[0021] The jet chip removal assembly includes a support frame 20 fixedly arranged on one side of the slide 8, a booster air pump 21 is fixedly arranged on the outside of the support frame 20, a booster pipe 11 is arranged at one end of the support frame 20 away from the booster air pump 21, the booster pipe 11 is connected to the booster air pump 21 through a connecting pipe 22 arranged at the air outlet end of the booster air pump 21, two jet pipes 19 are connected and installed at the lower inner side of the booster pipe 11, and two sets of air nozzles 23 are connected and installed at the inner sides of the two jet pipes 19; Reference Manual Attached Figure 1 and Figure 4It can be seen that the booster air pump 21 is set up on the outside of the slide 8 through the support frame 20 for use.

[0023] The telescopic mechanism includes two sets of second hydraulic cylinders 28 fixedly mounted on the outer surface of the shift seat 29. The rear end of the shift seat 29 is provided with a first cylinder 13, which is fixedly arranged inside the cross frame 4. Reference Manual Attached Figure 1 and Figure 2 It can be seen that the first cylinder 13 can adjust the positions of the transfer seat 29 and the bottom plate 30 . During demoulding and positioning of blanking, the first cylinder 13 can be driven to cause the transfer seat 29 to approach the lower die seat 9 .

[0024] The fixed plate assembly includes two groups of connecting frames 31, which are respectively connected to the telescopic ends of the second hydraulic cylinders 28 at the corresponding positions. The ends of the two groups of connecting frames 31 away from each other are fixedly installed with slides 27, and a convex block extends above the slide 27, and a second cylinder 34 is arranged inside the convex block. A slide rod 32 is slidably installed inside the slide 27, and a support rod 25 is fixedly connected inside the end of the slide rod 32 away from the slide 27. The support rod 25 is connected to the telescopic end of the second cylinder 34, and a double-layer clamping rod 26 is arranged at the bottom end of the support rod 25. A side platform 35 is arranged outside the double-layer clamping rod 26. Fixed columns 37 are arranged at both ends of the inner side of the side platform 35 and at the lower position. A support plate 42 is interspersed together at the lower outer sides of the two fixed columns 37. A connecting sleeve is rotatably mounted on the lower outer sides of the two fixed columns 37, and a resisting mold is arranged at the bottom end of the connecting sleeve. Reference Manual Attached Figure 5 and Figure 6 It can be seen that the second hydraulic cylinder 28 can drive the corresponding connecting frame 31 to move up and down, thereby facilitating the unloading of the material sheet in the later stage; Under the telescopic drive of the second cylinder 34, the support rod 25 can drive the double-layer clamping rod 26 to move, and the distance between the double-layer clamping rods 26 can be adjusted to fully meet the use of the sheet. The fixed column 37 can drive the mold member to be used flexibly.

[0025] The mold-resisting member includes multiple groups of arc-shaped rotating blades 41 fixedly installed at the bottom end of the connecting sleeve, the multiple groups of arc-shaped rotating blades 41 are arranged in a circular shape, and a gear 38 is arranged outside the connecting sleeve and above the arc-shaped rotating blades 41. A third cylinder 44 is arranged inside one end of the side platform 35, and a support rod 45 is fixedly arranged at the telescopic end of the third cylinder 44. A rack 39 is fixedly installed at the lower inner side of the support rod 45, and the rack 39 is meshed with the gear 38. The support rod 45 is slidably installed on the inner side of the support plate 42, and a clamping mold assembly is symmetrically arranged in the middle of the inner side of the side platform 35; Reference Manual Attached Figure 6 and Figure 7 It can be seen that the edge of the arc-shaped rotary blade 41 is relatively thin, and can be pressed between the lower mold base 9 and the mold shell. Then, under the telescopic drive of the third cylinder 44, the support rod 45 drives the rack 39 to move back and forth, causing the rack 39 and the gear 38 to rotate, causing the connecting sleeve and multiple groups of arc-shaped rotary blades 41 to rotate, thereby prying at the four corners of the mold shell, moving the mold shell, and facilitating the later demoulding.

[0026] The clamping die assembly includes a slide column 36 that is slidably inserted into the inner side of the side platform 35 and the support plate 42, a spring 33 is sleeved on the outer side of the slide column 36, a stopper 40 is fixedly arranged at the bottom end of the slide column 36, and a plurality of groups of anti-slip seats 43 are arranged on the surface of the stopper 40, and a stopper plate is arranged on the outer side of the slide column 36 and below the spring 33, and the spring 33 is located between the side platform 35 and the support plate 42; Reference Manual Attached Figure 6 and Figure 7 It can be seen that the spring 33 on the outside of the slide post 36 can drive the retaining seat 40 to penetrate into the interior of the mold shell when the arc-shaped rotary vane 41 is operating. When adjusting the position of the arc-shaped rotary vane 41, the elastic expansion and contraction of the spring 33 and the slide post 36 can allow the arc-shaped rotary vane 41 to be close to the mold shell and the lower mold seat 9 without hindering the demolding behavior of the retaining seat 40.

[0027] Working principle: When in use, the driving mechanism can adjust the position of the slide 12 and the lower die seat 9 according to the use of the lower die seat 9. When loading the sheet, the worker can put the cut sheet between the two double-layer clamping rods 26, and the size of the sheet can be controlled by the telescopic drive of the second cylinder 34. The double-layer clamping rod 26 can quickly capture the center of the lower die seat 9 and position the sheet at the lower die seat 9. After putting down the sheet, the first cylinder 13 drives the shift seat 29 and the two second hydraulic cylinders 28 to move to the rear end, and the first hydraulic cylinder 7 can drive the slide 8 and the upper die seat 24 to move downward to stamp the lower die seat 9. The stamped mold is clamped at the lower die seat 9, and the first cylinder 13 moves to the top of the lower die seat 9 again, and then the two sets of abutments 40 are inserted into the two inner parts of the mold. On the side, through the pressure of the anti-slip seat 43, the push seat 40 can stably drive the mold to move away from the inside of the lower mold seat 9. The mold shell that is partially firmly stuck on the edge of the lower mold seat 9 can be driven by the third cylinder 44, so that the support rod 45 and the rack 39 can drive the gear 38 and the connecting sleeve to rotate, so that the arc-shaped rotary blade 41 can be embedded between the mold shell and the lower mold seat 9. During the rotation and pressing process, the arc-shaped rotary blade 41 pries the four sides of the mold shell, thereby prompting the mold shell to separate from the lower mold seat 9, making it convenient for the push seat 40 to move the mold shell more smoothly later. The booster air pump 21 located on both sides of the slide 8 can clean the unused lower mold seats 9 through the connection of the connecting pipe 22 and the booster pipe 11, thereby ensuring the continuous use of each lower mold seat 9.

[0028] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention.
