The invention discloses a two-side hanging-holding exhibition aluminum alloy extrusion plate die. The two-side hanging-holding exhibition aluminum alloy extrusion plate die is characterized in that the die comprises obverse side plate flow channels and reverse side plate flow channels; obverse side plates are arranged in an equally spaced mode in the flow channel width direction, and the gaps between the reverse side plate flow channels and the obverse side plate flow channels in the width direction are arranged oppositely in an equally spaced mode; two vice reverse plate flow channels are arranged at the two ends in the arrangement direction of the reverse side plate flow channels respectively; the edges of the outer sides, in the arrangement direction, of the vice reverse plate flow channels are connected with connection plate flow channels respectively; the two connection plate flow channels are provided with convex edges and concave flow channels respectively, and the convex edges and the concave flow channels are of the same outlines respectively; the two edges, in the arrangement direction, of the reverse side plate flow channels are connected with the edges of the obverse side plate flow channels on the two sides of the gap between the obverse side plate flow channels which the reverse side plate flow channels face through inner connection plate flow channels respectively; the included angles between the inner connection plate flow channels and the obverse side plate flow channels are 60 degrees; the needed extrusion pressure is small; a wall face is neat and has good texture; the decorativeness is improved; the structure is stable.
