The fixing frame 703 is fixed to both sides of the upper mold 9. A rack 704 is fixed to one side of the fixing frame 703. The connecting plate 701 is fixed to both sides of the bottom end of the reaction frame 4, a fixing block 702 is welded to one side of the connecting plate 701, a through groove 7012 is provided inside one side of the fixing block 702, a through groove 705 is provided inside one side of the through groove 7012, a guide groove 7011 is provided inside the other side of the through groove 7012, an extrusion block 709 is installed inside the guide groove 7011, a slope 7010 is provided on one side of the extrusion block 709, and the fixing plate 706 is fixed to the middle position of both sides of the lower mold 8, A toothed disc 707 is installed on one side of the fixed plate 706, and a rotating disc 7013 is fixed on one side of the fixed plate 706 at one end of the toothed disc 707. A fixed column 7015 is fixed on one side of the rotating disc 7013. A connecting frame 7014 is sleeved on the outer side of the fixed column 7015. A movable column 7016 is hinged on one side of the connecting frame 7014. A guide sleeve 7017 is fixed on both sides of the lower mold 8. Springs 708 are fixed on both ends of one side of the extrusion block 709. One end of the spring 708 is fixed to one side of the through slot 7012.

The surface of the rack 704 is provided with teeth, and the rack 704 is meshed with the toothed disc 707. The movable column 7016 is inserted into the interior of the guide sleeve 7017, and a sliding connection is formed between the movable column 7016 and the guide sleeve 7017. There are two groups of extrusion blocks 709, and the two groups of extrusion blocks 709 are symmetrically distributed on both sides of the lower mold 8.

[0036] Specifically, in this embodiment, when making the concrete anti-permeability test block, firstly, the release agent is coated on the inner wall of the lower mold 8, and after the coating is completed, the concrete is poured into the lower mold 8. After the pouring is completed, the oil cylinder 3 is started. After the oil cylinder 3 is started, it will push the upper mold 9 to move downward, so that the upper mold 9 covers the top of the lower mold 8. When the upper mold 9 moves downward, it will drive the fixing frame 703 to move. When the fixing frame 703 moves downward, it will pass through the through groove 7012 inside the fixing block 702. When the fixing block 702 passes through the fixing block 70 2, at this time, the bottom end of the fixed block 702 will squeeze the extrusion block 709 to move to one side in the guide groove 7011 through the setting of the slope 7010, and drive the spring 708 to stretch, so that one side of the extrusion block 709 is against the two sides of the lower mold 8. Through the setting of two groups of extrusion blocks 709, the fixed frame 703 can clamp the lower mold 8 when moving downward. When the fixed frame 703 is pulled out, the spring 708 is used to restore the extrusion block 709 to its original position, and finally complete the clamping work of the lower mold 8;

[0037] As the fixed frame 703 continues to move downward, the rack 704 on one side of the fixed frame 703 will contact the toothed disk 707, thereby driving the rotating disk 7013 to rotate through the engagement with the toothed disk 707. When the rotating disk 7013 rotates, it will drive the fixed column 7015 to rotate. When the fixed column 7015 rotates, it will drive the movable column 7016 to move inside the guide sleeve 7017 through the connecting frame 7014 and hit the outside of the lower mold 8, so that the concrete has a better effect when being molded inside the lower mold 8, and the upper mold 9 is covered on the top of the lower mold 8 through the oil cylinder 3, making it more convenient to close the upper mold 9 and the lower mold 8, without manual operation, thereby improving convenience.

[0038] Reference Figure 1-Figure 10As shown: the pushing structure 6 includes a guide rail 601, a mounting plate 602, a second cylinder 603 and a push plate 604. The guide rail 601 is fixed to both sides of the top of the workbench 1, the mounting plate 602 is fixed to one side of the top of the workbench 1, the second cylinder 603 is fixed to one side of the guide rail 601, and the push plate 604 is installed at one end of the second cylinder 603. The guide rail 601 is provided with two groups, and the two groups of guide rails 601 are symmetrically distributed on both sides of the top of the workbench 1. The demoulding structure 5 includes a flip plate 501, a base 502, a blocking block 503, a mounting seat 504, a first cylinder 505, a clamping plate 506, a connecting seat 507 and a connecting block 508. The flip plate 50 1 is arranged at one end of the workbench 1, and one end of one side of the flip plate 501 is movably connected with one end of the workbench 1, a blocking block 503 is fixed on one side of the top of the flip plate 501, a clamping plate 506 is installed on one side of the blocking block 503, a base 502 is installed at the bottom end of the flip plate 501, a mounting seat 504 is fixed on the top of the base 502, a first cylinder 505 is hinged on the top of the mounting seat 504, a connecting block 508 is installed on the top of the first cylinder 505, a connecting seat 507 is fixed to the bottom end of the flip plate 501, the connecting block 508 is sleeved on the outer side of the middle position of the connecting seat 507, and the connecting block 508 and the connecting seat 507 are hinged.

[0039] Specifically, in the present embodiment, when the production of the concrete waterproof test block is completed, the second cylinder 603 is started to push the lower mold 8 onto the flip plate 501 through the push plate 604. When the lower mold 8 moves onto the flip plate 501, the clamping plate 506 is pushed to one side by rotating the rotating rod, so that one side of the lower mold 8 is against one side of the blocking block 503, thereby completing the clamping of the lower mold 8. After the clamping is completed, the first cylinder 505 is started to retract downward. Since one side of the flip plate 501 is movably connected to one side of the workbench 1, the first cylinder 505 will cause one side of the flip plate 501 to tilt downward when it retracts downward. When the flip plate 501 is tilted, the concrete waterproof test block inside the lower mold 8 will slide out from the inside of the lower mold 8, completing the demoulding of the lower mold 8, thereby completing the rapid molding and demoulding of the concrete waterproof test block.
