[0002] In the field of construction engineering, the mechanical properties of concrete are a key indicator for measuring its quality, and concrete test blocks, as an important carrier for testing concrete performance, directly affect the accuracy of test results due to their molding quality. To efficiently and systematically prepare concrete test blocks, concrete test block molding molds have emerged.
[0003] Currently, to improve the efficiency of concrete specimen preparation and meet the needs of batch testing, many existing concrete specimen molding molds are equipped with internal partitions. These partitions divide the interior of the mold into multiple independent molding slots, allowing operators to pour and mold multiple concrete specimens at once, significantly improving work efficiency. However, in most of these molds on the market, the partitions are fixed structures inside the mold, and their position and spacing cannot be adjusted according to actual needs. This means that when different sizes of concrete specimens need to be prepared, the corresponding molds must be replaced, which not only increases costs but also requires additional storage space to store molds of various sizes, causing considerable inconvenience in actual operation.
[0004] To address the problems raised in the background art, those skilled in the art have proposed a concrete test block molding mold. Utility Model Content

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0023] As attached Figure 1 To be continued Figure 4 As shown:
[0024] This utility model provides a concrete test block molding mold, including a mold box 1, a partition component 2 is provided inside the mold box 1, and a limiting component 3 is provided on both the front and rear sides of the mold box 1 to limit the position of the partition component 2.
[0025] refer to Figure 3 and Figure 4 The partition component 2 includes a partition 21 that is slidably disposed inside the mold box 1. A horizontal plate 22 is disposed on the upper part of the partition 21, and a handle 23 is disposed on the upper part of the horizontal plate 22.
[0026] The mold box 1 can be divided into multiple forming areas by multiple partitions 21. When making concrete test blocks, multiple concrete test blocks can be poured and formed at one time by using multiple forming areas. Furthermore, by changing the number and spacing of the partitions 21, it can be adapted to the production needs of test blocks of different sizes and specifications without changing the mold.
[0027] refer to Figure 2 The limiting component 3 includes two connecting rods 31 arranged symmetrically on the outside of the mold box 1. A connecting plate 32 is slidably arranged on the connecting rods 31. A limiting plate 33 is arranged on the upper part of the two connecting plates 32. A plurality of limiting holes 34 are opened on the limiting plate 33.
[0028] refer to Figure 3 Both the front and rear sides of the horizontal plate 22 are provided with insertion rods 24 that are adapted to the limiting holes 34. The end of the insertion rod 24 away from the horizontal plate 22 is inserted into the corresponding limiting hole 34.
[0029] refer to Figure 1 A threaded rod 4 is rotatably provided on the front side of the mold box 1, and a movable plate 5 is threaded on the threaded rod 4. The upper part of the movable plate 5 is connected to the bottom of the front limiting plate 33.
[0030] refer to Figure 2 A housing 6 is provided on the left side of the mold box 1. A connecting shaft 7 is rotatably provided inside the housing 6. A gear 8 is provided on the outside of the connecting shaft 7. A toothed plate 9 is provided on each of the two connecting plates 32 on either side, and the two toothed plates 9 are arranged opposite each other. The side of the toothed plate 9 away from the connecting plate 32 penetrates into the interior of the housing 6 and meshes with the gear 8.
[0031] When it is necessary to adjust the size of the forming area inside the mold box 1, the operator can rotate the threaded rod 4. Under the threaded engagement of the threaded rod 4 and the moving plate 5 and the guiding action of the front connecting rod 31, the moving plate 5 drives the front connecting plate 32 and the front limiting plate 33 to move forward in the horizontal direction. When the front connecting plate 32 moves, it drives the front toothed plate 9 to move synchronously. The front toothed plate 9 drives the rear toothed plate 9 to move in the opposite direction through the meshing transmission with the gear 8. Then, through the rear connecting plate 32, it drives the rear limiting plate 33 to move backward synchronously. As the front and rear limiting plates 33 separate in the opposite direction, the insert rod 24 gradually comes out from the corresponding limiting hole 34. At this time, the limiting and locking state of the horizontal plate 22 and the partition plate 21 is released. The operator can move the position of the existing partition plate 21 or increase or decrease the number of partition plates 21 by the handle 23, thereby flexibly adjusting the size of the forming area inside the mold box 1.
[0032] After the partition 21 is adjusted to the appropriate position, the worker rotates the threaded rod 4 in the opposite direction. Under the meshing transmission action of the gear 8 and the front and rear toothed plates 9, the front and rear limiting plates 33 move closer to each other until the insertion rod 24 is re-inserted into the corresponding limiting hole 34, thus completing the limiting and locking of the horizontal plate 22 and the partition 21, ensuring that the partition 21 remains stable during the concrete pouring and molding process. After the concrete test block is formed, the limiting of the horizontal plate 22 is released according to the above adjustment steps. The worker can take the partition 21 out of the mold box 1 through the handle 23, which facilitates the sampling of the formed concrete test block.
[0033] refer to Figure 1 , Figure 3 and Figure 4 The mold box 1 has guide grooves 10 on both the front and rear sides of the upper part. A guide block 11 is slidably arranged in the guide groove 10, and the upper part of the guide block 11 is connected to the bottom of the horizontal plate 22.
[0034] refer to Figure 1 and Figure 3 The mold box 1 has scale lines on both the front and back sides of the upper part.
[0035] When the staff moves the horizontal plate 22 by the handle 23 to adjust the position of the partition 21, since the horizontal plate 22 is connected to the partition 21 and the guide block 11 at the bottom of the horizontal plate 22 slides along the guide groove 10 of the mold box 1, the edge or bottom of the horizontal plate 22 forms a corresponding reference with the scale line on the upper part of the mold box 1. The staff can intuitively and accurately judge the current position of the partition 21 and the distance between adjacent partitions 21 by observing the scale line value aligned with the edge of the horizontal plate 22. This allows the staff to quickly adjust the size of the forming area to the target specification, avoiding the size deviation caused by adjustment based solely on experience. This further improves the accuracy and efficiency of preparing concrete test blocks of different specifications and provides a basic guarantee for the accuracy of subsequent test block testing.
[0036] Working principle: When making concrete test blocks, multiple forming zones are formed inside the mold box 1 by multiple sliding partitions 21, allowing multiple concrete test blocks to be cast and formed at one time. The number and spacing of the partitions 21 can be adjusted to meet the needs of making test blocks of different sizes. When it is necessary to adjust the size of the forming zone inside the mold box 1, the operator rotates the threaded rod 4. Under the threaded engagement of the threaded rod 4 and the moving plate 5 and the guiding action of the front connecting rod 31, the moving plate 5 drives the front connecting plate 32 and the limiting plate 33 to move forward. At the same time, the front connecting plate 32 drives the toothed plate 9 to move. Through the meshing transmission of the gear 8 in the housing 6 and the front and rear toothed plates 9, the rear limiting plate 33 moves backward synchronously, realizing the reverse separation of the front and rear limiting plates 33. This allows the inserts 24 on the front and rear sides of the horizontal plate 22 to disengage from the limiting holes 34 of the limiting plate 33, releasing the limitation on the horizontal plate 22 and the partitions 21. The linkage structure of plate 8 and toothed plate 9 can unlock all partitions 21 at once, avoiding the tedious process of operating each partition 21 individually, greatly reducing adjustment steps and operation time. At this time, the staff can move the partitions 21 or increase or decrease the number of partitions 21 by using handle 23. During the movement of the partitions 21, the staff can intuitively and accurately judge the position and spacing of the partitions 21 by referring to the scale lines on the upper part of the mold box 1, ensuring the accurate size of the forming area. After the position of the partitions 21 is adjusted, the threaded rod 4 is rotated in the opposite direction. Through the transmission of gear 8 and toothed plate 9, the front and rear limiting plates 33 are brought closer to each other, allowing the insert rod 24 to be re-inserted into the limiting hole 34, completing the limiting and locking of the horizontal plate 22 and partitions 21, ensuring the stability of the partitions 21 during the concrete pouring and forming process. After the test block is formed, the limiting is released according to the above steps, and the partitions 21 are removed by using handle 23, making it convenient to sample the formed test block.
