The efficiency and quality stability of its manufacturing are becoming increasingly important.

[0003] As the primary protection for batteries, the battery casing of new energy vehicles undergoes a highly rigorous manufacturing process. Currently, battery casing production is mostly carried out using stamping equipment. Conventional stamping equipment requires additional lubrication structures during the stamping and stretching process to lubricate the punch and die, preventing difficulties in removing the battery casing and ensuring production efficiency. Since the punch is generally the upper die and the die is generally the lower die, lubrication of the lower die is more difficult than that of the upper die, and it is mostly done manually, which carries a certain degree of danger.

[0004] Currently used stamping dies for battery pack casing processing mostly have complex and fixed connections with the press. When changing dies, it often requires professional technicians to spend a lot of time and effort to disassemble numerous bolts, nuts and other connecting parts. In addition, the installation position of the die on the press needs to be repeatedly adjusted to ensure that it is precisely matched with the stamping action of the press. This can easily lead to excessive downtime of the production line, which seriously affects production efficiency and increases production costs. To address these issues, a stamping die for processing new energy battery pack casings is proposed. Utility Model Content

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of a stamping die for processing new energy battery pack housings, including a fixed frame 1 and a worktable 6. A fixed plate 8 is fixedly connected to the top of the fixed frame 1, and a cylinder 9 is fixedly connected to the outside of the fixed plate 8. A disassembly component is installed at the end of the cylinder 9. The disassembly component allows for flexible adjustment of the die's function to meet the processing requirements of different battery pack housing models and processes, effectively improving the die's adaptability. A lower die 5 is fixedly connected to the outside of the worktable 6. A demolding component is installed inside the lower die 5. The demolding component allows the workpiece to be smoothly removed from the die, avoiding production interruptions caused by the difficulty in demolding the workpiece. The disassembly component includes a connecting plate 2. The top of the connecting plate 2 is fixedly connected to the end of the cylinder 9. The cylinder 9 drives the connecting plate 2 to impact the workpiece downwards. A housing 10 is fixedly connected to the bottom of the connecting plate 2. A circular locking block 16 is fixedly connected inside the housing 10. A connecting column 20 is rotatably connected inside the circular locking block 16. A sliding groove 17 is provided on the outside of the connecting column 20. A spring rod 18 is fixedly connected inside the slide groove 17, and a trapezoidal locking block 19 is fixedly connected to the end of the spring rod 18. By rotating, the circular locking block 16 slides in the slide groove 17. When it slides to the groove, the spring rod 18 drives the trapezoidal locking block 19 to engage. A support rod 7 is fixedly connected to the outside of the fixing frame 1. An upper mold 3 is slidably connected inside the support rod 7. By rotating the upper mold 3, the spring rod 18 will drive the trapezoidal locking block 19 downward under the action of force, so that the circular locking block 16 slides inside the slide groove 17 until it disengages, separating the upper mold 3 from the connecting plate 2. This facilitates the replacement of stamping die components of different shapes and sizes for different battery pack designs, making replacement more convenient and effectively improving the adaptability of the mold. A positioning pin 4 is fixedly connected to the outside of the upper mold 3. The positioning pin 4 can effectively prevent the mold from shifting during the stamping process. The bottom of the connecting column 20 is fixed to the outside of the upper mold 3. The circular locking block 16 is externally slidably connected to the inside of the slide groove 17. The circular locking block 16 is in contact with the surface of the trapezoidal locking block 19. The trapezoidal locking block 19 is used to fix the circular locking block 16 to prevent the mold from falling off during stamping and causing an accident that threatens the personal safety of the workers.

[0034] Reference Figure 2 and Figure 3The demolding assembly includes a spring 12, which is fixedly connected inside the lower mold 5. A push rod 14 is fixedly connected to the top of the spring 12, and a top plate 13 is fixedly connected to the end of the push rod 14. The upper mold 3 is driven downwards by a cylinder 9 to impact. Under the impact force, the spring 12 slides downwards along with the top plate 13. After the impact is complete, the spring 12 drives the push rod 14 and the top plate 13 to rise simultaneously, and the multiple top plates 13 lift the molded battery pack housing adhered to the cavity, allowing the adhered portion between the battery pack housing and the lower mold 5 to detach promptly. Multiple through holes 15 are opened in the middle of the lower mold 5, and the push rod 14 is slidably connected inside the through holes 15. Multiple positioning holes 21 are opened on the outside of the lower mold 5. After the mold needs repair, adjustment, or replacement of parts, it needs to be reinstalled and adjusted. The presence of positioning pins 4 and positioning holes 21 allows the mold to quickly and accurately return to its original installation position, ensuring repeatability. Fixing bolts 11 are fixedly connected to the outside of the worktable 6.

[0035] Working principle: By rotating the upper mold 3, the spring rod 18, under the action of force, will drive the trapezoidal locking block 19 downward, causing the circular locking block 16 to slide inside the slide groove 17 until it disengages, separating the upper mold 3 from the connecting plate 2. This facilitates the replacement of stamping die components of different shapes and sizes for different battery pack designs, making replacement more convenient and effectively improving the adaptability of the mold. During stamping, the positioning pin 4 is a key component that ensures the precise installation of each component of the mold by aligning with the positioning hole 21. Under high-speed stamping, it can effectively prevent the mold from shifting during the stamping process. The cylinder 9 drives the upper mold 3 to impact downward. Under the action of the stamping force, the spring 12 slides downward with the top plate 13. After the stamping is completed, the spring 12 drives the ejector rod 14 and the top plate 13 to rise simultaneously. The multiple top plates 13 lift the formed battery pack shell that is attached to the cavity, so that the glued part between the battery pack shell and the lower mold 5 is separated in time, making it convenient for the staff to directly remove the battery pack shell without the need for manual tools.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
