Extrusion shaping die

The utility model discloses an extrusion shaping die. A cavity is formed in the middle of the extrusion shaping die; at least one narrow part is arranged on the periphery of the cavity; blowing plates are arranged in the positions, corresponding to the at least one narrow part, of an inlet end surface of the extrusion shaping die; flow channels are arranged in the blowing plates; opening slots communicated with the flow channels are formed in the at least one narrow part; and the flow channels are connected with a cold air device. According to the extrusion shaping die, air flow blown from the cold air device enters the channels of the blowing plates and is blown to the narrow parts of a profile through the opening slots communicated with the flow channels, so that the narrow parts of the profile about to enter the cavity are cooled in advance, accordingly, the profile passes the extrusion shaping die more easily, the blockage is prevented, and the production continuity is guaranteed.
