The invention relates to a magnetorheological porous soft mold and a plate forming device. The magnetorheological porous soft mold comprises an elastic base body with pores; and magnetic particles integrally formed in the elastic base body, wherein the magnetic particles are distributed in the elastic base body in a dispersed mode and located outside the pores. The elastic base body comprises at least two forming sections; all the forming sections are internally provided with the pores, and the porosity of at least one forming section is larger than that of the other forming sections, so that the elastic modulus of the forming sections with the large porosity is smaller than that of the forming sections with the small porosity; or at least one forming section is internally provided with the pores and at least one forming section is not internally provided with the pores, so that the elastic modulus of the forming sections with the pores is smaller than that of the forming sections without the pores. Through the design of the structure, when a blank is in complete contact with a special-shaped female mold, the stress of the whole blank is uniform, and the situation that the blank is broken due to the fact that the forming force is too large when a deeper part is formed is avoided.
