Most of the existing fiber forming dies use glass fiber as the main material, and the surface quality of the die is poor after long-term use, and the die is prone to deformation, which affects the surface quality of the workpiece and the service life of the die.

[0003] The Chinese patent with publication number CN110976659B discloses a forming die of a controllable deformation skin structure, which includes a pressing mechanism and a support and guide mechanism. The support and guide mechanism includes a guide frame, a first fixed frame and a separation assembly. The guide frame is arranged in the skin to be processed and used to support the skin to be processed. The first fixed frame is sleeved on the outside of the skin to be processed and is tightly connected with one end of the skin to be processed. A plurality of separation assemblies are sleeved on the skin to be processed and are arranged along the axial direction of the skin to be processed. The pressing mechanism is sleeved on the guide frame and abuts against the fixed frame. The forming die of the present application can fold the skin to be processed outward between adjacent separation assemblies through multiple extrusion and stretching, weaken the strength of the folded skin, and produce a controllable deformation skin structure.

[0004] In view of the problems existing in the existing forming die, the telemetry antenna support skin forming die structure provided by the utility model can be applied to composite material skin forming and other structural part production lines. Compared with the existing glass fiber forming die, the packaging box body forming die of the utility model is made of metal material, has high forming surface hardness and long service life, effectively improves the surface quality of the fiber product, effectively solves the problem of poor surface quality of the fiber product after forming, reduces the method of manually processing the surface roughness of the fiber product in the later stage, improves the mechanical properties of the workpiece, and further reduces the production cycle and manufacturing cost of the fiber workpiece.
