Description

Technical Field

[0001] This utility model relates to the field of concrete production technology, specifically to a concrete block casting mold. Background Technology

[0002] Concrete blocks are a type of masonry building material made primarily from cement, coarse and fine aggregates, sand, and gravel, through processes such as mixing with water, molding, and curing. They possess high strength, good durability, and fire resistance, and are widely used in load-bearing walls, non-load-bearing walls, and partition walls of buildings. Concrete block casting molds are devices used to shape concrete blocks; they are typically made of metal or plastic and have specified dimensions and shapes. When using the molds, concrete is poured in, and the blocks are demolded after solidification.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings.

[0028] Combined with appendix Figures 1-4 A concrete block casting mold mainly includes: a table 1, a scraping device 3, a mold frame one 5 and a mold frame two 6, and several connecting structures 7. Support parts 2 are fixedly connected to the four corners of the lower end of the table 1. The mold frame one 5 and the mold frame two 6 are movably connected to the upper end of the table 1. The mold frame one 5 and the mold frame two 6 are symmetrically arranged front and rear and used in conjunction. The mold frame one 5 is located in front of the mold frame two 6, and the mold frame one 5 and the mold frame two 6 can be assembled into a shape that meets the requirements for concrete block casting.

[0029] Then, the scraping device 3 includes a scraper 4 and a drive assembly. The drive assembly is used to drive the scraper 4 to move back and forth to scrape off excess concrete. Fixed rods 11 are fixedly connected to the four corners of the upper end of the table 1. The drive assembly includes two lead screws 12. The lead screws 12 are rotatably connected to the upper part of the front and rear fixed rods 11 on the same side. Threaded blocks 13 are threadedly connected to the lead screws 12. Moving plates 14 are fixedly connected to the sides of the threaded blocks 13 on both sides. The scraper 4 is fixedly connected to the lower end of the moving plate 14. The lower end of the scraper 4 is movably connected to the upper end of the mold frame 5 and the mold frame 6. A motor 15 is fixedly connected to the fixed rod 11 behind the lead screw 12. The output shaft of the motor 15 extends through the fixed rod 11 to its outside and is fixedly connected to the lead screw 12. A receiving frame 18 is fixedly connected to the lower end of the mold frame 5 and the mold frame 6 on the opposite side. The receiving frame 18 is used to collect the concrete scraped off by the scraper 4.

[0030] First, after assembling mold frame 5 and mold frame 6, and connecting them through connecting structure 7, concrete material is poured into the rectangular groove formed by mold frame 5 and mold frame 6. Then, the motors 15 on both sides simultaneously drive the lead screws 12 on both sides to rotate, driving the threaded blocks 13 on both sides to move back and forth, driving the moving plate 14 and scraper 4 to move synchronously, scraping off the excess concrete material on the upper part of mold frame 5 and mold frame 6, making the upper part of the concrete material flat, so as to ensure the quality of the subsequently formed blocks.

[0031] Specifically, sealing strips 16 are fixedly connected to the rear sides and bottom of mold frame 5, and sealing grooves 17 that cooperate with the sealing strips 16 are opened on the front sides and bottom of mold frame 6. Both sealing strips 16 and sealing grooves 17 are U-shaped. After assembly, they can ensure the sealing between mold frame 5 and mold frame 6. The connecting structure 7 includes a connecting rod 8 and a connecting block 9. The front end of the connecting block 9 is opened with a connecting groove 10. The connecting structure 7 is limited to the connecting groove 10 by the connecting rod 8, thus completing the connection between mold frame 5 and mold frame 6. The connecting rod 8 is fixedly connected to the upper and lower parts of the rear sides of mold frame 5, and the connecting block 9 is fixedly connected to the upper and lower parts of the front sides of mold frame 6. The connecting block 9 is slidably connected in the connecting groove 10.

[0032] Next, a limiting hole 19 is opened at the rear of the connecting block 9, and a through hole 20 is opened at the rear of the upper end of the connecting block 9. An insert rod 21 is provided in the through hole 20. The lower end of the insert rod 21 extends through the through hole 20 into the limiting hole 19. The lower end of the insert rod 21 is fixedly connected to a limiting block 22. The limiting block 22 is slidably connected to the inner wall of the limiting hole 19 and the through hole 20. The upper part of the insert rod 21 is movably connected to a limiting plate 23. The limiting plate 23 is fixedly connected to the upper part of the inner wall of the through hole 20. The upper end of the insert rod 21 extends through the limiting plate 23 and above it, and is fixedly connected to a pulling part 24. A spring 25 is sleeved on the outside of the insert rod 21. The upper and lower ends of the spring 25 are fixedly connected to the limiting plate 23 and the limiting block 22, respectively. Handles 26 are fixedly connected to the two disjointed sides of the mold frame 5 and the mold frame 6.

[0033] Before pouring, pull the pulling part 24 upwards. The insert rod 21 moves the limiting block 22 upwards, compressing the spring 25 during the process, until the limiting block 22 is completely disengaged from the limiting hole 19 and pulled into the through hole 20. Then, move the mold frame 5 and the mold frame 6 towards the same side, and the sealing strip 16 extends into the sealing groove 17 to complete the fit. At the same time, the connecting block 9 slides into the connecting groove 10 until the limiting hole 19 moves below the limiting block 22. Then, the pulling part 24 can be released. Under the action of the spring 25, the insert rod 21 and the limiting block 22 are reset, completing the limiting between the mold frame 5 and the mold frame 6, so as to facilitate the subsequent pouring steps.

[0034] After the pouring is completed, in order to remove the formed concrete block, first pull the pulling part 24 upward. The insert rod 21 drives the limiting block 22 to move upward. During the process, the spring 25 is compressed until the limiting block 22 is completely disengaged from the limiting hole 19 and pulled into the through hole 20. This releases the limitation between the connecting rod 8 and the connecting groove 10. By pulling the handle 26, the mold frame 1 5 and the mold frame 2 6 are separated. This is simple and quick, improves the demolding efficiency, and also facilitates cleaning the inside of the mold frame 1 5 and the mold frame 2 6.
