Back mold core for anti-falling ceramic tile production and combined back mold core thereof as well as made ceramic tile

Abstract

The invention discloses a back mold core for anti-falling ceramic tile production. The back mold core comprises a mold core panel of a mold core panel groove cavity provided with a through hole in aniron piece, a mold core backboard provided with an elastic rubber tank hole and a shoulder screw sliding rod guide hole, mold core face vulcanized rubber which is provided with corrugated vulcanized rubber in the corresponding position of the a mold core panel groove cavity and integrally coats the front face of the mold core panel, embossing insert teeth inserted into the mold core panel groove cavity, PU elastic rubber or springs elastically stretching the mold core panel and the mold core backboard and shoulder screws for positioning and limiting the movable stroke of the mold core panel and the mold core backboard, wherein a circle of dustproof sealing edge with the greater height than the movable stoke is arranged at the outermost side of the contact surface of the mold core panel orthe mold core backboard. The back mold core for anti-falling ceramic tile production comprises a combined mold core frame, a plurality of movable mold core piece groove holes, combined mold core surface vulcanized rubber which is hollowed out in a position corresponding to the movable mold core piece groove hole, and back mold cores for anti-falling ceramic tile production, which are equal to thenumber of the movable mold core piece groove holes.

Description

technical field [0001] The invention relates to the field of ceramic production, more specifically, to a back mold core for anti-falling ceramic tile production and a combined back mold core and the finished ceramic tile. 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.

[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. CN209920141U discloses a ceramic tile mold and extended ceramic tile mold support and ceramic tiles pressed by the mold. The utility model discloses a ceramic tile mold and expanded ceramic tile mold support. The dovetail groove has the disadvantages of small effective structure, mold jamming due to the movable mouth, which is easy to accumulate powder, and requires a large space, which is difficult to apply to small-sized tiles. The internal structure of the mold determines that there are many customized components, which leads to high costs.

[0004] Patent No. CN209599475U discloses a self-stress hydraulic dovetail groove tile mold and tiles pressed by the mold. The utility model discloses a self-stress hydraulic dovetail groove tile mold. This technology utilizes the fluidity and volume stability of the liquid However, this technology has the disadvantages of filling hydraulic fluid into the mold, which may easily lead to cracking of the vulcanized rubber on the surface and oil leakage failure, and requires high processing precision and high production costs.

[0005] Patent No. CN110712276A discloses a tile mold with rotating movable teeth and tiles pressed by the mold. The invention discloses a tile mold with rotating movable teeth. This technology uses cross-shaped oblique openings to form dovetail grooves. The effective structure is small, and the mold is stuck due to the movable mouth, which is easy to accumulate powder. The space required is large and it is difficult to apply to small-sized tiles. The internal structure of the mold determines that there are many customized components, which leads to high costs.

[0006] 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
