During punching, the edge of the plastic part is abutted against the positioning component 5 to position the plastic part, so that the scrap at the edge of the plastic part is within the cutting area below the cutting component 3. When punching the plastic part is required, the lifting component 2 will drive the cutting component 3 to descend, and the cutting component 3 can descend to punch the plastic part and cut off the scrap at the edge of the plastic part. Before cutting, the fixing component 4 abuts against the plastic part in advance, which can play a role in fixing the plastic part and prevent the plastic part from skewing during cutting. The device has a simple structure and is easy to use.

[0029] In one embodiment, specifically, the lifting component 2 includes a guiding column 21 installed on the base 1, the top of the guiding column 21 is installed with a top plate 22, a cylinder 23 is installed on the top plate 22, the output end of the cylinder 23 is installed with a lifting plate 24, the lifting plate 24 is slidably sleeved on the guiding column 21, and a control panel 25 is installed on the base 1;

[0030] When it is necessary to drive the cutting assembly 3 to descend for punching the plastic part, the cylinder 23 on the top plate 22 can be started. The extension of the output end of the cylinder 23 will drive the lifting plate 24 to slide downward on the guiding column 21. The downward sliding of the lifting plate 24 will drive the cutting assembly 3 to descend for punching the plastic part. After the punching is completed, the cylinder 23 can drive the cutting assembly 3 to lift, and the punched plastic part can be taken out. The control panel 25 can control the operation of the cylinder 23.

[0034] When the cutting tool 32 needs to be replaced after long-term use, the sliding rod 36 is pulled outward of the tool mounting seat 31. At this time, the sliding rod 36 will drive the clamping block 34 away from the card slot 33 and no longer engage with the card slot 33. At this time, the fixing spring 35 will also be compressed. Then, the cutting tool 32 is directly removed from the tool mounting seat 31, and a new cutting tool 32 is snapped into the tool mounting seat 31. The fixing spring 35 will drive the sliding rod 36 to move inward of the tool mounting seat 31, and the movement of the sliding rod 36 will drive the clamping block 34 to re-engage with the card slot 33, thus completing the installation of the cutting tool 32. The operation is relatively convenient. During punching, the cutting tool 32 will enter the punching slot 37 to complete the cutting of the waste material.

When it is necessary to drive the cutting assembly 3 to descend to punch the plastic part, the cylinder 23 on the top plate 22 can be started through the control panel 25. The extension of the output end of the cylinder 23 will drive the lifting plate 24 to slide downward on the guide post 21. The downward sliding of the lifting plate 24 will drive the cutting assembly 3 to descend to punch the plastic part. After punching is completed, control the cylinder 23 through the control panel 25 to drive the cutting assembly 3 to lift, and the punched plastic part can be taken out. On the other hand, when punching, the downward movement of the lifting plate 24 will also drive the extrusion block 43 and the soft pad 44 to descend. The soft pad 44 will abut against the plastic part in advance. During cutting, the compression spring 41 will be compressed and shortened, and the extrusion block 43 and the soft pad 44 will abut against the plastic part, which can play a role in fixing the plastic part. Through the setting of the telescopic rod 42, the extrusion block 43 and the soft pad 44 can be prevented from tilting. When the cutting tool 32 needs to be replaced after long-term use, pull the sliding rod 36 outward from the outside of the tool mounting seat 31. At this time, the sliding rod 36 will drive the clamping block 34 away from the clamping groove 33 and no longer engage with the clamping groove 33. At this time, the fixing spring 35 will also be compressed. Then directly remove the cutting tool 32 from the tool mounting seat 31, and then snap the new cutting tool 32 into the tool mounting seat 31. The fixing spring 35 will drive the sliding rod 36 to move inward into the tool mounting seat 31, and the movement of the sliding rod 36 will drive the clamping block 34 to re-engage into the clamping groove 33, and the installation of the cutting tool 32 can be completed.
