[0020] Example 1: Reference Figure 1-Figure 4A stamping device for metal casting processing comprises a base 1, a mounting frame 4 is fixedly connected to the outer wall of the top of the base 1, and a stamping mechanism is arranged in the middle of the mounting frame 4, a die 9 is arranged directly below the stamping mechanism, a pair of electric push rods 3 are arranged at both ends of the die 9, and each pair of electric push rods 3 are fixedly connected to the mounting groove 2 at the telescopic end, the inner wall of the mounting groove 2 is rotatably connected to the threaded rod 11, and a rotating motor 13 is arranged on one side of the threaded rod 11, the outer wall of the threaded rod 11 is threadedly slidably connected to the threaded slider 12, and a moving plate 5 is fixedly connected between the outer walls of the opposite sides of the two threaded sliders 12, a plurality of rows of cleaning strips 21 are equidistantly arranged on the outer wall of the bottom of the moving plate 5, and a toggle rod 20 is arranged between two adjacent rows of cleaning strips 21, a plurality of toggle rods 20 are fixedly connected to the mounting plate 19 at both ends, and the outer walls on both sides of the mounting plate 19 are provided with guide rails. Toward mechanism, driving mechanisms are arranged on both sides of the mounting plate 19. When the stamping parts on the die 9 are stamped by the stamping mechanism, the electric push rod 3 moves the mounting slot 2 upward. When the mounting slot 2 moves to a suitable height, the electric push rod 3 stops running, and then the rotating motor 13 rotates the threaded rod 11 in the mounting slot 2, so that the movable plate 5 can be moved through the threaded slider 12. During the movement of the movable plate 5, the surface of the die 9 can be cleaned through the multiple rows of cleaning strips 21 below it to remove the residues remaining when the die 9 is stamped. When the movable plate 5 moves, the driving mechanism can reciprocate the toggle rod 20 in each adjacent row of cleaning strips 21, so that the cleaning strips 21 can swing back and forth. At the same time, the movable plate 5 can move left and right with the cleaning strips 21, thereby greatly improving the cleaning effect on the surface of the die 9.

[0021] As a further solution in the present invention, the stamping mechanism includes a hydraulic rod 7, which is embedded in the middle of the mounting frame 4, and the telescopic end of the hydraulic rod 7 is fixedly connected to a pressing plate 6, and the bottom outer wall of the pressing plate 6 is fixedly connected to a punch 8. The hydraulic rod 7 can move the punch 8 under the pressing plate 6 downward, so that by cooperating with the die 9 on the base 1, the stamped parts can be stamped.

[0022] As a further solution in the present invention, the driving mechanism includes a transmission box 18, which is fixedly connected to the outer wall at the top of the movable plate 5, and the outer wall on one side of the transmission box 18 is rotatably connected to a rotating shaft 15, and the outer wall on one side of the rotating shaft 15 is fixedly connected to a gear 16, and a rack 10 is meshed under the gear 16, and the rack 10 is fixedly connected to the outer wall at the top of the mounting groove 2. When the movable plate 5 moves, the gear 16 on the rotating shaft 15 of the transmission box 18 is meshed with the rack 10 at the top of the mounting groove 2, thereby enabling the rotating shaft 15 to rotate.

[0023] As a further solution in the present invention, a bevel gear 25 is fixedly connected to the outer wall on the other side of the rotating shaft 15, and a rotating shaft 27 is arranged on one side of the bevel gear 25, a bevel gear 26 is fixedly connected to the outer wall in the middle of the rotating shaft 27, and the bevel gear 26 is meshed with the bevel gear 25, and a turntable 22 is fixedly connected to the outer walls at both ends of the rotating shaft 27, and a connecting plate 23 is hinged between the turntable 22 and the mounting plate 19. Because the bevel gear 25 on the rotating shaft 15 is meshed with the bevel gear 26 on the rotating shaft 27, the rotating shaft 27 can rotate with the turntables 22 at both ends thereof, so that the turntable 22 can make the mounting plate 19 move back and forth with multiple toggle rods 20 through the connecting plate 23.

[0024] As a further solution in the present invention, the guiding mechanism includes an inclined plate 17, which is fixedly connected to the outer wall below the movable plate 5, and a slide rod 24 is slidably connected to the lower end of the inclined plate 17, one side of the slide rod 24 is fixedly connected to the outer wall of the mounting plate 19, and the other side of the slide rod 24 is fixedly connected to the limiting plate 14, which can guide the mounting plate 19 and enable it to move on a horizontal plane.

[0025] Working principle: When the stamping part on the die 9 is stamped by the stamping mechanism, the electric push rod 3 moves the installation slot 2 upward. When the installation slot 2 moves to a suitable height, the electric push rod 3 stops running, and then the rotating motor 13 rotates the threaded rod 11 in the installation slot 2, so that the moving plate 5 can move through the threaded slider 12. During the movement of the moving plate 5, the surface of the die 9 can be cleaned through the multiple rows of cleaning strips 21 below it to remove the residue left when the die 9 is stamped. When the moving plate 5 moves, due to the rotating shaft of the transmission box 18 The gear 16 on shaft 15 is meshed with the rack 10 at the top of the mounting groove 2, so that the rotating shaft 15 can be rotated. Because the bevel gear 1 25 on the rotating shaft 15 is meshed with the bevel gear 2 26 on the rotating shaft 27, the rotating shaft 27 can rotate with the turntable 22 at both ends thereof, so that the turntable 22 can make the mounting plate 19 move back and forth with multiple toggle rods 20 through the connecting plate 23. Under the push of the toggle rods 20, the cleaning strip 21 can swing back and forth, and at the same time, the moving plate 5 can move the cleaning strip 21 left and right, thereby greatly improving the cleaning effect on the surface of the die 9.

[0026] Example 2: Reference Figure 1-Figure 7, a stamping device for metal casting processing, compared with Example 1, on the basis of Example 1, a cam 29 is provided on the other side of the threaded rod 11, and an inverted U-shaped frame 34 is provided directly above the cam 29, the top of the inverted U-shaped frame 34 is fixedly connected to the top plate 32, and the inner wall of the inverted U-shaped frame 34 is slidably connected to an arc block 30, and a connecting spring 31 is fixedly connected between the arc block 30 and the top plate 32. When the threaded rod 11 rotates, the cam 29 will rotate synchronously. During the rotation of the cam 29, it will intermittently contact the arc block 30 in the inverted U-shaped frame 34, so that the arc block 30 in the inverted U-shaped frame 34 moves back and forth up and down.

[0027] As a further solution of the present invention, an air bag 33 is arranged between the arc block 30 and the inverted U-shaped frame 34, and an air supply pipe 28 is arranged at the exhaust end of the air bag 33. A gas collecting cavity 35 is arranged inside the movable plate 5, and a plurality of exhaust holes 36 are arranged at equal distances at the bottom of the gas collecting cavity 35. The exhaust holes 36 are all located between the cleaning strips 21, and one end of the air supply pipe 28 is connected to the gas collecting cavity 35. When the arc block 30 moves up and down, the arc block 30 will squeeze the air bag 33, and the gas in the air bag 33 will be discharged. The gas at the squeezed point enters the gas collecting chamber 35 of the movable plate 5 through the gas supply pipe 28, and is then discharged through the multiple exhaust holes 36 below the gas collecting chamber 35. In this process, due to the reciprocating movement of the toggle rod 20, when the gas discharged from the exhaust hole 36 is sprayed on the toggle rod 20, it will be deflected, so that the deflected gas can purge the cleaning strip 21. By cooperating with the toggle rod 20, the cleaning strip 21 can be kept clean without manual cleaning.

[0028] Working principle: when the threaded rod 11 rotates, the cam 29 will rotate synchronously. During the rotation of the cam 29, it will intermittently contact the arc block 30 in the inverted U-shaped frame 34, so that the arc block 30 in the inverted U-shaped frame 34 will move back and forth up and down. When the arc block 30 moves back and forth up and down, the arc block 30 will squeeze the air bag 33, squeeze out the gas in the air bag 33, and the gas at the squeezed place enters the gas collecting chamber 35 of the movable plate 5 through the gas supply pipe 28, and then is discharged through the multiple exhaust holes 36 under the gas collecting chamber 35. In this process, due to the reciprocating movement of the toggle rod 20, when the gas discharged from the exhaust hole 36 is sprayed on the toggle rod 20, it will be deflected, so that the deflected gas can purge the cleaning strip 21. By cooperating with the toggle rod 20, the cleaning strip 21 can be kept clean without manual cleaning.

[0029] Example 3: Reference Figure 1-Figure 8, a stamping device for metal casting processing, compared with embodiment 2, on the basis of embodiment 2, both sides of the top of the pressure plate 6 are slidably connected with sliding rods 38, and the bottom ends of the sliding rods 38 are fixedly connected with pressing plates 37, and connecting springs 40 are fixedly connected between the pressing plate 37 and the pressure plate 6, and the top of the sliding rods 38 is fixedly connected with limiting disks 39.

[0030] Working principle: when the workpiece to be stamped is placed on the die 9 for stamping, when the hydraulic rod 7 moves the punch 8 under the pressure plate 6 downward, the pressing plate 37 under the pressure plate 6 will first contact the workpiece to be stamped on the die 9, and as the pressure plate 6 continues to move downward, the slide bar 2 38 on the pressing plate 37 will slide upward. At this time, the connecting spring 2 40 is compressed, so that under the elastic force generated by the compressed connecting spring 2 40, the pressing plate 37 will apply force to the workpiece to be stamped on the die 9 to clamp and fix it, thereby avoiding the deviation of the stamped workpiece during stamping, which affects the product quality.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
