[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-4 As shown, a technical solution provided by the present invention:

[0022] A deformable mold for mold steel processing includes a lower die base 1. A lower die 2 is arranged on the top of the lower die base 1. A cavity 3 is opened on the top of the lower die 2. Guide posts 4 are fixedly arranged at the four corners of the top of the lower die base 1. A top plate 5 is fixedly arranged between the tops of the four guide posts 4. A cylinder 6 is installed on the top of the top plate 5. An upper die base 7 is arranged at the telescopic end of the cylinder 6 at the bottom of the top plate 5. Brackets 8 are fixedly arranged at both ends of the bottom of the upper die base 7. An installation plate 9 is directly arranged inside the brackets 8. A stamping head 10 is arranged at the bottom of the installation plate 9. A fixing mechanism is arranged between one side inside the bracket 8 at the bottom of the upper die base 7 and the installation plate 9;

[0023] Through the above solution, the mold steel workpiece to be processed is placed in the cavity 3 of the lower die 2. The upper die base 7 is moved downward along the guide posts 4 by using the cylinder 6, so that the stamping head 10 stamps the mold steel workpiece;

[0024] In this embodiment, preferably, the fixing mechanism includes a control block 11, a clamping groove 12, a clamping frame 13, a connecting plate 14, a connecting rod 15 and a return spring 16. The control block 11 is movably arranged inside one side of the bracket 8 at the bottom of the upper die base 7 through a mounting hole. A clamping groove 12 is opened at one end of the control block 11. A clamping frame 13 is fixedly arranged on one side of the mounting plate 9. One end of the clamping frame 13 is located inside the clamping groove 12. Connecting plates 14 are fixedly arranged at both ends of one side of the control block 11. A connecting rod 15 is fixedly arranged between the connecting plates 14 on one side. One end of the connecting rod 15 passes through the bracket 8 through a mounting hole. A return spring 16 is sleeved on the outer side of one end of the connecting rod 15. The two ends of the return spring 16 are respectively connected to the connecting plate 14 and the bracket 8;

[0025] Through the above solution, the use of the fixing mechanism can automatically fix the stamping head 10 to be assembled, with simple and convenient operation. At the same time, the fixing mechanism can be disassembled only by operating the control block 11, so that the deformable mold has good usability;

[0026] In this embodiment, preferably, the surface of the control block 11 located on one side of the clamping groove 12 is inclined;

[0027] Through the above solution, when the surface of the control block 11 located on one side of the clamping groove 12 is inclined, it will automatically displace when pressed by the clamping frame 13 to ensure the automatic use of the fixing mechanism;

[0028] In this embodiment, preferably, a guiding groove 17 is formed at the bottom of the upper die base 7, and a plugging board 18 is arranged inside the guiding groove 17 at the top of the mounting plate 9;

[0029] Through the above solution, the cooperation of the guiding groove 17 and the plugging board 18 is used to ensure that when the mounting plate 9 is plugged, the clamping frame 13 can press the inclined surface of the control block 11;

[0030] In this embodiment, preferably, threaded rods 19 are movably arranged on both sides of the lower die 2 at the top of the lower die base 1 through rotating shafts, connection blocks 20 are fixedly arranged on both sides of the outside of the lower die 2, connection grooves 21 are formed at one ends of the connection blocks 20 far away from the lower die 2, the top ends of the threaded rods 19 pass through the connection grooves 21, and pressing blocks 22 are movably arranged on the outer sides of the top ends of the threaded rods 19 above the connection blocks 20 through threads;

[0031] Through the above solution, the assembly and replacement of the lower die 2 can be completed by simply screwing the pressing block 22 and rotating the threaded rod 19, replacing the traditional method of fixing with bolts. Therefore, the assembly and use of the lower die 2 can be carried out without using too many disassembly and assembly tools and steps, further ensuring the usability of the deformable mold;

[0032] In this embodiment, preferably, a limiting block 23 is fixedly arranged at the top end of the threaded rod 19;

[0033] Through the above solution, the limiting block 23 is used to prevent the pressing block 22 from being screwed too much and disengaging from the threaded rod 19;

[0034] When a deformable mold for processing die steel in this embodiment is in use, the workpiece of die steel to be processed is placed in the cavity 3 of the lower mold 2. By using the cylinder 6, the upper mold base 7 moves downward along the guide post 4, so that the stamping head 10 performs stamping processing on the die steel workpiece. According to different production requirements, corresponding lower molds 2 and stamping heads 10 need to be used to meet the processing requirements of die steel with different shapes. When it is necessary to replace the stamping head 10, just press one end of the control block 11, and the clamping frame 13 will be located at the opening of the clamping groove 12. Then, directly pull out the mounting plate 9 to remove the stamping head 10 and the mounting plate 9. And when the clamping frame 13 disengages from the clamping groove 12, the control block 11 can be released. When assembling different stamping heads 10, insert the mounting plate 9 on the stamping head 10 between the brackets 8, and it is necessary to align the insertion plate 18 with the guide groove 17. Thus, when the mounting plate 9 is being pushed, it can be ensured that the clamping frame 13 presses against the inclined surface outside the clamping groove 12, so that the control block 11 generates displacement, and the clamping frame 13 can be embedded into the clamping groove 12 under the action of the subsequent return spring 16, thereby completing the assembly work of the stamping head 10. When it is necessary to replace the lower mold 2, just rotate the pressing block 22. Since the pressing block 22 is connected to the threaded rod 19 by threads, the rotation of the pressing block 22 will make it move away from the connecting block 20. Then, by rotating the threaded rod 19, the lower mold 2 can be taken out. When installing the lower mold 2, just complete the placement work, then rotate the threaded rod 19 to make the pressing block 22 located above the connecting block 20, and then rotate the pressing block 22 to make it press against the connecting block 20, and the lower mold 2 can be fixed.
