Furthermore, a yielding hole matched with the positioning pin is formed in the upper die punch.
Furthermore, the cross section of the upper die punch head is rectangular, and the abdicating holes are arranged side by side along the length direction of the upper die punch head.
Furthermore, the elastic block is provided with two mounting holes in a T shape, the positioning pin is arranged in the mounting holes in a limiting manner, and a set screw in threaded connection with the mounting holes is further arranged below the positioning pin.
Furthermore, the positioning blocks are respectively arranged in the lower templates at the left side and the right side of the accommodating hole, and the inner side surfaces of the positioning blocks are arc surfaces.
Furthermore, a guide mechanism is connected between the upper die holder and the lower die holder.
The utility model discloses a show the effect and be:
1. on the basis of the existing positioning of the positioning pin, the appearance auxiliary positioning is carried out through the arranged positioning block, the positioning effect is better, the phenomenon of unstable size caused by shaking after a product is placed in a die is avoided, and the quality of the processed product is effectively improved;
2. the lower die forming insert is convenient for adjusting the product forming size, so that the die can have higher processing precision.

Detailed Description
The following provides a more detailed description of the embodiments and the operation of the present invention with reference to the accompanying drawings.
As shown in fig. 2-5, an automobile back door fixing frame bending die comprises an upper die holder 1 and a lower die holder 5, wherein an upper die punch 7 is fixed on the lower surface of the upper die holder 1 through an upper backing plate 2, a lower die plate 3 is fixed on the lower die holder 5 through a lower backing plate 4, a containing hole 8 is formed in the center of the lower die plate 3, bending blocks 9 are arranged on the left side and the right side of the containing hole 8, limiting grooves 10 are formed on the opposite sides of the two bending blocks 9, an elastic block 11 is arranged between the bending blocks 9 on the two sides and located right below the upper die punch 7, protrusions on the two sides of the elastic block 11 are limited in the limiting grooves 10, a reset spring 12 is arranged below the elastic block 11, two positioning pins 13 are fixed in the elastic block 11, lower die insert blocks 14 are arranged on the front side and the rear side of the containing hole 8, a plurality of positioning blocks 15 are embedded in the lower die plate 3 of the containing hole 8, the inner side surfaces of the positioning blocks 15 are adapted to the shape of a back door to be processed, and a guiding mechanism is connected between the lower die holder 5 and the lower die holder 6.
In this example, the upper die punch 7 is provided with a relief hole 16 corresponding to the positioning pin 13, the cross section of the upper die punch 7 is rectangular, and the relief holes 16 are arranged side by side along the length direction of the upper die punch 7.
In this example, the specific mounting structure of the positioning pin 13 is: the elastic block 11 is provided with two T-shaped mounting holes, the positioning pin 13 is limited and arranged in the mounting holes, and a stop screw 17 in threaded connection with the mounting holes is further arranged below the positioning pin 13.
