Description

Technical Field

[0001] This utility model relates to the field of concrete block production mold technology, and in particular to a mold cleaning device for autoclaved aerated concrete block production. Background Technology

[0002] The molds used in the production of autoclaved aerated concrete (AAC) blocks are key equipment for ensuring the formation of the blocks. They typically consist of a mold frame and a base plate, forming a rectangular frame structure with various common specifications. During block production, material residue remains on the mold surface. This residue not only affects the adhesion of material during subsequent pours, leading to quality problems such as dimensional deviations and surface defects, but also causes mold damage due to hardened material eroding the mold, shortening its lifespan and hindering demolding, thus reducing production efficiency. Therefore, to ensure product quality, extend mold life, and improve production efficiency, a cleaning device must be installed to effectively clean the molds.

[0003] Most mold cleaning devices typically involve removing the mold frame and then moving the mold base plate along with the conveyor. During this movement, the top blade scrapes away impurities from the mold base plate, while the mold frame's inner wall is scraped by an electric push rod driven by a scraper. However, during the cleaning process, the bottom of the mold frame contacts the supporting base plate, creating space constraints and making it difficult to effectively clean the bottom of the inner wall of the mold frame, thus increasing the difficulty of cleaning.

[0004] Therefore, it is necessary to provide a new mold cleaning device for autoclaved aerated concrete block production to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a mold cleaning device for the production of autoclaved aerated concrete blocks.

[0006] This utility model provides a mold cleaning device for autoclaved aerated concrete (AAC) block production, comprising: a supporting base plate, a scraper, a limiting component, a fixing component, and a baffle. A mold frame is slidably connected to the top groove of the supporting base plate. Receiving blocks are symmetrically fixedly connected to the top of the supporting base plate. A one-way threaded rod is rotatably connected inside one of the receiving blocks, and a fixing rod is fixedly connected inside the other receiving block. A motor is fixedly connected to the top of the receiving block with the one-way threaded rod. A carrying plate is fixedly connected to the top of the two receiving blocks. An electric push rod is fixedly connected to the top of the carrying plate. A receiving plate is fixedly connected to the drive end of the electric push rod. Connecting blocks are slidably connected to the outer and inner walls of the receiving plate. A scraper is fixedly connected to the far side of each of the connecting blocks. Multiple limiting components are provided inside the receiving plate. Fixing components are installed inside the close side of each of the two receiving blocks. A baffle is fixedly connected to one side of the top of the supporting base plate.

[0007] Preferably, the limiting component includes a sliding hole, a sliding rod is slidably connected inside the sliding hole, a strong spring is sleeved on the outside of the sliding rod, and four limiting plates are fixedly connected to the opposite sides of the plurality of sliding rods.

[0008] Preferably, the fixing component includes sliding blocks, and two bidirectional threaded rods are rotatably connected to the interior of adjacent sides of the two sliding blocks. Two moving blocks are externally threaded to the bidirectional threaded rods. Connecting rods are rotatably connected to the interior of adjacent sides of the multiple moving blocks. Two connecting blocks are rotatably connected to the exterior of adjacent sides of the multiple connecting rods. Two locking blocks are fixedly connected to adjacent sides of the two connecting blocks. Two locking grooves are symmetrically opened on both sides of the mold frame.

[0009] Preferably, the interior of one of the sliding blocks is slidably connected to the exterior of the fixed rod, and the interior of the other sliding block is threadedly connected to the exterior of the one-way threaded rod.

[0010] Preferably, one end of the mold frame is in contact with the surface of the baffle, and the drive end of the motor is fixedly connected to one end of the one-way threaded rod.

[0011] Preferably, limiting holes are provided on all four sides of the receiving plate, and the outer side of the scraper contacts the inner wall of the mold frame.

[0012] Preferably, the external sliding connection of the moving block is inside one side of the sliding block, and the external connection of the engaging block and the internal connection of the engaging groove are engaged.

[0013] Preferably, one end of the bidirectional threaded rod is fixedly connected to a rotating disk, and multiple scrapers are arranged in an alternating manner.

[0014] Compared with related technologies, the mold cleaning device for autoclaved aerated concrete block production provided by this utility model has the following beneficial effects:

[0015] By rotating the rotating disk, the bidirectional threaded rod is driven to rotate, causing the moving block to engage with the locking block and locking groove, thus firmly fixing the mold frame and preventing it from moving during cleaning, ensuring stable cleaning. Then, the motor is started, driving the unidirectional threaded rod to rotate. The sliding block uses the locking structure to move the mold frame upward to a suspended state, overcoming the space limitation caused by the contact between the bottom of the mold frame and the supporting base plate. This facilitates cleaning of the bottom of the inner wall of the mold frame, effectively reducing the difficulty of cleaning and improving the comprehensiveness of cleaning.

[0016] The electric push rod drives the receiving plate to move the scraper to contact the inner wall of the mold frame for cleaning. During cleaning, the scraper causes the connecting block to retract, which causes the limiting plate to move the sliding rod. This compresses the strong spring and generates a rebound force, ensuring that the scraper fits tightly against the inner wall of the mold frame, effectively removing impurities and reducing block quality problems caused by impurity residue.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] Please see Figures 1 to 4A mold cleaning device for autoclaved aerated concrete (AAC) block production includes: a supporting base plate 1, which serves as the foundation structure of the entire device; a mold frame 2 slidably connected to a groove at the top of the supporting base plate 1, allowing the mold frame 2 to slide smoothly into the groove. The dimensions of the groove are precisely calculated to ensure a tight fit for the mold frame 2, providing a stable starting point for subsequent cleaning operations; a baffle, fixedly connected to one side of the top of the supporting base plate 1, with one end of the mold frame 2 contacting the surface of the baffle, serving to limit the position of the sliding mold frame 2, ensuring that one end of the mold frame 2 fits tightly against the baffle surface, preventing displacement deviation of the mold frame 2 during subsequent operations; a baffle fixedly connected to one side of the top of the supporting base plate 1; and symmetrically fixedly connected to the top of the supporting base plate 1 are receiving blocks 3, one receiving block 3 having a rotatably connected one-way threaded rod 4 inside, and the other receiving block 3 having a fixedly connected... There is a fixed rod 5. The two receiving blocks 3 not only serve to support and fix the subsequent structure, but also provide installation space for the one-way threaded rod 4 and the fixed rod 5. The top of the receiving block 3 on which the one-way threaded rod 4 is installed is fixedly connected to a motor 6. The drive end of the motor 6 is fixedly connected to one end of the one-way threaded rod 4. When the motor 6 starts, it can provide stable power output for the rotation of the one-way threaded rod 4. The top of the two receiving blocks 3 is fixedly connected to a carrying plate 7. The top of the carrying plate 7 is fixedly connected to an electric push rod 8. The drive end of the electric push rod 8 is fixedly connected to a receiving plate 9. Connecting blocks 10 are slidably connected to the outer and inner walls of the receiving plate 9.

[0025] Scraper 11 is fixedly connected to the opposite side of multiple connecting blocks 10. The multiple scrapers 11 are arranged in an alternating manner. This unique layout design allows the scrapers 11 to cover a wider area when cleaning the inner wall of the mold frame 2, avoiding cleaning dead corners. When the outside of the scraper 11 contacts the inner wall of the mold frame 2, it can scrape and clean the material impurities remaining on the inner wall.

[0026] The limiting components include multiple limiting components inside the receiving plate 9. Each limiting component includes a sliding hole 12, a sliding rod 13 slidably connected inside the sliding hole 12, and a strong spring 14 sleeved on the outside of the sliding rod 13. Four limiting plates 15 are fixedly connected to the opposite sides of the multiple sliding rods 13. Limiting holes 16 are opened inside all four sides of the receiving plate 9. The outside of the limiting plate 15 is slidably connected to the inside of the limiting hole 16. When the scraper 11 encounters impurities during the cleaning process, it will cause the connecting block 10 to retract, thereby allowing the limiting plate 15 to slide flexibly inside the limiting hole 16 and apply force to the sliding rod 13. While the sliding rod 13 slides smoothly inside the sliding hole 12, the strong spring 14 is compressed, thereby generating a rebound force. This rebound force can ensure that the scraper 11 always keeps in close contact with the inner wall of the mold frame 2.

[0027] The fixing components are installed inside the two adjacent sides of the receiving blocks 3. The fixing components include sliding blocks 17. The interior of one sliding block 17 is slidably connected to the exterior of the fixing rod 5, and the interior of the other sliding block 17 is threadedly connected to the exterior of the one-way threaded rod 4. The interior of the two adjacent sides of the two sliding blocks 17 is rotatably connected to a bidirectional threaded rod 18. The exterior of the bidirectional threaded rod 18 is threadedly connected to two moving blocks 19. When the bidirectional threaded rod 18 rotates, it can drive the two moving blocks 19 to move in the same or different directions. The exterior of the moving blocks 19 is slidably connected to the interior of one side of the sliding block 17. The interior of the adjacent sides of the multiple moving blocks 19 is rotatably connected to a connecting rod 20. The exterior of the multiple connecting rods 20 is rotatably connected to two connecting blocks 21. The adjacent sides of the two connecting blocks 21 are fixedly connected to two locking blocks 22. Two locking grooves 23 are symmetrically opened on both sides of the mold frame 2. The exterior of the locking blocks 22 is lockedly connected to the interior of the locking grooves 23. One end of the bidirectional threaded rod 18 is fixedly connected to a rotating disk 24.

[0028] The working principle of the mold cleaning device for autoclaved aerated concrete block production provided by this utility model is as follows:

[0029] The device operates efficiently and systematically when cleaning the molds used for autoclaved aerated concrete (AAC) block production. First, the mold frame 2 is smoothly slid into the groove at the top of the support base plate 1, ensuring a precise and perfect fit. Next, the operator rotates the rotating disc 24. As the disc rotates smoothly, the bidirectional threaded rod 18 begins to rotate stably inside the sliding block 17. Driven by the bidirectional threaded rod 18, the two moving blocks 19 slowly move towards each other, pushing the connecting block 21 to move synchronously via the connecting rod 20. This continues until the connecting block 21 drives the engaging block 22 into the engaging groove 23, completing one-way engagement. Then, the operator rotates another rotating disc 24, causing another set of engaging blocks 22 to also fit tightly into the engaging groove 23. At this point, the mold frame 2 is fixed to the support structure. Then, the motor 6 is started, and its powerful motor drives the unidirectional threaded rod 4 to rotate. At this time, the sliding block 17, with the tight engagement of the engaging blocks 22 and engaging groove 23, moves the mold frame 2 smoothly. At the same time, another sliding block 17 slides smoothly outside the fixed rod 5, providing stable support and guidance for the movement of the mold frame 2, so that the mold frame 2 can be steadily lifted upward and finally achieve a suspended state.

[0030] After the mold frame 2 is suspended in the air, the electric push rod 8 is activated. The electric push rod 8 pushes the receiving plate 9 to move slowly downwards, and the receiving plate 9 brings the connecting block 10 and the scraper 11 closer to the inner wall of the mold frame 2. When the scraper 11 contacts the inner wall of the mold frame 2 and begins to clean, as impurities obstruct the flow, the scraper 11 causes the connecting block 10 to retract. At this time, the limiting plate 15 slides flexibly inside the limiting hole 16, applying force to the sliding rod 13, so that the sliding rod 13 slides smoothly inside the sliding hole 12. During this process, the strong spring 14 is compressed, accumulating elastic potential energy and generating a rebound force, ensuring that the scraper 11 is always in close contact with the inner wall of the mold frame 2, thereby efficiently and thoroughly removing impurities from the inner wall.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
