[0027] A test mold for cement-based materials, asFigures 1-6 As shown, it includes a base 1, a first end plate 2 and a second end plate 3 slidingly connected to the base 1, the first end plate 2 and the second end plate 3 are arranged parallel to each other, and a plurality of first partitions 4 and second partitions 5 are vertically arranged at equal intervals on the opposite sides of the first end plate 2 and the second end plate 3, and an intermediate partition 6 parallel to the first end plate 2 is inserted between the first partition 4 and the second partition 5. The tops of the first partition 4 and the second partition 5 are detachably connected to a snap mechanism 7 for locking the first partition 4 and the second partition 5. The base 1 is also provided with a first positioning pin 9 for positioning the first end plate 2 and a fastening mechanism 8 for clamping the second end plate 3.

[0028] The latch mechanism 7 includes a first latch hole 71 and a second latch hole 72, respectively, disposed at opposite ends of the tops of the first and second partitions 4 and 5. A fastener 73 is connected to both the first and second latch holes 71 and 72. The fastener 73 secures the first and second partitions 4 and 5 to each other, ensuring the stability of the connections between the components within the test mold and preventing leakage.

[0029] The fastener 73 is a "冂"-shaped structure, including a connecting rod 74 and an insertion rod 75 vertically arranged at both ends of the connecting rod 74. The two insertion rods 75 are respectively inserted into the first clamping hole 71 and the second clamping hole 72. The fastener 73 has a simple structure and is easy to install and disassemble.

[0030] Fasteners 73 come in two sizes: large fastener 731 and small fastener 732. The difference in connecting rod length between large fastener 731 and small fastener 732 is equal to the thickness of intermediate partition 6. The rods of large and small fasteners 731 and 732 are identical in length. By providing two sizes of fasteners 73 to accommodate changes in the distance between first and second partitions 4 and 5, and by combining the detachable connection of intermediate partition 6, the number and size of cavities within the test mold can be adjusted, enabling the preparation of test blocks suitable for various tests, such as compression and flexural strength.

[0031] The fastening mechanism 8 includes a fixing base 81 fixedly connected to the base 1. The fixing base 81 is provided with a through-hole, and a fastening rod 82 is threadedly connected to the hole. One end of the fastening rod 82 is tightly abutted against the outer wall of the second end plate 3, and the other end of the fastening rod 82 is provided with a handle 83. By rotating the handle 83 clockwise, the fastening rod 82 moves toward the first end plate 2, thereby clamping and fixing the second end plate 3 to the first end plate 2 and the components therebetween; by rotating the handle 83 counterclockwise, the fastening rod 82 moves away from the first end plate 2, loosening the clamping of the second end plate 3, and facilitating the removal of the second end plate 3 from the first end plate 2 and the components therebetween.

[0032] The first positioning pin 9 is fixedly connected to the base 1 , and the first positioning pin 9 abuts against the outer side wall of the first end plate 2 . The first positioning pin 9 facilitates positioning of the first end plate 2 .

[0033] A plurality of second positioning pins 10 are fixedly connected to the base 1, and the second positioning pins 10 abut against the outer side walls of the outermost first partition plate 4 and the second partition plate 5, so as to facilitate positioning of the positions of the first partition plate 4 and the second partition plate 5 through the second positioning pins 10.

[0034] A plurality of first grooves 11 and second grooves 12 are respectively arranged at equal intervals on the opposite sides of the first end plate 2 and the second end plate 3. The first partition plate 4 and the second partition plate 5 are respectively inserted into the first grooves 11 and the second grooves 12. The first partition plate 4 and the second partition plate 5 are inserted and connected with the first end plate 2 and the second end plate 3 to facilitate installation and disassembly and demoulding.

[0035] In a specific embodiment, the heights of the first end plate 2 and the second end plate 3 are both set to 40 mm, the distances between adjacent two first partition plates 4 and adjacent two second partition plates 5 are both set to 40 mm, and the distances between the first end plate 2 and the middle partition plate 6 and between the second end plate 3 and the middle partition plate 6 are both set to 80 mm. So that when there is no middle partition plate in the test mold, three test blocks with the size of 40 mm×40 mm×160 mm can be formed for the flexural test of cement mortar, and when the middle partition plate is inserted into the test mold, six test blocks with the size of 40 mm×40 mm×80 mm can be formed for the compressive test of cement-based grouting materials. During the use process, the lengths and heights of the first and second end plates 2 and 3, the first and second partition plates 4 and 5, and the middle partition plate 6 can be adjusted according to the test requirements to be applicable to the production of test blocks of various sizes.

[0036] Specifically, four first partition plates 4 and four second partition plates 5 are respectively provided, and two first positioning pins 9 and two second positioning pins 10 are respectively provided.

[0037] When the utility model is in use, the first end plate 2 is abutted against the first positioning pin 9, the first and second partition plates 4 and 5 are inserted into the outermost first and second grooves 10 and 11 of the first and second end plates 2 and 3 along the direction of the second positioning pin 10, and the remaining first and second partition plates 4 and 5 are sequentially inserted and connected, and the joints of the assembled components are knocked flat with a hammer. The middle partition plate 6 is inserted between the first partition plate 4 and the second partition plate 5. After the first partition plate 4 and the second partition plate 5 are aligned and closed, the large fastener 731 is inserted into the first and second card holes 72 in the same row, so as to lock and fix the middle partition plate 6, the first partition plate 4 and the second partition plate 5, and then the rotating handle 83 is rotated to make the fastening rod 82 tightly abut against the outer side wall of the second end plate 3 for clamping and fixing. At this time, the test mold has six independent cavities formed by enclosing. The mixed slurry is poured into the six cavities, and the slurry is flush with the upper edges of the first and second end plates 2 and 3. After the slurry is formed, the rotating handle 83 is rotated to loosen the clamping of the second end plate 3 by the fastening rod 82. After the components such as the large fastener 731 and the middle partition plate 6 are removed one by one, the test block is taken out, and the components are cleaned and put into the next use.

[0038] When it is necessary to change the size of the test block to be made, align the first partition plate 4 and the second partition plate 5 in each row directly and then close them tightly. Then insert the small fastener 732 into the first clamping hole 71 and the second clamping hole 72 in the same row to lock and fix the first and second partition plates 4 and 5. Then rotate the turning handle 83 to make the fastening rod 82 tightly abut against the outer side wall of the second end plate 3 for clamping and fixing. At this time, the test mold has three independent cavities formed by enclosing. Pour the mixed slurry into the three cavities, and the slurry is flush with the upper edges of the first and second end plates 2 and 3. After the slurry is formed, rotate the turning handle 83 to loosen the clamping of the fastening rod 82 on the second end plate 3. After removing components such as the small fastener 732 and the first partition plate 4 one by one, take out the test block.
