Ceramic tile mold, expanded ceramic tile mold support and ceramic tile formed through pressing of mold

Abstract

The invention discloses a ceramic tile mold, an expanded ceramic tile mold support and a ceramic tile formed through pressing of the mold. The technical improvement is achieved on the basis of the public technology of a manufacturing equipment and manufacturing method of a ceramic tile back face cross dovetail groove disclosed in the patent CN108466355A, the problems existing in the technology aresolved, an exhaust system is additionally mounted according to the characteristics of the improved mold, the automatic production process is simplified, the production efficiency is improved, and theproduction cost is reduced. Bevel edge grain teeth of a bevel edge grain part of the public technology are optimized, each bevel edge grain tooth is made into an independent bevel edge forming part,upper teeth on a bevel edge grain part in the original public technology are removed, and the elastic force of springback PU elastic rubber or springs of the bevel edge forming parts is used for replacing the retraction function of the upper teeth. Furthermore, the expanded ceramic tile mold support is specifically provided. The ceramic tile mold and ceramic tile molds with the similar function can be made into mold units, the mold units are assembled on a combined mold, the requirements of ceramic tile molds of various different sizes can be met, the maintenance process can be simplified, themold units needing to the maintained can be directly replaced, and other mold units are not influenced.

Description

technical field [0001] The invention relates to the field of ceramic production, and more specifically relates to a tile mold, an expanded tile mold support and tiles pressed by the mold. Background technique [0002] In the existing ceramic tile production process, the ceramic tile embryo body is made of powder and pressed by ultra-high pressure. The ceramic tile embryo body is molded by mechanical equipment with fixed upper and lower molds. For many years, the society has always hoped to produce a dovetail groove. ceramic tiles, and also disclosed ceramic tiles with various dovetail groove characteristics, but did not provide effective specific implementation equipment and solutions. Because the mold needs to withstand ultra-high pressure and the fixed mold cannot be demolded after forming the dovetail groove structure, this kind of dovetail groove Ceramic tiles with structural properties have been conceived but never realized.

Problems solved by technology

[0002] In the existing ceramic tile production process, the ceramic tile body is made of powder and pressed by ultra-high pressure. The ceramic tile body is molded by mechanical equipment with fixed upper and lower molds. For many years, the society has always hoped to produce a dovetail groove. ceramic tiles, and also disclosed ceramic tiles with various dovetail groove characteristics, but did not provide effective specific implementation equipment and solutions. Because the mold needs to withstand ultra-high pressure and the fixed mold cannot be demolded after forming the dovetail groove structure, this kind of dovetail groove Ceramic tiles with structural performance have been conceived but never realized

[0003] Patent No. CN108466355A discloses a manufacturing equipment and method of intersecting dovetail grooves on the back of ceramic tiles. The manufacturing equipment disclosed in this invention can produce dovetail grooves with crossed dovetail grooves within a certain size of ceramic tiles and a small amount of production. Ceramic tiles, but this technology has the following disadvantages that affect the industrial production of ceramic tiles. First, this technology has no sealing components, and the dust mixed in the exhaust will block the mold during mass production, filling the gaps in the mold, causing mold damage or reducing the tile pressing accuracy; second. , this technology does not treat the front surface of the mold. In mass production, due to the contact and friction between the iron mold and the dust, the dust will stick to the mold during demoulding, which will affect the accuracy; finally, the cross-dovetail grooves are fixed on the hypotenuse. On the grained strips, they are not only related to each other, but also affect each other, which will easily cause the die to be jammed or increase the wear of the die and reduce the service life of the die when the material is slightly deformed. Moreover, the pressure of the hydraulic press is transmitted to the bottom platen through the beveled edge molding, which increases the risk of damage

[0004] The existing ceramic tile back pattern mold core board, because it has to bear the ultra-high pressure when the hydraulic press presses the tile body, the mold core of the whole board is in contact with the tile panel, and the mold core is made of steel, with high density and heavy weight , the manufacturing equipment disclosed above belongs to a movable mold, which is a new type of technology. When a similar movable mold is introduced, especially when a similar movable mold is directly applied to the pressing of a large-area ceramic tile body, the failure rate will increase, and It cannot be repaired regionally, reducing production efficiency, and because the shrinkage rate of the ceramic tile body powder is different, the tile mold sizes used by different manufacturers are different, requiring a large number of customized molds, and the direct application of movable molds is not conducive to new technologies the popularity of
