[0004] The technical solution adopted by the present invention is: a stamping mold for the front connecting plate of the battery pack mounting longitudinal beam, comprising a lower template, a die is arranged above the lower template, the die is rectangular as a whole, and is fixed to the lower template by screws, a groove I is arranged in the upper middle part of the die, the upper side wall of groove I is an inclined surface, the lower side wall and the left side wall are stepped inclined surfaces, and the right side wall of groove I is a vertical plane, a groove II is arranged in the middle and lower part of the die, the upper side wall and the left side wall of groove II are stepped inclined surfaces, and the lower side wall is an inclined surface, the depth of groove I and groove II is the same, a punch is arranged above the die, the punch is fixedly installed below the upper template, the punch is provided with a raised portion, and the contour of the raised portion is adapted to the contour of the recessed portion of the die.

[0005] A further technical solution of the present utility model is that a plurality of positioning blocks are provided on the die, and the positioning blocks are mounted on the die by screws, wherein the positioning block located on the left side of the die is in a "U" shape flipped 90 degrees clockwise, the positioning block located on the upper right side of the die is in a "7" shape, and the positioning block located on the lower right side of the die is in an "L" shape flipped 90 degrees counterclockwise.

[0006] A further technical solution of the present invention is: a pad is installed below the lower template, and a lower supporting plate is installed below the pad.

[0007] The beneficial effect of the present invention is that due to the adoption of the above technical solution, a battery pack mounting longitudinal beam front connecting plate stamping die of the present invention can quickly stamp out a battery pack mounting longitudinal beam front connecting plate, and the quality of the stamped workpiece is stable, which can greatly improve production efficiency.
