Most of the existing die-cutting dies are special-purpose, which is not convenient to disassemble and replace different processing die cutters according to the shape of the workpiece being processed. The universality and versatility are poor, and most of them are only equipped with a single processing die cutter, which is not convenient for batch die-cutting of the workpiece being processed, and the efficiency of workpiece processing is low; 2. When the existing die-cutting mold is provided with multiple processing cutter dies to process the workpiece, it is inconvenient to adjust the number of processing cutter dies and the spacing between the processing cutter dies at the connected positions according to the processing requirements of the workpiece after the processing cutter dies are installed; 3. In the existing die-cutting dies, the workpiece is mostly placed directly on the base during die-cutting. There is a lack of components for clamping different types of workpieces. Moreover, it is easy to deviate during long-term use. The stability of the workpiece during the die-cutting process needs to be improved.

At this time, the middle part of the fixing plate 14 moves out of the connecting groove 9, thereby releasing the limit between the movable sleeve 11 and the connecting plate 8, and then the movable sleeve 11 is pulled forward or backward, and the movable sleeve 11 slides with the connecting plate 8, thereby driving the processing die 16 to slide back and forth at the lower end of the connecting plate 8, so as to adjust the spacing between the processing die 16 and the processing die 16 at adjacent positions on both sides of the front and rear.

The number of movable sleeves 11 can be increased or decreased according to actual processing requirements to adjust the number of processing cutting dies 16, which is convenient for batch processing of workpieces, thereby greatly increasing the processing efficiency of workpieces. After the adjustment is completed, the baffle 17 is sleeved on the outer side of the correction rail 7. When the baffle 17 contacts the stopper 19, the stopper 19 is squeezed, so that the stopper 19 is retracted and extended at the front end of the mounting plate 4. The stopper 19 squeezes the second spring 18, so that the second spring 18 is elastically deformed. When the baffle 17 is completely sleeved on the front end of the mounting plate 4, the second spring 18 restores its elastic deformation, pushing the stopper 19 and the movable rod 20 to slide at the front end of the mounting plate 4, so that the stopper 19 is fitted at the front end of the baffle 17, thereby facilitating the limiting of the baffle 17 and the mounting plate 4.
