Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Reference Figure 1 and Figure 3 The utility model provides an embodiment of a stamping die for automobile metal parts, comprising a base 1, the top of the base 1 being fixedly connected to a protective box 7, the inner wall of the protective box 7 being slidably connected to a lower die 6, the inner wall of the lower die 6 being slidably connected to two connecting rods 5, the bottom of the connecting rod 5 being fixedly connected to a rack 8, the inner wall of the lower die 6 being fixedly connected to a plurality of support rods 11, the top of the support rod 11 being rotatably connected to a connecting rotating rod 10, one end of the connecting rotating rod 10 being fixedly connected to a driven gear 9, the other end of the connecting rotating rod 10 being fixedly connected to a first bevel gear 12, one side of the rack 8 being meshed with the outside of the driven gear 9, the inner wall of the lower die 6 being rotatably connected to two screws 14, the outside of the screw 14 being fixedly connected to a second bevel gear 13, the top of the screw 14 being threadedly connected to a moving block 15, a buffer assembly being installed inside the protective box 7, the buffer assembly being used to cushion the impact force exerted on the lower die 6 when the die is closed. One side of the first bevel gear 12 is meshed with the bottom of the second bevel gear 13. Two limiting grooves 21 are defined on the top of the lower die 6 , and the outer portion of the moving block 15 is slidably connected to the inner wall of the limiting groove 21 .

[0023] Specifically, when the hydraulic cylinder 3 drives the upper mold 4 to move upward, the upper mold 4 plays a fixing role on the connecting rod 5, thereby driving the connecting rod 5 to rise synchronously, and the connecting rod 5 plays a fixing role on the rack 8, thereby driving the rack 8 to move synchronously, so that under the interaction between the rack 8 and the driven gear 9, the driven gear 9 is driven to rotate, and the driven gear 9 plays a fixing role on the connecting rotating rod 10, thereby driving the connecting rotating rod 10 to rotate synchronously, so that the support rod 11 plays a limiting role on the connecting rotating rod 10, so that the connecting rotating rod 10 The rotation is more stable, so that the first bevel gear 12 can rotate stably, and then under the action of the first bevel gear 12 and the second bevel gear 13, the second bevel gear 13 is driven to rotate, so that the screw 14 rotates synchronously, and the limiting groove 21 has a limiting effect on the moving block 15, so that the moving block 15 rises along the inner wall of the limiting groove 21, so that when the upper mold 4 is stamped and raised, the mold on the top of the lower mold 6 is simultaneously ejected by the moving block 15, so that the stamped automobile parts can be conveniently taken out.

[0024] Reference Figure 1 and Figure 2 The buffer assembly includes a slide rod 16, the ends of which are fixedly connected to the inner wall of the protective box 7. Two movable sliders 17 are slidably connected to the outside of the slide rod 16. Springs 18 are sleeved on the outer ends of the slide rod 16. The top of the movable slider 17 is rotatably connected to a connecting rod 19, and one end of the connecting rod 19 is rotatably connected to a fixed block 20. One end of the spring 18 is fixedly connected to the inner wall of the protective box 7, and the other end of the spring 18 is fixedly connected to the outside of the movable slider 17. The top of the fixed block 20 is fixedly connected to the bottom of the lower mold 6.

[0025] Specifically, when the mold is closed, the upper mold 4 produces an impact on the lower mold 6, so that the lower mold 6 exerts downward pressure on the fixed block 20, driving the rotation of the two connecting rotating rods 19, and the slide bar 16 limits the two movable sliders 17, pushing the two movable sliders 17 to move along the outside of the slide bar 16, and the movable slider 17 fixes one end of the spring 18, thereby compressing the spring 18, so that under the action of the spring 18, the impact force on the lower mold 6 can be alleviated, thereby better protecting the internal structure of the lower mold 6.

[0026] Reference Figure 1 The top of the base 1 is fixedly connected to the top plate 2, the top of the top plate 2 is fixedly connected to the hydraulic cylinder 3, and the output end of the hydraulic cylinder 3 is fixedly connected to the upper mold 4. The top of the connecting rod 5 is fixedly connected to both ends of the upper mold 4.

[0027] Specifically, the base 1 fixes the top plate 2 and the top plate 2 fixes the hydraulic cylinder 3. By starting the hydraulic cylinder 3, the upper mold 4 can be stably driven to move up and down, so that the upper mold 4 can stamp the automotive parts inside the lower mold 6. The upper mold 4 fixes the connecting rod 5, thereby synchronously driving the connecting rod 5 to move up and down.

[0028] Working principle: When using this device, the automobile metal parts to be punched are placed on the top of the lower die 6. By starting the hydraulic cylinder 3, the upper die 4 can be driven to move up and down, so that the upper die 4 can punch the automobile parts inside the lower die 6, and simultaneously drive the connecting rod 5 to move up and down. In the process of punching the automobile parts, the lower die 6 is moved along the inner wall of the protective box 7, thereby exerting downward pressure on the fixed block 20, driving one end of the two connecting rotating rods 19 to move. Under the action of the other end of the connecting rotating rod 19, the two moving sliders 17 are pushed to move along the outside of the slide rod 16, thereby compressing the spring 18. Under the action of the spring 18, the impact force on the lower die 6 can be alleviated, thereby better protecting the internal structure of the lower die 6.

[0029] When the stamping is completed, the upper mold 4 rises, driving the connecting rod 5 to rise synchronously, thereby driving the rack 8 to move synchronously. Under the interaction of the rack 8 and the driven gear 9, the driven gear 9 is driven to rotate, thereby driving the connecting rotating rod 10 to rotate synchronously. Under the action of the support rod 11, the connecting rotating rod 10 is more stable when rotating, thereby making the first bevel gear 12 rotate stably, and then under the action of the first bevel gear 12 and the second bevel gear 13, the second bevel gear 13 is driven to rotate, so that the screw 14 rotates synchronously, so that the moving block 15 at the top of the screw 14 rises along the inner wall of the limit groove 21. In this way, when the upper mold 4 is stamped and rises, the mold on the top of the lower mold 6 is synchronously ejected by the moving block 15, so that the stamped automobile parts can be conveniently taken out.

[0030] 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.
