Description

Technical Field

[0001] This utility model relates to the field of stamping die technology for automotive structural parts, and in particular to a stamping die for automotive structural parts that prevents the upper and lower dies from shifting. Background Technology

[0002] Stamping dies for automotive structural components are essential tools in the production of automotive parts. They shape sheet metal into the desired automotive structural components under high pressure. They play a crucial role in the stamping process, ensuring that the precision, dimensions, and shape of the parts meet requirements, thereby improving production efficiency and product quality. Stamping dies are designed to withstand extreme working conditions such as high pressure and high temperature, while also possessing a long service life, adaptable to the production of various automotive parts.

[0003] Traditional automotive structural component stamping die structures typically include several key components, such as the die body, guide assemblies, pressure plates, and parting lines. These components work together to achieve accurate part forming through precise coordination during the die's operation. Guide assemblies ensure precise die alignment, pressure plates provide sufficient pressure to the metal sheet, and parting lines facilitate product disassembly.

[0004] The tendency for the upper and lower dies to shift in traditional automotive structural component stamping dies is typically related to the die's guiding accuracy and fixing system. Because the upper and lower parts of the die need precise alignment, any gaps or looseness in the guiding system or fixing device can easily lead to displacement of the upper and lower dies, thus affecting the forming accuracy of the parts during stamping. This displacement results in dimensional deviations or poor surface quality of the parts, impacting the final performance and assembly accuracy of the product. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a stamping die for automotive structural parts that prevents the upper and lower dies from shifting. It aims to improve the problem that the upper and lower dies of traditional automotive structural parts stamping dies are prone to displacement, which leads to dimensional deviations or poor surface quality of parts, affecting the final performance and assembly accuracy of the product.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a stamping die for automotive structural parts that prevents displacement of the upper and lower dies, including a bottom die, an upper die provided at the bottom of the bottom die, and connecting members fixedly connected to the side walls of the bottom die and the upper die, with connecting components provided inside the connecting members;

[0035] Reference Figures 1-3This utility model provides an embodiment of a stamping die for automotive structural parts that prevents displacement of the upper and lower dies. It includes a bottom die 1, with an upper die 2 at the bottom of the bottom die 1. Connecting members 3 are fixedly connected to the side walls of both the bottom die 1 and the upper die 2. Connecting components are installed inside the connecting members 3. Each connecting component includes a connecting post 4, which is located inside multiple connecting members 3. A fixing tube 10 is fixedly connected to the lower surface of the connecting post 4. The fixing tube 10 provides support for the sliding fit between the connecting post 4 and the inner shaft 5, ensuring precise movement of the internal components and preventing failure due to excessive friction or resistance during stamping. An inner shaft 5 is slidably connected inside the connecting post 4. A spring 6 is sleeved on the outer wall of the inner shaft 5. The spring 6 provides a certain reaction force to maintain a stable connection between the inner shaft 5 and the push plate 7, ensuring that the push plate 7 can stably advance the push post 8 during stamping. The push plate 7 is fixedly connected to the outer wall of the inner shaft 5. A pusher 8 is fixedly connected to the bottom of plate 7. The pusher 8 is slidably connected inside the fixed tube 10. Multiple limit beads 9 are slidably connected inside the fixed tube 10. The multiple limit beads 9 ensure the stable sliding of the pusher 8 inside the fixed tube 10 and prevent the pusher 8 from shifting. This effectively ensures the fixation and precise docking of the upper and lower dies and avoids inaccurate part dimensions caused by asymmetry or displacement of the upper and lower dies. One end of the spring 6 is fixedly connected to the upper surface of the pusher plate 7, and the other end of the spring 6 is fixedly connected to the inside of the connecting column 4. The elasticity of the spring 6 plays an important role in pushing and buffering during the overall die locking process, ensuring reliable fixation and stability of the stamping die during use. A demolding component is provided on the side wall of the bottom die 1. The design of the demolding component ensures that the die can be smoothly demolded after stamping, reducing the adhesion between the die and the stamped part, and further improving the service life and production efficiency of the die.

[0036] Reference Figure 4 and Figure 5 The demolding assembly includes a cylinder 11 and a fixed base 12. The side wall of the cylinder 11 is fixedly connected to the side wall of the bottom mold 1. The output end of the cylinder 11 is fixedly connected to the fixed base 12. The upper surface of the fixed base 12 is fixedly connected to a fixed platform 13. The fixed platform 13 is rotatably connected to a turntable 14. The side wall of the turntable 14 is fixedly connected to a demolding template 15. The top of the fixed base 12 is fixedly connected to a side plate 16. The side wall of the side plate 16 is rotatably connected to an electric push rod 17. The output end of the electric push rod 17 is fixedly connected to a push table 18. The push table 18 is fixedly connected to a push shaft 19. The side wall of the turntable 14 is fixedly connected to a rotating frame 20. The rotating frame 20 has an inner groove 21. The push shaft 19 is slidably connected inside the inner groove 21.

[0037] Working principle: First, when locking the bottom mold 1 and the upper mold 2, the connecting column 4 is inserted into the connecting piece 3. At this time, the elastic force of the spring 6 pushes the push plate 7, causing the push column 8 to slide inside the fixed tube 10. This pushes the limit bead 9, and multiple limit beads 9 slide inside the fixed tube 10, thus fixing multiple connecting pieces 3. This ensures that the mold will not loosen during the stamping process, avoiding errors caused by mold displacement, and ensuring that the size and shape of the parts meet the design requirements. When it is necessary to demold the automotive structural parts, the electric push rod 17 is activated to push the push table 18, causing the push shaft 19 inside the push table 18 to move. The push shaft 19 slides inside the inner groove 21, which pushes the rotating frame 20. This causes the rotating frame 20 to drive the turntable 14 to rotate inside the fixed table 13 and change the tilt angle. Then, the demolding template 15 can be used for demolding, which significantly improves production efficiency, reduces manual intervention and operation time, and thus speeds up the production pace.

[0038] 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 and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
