Description

Technical Field

[0001] This invention relates to the field of brick making machines, and more specifically, to a molding device for producing fly ash-based lightweight thermal insulation blocks. Background Technology

[0002] Fly ash-based lightweight insulating blocks, as a new type of building material that utilizes waste, is environmentally friendly, and energy-saving, are widely used in building wall filling and insulation projects. In its production process, demolding after molding is a crucial step, as the demolding effect directly affects the product's yield, appearance quality, and production efficiency.

[0003] One existing molding device uses vibration demolding, where a vibrator is installed on the mold to separate the block from the inner wall of the mold through high-frequency vibration. While this method has some effect, it also has significant drawbacks. Strong vibrations can easily cause edge damage or internal micro-cracks in blocks that have not yet fully developed their strength, especially for lightweight, porous products, making it difficult to guarantee a high yield. Furthermore, the vibration process generates significant noise pollution, consumes a lot of energy, and for highly viscous fly ash materials, demolding is not thorough.

[0004] Secondly, an ejector-type demolding method is used, which involves installing hydraulically or pneumatically driven ejector rods or plates below the mold. During demolding, the ejector mechanism pushes the block upwards from the molding cavity. Although this method is more direct than vibration demolding, it also has disadvantages. The ejector mechanism requires an additional power system and a complex control system, making the overall structure of the equipment complex, increasing manufacturing costs, and making maintenance inconvenient.

[0005] In view of this, we propose a molding device for producing fly ash-based lightweight thermal insulation blocks. Summary of the Invention

[0006] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a molding device for producing fly ash-based lightweight thermal insulation blocks. The device uses a receiving block to smoothly and evenly push the blocks upwards under the action of a protrusion. The force is vertically upward, avoiding damage to the internal structure of the blocks from vibration, protecting the edges and integrity of the blocks, and improving the yield rate. Utilizing the flipping action itself as a power source, the rotational force of the flipping is directly converted into the linear force of the ejection. The flipping component drives both actions, eliminating the need for a dedicated ejection power system, thus simplifying the equipment structure and reducing manufacturing costs and maintenance difficulty.

[0007] This invention provides the following technical solution: a molding device for producing fly ash-based lightweight thermal insulation blocks, comprising an installation frame, a positioning column fixedly installed inside the installation frame, a reserved groove opened on the outer wall of the positioning column, a rotating ring rotatably connected inside the reserved groove, a fixed sleeve fixedly connected to the outer wall of the rotating ring, a molding frame fixedly connected to the outer wall of the fixed sleeve, an arc-shaped limiting plate fixedly connected to the inner wall of the installation frame, the fixed sleeve and the limiting plate forming an movable gap, and flipping components installed on both sides of the installation frame;

The inner wall of the fixing sleeve is slidably connected to a receiving block. The top of the receiving block is provided with multiple ends, and the multiple ends are slidably connected to the inner wall of the corresponding forming groove. The bottom of the receiving block is provided with an arc-shaped sliding groove.

[0009] The flipping component is used to drive the fixed sleeve to rotate, so that the fixed sleeve drives the forming frame to rotate downward along the movable gap. At the same time, the fixed sleeve drives the receiving block to rotate, so that the receiving block slides along the outer wall of the positioning column through the sliding groove at the bottom. The protrusion on the positioning column presses the receiving block downward, and the end of the receiving block slides along the forming groove to press and demold the formed brick.

[0010] Preferably, a hydraulic cylinder is fixedly connected to the top of the mounting frame, the output end of the hydraulic cylinder passes through the mounting frame and is slidably connected to it, and a pressure plate is fixedly connected to the output end of the hydraulic cylinder. The bottom of the pressure plate is provided with multiple protrusions. The hydraulic cylinder pushes the pressure plate downward, causing the multiple protrusions to slide towards the inner wall of the forming groove, thereby extruding and forming the fly ash.

[0011] Preferably, the top of the pressure plate is fixedly connected to two guide rods, the top of which passes through the mounting bracket and is slidably connected to it.

[0012] Preferably, a support plate is fixedly connected to the inner wall of the mounting frame. When the forming frame is rotated to a vertical state, the opening of the forming groove on it faces upward, the end of the support plate abuts against the side wall of the forming frame, and the top surface of the support plate is flush with the top surface of the forming frame.

[0013] Preferably, a metering frame is slidably connected to the top of the pressure plate, and sliders are fixedly connected to both sides of the metering frame. Two sliding rods are fixedly connected to the inner walls of both sides of the mounting frame, and the ends of the sliding rods pass through the sliders and are slidably connected to them.

[0014] Preferably, a first cylinder is fixedly connected to the top of the pressure plate, and the output end of the first cylinder is fixedly connected to the metering frame.

[0015] Preferably, a conveyor is installed on the inner wall of the mounting frame, and the conveyor is used to transport the molded bricks after demolding.

[0016] Preferably, the flipping assembly includes a mounting plate, which is fixedly connected to the outer wall of the mounting frame. An output shaft is rotatably connected to the inner wall of the mounting plate. The end of the output shaft is fixedly connected to a positioning post. A first drive gear is fixedly connected to the outer wall of the output shaft. A rotating arm is fixedly connected to the outer wall of the output shaft. A connecting shaft is rotatably connected to the end of the rotating arm. The end of the connecting shaft is fixedly connected to a fixing sleeve.

[0017] Preferably, a drive shaft is rotatably connected to the outer wall of the mounting plate, and a second drive gear is fixedly connected to the outer wall of both the drive shaft and the output shaft, with the two second drive gears meshing with each other.

[0018] Preferably, the flipping assembly further includes a second cylinder. A base is fixedly connected to the outer wall of the mounting bracket. The base is fixedly connected to the second cylinder. A connecting plate is fixedly connected to the output end of the second cylinder. Two connecting rods are fixedly connected to the outer wall of the connecting plate. The ends of the connecting rods pass through the mounting plate and are slidably connected to it. A drive gear plate is fixedly connected to the ends of the connecting rods respectively. A sliding groove is provided on the inner wall of the mounting plate. A movable hole is provided on the inner wall of the sliding groove. The sliding groove communicates with the movable hole. The drive gear plate is slidably connected to the sliding groove and the movable hole respectively. The upper drive gear plate meshes with the first drive gear, and the lower drive gear plate meshes with the second drive gear.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] In this invention, the receiving block smoothly and evenly pushes the block upwards under the action of the protrusion. The force is vertically upward, avoiding damage to the internal structure of the block from vibration, protecting the block's edges and integrity, and improving the yield rate. The demolding force in this invention does not come from a separate hydraulic or pneumatic device, but utilizes the flipping action itself as a power source. Through a cam mechanism formed by the positioning column protrusion and the receiving block's sliding groove, the rotational force of the flipping is directly converted into the linear force of the ejection. The flipping component drives two actions, eliminating the need for a dedicated ejection power system, simplifying the equipment structure, and reducing manufacturing costs and maintenance difficulty. This invention designs a composite demolding action of flipping and ejection. Flipping causes the block to naturally detach under gravity, while ejection actively overcomes residual adhesion. The two work together to create a push-pull effect, resulting in more thorough and smooth demolding, especially suitable for complex-shaped blocks, avoiding mold jamming. Because the demolding action is integrated into the flipping process, no separate demolding step is needed, shortening the production cycle, making the action smooth and continuous, highly automated, and improving production efficiency.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] like Figures 1-6 As shown, a molding device for producing fly ash-based lightweight thermal insulation blocks includes an installation frame. A positioning column 26 is fixedly installed inside the installation frame. A reserved groove 32 is opened on the outer wall of the positioning column 26. A rotating ring 31 is rotatably connected inside the reserved groove 32. A fixing sleeve 25 is fixedly connected to the outer wall of the rotating ring 31. A molding frame 28 is fixedly connected to the outer wall of the fixing sleeve 25. An arc-shaped limiting plate 33 is fixedly connected to the inner wall of the installation frame. The fixing sleeve 25 and the limiting plate 33 form an movable gap. A flipping component is installed on both sides of the installation frame.

[0032] The outer wall of the positioning post 26 protrudes downward to form an arc-shaped protrusion. The inner wall of the molding frame 28 has multiple molding grooves 29. The inner wall of the fixing sleeve 25 is slidably connected to a receiving block 27. The top of the receiving block 27 has multiple ends, which are slidably connected to the inner wall of the corresponding molding groove 29. The bottom of the receiving block 27 has an arc-shaped sliding groove 30. The flipping component is used to drive the fixing sleeve 25 to rotate, so that the fixing sleeve 25 drives the molding frame 28 to rotate downward along the movable gap. At the same time, the fixing sleeve 25 drives the receiving block 27 to rotate, so that the receiving block 27 slides along the outer wall of the positioning post 26 through the sliding groove 30 at the bottom. The protrusion on the positioning post 26 presses the receiving block 27 downward. The end on the receiving block 27 slides along the molding groove 29 to press and demold the molded brick.

[0033] By setting up the flipping component, the protruding part of the positioning column 26, and the receiving block 27, demolding is achieved by mechanical extrusion when the forming frame 28 rotates, which replaces the traditional vibration demolding. This avoids damage to the edges and corners of the blocks and internal micro-cracks caused by vibration, and is especially suitable for lightweight porous blocks, thus improving the yield rate. At the same time, there is no need for a complex ejection mechanism power and control system, which simplifies the equipment structure and reduces manufacturing costs and maintenance difficulty.

[0034] like Figure 1 and Figure 2 As shown, a hydraulic cylinder 3 is fixedly connected to the top of the mounting frame. The output end of the hydraulic cylinder 3 passes through the mounting frame and is slidably connected to it. A pressure plate 5 is fixedly connected to the output end of the hydraulic cylinder 3. The bottom of the pressure plate 5 is provided with multiple protrusions. The hydraulic cylinder 3 pushes the pressure plate 5 to move downward, so that the multiple protrusions slide towards the inner wall of the forming groove 29 to extrude and form the fly ash.

[0035] Two guide rods 4 are fixedly connected to the top of the pressure plate 5. The top of the guide rods 4 passes through the mounting bracket and is slidably connected to it.

[0036] Hydraulic cylinder 3 provides extrusion force to ensure that fly ash raw materials are fully compacted; the protrusion at the bottom of pressure plate 5 is adapted to the forming groove 29 to ensure that the block forming shape is consistent.

[0037] The guide rod 4 restricts the sliding trajectory of the pressure plate 5, preventing the pressure plate 5 from tilting due to uneven force, ensuring that the bottom protrusion of the pressure plate 5 extends evenly into each forming groove 29, so that the extrusion force of the raw material in all forming grooves 29 is consistent, improving the density uniformity of the block, and avoiding insufficient strength due to density differences.

[0038] The mounting frame has a fixed support plate 8 on its inner wall. When the forming frame 28 is rotated to a vertical position, the opening of the forming groove 29 on it faces upward, the end of the support plate 8 abuts against the side wall of the forming frame 28, and the top surface of the support plate 8 is flush with the top surface of the forming frame 28.

[0039] like Figure 1 and Figure 2 As shown, the pallet 8 abuts against and is flush with the vertical forming frame 28, providing support for the feeding of the quantitative frame 9, preventing the raw material from spilling when it is poured into the forming trough 29, and reducing material waste; at the same time, the pallet 8 can prevent the forming frame 28 from shifting under the action of the weight of the raw material.

[0040] A metering frame 9 is slidably connected to the top of the pressure plate 5. Slider 7 is fixedly connected to both sides of the metering frame 9. Two slide rods 6 are fixedly connected to the inner walls of both sides of the mounting frame. The ends of the slide rods 6 pass through the sliders 7 and are slidably connected to them.

[0041] The quantitative frame 9 can pre-store a fixed amount of fly ash raw material, ensuring that the amount of raw material poured into the molding tank 29 is consistent each time, avoiding the problem of too much or too little material when manually feeding, ensuring uniform block thickness and weight, and improving product consistency.

[0042] A first cylinder 10 is fixedly connected to the top of the pressure plate 5. The output end of the first cylinder 10 is fixedly connected to the metering frame 9. A conveyor 2 is installed on the inner wall of the mounting frame. The conveyor 2 is used to transport the molded bricks after demolding.

[0043] like Figures 3-7As shown, the flipping assembly includes a mounting plate 15, which is fixedly connected to the outer wall of the mounting frame. An output shaft 20 is rotatably connected to the inner wall of the mounting plate 15. The end of the output shaft 20 is fixedly connected to a positioning post 26. A first drive gear 21 is fixedly connected to the outer wall of the output shaft 20. A rotating arm 23 is fixedly connected to the outer wall of the output shaft 20. A connecting shaft 24 is rotatably connected to the end of the rotating arm 23. The end of the connecting shaft 24 is fixedly connected to a fixing sleeve 25. A drive shaft 19 is rotatably connected to the outer wall of the mounting plate 15. A second drive gear 22 is fixedly connected to the outer walls of both the drive shaft 19 and the output shaft 20. The two second drive gears 22 mesh with each other. The flipping assembly also includes a second cylinder 12. A base 11 is fixedly connected to the outer wall of the mounting bracket. The base 11 is fixedly connected to the second cylinder 12. A connecting plate 13 is fixedly connected to the output end of the second cylinder 12. Two connecting rods 14 are fixedly connected to the outer wall of the connecting plate 13. The ends of the connecting rods 14 pass through the mounting plate 15 and are slidably connected to it. Drive gear plates 18 are fixedly connected to the ends of the connecting rods 14 respectively. A sliding groove 16 is opened in the inner wall of the mounting plate 15. A movable hole 17 is opened in the inner wall of the sliding groove 16. The sliding groove 16 communicates with the movable hole 17. The drive gear plates 18 are slidably connected to the sliding groove 16 and the movable hole 17 respectively. The upper drive gear plate 18 meshes with the first drive gear 21, and the lower drive gear plate 18 meshes with the second drive gear 22.

[0044] The fixed connection between the output shaft 20 and the rotating arm 23 ensures that the force is balanced when the fixed sleeve 25 drives the molding frame 28 to rotate, and avoids the demolding misalignment caused by the force offset on one side of the molding frame 28; the rotating connection between the connecting shaft 24 and the fixed sleeve 25 can buffer the rigid impact during rotation and protect the molding frame 28 and the receiving block 27.

[0045] Mounting plate 15 integrates output shaft 20 and rotating arm 23, making the flipping assembly structure compact, easy to assemble with mounting frame, and reducing the space occupied by the equipment.

[0046] The two second drive gears 22 mesh to ensure that the drive shaft 19 and the output shaft 20 rotate synchronously, thereby making the forces on both sides of the fixed sleeve 25 consistent, preventing the molding frame 28 from tilting when rotating, ensuring accurate contact between the receiving block 27 and the protrusion of the positioning post 26 during demolding, and improving demolding stability.

[0047] The second cylinder 12 meshes with the gear through the drive gear plate 18, which can control the rotation angle of the output shaft 20, ensuring that the receiving block 27 is in contact with the protrusion of the positioning post 26. The slide groove 16 and the movable hole 17 provide sliding guidance for the drive gear plate 18, avoiding misalignment of the gear plate meshing and improving the reliability of the transmission.

[0048] In this design, a receiving block 27 is provided with multiple ends. These ends rise synchronously, which can ensure that a uniform jacking force is applied to multiple blocks or even different parts of a block, further reducing the risk of breakage.

[0049] Traditional ejection mechanisms need to be placed directly below the mold, occupying a large amount of vertical space and conflicting with the mold base design. The integrated design of the fixed sleeve 25, positioning post 26, and receiving block 27 in this solution results in a compact structure, high space utilization, and easy integration with other automation modules.

[0050] It abandons the high-energy-consuming and high-noise vibration motor and adopts a mechanical linkage method. The main energy consumption is in the drive cylinder and hydraulic cylinder 3. The overall operation is more energy-efficient and quieter, which can improve the working environment.

[0051] Compared to complex hydraulic ejection systems or easily damaged vibratory motors, purely mechanical linkage structures have fewer failure points, less wear on moving parts, longer service life, and higher reliability.

[0052] In traditional designs, driving a rotating mechanism typically involves a single motor or a cylinder paired with a rack. This invention utilizes a linear power source to achieve two-point meshing transmission. The upper gear plate drives the first drive gear 21, and the lower gear plate drives the second drive gear 22. The two gears mesh with each other, resulting in a stronger torque output capability and smoother operation of the transmission system. This overcomes the backlash error and mechanism jamming problems that can occur with single-point meshing, making the entire flipping process smoother and more powerful.

[0053] Working principle: The external automatic feeder pours the preset amount of fly ash raw material into the forming groove 29 of the forming frame 28. The first cylinder 10 is started, pushing the quantitative frame 9 to slide along the slide bar 6 and move the quantitative frame 9 above the forming frame 28. The fly ash in the quantitative frame 9 enters the forming groove 29 respectively. Then the first cylinder 10 drives the quantitative frame 9 to reset. At this time, the forming frame 28 is in a vertical state.

[0054] Start the hydraulic cylinder 3 to push the pressure plate 5 to slide downward along the guide rod 4. The protrusion at the bottom of the pressure plate 5 extends into the forming groove 29 to apply pressure to the fly ash raw material and squeeze it into a block of the preset shape. The guide rod 4 ensures that the pressure plate 5 is subjected to uniform force and avoids the difference in block density caused by uneven extrusion of raw materials in the forming groove 29.

[0055] The second cylinder 12 of the flipping assembly is activated, which pushes the connecting plate 13 and the connecting rod 14 to move, causing the drive tooth plate 18 to slide along the slide groove 16 and the movable hole 17. The upper drive tooth plate 18 meshes with the first drive gear 21, which drives the output shaft 20 and the rotating arm 23 to rotate. The lower drive tooth plate 18 meshes with the second drive gear 22, which drives the output shaft 20 to rotate synchronously through the drive shaft 19. Finally, the fixed sleeve 25 drives the forming frame 28 to rotate downward along the movable gap of the limiting plate 33.

[0056] During rotation, the fixed sleeve 25 drives the receiving block 27 to rotate synchronously, and the sliding groove 30 at the bottom of the receiving block 27 slides along the outer wall of the positioning post 26. When the sliding groove 30 contacts the arc-shaped protrusion of the positioning post 26, the protrusion presses the receiving block 27 downward, causing the top end of the receiving block 27 to slide upward along the inner wall of the forming groove 29, pushing the formed block out of the forming groove 29, thus completing the vibration-free demolding.

[0057] After demolding, the blocks fall onto conveyor 2 and are transported by conveyor 2 to the subsequent curing station, thus connecting molding, demolding and conveying.

[0058] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
