[0029] The present application will be further described in detail below with reference to the drawings and embodiments.

[0030] Refer to Figures 1 to 4 As shown in the figure, an embodiment of the present application provides a stamping die for automotive metal parts, including a base 1, a lower module 205, and an upper template 4. The lower module 205 is slidably connected to the upper surface of the base 1. A protection mechanism 3 is fixedly connected to the upper surface of the base 1, and a loading and unloading mechanism 2 is fixedly connected to the inner wall of the base 1. The protection mechanism 3 includes a fixed frame 302 fixedly connected to the upper surface of the base 1. A lower pressing plate 303 is fixedly connected to the outer surface of the fixed frame 302. A first baffle 306 and a cooling fan 304 are fixed to the lower surface of the lower pressing plate 303. The loading and unloading mechanism 2 includes a concave block 206 fixedly connected to the inner wall of the base 1. A sliding rod 202 is slidably connected to the outer surface of the concave block 206. The outer surface of the sliding rod 202 is slidably connected to the outer surface of the lower module 205, and a support plate 201 is fixedly connected to the upper end of the sliding rod 202. A through groove 203 is provided on the upper surface of the base 1 to cooperate with the sliding rod 202.

[0031] Refer to Figures 1 to 4, in one aspect of this embodiment, the loading and unloading mechanism 2 further includes a reduction motor 207 fixedly connected to the inner wall of the base 1. The output shaft of the reduction motor 207 is fixedly connected with a threaded rod 204. A sliding block 208 is threadedly connected to the outer surface of the threaded rod 204. The upper surface of the sliding block 208 is fixedly connected to the lower surface of the lower module 205. A heat dissipation grille is embedded in the outer surface of the base 1. A support plate 201 is fixedly connected to the inner wall of the base 1. The other end of the threaded rod 204 is rotatably connected to the outer surface of the support plate 201, and the outer surface of the support plate 201 is in contact with the upper surface of the lower module 205. The upper surface of the fixed frame 302 is fixedly connected with a hydraulic rod 301. The output end of the hydraulic rod 301 passes through the inner side of the fixed frame 302 and is fixedly connected to the upper surface of the lower pressing plate 303. The lower surface of the lower pressing plate 303 is fixedly connected to the upper surface of the upper template 4.

[0032] Referring to Figures 1 to 4 , in one aspect of this embodiment, a through hole 305 is provided on the upper surface of the base 1 corresponding to the outer surface of the cooling fan 304, and a second baffle 307 is fixedly connected to one side of the cooling fan 304 close to the upper template 4.

[0033] Referring to Figures 1 to 4 , in one aspect of this embodiment, multiple groups of heat dissipation holes are provided on the outer surfaces of the first baffle 306 and the second baffle 308.

[0034] Working principle: Place the metal part on the upper surface of the support plate 201, and then start the reduction motor 207. The output shaft of the reduction motor 207 drives the threaded rod 204 to rotate. The rotation of the threaded rod 204 drives the sliding block 208 to slide on the inner wall of the base 1. The sliding of the sliding block 208 drives the lower module 205 to slide on the upper surface of the base 1. The sliding of the lower module 205 drives the sliding rod 202 to slide on the upper surface of the concave block 206. Since the reduction motor 207 is usually integrated by a motor and a reducer, the motor provides the power source, and the reducer reduces the high rotation speed output by the motor to a low rotation speed suitable for the movement control of the sliding block 208 according to different reduction ratios, and at the same time increases the output torque. When the lower module 205 moves below the upper template 4, the sliding rod 202 slides downward, so that the lower surface of the support plate 201 is attached to the upper surface of the lower module 205. Then start the hydraulic rod 301 and the cooling fan 304. The output end of the hydraulic rod 301 drives the lower pressing plate 303 to move downward, so that the lower surface of the first baffle 306 is attached to the upper surface of the base 1, thus facilitating the prevention of the splashing of metal parts. At the same time, the cooling fan 304 and the second baffle 307 slide on the outer surface of the through hole 305. The cooling fan 304 is convenient for dissipating heat from the upper template 4 and the lower module 205, thus facilitating the increase of the service life of the upper template 4 and the lower module 205. When stamping, another set of lower modules 205 can be loaded. After stamping is completed, start the reduction motor 207 to make the lower module 205 move to the other end of the fixed frame 302, so that the sliding rod 202 slides along the outer surface of the concave block 206, which is convenient for separating the stamped metal part from the outer surface of the lower module 205. At the same time, another set of lower modules 205 moves below the fixed frame 302, which is convenient for continuously stamping and forming the metal parts, and to a certain extent increases the stamping efficiency of the metal parts, and at the same time prevents the situation that the hands of the staff are crushed during loading and unloading.
