[0004] In the above solution, the mold is clamped and fixed by a clamping frame, an outer frame, a connecting block, a connecting rod, a toothed plate, a gear, and a pulley. This results in the following disadvantage: the clamping and fixing device cannot clamp and fix molds of different shapes during use, thereby reducing the flexibility and practicality of the device. Utility Model Content

[0005] The purpose of this invention is to provide a clamping and fixing device for mold processing, so as to solve the problem that the clamping and fixing device cannot clamp and fix molds of different shapes when in use, thereby reducing the flexibility and practicality of the device.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a clamping and fixing device for mold processing, comprising two placement plates, the two placement plates being movably disposed above a base, two first support plates being fixed to the top surfaces of the two placement plates, connecting plates being fixed to the outer sides of the two placement plates, and second support plates being fixed to the top surfaces of the two connecting plates, the outer sides of the two second support plates and the two first support plates being provided with a plurality of movable holes, the outer sides of the two second support plates being fixed with a plurality of first hydraulic push rods, the outer sides of the two first support plates being fixed with a plurality of second hydraulic push rods, and one end of each of the telescopic rods of the plurality of first hydraulic push rods and the plurality of second hydraulic push rods passing through a plurality of movable holes and being detachably provided with clamping blocks.

[0007] Preferably, the top surface of the base has a movable groove, and two movable blocks are movably arranged inside the movable groove. The top ends of the two movable blocks are fixedly connected to the bottom surfaces of the two placement plates, and a first threaded hole is opened on one side of each of the two movable blocks. A bidirectional lead screw is rotatably arranged inside the movable groove, and the two first threaded holes are threadedly connected to the threaded ends of the bidirectional lead screw. A rotating hole is opened on the right side of the base, and a drive motor is fixedly arranged on the right side of the base. The output shaft of the drive motor is rotatably arranged in the rotating hole and fixedly connected to the right end of the bidirectional lead screw.

[0008] Preferably, the inner wall of the movable groove is provided with sliding grooves on the front and rear sides respectively, and the two movable blocks are fixed with sliding blocks on the front and rear sides respectively, and the two sliding blocks are slidably arranged in the two sliding grooves respectively.

[0009] Preferably, anti-slip blocks are fixed to the inner sides of several of the clamping blocks, and anti-slip textures are provided on the inner sides of the several anti-slip blocks.

[0010] Preferably, one end of each of the first hydraulic push rods and the telescopic rods of the second hydraulic push rods is fixed with a mounting plate, one side of each of the mounting plates is provided with a second threaded hole, and the outer side of each of the clamping blocks is fixed with a screw, and the threaded end of each of the screws is threadedly connected to the second threaded hole.

[0011] Preferably, the top surfaces of the two placement plates are respectively fixed with anti-slip pads.

[0012] Compared with the prior art, the clamping and fixing device for mold processing that adopts the above technical solution has the following beneficial effects:

[0013] In operation, the operator first places the mold to be processed on the top surface of two placement plates. Then, by activating several first hydraulic push rods, the clamping blocks on these push rods move separately, clamping and fixing the left and right sides of the mold. Subsequently, by activating several second hydraulic push rods, the clamping blocks on these push rods move separately, clamping and fixing the front and rear sides of the mold. Through the coordinated use of the placement plates, first support plate, connecting plate, second support plate, first hydraulic push rods, second hydraulic push rods, and clamping blocks, the clamping blocks achieve multi-directional adjustability and multi-point clamping, facilitating the clamping and fixing of molds of different shapes and improving the flexibility and practicality of the device.

[0014] Second, during use, the drive motor rotates the bidirectional lead screw, which in turn moves the two moving blocks closer or further apart. This allows the distance between the placement plates to be flexibly adjusted according to the size of the mold, improving the flexibility and practicality of the device. The use of the sliding groove and sliding block helps to limit the movement of the moving blocks, preventing them and the placement plates from shifting during movement, thus improving the stability of the placement plates during movement.

[0015] Thirdly, during use, the combination of anti-slip blocks and anti-slip textures increases the friction between the clamping blocks and the mold, ensuring that the mold will not fall off or move during processing and improving the clamping stability. The use of the mounting plate and screw facilitates the disassembly and assembly of the clamping blocks, making maintenance or replacement easier. The anti-slip pads help the mold maintain stability through friction, not only improving the mold's stability during processing but also reducing wear between the mold and the placement plate.

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1-4 As shown, a clamping and fixing device for mold processing includes two placement plates 1, which are movably disposed above a base 2. Two first support plates 3 are fixed to the top surface of the two placement plates 1, and connecting plates 4 are fixed to the outer sides of the two placement plates 1. Second support plates 5 are fixed to the top surface of the two connecting plates 4. Several movable holes 6 are opened on the outer sides of the two second support plates 5 and the two first support plates 3. Several first hydraulic push rods 7 are fixed to the outer sides of the two second support plates 5, and several second hydraulic push rods 8 are fixed to the outer sides of the two first support plates 3. One end of the telescopic rods of the several first hydraulic push rods 7 and the several second hydraulic push rods 8 passes through the several movable holes 6 and is detachably provided with clamping blocks 9.

[0023] In use, the operator first places the mold to be processed on the top surface of the two placement plates 1. Then, by activating several first hydraulic push rods 7, the clamping blocks 9 on the first hydraulic push rods 7 move respectively, clamping and fixing the left and right sides of the mold. Subsequently, by activating several second hydraulic push rods 8, the clamping blocks 9 on the second hydraulic push rods 8 move respectively, clamping and fixing the front and rear sides of the mold. Through the coordinated use of the placement plates 1, the first support plate 3, the connecting plate 4, the second support plate 5, the first hydraulic push rods 7, the second hydraulic push rods 8, and the clamping blocks 9, the clamping blocks 9 achieve multi-directional adjustability and multi-point clamping, which is beneficial for clamping and fixing molds of different shapes, improving the flexibility and practicality of the device.

[0024] like Figures 1-4As shown, the top surface of the base 2 is provided with a movable groove 10. Two movable blocks 11 are movably arranged inside the movable groove 10. The top ends of the two movable blocks 11 are fixedly connected to the bottom surfaces of the two placement plates 1 respectively. A first threaded hole 12 is provided on one side of each of the two movable blocks 11. A bidirectional lead screw 13 is rotatably arranged inside the movable groove 10. The two first threaded holes 12 are threadedly connected to the threaded ends of the bidirectional lead screw 13 respectively. A rotating hole 14 is provided on the right side of the base 2. A drive motor 15 is fixed on the right side of the base 2. The output shaft of the drive motor 15 is rotatably arranged in the rotating hole 14 and fixedly connected to the right end of the bidirectional lead screw 13.

[0025] In use, by starting the drive motor 15, the bidirectional lead screw 13 is rotated, which in turn drives the two moving blocks 11 to move away from or closer to each other. This allows the distance between the placement plates 1 to be flexibly adjusted according to the size of the mold, improving the flexibility and practicality of the device.

[0026] like Figures 1-4 As shown, the inner wall of the movable groove 10 is provided with sliding grooves 16 on the front and rear sides respectively. The front and rear sides of the two movable blocks 11 are respectively fixed with sliding blocks 17. The two sliding blocks 17 are slidably arranged in the two sliding grooves 16. The inner sides of several clamping blocks 9 are respectively fixed with anti-slip blocks 18. The inner sides of several anti-slip blocks 18 are provided with anti-slip textures 19.

[0027] In use, the sliding groove 16 and the sliding block 17 work together to limit the movement of the moving block 11, preventing the moving block 11 and the placement plate 1 from shifting during movement, thereby improving the stability of the placement plate 1 during movement. The anti-slip block 18 and the anti-slip texture 19 work together to increase the friction between the clamping block 9 and the mold, ensuring that the mold will not fall off or move during processing, and improving the clamping firmness.

[0028] like Figures 1-4 As shown, one end of each of the first hydraulic push rods 7 and the second hydraulic push rods 8 is fixed with a mounting plate 20. Each of the mounting plates 20 has a second threaded hole 21 on one side. Each of the clamping blocks 9 has a screw 22 fixed on its outer side. The threaded ends of the screws 22 are threadedly connected to the second threaded holes 21. The top surfaces of the two placement plates 1 are fixed with anti-slip pads 23.

[0029] During use, the mounting plate 20 and screw 22 work together to facilitate the disassembly and assembly of the clamping block 9, making it easier to maintain or replace it. The anti-slip pad 23 helps the mold maintain stability through friction, which not only improves the stability of the mold during processing but also reduces wear between the mold and the placement plate 1.

[0030] 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.
