Description
Technical Field
[0001] This utility model relates to the field of steam sand aerated concrete block technology, and in particular to a demolding device for steam sand aerated concrete blocks. Background Technology
[0002] In the industrial production of steam-cured aerated concrete blocks, demolding is a crucial step connecting block forming with subsequent curing and processing, directly affecting production efficiency and product qualification rate. Currently, block forming molds mostly consist of a base plate, two side plates, and partitions. After forming, a demolding device is needed to separate the block from the mold. Current demolding devices for steam-cured aerated concrete blocks have the following shortcomings: After demolding, concrete debris and adhesive residue often remain on the surface of the base plate. Existing equipment requires manual cleaning with a scraper or reliance on independent cleaning equipment. Cleaning a single base plate takes about 1-2 minutes. Manual cleaning is prone to scratching the surface of the base plate due to uneven force, which affects the flatness of the next batch of blocks. If the cleaning is not thorough, the residue mixed with the new material will also cause defects such as pitting and bulging on the surface of the blocks. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a demolding device for steam-sand aerated concrete blocks, which solves the problem that manual cleaning can easily scratch the surface of the base plate due to uneven force, affecting the flatness of the next batch of blocks. If the cleaning is not thorough, the residue mixed with the new material can also cause defects such as pitting and bulging on the surface of the blocks.
[0004] To achieve the above objectives, this utility model provides the following technical solution: A demolding device for steam sand aerated concrete blocks includes a demolding platform, an installation frame fixedly installed on the top of the demolding platform, a base plate provided on the top of the demolding platform, side plates provided on both sides of the top of the base plate, and multiple oppositely arranged partitions fixedly installed on opposite sides of the two side plates.

[0005] Preferably, the driving component includes: Two sprockets are respectively rotatably mounted on both sides of the top of the demolding table. A chain is fitted between the teeth of the two sprockets. A motor is fixedly mounted on the side wall of the demolding table. The output end of the motor is fixedly connected to the shaft end of one of the sprockets.
[0006] Preferably, the lifting assembly includes: The second hydraulic cylinder is fixedly installed at the bottom of the demolding table. The output end of the second hydraulic cylinder passes through the demolding table and is fixedly connected to the base plate. Multiple guide rods are fixedly installed at the bottom of the base plate, and the multiple guide rods pass through and are slidably connected to the demolding table.
[0007] Preferably, the slag removal component includes: The scraper is installed through and slidably on the bottom of the crossbeam.

[0024] in: Basic load-bearing components Demolding table 1: A horizontally set rectangular metal platform that serves as the supporting base for the entire device. Its top plane is used to install various functional components, and its bottom is fixed to the ground by a bracket to ensure overall stability.
[0025] Mounting bracket 2: It is fixedly installed on the top edge of the demolding table 1 and has a table-shaped frame structure (composed of four vertical rods and a plate frame). The bottom ends of the vertical rods are welded to the top of the demolding table 1 and the plate frame is used to support the rotational connection of the side plate 5.
[0026] mold components Base plate 4: It is a rectangular metal plate horizontally set at the top center of the demolding table 1, serving as the bottom mold for block forming; its top surface is smooth (reducing block adhesion), and the edge near the scraper 10 has a 45° chamfer (facilitating scraper transition); the bottom is connected to the lifting assembly and can be raised and lowered in the vertical direction.
[0027] Side plates 5: There are two of them, symmetrically distributed on both sides of the base plate 4, in the form of rectangular plates; their top edges are rotatably connected to the plate frame of the mounting bracket 2 via hinges (they can be flipped around the horizontal axis), and their bottom edges cooperate with the two side edges of the base plate 4 to form closed mold sides; Partition 15: Multiple partitions 15 are fixedly installed on the inner sides of the two side plates 5 (i.e. the side facing the bottom plate 4). The partition 15 is a rectangular thin sheet, set in the vertical direction, and the two partitions 15 are opposite to each other. It is used to divide the inside of the mold into multiple independent cavities to realize the one-time molding of multiple blocks.
[0028] Driver components Used to drive the horizontal movement of the slag removal component, specifically including: Sprockets 8: There are two sprockets, both of which are toothed metal wheels. They are mounted on both ends of the top of the demolding table 1 (along the length direction) via bearings. The shafts of the two sprockets 8 are at the same horizontal height and the teeth face the same direction.
[0029] Chain 6: A closed metal chain, fitted between the teeth of two sprockets 8 to form a chain drive mechanism; one link of chain 6 is fixedly connected to the crossbeam 11, and the crossbeam 11 is moved by the cyclic movement of the chain.
[0030] Motor 7: A servo motor, fixedly installed on the side wall of the demolding table 1 (near one of the sprockets 8), its output shaft is fixedly connected to the central shaft of the sprocket 8 through a coupling, providing power for the rotation of the sprocket 8.
[0031] Lifting components The control for vertical lifting of the base plate 4 includes: The second hydraulic cylinder 13 is fixedly installed at the bottom center of the demolding table 1. Its cylinder body is bolted to the bottom of the demolding table 1. The piston rod passes vertically upward through the through hole of the demolding table 1 and its top end is welded and fixed to the bottom center of the base plate 4. The base plate 4 is driven to rise and fall by the extension and retraction of the piston rod.
[0032] Guide rods 14: There are multiple (preferably 4), all of which are cylindrical metal rods, evenly distributed along the circumference of the second hydraulic cylinder 13; the top of the guide rod 14 is welded and fixed to the bottom of the base plate 4, and the bottom end passes through the guide hole on the demolding table 1 and slides with it, which is used to limit the horizontal displacement of the base plate 4 and ensure the stability of the lifting process.
[0033] Slag removal components Used for cleaning residue from the top of the base plate 4 after demolding, specifically including: Slide rail 9: There are two of them, both of which are long strip-shaped metal guide rails, which are fixed parallel to each other on both sides of the top of the demolding table 1 (one of the slide rails 9 is located between the base plate 4 and the sprocket 8). Its length direction is consistent with the movement direction of the chain 6, and it is used to support the sliding of the crossbeam 11.
[0034] Crossbeam 11: A horizontally positioned metal rod with two ends slidably connected to two slide rails 9 (movable along the length of the slide rails), and one end fixedly connected to a link of chain 6, moving synchronously with chain 6.
[0035] Scraper 10: It is triangular (L-shaped in cross-section), with a blade-shaped bottom (to enhance the slag scraping effect) and two cylindrical protrusions at the top; the protrusions pass through the through holes on the crossbeam 11 and slide with it to realize the up and down floating of the scraper 10.
[0036] Spring 12; there are two springs, which are respectively sleeved on the outside of the two cylindrical protrusions on the top of the scraper 10; the top end of the spring 12 abuts against the bottom of the crossbeam 11, and the bottom end abuts against the top of the scraper 10, and is fixed by welding, so as to provide downward elastic force for the scraper 10 and make its bottom stick tightly to the surface of the base plate 4.
[0037] Auxiliary connection structure First hydraulic cylinder 3: There are two of them, which are installed on the outside of the two side plates 5 (the side away from the bottom plate 4); the outer wall of the cylinder body is rotatably connected to the top of the mounting frame 2 through a metal shaft, and the top of the piston rod is rotatably connected to the middle outer side of the side plate 5 through a hinge. The extension and retraction of the piston rod drives the side plate 5 to rotate around the hinge of the mounting frame 2 (to realize the opening and closing of the mold side).
[0038] Working principle: The first step is to control the second hydraulic cylinder 13 to retract, causing the base plate 4 to begin to descend until the top of the base plate 4 is higher than the bottom of the scraper 10. At this point, the bottom height of the scraper 10 is level with the height of the middle of the chamfer on one side of the base plate 4. Then, by controlling the two first hydraulic cylinders 3 to retract, the two side plates 5 and the partitions 15 on both sides are flipped to the sides of the concrete, thereby quickly demolding multiple steam sand aerated concretes. During the lifting and lowering of the base plate 4, the dynamic stability can be improved by adding guide rods 14.
[0039] The second step involves transferring all the steam-cured aerated concrete from the base plate 4. The motor 7 is then started, rotating one of the sprockets 8. Through the transmission of the chain 6 and the other sprocket 8, the chain 6 drives the crossbeam 11 along the slide rail 9 towards the other end of the base plate 4. When the bottom of the scraper 10 reaches the chamfer at one end of the base plate 4, the bottom of the scraper 10 slides diagonally upwards along the chamfer. Simultaneously, the scraper 10 and the crossbeam 11 compress the spring 12 until the scraper 10 reaches the top plane of the base plate 4. The pressure applied to the scraper 10 by the spring 12 ensures that the scraper 10 adheres tightly to the top plane of the base plate 4, thus cleaning the residue on the top of the base plate 4 more thoroughly. During the movement of the scraper 10 along the top of the base plate 4, the triangular design of the scraper 10 allows the residue on the top of the base plate 4 to be collected at the center of the scraper 10, and then pushed along the top plane of the base plate 4 to the other end, thereby achieving automatic cleaning of the top of the base plate 4.
[0040] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
