The utility model relates to a mold, especially, relate to a tensile plastic hole flanging backhand mould structure that punches a hole for making braking housing, top -down includes mounting plate, last cushion, upper die base, die holder in proper order, descends cushion and bottom plate, be equipped with the tensile mould structure that sets up side by side, plastic mould structure between upper die base and the die holder, towards mesopore mould structure, mesopore mould structure and mesopore backhand mould structure turn over. The utility model discloses a tensile mould structure brings into the material and goes upwards tensilely, and the shape is adjusted to the braking housing after adopting plastic mould structure to drawing, adopt towards mesopore mould structure to braking housing towards mesopore, adopt and turn over mesopore mould structure and carry out the hole flanging to the mesopore of braking housing, adopt mesopore backhand mould structure to carry out backhand to the mesopore of braking housing, not only simple structure, convenient to use just can improve preparation efficiency, reduction die sinking cost so that braking housing assembly line is made.
