[0018] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0019] according to Figure 1 , 2As shown in Figures 3 and 4, this embodiment proposes a continuous stamping die for automobile sheet metal parts, including a base plate 1, a rotating mechanism is arranged inside the base plate 1, a mounting plate 2 is installed on the top of the base plate 1, a lower die 3 is installed on the top of the mounting plate 2, a discharging mechanism is arranged inside the lower die 3, a mounting frame 4 is installed on one side above the mounting plate 2, a cylinder 5 is installed at the bottom end of the mounting frame 4, and an upper die 6 is installed at the bottom end of the cylinder 5.

[0020] The discharging mechanism includes an installation cavity 7, a transmission rack 8, a push plate 9, a cavity 10, a driving gear 11, a coupling 12, a first servo motor 13 and a limiting structure. The installation cavity 7 is symmetrically installed inside the lower mold 3. A transmission rack 8 is arranged inside the installation cavity 7. The top end of the transmission rack 8 extends to the outside of the installation cavity 7. The top end of the transmission rack 8 is connected to the bottom end of the push plate 9. A cavity 10 is installed above one side of the installation cavity 7. A driving gear 11 is installed inside the cavity 10. One side of the driving gear 11 is meshed with one side of the transmission rack 8. A coupling 12 is installed at the front end of the lower mold 3. One end of the coupling 12 is connected to one end of the driving gear 11. 2 is provided with a first servo motor 13. When in use, the first servo motor 13 is started to drive the driving gear 11 to rotate. Since the driving gear 11 and the transmission rack 8 are meshed with each other, the driving gear 11 is used to drive the transmission rack 8 to move under the limit of the limit rod 14 and the limit sleeve 15, so the push plate 9 is driven to move, and the stamped sheet metal parts are lifted up by the push plate 9 to facilitate unloading, and then the first servo motor 13 is started again to reverse and drive the push plate 9 to return to its original position, so that the sheet metal parts can be loaded, so that the stamped automobile sheet metal parts are more convenient and efficient when unloading, so that the efficiency of the automobile sheet metal parts is higher during stamping, thereby greatly improving the working efficiency of the stamping die when in use.

[0021] The limiting structure includes a limiting rod 14 and a limiting sleeve 15. The limiting rod 14 is installed on one side of the installation cavity 7. The outer wall of the limiting rod 14 is provided with the limiting sleeve 15. One side of the limiting sleeve 15 is connected to one side of the transmission rack 8. The cross-section of the limiting rod 14 is smaller than the cross-section of the limiting sleeve 15. A sliding structure is formed between the limiting rod 14 and the limiting sleeve 15. When in use, the transmission rack 8 can be limited when moving by utilizing the mutual cooperation between the limiting rod 14 and the limiting sleeve 15, so that the transmission rack 8 is more stable when moving.

[0022] Two lower molds 3 are arranged above the mounting plate 2 , and the two lower molds 3 are symmetrically distributed about the central axis of the mounting plate 2 . The design of the two lower molds 3 enables the mold to work continuously.

[0023] The rotating mechanism includes a second servo motor 16, a worm 17, a worm wheel 18 and a guide structure. The second servo motor 16 is installed at the front end of the base plate 1, and the worm 17 is installed inside the base plate 1. The output end of the second servo motor 16 is connected to one end of the worm 17, and a worm wheel 18 is meshed on one side of the worm 17. The top of the worm wheel 18 is connected to the bottom end of the mounting plate 2. When in use, the second servo motor 16 is started to drive the worm 17 to rotate. Since the worm 17 and the worm wheel 18 are meshed with each other, the worm wheel 18 is used to drive the mounting plate 2 and the lower mold 3 to rotate under the limitation of the limiting groove 19 and the limiting block 20, and one is rotated to the bottom of the upper mold 6, and the cylinder 5 is started to drive the upper mold 6 to move downward. The upper mold 6 is used to stamp the sheet metal. At this time, the staff can load the other lower mold 3, and the cycle is carried out so that the mold works continuously, thereby greatly improving the practicality of the stamping mold when in use.

[0024] The guiding structure includes a limit groove 19 and a limit block 20. The limit groove 19 is opened inside the base plate 1. The limit blocks 20 are symmetrically arranged inside the limit groove 19. The top ends of the limit blocks 20 are connected to the bottom ends of the mounting plate 2. When in use, the limit groove 19 and the limit blocks 20 cooperate with each other to guide the mounting plate 2 during rotation, so that the mounting plate 2 is more stable during rotation.

[0025] Working principle: The staff first places the sheet metal to be stamped on the top of the lower die 3, and then starts the second servo motor 16 to drive the worm 17 to rotate. Since the worm 17 and the worm wheel 18 are meshed with each other, the worm wheel 18 is used to drive the mounting plate 2 and the lower die 3 to rotate under the limit of the limit groove 19 and the limit block 20, and rotate one to the bottom of the upper die 6, and then start the cylinder 5 to drive the upper die 6 to move downward, and use the upper die 6 to stamp the sheet metal. At this time, the staff can load the other lower die 3. After the sheet metal is stamped, start the cylinder 5 to drive the upper die 6 to move upward, and then start the second servo motor 16 to drive the lower die 3 to move upward. The movable mounting plate 2 and the lower mold 3 are rotated to move the unstamped sheet metal to the bottom of the upper mold 6 for stamping. At this time, the first servo motor 13 is started to drive the driving gear 11 to rotate. Since the driving gear 11 and the transmission rack 8 are meshed with each other, the driving gear 11 is used to drive the transmission rack 8 to move under the limit of the limit rod 14 and the limit sleeve 15, so the push plate 9 is driven to move, and the push plate 9 is used to lift the stamped sheet metal to facilitate unloading. Then the first servo motor 13 is started again to reverse and drive the push plate 9 to return to its original position, and the sheet metal is loaded. This cycle allows the mold to work continuously.
