[0023] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0024] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a clamping device for metal mold production and processing includes a workbench 5 and a fixed block 11. Second thread grooves 21 are formed through the four corners of the upper end of the fixed block 11. The internal threads of the second thread grooves 21 are connected with threaded rods 14. The upper end of the workbench 5 is provided with first thread grooves 20 at positions corresponding to the second thread grooves 21. One end of the threaded rod 14 is connected with the internal threads of the first thread groove 20. A fixed groove 18 is formed through the upper end of the fixed block 11. The fixed block 11 with fixed grooves 18 of different shapes can be disassembled and replaced by rotating and removing the threaded rod 14, so as to adapt to molds of different shapes. The middle part of the upper end of the workbench 5 is formed with a fixed groove 18. There is a sliding groove 19, and the second push plate 16 is slidably connected inside the sliding groove 19. A chip collecting groove 8 is penetrated through the front part of the upper end of the workbench 5. Support rods 2 are fixedly connected at the four corners of the lower end of the workbench 5. The lower end of the support rod 2 is fixedly connected to the bottom plate 1. Two first fixed plates 6 are fixedly connected to the edge of the upper end of the workbench 5. A cylinder 7 is fixedly installed on the inner side of the first fixed plate 6. A clamping plate 15 is fixedly connected to the output end of the cylinder 7. The lower end of the clamping plate 15 is flush with the upper end of the fixed block 11. After the mold is placed in the fixed groove 18, the two clamping plates 15 are driven by the two cylinders 7 to limit the left and right sides of the mold to make the clamping more secure.

[0025] A hydraulic cylinder 17 is fixedly installed in the middle of the upper end of the base plate 1, and the output end of the hydraulic cylinder 17 is fixedly connected to the lower end of the second push plate 16. After the mold processing is completed, the hydraulic cylinder 17 pushes the second push plate 16 to eject the mold from the fixed groove 18, making the mold removal faster.

[0026] A collecting bin 3 is fixedly connected between the workbench 5 and the base plate 1, and a collecting box 4 is slidably connected to the inner side of the collecting bin 3. The upper end of the collecting bin 3 is connected to the chip collecting groove 8. A second fixed plate 9 is fixedly connected to the rear part of the upper end of the workbench 5, and at least one electric push rod 10 is fixedly installed on the inner side of the second fixed plate 9. The output end of the electric push rod 10 is fixedly connected to a first push plate 12. The length of the first push plate 12 is the same as the length of the chip collecting groove 8. The two ends of the first push plate 12 are fixedly connected to a limiting plate 13. The electric push rod 10 pushes the first push plate 12 to push the metal debris on the workbench 5 into the chip collecting groove 8. The debris enters the collecting box 4 through the chip collecting groove 8 and the collecting bin 3 for easy recovery and treatment. The limiting plate 13 is used to prevent metal debris from leaking from both sides of the first push plate 12.

[0027] Working principle: When the device is in use, first select a suitable fixed block 11 according to the metal mold, fix the fixed block 11 to the upper end of the workbench 5 through the threaded rod 14, the first thread groove 20 and the second thread groove 21, then place the metal mold inside the fixed groove 18 and push the clamping plate 15 through the electric push rod 10 to clamp and limit the left and right sides of the metal mold. After the processing is completed, the clamping plate 15 is reset by the electric push rod 10, and then the second push plate 16 is pushed by the hydraulic cylinder 17 to eject the metal mold from the fixed groove 18. When cleaning is required, rotate the threaded rod 14 to disassemble the fixed block 11, and push the first push plate 12 through the electric push rod 10, so as to push the metal debris on the workbench 5 into the chip collecting groove 8. The debris enters the collection box 4 through the chip collecting groove 8 and the collection bin 3, which is convenient for cleaning.
