[0030] See also Figure 1-Figure 6In order to discharge a small amount of bubbles inside the concrete when it solidifies and hardens, ensure the uniformity of the concrete molding quality, and reduce the error of subsequent detection, two groups of empty slots 16 of reset components are symmetrically opened on the bottom plate 1, and a slide bar 17 is horizontally installed in the empty slot 16. A slider 14 that can slide horizontally on the slide bar 17 is welded at the bottom end of the movable plate 3. A reset spring 18 (located between the side wall of the empty slot 16 and the slider 14) is symmetrically sleeved on the outside of the slide bar 17. The motor 2 of the driving mechanism is fixedly installed on the bottom plate 1 through a mounting seat. The output end of the motor 2 is fixedly connected to a rotating rod 11 through a coupling. The rotating rod 11 A rotating plate 8 is welded to the top, and a connecting piece 12 of a connecting assembly is welded to one side of the top of the rotating plate 8. A connecting column 7 is vertically welded to the middle of one end of the movable plate 3. A rotating block 13 is welded to the side wall of the connecting column 7. The rotating block 13 is rotatably connected to the connecting piece 12 through a connecting rod 9, and a sliding groove 24 matching the connecting piece 12 is provided on the connecting rod 9. It can be rotated by the motor 2, in conjunction with the rotating plate 8, the connecting piece 12 and the connecting rod 9, and at the same time, in conjunction with the expansion and contraction of the reset spring 18, it can conveniently carry the movable plate 3 to make a small reciprocating motion in the horizontal direction, which can assist in the discharge of a small amount of bubbles in the concrete in the mold cavity 6.

[0031] See also Figure 1-Figure 6 In order to facilitate the splicing and demolding of the movable template 4 and the fixed template 5, as well as the subsequent demolding after finalization, the limit blocks 15 of the limit assembly are equidistantly welded at the bottom of the movable template 4, and the movable plate 3 is provided with limit grooves 10 for facilitating the reciprocating sliding of the limit blocks 15.

[0032] In summary, with the aid of the above technical solution of the utility model, when in use, after sampling the concrete to be tested, the concrete is added to the mold cavity 6 respectively, and tested by the pressure sensor 28.

The heating plate 27 works to dry the concrete in the mold cavity 6, and the dried concrete is then dried. After drying and solidification, the pressure sensor 28 is used for detection and the difference is calculated. When shaping is required, the motor 2 stops working, and the concrete in the other mold cavity 6 solidifies naturally. When demoulding is required after shaping is completed, the electric push rod 20 is extended to move the movable template 4, and the limit block 15 slides in the limit groove 10 to ensure stable movement. At the same time, the elastic anti-skid pad 22 on the guide rod 21 leaves the positioning groove 23 and loses its positioning, so that the fixed template 5 and the movable template 4 are separated to achieve demoulding, which can facilitate the testing of the shaped concrete block, and then the electric push rod 20 is reset to bring the movable template 4 close to the fixed template 5, the guide rod 21 is inserted into the through hole, and the elastic anti-skid pad 22 cooperates with the positioning groove 23 to assist in mold closing, which is convenient for next use.
