Description

Technical Field

[0001] The utility model relates to the technical field of tile production, in particular to a dovetail back pattern tile forming mold core structure. Background Art

[0002] At present, in order to manufacture ceramic tiles with dovetail grooves on the bottom, a mold core consisting of a hard base layer and a soft surface layer (e.g., a polyurethane rubber layer) has appeared, wherein a plurality of columnar protrusions integral with the soft surface layer are arranged on the outer surface of the soft surface layer. For example, a dovetail groove mold for preventing ceramic tiles from falling off is disclosed in the patent document with the Chinese authorization announcement number CN216266663U. When manufacturing ceramic tiles, the powder is compacted through the outer surface of the soft surface layer to form a brick blank. In the process of compacting the powder, the columnar protrusions are compressed and deformed into a dovetail shape, so that a dovetail groove can be formed on the brick blank. Since the shapes of the columnar protrusions on the existing mold core are the same, only the same dovetail grooves can be formed on the tile blank, so when installing the tile, it is impossible to make different areas of the tile produce appropriate grip accordingly; in addition, the columnar protrusions on the mold core are simply evenly arranged, so the formed dovetail grooves are also simply evenly arranged, which can easily lead to different areas of the tile not being able to produce appropriate grip accordingly; thus, it is easy to affect the stability and reliability of the tile installation and positioning, and the existing mold core cannot produce tiles with high reliability. Therefore, it is very necessary to reset the structure of the mold core. Utility Model Content

[0003] The purpose of the utility model is to solve the above-mentioned problems and shortcomings, and to provide a dovetail back pattern tile forming mold core structure, which can form dovetail grooves of appropriate sizes in different areas of the tile, thereby facilitating the generation of appropriate grip in different areas of the tile, thereby facilitating the improvement of the stability and reliability of the tile installation and positioning. The dovetail back pattern tile forming mold core structure can produce tiles with high reliability.

[0004] The technical solution of the utility model is achieved in this way:

[0005] A dovetail back pattern tile forming mold core structure is characterized in that it includes a hard base layer and a soft surface layer stacked together, and two groups of convex strips are arranged integrally with the soft surface layer on the outer surface, and the two groups of convex strips are arranged mirror-symmetrically about the center line of the soft surface layer; the convex strip group includes a plurality of arc-shaped convex strips, each of which is evenly arranged side by side on the soft surface layer along the direction from the middle of the soft surface layer to the end of the soft surface layer, and the two ends of the arc-shaped convex strips are bent in a direction away from the center position of the soft surface layer, and the surface of each arc-shaped convex strip close to the center position of the soft surface layer is an inclined surface inclined toward the end of the soft surface layer, and each arc-shaped convex strip is provided with a convex cone portion on the surface away from the center position of the soft surface layer, and the height A of each convex cone portion gradually increases along the direction from the middle of the soft surface layer to the end of the soft surface layer.

[0007] Preferably, a receiving groove is provided on the outer surface of the soft surface layer, each arc-shaped convex strip is located in the receiving groove, and the arc-shaped convex strip is arranged so as to protrude from the notch of the receiving groove.

[0008] Preferably, the groove wall of the limiting groove is inclined outward and extends to the side wall of the hard base layer, and an inclined portion is provided on the end of the soft surface layer. The inclined portion is attached to the groove wall of the limiting groove and is flush with the groove opening of the limiting groove. The inclined portion encloses a receiving groove.

[0009] Preferably, the outer end width B of the inclined portion is 1.5 mm, the depth C of the receiving groove is 1.2 mm, and the height D of the arc-shaped convex strip is 2 mm.

[0013] Preferably, the middle of each arc-shaped convex strip is located on the center line of the surface layer of the software.

[0020] like Figures 1 to 3As shown, a dovetail back-patterned ceramic tile forming mold core structure described in the utility model comprises a hard base layer 1 and a soft surface layer 2 stacked together, and two groups of convex strip groups 3 are arranged integrally with the soft surface layer 2 on the outer surface thereof, and the two groups of convex strip groups 3 are arranged in mirror symmetry about the center line of the soft surface layer 2; the convex strip group 3 comprises a plurality of arc-shaped convex strips 31, and each arc-shaped convex strip 31 is evenly arranged side by side on the soft surface layer 2 along the direction from the middle of the soft surface layer 2 to the end of the soft surface layer 2, and the two ends of the arc-shaped convex strips 31 are bent in a direction away from the center position of the soft surface layer 2, and the surface of each arc-shaped convex strip 31 close to the center position of the soft surface layer 2 is an inclined surface 32 inclined toward the end direction of the soft surface layer 2, and each arc-shaped convex strip 31 is provided with a convex cone portion 33 on the surface away from the center position of the soft surface layer 2, and the height A of each convex cone portion 33 gradually increases along the direction from the middle of the soft surface layer 2 to the end of the soft surface layer 2.

[0021] In the dovetail back pattern tile forming mold core structure, two convex strip groups 3 arranged in mirror symmetry are arranged on the soft surface layer 2, and the convex strip group 3 includes a plurality of arc-shaped convex strips 31. After the arc-shaped convex strips 31 adopt the above-mentioned arrangement structure, the dovetail back pattern tile forming mold core structure can be very easy to manufacture, so that the manufacturing difficulty of the dovetail back pattern tile forming mold core structure can be very small. By making the surface of each arc-shaped convex strip 31 close to the center of the soft surface layer 2 an inclined surface 32 inclined toward the end of the soft surface layer 2, and respectively setting a convex cone 33 on the surface of each arc-shaped convex strip 31 away from the center of the soft surface layer 2, the height A of each convex cone 33 is gradually increased along the direction from the middle of the soft surface layer 2 to the end of the soft surface layer 2. This can help to make the end of the manufactured tile have a large dovetail groove, which can ensure that the grip strength of the end of the tile is very high, thereby helping to reduce the probability of the tile loosening. Such a dovetail back pattern tile forming mold core structure can form dovetail grooves of appropriate sizes in different areas of the tile, thereby helping to produce appropriate grip in different areas of the tile, and further helping to improve the stability and reliability of the tile installation and positioning. The dovetail back pattern tile forming mold core structure can produce tiles with high reliability.

[0022] like Figure 3 As shown, a limiting groove 11 is provided on the surface of the hard base layer 1, and the soft surface layer 2 is arranged in the limiting groove 11. The limiting groove 11 can limit the soft surface layer 2, which helps to improve the accuracy and stability of the installation and positioning of the soft surface layer 2, thereby helping to further improve the reliability of the dovetail back pattern tile forming mold core structure.

[0023] like Figure 3As shown, a receiving groove 21 is provided on the outer surface of the soft surface layer 2, and each arc-shaped convex strip 31 is located in the receiving groove 21, and the arc-shaped convex strip 31 is arranged to protrude from the notch of the receiving groove 21. This is not only conducive to controlling the material usage of the soft surface layer 2, but also facilitates the arc-shaped convex strip 31 to exert a more stable molding effect, thereby helping to further improve the molding quality of the dovetail groove.

[0024] like Figure 2 and Figure 3 As shown, the groove wall of the limiting groove 11 is inclined outward and extends to the side wall of the hard base layer 1, and the end of the soft surface layer 2 is provided with an inclined portion 22, which is attached to the groove wall of the limiting groove 11 and is flush with the groove opening of the limiting groove 11, and the inclined portion 22 encloses and forms a receiving groove 21. This can make the end of the soft surface layer 2 more stably connected to the hard base layer 1, thereby greatly reducing the probability of the end of the soft surface layer 2 falling off, and further helping to further improve the reliability of the dovetail back pattern tile forming mold core structure.

[0025] like Figure 3 As shown, the outer end width B of the inclined portion 22 is 1.5 mm, the depth C of the receiving groove 21 is 1.2 mm, and the height D of the arc-shaped convex strip 31 is 2 mm. This not only helps to reduce consumables, but also ensures that the installation and positioning of the soft surface layer 2 is very stable and reliable, and enables the arc-shaped convex strip 31 to form a dovetail groove of higher quality.

[0026] like Figure 3 As shown, the angle E between the inclined surface 32 and the bottom of the receiving groove 21 is 135 degrees. This is not only very conducive to expansion molding, but also convenient for the soft surface layer 2 to separate from the brick blank, thereby helping to further improve the molding quality of the dovetail back pattern tile molding mold core structure.

[0027] like Figure 3 As shown, the convex cone portion 33 extends along the outer side of the arc-shaped convex strip 31, the radial cross section of the convex cone portion 33 is triangular, one side wall of the convex cone portion 33 is connected to the side wall of the arc-shaped convex strip 31, and the lower surface of the convex cone portion 33 and the outer end surface of the arc-shaped convex strip 31 are located in the same plane. This not only ensures that the convex cone portion 33 has very high stability and reliability, but also facilitates integrated manufacturing and molding of higher quality dovetail back patterns, which helps to further improve the reliability and applicability of the dovetail back pattern tile molding mold core structure.

[0028] like Figure 3As shown, the other side wall of the convex cone portion 33 forms an arc transition with the bottom of the receiving groove 21, and the arc radius R of the arc transition is 0.5 mm. Such an arc transition can not only improve the connection strength between the arc-shaped convex strip 31 and the bottom of the receiving groove 21, but also help improve the molding quality of the dovetail back pattern.

[0029] like Figure 1 As shown, the middle of each arc-shaped convex strip 31 is located on the center line of the soft surface layer 2. This is conducive to forming a higher quality dovetail pattern, so that each dovetail pattern on the tile can work together to play a more stable and reliable gripping effect, which helps to further improve the applicability of the dovetail pattern tile forming mold core structure.

[0030] like Figure 2 As shown, the thickness F of the hard base layer 1 is 30 mm. In this way, the hard base layer 1 can have a very high structural strength while controlling the amount of material used in the hard base layer 1.

[0031] The hard base layer 1 is a 40CrMoV base layer; the soft surface layer 2, each arc-shaped convex strip 31, each convex cone portion 33 and the inclined portion 22 are an integral polyurethane structure, and their hardness is 94±1HV.

[0032] like Figure 4 As shown, the dovetail back pattern ceramic tile forming mold core structure of the utility model can be used to produce 300×600 ceramic tiles, and the maximum value of the height A is less than or equal to 0.6mm. The dovetail back pattern ceramic tile forming mold core structure can form a single-sided dovetail effect on the brick blank 10. When the press is in motion, the upper and lower molds rise at the same time, and the brick blank 10 expands immediately after leaving the mold cavity due to the lack of resistance. After the brick blank 10 has expanded completely, the upper mold can rise and leave the brick blank 10, which is conducive to forming high-quality dovetail back pattern ceramic tiles.
