A limit opening 12 is formed on the first right-angle plate 11, and one side of the limit opening 12 is an inclined surface. A first fixed block 13 is fixedly connected to the center of the left and right end faces of the mold 5. A slider 1 is slidably connected to the inner side of the first sliding groove 7. 4. An electric push rod 15 is fixedly connected to the upper inner side of the first slide groove 7, and the output end of the electric push rod 15 is fixedly connected to the slider 14. A second fixing block 16 is fixedly connected to the front end of the slider 14, and the first fixing block 13 and the second fixing block 16 are fixedly connected to each other. A slide groove opening 17 is opened on the front end of the second fixing block 16. A connecting column 18 is rotatably connected to the second fixing block 16, and the right end of the connecting column 18 is rotatably inserted into the first fixing block 13 and fixedly connected to the mold 5. The connecting column 18 is a telescopic column. A first gear 19 is fixedly connected to the left end of the connecting column 18, and the first gear 19 is located inside the second slide groove 8. A limit block 20 is fixedly connected to the center of the rear end face of the first gear 19.

[0022] A second right-angle plate 21 is slidably connected to the slid groove 17. The second right-angle plate 21 has a C-shaped frame plate 22 fixedly connected to its left end face, and the C-shaped frame plate 22 is located on the left end face of the second fixed block 16. Simultaneously, a first gear 19 is located inside the C-shaped frame plate 22. A second toothed groove 23 is provided on the rotating contact surface of the first fixed block 13 with the mold 5. A second gear 24 is rotatably connected to the inner side of the mold 5, and the second gear 24 meshes with the second toothed groove 23. A first bevel gear 25 is fixedly connected to the center of the lower end face of the second gear 24 via a connecting column. The upper end of the mold 5 has multiple mold openings 26 on both ends.

When the mold 5 moves to the work station, the positioning pin springs into the groove to achieve precise positioning.

[0023] The working principle of this embodiment is as follows: First, when the stamping press 2 contacts the mold 5 through the stamping die, it pushes the mold 5 downward. The connecting column 18 drives the first fixing block 13 to slide the second fixing block 16 inside the straight slide groove 401. In turn, the slider 14 slides inside the first slide groove 7. When the second fixing block 16 moves to the inside of the bottom first right angle plate 11, the second right angle plate 21 is engaged inside the limit port 12.

At the same time, the limit block 20 is inserted into the inside of the third slide groove 10. After completion, the stamping press 2 is controlled to disengage from the mold 5. At this time, the electric push rod 15 is turned on to drive the slider 14 to move upward. In turn, the second fixing block 16 drives the first gear 19 to move upward. Secondly, when the first gear 19 moves, it will contact and mesh with the first tooth groove 9. The first gear 19 rotates, and the connecting column 18 drives the mold 5 to rotate and flip over, so that the next stamping can be carried out quickly without waiting. Third, when the mold 5 rotates, it drives the second gear 24 to move through the second tooth groove 23, causing the second gear 24 to rotate itself. This drives the first bevel gear 25, the second bevel gear 28, and the connecting rod 29 to rotate. At the same time, the protrusion 30 lifts the T-shaped plate 27, which in turn pushes the nut out from the inside of the mold opening 26 and onto the upper surface of the triangular plate 6 for collection, without the need for manual operation.

[0024] This utility model provides an improved progressive multi-station mold for high-speed stamping of nuts. In use, the limiting port 12 drives the second right-angle plate 21 to move left and right, which in turn drives the first gear 19 to move and cooperate with the first tooth groove 9. This causes the mold 5 to move upward and rotate automatically, thus achieving immediate stamping. At the same time, the second tooth groove 23 drives the second gear 24 to rotate, which in turn drives the connecting rod 29 to drive the protrusion 30 to lift the T-shaped plate 27, thus achieving automatic removal of the nut.
