Description

Technical Field

[0001] This utility model relates to the field of aerated concrete block production technology, specifically to a surface embossing mold for autoclaved aerated concrete blocks. Background Technology

[0002] Autoclaved aerated concrete (AAC) blocks are porous concrete products made from fly ash, lime, cement, gypsum, slag, and other main raw materials, with the addition of appropriate amounts of foaming agents, regulators, and bubble stabilizers, through processes such as batching and mixing, pouring, static curing, cutting, and high-pressure autoclaving.

[0003] In the preparation of autoclaved aerated concrete (AAC) blocks, raw and auxiliary materials are mixed to form the required slurry, which is then poured into a mold and cured and solidified within the mold. However, existing molds for AAC blocks still have some defects:

[0004] Existing autoclaved aerated concrete (AAC) block molds can typically only produce AAC blocks with a smooth surface. If it is necessary to form patterns on the surface of the AAC block, the patterns need to be cut on the surface of the AAC block using cutting equipment at a subsequent cutting and processing station, which makes it relatively inconvenient to form patterns on the surface of autoclaved aerated concrete (AAC) blocks.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0028] Example: Figure 1-6As shown, this utility model provides a surface embossing molding mold for autoclaved aerated concrete (AAC) blocks, including a mold box 1. Both ends of the mold box 1 are fixedly provided with lifting lugs 11, and the lifting lugs 11 are provided with assembly holes 12. By providing the lifting lugs 11 and assembly holes 12, the mold box 1 is lifted and flipped during the demolding process for demolding the formed AAC blocks. The lower end face of the mold box 1 is equipped with several universal wheels 13. By providing the universal wheels 13, the mold box 1 can be easily moved by the operators when not in use. Embossing mechanisms 2 are provided on both sides of the mold box 1. By providing the embossing mechanisms 2, when the prepared slurry is injected into the interior of the mold box 1, after static curing and solidification at the static curing station, the sides of the AAC blocks can be embossed with patterns.

[0029] The embossing mechanism 2 includes a frame plate 21. Two frame plates 21 are provided and are symmetrically arranged on the side wall of the mold box 1. A U-shaped sealing strip 26 is fixedly provided on the outer side wall of the frame plate 21. The outer wall of the U-shaped sealing strip 26 is in contact with the side wall of the mold box 1. By providing the U-shaped sealing strip 26 on the frame plate 21, when the frame plate 21 moves horizontally in the mold box 1, the U-shaped sealing strip 26 can prevent the slurry between the two frame plates 21 from overflowing outward. Several pressure plates 22 can be detachably installed on the opposite sides of the two frame plates 21. Several stripes 23 are fixedly provided on one side of the pressure plate 22. By setting the pressure plate 22 and stripes 23, when the two pressure plates 22 are close to each other or far away from each other, aerated bricks of different widths can be produced. During the static curing and solidification process, the stripes 23 can form patterns on both sides of the aerated brick.

[0030] Two L-shaped fixing brackets 24 are fixedly installed on both sides of the mold box 1. A cylinder 25 is fixedly installed on the L-shaped fixing bracket 24. The piston end of the cylinder 25 is detachably installed on one side of the frame plate 21. By starting the cylinder 25, the telescopic end of the cylinder 25 extends and retracts, and the pressure plate 22 and stripe 23 can be moved horizontally in the mold box 1 through the frame plate 21.

[0031] The embossing mechanism 2 is equipped with a disassembly and assembly component 3, which includes several assembly bolts 32. One side of the frame plate 21 is provided with several recessed holes 31. The assembly bolts 32 are threadedly installed in the recessed holes 31. The side of the pressure plate 22 away from the stripes 23 is provided with several threaded holes 33. One end of the assembly bolts 32 is threadedly connected to the inner wall of the threaded holes 33. By setting the assembly bolts 32 and the threaded holes 33, the pressure plate 22 can be fixed to one side of the frame plate 21 through the threaded connection between the assembly bolts 32 and the threaded holes 33. The pressure plate 22 on one side of the frame plate 21 can be disassembled by reversing the operation, so as to facilitate the maintenance or replacement of the pressure plate 22 and the stripes 23.

[0032] The other end of the assembly bolt 32 is fixedly provided with a No. 1 hexagonal seat 34, which is located in the recess 31. By providing the No. 1 hexagonal seat 34, when a hexagonal wrench is placed on the No. 1 hexagonal seat 34, the assembly bolt 32 can be rotated by the hexagonal wrench.

[0033] The assembly / disassembly component 3 also includes several limiting blocks 35. The frame plate 21 has two insertion holes 36. An assembly base 37 is fixedly mounted on the piston end of the cylinder 25. The assembly base 37 is movably inserted into the inner wall of the insertion hole 36. The assembly base 37 has a limiting groove 38. The limiting blocks 35 are movably inserted into the inner wall of the limiting groove 38. By setting the limiting blocks 35, insertion holes 36, assembly base 37, and limiting groove 38, when the assembly base 37 enters the interior of the insertion hole 36, the frame plate 21 can be connected to the piston end of the cylinder 25. When the limiting blocks 35 slide vertically downwards to the limit... After entering the slot 38, the mounting base 37 can be limited and fixed, so that the frame plate 21 is fixed to the piston end of the cylinder 25. The frame plate 21 is provided with two cavities 39, and the limiting block 35 is slidably disposed in the cavity 39. Two threaded rods 43 are rotatably installed on the frame plate 21. One end of the threaded rod 43 is rotatably connected to one end of the limiting block 35. By setting the cavity 39 and the threaded rod 43, the limiting block 35 can be vertically raised and lowered in the cavity 39. By rotating the threaded rod 43, the threaded rod 43 can drive the limiting block 35 to be vertically raised and lowered in the cavity 39.

[0034] The inner wall of the cavity 39 is provided with two guide grooves 4. One end of the limiting block 35 is fixedly provided with two connecting plates 42. One end of the connecting plate 42 is fixedly provided with a guide block 41. The guide block 41 is slidably provided on the inner wall of the guide groove 4. By providing the guide groove 4, the guide block 41 and the connecting plate 42, the guide block 41 can slide vertically along the inner wall of the guide groove 4, so that the limiting block 35 can be vertically guided by the connecting plate 42. The other end of the threaded rod 43 is fixedly provided with a second hexagonal seat 44. By providing the second hexagonal seat 44, when the hexagonal wrench is placed on the second hexagonal seat 44, the threaded rod 43 can be rotated by the hexagonal wrench.

[0035] Working principle: In the process of preparing autoclaved aerated concrete blocks, before the grout is poured, the operator first starts four cylinders 25, which extend the piston end of the cylinders 25. The piston end of the cylinders 25 moves the pressure plate 22 horizontally through the frame plate 21, and adjusts the distance between the two pressure plates 22 so that the distance between the two pressure plates 22 meets the width requirements of the aerated concrete blocks to be prepared.

[0036] Subsequently, the prepared slurry is poured into the mold box 1. The slurry is located in the area between the two frame plates 21. After the pouring and vibration operation is completed, the mold box 1 is moved to the curing station and cured in the curing station. During the curing process, the action of multiple stripes 23 makes the aerated bricks have matching patterns on both sides, thus facilitating the forming of the surface pattern of the autoclaved aerated concrete bricks.

[0037] When maintenance or replacement of pressure plate 22 and stripe 23 is required, the operator first rotates threaded rod 43 by connecting hex wrench with No. 2 hex socket 44. Threaded rod 43 causes limit block 35 to rise vertically in cavity 39. Limit block 35 disengages from limit groove 38. Then push frame plate 21 away from cylinder 25 to disengage mounting base 37 from insertion hole 36. Then take frame plate 21 and pressure plate 22 out of mold box 1.

[0038] Subsequently, the operator uses a hex wrench connected to the hexagonal socket 34 to rotate the assembly bolt 32, disengaging the assembly bolt 32 from the threaded hole 33. This allows the pressure plate 22 to be disassembled, maintained, or replaced. By reversing the above steps, the replaced pressure plate 22 can be fixed onto the frame plate 21, and the frame plate 21 can be fixed onto the piston end of the cylinder 25. This facilitates the maintenance or replacement of the pressure plate 22, effectively improving the convenience of maintenance and replacement operations.

[0039] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0040] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
