[0005] A further technical solution of the present utility model is: a positioning block is also provided on the die, and the positioning block is installed on the die by screws. The number of the positioning blocks is 8, of which 4 are located on the left half of the die, and 4 are located on the right half of the die. The positions of the positioning blocks on the left half of the die are symmetrical with those on the right half of the die.

[0006] A further technical solution of the present invention is: a plurality of pads are installed below the lower template, and a support plate is fixedly installed below the pads.

[0007] The beneficial effect of the present invention is that: due to the adoption of the above-mentioned technical scheme, a left rear upper outer panel punching and forming die of the present invention can punch out a left rear upper outer panel and a right rear upper outer panel of a car after performing one stamping action. The punching action is also completed at the same time as the stamping and forming is completed, which can effectively improve production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
