[0026] Specifically, Figure 1 and Figure 2 As shown, after the stamped back panel is placed on the top of the lower die 4, the hydraulic cylinder 7 is then started to drive the top seat 6 and the upper punching die 5 to move downward. At the same time, during the downward movement, the four groups of pressure plates 9 on both sides will first contact the back panel at the top of the lower die 4. During the continued downward movement of the top seat 6, the limit plate 17 will be used to compress the compression spring 16 inside the inner groove 15 upward, so that the pressure plate 9 can be tightly against the back panel at the top of the lower die 4. The four groups of pressure plates 9 can be set up to assist in positioning and fixing the back panel when the upper punching die 5 moves downward to punch and trim the back panel inside the lower die 4, thereby reducing and avoiding the displacement of the back panel during punching.

[0027] Embodiment 2: A handle 13 is fixedly mounted on the front end of the movable platform 3, and sliders 10 are respectively fixedly mounted on the rear ends of both sides of the bottom of the movable platform 3, and slide grooves 11 are respectively opened inside the two sides of the top of the bottom platform 2, and locking blocks 12 are respectively set on both sides of the top of the front end of the bottom platform 2, and the bottom of the front end of the locking block 12 is provided with a hexagon socket bolt 19, and threaded holes 20 are respectively opened inside the two sides of the front end of the bottom platform 2;

[0028] Specifically, Figure 1 and Figure 3 As shown, when unloading, the locking blocks 12 set on both sides of the top of the front end of the base 2 can be rotated outward by ninety degrees, and the movable platform 3 can be unlocked by moving the movable platform 3 forward and backward on the top of the base 2. Then, the movable platform 3 can be pulled forward by pulling the handle 13 using the slider 10, and at the same time, the lower mold 4 can be driven to move out of the bottom end of the upper punching and cutting mold 5, and the back panel parts inside the lower mold 4 can be taken out from the outside for unloading. At the same time, the next group of back panel parts to be punched and trimmed can be placed on the lower mold 4 for loading. By moving the top position of the lower mold 4 out, the situation where the space between the lower mold 4 and the upper punching and cutting mold 5 is narrow and inconvenient for loading and unloading can be reduced, and safety accidents caused by accidental startup of the upper punching and cutting mold 5 during loading and unloading can be prevented.

[0029] Embodiment 3: Insert blocks 14 are welded and fixed on both sides of the top of the upper punching die 5 and both sides of the bottom of the lower die 4, and a through hole 23 is opened inside the insert block 14, slots 18 are opened on both sides of the bottom of the top seat 6 and both sides of the top of the movable table 3, and insert rods 21 are respectively arranged on both sides of the front end of the top seat 6 and the movable table 3, and the insert rod 21 passes through the interior of the front end of the movable table 3, a screw hole 22 is opened at the rear end of the slot 18, the through hole 23 passes through the interior of the insert block 14, the rear end of the insert rod 21 passes through the interior of the through hole 23, and an external thread is opened at the rear end of the outside of the insert rod 21;

[0030] Specifically, Figure 1 , Figure 3 and Figure 4 As shown, the provided insertion rod 21 can be rotated in the opposite direction on both sides of the front end of the top seat 6 and the movable table 3 to make the rear end withdraw from the inside of the screw hole 22, and then the insertion rod 21 can be pulled forward from the through hole 23 inside the insertion block 14, and then the lower mold 4 and the upper punching mold 5 can be unlocked and disassembled at the top end of the movable table 3 and the bottom end of the top seat 6, respectively. After that, the upper punching mold 5 and the lower mold 4 of different models and sizes can be replaced and reinstalled, and the back panels of different sizes and specifications can be trimmed.

[0031] Working principle: when the utility model is in use, after the back plate of the punching is placed on the top of the lower die 4, the hydraulic cylinder 7 is then started to drive the top seat 6 and the upper punching and cutting die 5 to move downward. At the same time, during the downward movement, the four groups of pressure plates 9 on both sides will first contact the back plate at the top of the lower die 4. During the continuous downward movement of the top seat 6, the limit plate 17 will be used to compress the compression spring 16 inside the inner groove 15 upward, so that the pressure plate 9 can be tightly against the back plate at the top of the lower die 4. The four groups of pressure plates 9 can be used to assist in positioning and fixing the back plate when the upper punching and cutting die 5 moves down and punches and trims the back plate inside the lower die 4, thereby reducing and avoiding the displacement of the back plate. After the back plate is punched and trimmed inside the top of the lower die 4, when unloading, the locking blocks 12 can be rotated outward by ninety degrees on both sides of the top of the front end of the bottom platform 2, and the movable platform 3 can be unlocked after the front and rear displacement of the movable platform 3 at the top of the bottom platform 2. Then, the movable platform 3 can be pulled forward by the slider 10 by pulling the handle 13. After the lower die 4 is driven to move out of the bottom end of the upper punching and cutting die 5, the back plate parts inside the lower die 4 can be taken out and unloaded from the outside, and at the same time, the next group of back plate parts to be punched and trimmed can be placed on the lower die 4 for loading. By moving the top position of the lower die 4 out, on the one hand, the situation that the space between the lower die 4 and the upper punching and cutting die 5 is small and inconvenient for loading and unloading can be reduced, and on the other hand, the safety accidents caused by accidental startup of the upper punching and cutting die 5 during loading and unloading can be prevented. When the trimming die is in use, the provided insertion rod 21 can be rotated in the opposite direction on both sides of the top seat 6 and the front end of the movable table 3 respectively to make the rear end withdraw from the inside of the screw hole 22, and then the insertion rod 21 is pulled out forward from the through hole 23 inside the insert block 14 respectively, and the lower die 4 and the upper punching and cutting die 5 can be unlocked and disassembled at the top end of the movable table 3 and the bottom end of the top seat 6 respectively. After that, the upper punching and cutting die 5 and the lower die 4 of different models and sizes are replaced and reinstalled, and back plates of different sizes and specifications can be trimmed.
