A second rotating plate 4 is fixedly mounted on one end of the rotating rod 9, and a first threaded rod 5 is fixedly mounted on the other end of the rotating rod 9. The outer ring of the first threaded rod 5 is threadedly connected to a lower die 13. The lower die 13 is slidably mounted inside the sliding groove 7. The mounting cover 1 is located on the upper end of the base 3. A second internal thread groove 24 is opened on both sides inside the mounting cover 1. A second threaded rod 23 is threadedly connected inside the second internal thread groove 24. A first rotating plate 2 is fixedly mounted on one end of the second threaded rod 23. A locking block 11 is rotatably mounted on the end of the second threaded rod 23 away from the first rotating plate 2. An upper die 12 is locked and mounted on the two locking blocks 11 with their close surfaces engaged. The upper die 12 is locked and mounted inside the mounting cover 1 through the locking blocks 11.

[0026] refer to Figure 4 The lower mold 13 has an integrally formed sliding plate 16 at one end of the sliding groove 7. The lower mold 13 is slidably installed inside the upper end of the base 3 via the sliding plate 16. Limiting grooves 6 are opened on both sides of the sliding groove 7. Limiting plates 18 are integrally formed on both sides of the sliding plate 16. The limiting plates 18 are slidably installed inside the limiting grooves 6. The sliding of the limiting plates 18 inside the limiting grooves 6 can effectively achieve the stability of the lower mold 13 when it moves.

[0027] refer to Figure 2 The sliding plate 16 has a first internal threaded groove 17 at its center. The upper end of the base 3 has a rotating opening 8 on the side away from the sliding groove 7. The rotating rod 9 is rotatably installed in the inner ring of the rotating opening 8. The first threaded rod 5 is threadedly connected to the lower mold 13 through the first internal threaded groove 17 in the sliding plate 16. When the first threaded rod 5 rotates, the lower mold 13 will move in a straight line along the sliding groove 7 under the action of the sliding plate 16, so as to realize the functions of dismantling and loading.

[0028] refer to Figures 4 to 6 The upper mold 12 has a stop post 15 fixedly installed on both sides of the upper end. The upper mold 12 and the lower mold 13 have a stop groove 21 opened inside both sides of the upper mold 12. The stop post 15 is slidably installed inside the stop groove 21 to prevent the upper mold 12 and the lower mold 13 from closing, which would lead to poor stamping quality.

[0029] refer to Figures 5 to 6The mounting cover 1 has a mounting groove 10 inside one end near the base 3. The upper mold 12 is engaged and installed inside the mounting cover 1 through the mounting groove 10. Retention grooves 22 are provided on both sides of the mounting groove 10. Springs 19 are fixedly installed inside each retention groove 22. The ends of the two springs 19 away from the retention grooves 22 are fixedly installed on one end of the engaging block 11. Engaging grooves 14 are provided on both sides of the upper mold 12. Engaging blocks 11 are engaged and installed inside the engagement grooves 14. Bearings 20 are fixedly installed on the ends of the two engagement blocks 11 away from the engagement grooves 14. The second threaded rod 23 is away from the first rotating... One end of the moving plate 2 is fixedly installed on the inner ring of the bearing 20. Both springs 19 are sleeved on the outer ring of the second threaded rod 23. Rotating the first rotating plate 2 causes the second threaded rod 23 to rotate in the second internal thread groove 24. Since the second threaded rod 23 is connected to the locking block 11 through the bearing 20, the rotation of the second threaded rod 23 will cause the locking block 11 to move horizontally. Under the action of the spring 19, the locking block 11 gradually approaches the upper mold 12 and is locked into the locking grooves 14 on both sides of the upper mold 12, thereby achieving a firm installation of the upper mold 12. The function of the spring 19 is to provide buffering and pre-tightening force.

[0030] Operating principle and advantages: Before use, rotating the second rotating plate 4 will cause the rotating rod 9 to rotate. Since the rotating rod 9 is fixedly connected to the first threaded rod 5, the first threaded rod 5 will also rotate. The first threaded rod 5 and the lower mold 13 are threadedly connected through the first internal thread groove 17 inside the sliding plate 16. According to the thread transmission principle, when the first threaded rod 5 rotates, the lower mold 13 will move linearly along the sliding groove 7 under the action of the sliding plate 16. The limiting grooves 6 on both sides of the sliding groove 7 and the limiting plates 18 on both sides of the sliding plate 16 cooperate with each other to ensure the stability and accuracy of the lower mold 13 during the sliding process, prevent it from deviating, and ensure the accuracy of the stamping position. Place the upper mold 12 into the placement groove 10 inside the mounting cover 1, and rotate the first rotating plate 2 to make the second threaded rod 23 rotate in the second internal thread groove 24. Since the second threaded rod 23 is connected to the locking block 11 through the bearing 20, the second threaded rod 23... Rotation causes the locking block 11 to move horizontally. Under the action of the spring 19, the locking block 11 gradually approaches the upper mold 12 and engages in the locking grooves 14 on both sides of the upper mold 12, thus achieving a firm installation of the upper mold 12. The function of the spring 19 is to provide buffering and pre-tightening force to ensure a tight fit between the locking block 11 and the locking groove 14. At the same time, the abutment 15 at the upper end of the upper mold 12 and the abutment groove 21 at one end of the lower mold 13 cooperate with each other to play a positioning and guiding role in the stamping process, further improving the stamping accuracy. After the upper and lower molds 13 are installed and adjusted, the material to be stamped is placed on the lower mold 13. Pressure is applied by external stamping equipment to make the upper mold 12 move downward and cooperate with the lower mold 13 to complete the stamping of the car handle shell. During the stamping process, the abutment 15 slides in the abutment groove 21 to ensure accurate alignment of the upper and lower molds 13 and ensure that the stamped car handle shell meets the design requirements.
