The surface of the adjusting block 13 is covered with flexible rubber 14 with a hardness of Shore A 30-40 degrees. In the material pushing process, the flexible rubber 14 contacts the surface of the stamping die to avoid the rigid contact between the material pushing plate 9 and the stamping die, so as to protect the surface of the stamping die from being scratched.

[0079] Subsequently, the auxiliary material pushing assembly starts to work, and the top of the lower die holder 2 is symmetrically connected with a connecting plate 18. The back of the latter group of connecting plates 18 is connected with a servo motor 19.

[0080] The servo motor 19 is started, and the output end thereof is connected with a rotating shaft 20. The servo motor 19 drives the rotating shaft 20 to rotate. The rotating shaft 20 is sleeved with a conveying roller 21, and the rotating movement of the rotating shaft 20 is transmitted to the conveying roller 21, so that the conveying roller 21 starts to rotate.

[0082] One side of the lower die seat 2 is connected with a discharge chute 22, the stamping die is finally fed into the discharge chute 22 under the conveying of the conveying roller 21, the inner side wall of the discharge chute 22 is provided with a tungsten carbide wear-resistant coating with a thickness of 0.5-1 mm, which can resist the friction generated when the stamping die slides in the discharge chute 22, and the inclination angle of the discharge chute 22 is 30°-45°, so that the stamping die can smoothly slide down along the discharge chute 22 under the action of gravity.

5. A stamping die with a discharge structure according to claim 1, characterized in that: The top of the lower die holder (2) is connected to an auxiliary discharge assembly, which is used to continue to convey the stamping die after it is pushed out. The auxiliary discharge assembly includes a connecting plate (18) symmetrically connected to the top of the lower mold base (2). A servo motor (19) is connected to the back of the rear set of connecting plates (18). The output end of the servo motor (19) is connected to a rotating shaft (20). A conveying roller (21) is sleeved on the outer surface of the rotating shaft (20).

6. A stamping die with a discharge structure according to claim 5, characterized in that: The outer surface of the conveying roller (21) is provided with an anti-slip rubber layer, and a spiral guide groove is provided on the surface of the anti-slip rubber layer. The depth of the guide groove is 3-5mm. The guide groove is used to guide the stamping part to move on the conveying roller (21) and prevent it from deviating during the rolling process.

7. A stamping die with a discharge structure according to claim 1, characterized in that: The lower mold base (2) is connected to a discharge chute (22) on one side; The inner wall of the discharge chute (22) is provided with a wear-resistant coating, which is a tungsten carbide coating with a thickness of 0.5-1mm; The inclination angle of the discharge chute (22) is 30°-45°.

8. A stamping die with a discharge structure according to claim 1, characterized in that: The top of the lower mold base (2) is connected to a guide post (23), and a guide sleeve (24) is sleeved on the outer surface of the guide post (23), and the guide sleeve (24) is embedded inside the upper mold base (1); The other end of the guide post (23) is connected to the top wall of the stamping die protective body (7).

9. A stamping die with a discharge structure according to claim 1, characterized in that: The top of the stamping die protective body (7) is embedded with a hydraulic rod three (25), and the output end of the hydraulic rod three (25) is connected to the top of the upper die base (1).

10. A stamping die with a discharge structure according to claim 1, characterized in that: The stamping die protective body (7) is integrally formed of steel. The interior of the stamping die protective body (7) is provided with reinforcing ribs, which are used to enhance the structural strength of the stamping die protective body (7).
