DETAILED DESCRIPTION

[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application.

[0027] As Figures 1-8 shown, one embodiment of the present application proposes a concrete mold, which comprises a bottom plate 1 that can be enclosed and spliced to form a cavity, four stand columns 2 and four side plates 3. The bottom plate 1 is in a horizontal direction, and the stand columns 2 and the side plates 3 are both in a vertical direction. Four through holes 4 are constructed on the bottom plate 1, and the four through holes 4 are both in a vertical direction and are distributed in a rectangular array. A positioning block 5, two positioning grooves 6 and a limiting piece are provided on the stand column 2. The positioning block 5 is fixedly arranged at the bottom end of the stand column 2, and the positioning grooves 6 are arranged along the length direction of the stand column 2. The positioning block 5 is inserted and matched with the through hole 4. A locking piece for locking or unlocking the positioning block 5 is arranged on the bottom plate 1. The opposite sides of the side plate 3 are both provided with a positioning strip 7 that is inserted and matched with the positioning groove 6. The positioning strip 7 is in a vertical direction and is fixedly arranged on the side plate 3. The positioning strip 7 is limited or unlocked by the limiting piece. An adjusting plate 8 is movably arranged in the cavity. The adjusting plate 8 is in a vertical direction. The cavity is divided into two forming cavities by the adjusting plate 8. A locking part for the two side plates 3 is arranged on the adjusting plate 8. The adjusting plate 8 is locked or unlocked by the locking part.

[0028] In its initial state, this application is divided into several relatively independent components: a base plate 1, four uprights 2, four side plates 3, and an adjusting plate 8. This reduces the space occupied during storage. In use, the components are installed such that the base plate 1 is horizontal, the uprights 2 are vertical and overlap with the base plate 1, and the positioning blocks 5 are inserted into the through holes 4. The positioning blocks 5 are then locked in place by locking mechanisms to complete the installation of the uprights 2. This process is repeated to install the remaining three uprights 2. Finally, the side plates 3 are aligned vertically and overlap with the base plate 1. The base plate 1 overlaps with the side plate 3, which is located between two adjacent columns 2. The two positioning strips 7 on the opposite side of the side plate 3 are respectively inserted into the positioning grooves 6 on the two adjacent columns 2 to complete the installation of the side plate 3. The operation is repeated to complete the installation of the remaining three side plates 3. Then, the eight positioning strips 7 are limited by four limiting pieces, and the positioning strips 7 cannot be removed from the positioning grooves 6. The base plate 1, the four columns 2, and the four side plates 3 are assembled to form a cavity. When processing larger concrete components, a layer of release agent is brushed into the cavity, and concrete is poured into the cavity. The surface is smoothed, and air bubbles in the concrete are expelled by vibration. After a certain period of time, demolding can proceed. During demolding, the positioning strip 7 is released by the limiting device, allowing the side plate 3 to move upwards away from the two adjacent columns 2. The positioning strip 7 exits the positioning groove 6. Then, the positioning block 5 is released by the locking device, allowing the column 2 to move upwards away from the base plate 1. The positioning block 5 exits the through hole 4, thus disassembling the application into multiple relatively independent units, namely the base plate 1, four columns 2, four side plates 3, and adjusting plate 8, to facilitate demolding. Conversely, in addition to adding... When working with smaller concrete components, the adjusting plate 8 is positioned vertically within the cavity, dividing the cavity into two forming chambers. The size of the two forming chambers can be adjusted by moving the adjusting plate 8 horizontally. The adjusting plate 8 is then locked in place by the locking mechanism. A layer of release agent is brushed into the forming chamber, and concrete is poured into the forming chamber and smoothed. Air bubbles in the concrete are expelled by vibration. After a certain period of time, demolding can be performed. During demolding, the adjusting plate 8 is unlocked by the locking mechanism, and the demolding operation described above is repeated.

[0029] In summary, this application is easy to install and disassemble, which helps to reduce the space occupied during storage, facilitates demolding, and is adjustable. It does not require changing different molds when processing concrete components of different specifications, making it convenient to use and therefore more practical.
