Description

Technical Field

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

[0002] Concrete blocks on the market generally include ordinary concrete small hollow blocks, lightweight aggregate concrete small hollow blocks, autoclaved aerated concrete blocks, and foamed concrete blocks. Concrete blocks have advantages such as high strength, light weight, easy construction, good wall surface flatness, and high construction efficiency. Concrete blocks are an artificial stone material made by mixing cement, coarse aggregate (crushed stone or pebbles), fine aggregate (sand), admixtures, and water, and then hardening the mixture. Sand and stone act as a skeleton in the concrete and inhibit cement shrinkage; cement and water form cement paste, which coats the surface of the coarse and fine aggregates and fills the gaps between them. Before hardening, the cement paste acts as a lubricant, giving the concrete mixture good workability; after hardening, it binds the aggregates together to form a strong whole. Most existing concrete block molds are not adjustable, and one mold can only produce one size of concrete block. Producing concrete blocks of different sizes requires a large number of molds, resulting in low efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a mold for concrete blocks. By adjusting the distance between the baffles and the distance between the side plates, the size of the entire mold can be changed, thus solving the problem that the mold cannot be adjusted to produce concrete blocks of different sizes.

[0004] This utility model is achieved through the following technical solution:

[0005] This utility model is a mold for concrete blocks, including a base plate, a baffle plate and a side plate, and a groove is provided on the base plate;

[0006] Two locking blocks are provided at the bottom of the baffle, and the locking blocks are installed in the slide groove. Two fixing blocks are provided on both sides of the baffle, and each fixing block has a first threaded hole. A threaded rod is installed in the first threaded hole. A groove is provided at the top of the baffle.

[0007] A protrusion is provided on one side of the side plate, and a slot is provided on the protrusion. The slot is slidably engaged with the top of the baffle. A groove is provided on one side of the side plate, and a horizontal plate is installed in the groove.

[0008] Furthermore, a second threaded hole is provided on the protrusion, and a bolt is fitted into the second threaded hole.

[0009] Furthermore, a through hole is provided on one side of the inner wall of the groove, through which the bolt passes and engages with the second threaded hole.

[0010] Furthermore, there are two baffles, and two side plates are installed on each baffle, with both ends of the horizontal plate extending into the slots on the side plates respectively.

[0011] Furthermore, the locking block is embedded inside the stop block, the bottom surface of the inner wall of the stop block is fixedly connected to one end of the spring, and the other end of the spring is fixedly connected to the locking block.

[0012] This utility model has the following beneficial effects:

[0013] This invention adjusts the width of the produced concrete block by twisting the threaded rod to adjust the distance between the two baffles, and adjusts the length of the produced concrete block by moving the protrusion in the groove. By adjusting the length and width, the mold can produce concrete blocks of different specifications. The fixing block is kept in contact by the spring to prevent the chute from being blocked by concrete, which would prevent the baffles on both sides from moving during demolding and cause demolding difficulties.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0020] 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.

[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 Figure 1-4 This utility model provides a technical solution: a mold for concrete blocks, including a base plate 1, on which a groove 101 is provided; two locking blocks 201 are provided at the bottom of a baffle 2, and the locking blocks 201 are installed in the groove 101; two fixing blocks 202 are provided on both sides of the baffle 2, and each fixing block 202 is provided with a first threaded hole 203, in which a threaded rod 3 is installed; a groove 204 is provided at the top of the baffle 2; the locking blocks 201 are embedded in the baffle block 206; the bottom surface of the inner wall of the baffle block 206 is fixedly connected to one end of a spring 207; and the other end of the spring 207 is fixedly connected to the locking blocks 201.

[0023] In this embodiment, the distance between the two baffles 2 is adjusted by twisting the threaded rod 3, thereby adjusting the width of the produced concrete block. The two fixing blocks 202 installed at the bottom of the baffle 2 are kept in contact under the action of the spring 207 to prevent the chute 101 from being blocked by concrete, which would prevent the baffles 2 on both sides from moving during demolding and cause demolding difficulties.

[0024] A protrusion 401 is provided on one side of the side plate 4. A slot 402 is provided on the protrusion 401. The slot 402 is slidably engaged with the top of the baffle 2. A groove 404 is provided on one side of the side plate 4. A horizontal plate 5 is installed in the groove 404. A second threaded hole 403 is provided on the protrusion 401. A bolt 6 is fitted in the second threaded hole 403. There are two baffles 2. Two side plates 4 are installed on each of the two baffles 2. The two ends of the horizontal plate 5 extend into the grooves 404 on the two side plates 4 respectively.

[0025] In this embodiment, the side plate 4 is snapped onto the baffle 2 by the protrusion 401. By moving the protrusion 401 in the groove 204, the length of the produced concrete block is adjusted. When the side plate 4 moves to the appropriate position, the side plate 4 is fixed by manually turning the bolt 6 to prevent the side plate 4 from moving during the pouring process and causing errors in the pouring of concrete blocks.
