Description

[0001] The invention relates to the technical field of slip casting machines, in particular to a full-automatic ceramic high-pressure hollow slip casting machine. Background Art

[0002] High-pressure grouting molding is actually a filtering process. During the grouting process, the mud particles move to the working surface of the side valve mold and deposit in sequence, thus forming a green body with a certain strength.

[0003] The fully automatic ceramic high-pressure hollow grouting molding machine utilizes the filterability of porous resin materials to pressurize and dehydrate the mud injected into the resin side valve mold. After a period of pressurization, the green body reaches the predetermined thickness, the mud pressure is released and the excess mud is discharged; then high-pressure gas is introduced to further consolidate the strength of the green body; after the consolidation stage is completed, the mold is opened and the green body is taken out.
