Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
Please refer to Fig.1~4, in the utility model embodiment, a kind of precise forming mold with step bending structure, packet
Lower die holder 1, upper die holder 2, lower mold core 3, upper mold core 4 and movable holddown 5 are included, mounting groove is provided in lower die holder 1 and upper die holder 2,
Lower mold core 3 is mounted on by mounting groove in lower die holder 1, and upper mold core 4 is mounted on by mounting groove in upper die holder 2, and the lower die
The side of seat 1 and upper die holder 2 is both provided with screw hole, and the first fixed screw 6 is fixed lower mold core 3 by the screw hole on lower die holder 1
On lower die holder 1, upper mold core 4 is fixed on upper die holder 2 by the second fixed screw 7 by the screw hole on upper die holder 2；
