Abstract
Description
Technical Field
[0001] This utility model relates to the field of aerated concrete block processing technology, specifically a rapid demolding device for autoclaved aerated concrete blocks. Background Technology
[0002] Autoclaved aerated concrete (AAC) bricks are a new type of lightweight wall material with closed micropores, made from fly ash, lime, and gypsum as the main raw materials, with the addition of an appropriate amount of a foaming agent. They are produced by pouring, static curing, cutting, and high-temperature autoclaving. They are mainly suitable for infill walls of frame and high-rise buildings, non-load-bearing partition walls, composite insulation layers of exterior walls of energy-saving buildings, and self-insulating exterior walls.
[0003] In the traditional autoclaved aerated concrete (AAC) block production process, workers may need to remove the bricks after production. However, the large amount of work involved in removing the bricks can reduce the demolding efficiency, increase the workload of workers, and waste human resources. In addition, after the AAC blocks are demolded, some impurities may remain on the surface of the mold. If they are not cleaned in time, they may affect the molding quality of the next batch of AAC blocks. Utility Model Content

Detailed Implementation
[0021] 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.
[0022] Please see Figures 1-6 A rapid demolding device for autoclaved aerated concrete blocks includes a device base 2, multiple support blocks 1 fixedly installed on the lower end face of the device base 2, a first mold mechanism 3 fixedly installed on the front and rear inner walls of the device base 2, a second mold mechanism 4 fixedly installed on the left and right inner walls of the device base 2, a third mold mechanism 7 fixedly installed on the inner bottom surface of the device base 2, a first support plate 5 fixedly installed on both sides of the device base 2, and a cleaning mechanism 6 fixedly installed on the upper end face of the two first support plates 5.
[0023] In the above structure, the support block 1 is used to support the device base 2. The first mold mechanism 3, the second mold mechanism 4 and the third mold mechanism 7 can be spliced together to form a complete aerated brick mold. The cleaning mechanism 6 is fixed to the upper end of the aerated brick mold by the first support plate 5.
[0024] In a preferred embodiment, the first mold mechanism 3 includes a first telescopic rod 301, a first mold plate 302 is fixedly installed on the front end face of the first telescopic rod 301, a first heat insulation layer 303 is fixedly installed on the front end face of the first mold plate 302, and a first slider 304 is fixedly installed on the lower end face of the first mold plate 302. The second mold mechanism 4 includes a second telescopic rod 401, a second mold plate 402 is fixedly installed on the front end face of the second telescopic rod 401, a second heat insulation layer 403 is fixedly installed on the front end face of the second mold plate 402, and a second slider 404 is fixedly installed on the lower end face of the second mold plate 402. The third mold mechanism 7 includes a fourth telescopic rod 701 and a support base 702. The upper end face of the support base 702 is provided with multiple sliding grooves 705. The upper end face of the fourth telescopic rod 701 is fixedly installed with the third mold plate 703, and the upper end face of the third mold plate 703 is fixedly installed with the third heat insulation layer 704.
[0025] In the above structure, the extension and retraction of the first telescopic rod 301 and the second telescopic rod 401 allow the first mold plate 302 and the second mold plate 402 to fit together with the third mold plate 703 to form a complete aerated concrete block mold. Then, the aerated concrete block is autoclaved. The first insulation layer 303, the second insulation layer 403, and the third insulation layer 704 are used to insulate the temperature flow during the aerated concrete block production process, preventing high temperatures from affecting the service life of the telescopic rods and thus increasing the lifespan of the device. After the aerated concrete block is formed, the first telescopic rod 301 and the second telescopic rod 401 retract, causing the first mold plate 302 and the second mold plate 402 to detach from the third mold plate 703, thus completing the demolding operation. Then, the fourth telescopic rod 701 extends and retracts to lift the finished aerated concrete block, making it easier for workers to remove the finished product and increasing the production efficiency of the aerated concrete block.
[0026] In a preferred embodiment, the cleaning mechanism 6 includes a second support plate 601, a third telescopic rod 606 fixedly installed on the lower end face of the second support plate 601, a connecting plate 605 fixedly installed on the lower end face of the third telescopic rod 606, a scraper 604 fixedly installed on the outer side of the connecting plate 605, and two vacuum cleaners 602 fixedly installed on the upper end face of the second support plate 601. Each of the two vacuum cleaners 602 has a telescopic air duct 603 fixedly installed at its output end.
[0027] In the above structure, the extension and retraction of the third telescopic rod 606 causes the scraper 604 to scrape the first mold plate 302 and the second mold plate 402, thereby cleaning the impurities on the surface of the first mold plate 302 and the second mold plate 402. The vacuum cleaner 602 collects the scraped impurities, thereby preventing the impurities from affecting the quality of the next batch of aerated concrete blocks.
[0028] The working principle is as follows: the extension and retraction of the first telescopic rod 301 and the second telescopic rod 401 allow the first mold plate 302 and the second mold plate 402 to fit together with the third mold plate 703 to form a complete aerated concrete block mold. Then, the scraper 604 in the cleaning mechanism 6 is used to clean the impurities on the surface of the first mold plate 302 and the second mold plate 402, and the vacuum cleaner 602 collects the scraped impurities, thus preventing impurities from affecting the quality of the aerated concrete block. After cleaning, the aerated concrete block forming operation is carried out. After the aerated concrete block is formed, the first telescopic rod 301 and the second telescopic rod 401 are retracted, causing the first mold plate 302 and the second mold plate 402 to detach from the third mold plate 703, thus completing the demolding operation. Then, the fourth telescopic rod 701 is extended and retracted to lift the finished aerated concrete block, making it easier for workers to remove the finished product and increasing the production efficiency of aerated concrete blocks.
