Technical Field
The utility model relates to the field of ceramic tile production, in particular to a ceramic tile with a double-sided dovetail groove and an upper mold core for producing a ceramic tile blank.
Background
In the existing ceramic tile production process, a ceramic tile blank is formed by firstly pressing powder through ultrahigh pressure of a press and then closing a die through the die. However, the tile often has a phenomenon of hollowing or falling off in use, wherein the falling off between the bonding layer and the facing tile is particularly serious, and is mainly caused by the failure of bonding force.
The reason for this problem is that the tile is made by positive demoulding during demoulding, which results in the cross section of the back-embossed part of the tile being small at the top and large at the bottom, and the structure is shown in figure 1. When the tile adopts the back-grain section structure shown in fig. 1, the common shedding factors are as follows: the back grain groove is in a trapezoidal shape, the outside is large, and the inside is small, so that a buckle structure cannot be formed; the temperature difference is too large all the year round, the ceramic tile expands with heat and contracts with cold, and the water in the ceramic tile freezes and expands in part of areas below zero DEG C in winter, so that the ceramic tile falls off; the water absorption rate of the ceramic tile is too high, the ceramic tile is insufficiently soaked in water when being paved, and the moisture of a dry layer is absorbed too early after being paved; in the firing process of the ceramic tile, the base glaze of the blank has demoulding property; natural external force: the external impact of strong wind, heavy rain, hail and the like on the ceramic tile.
Although the problem of tile falling off is also solved by adopting the tile with the unilateral dovetail groove structure, the defects still exist: 1. although the problem of ceramic tile falling is solved, the ceramic tile with the structure is difficult to produce in large quantity, and even the quality of the produced ceramic tile is not stable enough; 2. the back grain of the ceramic tile needs to be processed by a numerical control engraving machine in the production of the ceramic tile, so that the production cost of the ceramic tile is high.
