment is very complicated, the cost is extremely high, and the purchase price is higher, and there are the following disadvantages: a single oil cylinder is used to open and close the mold and compress the mold, and the precision of mold closing is not high, which affects the molding surface quality of the mud blank. Pressure is limited and unstable. Especially d...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the existing high-pressure grouting machine uses a single cylinder to open and close the mold, and the precision of mold closing is poor, which affects the quality of the mud forming surface, the pressure is unstable and the pressure of the grouting system is small, which leads to the speed of mud forming. Slow, high water content of mud, low yield, poor product quality and other problems, to provide a rapid prototyping demoulding ceramic high-pressure grouting machine
