[0002] In recent years, large-scale ceramic tiles have become a popular trend. The market has seen the emergence of finished ceramic slabs with finished specifications of 1620*2400 or even 1800*3200. Since large ceramic slabs need to go through processes such as edge grinding, firing and trimming before they can be finished, the size of the bricks of large ceramic slabs is large, and the required forming molds are larger. Large-scale molds have low rigidity and are easily damaged by frequent and large lifting and lowering. Therefore, existing ceramic presses use a square movable beam with a shorter stroke to reduce the lifting range of the mold, thereby protecting the mold. However, the problem is that the space between the upper mold and the lower mold is small, there is not enough space to place the mold frame, and it is difficult to replace the mold core, which makes the production line single and is not conducive to the production of large ceramic slabs of different specifications and models.

DETAILED DESCRIPTION

[0027] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0028] Reference Figure 1-7 A forming die for large ceramic tiles, applied to a ceramic press, comprises an upper die assembly 1 and a lower die 2, specifically, as Figure 7As shown, the ceramic press has a movable beam 4, the upper mold assembly 1 is arranged at the bottom of the movable beam 4, the upper mold assembly 1 is arranged opposite to the lower mold 2, the lower mold 2 is arranged below the upper mold assembly 1, and the movable beam 4 is used to drive the upper mold assembly 1 to press down and rise, so that the upper mold assembly 1 moves downward relative to the lower mold 2 to press the powder between the lower mold 2 and the upper mold assembly 1, and moves upward relative to the lower mold 2 to release the pressed embryo. The upper mold assembly 1 includes a mold base 11 and a mold core 12, the mold base 11 is installed on the bottom end surface of the movable beam 4, the mold base 11 has an adsorption mechanism 111, the mold base 11 adsorbs the mold core 12 on the bottom end surface of the mold base 11 through the adsorption mechanism 111, and the bottom end surface of the mold core 12 is provided with a powder blocking edge 121 for preventing the powder from flying out. A sliding mechanism 3 is provided between the mold core 12 and the lower mold 2. When installing or removing the mold core 12, the mold core 12 slides relative to the lower mold 2 to enter the lower part of the mold base 11, or slides relative to the lower mold 2 to move out from the lower part of the mold base 11. Specifically, when installing the mold core 12, the mold core 12 slides relative to the lower mold 2 to enter the lower part of the mold base 11, and the adsorption mechanism 111 adsorbs the mold core 12 on the bottom end surface of the mold base 11, wherein the adsorption mechanism 111 can be a vacuum adsorption mechanism or an electromagnetic adsorption mechanism. When removing the mold core 12, the adsorption mechanism 111 releases the mold core 12 to separate the mold core 12 from the mold base 11, and then slides relative to the lower mold 2 to move the mold core 12 out from the lower part of the mold base 11.

[0029] In the present invention, a powder blocking edge 121 is provided on the bottom end surface of the mold core 12, and the powder blocking edge 121 blocks the powder from flying out, replacing the mold frame in the traditional mold, which is conducive to reducing the distance between the upper mold assembly 1 and the upper mold. When producing ceramic slabs of different specifications, only the mold core 12 needs to be replaced, avoiding the need to replace the mold frame while replacing the mold core 12, and the adjustment is convenient and quick.

[0030] By arranging the sliding mechanism 3 between the mold core 12 and the lower mold 2, the mold core 12 can slide into the bottom of the mold base 11 relative to the lower mold 2, or slide out from the bottom of the mold base 11 relative to the lower mold 2. The mold core 12 can be disassembled and assembled in a sliding manner, which facilitates the mold core 12 to enter and exit the space with restricted height, thereby facilitating the disassembly and assembly of the mold core 12.

[0031] Furthermore, the sliding mechanism 3 includes a sliding member 31 and a sliding rail 32, wherein the sliding member 31 is detachably mounted on both sides of the mold core 12, and the sliding rail 32 is mounted on both sides of the lower mold 2. Figure 2As shown, through the sliding cooperation between the sliding member 31 and the sliding rail 32, the mold core 12 can slide into the bottom of the mold base 11 relative to the lower mold 2, or can slide out from the bottom of the mold base 11 relative to the lower mold 2. Specifically, the sliding member 31 is installed on both sides of the mold core 12 in a detachable connection manner. When installing the mold core 12, after the mold core 12 slides to the bottom of the mold base 11, the mold core 12 removes the sliding member 31, which not only prevents the sliding member 31 from affecting the mold core 12 in pressing the brick embryo, but also reduces the weight of the mold core 12. When disassembling the mold core 12, the sliding member 31 is reinstalled on both sides of the mold core 12, so that the mold core 12 can slide out of the mold base 11 relative to the lower mold 2. Among them, the sliding member 31 can be a roller or a slider.

[0032] Further, the mold core 12 is provided with a mounting seat 122 for mounting the sliding member 31, the mounting seat 122 has a fixing portion 1221 and a mounting portion 1222, the fixing portion 1221 extends outward in the horizontal direction, one end of the fixing portion 1221 is connected to the side wall of the mold core 12, the mounting portion 1222 is detachably arranged at the other end of the fixing portion 1221, and the sliding member 31 is detachably connected to the mounting portion 1222 via a threaded fixing member. Specifically, as Figure 4 As shown, the mold core 12 is square, and the mounting seats 122 are arranged at the four corners of the mold core 12, the fixing portion 1221 extends outward in the horizontal direction, and the mounting portion 1222 is detachably connected to the fixing portion 1221 through threaded fixings such as studs or screws, so that the mounting portion 1222 is arranged on the side of the mold core 12, which facilitates the installation of the sliding member 31 on both sides of the mold core 12 and avoids increasing the overall height of the mold core 12. Among them, the sliding member 31 is detachably connected to the mounting portion 1222 through threaded fixings such as studs or screws, which facilitates the disassembly and assembly of the sliding member 31.

[0033] Furthermore, the sliding member 31 is a round rod, the cross section of the slide rail 32 is V-shaped, the sliding member 31 is provided with a mounting threaded hole 311 that matches the mounting portion 1222, and the two ends of the sliding member 31 are respectively mounted on the two mounting portions 1222 on the same side. Figure 2 As shown, the sliding member 31 is a round rod, and the cross section of the slide rail 32 is V-shaped. The round rod moves in the arc groove along the axial direction to achieve the sliding cooperation between the mold core 12 and the lower mold 2. The round rod is selected as the sliding member 31, which has a small contact area and small friction resistance, and can reduce the increment of the overall height of the mold core 12. It also has a simple structure, reduces the use of spare parts, and reduces the cost of the mold. Specifically, as Figure 4As shown, the two ends of the sliding member 31 are respectively installed on the two mounting parts 1222 on the same side, and threaded fixing parts such as studs or screws pass through the mounting parts 1222 and are threadedly engaged with the mounting threaded holes 311, so that the sliding member 31 can be detachably fixed on both sides of the mold core 12.

[0034] Furthermore, the mold base 11 includes a magnetic base 112 and a magnetic plate 113, and the adsorption mechanism 111 includes a first electromagnetic coil 1111 and a second electromagnetic coil 1112. A plurality of the first electromagnetic coils 1111 are arranged on the top surface of the magnetic base 112, and when the first electromagnetic coils 1111 are energized, the magnetic base 112 is adsorbed on the bottom of the movable beam 4 of the ceramic press. The magnetic plate 113 is installed on the bottom surface of the magnetic base 112, and a plurality of the second electromagnetic coils 1112 are arranged on the bottom surface of the magnetic plate 113, and when the second electromagnetic coils 1112 are energized, the mold core 12 is adsorbed on the bottom of the magnetic plate 113. Specifically, refer to Figure 1 , 3 As shown in FIG. 7 , by arranging a plurality of the first electromagnetic coils 1111 on the top surface of the magnetic base 112, when the first electromagnetic coils 1111 are energized, the magnetic base 112 is adsorbed on the bottom of the movable beam 4 of the ceramic press, so that the mold base 11 is installed on the bottom of the movable beam 4 of the ceramic press. By arranging the second electromagnetic coils 1112 on the bottom surface of the magnetic plate 113, when the second electromagnetic coils 1112 are energized, the magnetic plate 113 adsorbs the mold core 12, so that the mold core 12 and the mold base 11 are detachably connected.

[0035] Furthermore, the magnetic plate 113 is provided with a locking seat 1131. When the mold core 12 is adsorbed on the bottom of the magnetic plate 113, the locking seat 1131 and the mounting portion 1222 are locked by a threaded fastener. Figure 5 As shown, the magnetic plate 113 is square, and the locking seats 1131 are arranged at the four corners of the magnetic plate 113. When the mold core 12 is adsorbed on the bottom of the magnetic plate 113, the mounting portion 1222 is first separated from the sliding member 31, and then the height position of the mounting portion 1222 connected to the fixing portion 1221 is adjusted to make the mounting portion 1222 fit with the locking seat 1131, and then fixedly connected by threaded fixings such as studs or screws, so that the mounting portion 1222 is connected to both the fixing portion 1221 and the locking seat 1131, thereby locking the mold core 12 and the magnetic plate 113 to prevent the mold core 12 from falling.

[0036] Furthermore, the magnetic base 112 is locked with the bottom of the movable beam 4 of the ceramic press by means of a threaded fastener, and the magnetic base 112 is provided with a plurality of locking through holes 1121 distributed linearly. Figure 6 As shown, the magnetic base 112 is provided with a plurality of locking through holes 1121, and threaded fasteners such as studs or screws are passed through the locking through holes 1121 to connect with the ceramic press, thereby achieving locking between the magnetic base 112 and the movable beam 4 of the ceramic press to prevent the magnetic base 112 from falling. Among them, the plurality of locking threaded holes are linearly distributed, which is conducive to stress dispersion.

[0037] Furthermore, the magnetic base 112 and the magnetic plate 113 are detachably connected via a threaded fastener, and the magnetic base 112 and the magnetic plate 113 are respectively provided with corresponding connection threaded holes 114. Figure 5 and Figure 6 By setting a plurality of corresponding connecting threaded holes 114 on the magnetic base 112 and the magnetic plate 113, the magnetic base 112 and the magnetic plate 113 can be connected through threaded fasteners such as studs or screws, thereby realizing a detachable connection between the magnetic base 112 and the magnetic plate 113, which is convenient for disassembly and maintenance.

[0038] Furthermore, the powder-blocking edge 121 includes a rubber sleeve and an elastic material, the elastic material fills the interior of the rubber sleeve, and the edge where the rubber sleeve abuts against the powder is a bevel edge 1211. Specifically, Figure 1 As shown, in this embodiment, the cross section of the powder retaining edge 121 is triangular, and the elastic material fills the inside of the rubber sleeve. By setting the edge of the rubber sleeve against the powder as a bevel 1211, the contact area between the edge powder and the powder retaining edge 121 is increased, so as to avoid stress concentration at the edge of the brick embryo causing the brick embryo to break, thereby ensuring the integrity of the brick embryo. The elastic material can be sponge or rubber.

[0039] Furthermore, the bottom end surface of the mold core 12 is provided with a protrusion 123. Specifically, Figure 1 As shown, in this embodiment, the protrusion 123 is provided on the bottom end surface of the mold core 12 so that the brick blank is formed during the pressing process.
