[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figures 1-6A multi-station automated stamping die for automotive parts includes a support platform 1 and a mounting frame 15. A support rod 2 is rotatably connected to the upper surface of the support platform 1, and a turntable 3 is fixedly connected to the top of the support rod 2. A set of limiting grooves 4 are provided on the upper surface of the turntable 3. A lower die 9 is placed inside each limiting groove 4. The outer surface of the lower die 9 can also be engaged with the limiting groove 4 using a connector. The lower die 9 is set inside the limiting groove 4, which facilitates the subsequent replacement of different limiting grooves 4.

[0027] A set of mating protrusions 5 are fixedly connected to the bottom of the turntable 3. The position of each mating protrusion 5 corresponds to the position of each lower mold 9. The support table 1 has two built-in grooves 6 inside. The inner walls of the two built-in grooves 6 are slidably connected to limit arc surface blocks 7. The two built-in grooves 6 are horizontally slotted, and the two limit arc surface blocks 7 are horizontally arranged blocks. The outer surfaces of the two limit arc surface blocks 7 are in contact with the outer surface of one of the mating protrusions 5 at the same time. When the mating protrusion 5 is between the two limit arc surface blocks 7, the lower mold 9 is vertically aligned with the upper mold 16.

[0028] Springs 8 are fixedly connected to the bottom surfaces of both limiting arc-shaped blocks 7, and the bottom ends of both springs 8 are fixedly connected to the inner bottom wall of the built-in groove 6. The mating protrusions 5 and the outer surfaces of the limiting arc-shaped blocks 7 are as follows: Figure 2 The device is provided with an arc-shaped surface, which allows the mating protrusion 5 to push the limiting arc-shaped block 7, causing the limiting arc-shaped block 7 to retract into the interior groove 6. Under the elastic force of the spring 8, the limiting arc-shaped block 7 can be reset, so as to limit the subsequent mating protrusion 5.

[0029] A set of pushers 10 is fixedly connected to the outer surface of the turntable 3. The pushers 10 help the worker to rotate the turntable 3.

[0030] A support side plate 11 is fixedly connected to the upper surface of the support platform 1, and a top plate 12 is fixedly connected to the top of the support side plate 11. A hydraulic telescopic rod 14 is installed inside the top plate 12. The output end of the hydraulic telescopic rod 14 is fixedly connected to the upper surface of the mounting frame 15. The hydraulic telescopic rod 14 can be supported by the support side plate 11 and the top plate 12, and can be supported to a suitable position.

[0031] Two reinforcing plates 13 are fixedly connected to the outer surface of the supporting side plate 11. The top ends of the two reinforcing plates 13 are fixedly connected to the top plate 12. The reinforcing plates 13 can reinforce the top plate 12, making it easier for the top plate 12 to bear the reaction force of the hydraulic telescopic rod 14.

[0032] The inner wall of the mounting frame 15 is slidably connected to the upper mold 16, and the outer side of the mounting frame 15 is provided with a limiting mechanism 18, which includes a connecting block 1803 and a limiting rod 1804.

[0033] The limiting rod 1804 passes through the mounting frame 15 and extends into the interior of the upper mold 16. The inner wall of the mounting frame 15 has a through groove that matches the limiting rod 1804. The outer surface of the upper mold 16 has an opening that matches the limiting rod 1804. The limiting rod 1804 contacts the openings inside the mounting frame 15 and the upper mold 16, respectively.

[0034] The limiting rod 1804 is fixedly connected to the connecting block 1803. The connecting block 1803 is fixedly connected to the connecting rod 1802. One end of the connecting rod 1802 is fixedly connected to the grip rod 1801. By using the cooperation of the grip rod 1801, the connecting rod 1802 and the connecting block 1803, the limiting rod 1804 can be easily rotated or pulled out.

[0035] A limiting block 17 is fixedly connected to the right side of the mounting frame 15. The outer surface of the connecting block 1803 is in contact with the limiting block 17. The limiting block 17 can limit the connecting block 1803, thereby preventing the upper mold 16 from detaching from the inside of the mounting frame 15.

[0036] Working Principle: When stamping automotive parts, the automotive parts to be stamped are first placed inside each lower die 9. By activating the hydraulic telescopic rod 14, the mounting frame 15 and the upper die 16 can be moved downwards, allowing the automotive parts directly below the upper die 16 to be stamped. Using a set of pushers 10, the turntable 3 can be easily rotated, moving a set of mating protrusions 5. The mating protrusion 5 positioned between two limiting arc surfaces 7 will press down on one of the limiting arc surfaces 7 to disengage from its restraint. The next mating protrusion 5 will then press down on another limiting arc surface 7 and move between the two limiting arc surfaces 7, forming an automatic positioning of the mating protrusion 5. This allows the next lower die 9 carrying the workpiece to move directly below the mounting frame 15 for stamping. During the stamping process, workers can replace stamped automotive parts, avoiding the significant time wasted on removing finished parts and placing new ones, greatly improving the efficiency of stamping automotive parts.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
