Among them, the second forming area, the third forming area, and the fourth forming area all control the two ends of the rear shell to bend upward, and the fifth forming area and the sixth forming area control the two ends of the rear shell to bend inward.

[0007] As a preferred technical solution, it includes an upper cover plate and an upper die base. The upper cover plate is located above the upper die base, and the upper die base is located above the clamping plate.

[0008] As a preferred technical solution, it includes an upper backing plate, and the upper backing plate is located between the upper die base and the clamping plate.

[0009] As a preferred technical solution, it includes a lower backing plate and a lower die base, and the lower backing plate is located between the lower template and the lower die base.

[0010] As a preferred technical solution, a stop plate and a stripper plate are arranged between the clamping plate and the lower template.

[0011] The beneficial effects of the present utility model are as follows: A forming die for the rear housing of a data transmission line is provided. By setting different forming areas between the clamping plate and the lower template, both ends of the rear housing are bent upward from a flat state and then bent inward to form a circular sleeve-like structure, and the required finished rear housing is integrally produced, eliminating the need for multiple sets of dies for processing and saving resources.
