Problems solved by technology
In the existing vacuum extruder, the friction between the mud material and the forming mold frame wall during the extrusion process will cause the surface of the finished mud brick to appear frizzy. Usually, the surface of the body is rough, especially at the corners of the mud brick. Subsidence will seriously affect the strength and quality of mud bricks, and it is easy to cause cracks in the subsequent sintering process, which will reduce the qualified rate of finished tiles

Abstract
A vacuum extruder forming mold suitable for hollow square bricks of low-plasticity mud forming comprises a base plate, a mold frame and a support, wherein the mold frame and the support are arranged on the base plate. The mold frame is arranged at an extruding outlet corresponding to a vacuum extruder. The support and the mold frame are arranged on the two sides of the base plate correspondingly. Mold cores used for hollow mud blanks are arranged on the support. Wetting systems used for wetting the surfaces of the mud brick blanks are internally arranged on the frame edge of the mold frame and the mold cores. By the adoption of the vacuum extruder forming mold suitable for the hollow square bricks of low-plasticity mud forming, the abrasion between the mud blanks and the mold frame is reduced, the service life of the mold frame is long, galling and roughness of the surfaces of mud bricks are effectively reduced, and the quality of finished products is improved.
Description
technical field [0001] The invention relates to the technical field of ceramic production equipment, in particular to a vacuum extruder forming die for hollow square bricks suitable for forming low-plasticity mud. Background technique [0002] There are usually two existing ceramic tile production methods, one is mold dry pressing, that is, put the dry powder into the mold cavity, and press it into a green body by applying pressure, and the other is wet extrusion molding, that is, the mud It is extruded through a forming die on a vacuum extruder. In the existing vacuum extruder, the friction between the mud material and the forming mold frame wall during the extrusion process will make the surface of the finished mud brick rough. Usually the surface of the body is rough, especially at the corners of the mud brick. The subsidence seriously affects the strength and quality of mud bricks, and it is easy to cause cracks in the subsequent sintering process, which reduces the qua...
