[0024] Embodiment, please refer to Figures 1-4 , the present utility model provides a technical solution:

[0025] A stamping device for a door aluminum hinge, comprising a bottom plate 1. A top plate 7 is fixedly connected to the top of the bottom plate 1. A first mold 16 is abutted against the surface of the top plate 7. A through hole 17 is formed in the first mold 16. A driving motor 3 is installed at the bottom of the bottom plate 1. The output end of the driving motor 3 is fixedly connected to a threaded cylinder 4. A threaded rod 5 is threadedly connected in the threaded cylinder 4. The top of the threaded rod 5 is fixedly connected to a pushing rod 6. The pushing rod 6 is opposite to the position of the through hole 17. A sliding groove 13 is formed in the top plate 7. A moving plate 14 is slidably connected in the sliding groove 13. The top of the moving plate 14 is fixedly connected to a pressing plate 15. The pressing plate 15 is arranged on the side of the first mold 16. The pressing plate 15 abuts against the first mold 16. An electric telescopic rod 10 is installed at the top of the bottom plate 1.

[0026] In this embodiment, as Figure 1 and Figure 2 shown, a side plate 11 is fixedly connected to the side of the electric telescopic rod 10. A push rod 12 is arranged between the side plate 11 and the moving plate 14. The two ends of the push rod 12 are respectively hinged to the side plate 11 and the moving plate 14. A cylinder 20 is installed at the top of the top plate 7. The bottom of the cylinder 20 is fixedly connected to a sliding plate 18. The bottom of the sliding plate 18 is fixedly connected to a second mold 19. The second mold 19 and the first mold 16 are opposite in position. A noise reduction box 8 is slidably connected to the top of the top plate 7. A glass plate 9 is fixedly connected to the outer surface of the noise reduction box 8. A plurality of equally spaced flannelette balls 21 are fixedly connected to the inner wall of the noise reduction box 8.

[0027] Among them, after the stamping of the door aluminum hinge is completed, the driving motor 3 can be driven to drive the threaded cylinder 4 to rotate, and the pushing rod 6 can be driven to move upward through the threaded rod 5. The door aluminum hinge can be pushed upward through the pushing rod 6, so as to facilitate the separation of the door aluminum hinge from the mold, and improve the practicability and convenience of the stamping device during use.

[0028] In this embodiment, as Figure 3 and Figure 4 shown, a support rod 2 is fixedly connected to the bottom of the bottom plate 1. Anti-slip patterns are formed at the bottom of the support rod 2. The shape of the support rod 2 is T-shaped. The material of the push rod 12 is stainless steel. The push rod 12 is obliquely arranged between the side plate 11 and the moving plate 14. The shape of the glass plate 9 is rectangular. The glass plate 9 is arranged on the sides of the first mold 16 and the second mold 19. The material of the pressing plate 15 is stainless steel. The pressing plate 15 is arranged on both sides of the first mold 16. Anti-slip patterns are formed on the surface of the pressing plate 15.

[0029] Among them, the side plate 11 can be driven to move through the electric telescopic rod 10, and the moving plate 14 can be driven to move through the push rod 12, so that the pressing plate 15 abuts against the first mold 16, and thus the first mold 16 can be fixed to avoid accidental movement during stamping. At the same time, the noise generated during stamping can be reduced through the noise reduction box 8 and the flannelette balls 21, and the quietness of the stamping device during use can be improved.

[0030] Working process of the utility model: When the stamping device of the door aluminum hinge designed by this solution is working, turn on the switch of the electric telescopic rod 10. Drive the side plate 11 to move through the electric telescopic rod 10, and drive the moving plate 14 to slide in the chute 13 through the push rod 12, so that the moving plate 14 drives the extrusion plate 15 to move. The first mold 16 can be abutted and limited through the extrusion plate 15. Then, place the aluminum plate on the surface of the first mold 16, and slide the noise reduction box 8 to the center of the top of the top plate 7. When the cylinder 20 works, drive the slide plate 18 and the second mold 19 to move downward. Through the abutting action between the first mold 16 and the second mold 19, the door aluminum hinge can be stamped and formed. Moreover, the noise reduction box 8 and the flannel ball 21 can improve the quietness of the entire stamping device during use. When the door aluminum hinge is formed, drive the motor 3 to drive the threaded cylinder 4 to rotate. Since the threaded cylinder 4 is threadedly connected to the threaded rod 5, the threaded rod 5 and the abutting rod 6 can be driven to move upward. The door aluminum hinge is ejected from the first mold 16 through the abutting rod 6, improving the convenience of the stamping device during use.
