The invention provides a strong plastic deformation extrusion method and a molding device for magnesium alloy band rib barrel-type part, belonging to the technical field of plastic processing. A columnar billet is subjected to channel-changing corner extrusion for the first time to extend to a circumferential direction to form a circular rib and then subjected to the channel-changing corner extrusion for the second time to enter an up-down mold cavity to form a thin-walled cylinder provided with four longitudinal ribs. When a material is subjected to corner extrusion for multiple times, crystalline grains are constantly refined to generate strong plastic deformation to cooperate with the mold cavity to realize extrusion molding once and obtain the high-strength magnesium alloy band rib barrel-type part. The length of a diameter fixing band of an extrusion mold is shrunk so as to reduce friction between a formed part and a mold to decrease forming force. A longitudinal pull rod and a transverse shaft pin for special purpose are designed and cooperate with a mold structure, and after part molding is completed, the return stroke of a workbench on an extruder is utilized to disassemblethe mold and take out the formed part. A magnesium alloy barrel-type part, which has high strength, can be molded once, a circular rib and longitudinal bars therein can be used as support structures,and the designed part taking structure can be used for effectively solving the problem that a barrel-type extrusion part is difficult to take out.
