Description

Technical Field

[0001] This utility model relates to the field of brick-making mold technology, and specifically discloses an adjustable brick-making mold platform. Background Technology

[0002] Bricks are a widely used basic material in the construction industry. They are mainly made from clay, fly ash, concrete, and other raw materials through molding and firing (or curing). They possess good load-bearing, heat insulation, and sound insulation properties and are commonly used in wall construction, road paving, and structure building. In small-scale brick production, raw materials are often pressed into shape using brick-making molds. The structural design of the molds directly affects the dimensional accuracy, density, and production efficiency of the bricks. Small-scale brick-making equipment, due to its small size and relatively simple operation, is suitable for rural building material processing and temporary brick-making at construction sites.

[0003] In the existing technology, there is a small brick making machine. In the initial state, the lower end of the mold is directly attached to the ground. The operator needs to fill the brick making raw material into the forming groove of the mold and press it by moving the pressure plate downward. After pressing, the pressure plate returns to its original position. At this time, the operator needs to manually push the pusher to move the mold as a whole upward through the linkage mechanism, so that the mold separates from the formed brick and demolds it, leaving the brick on the ground.

[0004] While the aforementioned device has a simple structure, it suffers from several drawbacks: Firstly, after demolding, the bricks fall directly to the ground. The lack of a liftable support platform makes it difficult to quickly transport the bricks to designated storage or transport areas using forklifts, pallets, or other tools, increasing manual handling costs. Secondly, the demolding process relies on manually pushing the push rod, requiring continuous external force. Prolonged operation can easily lead to operator fatigue and affect production efficiency. Therefore, an adjustable brick-making mold platform is needed to solve these problems. Summary of the Invention

[0005] This utility model proposes an adjustable brick-making mold platform. By setting up a liftable support platform and opening forklift slots on the pallet, the demolded bricks can be quickly transferred to a designated area by forklift along with the pallet, effectively reducing manual handling costs. At the same time, the demolding process can be automatically realized, replacing the traditional manual push rod operation, reducing the physical exertion of operators, and significantly improving production efficiency.

[0006] This utility model is implemented as follows: an adjustable brick-making mold platform includes a frame, a template with multiple forming grooves is provided inside the frame, an adjustment mechanism is provided on the lower side of the template, and a pressing mechanism is provided on the upper side of the template. The adjustment mechanism includes a fixed plate fixedly connected inside the frame. A lead screw is rotatably connected to the upper end of the fixed plate. A connecting plate is threaded to the outer wall of the lead screw. A cylinder is fixedly connected to the upper end of the connecting plate. A lifting platform is provided above the cylinder. A first pressure sensor is fixedly connected between the cylinder and the lifting platform. A support plate that fits against the lower end face of the template is placed on the upper end of the lifting platform. Two forklift slots are provided at the lower end of the support plate. The adjustment mechanism also includes a drive mechanism. The pressing mechanism includes a hydraulic cylinder installed on the upper end of the frame, a sliding plate is provided inside the frame, the output end of the hydraulic cylinder passes through the upper end of the frame and is fixedly connected to a second pressure sensor between the hydraulic cylinder and the sliding plate, and multiple pressing blocks are fixedly connected to the lower end of the sliding plate.

[0007] As a preferred embodiment of the adjustable brick-making mold platform of this utility model, the driving mechanism includes a frame fixedly connected to the lower end of a fixed plate, a partition fixedly connected inside the frame, a worm gear rotatably connected between the left end of the partition and the left side of the inner wall of the frame, a worm wheel meshing with the outer wall of the worm gear, a transmission shaft fixedly connected between the worm wheel and the lead screw, and a servo motor with its output end fixedly connected to the worm gear installed at the right end of the partition.

[0008] As a preferred embodiment of the adjustable brick-making mold platform of this utility model, the upper end of the lifting platform is fixedly connected to a U-shaped positioning frame.

[0009] As a preferred platform for an adjustable brick-making mold according to this utility model, the right end of the frame is equipped with an operation panel and a controller.

[0010] As a preferred platform for an adjustable brick-making mold of this utility model, the left and right ends of the inner wall of the frame are provided with first sliding grooves, and the interior of the two first sliding grooves is slidably connected with a first slider that is fixedly connected to the sliding plate. The inner wall of the frame is provided with a second sliding groove at both the left and right ends, and a second slider that is fixedly connected to the lifting platform is slidably connected inside the two second sliding grooves.

[0011] As a preferred embodiment of the adjustable brick-making mold platform of this utility model, the outer wall of the cylinder is fixedly connected to a connecting ring, and the outer wall of the connecting ring is slidably connected to two anti-torsion rods that are fixedly connected to the lifting platform.

[0012] As a preferred platform for an adjustable brick-making mold according to this utility model, the frame has mounting plates with multiple mounting holes fixedly connected to both the left and right ends.

[0013] The beneficial effects of this utility model are: 1. In use, the pallet is positioned on the upper part of the lifting platform. The drive mechanism rotates the lead screw, causing the lifting platform and pallet to rise synchronously until the upper surface of the pallet contacts the lower surface of the template. At this point, the first pressure sensor monitors the contact pressure, and the controller stops the servo motor at the preset pressure, allowing the pallet to stably support the template. Then, the raw material is filled into the forming groove of the template. The hydraulic cylinder pushes the sliding plate and pressing block downwards to pressurize the raw material. The second pressure sensor provides real-time feedback on the pressing force. After reaching the preset pressure, the controller controls the hydraulic cylinder to hold the pressure for a set time to ensure the brick is densely formed. After pressing, the hydraulic cylinder resets. When demolding is required, the drive mechanism rotates the lead screw in the opposite direction, causing the connecting plate, lifting platform, and pallet to descend synchronously. The template is held stationary by the frame and connecting block, allowing the brick in the forming groove to separate from the template as the pallet descends. This automatically completes the demolding process, replacing traditional manual push-rod operation, reducing operator fatigue, and significantly improving production efficiency.

[0014] 2. After demolding, the operator inserts the forklift forks into the forklift slot at the bottom of the pallet from the front side of the frame, and uses the forklift to lift the pallet and the molded bricks on it as a whole, and transfers them to the designated storage area. By setting up a liftable carrying platform and opening forklift slots on the pallet, the demolded bricks can be quickly transferred to the designated area by forklift along with the pallet, effectively reducing the cost of manual handling.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0019] Please see Figure 1-4 An adjustable brick-making mold platform includes a frame 1, a template 2 with multiple forming grooves 3 inside the frame 1, an adjustment mechanism on the lower side of the template 2, and a pressing mechanism on the upper side of the template 2. The adjustment mechanism includes a fixed plate 12 fixedly connected inside the frame 1. A lead screw 13 is rotatably connected to the upper end of the fixed plate 12. A connecting plate 14 is threadedly connected to the outer wall of the lead screw 13. A cylinder 15 is fixedly connected to the upper end of the connecting plate 14. A lifting platform 8 is provided above the cylinder 15. A first pressure sensor 16 is fixedly connected between the cylinder 15 and the lifting platform 8. A support plate 9 that fits against the lower end face of the template 2 is placed on the upper end of the lifting platform 8. Two forklift slots 11 are opened at the lower end of the support plate 9. The adjustment mechanism also includes a drive mechanism. The pressing mechanism includes a hydraulic cylinder 4 installed on the upper end of the frame 1. A sliding plate 5 is provided inside the frame 1. The output end of the hydraulic cylinder 4 passes through the upper end of the frame 1 and is fixedly connected to the sliding plate 5 with a second pressure sensor 6. Multiple pressing blocks 7 are fixedly connected to the lower end of the sliding plate 5.

[0020] In this embodiment: When in use, the pallet 9 is first positioned on the upper end of the lifting platform 8, with the two forklift slots 11 of the pallet 9 facing downwards. Then, the drive mechanism drives the lead screw 13 to rotate, and drives the connecting plate 14, which is threaded to the lead screw 13, to move upwards along the lead screw 13. At the same time, the cylinder 15, the first pressure sensor 16, the lifting platform 8, and the pallet 9 rise synchronously. When the upper end face of the pallet 9 contacts the lower end face of the template 2, the first pressure sensor 16 monitors the bonding pressure in real time. The controller 23 controls the servo motor 21 to stop rotating according to the preset parameters, so that the pallet 9 and the template 2 maintain a suitable bonding force. The pallet 9 provides stable support for subsequent material filling. After the pallet 9 and the template 2 are in place, the operator fills the well-mixed brick-making raw material into the multiple forming grooves 3 of the template 2. Then, the sliding plate 5 is pushed downward by the output end of the hydraulic cylinder 4. The multiple pressing blocks 7 at the lower end of the sliding plate 5 descend synchronously with the sliding plate 5 and gradually extend into the forming grooves 3 to press the raw material. During the pressing process, the second pressure sensor 6 between the output end of the hydraulic cylinder 4 and the sliding plate 5 collects the pressing force data in real time and feeds the signal back to the controller 23. When the pressure reaches the preset value, the controller 23 controls the hydraulic cylinder 4 to stop pressing and maintain the current pressure for a set time, so that the raw material is compacted under constant pressure. After the pressing is completed, the output end of the hydraulic cylinder 4 retracts, driving the sliding plate 5 and the pressing blocks 7 to return to their original positions. When demolding is required after pressing, the drive mechanism drives the lead screw 13 to rotate in the opposite direction, causing the connecting plate 14 to move downward along the lead screw 13, which in turn drives the cylinder 15, the first pressure sensor 16, and the lifting platform 8 to descend synchronously. At this time, the left and right ends of the template 2 are fixedly connected to the connecting blocks that are fixedly connected to the frame 1. The template 2 remains stationary due to the support of the frame 1 and the connecting blocks. The support plate 9 descends with the lifting platform 8, thereby separating the bricks in the forming groove 3 from the template 2 until the bricks are located below the template 2. This can automatically realize the demolding process, replacing the traditional manual push rod operation, reducing the physical exertion of operators, and significantly improving production efficiency. After demolding, the operator inserts the forklift forks into the two forklift slots 11 at the bottom of the pallet 9 from the front side of the frame 1, starts the forklift to lift the pallet 9 together with the bricks, and transfers them to the designated storage area. By setting up a liftable carrying platform and opening forklift slots 11 on the pallet 9, the demolded bricks can be quickly transferred to the designated area by forklift along with the pallet 9, effectively reducing the cost of manual handling. As a technical optimization of this utility model, the drive mechanism includes a frame 17 fixedly connected to the lower end of the fixed plate 12. A partition 18 is fixedly connected inside the frame 17. A worm gear 19 is rotatably connected between the left end of the partition 18 and the left side of the inner wall of the frame 17. A worm wheel 20 is meshed with the outer wall of the worm gear 19. A transmission shaft is fixedly connected between the worm wheel 20 and the lead screw 13. A servo motor 21 with its output end fixedly connected to the worm gear 19 is installed at the right end of the partition 18.

[0021] In this embodiment: the output end of the servo motor 21 drives the worm 19 to rotate, the worm 19 meshes with and drives the worm wheel 20, and the worm wheel 20 drives the lead screw 13 to rotate through the transmission shaft. Since the worm 19 and the worm wheel 20 have a self-locking characteristic, the lead screw 13 can be prevented from rotating when the servo motor 21 is not started.

[0022] As a technical optimization of this utility model, a U-shaped positioning frame 10 is fixedly connected to the upper end of the lifting platform 8.

[0023] In this embodiment: the rear end of the tray 9 is made to fit against the rear end of the inner wall of the U-shaped positioning frame 10, and then the U-shaped positioning frame 10 is used to position the tray 9.

[0024] As a technical optimization of this utility model, an operation panel 22 and a controller 23 are installed on the right end of the frame 1.

[0025] In this embodiment: the operation panel 22 on the right end of the frame 1 serves as a human-machine interface, allowing operators to input working parameters and send commands. The controller 23 receives and processes these commands and controls the actions of actuators such as the servo motor 21 and the hydraulic cylinder 4 via electrical signals.

[0026] As a technical optimization of this utility model, the left and right ends of the inner wall of the frame 1 are provided with first sliding grooves, and the interior of the two first sliding grooves is slidably connected with first sliders that are fixedly connected to the sliding plate 5. The left and right ends of the inner wall of the frame 1 are provided with second sliding grooves, and the interior of the two second sliding grooves is slidably connected with second sliders that are fixedly connected to the lifting platform 8.

[0027] In this embodiment, by setting two first slide grooves, two first sliders, two second slide grooves, and two second sliders, it is ensured that the sliding plate 5 and the lifting platform 8 move up and down accurately and without deviation.

[0028] As a technical optimization of this utility model, a connecting ring is fixedly connected to the outer wall of the cylinder 15, and two anti-torsion rods that are fixedly connected to the lifting platform 8 are slidably connected through the outer wall of the connecting ring.

[0029] In this embodiment, by setting two anti-torsion bars, the first pressure sensor 16 is prevented from being subjected to torsional force when the lead screw 13 rotates.

[0030] As a technical optimization of this utility model, the frame 1 has mounting plates with multiple mounting holes fixedly connected to both the left and right ends.

[0031] In this embodiment, the device can be installed and fixed by setting two mounting plates, each with multiple mounting holes.

[0032] The working principle and usage process of this utility model are as follows: When in use, first place the pallet 9 on the upper end of the lifting platform 8, and make the two forklift slots 11 of the pallet 9 face downwards. At the same time, make the rear end of the pallet 9 fit against the rear end of the inner wall of the U-shaped positioning frame 10, and then position the pallet 9 by the U-shaped positioning frame 10. After the pallet 9 is placed, the operator sends a command to the controller 23 through the control panel 22. The controller 23 starts the servo motor 21. The output end of the servo motor 21 drives the worm gear 19 to rotate. The worm gear 19 meshes with and drives the worm wheel 20. The worm wheel 20 drives the lead screw 13 to rotate through the transmission shaft. It also drives the connecting plate 14, which is threaded to the lead screw 13, to move upward along the lead screw 13. At the same time, it drives the cylinder 15, the first pressure sensor 16, the lifting platform 8, and the pallet 9 to rise synchronously. When the upper surface of the pallet 9 contacts the lower surface of the template 2, the first pressure sensor 16 monitors the bonding pressure in real time. The controller 23 controls the servo motor 21 to stop rotating according to the preset parameters, so that the pallet 9 and the template 2 maintain a suitable bonding force. The pallet 9 provides stable support for subsequent material filling. After the pallet 9 and the template 2 are in place, the operator fills the well-mixed brick-making raw material into the multiple forming grooves 3 of the template 2. Then, the operator sends a command to the controller 23 through the control panel 22. The controller 23 controls the hydraulic cylinder 4 to start. The output end of the hydraulic cylinder 4 pushes the sliding plate 5 downward. The multiple pressing blocks 7 at the lower end of the sliding plate 5 descend synchronously with the sliding plate 5 and gradually extend into the forming grooves 3 to press the raw material. During the pressing process, the second pressure sensor 6 between the output end of the hydraulic cylinder 4 and the sliding plate 5 collects the pressing force data in real time and feeds the signal back to the controller 23. When the pressure reaches the preset value, the controller 23 controls the hydraulic cylinder 4 to stop pressing and maintain the current pressure for a set time, so that the raw material is compacted under constant pressure. After pressing is completed, the output end of the hydraulic cylinder 4 retracts, driving the sliding plate 5 and the pressing blocks 7 to return to their original position. When demolding is required after pressing, the control panel 22 sends a command to the controller 23, and the servo motor 21 rotates in the opposite direction. Through the rotation of the worm gear 19, worm wheel 20, lead screw 13 and transmission shaft, the connecting plate 14 moves downward along the lead screw 13, driving the cylinder 15, the first pressure sensor 16 and the lifting platform 8 to descend synchronously. At this time, the left and right ends of the template 2 are fixedly connected to the connecting blocks that are fixedly connected to the frame 1. The template 2 remains stationary due to the support of the frame 1 and the connecting blocks. The support plate 9 descends with the lifting platform 8, thereby separating the bricks in the forming groove 3 from the template 2 until the bricks are located below the template 2. This can automatically realize the demolding process, replacing the traditional manual push rod operation, reducing the physical exertion of operators, and significantly improving production efficiency. After demolding, the operator inserts the forklift forks into the two forklift slots 11 at the bottom of the pallet 9 from the front side of the frame 1, starts the forklift to lift the pallet 9 together with the bricks, and transfers them to the designated storage area. By setting up a liftable carrying platform and opening forklift slots 11 on the pallet 9, the demolded bricks can be quickly transferred to the designated area by forklift along with the pallet 9, effectively reducing the cost of manual handling.
