As shown in Figures 13, 14 and 15, a combined back mold core for the production of anti-shedding ceramic tiles, wherein the back mold core for the production of anti-shedding ceramic tiles is higher than the surface vulcanized glue 8 of the combined mold core in a non-working state and The height difference is equal to the moving stroke of the back mold core for the production of anti-shedding tiles.

As shown in Figures 13, 14, and 15, a combined back mold core for the production of anti-falling ceramic tiles, wherein the combined core frame and the groove of the movable core piece can be assembled with the anti-falling ceramic tile production of the present invention. Back mold cores and tile molds with similar functional structures.

Further explain the working principle of a back mold core for the production of anti-shedding ceramic tiles, a combined back mold core and a ceramic tile of the present invention, a back mold core for the production of anti-shedding ceramic tiles, as shown in Figure 1-12, Figure 16, As shown in -18, specifically taking a back mold core for the production of a single piece of 45*95 external wall tiles for the production of anti-shedding tiles as an example, the size of the core panel 1 is 106mm long * 50mm wide * 10mm high, the core panel 1 The surface is covered with 4 strips of core surface vulcanizate 6 with a width of 5mm and a height of 1.2mm. At the middle of the two ribs in the middle, a through-hole groove with a width of 5mm and a length of 82mm is cut by wire cutting. The local position of the hole groove is narrowed by 1mm, so that the empty space in the iron part space of the through-hole groove is 80*3, that is, a space of 1mm thickness is reserved on each side for filling the glue of the vulcanized rubber 6 on the core surface, which weakens the rigid friction. Influence; when pouring and vulcanizing the core surface vulcanizate 6, the rubber-coated mold on the front surface is pre-engraved with a positive wave pattern at the position of the corresponding core panel groove cavity 101, and the back mold has two grooves that penetrate into the core panel groove. For the insert of cavity 101, the head of the insert is pre-engraved with a reverse wave pattern, forming an equidistant gap with the forward wave pattern, and the thickness is controlled at 1mm. A sealing groove with a width of 1 mm and a depth of 2.5 is engraved on the inner surface of the panel 1 at a distance of 0.8-1 mm from the edge for sealing.

The size of the core backplane 2 is 104mm long * 48mm wide * 25mm high, the inner outermost circle is a dust-proof sealing edging with a height of 2mm and a width of 0.8mm, and the thickness of the backboard force transmission step 204 to the back is 23mm , corresponding to the position where the embossed insert tooth 3 is installed, mill out 2-3 steps, from the back of the core back plate 2 with the position corresponding to the embossed insert tooth 3, the through hole is connected to the embossed insert screw hole 205, The embossed insert teeth 3 are connected and fixed to the mold core backboard 2 with the embossed insert teeth connecting screws 301 .

Two steps are milled out on the back of the core back plate 2 where the plug screw 4 is installed to control the movable stroke of the plug screw. The plug screw is selected with a length of 16mm, a rod diameter of 6mm, and a step thickness of 15.2mm. The active stroke of the mold core is 0.8mm. After installing the PU elastic glue or spring 5, use the plug screw 4 to connect and install the mold core panel 1 and the mold core backplane 2, leaving a combined active stroke of 0.8mm. The head of the grain insert tooth 3 is just in contact with the highest point of the corrugated vulcanizate 601 .

When the tile blank is pressed, under the reaction force of the tile powder, the external force is greater than the elastic force of the PU elastic glue or the spring 5, the core panel 1 and the core back plate 2 are closed, and the embossed insert teeth 3 are also Move 0.8mm in the direction of the core panel 1. At this time, the part that was originally wrinkled vulcanized rubber 601 is subjected to bidirectional pressure, and the corrugation is flattened. Since the vulcanized rubber is solid and the volume remains unchanged, the wrinkle The pleated vulcanizate 601 is forced to deform to both sides, thereby pushing the originally right-angled sides and corners to expand and deform, so that the back pattern of the tile forms a dovetail groove structure that is large inside and small outside.

At the end of the pressing work of the tile body, during the process of the pressure subsidence of the press, the embossed insert teeth 3 move backward, leaving space for the wrinkled vulcanized rubber 601 to retreat and recover. After the deformation is recovered, a dovetail groove has been formed. The side edge of the wrinkled vulcanized rubber 601 at the position of the structure has been restored to a right angle, which can be demolded smoothly.

The invention makes full use of the elastic characteristics of the polyurethane vulcanizate, and also utilizes the principle of the shortest straight line distance between two points in geometry, and utilizes the physical properties of the solid volume invariant, so that the curve and the straight line of the wrinkled vulcanized rubber 601 position The transformation process realizes the formation of the tile dovetail groove structure and the smooth demoulding.

For the back mold core applied to large wall tiles and floor tiles, the above mold cores can be made into basic units one by one and then combined. Taking the 300*600 tile mold core as an example, a composite back mold for the production of anti-shedding tiles The mold core, as shown in Figures 13, 14 and 15, the size of the original tile mold core is 700mm long * 320mm wide * 60mm thick, the thickness of the above-mentioned back mold core for the production of anti-shedding ceramic tiles in the non-working state is 33.8mm , mill 6 rectangular grooves with a depth of 33mm on the front of the large tile mold core. After the large tile mold core is covered with vulcanized glue 8 on the surface of the combined mold core, the back mold core for anti-shedding tile production is more than the surface of the combined mold core. The height of the glue 8 side is 0.8mm, that is, it is higher than the movable stroke of the back mold core for the production of anti-shedding tiles.

Similarly, in the process of pressing and demoulding the tile blank, the back mold core for the production of anti-shedding tiles as the basic unit works as a single unit. For large tiles, a corresponding dovetail groove back pattern is formed in this part. For the anti-shedding tiles The application of the combined back mold core for production, because the mold sizes used by different production enterprises are different, if the back mold core for the production of anti-shedding ceramic tiles of the present invention is directly applied, because the size of the ceramic tile mold on each hydraulic press production line is different. Various sizes can only be customized for maintenance, which is very unfavorable to the popularization of industrialization. Formatting the 701 size of the groove of the movable mold core and the format and installation of the back mold core for the production of anti-shedding tiles will greatly improve the cross-dovetail. The application degree of groove tile mold, maintenance or replacement can be completed quickly, which can produce unexpected industrial effects.
