Technical Field

[0001] The utility model relates to the technical field of clamping devices, in particular to an internal and external mold linkage clamping device for a cement house mold. Background Art

[0002] At present, in the mold closing or mold opening process, it is necessary to clamp or loosen the lower parts of the inner template and the outer template, and then start the mold closing or mold opening. In the prior art, the clamping and reinforcement of the inner template and the outer template in the cement house mold generally use multiple bolts to penetrate the two to achieve clamping. In this way, it is necessary to operate each clamping position separately, which not only has low work efficiency, but also has different clamping degrees between the clamping positions, affecting the construction quality.

[0003] It can be seen that the defects of the current process for clamping the lower ends of the inner and outer templates are as follows:

[0004] The operation is troublesome, not convenient enough, and the fastening of the connection is too low, which easily causes the connection between the two templates to loosen. Content of the Utility Model

[0008] By rotating the bidirectional screw rod, the slider is driven to slide along the fixed rod. The rotating bidirectional screw rod drives two L-shaped plates to approach each other through the movable block, clamping and fixing the bottom template. Then, the inner template and the outer template are respectively placed in contact with the extension plate. By rotating the second handle screw rod, the clamping block is driven to move, clamping the inner template and the outer template respectively between the clamping block and the extension plate. By rotating the first handle screw rod, and the connecting rod is inserted and slides in the fixed plate. The rotating handle screw rod moves the clamping plate through the connecting block, making the clamping plates on both sides approach the L-shaped plates respectively, so that the inner template and the outer template are in contact with the bottom template.

[0009] Preferably, both ends of the bottom of the L-shaped plate are fixed with sliders, and the sliders form an inserted sliding fit with the fixed rod.

[0010] The inserted sliding of the slider along the fixed rod guides and supports the movement of the L-shaped plate.

[0011] Preferably, the middle end of the bottom of the L-shaped plate is fixed with a movable block, and the movable block forms a threaded fit with the bidirectional screw rod.

[0013] Preferably, both ends of the bottom of the clamping plate are fixed with connecting blocks, and one of the connecting blocks is fixedly connected to one end of the connecting rod, and the other connecting block is rotatably connected to one end of the first handle screw rod.

[0014] By rotating the first handle screw rod, the first handle screw rod moves in the fixed plate, and in cooperation with the connecting rod inserted and sliding in the fixed plate, the position of the clamping plate is moved.

[0015] Preferably, the thickness of the extension plate is the same as that of the clamping plate.

[0016] The extension plate with the same thickness is more closely attached after being connected to the clamping plate.

[0017] Preferably, the top of the clamping plate is symmetrically provided with equally spaced insertion holes, and the insertion holes form an inserted fit with the insertion rod.

[0018] By inserting the insertion rod into the insertion hole, the extension plate is connected to the top of the clamping plate.

[0019] Preferably, the top of the connecting plate is provided with an opening, and the opening forms a sliding fit with the clamping block.

[0020] By the clamping block sliding along the opening, when the second handle screw rod rotates, the position of the clamping block can be adjusted.

[0021] The beneficial effects of the present utility model are as follows:

[0022] By rotating the bidirectional screw rod, the two L-shaped plates are driven to approach each other, clamping and fixing the bottom template. Then, the inner template and the outer template are respectively placed in contact with the extension plate.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Embodiment

[0029] Refer to Figures 1-4, a clamping device for the internal and external molds of a cement house mold, including a clamping mechanism 1. At both ends of the top of the clamping mechanism 1, equally spaced extension mechanisms 2 are inserted. The clamping mechanism 1 includes a bottom plate 3, fixing plates 4 fixed on both sides of the top of the bottom plate 3, fixed rods 5 fixed at both ends of the outer walls of the opposite sides of the two fixing plates 4, a bidirectional screw rod 6 rotatably connected between the two fixing plates 4, L-shaped plates 7 connected to both ends of the fixed rods 5 and the bidirectional screw rod 6, clamping plates 10 arranged on the opposite sides of the two L-shaped plates 7, connecting rods 12 inserted and movable with the fixing plates 4, and first handle screws 13 screwed to the fixing plates 4. The extension mechanism 2 includes extension plates 14, insertion rods 15 fixed at both ends of the bottom of the extension plates 14, connecting plates 16 fixed on the top of the extension plates 14, fixed blocks 17 fixed at one end of the top of the connecting plates 16, second handle screws 18 rotatably connected to the fixed blocks 17, and clamping blocks 19 screwed on the rod walls of the second handle screws 18;

[0030] At both ends of the bottom of the L-shaped plate 7, sliders 8 are fixed. The sliders 8 form a plug-in sliding fit with the fixed rods 5. By inserting and sliding the sliders 8 along the fixed rod 6, the movement of the L-shaped plate 7 is guided and supported. At the middle of the bottom of the L-shaped plate 7, a movable block 9 is fixed. The movable block 9 forms a threaded fit with the bidirectional screw rod 6. By the threaded fit between the rotating bidirectional screw rod 6 and the movable block 9, the two L-shaped plates 7 are driven to move relatively. At both ends of the bottom of the clamping plate 10, connecting blocks 11 are fixed. One of the connecting blocks 11 is fixedly connected to one end of the connecting rod 12, and the other connecting block 11 is rotatably connected to one end of the first handle screw 13. By rotating the first handle screw 13, the first handle screw 13 moves in the fixing plate 4, and in cooperation with the connecting rod 12 inserted and sliding in the fixing plate 4, the position of the clamping plate 10 is moved;

[0031] The thickness of the extension plate 14 is the same as that of the clamping plate 10. After the extension plate 14 and the clamping plate 10 with the same thickness are connected, they are more closely attached. Equally spaced insertion holes are symmetrically opened at the top of the clamping plate 10. The insertion holes form a plug-in fit with the insertion rods 15. By inserting the insertion rods 15 into the insertion holes, the extension plate 14 is connected to the top of the clamping plate 10. An opening is opened at the top of the connecting plate 16. The opening forms a sliding fit with the clamping block 19. By sliding the clamping block 19 along the opening, when the second handle screw 19 rotates, the position of the clamping block 19 can be adjusted.

[0032] Working principle:

[0033] During operation, by rotating the bidirectional screw rod 6, the slider 8 slides along the fixed rod 5. The rotating bidirectional screw rod 6 drives the two L-shaped plates 7 to approach each other through the movable block 9, clamping and fixing the bottom template. Then, the inner template and the outer template are respectively placed in contact with the extension plate 14. By rotating the second handle screw rod 18, the clamping block 19 is moved to clamp the inner template and the outer template respectively between the clamping block 19 and the extension plate 14. By rotating the first handle screw rod 13, the connecting rod 12 is inserted and slides in the fixed plate 4. The rotating handle screw rod 13 moves the clamping plate 10 through the connecting block 11, making the clamping plates 10 on both sides approach the L-shaped plates 7 respectively, so that the inner template and the outer template are in contact with the bottom template.

[0034] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
