[0022] After punching is completed, the pusher plate 5 will be driven by the first spring 11 to push the first slide rod 10 to squeeze the clutch hub, so as to slide the clutch hub out of the moving mold 3 and demold the clutch hub.

[0023] like Figures 1 to 4As shown, the bottom end of the moving mold 3 is provided with a storage groove 12 for storing the push plate 5.

[0024] The storage slot 12 can store the push plate 5, which is placed in the clutch hub to prevent it from being squeezed and damaged during the punching process.

[0025] like Figures 1 to 4 As shown, a mold base 13 is fixedly installed at the bottom of the punching frame 1, and guide rods 14 are symmetrically fixedly installed at the top of the mold base 13. The half mold 7 is slidably installed between the two guide rods 14. Triangular blocks 15 are symmetrically fixedly installed on the outer side of the moving mold 3. An inclined surface 16 is opened on the outer ring of the middle part of the half mold 7. The inclined surface 16 is in contact with the triangular block 15. A return spring 17 is sleeved on the outer side of both ends of the guide rod 14. One end of the return spring 17 is fixedly connected to the half mold 7, and the other end of the return spring 17 is fixedly connected to the mold base 13.

[0026] The hydraulic rod 2 drives the moving mold 3 to descend, and the triangular abutment 15 on the moving mold 3 will press the inclined surface 16 on the half mold 7 to control the two half molds 7 to move closer to each other along the trajectory of the guide rod 14, and to control the two half molds 7 to be assembled into the fixed mold 6. At this time, the return spring 17 is in a compressed state. After punching is completed, the hydraulic rod 2 drives the moving mold 3 to rise, and the triangular abutment 15 on the moving mold 3 will rise to gradually press the upper part of the inclined surface 16. The return spring 17 pulls the two half molds 7 to move the two half molds 7 away from each other, and to reset the half molds 7.

[0027] like Figures 1 to 4 As shown, a second storage hole 18 is provided inside the bottom end of the half mold 7. The push rod 8 is slidably installed inside the second storage hole 18. A second spring 19 is fixedly installed at the bottom end of the push rod 8. The bottom end of the second spring 19 is fixedly connected to the bottom end of the half mold 7 corresponding to the second storage hole 18.

[0028] The hydraulic rod 2 drives the moving mold 3 to rise, and the second spring 19 pushes the push rod 8 to push the push rod 8 upward to squeeze the clutch hub, so as to slide the clutch hub out of the fixed mold 6.

[0029] like Figures 1 to 4 As shown, the bottom end of the punching frame 1 is provided with an inclined guide groove 20 corresponding to the middle position of the mold base 13.

[0031] This utility model provides a punching device for automotive parts, the specific working principle of which is as follows:

[0032] When the device is in use, the clutch hub is placed between the two half molds 7. At this time, the push rod 8 is pushed by the second spring 19, which will cause the push rod 8 to squeeze the clutch hub. At this time, the clutch hub cannot be completely placed inside the fixed mold 6. At the same time, the push plate 5 is pushed by the first spring 11, which will cause the push plate 5 to protrude from the bottom end of the moving mold 3. Then, the moving mold 3 is driven down by the hydraulic rod 2, and the push plate 5 will squeeze the clutch hub. The squeeze of the clutch hub will cause the first slide rod 10 connected to the push plate 5 to slide and be stored inside the first storage hole 9. At this time, the first spring 11 is in a compressed state. Subsequently, the moving mold 3 will squeeze the clutch hub. At the same time, the triangular stop block 15 on the moving mold 3 will press the inclined surface 16 on the half mold 7 to control the two half molds 7 to move closer to each other along the trajectory of the guide rod 14, and to control the two half molds 7 to be assembled into the fixed mold 6. At this time, the return spring 17 is in a compressed state. Meanwhile, the clutch hub will be completely housed inside the fixed mold 6 due to the pressure of the moving mold 3. The clutch hub will also push the push rod 8 to slide and house inside the second housing hole 18. At this time, the second spring 19 is in a compressed state. During this process, the punching rod 4 on the moving mold 3 will press the clutch hub for punching the clutch hub.

[0033] After punching is completed, the moving mold 3 is raised by the hydraulic rod 2. The push rod 8 is pushed by the second spring 19, which pushes the push rod 8 upward to squeeze the clutch hub, so as to slide the clutch hub out of the fixed mold 6. At the same time, the push plate 5 is squeezed by the first slide rod 10 pushed by the first spring 11, so as to slide the clutch hub out of the moving mold 3 for demolding of the clutch hub, preventing the clutch hub from getting stuck on the outside of the moving mold 3 and inside the fixed mold 6, and facilitating the demolding of the clutch hub. At the same time, the triangular block 15 on the moving mold 3 will rise to gradually squeeze the top of the inclined surface 16. The two half molds 7 will be pulled away from each other by the return spring 17, so as to reset the half molds 7.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
