The invention relates to a forming moldand process of a continuous fiber-reinforced ceramic filtering element. The forming mold includes a pipe body with the diameter being 30-120 mm, a plurality of perforations evenly distributed on a main body of the pipe body are formed in the pipe body, the diameter of the perforations is 2-3 mm, and the spacing is 5-10 mm; the diameter and spacing of the perforations are verified by a large number of technological experiments according to the diameter and length of the pipe body, if the diameter of the perforations is less than 2 mm, the perforations areprone to being blocked by slurry and difficult to suck, filter and clean in the forming process, if the diameter of the perforations is more than 3 mm, the fact of uneven suction filtration and even difficult demolding can be caused, if the spacing of the perforations is less than 5 mm, the conditions that the suction filtration intensity is too great, the density of a green body is increased, theair permeability is affec
