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

Embodiment Construction
[0021] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.
[0022] A vacuum extruder mold frame with a wetting system, which is arranged at the corresponding extrusion port of the vacuum extruder, is characterized in that: the frame edge 1 of the mold frame is built with the surface of the inner frame 2 of the mold frame A wetting system 3 for wetting, the wetting system 3 includes a liquid inlet 31, a liquid distribution bar 32 and a liquid outlet 33;
[0023] The liquid inlet 31 and the liquid outlet 33 are respectively opened on the outer surface of the mold frame, the liquid distribution bar 32 is arranged along the frame shape of the frame edge 1, and the wetting liquid flows from the liquid inlet 31 enters, flows through the liquid distribution bar 32 along the frame distribution of the frame side 1 and flows in the mold frame, and finally flows out th...

Abstract
The invention relates to a vacuum extruder mold frame with wetting systems. The vacuum extruder mold frame is arranged at a corresponding extrusion opening of a vacuum extruder, and the wetting systems for wetting the surface of an inner frame of the mold frame are arranged in the frame edges of the mold frame and each comprise a liquid inlet, a liquid bypass stripe and a liquid outlet; the liquid inlets and the liquid outlets are formed in the outer surface of the mold frame, and the liquid bypass stripes are arranged along the frame types of the frame edges; wetting liquid enters the liquid inlets, is bypassed through the liquid bypass stripes, flows into the mold frame along the frame model distribution of the frame edges, and finally flows out from the liquid outlets; the liquid bypass stripes are provided with a plurality of wetting holes leading to the surface of the inner frame; and when the wetting liquid flows through the liquid bypass stripes, the surface of the inner frame is wetted through the wetting holes. By means of the vacuum extruder mold frame with the wetting systems, abrasion between the pug green bodies and the mold frame is reduced, the service life of the mold frame is long, the sgraffito and roughing phenomena on the surface of pug 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 mold frame with a wetting system. 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 water content About 17% of the plastic clay is extruded through a molding 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 qualified ...
