Grouting forming method for ceramic blanks

Abstract

A grouting forming method for ceramic blanks comprises the steps of grouting, slurry blanking, slurry mold injection preparation and slurry mold injection forming. According to the grouting forming method for the ceramic blanks, the liquid level in a grouting barrel is controlled through a first liquid level and a second liquid level, the relatively constant grouting pressure can be kept in grouting and is small, slurry is prevented from leaking from seams of a mold, the effect that the same height (a preset liquid level) is kept when the slurry enters the mold is guaranteed through a horizontal liquid level device before slurry mold injection, it is ensured that air in a pipeline is completely exhausted, and the thickness difference between the blanks is reduced.

Description

technical field [0001] The invention relates to a ceramic manufacturing technology, in particular to a method for grouting a ceramic body. Background technique [0002] Ceramic products are usually formed by grouting. The traditional process is: the mud adjusted by the raw material department is injected into the mold by the plug pump through the pipeline, and the sizing height in the mold is controlled by the liquid level pipe. After the mud is formed in the gypsum mold, The excess pulp in the mold is discharged into the pulp discharge bucket by natural pulp discharge. The traditional process suffers from the following disadvantages: [0003] 1. The slurry is directly supplied into the gypsum mold by the plug pump, and the slurry supply pressure is relatively large, resulting in serious slurry leakage of the mold and on-site slurry pollution; [0004] 2. The slurry supply pressure is large, the sizing speed in the mold is fast, and the air in the pipeline and the mold can...

AI Technical Summary

Problems solved by technology

[0003] 1. The slurry is directly fed into the gypsum mold by the injection pump, and the slurry supply pressure is relatively high, resulting in serious slurry leakage of the mold and mud pollution on site;

[0004] 2. The slurry supply pressure is high, the sizing speed in the mold is fast, and the air in the pipeline and the mold cannot be completely emptied, resulting in defects, resulting in a thickness difference between the first green body and the last green body: 0.5-0.7mm
