[0002] like Figure 9 The battery module box shell shown in the figure needs to be individually flanged for molding in the existing molding process, so multiple sets of molds are needed to achieve molding. However, the multiple sets of molds need to be repeatedly positioned, which results in dimensional errors and makes it difficult to ensure the product size quality. At the same time, multiple devices are invested, and the cost investment is high, so there is a lot of room for improvement. Summary of the Invention
[0003] The purpose of the utility model is to solve the above problems in the prior art and to provide a one-step forming die for a battery module box shell.
[0004] The purpose of the utility model can be achieved through the following technical solutions: A battery module box shell one-time molding die, comprising:

[0006] An upper die base, which can be raised and lowered and moved closer to or away from the lower die base, and the upper die base is used to drive the workpiece and the floating plate and drive the floating plate closer to the lower die base;
[0007] The pendulum block is rotatably connected to the lower die base. The pendulum block is provided with a second linkage part and a bending part. When the floating plate approaches the lower die base, it drives the first linkage part to contact the second linkage part and can drive the pendulum block to rotate through the second linkage part, so that the bending part bends the workpiece.
[0008] The above-mentioned battery module box shell one-shot molding die further includes a first elastic member, both ends of which are in contact with the lower die base and the floating plate respectively, and the first elastic member drives the floating plate away from the lower die base.
[0009] In the above-mentioned one-step molding die for the battery module box shell, the lower die base is further provided with a guide hole, and the floating plate is further provided with a guide column, and the guide column is movably connected to the guide hole.
[0010] In the above-mentioned one-step molding die for the battery module box shell, the lower die base is further provided with a limiting column, and the limiting column can contact the floating plate to limit the minimum distance between the floating plate and the lower die base.
[0011] In the above-mentioned one-step molding die for the battery module box shell, a second elastic member is further included, wherein two ends of the second elastic member are in contact with the lower die base and the pendulum block respectively, and the second elastic member drives the pendulum block to contact the floating plate.
[0012] In the above-mentioned one-time molding die for the battery module box shell, the lower die base is further provided with a support block, the support block is provided with a force-bearing arc surface, and the pendulum block is provided with a force-applying arc surface. When the pendulum block rotates, the force-applying arc surface is always in contact with the force-bearing arc surface.
[0013] In the above-mentioned one-step molding die for the battery module box shell, the upper die base is provided with a pressing plate for contacting the workpiece.
[0014] In the above-mentioned one-time molding mold of the battery module box shell, it also includes a stripping drive element and a stripping block.

The stripping drive element can drive the stripping block to extend or retract the pressing plate.
[0015] In the above-mentioned one-step molding die for the battery module box shell, the lower die base is further provided with a chamfering block.
[0016] In the above-mentioned one-step molding die for the battery module box shell, the lower die base is further provided with a positioning block for positioning the workpiece.
[0017] Compared with the prior art, the beneficial effects of the present invention are:
[0018] 1. When the floating plate approaches the lower die seat, it drives the first linkage part to contact the second linkage part and can drive the pendulum block to rotate through the second linkage part, so that the bending part bends the workpiece to achieve one-time forming of the workpiece. At the same time, the negative swing angle of the pendulum block can be predetermined, so as to achieve the rotation compensation rebound angle.
[0019] 2. The first elastic member drives the floating plate away from the lower die base so that it will not accidentally trigger the pendulum block due to its own gravity. At the same time, it continuously applies a force to the floating plate to overcome the force applied by the first elastic member to drive the floating plate down.
[0020] 3. The limit column can contact the floating plate to limit the minimum distance between the floating plate and the lower die base, thereby limiting the maximum swing angle of the pendulum block, and further limiting the rebound angle compensation of the workpiece.
[0021] 4. The second elastic member drives the pendulum block to contact the floating plate, thereby assisting in pushing the floating plate to a normally raised state, while continuously applying a force to the pendulum block. The floating plate overcomes the force applied by the second elastic member to drive the pendulum block to rotate.
[0022] 5. When the pendulum block rotates, the force-applying arc surface is always in contact with the force-receiving arc surface, which greatly reduces the force on the connection between the pendulum block and the lower die base, prevents the pendulum block from being damaged by excessive force, and makes the movement of the pendulum block more stable.

[0042] Among them, the pendulum block 300 is rotatably connected to the lower mold base 100, and the pendulum block 300 is provided with a second linkage part 310 and a bending part 320. When the floating plate 110 approaches the lower mold base 100, it drives the first linkage part 111 to contact the second linkage part 310 and can drive the pendulum block 300 to rotate through the second linkage part 310, so that the bending part 320 bends the workpiece.
[0043] In this embodiment, when the floating plate 110 approaches the lower mold base 100, it drives the first linkage part 111 to contact the second linkage part 310 and can drive the pendulum block 300 to rotate through the second linkage part 310, so that the bending part 320 bends the workpiece to achieve one-time forming of the workpiece. At the same time, the negative swing angle of the pendulum block 300 can be predetermined, so that the rotation compensation rebound angle can be achieved.

[0045] In this embodiment, the first elastic member 400 drives the floating plate 110 away from the lower mold base 100, so that it will not mistakenly trigger the pendulum block 300 due to its own gravity. At the same time, it continues to apply a force to the floating plate 110 to overcome the force applied by the first elastic member 400 to drive the floating plate 110 down.

[0051] In this embodiment, the second elastic member 500 drives the pendulum block 300 to contact the floating plate 110, thereby assisting in pushing the floating plate 110 to a normally raised state, while continuously applying a force to the pendulum block 300. The floating plate 110 overcomes the force applied by the second elastic member 500 to drive the pendulum block 300 to rotate.
