[0009] Furthermore, each of the mounting slots is provided with a sliding groove on both sides, and each of the buffer blocks is provided with a protrusion corresponding to the sliding groove on both sides, and each protrusion matches the corresponding sliding groove.

[0010] Furthermore, the base is provided with a connecting groove for the lower mold, and the lower mold is inserted into the connecting groove and fixed to the base by fixing bolts.

[0019] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0020] Combination Figure 1 and Figure 2 As shown, a stamping die for manufacturing a flame retardant for a new energy vehicle battery pack includes a lower die 2 disposed on the top of a base 1 and an upper die 4 disposed on the bottom of a slider 3.

[0021] The lower mold 2 and the upper mold 4 are respectively provided with corresponding bosses 5 and grooves 6. The bosses 5 and grooves 6 of the lower mold 2 and the upper mold 4 are respectively connected in a wave shape. The lower mold 2 and the upper mold 4 are also respectively telescopically connected with buffer blocks 7 at the positions corresponding to each groove 6. The ends of the buffer blocks 7 are respectively provided with V-shaped grooves.

[0022] When the upper mold 4 and the lower mold 2 are closed, each of the buffer blocks 7 shrinks and the two sides of the V-shaped groove at its end are flush with the two sides of the inclined surface.

[0023] When the upper mold 4 and the lower mold 2 open, each of the buffer blocks 7 extends out and the V-shaped grooves at their ends protrude on both sides of the inclined surfaces.

[0024] The front end of the base 1 is also provided with a pair of guide blocks 9 corresponding to the processed plate 8, and the rear end of the base 1 is also provided with a limiting block 10 corresponding to the processed plate 8.

[0025] The working principle of the above structure is as follows: Initially, the slider 3 and the upper die 4 are in the raised state. The plate 8 is placed into the lower die 2 from the front end of the base 1. After placement, the rear ends of the plate 8 are limited by two guide blocks 9, and the front end of the plate 8 abuts against the limiting block 10. The entire plate 8 is supported on each support platform of the lower die 2. During stamping, the slider 3 drives the upper die 4 to move downward until the upper die 4 and the lower die 2 close, stamping the plate 8 into a corrugated plate. During the stamping process, due to the buffer blocks 7 set at the corresponding grooves 6 on the lower die 2 and the upper die 4, the plate 8 is smoothly stamped into a corrugated shape and is not prone to springback. Furthermore, since the front end and rear ends of the plate 8 are limited by the limiting block 10 and the guide block 9 respectively in the early stage of stamping, the plate 8 is not prone to displacement before being stamped, which can ensure the accuracy of the plate 8 during processing.

[0026] The advantages of the above structure are: it is simple to construct and can be mass-produced for the corrugated plates of flame retardants for new energy vehicle battery packs. Compared with processing by bending machine, it has the advantage of high processing efficiency and can also ensure a certain level of processing accuracy.

[0027] In another embodiment, such as Figure 1 As shown, the upper mold 4 and the lower mold 2 are respectively provided with mounting slots for corresponding buffer blocks 7 at the grooves 6. Multiple columns 11 are fixed in each mounting slot. Springs 12 are respectively sleeved and fixed on each column 11. The ends of each spring 12 are connected to the buffer blocks 7. When the upper mold 4 and the lower mold 2 are closed, the buffer blocks 7 abut against the ends of the columns 11, so that each buffer block 7 can be extended and retracted. When the upper mold 4 and the lower mold 2 are closed, each column 11 provides support for the buffer blocks 7.

[0028] In another embodiment, such as Figure 1 As shown, each of the mounting slots is provided with a sliding groove on both sides, and each of the buffer blocks 7 is provided with a protrusion corresponding to the sliding groove on both sides. Each protrusion matches the corresponding sliding groove to ensure the stability of the buffer block 7 when it extends or retracts.

[0029] In another embodiment, combined Figure 1 and Figure 2As shown, the base 1 is provided with a connecting groove for the lower mold 2. The lower mold 2 is inserted into the connecting groove and fixed to the base 1 by fixing bolts, so as to facilitate the quick installation and disassembly of the lower mold 2.

[0030] In another embodiment, such as Figure 1 As shown, the base 1 is provided with a bracket, which consists of four guide rods 13 and a top plate 14. A hydraulic cylinder 15 is fixed on the top of the top plate 14, and the piston rod of the hydraulic cylinder 15 is connected to the slider 3.

[0031] In another embodiment, such as Figure 1 As shown, the slider 3 has guide holes at its four corners corresponding to each guide rod 13. Each guide rod 13 passes through the corresponding guide hole to ensure the stability of the slider 3 when it moves up and down.

[0032] In another embodiment, such as Figure 1 As shown, when the upper mold 4 and the lower mold 2 are closed, the tops of the two guide blocks 9 and the limiting block 10 maintain a distance from the upper mold 4 to avoid affecting the closing of the upper mold 4 and the lower mold 2.

[0033] In another embodiment, combined Figure 1 and Figure 2 As shown, the two guide blocks 9 and the limiting block 10 are respectively fixed to the base 1 by screws. The positions of the two guide blocks 9 and the limiting block 10 are adjustable to adapt to the processing of various specifications of sheet metal 8.
