[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] This utility model provides a pipe pile mold closing device for pipe pile production, including a base plate 1. A mold base 2 is fixedly installed on the upper surface of the base plate 1 by support feet. A lower mold 3 is slidably installed inside the mold base 2. A gantry frame is provided on the upper surface of the base plate 1. A mold closing assembly 4 is provided on the surface of the gantry frame. The mold closing assembly 4 includes a sliding block 401 slidably connected to the inner top wall of the gantry frame. A first electric push rod 402 is fixedly installed on the lower surface of the sliding block 401. A connecting plate 403 is fixedly installed on the lower surface of the first electric push rod 402. Mounting rods are fixedly installed on both sides of the lower surface of the connecting plate 403. One end of the mounting rod is connected to a connecting seat 404 through an insert rod. An upper mold 5 is fixedly installed on the lower surface of the two connecting seats 404. Connecting blocks 405 are fixedly installed on both sides of the upper mold 5 and the lower mold 3. Limiting grooves are formed on both sides of the mold base 2. The lower connecting block 405 is slidably connected to the inside of the limiting groove. All are fixedly installed with a fixed base 406. The side surface of the upper connecting block 405 is provided with a limiting groove 407. The side surface of the fixed base 406 is provided with a first sliding groove. The inside of the first sliding groove is slidably connected to an arc block 408. The arc block 408 slides and matches the limiting groove 407. One end of the arc block 408 is fixedly installed with a first spring 409. One end of the first spring 409 is fixedly installed with a locking post. The locking post slides through and is connected to the surface of the fixed base 406. One end of the two locking posts is fixedly installed with a pull plate 410. The inside of the pull plate 410 is threadedly connected with a threaded rod 411. One end of the threaded rod 411 is rotatably connected to a support plate. The support plate is fixedly installed on the upper surface of the mold base 2. The upper surface of the sliding block 401 is fixedly installed with a vertical plate. The surface of the gantry is provided with a first sliding groove. The vertical plate is slidably connected to the inside of the first sliding groove. The upper surface of the gantry is fixedly installed with a second electric push rod 14. One end of the second electric push rod 14 is fixedly installed with a vertical plate.
[0026] The operator connects the upper mold 5 to the connecting plate 403 and the connecting seat 404 via a plug rod, and then connects it to one end of the plug rod with a nut to ensure the stability of the connection between the connecting plate 403 and the connecting seat 404. Next, the first electric push rod 402 is activated to lift the upper mold 5, raising it to a height higher than the lower mold 3. Then, the second electric push rod 14 is activated to drive the sliding block 401 to slide, causing the upper mold 5 below the sliding block 401 to slide directly above the lower mold 3. Finally, the first electric push rod 402 is activated again to move the upper mold 5 downwards, causing the upper mold 5 and the lower mold 3 to engage. This reduces the workload of staff, improves their work efficiency and the practicality of the device. During the downward sliding of the upper mold 5, the connecting blocks 405 on both sides of the upper mold 5 press the arc blocks 408 on both sides, causing the arc blocks 408 on both sides to contract inward and press the first spring 409 inside. When the upper mold 5 is completely closed with the lower mold 3, the restoring force of the first spring 409 drives the arc blocks 408 to be inserted into the limiting grooves 407 on the side surface of the connecting blocks 405, thereby limiting the position of the upper mold 5, ensuring the stability of the connection between the upper and lower molds, and improving the yield of the pipe pile mold closing device.
[0027] When it is necessary to release the limit on the upper mold 5, the pull plate 410 is moved by rotating the threaded rod 411. The pull plate 410 moves the locking pins at both ends. The locking pins move the first spring and the arc block 408 at one end, so that the arc block 408 is disengaged from the limiting groove 407, thereby releasing the limit operation on the upper mold 5.
[0028] The lower surface of the connecting block 405 has a locking hole, and a top post 6 is slidably connected inside the locking hole. The top post 6 is slidably connected through the mold base 2. A lifting frame 7 is fixedly installed at the bottom of several top posts 6. A lead screw 8 is threadedly connected inside the lifting frame 7. A drive motor 9 is provided on the lower surface of the mold base 2. A lead screw 8 is fixedly installed at the output end of the drive motor 9.
[0029] When it is necessary to limit the lower mold 3, slide the lower mold 3 inside the mold base 2 to the designated position, and then start the drive motor 9 to drive the lead screw 8 to rotate. The rotation of the lead screw 8 drives the lifting frame 7 to slide upward, and the lifting frame 7 drives the top column 6 to slide upward, so that the top column 6 is inserted into the locking hole on the lower surface of the connecting block 405, thereby limiting the connecting block 405 and the lower mold 3 and fixing the position of the lower mold 3.
[0030] The inner sidewall of the mold base 2 is provided with several auxiliary wheels 10. One end of each of the several bottom auxiliary wheels 10 is fixedly mounted with a rotating column. Gears are fixedly mounted on the outer surface of each rotating column. A toothed chain belt 11 is meshed with the outer surface of several gears. A first motor 12 is fixedly mounted on the side surface of the mold base 2. A rotating column is fixedly mounted on the output end of the first motor 12.
[0031] The worker places the lower mold 3 inside the mold base 2, and then starts the first motor 12 to drive the rotating column to rotate. The rotating column drives the gears on the outer surface to rotate. The gears move through the toothed chain belt 11, causing other gears to rotate, which in turn causes the bottom auxiliary wheels 10 to rotate. The rotating auxiliary wheels 10 move the lower mold 3, thereby transporting the lower mold 3 to the designated position, reducing the workload of the workers and improving work efficiency.
[0032] A rubber pad is provided on the upper surface of the base plate 1, and an upper mold support seat 13 is provided on the surface of the rubber pad.
[0033] In the initial state, the upper mold 5 is placed on the surface of the upper mold support 13, and the rubber pad at the bottom provides a shock absorption effect.
[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
