Intramedullary nails, which are orthopedic internal fixation devices among medical instruments, are often used to join two fractured bones together during a fracture.

Because some bones are curved, the intramedullary nail needs to be shaped like the corresponding bone in order to be more suitable for the curved bone, and thus a curved intramedullary nail is needed, which is called an 'angle intramedullary nail' in the medical field.

According to the bending shape of the bone to be repaired, the bending characteristic of the angular intramedullary nail is formed by adopting a mould to press and bend. In the current mould for bending and forming intramedullary nail (refer to the attached figure 1 of the specification): the upper die and the lower die are both rigid, the arc-shaped bulge 61 protrudes from the top end of the rigid lower die 6, and the bottom end of the rigid upper die 7 is provided with an arc-shaped cavity matched with the arc-shaped bulge 61, so that the intramedullary nail is placed on the arc-shaped bulge 61 of the rigid lower die 6 firstly, and then the rigid upper die 7 is pressed down, so that the rigid upper die 7 and the rigid lower die 6 extrude the intramedullary nail, and the intramedullary nail is bent and formed by matching the arc-shaped cavity and the arc-shaped bulge 61.
