Through the cooperation of a lifting screw and a threaded sleeve, the lifting plate and four sets of first guide rods connected to the lifting plate can be raised and lowered, thereby raising and lowering the lower pressing mold. During the raising and lowering of the lower pressing mold, the relative position of the mold cavity and the top blocks changes, allowing for flexible adjustment of the mold cavity depth. When the mold cavity depth changes, the lifting mechanism, along with the upper pressing mold and pressure block, compresses the raw material within the mold cavity, producing microcrystalline wear-resistant bricks of different thicknesses. This breaks the limitation of traditional brick presses that can only process bricks of specific thicknesses, significantly expanding the equipment's application range and meeting the diverse needs for microcrystalline wear-resistant brick thickness in different scenarios.

[0013] To ensure the quality of pressed brick forming and improve production stability: The lifting mechanism drives the upper pressing mold to rise and fall stably, ensuring that multiple sets of pressing blocks can accurately and stably cooperate with multiple sets of mold cavities. This applies uniform and stable pressure to the raw materials within the mold cavities, avoiding poor brick forming quality due to uneven pressure or misalignment of the pressing blocks. Simultaneously, the leveling mechanism automatically levels the raw materials, ensuring uniform distribution within the mold cavities and further guaranteeing the quality of subsequent pressed brick forming. Furthermore, the sliding cooperation of multiple sets of support columns and sliding holes, and the sliding cooperation of four sets of first guide rods and four sets of guide holes in the adjustment mechanism ensure that the lower pressing mold remains stable during the lifting and adjustment process, avoiding deviation or shaking. This provides strong support for the stability of the entire pressed brick production process, contributing to improved consistency and reliability of microcrystalline wear-resistant brick production quality.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0017] Please see Figures 1-4 A microcrystalline wear-resistant brick production pressing device includes an upper pressing mold 1 and a lower pressing mold 2. The lower pressing mold 1 has multiple sets of pressing blocks 3 at its bottom, and the lower pressing mold 2 has multiple sets of mold cavities 4 at its top. The device also includes: The installation platform 5 includes a smoothing mechanism, an adjustment mechanism, and a lifting mechanism. The lifting mechanism is installed at the top of the installation platform 5 and is used to drive the upper pressing mold 1 to rise and fall. Through the cooperation of multiple sets of pressing blocks 3 and multiple sets of mold cavities 4, the raw material in the mold cavity 4 is compressed into bricks. The smoothing mechanism is installed at the rear end of the lower pressing mold 2 and is used to smooth the brick raw material located at the top of the lower pressing mold 2. The lower pressing mold 2 is installed at the top of the installation platform 5 through the adjustment mechanism. By adjusting the height of the lower pressing mold 2, the depth of the mold cavity 4 can be adjusted, thereby compressing bricks of different thicknesses. The adjustment mechanism includes multiple sets of top blocks 6, multiple sets of support columns 7, four sets of first guide rods 8, lifting plates 9, lifting screws 10, and threaded sleeves 11. Multiple sets of sliding holes 12 are respectively provided at the bottom of the multiple sets of mold cavities 4. The outer walls of the multiple sets of support columns 7 are slidably connected to the multiple sets of sliding holes 12. The bottom ends of the multiple sets of support columns 7 are all connected to the top of the mounting platform 5. The top ends of the multiple sets of support columns 7 are respectively connected to the bottom ends of the multiple sets of top blocks 6. The four side walls of the multiple sets of top blocks 6 are slidably connected to the multiple sets of mold cavities 4. The multiple sets of top blocks 6 are respectively located in the multiple sets of mold cavities 4. Inside cavity 4, the top ends of four sets of first guide rods 8 are connected to the bottom end of the pressing mold 2. The mounting platform 5 is provided with a working cavity 13. The top end of the working cavity 13 is provided with four sets of guide holes. The four sets of first guide rods 8 are slidably connected to the four sets of guide holes respectively. The bottom ends of the four sets of first guide rods 8 are connected to the top end of the lifting plate 9. The top and bottom ends of the lifting screw 10 are rotatably connected to the top and bottom ends of the working cavity 13 respectively. The threaded sleeve 11 is connected to the middle position of the lifting plate 9. The inner side wall of the threaded sleeve 11 is connected to the lifting screw 10. To solve the problem of manual leveling and improve production efficiency and safety, this equipment automatically levels the brick material located at the top of the lower mold 2 by installing a leveling mechanism at the rear end of the lower mold 2. No manual operation is required, eliminating the tedious manual leveling process, significantly reducing manpower and time consumption, and substantially improving the overall efficiency of the microcrystalline wear-resistant brick production process. Furthermore, workers do not need to approach the mold cavity 4 area of ​​the brick pressing equipment, effectively avoiding safety risks such as squeezing and collisions that may occur due to improper equipment operation or handling, greatly ensuring the personal safety of workers.

[0018] This equipment achieves flexible adjustment of brick thickness, expanding its application range. The lower pressing mold 2 is mounted on the top of the mounting platform 5 via an adjustment mechanism. Multiple sets of top blocks 6 in the adjustment mechanism are slidably connected to multiple sets of mold cavities 4. Through the cooperation of the lifting screw 10 and the threaded sleeve 11, the lifting plate 9 and four sets of first guide rods 8 connected to the lifting plate 9 can be raised and lowered, thereby raising and lowering the lower pressing mold 2. During the raising and lowering of the lower pressing mold 2, the relative position of the mold cavity 4 and the top blocks 6 changes, achieving flexible adjustment of the mold cavity 4 depth. When the mold cavity 4 depth changes, in conjunction with the lifting mechanism, the upper pressing mold 1 and the pressure block 3 compress the raw material inside the mold cavity 4, producing microcrystalline wear-resistant bricks of different thicknesses. This breaks the limitation of traditional brick presses that can only process bricks of specific thicknesses, significantly expanding the equipment's application range and meeting the diverse needs for microcrystalline wear-resistant brick thickness in different scenarios.

[0019] To ensure the quality of pressed brick forming and improve production stability: The lifting mechanism drives the upper pressing mold 1 to rise and fall stably, ensuring that multiple sets of pressing blocks 3 can accurately and stably cooperate with multiple sets of mold cavities 4, applying uniform and stable pressure to the raw materials in the mold cavities 4, avoiding poor brick forming quality due to uneven pressure or misalignment of the pressing blocks 3. At the same time, the leveling mechanism automatically levels the raw materials, ensuring uniform distribution of raw materials in the mold cavities 4, further guaranteeing the quality of subsequent pressed brick forming. In addition, the sliding cooperation of multiple sets of support columns 7 and multiple sets of sliding holes 12, and the sliding cooperation of four sets of first guide rods 8 and four sets of guide holes in the adjustment mechanism ensure that the lower pressing mold 2 remains stable during the lifting and adjustment process, avoiding deviation, shaking, etc., providing strong support for the stability of the entire pressed brick production process, and helping to improve the consistency and reliability of microcrystalline wear-resistant brick production quality.

[0020] Please see Figures 1-4 The smoothing mechanism includes a mounting plate 14, an electric cylinder 15, two sets of sleeves 16, two sets of sliding rods 17, and a smoothing plate 18. The mounting plate 14 is connected to the rear end of the pressing mold 2. The electric cylinder 15 and the two sets of sleeves 16 are both connected to the top end of the mounting plate 14. The output end of the electric cylinder 15 is connected to the rear end of the smoothing plate 18. The two sets of sliding rods 17 are respectively fitted into the two sets of sleeves 16. The front ends of the two sets of sliding rods 17 are connected to the rear end of the smoothing plate 18. The bottom end of the smoothing plate 18 slides and fits against the top end of the pressing mold 2. Using an electric cylinder 15 as the power source, compared with the traditional manual or simple drive method, the output thrust is uniform and controllable, which can drive the squeegee 18 to slide along the top of the pressing mold 2 at a stable speed, avoiding material accumulation or incomplete scraping caused by power fluctuations, ensuring that the material thickness in the mold cavity 4 is consistent, solving the problem of "low efficiency and poor effect of manual squeegee", and further shortening the production cycle of a single brick; the sliding cooperation of the two sets of sleeves 16 and the slide rod 17 provides bidirectional guidance and limit for the squeegee 18, ensuring that the squeegee 18 always remains parallel and in contact with the top of the pressing mold 2, avoiding mold edge wear or material leakage caused by the squeegee 18 shifting, which not only extends the service life of the squeegee 18 and the pressing mold 2, but also reduces material waste and improves production economy.

[0021] Please see Figures 1-4 The lifting mechanism includes a mounting frame 19, a hydraulic cylinder 20, and two sets of second guide rods 21. The mounting frame 19 is connected to the top of the mounting platform 5, the hydraulic cylinder 20 is connected to the top of the mounting frame 19, the bottom of the hydraulic cylinder 20 is connected to the top of the upper pressing mold 1, the bottom of the two sets of second guide rods 21 is connected to the top of the upper pressing mold 1, and the two sets of second guide rods 21 are slidably connected to the mounting frame 19. Using a hydraulic cylinder 20 as the lifting power, the output pressure is much greater than that of a regular air cylinder or motor 22, which can provide uniform and sufficient downward pressure to the upper pressing mold 1, ensuring that the compression strength of the raw material in the mold cavity 4 by the pressing block 3 meets the standard, avoiding the problem of loose bricks and easy breakage caused by insufficient pressure, solving the potential hidden danger of "poor brick forming quality" in the background technology, and improving the structural strength and wear resistance of microcrystalline wear-resistant bricks; the sliding cooperation between the two sets of second guide rods 21 and the mounting frame 19 limits the lateral displacement of the upper pressing mold 1 during the lifting process, ensuring that multiple sets of pressing blocks 3 can be accurately aligned with multiple sets of mold cavities 4, avoiding the edge collision of mold cavity 4 or brick forming displacement caused by misalignment of pressing blocks 3, further ensuring the consistency of brick forming and reducing the defect rate.

[0022] Please see Figures 1-4 It also includes a motor 22, a drive shaft 23 and two sets of bevel gears 24. The motor 22 is connected to the bottom end of the working chamber 13, the drive shaft 23 is connected to the output end of the motor 22, and the two sets of bevel gears 24 are respectively connected to the drive shaft 23 and the lifting screw 10. The two sets of bevel gears 24 are meshed together. The motor 22 drives the lifting screw 10 instead of manually rotating it, eliminating the need for staff to enter under the equipment or operate the adjustment components at close range. Simply controlling the start and stop of the motor 22 is sufficient to raise and lower the pressing mold 2, completely solving the problems of "time-consuming, labor-intensive, and inefficient" traditional manual adjustment. The motor 22 outputs a stable speed, and with the precise transmission of the drive shaft 23 and bevel gear 24, it can drive the lifting screw 10 to rotate at a uniform speed, enabling the pressing mold 2 to rise and fall with millimeter-level precision. Compared with manual adjustment, this significantly improves the dimensional accuracy of bricks of different thicknesses, meeting the stringent requirements for brick thickness in high-end scenarios.

[0023] Please see Figures 1-4 It also includes four sets of reinforcing ribs 25, which are symmetrically connected to the bottom end of the lifting plate 9, and the inner ends of the four sets of reinforcing ribs 25 are connected to the outer wall of the threaded sleeve 11. The supporting effect of the reinforcing rib 25 makes the connection between the threaded sleeve 11 and the lifting plate 9 more stable. When the lifting screw 10 rotates and drives the threaded sleeve 11 to rise and fall, it can reduce the radial sway of the threaded sleeve 11, thereby ensuring that the four sets of first guide rods 8 slide smoothly along the guide hole, avoiding the displacement or swaying of the lower mold 2 during the lifting process, further ensuring the accuracy of the depth adjustment of the mold cavity 4, and indirectly improving the brick forming quality. The reinforcing rib 25 adopts a "symmetrical distribution + thin wall design", which improves the structural strength without significantly increasing the overall weight of the lifting plate 9, avoiding the increase in load on the motor 22 or the accelerated wear of the lifting screw 10 due to the extra weight, thus taking into account both structural stability and equipment operating efficiency.

[0024] Please see Figures 1-4 A rubber pad 26 is provided at the bottom of the smearing plate 18, and the rubber pad 26 slides and fits against the top of the pressing mold 2. The rubber pad 26 has a certain degree of elasticity, allowing it to fit tightly against the tiny uneven surfaces at the top of the pressing mold 2. This prevents material residue from remaining between the traditional rigid trowel plate 18 and the mold due to gaps. During the sliding process of the trowel plate 18, the rubber pad 26 prevents direct friction between the metal material of the trowel plate 18 and the top of the pressing mold 2, preventing scratches or wear on the mold surface and extending the service life of the pressing mold 2. It also reduces the amount of debris generated by metal friction mixed into the raw materials, preventing impurities and defects in the brick. The elasticity of the rubber pad 26 absorbs the impact force during the sliding of the trowel plate 18, reducing noise from metal-to-metal collisions, improving the workshop working environment, meeting the "low noise" environmental protection requirements of modern industrial production, and enhancing the comfort of operators.

[0025] In summary, when using this microcrystalline wear-resistant brick production pressing equipment, turn on the power and check whether the lifting mechanism, smoothing mechanism, and adjusting mechanism are in their initial states: the upper pressing mold 1 is in its highest position under the action of the lifting mechanism, with the pressing block 3 far away from the mold cavity 4; the lower pressing mold 2 is at its preset initial height under the support of the adjusting mechanism, with the depth of the mold cavity 4 corresponding to the thickness of a conventional brick; and the smoothing plate 18 of the smoothing mechanism is at the rear end of the lower pressing mold 2 without obstructing the opening of the mold cavity 4. The operator evenly feeds the microcrystalline wear-resistant brick raw materials, such as a mixture of fly ash and coal gangue, into the multiple sets of mold cavities 4 at the top of the lower pressing mold 2, with the amount of raw materials slightly exceeding the volume of the mold cavity 4 to allow for compression space.

[0026] The power unit of the smoothing mechanism is activated, driving the smoothing plate 18 to slide forward along the top of the lower pressing mold 2. The bottom end of the smoothing plate 18 is in close contact with the top of the lower pressing mold 2. During the sliding process, excess material in the mold cavity 4 is scraped off. The scraped material can be recycled and reused. At the same time, the material in the mold cavity 4 is compacted and flattened to ensure that the material thickness in each mold cavity 4 is consistent. After the automatic smoothing is completed, the smoothing plate 18 is driven by the electric cylinder 15 to retract to the rear end of the lower pressing mold 2, waiting for the next operation.

[0027] To produce bricks of different thicknesses, the motor 22 is powered on and started. The motor 22 drives the drive shaft 23 to rotate. The drive shaft 23 is driven by two sets of bevel gears 24, which in turn drive the lifting screw 10 to rotate at a constant speed within the working chamber 13. The lifting screw 10 engages with the threaded sleeve 11 for threaded transmission, causing the lifting plate 9 connected to the threaded sleeve 11 to rise and fall. The lifting plate 9 slides along the guide holes of the mounting platform 5 via four sets of first guide rods 8, causing the lower pressing mold 2 to rise and fall synchronously. Simultaneously, multiple sets of sliding holes 12 of the lower pressing mold 2 slide along multiple sets of support columns 7, and multiple sets of top blocks 6 slide synchronously relative to each other within the mold cavity 4. The depth of the mold cavity 4 changes with the rise and fall of the lower pressing mold 2. When the lower pressing mold 2 rises, the depth of the mold cavity 4 decreases, corresponding to the production of thin bricks; when the lower pressing mold 2 falls, the depth of the mold cavity 4 increases, corresponding to the production of thick bricks. After adjustment, the motor 22 is turned off, and the adjustment mechanism locks the position of the lower pressing mold 2 to ensure the stability of the depth of the mold cavity 4.

[0028] The hydraulic cylinder 20 of the lifting mechanism is activated, pushing the upper pressing mold 1 to descend at a constant speed along the second guide rod 21. The multiple sets of pressure blocks 3 at the bottom of the upper pressing mold 1 are precisely aligned with the multiple sets of mold cavities 4 of the lower pressing mold 2. As the upper pressing mold 1 continues to descend, the pressure blocks 3 extend into the mold cavities 4, applying uniform pressure to the smoothed raw material. The pressure is preset according to the thickness of the brick, compressing the raw material to the preset thickness and maintaining pressure to ensure that the brick is formed stably.

[0029] After the brick pressing is completed, the lifting mechanism drives the upper pressing mold 1 to rise and the reset pressing block 3 to disengage from the mold cavity 4. The workers or the matching brick removal mechanism take out the formed microcrystalline wear-resistant bricks from the mold cavity 4, completing the single batch production.

[0030] The electric cylinder 15, motor 22, and hydraulic cylinder 20 are commercially available devices known to those skilled in the art. We are simply using them here without making any structural or functional improvements, so we will not go into detail here. The electric cylinder 15, motor 22, and hydraulic cylinder 20 are equipped with matching control switches. The installation position of the control switches is selected according to actual usage requirements to facilitate operation and control by the operator.

[0031] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
