Aluminum alloy profile extrusion die

The utility model provides an aluminum alloy profile extrusion die, which belongs to the technical field of extrusion dies and comprises a lower die, an upper die, a die core mechanism, a shunting mechanism, a locking mechanism, a limiting mechanism and a die core mechanism, the shunting mechanism is arranged inside the upper die and used for extruding metal, and the locking mechanism is arranged on the die core mechanism. The mold core has the beneficial effects that when the mold core is replaced, the shunting bridge is inserted into the slot in the mold core main body, then the threaded column extrudes the rod member connected with the hinging piece, and at the moment, the first hinging plate and the second hinging plate on the hinging piece are rotated and unfolded, and the first limiting piece and the second limiting piece are respectively inserted into the second limiting slot formed in the shunting bridge; and at the moment, the shunting bridge is mounted on the mold core main body, and then the shunti
