The invention provides an automobile plating plate part stamping and powder removing test mold applied to the technical field of automobile plating outer plate part production, and also relates to anautomobile plating plate part stamping and powder removing test method. A female mold (4) is installed on a female mold mounting base (1), a male mold (5) is installed on a male mold mounting base (2), each female mold (4) and one male mold (5) form a female and male mold assembly (6), and a female mold concave groove (8) of the female mold (4) is arranged to be of a structure capable of being aligned to a male die convex block (10) on a male mold press-fitting face (9) of the male mold (5). The automobile plating plate part stamping and powder removing test mold comprises a plurality of female and male mold assemblies (6) and a plurality of test sample pieces (3). According to the automobile plating plate part stamping and powder removing test mold and the automobile plating plate part stamping and powder removing test method, the powder removing effect in different drawing rib states in the stamping process of various plating outer plates can be simulated, the cost for repeated modification of mold drawing ribs is reduced, and the overall quality of the coated outer plates is improved.
