Description

Technical Field

[0001] This invention relates to the field of concrete impermeability test block technology, and in particular to a rapid demolding and molding device for concrete impermeability test blocks. Background Technology

[0002] A concrete impermeability test block is mainly used to detect the water penetration in concrete. By measuring the amount of water penetration and the time on the tested area of ​​the test block, the waterproof performance of the concrete can be determined. The test block is widely used in concrete impermeability testing in highway engineering construction testing, railway engineering construction testing, building site engineering construction testing, commercial concrete mixing plant testing, building engineering quality supervision testing, as well as various colleges, universities, research institutions, water conservancy projects and other fields.

[0003] To this end, patent CN205138975U discloses an automatic molding and demolding device for concrete impermeability test blocks. The device includes a molding and demolding operating platform equipped with a hydraulic press. The operating platform has a movable cover plate and an automatic lifting platform. When raised, the automatic lifting platform is flush with the operating platform surface; when lowered, it is flush with a lower conveyor roller conveyor. One side of the lower conveyor roller conveyor is equipped with an automatic push rod capable of automatically pushing concrete test blocks or molds onto it. Both sides of the molding and demolding operating platform are equipped with upper conveyor roller conveyors capable of conveying concrete test blocks or molds. The ends of the upper conveyor roller conveyors are equipped with hydraulic lifting trolleys. This invention allows for molding and demolding of concrete test blocks simply by pushing them along the conveyor roller conveyor, eliminating the need for frequent manual lifting and lowering of concrete test blocks and molds. The operation is automated, labor-saving, and highly efficient in molding and demolding.

[0004] The above-mentioned technology only requires pushing the concrete test block or mold along the conveyor roller to complete the molding or demolding of the concrete test block during molding and demolding. It does not require frequent manual lifting and placing of the concrete test block and mold. However, when closing the mold of the concrete test block, the mold is prone to displacement, which causes the upper mold and lower mold to shift and fail to close. Therefore, a rapid demolding and molding device for concrete impermeable test blocks is needed to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a rapid demolding and molding device for concrete impermeable test blocks, which solves the problem that existing rapid demolding and molding devices are inconvenient to clamp the lower mold when molding concrete impermeable test blocks, resulting in the mold easily shifting position when the concrete test block is closed, causing the upper and lower molds to fail to close.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a rapid demolding and molding device for concrete impermeable test blocks, comprising a workbench and a reaction frame fixed at its top, an oil pump assembly installed on one side of the top of the workbench, an oil cylinder fixed at the top of the reaction frame, a lower mold placed at the bottom of the reaction frame, an upper mold installed at the bottom of one end of the oil cylinder, clamping structures provided on both sides of the upper mold, a demolding structure provided at one end of the workbench, and a pushing structure provided at the other end of the workbench;

A fixing block is welded to one side of the connecting plate. A through groove is opened inside one side of the fixing block. A through groove is opened on one side of the through groove. A guide groove is opened inside the other side of the through groove.

[0008] An extrusion block is installed inside the guide groove. A ramp is provided on one side of the extrusion block. The fixing plate is fixed at the middle position of both sides of the lower mold. A gear plate is installed on one side of the fixing plate. A rotating disk is fixed to one side of the fixing plate at one end of the gear plate. A fixing column is fixed to one side of the rotating disk. A connecting frame is sleeved on the outside of the fixing column. A moving column is hinged to one side of the connecting frame. The guide sleeve is fixed to both sides of the lower mold.

[0009] Preferably, springs are fixed at both ends on one side of the extrusion block, and one end of the spring is fixed to one side of the through groove, forming a telescopic structure between the extrusion block and the spring.

[0010] Preferably, the springs are provided in two sets, and the two sets of springs are symmetrically distributed on one side of the compression block.

[0011] Preferably, the surface of the rack is provided with teeth, and the rack meshes with the gear disc.

[0012] Preferably, the movable column is inserted into the interior of the guide sleeve, and a sliding connection is formed between the movable column and the guide sleeve.

[0013] Preferably, the extrusion blocks are provided in two sets, and the two sets of extrusion blocks are symmetrically distributed on both sides of the lower mold.

[0014] Preferably, the pushing structure includes a guide rail, a mounting plate, a second cylinder, and a push plate. The guide rail is fixed to both sides of the top of the worktable, the mounting plate is fixed to one side of the top of the worktable, the second cylinder is fixed to one side of the guide rail, and a push plate is installed at one end of the second cylinder.

[0015] Preferably, the guide rails are provided in two sets, and the two sets of guide rails are symmetrically distributed on both sides of the top of the worktable.

[0016] Preferably, the demolding structure includes a flipping plate, a base, a barrier block, a mounting base, a first cylinder, a clamping plate, a connecting base, and a connecting block.

[0019] 1. With the clamping structure, the hydraulic cylinder can easily place the upper mold on top of the lower mold when closing the upper and lower molds, eliminating the need for manual operation and making it more convenient to install concrete. When closing the mold, the fixed frame will squeeze the extrusion block to clamp the lower mold, preventing the lower mold from moving during mold closing, thus completing the clamping work. As the fixed frame continues to move downward, the cooperation between the fixed frame and the toothed disc will drive the moving column to move inside the guide sleeve and hit the outside of the lower mold, resulting in better concrete test block production.

[0020] 2. By setting up a demolding structure, the lower mold is clamped by the cooperation between the clamping plate and the blocking block. After clamping, the first cylinder retracts to tilt the flipping plate downward, thereby allowing the concrete test block inside the lower mold to fall out, making demolding more convenient.

[0033] Example 1:

[0034] Please see Figures 1-10The present invention provides a rapid demolding and molding device for concrete impermeable test blocks, comprising a workbench 1 and a reaction frame 4 fixed at its top.

A lower mold 8 is placed at the bottom of the reaction frame 4. The lower mold 8 is cylindrical inside and has the following dimensions: height 160mm, upper diameter 200mm, bottom diameter 279mm, and wall thickness 15mm. An upper mold 9 is installed at the bottom of one end of the oil cylinder 3. Clamping structures 7 are provided on both sides of the upper mold 9.

[0035] Reference Figures 1-10 As shown: The clamping structure 7 includes a connecting plate 701, a fixing block 702, a fixing frame 703, a rack 704, a through groove 705, a fixing plate 706, a gear disc 707, a spring 708, a pressing block 709, a ramp 7010, a guide groove 7011, a through groove 7012, a rotating disk 7013, a connecting frame 7014, a fixing column 7015, a moving column 7016, and a guide sleeve 7017. The fixing frame 703 is fixed to both sides of the upper mold 9, and 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 formed inside one side of the fixing block 702. A through groove 705 is formed inside one side of the through groove 7012. A guide groove 7011 is formed inside the other side of the through groove 7012. An extrusion block 709 is installed inside the guide groove 7011. A ramp 7010 is formed on one side of the extrusion block 709. The fixing plate 706 is fixed at the middle position on both sides of the lower mold 8. A geared disc 707 is mounted on one side of the fixed plate 706. A rotating disc 7013 is fixed to one side of the fixed plate 706 at one end of the geared disc 707. A fixing post 7015 is fixed to one side of the rotating disc 7013. A connecting frame 7014 is sleeved on the outside of the fixing post 7015. A moving post 7016 is hinged to one side of the connecting frame 7014. A guide sleeve 7017 is fixed to both sides of the lower mold 8. Springs 708 are fixed to both ends of one side of the extrusion block 709. One end of the spring 708 is fixed to one side of the through groove 7012. The extrusion block 709 and the spring 708 form a telescopic structure. Two sets of springs 708 are provided, and the two sets of springs 708 are symmetrically distributed on one side of the extrusion block 709. The surface of the rack 704 is provided with teeth, and the rack 704 meshes with the gear plate 707. The moving column 7016 is inserted into the interior of the guide sleeve 7017, and the moving column 7016 and the guide sleeve 7017 form a sliding connection. Two sets of extrusion blocks 709 are provided, and the two sets of extrusion blocks 709 are symmetrically distributed on both sides of the lower mold 8.

[0036] Specifically, in this embodiment, when making the concrete impermeable test block, the release agent is first applied to the inner wall of the lower mold 8. After the application is completed, concrete is poured into the interior of the lower mold 8. After pouring, the hydraulic cylinder 3 is activated. After activation, the hydraulic cylinder 3 pushes the upper mold 9 downward, thereby covering the top of the lower mold 8 with the upper mold 9. When the upper mold 9 moves downward, it drives the fixing frame 703 to move. When the fixing frame 703 moves downward, it passes through the through groove 7012 inside the fixing block 702. When the fixing block 702 passes through the fixing block 7012... When the mold is inside 2, the bottom end of the fixing block 702 will be squeezed by the ramp 7010 to move the extrusion block 709 to one side inside the guide groove 7011, and drive the spring 708 to stretch, so that one side of the extrusion block 709 abuts against both sides of the lower mold 8. With the two sets of extrusion blocks 709, the fixing frame 703 can clamp the lower mold 8 when it moves downward. When the fixing frame 703 is pulled out, the extrusion block 709 is restored to its original position under the use of the spring 708, and finally the clamping work of the lower mold 8 is completed.

[0037] As the fixed frame 703 continues to move downward, the rack 704 on one side of the fixed frame 703 will come into contact with the gear plate 707. Through the meshing with the gear plate 707, the rotating plate 7013 will be driven to rotate. When the rotating plate 7013 rotates, it will drive the fixed column 7015 to rotate. When the fixed column 7015 rotates, it will drive the moving column 7016 to move inside the guide sleeve 7017 through the connecting frame 7014 and hit the outside of the lower mold 8. This makes the concrete better when it is installed inside the lower mold 8. Furthermore, the upper mold 9 is covered on the top of the lower mold 8 by the hydraulic cylinder 3, making it more convenient to close the upper mold 9 and the lower mold 8 without manual operation, thus improving convenience.

[0038] Reference Figures 1-10As 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 worktable 1, and the mounting plate 602 is fixed to one side of the top of the worktable 1. A second cylinder 603 is fixed to one side of the guide rail 601, and a push plate 604 is installed at one end of the second cylinder 603. Two sets of guide rails 601 are provided, and the two sets of guide rails 601 are symmetrically distributed on both sides of the top of the worktable 1. The demolding structure 5 includes a flipping 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 flipping plate 601... 1. A rotating plate 501 is set at one end of the workbench 1, and one end of the rotating plate 501 is movably connected to one end of the workbench 1. A blocking block 503 is fixed on one side of the top of the rotating plate 501, and a clamping plate 506 is installed on one side of the blocking block 503. A base 502 is installed at the bottom of the rotating plate 501, and a mounting seat 504 is fixed at the top of the base 502. A first cylinder 505 is hinged to the top of the mounting seat 504. A connecting block 508 is installed at the top of the first cylinder 505. A connecting seat 507 is fixed to the bottom of the rotating plate 501. The connecting block 508 is sleeved on the outside of the middle position of the connecting seat 507, and the connecting block 508 and the connecting seat 507 are hinged together.

[0039] Specifically, in this embodiment, after the concrete anti-permeability test block is made, the second cylinder 603 is activated to push the lower mold 8 onto the flipping plate 501 via the push plate 604. When the lower mold 8 moves onto the flipping plate 501, the clamping plate 506 is moved to one side by rotating the rotating rod, so that one side of the lower mold 8 abuts against one side of the blocking block 503, thereby completing the clamping work of the lower mold 8. After clamping is completed, the first cylinder 505 is activated to retract downward. Since one side of the flipping plate 501 is movably connected to one side of the workbench 1, the first cylinder 505 will cause one side of the flipping plate 501 to tilt downward when it retracts downward. When the flipping plate 501 is tilted, the concrete anti-permeability test block inside the lower mold 8 will slide out from the inside of the lower mold 8, completing the demolding work of the lower mold 8, thereby completing the rapid demolding work of the concrete anti-permeability test block.
