Description

Technical Field

[0001] This utility model relates to the field of ceramic tile technology, and in particular to a ceramic tile with an easy-to-demold and anti-detachment back pattern. Background Technology

[0002] In existing tile production processes, powdered raw materials are pressed into shape under ultra-high pressure using mechanical equipment, and then formed into a tile body by the closing of fixed upper and lower molds. Simultaneously, a textured back structure with concave or convex patterns is formed on the back of this body, designed to increase the bonding area during subsequent construction. During installation, the tiles are wet-applied to the wall using tile adhesive or cement mortar, relying on the adhesive strength of the bonding material for fixation. However, this technical system has the following problems.

[0003] The textured back pattern enhances mechanical bonding strength by widening the contact interface between the tile and the adhesive layer, making it a key design feature against detachment caused by environmental stresses (temperature and humidity cycles, load changes). However, the raised and recessed patterns of the back pattern deeply interlock with the mold surface during pressing, resulting in significant frictional resistance between the tile body and the mold during demolding. This resistance can easily cause localized sticking of the tile body to the mold, damaging the integrity of the texture. Even worse, forced demolding may lead to edge chipping or micro-cracks in the tile body, reducing the product yield.

[0004] In current processes, the back texture design and demolding efficiency of ceramic tiles restrict the quality and application of ceramic tiles. There is an urgent need to develop a ceramic tile that takes into account molding quality, demolding efficiency, and anti-fall-off properties. Utility Model Content

[0014] The first bottom surface is connected to the surface of the tile body, and the two ends of the first bottom surface are respectively connected to the bottom end of the first outer side surface and the bottom end of the first inner side surface.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] The following is in conjunction with the appendix Figures 1 to 5 The technical solution of this utility model will be further illustrated through specific implementation methods.

[0040] A ceramic tile with an easy-to-demold and anti-detachment back pattern includes a ceramic tile body 0, wherein the ceramic tile body 0 is provided with an anti-detachment raised pattern 1 and an auxiliary raised pattern 2, wherein the anti-detachment raised pattern 1 and the auxiliary raised pattern 2 protrude from the surface of the ceramic tile body 0;

[0041] The anti-detachment texture 1 includes a plurality of concentrically arranged anti-detachment rings 10, which are arranged symmetrically around the center of the ceramic tile body 0. The vertical cross-section of the anti-detachment texture 1 is a parallelogram and is inclined toward the center of the anti-detachment ring 10. The anti-detachment rings 10 form an interlocking groove.

[0042] The auxiliary raised texture 2 extends from bottom to top and extends from one side of the tile body 0 to the other side. The auxiliary raised texture 2 continuously penetrates several of the anti-detachment rings 10.

[0043] The anti-detachment ring 10 refers to the concentric ring-shaped protrusions arranged around the center of the tile body 0, which can be implemented using equally spaced closed rings. The vertical cross-section of the anti-detachment texture 1 is a parallelogram, and this parallelogram is inclined towards the center of the anti-detachment ring 10, making the anti-detachment texture 1 hook-shaped. Therefore, the interlocking groove formed between adjacent anti-detachment rings 10 is also hook-shaped. The hook-shaped interlocking groove facilitates a firm bond between the tile and cement mortar or tile adhesive during tile adhesion, giving the tile a firm and anti-detachment effect. To further explain, since the tile blank has the characteristic of instantaneous expansion when it leaves the mold cavity during the tile manufacturing process, the hook-shaped anti-detachment texture 1 is even more difficult to demold. Therefore, by setting auxiliary textures 2, the originally closed ring-shaped interlocking groove is divided into several smaller interlocking cavities, thereby reducing the difficulty of demolding and preventing damage to the hook-shaped anti-detachment texture 1 during the demolding process.

[0044] The mechanical interlocking strength of the tile back texture structure is enhanced by the barbed anti-detachment ridges 1, while the auxiliary ridges 2 extend through multiple anti-detachment rings 10 to reduce the resistance to tile demolding. The three-dimensional cross-layout of the anti-detachment rings and auxiliary ridges ensures smooth demolding and enhances the interlocking strength between the adhesive layer and the tile through multi-directional interlocking cavities.

[0045] Furthermore, the auxiliary ridge 2 includes a plurality of first auxiliary ridges 21 and a plurality of second auxiliary ridges 22;

[0046] The first auxiliary ridge 21 extends from the lower left corner to the upper right corner of the tile body 0, and several of the first auxiliary ridges 21 are arranged in an array at intervals.

[0047] The second auxiliary ridge 22 extends from the lower right corner to the upper left corner of the tile body 0, and several of the second auxiliary ridges 22 are arranged in an array at intervals.

[0048] The lower left-to-upper right extension configuration means that the extension direction of the first auxiliary ridge 21 forms an angle with the diagonal direction of the tile body. This orientation allows the mold and the blank to separate along an oblique path during demolding. The lower right-to-upper left extension configuration means that the extension direction of the second auxiliary ridge 22 forms a cross-symmetric relationship with the first auxiliary ridge 21. This can be achieved by using a mirror-symmetric tilt angle, and this cross-layout forms a bidirectional guide path. The array-style spacing configuration means that multiple ridges maintain a uniform spacing in their extension direction. This can be achieved by using a parallel arrangement with a spacing of 5mm to 10mm. This spacing provides stress release space for mold separation.

[0049] The two sets of auxiliary convex patterns extend through the anti-detachment ring to form a mesh structure. During demolding, when the mold and the blank separate along an oblique path, the bidirectional intersecting auxiliary convex patterns 2 guide the demolding force to be dispersed in different directions, avoiding edge cracking of the blank caused by stress concentration in one direction. The intersecting auxiliary convex patterns 2 and the anti-detachment ring 10 form a three-dimensional support structure, which disperses shear stress through the oblique path during demolding, preventing the anti-detachment ring from breaking due to uneven stress, while maintaining the integrity of the back pattern structure.

[0050] Furthermore, the anti-detachment ring 10 includes a first bottom surface 104, a first outer surface 101, a first inner surface 102, and a first top surface 103;

[0051] The first bottom surface 104 is connected to the surface of the ceramic tile body 0, and the two ends of the first bottom surface 104 are respectively connected to the bottom end of the first outer side surface 101 and the bottom end of the first inner side surface 102.

[0052] The first outer surface 101 is located on the side of the tile body 0 away from the center, and the first inner surface 102 is located on the side of the tile body 0 closer to the center. The first outer surface 101 and the first inner surface 102 are parallel to each other.

[0053] The first top surface 103 is parallel to the first bottom surface 104, and the two ends of the first top surface 103 are respectively connected to the top of the first outer side surface 101 and the top of the first inner side surface 102.

[0054] The first bottom surface 104 refers to the base portion where the anti-detachment ring 10 connects to the surface of the tile body 0. It can be implemented using a planar structure to evenly transfer the load of the anti-detachment ring 10 to the tile body 0. The first outer surface 101 refers to the side of the anti-detachment ring 10 away from the center. It can be implemented using an inclined plane to form a sliding contact surface with the mold during demolding. The first inner surface 102 refers to the side of the anti-detachment ring 10 closer to the center. It can be implemented using a plane parallel to the first outer surface 101 to form a symmetrical structure and reduce localized stress during demolding. The first top surface 103 refers to the top plane of the anti-detachment ring 10. It can be implemented using a plane parallel to the first bottom surface 104 to maintain the uniformity of the anti-detachment ring's cross-sectional height.

[0055] Specifically, the first bottom surface 104 serves as the supporting foundation for the anti-detachment ring 10, forming a stable support frame by connecting the bottom ends of the first outer side surface 101 and the first inner side surface 102 respectively. The first outer side surface 101 and the first inner side surface 102 adopt a parallel and symmetrical design, which ensures that the anti-detachment ring 10 forms a uniform sliding path with the mold during demolding, avoiding uneven friction distribution caused by the difference in the inclination angle of the two sides. The first top surface 103 is parallel to the first bottom surface 104 and connects the top ends of the first outer side surface 101 and the first inner side surface 102 respectively, constructing an annular protrusion with a constant height, ensuring that the depth of the fitting groove is consistent and preventing shear force caused by sudden height changes during demolding. The sides are connected at the ends to form a closed prism structure, enhancing the overall rigidity of the anti-detachment ring 10 and preventing deformation or breakage during demolding.

[0056] Furthermore, the first outer surface 101 and the first bottom surface 104 form an angle α, where α < 60°.

[0057] Since the first outer surface 101 and the first inner surface 102 are parallel to each other, the angle between the first inner surface 102 and the surface of the tile body 0 is the same as the included angle α. By controlling the included angle α to be less than 60°, the barbed structure of the anti-detachment texture 1 is made stronger. In addition, the interlocking groove with barbed corners can be firmly bonded to adhesives such as cement mortar, achieving the effect of preventing the tile from falling off after it is installed on the wall.

[0058] Furthermore, the distance between the first top surface 103 and the first bottom surface 104 is d1, where 1mm < d1 < 2mm.

[0059] The distance between the first top surface 103 and the first bottom surface 104 of the anti-detachment ring 10 is controlled within the range of 1mm-2mm, so that the fitting groove can form a space to effectively accommodate the adhesive material, while avoiding excessive frictional contact between the side wall of the anti-detachment ring 10 and the mold. When the adhesive material fills the fitting groove, this depth range ensures that the material forms sufficient shear strength after curing. During demolding, the barbed anti-detachment ring 10 (anti-detachment ridge 1) forms an angle with the direction of separation from the mold. Controlling the height of the anti-detachment ring 10 can reduce the contact length of the side wall of the anti-detachment ring 10, thereby reducing the risk of damage to the preform structure caused by demolding resistance.

[0060] Furthermore, the connection between the first top surface 103 and the first outer side surface 101 and the first inner side surface 102 is made by a rounded transition.

[0061] The connection between the first top surface 103 and the first outer surface 101 and the first inner surface 102 adopts an arc-shaped curved surface instead of a sharp corner structure, eliminating the sharp corners at the connection and making the contact surface between the mold and the anti-detachment ring form a continuous and smooth transition. At the same time, the arc structure reduces the micro-mechanical interlocking between the blank and the mold, making the separation process between the blank surface and the mold during demolding smoother, thereby preventing the blank from sticking to the mold or the edges from cracking.

[0062] Furthermore, the auxiliary ridge 2 includes a second bottom surface 201, a second outer surface 202, a second inner surface 203, and a second top surface 204;

[0063] The second bottom surface 201 is connected to the tile body 0, and the two ends of the second bottom surface 201 are respectively connected to the bottom end of the second outer side surface 202 and the bottom end of the second inner side surface 203;

[0064] The second outer surface 202 and the second inner surface 203 are inclined toward each other;

[0065] The second top surface 204 is parallel to the second bottom surface 201, and the two ends of the second top surface 204 are respectively connected to the top of the second outer side surface 202 and the top of the second inner side surface 203.

[0066] The second bottom surface 201 refers to the bearing surface that contacts the auxiliary raised pattern 2 with the surface of the ceramic tile body 0. It can be implemented using a planar structure to disperse the shear stress exerted by the mold on the raised pattern during demolding. The second outer surface 202 and the second inner surface 203 refer to the inclined surfaces that form the sidewalls of the auxiliary raised pattern. They can be implemented using symmetrical inclined surfaces, forming a trapezoidal cross-section structure through opposing inclinations, guiding the mold and raised pattern apart during demolding. The second top surface 204 refers to the planar structure at the top of the auxiliary raised pattern 2. It can be implemented using a plane parallel to the second bottom surface 201 to ensure the uniformity of the contact surface between the adhesive material and the raised pattern during construction.

[0067] Specifically, the second bottom surface 201 serves as the basic support structure for the auxiliary raised pattern 2, forming a stable connection with the tile body 0 during the pressing process, thus avoiding stress concentration at the root of the auxiliary raised pattern. The second outer surface 202 and the second inner surface 203 adopt a symmetrical inclined design, making the vertical cross-section of the auxiliary raised pattern form a trapezoidal structure. During demolding, the contact area between the mold and the outer wall of the auxiliary raised pattern 2 is reduced, thereby reducing friction. The second top surface 204 is set parallel to the second bottom surface 201, providing a flat contact surface for the adhesive material during construction, ensuring uniform adhesive layer thickness, and avoiding local hollowing due to differences in raised pattern height. The two ends of the second top surface 204 are respectively connected to the tops of the second outer surface 202 and the second inner surface 203, forming a closed auxiliary raised pattern contour, preventing edge cracking during demolding.

[0068] Furthermore, the angles between the second outer surface 202 and the second inner surface 203 and the second bottom surface 201 are both β, where β ≤ 60°.

[0069] During demolding, when the angle between the second outer surface 202 and the second inner surface 203 of the auxiliary emboss 2 and the second bottom surface 201 is limited to 60° or less, the inclined shape of the sidewall of the auxiliary emboss 2 can reduce the contact area with the mold sidewall, thereby reducing the frictional resistance between them. Because the inclination angle of the sidewall of the auxiliary emboss 2 is gentle, the mold can slide smoothly along the inclination direction of the sidewall of the auxiliary emboss 2 during separation, avoiding jamming or localized stress concentration between the sidewall and the mold due to an excessively large angle. Simultaneously, the upper limit constraint of the included angle β ensures that the inclination angle of the sidewall of the auxiliary emboss 2 is not too steep, preventing cracks or damage due to insufficient sidewall strength during demolding.

[0070] Furthermore, the distance between the second top surface 204 and the second bottom surface 201 is d2, where d2 < d1.

[0071] d2 refers to the vertical distance between the second top surface and the second bottom surface of the auxiliary emboss, which can be achieved by controlling the recess depth of the mold forming surface. By limiting d2 to be less than d1, the overall height of the auxiliary emboss 2 is lower than that of the anti-detachment emboss 1, thereby preferentially reducing the contact depth between the auxiliary emboss 2 and the mold sidewall during the demolding process.

[0072] Specifically, during the tile demolding process, the separation of the mold from the tile's back pattern generates frictional resistance along the raised sidewalls. When the height of the auxiliary raised pattern 2 is lower than that of the anti-detachment raised pattern 1, the contact area between the auxiliary raised pattern 2 and the mold sidewall is reduced, causing the auxiliary raised pattern 2 to separate from the mold preferentially in the initial stage of demolding. At this time, the anti-detachment raised pattern 1 still maintains contact with the mold, but due to the smaller inclination angle of the sidewalls (first outer surface and second outer surface) of the anti-detachment raised pattern 1, the frictional resistance is more evenly distributed. As the demolding process continues, the anti-detachment raised pattern 1 gradually detaches from the mold, while the auxiliary raised pattern 2 has already completed its separation action. This staged demolding mechanism reduces the instantaneous shear stress experienced by the tile body during demolding, avoiding pattern tearing or edge cracking caused by local resistance concentration.

[0073] Furthermore, the tile body 0 is also provided with an outer edge 01, which surrounds the anti-loosening ridge 1 and the auxiliary ridge 2.

[0074] The outer edge 01 is designed to block cement mortar or tile adhesive and prevent the adhesive from overflowing from the tile when it is squeezed while the tile is being pasted onto the wall.

[0075] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
