[0035] Reference Figure 1 and Figure 5A fixed component is provided on the inner middle side of the workbench 26, and the fixed component is used to fix the lower mold 2. The fixed component includes a motor 21, which is used to provide driving force. It is mainly a Y series three-phase asynchronous motor, specifically Y132M-4. The motor 21 is fixedly connected to the inner middle side of the workbench 26. A rotating rod 22 is fixedly connected to the top of the motor 21. The left and right ends of the rotating rod 22 are both rotatably connected to the driving rod 23. The motor 21 is used to control the rotation of the rotating rod 22, and the two driving rods 23 connected to the rotating rod 22 can drive the driving rod 23 to rotate when the rotating rod 22 rotates. The two driving rods 23 are far apart. One end is rotatably connected to a connecting rod 24, and the two connecting rods 24 are respectively slidably connected to the left and right sides of the middle part of the workbench 26. The tops of the two connecting rods 24 are fixedly connected with a splint 25. The connecting rod 24 is used to connect the splint 25 and the driving rod 23. When the driving rod 23 rotates, the connecting rod 24 slides in the middle part of the workbench 26 and does not rotate accordingly, thereby driving the splint 25 to move horizontally. The two splints 25 are respectively slidably connected to the left and right sides of the lower mold 2 on the opposite side, and the bottoms of the two splints 25 are respectively slidably connected to the left and right sides of the top of the workbench 26. The splint 25 is used to fix the lower mold 2.

[0036] Reference Figure 1 and Figure 4 The two limiting plates 19 are fixedly connected to the opposite sides thereof with a plurality of evenly distributed compression springs 20 , and the opposite sides of the plurality of compression springs 20 are fixedly connected to the inside of the brush plate 17 .

[0037] Working principle: When in use, the lower mold 2 is placed in the middle position of the top of the workbench 26, and then the motor 21 is started. The motor 21 controls the rotation of the rotating rod 22. When the rotating rod 22 rotates, it drives the driving rod 23 to rotate around one end of the rotating rod 22 as the axis, and the connecting rod 24 at the other end of the driving rod 23 slides in the middle of the workbench 26, so that when the driving rod 23 rotates, the clamping plate 25 can only move horizontally left and right. When the two clamping plates 25 move toward each other and contact the left and right sides of the lower mold 2, the motor 21 can be turned off, and the metal powder can be poured between the upper mold 1 and the lower mold 2. Then, the upper mold 1 and the lower mold 2 are fitted together for stamping.

[0038] After the processing is completed, the electric push rod 12 is started, so that the electric push rod 12 drives the moving block 14 to move forward. When the moving block 14 moves, the brush plate 17 is driven to move together. When the brush plate 17 moves, the brushes 18 on the upper and lower sides of the brush plate 17 move along the bottom of the upper mold 1 and the top of the lower mold 2 respectively, thereby collecting and cleaning the excess metal powder. When the brush 18 moves to the front side of the workbench 26, the lifting rod 15 descends to sweep the metal powder into the collecting hopper 3, thereby collecting the powder.

[0039] Finally, after the powder in the collecting hopper 3 is collected to a certain extent, the two shifting blocks 5 are pushed upward, so that the shifting blocks 5 stretch the tension spring 7 and drive the card block 9 to move. After the card block 9 moves upward until it slides out of the card slot 10 opened in the mounting block 11, the collecting hopper 3 can be taken out through the handle 4. When installing the collecting hopper 3, the shifting block 5 is moved upward accordingly, so that the shifting block 5 stretches the tension spring 7. After the collecting hopper 3 drives the two mounting blocks 11 into the workbench 26, the shifting block 5 can be released, and the shifting block 5 is driven to move by the resetting of the tension spring 7, so that the card block 9 slides into the card slot 10, forming a limit for the mounting block 11, and fixing the collecting hopper 3 in the workbench 26.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
