Abstract
Description
Technical Field
[0001] This invention relates to the field of aerated concrete production technology, and in particular to an aerated concrete block mold frame. Background Technology
[0002] Autoclaved aerated concrete (AAC) blocks are a high-performance, energy-saving, lightweight building material widely used due to their thermal insulation, fireproofing, and sound insulation properties. The production of AAC blocks is a process that requires extremely high stability of the equipment. The casting mold is the core carrier that holds the slurry, completes the gas generation, initial setting, and transportation. Its performance directly determines the quality of the final product and the production cost. The inside of the casting mold is the slurry in the early stage of intense chemical reaction and structural formation, and it is extremely sensitive to mechanical vibration and lateral shaking.
[0003] Currently, the movement of the mold box on the track relies entirely on the natural coordination between its wheels and the track. When the mold box starts, stops, or passes through the track joint, the lateral sway caused by inertia cannot be effectively restrained, resulting in shear force on the internal blank. In addition, vibrations from the track foundation or adjacent equipment are directly transmitted to the blank through the wheels. These vibrations and swaying severely interfere with the uniform formation and stable existence of air bubbles, causing small air bubbles to merge into harmful large air bubbles, and even destroying the formed gel structure, forming micro-cracks or stress concentration points inside the blank. This directly leads to large dispersion in the strength of the finished blocks and a low pass rate. Secondly, the mold box consists of two parts: the mold frame and the base plate. The two are locked together by bolts or mechanical pressure bars. During the movement and transportation of slurry, the weakest parts of the locking force are prone to micro-tension and slurry leakage, which also reduces the quality of aerated concrete blocks. Summary of the Invention
[0004] To overcome the shortcomings of the prior art, the present invention provides an aerated concrete block mold frame.
[0005] To solve the above technical problems, the present invention provides the following technical solution: an aerated concrete block mold frame, including a casting mold frame and a fixed base plate, wherein an expansion limiting component is provided at the bottom of the casting mold frame, the expansion limiting component is used to limit the movement of the moving casting mold frame, and the limiting side plate provided in the expansion limiting component provides anti-sway support for the casting mold frame.
[0006] The expansion limiting component includes a first fixing plate, a fixing seat and a bidirectional motor. The first fixing plate is fixedly installed at the center of both ends of the bottom of the casting mold frame, and the fixing seat is fixedly installed on the first fixing plate.
[0007] The limiting side plate is also provided with a limiting sliding component, in which the limiting roller is installed to move and abut against the conveying track;
[0008] A fixed base plate is movably installed on the side of the casting mold frame, and an interlocking fixing component is installed on the top of the casting mold frame. The arc-shaped interlocking block in the interlocking fixing component presses and interlocks with the top two ends of the fixed base plate.
[0009] The interlocking fixing assembly includes a support plate fixedly installed at the top of the casting mold frame. The fixed base plate is also provided with a sealing overlapping assembly that cooperates with the casting mold frame to seal. The U-shaped sealing strip in the sealing overlapping assembly reinforces and seals the casting mold frame and the fixed base plate.
[0010] As a preferred embodiment of the present invention, a bearing base is welded and fixedly installed around the bottom perimeter of the casting mold frame. A conveying roller is fixedly installed on the bearing base via a rotating shaft, and the conveying roller moves in a limited and fitted manner with the conveying track. The expansion limiting component also includes a screw that is movable on the fixed seat. The fixed seat is threadedly connected to the screw at the end away from the first fixed plate. The bidirectional motor is fixedly installed at the bottom center of the casting mold frame by bolts. The screw is fixedly installed on the output ends of both ends of the bidirectional motor. A second fixed plate is fixedly installed at the bottom of the casting mold frame, and the screw moves through the second fixed plate.
[0011] The fixed base is a cylindrical structure. Both ends of the fixed base are movably connected to the hinge rod through hinges. The limiting side plate is movably connected to the hinge rod through hinges. A moving block is threaded through the screw. Push rods are movably connected between the two ends of the moving block and the limiting side plate through hinges.
[0012] As a preferred embodiment of the present invention, the limiting sliding assembly further includes a telescopic spring. A plurality of arc-shaped limiting seats are evenly installed on the side of the limiting side plate away from the fixed seat. The arc-shaped limiting seats have arc-shaped limiting holes on the side away from the fixed seat. The inner bottom of the arc-shaped limiting holes is fixedly installed with a telescopic spring by bolts.
[0013] The telescopic spring has a limit roller fixedly installed at the end away from the fixed base by bolts, and the bottom of the limit roller moves in the arc-shaped limit hole.
[0014] As a preferred embodiment of the present invention, the interlocking fixing assembly further includes a hydraulic telescopic rod. A support cylinder is fixedly installed on the side of the support plate away from the casting mold frame by bolts. A hydraulic telescopic rod is fixedly installed on the inner bottom of the support cylinder by bolts. A connecting plate is welded and fixed at the center of the end of the support plate near the fixed base plate. A support shaft is movably connected to the top of the connecting plate. A first connecting plate is movably connected to both ends of the support shaft. An arc-shaped interlocking block is movably connected to the top of the first connecting plate through the shaft.
[0015] A push-pull block is fixedly installed at the top output end of the hydraulic telescopic rod. A second connecting plate is movably connected to the end of the push-pull block near the connecting plate via a rotating shaft. A third connecting plate is movably connected to the end of the push-pull block away from the connecting plate via a rotating shaft. The second connecting plate is movably connected to the middle position of the first connecting plate via a rotating shaft. The third connecting plate is movably connected to the arc-shaped interlocking block via a rotating shaft. Wedge-shaped bottom blocks are fixedly installed at both ends of the top of the fixed base plate via bolts. The wedge-shaped bottom blocks cooperate with the arc-shaped interlocking blocks to press the fixed base plate tightly against the casting mold frame.
[0016] As a preferred embodiment of the present invention, the sealing and overlapping assembly includes a hydraulic telescopic pump, a square mounting block is fixedly installed on the side of the fixed base plate away from the casting mold frame by bolts, a hydraulic telescopic pump is fixedly installed on the bottom of the casting mold frame near the fixed base plate by bolts, a triangular base block is fixedly installed on the top of the output end of the hydraulic telescopic pump, and the triangular base block matches the square mounting block, with the square mounting block movable at the top of the triangular base block.
[0017] The casting mold frame has a U-shaped sealing groove on one side of the fixed base plate. A U-shaped sealing strip is welded and fixed to the fixed base plate, and the U-shaped sealing strip matches the U-shaped sealing groove. The U-shaped sealing strip moves within the U-shaped sealing groove.
[0018] Compared with the prior art, the beneficial effects that this invention can achieve are:
[0019] 1. In this invention, the expansion limiting component set at the bottom of the mold frame can actively extend during the movement of the mold box, and the limiting roller supported by the buffer spring tightly abuts against both sides of the conveying track, forming an effective dynamic lateral constraint. This greatly suppresses the lateral swaying and vibration generated by the mold box during start-up, stopping and movement, providing an ultra-stable moving environment for the internal slurry. It effectively prevents bubble merging, deformation or structural damage caused by external disturbance, thereby significantly reducing the generation of defects such as internal cracks and large bubbles in the finished block, and improving the product strength grade and pass rate.
[0020] 2. In this invention, a bidirectional motor drives a symmetrically arranged screw mechanism, which precisely displaces the moving block along the axial direction. The power is then transmitted via a push rod to the hinged limiting side plates on both sides, achieving synchronous and stable radial expansion. This dynamically applies lateral constraints during mold box movement, effectively suppressing lateral swaying and low-frequency vibrations caused by uneven tracks and start-stop impacts. It provides a near-ideal quasi-static moving environment for the gas expansion and initial solidification of the slurry inside the mold box. The symmetrically expanding limiting side plates, in conjunction with the bottom conveyor rollers that bear the main load, form a comprehensive system that addresses both internal and external needs. The collaborative stabilization system uses conveyor rollers to provide vertical support and smooth rolling, while limiting side plates are responsible for horizontal positioning and anti-swaying. The two complement each other, significantly enhancing the overall stability and attitude controllability of the mold box under complex working conditions. This fundamentally reduces the adverse effects of external mechanical disturbances on the microstructure of the blank, effectively preventing abnormal merging, dissipation, or morphological distortion of air bubbles before curing. At the same time, it reduces the risk of microcracks caused by vibration stress concentration. The final block product has a more uniform and complete internal pore structure, and the overall mechanical properties and yield are significantly improved.
[0021] 3. In this invention, the telescopic spring and the limiting roller in the limiting sliding assembly form a highly efficient buffer structure. Under the preload of the telescopic spring, the limiting roller presses tightly against the side wall of the conveying track, which not only provides precise guidance but also absorbs and dissipates the impact and vibration energy from the track. This not only protects the structure of the mold box body and reduces deformation and wear under long-term use, but also reduces impact damage to the conveying track and extends the service life of the casting mold frame.
[0022] 4. In this invention, the push-pull block is driven by the hydraulic telescopic rod through the interlocking fixing component, and the vertical thrust of the hydraulic cylinder is converted into a strong downward pressing force of the arc-shaped interlocking block on the wedge-shaped abutment by the multi-link force amplification mechanism composed of the second connecting plate, the first connecting plate and the third connecting plate. This lever and linkage composite mechanism can generate a pressing force far exceeding that of conventional bolt locking, ensuring that the fixed base plate and the casting mold frame are firmly mechanically locked at the top during the casting and gas generation process, effectively preventing the joint from slightly opening due to increased internal pressure.
[0023] 5. In this invention, a reliable double sealing guarantee is formed by the coordinated work of the sealing overlapping component and the interlocking fixing component. The hydraulic telescopic pump generates a force that presses the fixed base plate against the casting mold frame through the cooperation of the triangular base block and the square mounting block, so that the U-shaped sealing strip is fully compressed and embedded into the U-shaped sealing groove, forming the first tight static seal. Subsequently, the top pressing force applied by the interlocking fixing component further enhances the sealing effect. The synergistic mechanism of first sealing tightly and then pressing and locking fundamentally eliminates the possibility of grout leakage from the joint. Attached Figure Description

[0035] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.
[0036] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, an aerated concrete block mold frame includes a casting mold frame 10 and a fixed base plate 11. An expansion limiting component is provided at the bottom of the casting mold frame 10. The expansion limiting component is used to limit the movement of the casting mold frame 10. The limiting side plate 30 provided in the expansion limiting component provides anti-sway support for the casting mold frame 10. The expansion limiting component includes a first fixing plate 20, a fixing seat 21 and a bidirectional motor 22. The first fixing plate 20 is fixedly installed at the center of both ends of the bottom of the casting mold frame 10, and the fixing seat 21 is fixedly installed on the first fixing plate 20.
[0037] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 Bearing bases 12 are welded and fixedly installed around the bottom of the casting mold frame 10. Conveying rollers 13 are fixedly installed on the bearing bases 12 via rotating shafts, and the conveying rollers 13 move in a limited and fitted manner with the conveying track 14. The stable conveying and transfer of the casting mold box is achieved through the cooperation of the conveying rollers 13 and the conveying track 14. The expansion limiting component also includes screws 23 movable on the fixed base 21. Screws 23 are threadedly connected to the end of the fixed base 21 away from the first fixed plate 20. A bidirectional motor 22 is fixedly installed at the bottom center of the casting mold frame 10 by bolts, and screws 23 are fixedly installed on the bidirectional motor. At the output ends of the two ends of the casting mold frame 10, a second fixed plate 24 is fixedly installed at the bottom, and the screw 23 is movably connected through the second fixed plate 24, so that the screw 23 is stably moved on the fixed seat 21. The fixed seat 21 is a cylindrical structure, and both ends of the fixed seat 21 are movably connected to the hinge rod 25 through hinges. The limiting side plate 30 is movably connected to the hinge rod 25 through hinges. A moving block 26 is threaded through the screw 23. The two ends of the moving block 26 and the limiting side plate 30 are movably connected to the push rod 27 through hinges, and the push rod 27 and the hinge rod 25 form a triangular structure.
[0038] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 During the transportation process, the fully loaded mold box is moved on the conveyor track 14 by the conveyor rollers 13. The workshop personnel start the bidirectional motor 22 at the bottom of the mold frame. The motor drives the two screws 23 to rotate, causing the moving blocks 26 on the screws 23 to move to both sides. The moving blocks 26 transmit the force to the limiting side plate 30 hinged to the fixed seat 21 through the push rod 27. The limiting side plate 30 unfolds outward with the cooperation of the push rod 27 and the hinge rod 25. The limiting rollers 33 installed on the limiting side plate 30, under the preload of the telescopic spring 32, firmly abut against the inner walls of both sides of the conveyor track 14. In this way, the entire mold frame is restricted to the center of the track during the movement, effectively suppressing lateral swaying and vibration, protecting the unformed blank structure inside, and avoiding bubbles and internal cracks caused by swaying.
[0039] See Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The limiting side plate 30 is also provided with a limiting sliding assembly. The limiting roller 33 in the limiting sliding assembly moves against the conveying track 14. The limiting sliding assembly also includes a telescopic spring 32. Several arc-shaped limiting seats 34 are evenly installed on the side of the limiting side plate 30 away from the fixed seat 21. The arc-shaped limiting seat 34 has an arc-shaped limiting hole 31 on the side away from the fixed seat 21. The inner bottom of the arc-shaped limiting hole 31 is fixedly installed with a telescopic spring 32 by bolts. The telescopic spring 32 increases the toughness between the limiting roller 33 and the conveying track 14. The end of the telescopic spring 32 away from the fixed seat 21 is fixedly installed with a limiting roller 33 by bolts, and the bottom of the limiting roller 33 moves in the arc-shaped limiting hole 31.
[0040] See Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 Workshop personnel start the bidirectional motor 22 at the bottom of the mold frame. The motor drives the two screws 23 to rotate, causing the moving blocks 26 on the screws 23 to move to both sides. The moving blocks 26 transmit force to the limiting side plates 30 hinged to the fixed base 21 through the push rod 27. The limiting side plates 30 unfold outward with the cooperation of the push rod 27 and the hinge rod 25. The limiting rollers 33 installed on the limiting side plates 30, under the preload of the telescopic spring 32, steadily abut against the inner walls of both sides of the conveying track 14.
[0041] See Figure 1 , Figure 2 , Figure 3 , Figure 8 , Figure 9 and Figure 10 A fixed base plate 11 is movably provided on the side of the casting mold frame 10. A snapping fixing assembly is provided on the top of the casting mold frame 10. The arc-shaped snapping block 46 provided in the snapping fixing assembly presses and snaps against the top two ends of the fixed base plate 11. The snapping fixing assembly includes a support plate 40 fixedly installed at the top of the casting mold frame 10 and a hydraulic telescopic rod 42. A support cylinder 41 is fixedly installed on the side of the support plate 40 away from the casting mold frame 10 by bolts. The hydraulic telescopic rod 42 is fixedly installed on the inner bottom of the support cylinder 41 by bolts. A connecting plate 43 is welded and fixed at the center of the end of the support plate 40 near the fixed base plate 11. A support shaft 44 is movably connected to the top of the connecting plate 43. A first connecting plate 45 is movably connected to both ends of the support shaft 44. The arc-shaped snapping block 46 is movably connected to the top of the first connecting plate 45 through the shaft.
[0042] See Figure 1 , Figure 2 , Figure 3 , Figure 8 , Figure 9 and Figure 10 A push-pull block 47 is fixedly installed at the top output end of the hydraulic telescopic rod 42. The push-pull block 47 is movably connected to a second connecting plate 48 via a pivot at one end near the connecting plate 43. The push-pull block 47 is movably connected to a third connecting plate 49 via a pivot at the other end away from the connecting plate 43. The second connecting plate 48 is movably connected to the middle position of the first connecting plate 45 via a pivot. The third connecting plate 49 is movably connected to the arc-shaped interlocking block 46 via a pivot. Wedge-shaped bottom blocks 15 are fixedly installed at both ends of the top of the fixed base plate 11 by bolts. The wedge-shaped bottom blocks 15 cooperate with the arc-shaped interlocking block 46 to press the fixed base plate 11 tightly against the casting mold frame 10.
[0043] See Figure 1 , Figure 2 , Figure 3 , Figure 8 , Figure 9 and Figure 10 The hydraulic telescopic rod 42 on the support plate 40 extends upward, pushing the push-pull block 47 upward. The movement of the push-pull block 47 is transmitted to the first connecting plate 45 through the second connecting plate 48, making it rotate around the support shaft 44 on the connecting plate 43 like a lever. At the same time, the push-pull block 47 also pulls the lower end of the arc-shaped biting block 46 directly through the third connecting plate 49. The combination of these two actions makes the arc-shaped biting block 46 like a claw, tightly pressing it onto the wedge-shaped bottom block 15 on the top of the fixed base plate 11, completing the mechanical reinforcement and locking between the fixed base plate 11 and the top of the casting mold frame 10.
[0044] See Figure 1 , Figure 2, Figure 3 , Figure 4 and Figure 5 The fixed base plate 11 is also equipped with a sealing overlap assembly that cooperates with and seals against the casting mold frame 10. A U-shaped sealing strip 54 in the sealing overlap assembly reinforces and seals the casting mold frame 10 and the fixed base plate 11. The sealing overlap assembly includes a hydraulic telescopic pump 50. A square mounting block 51 is bolted to the side of the fixed base plate 11 away from the casting mold frame 10. A hydraulic telescopic pump 50 is bolted to the bottom of the casting mold frame 10 on the side closest to the fixed base plate 11. A triangular base block 52 is fixedly installed on the top of the output end of the 0, and the triangular base block 52 matches the square mounting block 51. The square mounting block 51 moves at the top of the triangular base block 52. When the hydraulic telescopic pump 50 retracts, it attaches the fixed base plate 11 to the side of the casting mold frame 10 to achieve a seal on the casting mold frame 10. When the hydraulic telescopic pump 50 extends, it will cause the square mounting block 51 and the triangular base block 52 to detach, thereby causing the fixed base plate 11 to detach from the casting mold frame 10.
[0045] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The casting mold frame 10 has a U-shaped sealing groove 53 on one side of the fixed base plate 11. A U-shaped sealing strip 54 is welded and fixed to the fixed base plate 11, and the U-shaped sealing strip 54 matches the U-shaped sealing groove 53. The U-shaped sealing strip 54 moves in the U-shaped sealing groove 53. The sealing performance of the mold box is improved by the staggered cooperation between the U-shaped sealing strip 54 and the U-shaped sealing groove 53.
[0046] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The casting mold frame 10 and the fixed base plate 11 are closed and locked. Workshop personnel or robots push the fixed base plate 11 horizontally into the side slot of the casting mold frame 10. The fixed base plate 11 is inserted into the triangular base block 52 through the square mounting block 51. The hydraulic telescopic pump 50 fixedly installed at the bottom of the casting mold frame 10 is started. The fixed base plate 11 and the casting mold frame 10 are sealed and fitted together through the triangular base block 52 and the square mounting block 51. During the sealing process, it is ensured that the U-shaped sealing strip 54 on the side of the fixed base plate 11 can smoothly enter the U-shaped sealing groove 53 on the side of the casting mold frame 10, so as to achieve a complete and sufficient sealing connection between the fixed base plate 11 and the casting mold frame 10.
[0047] Working principle: First, the casting mold frame 10 and the fixed base plate 11 are closed and locked. Workshop personnel or a robot push the fixed base plate 11 horizontally into the side slot of the casting mold frame 10. The fixed base plate 11 is inserted into the triangular base block 52 through the square mounting block 51. The hydraulic telescopic pump 50, which is fixedly installed at the bottom of the casting mold frame 10, is started. Through the triangular base block 52 and the square mounting block 51, the fixed base plate 11 and the casting mold frame 10 are sealed and fitted together. During the sealing process, it is ensured that the U-shaped sealing strip 54 on the side of the fixed base plate 11 can smoothly enter the U-shaped sealing groove 53 on the side of the casting mold frame 10, so as to achieve the sealing between the fixed base plate 11 and the casting mold frame 10. The connection between the two parts is completely and fully sealed. Then the interlocking and fixing components are activated. The hydraulic telescopic rod 42 on the support plate 40 extends upward and pushes the push-pull block 47 upward. The movement of the push-pull block 47 is transmitted to the first connecting plate 45 through the second connecting plate 48, so that it rotates around the support shaft 44 on the connecting plate 43 like a lever. At the same time, the push-pull block 47 also pulls the lower end of the arc-shaped interlocking block 46 directly through the third connecting plate 49. The combination of these two actions makes the arc-shaped interlocking block 46 like a claw, tightly pressing it onto the wedge-shaped bottom block 15 on the top of the fixed base plate 11, thus completing the mechanical reinforcement and locking between the fixed base plate 11 and the top of the casting mold frame 10.
[0048] After the casting mold box is sealed and assembled, an automatic spraying device is used to evenly spray a layer of release agent on its surface. The casting mold box is then fed into the concrete hopper via conveyor track 14. The slurry, which is mixed evenly according to the formula, is injected into the closed mold box through a casting mixer. The speed and height of the pouring process need to be controlled to prevent splashing and the inclusion of too many large air bubbles. After pouring, the full mold box is smoothly transported into the settling chamber by conveyor track 14. In the settling chamber, aluminum powder reacts chemically with alkaline substances to produce hydrogen gas, forming uniform and fine air bubbles, which cause the slurry volume to expand rapidly until it fills the entire mold box. Subsequently, the slurry gradually thickens and solidifies, forming a green body with a certain initial strength. During the movement and transportation process, the full mold box is conveyed by rollers. 13 moves on the conveying track 14. Workshop personnel start the bidirectional motor 22 at the bottom of the mold frame. The motor drives the two screws 23 to rotate, causing the moving blocks 26 on the screws 23 to move to both sides. The moving blocks 26 transmit force to the limiting side plates 30 hinged to the fixed base 21 through the push rod 27. The limiting side plates 30 unfold outward with the cooperation of the push rod 27 and the hinge rod 25. The limiting rollers 33 installed on the limiting side plates 30, under the preload of the telescopic spring 32, steadily abut against the inner walls of both sides of the conveying track 14. In this way, the entire casting mold frame 10 is restricted to the center of the track during the movement, effectively suppressing lateral swaying and vibration, protecting the internal unformed billet structure, and avoiding bubbles and internal cracks caused by swaying.
[0049] Finally, after the billet has initially hardened in the static chamber, the mold box enters the demolding station. The mold box flips over, turning the fixed base plate 11 to the bottom and placing it on the conveyor belt. Then, the hydraulic telescopic pump 50 extends, causing the triangular base block 52 of the hydraulic telescopic pump 50 to disengage from the square mounting block 51 on the fixed base plate 11. Then, the hydraulic telescopic rod 42 of the interlocking fixing assembly retracts, driving the arc-shaped interlocking block 46 to rotate upward and retract through the linkage mechanism, releasing the pressure on the wedge-shaped base block 15. At this point, the fixed base plate 11 is completely separated from the casting mold frame 10, and the fixed base plate 11 is horizontally transported away by the conveyor belt. The fixed base plate 11 carries the complete billet into the next cutting process, while the empty casting mold frame 10 can be removed for cleaning, spraying release agent, and starting the next production cycle. At the same time, the limiting side plate 30 in the expansion limiting assembly retracts, ready for the next movement.
[0050] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
