The invention discloses a mold for forming a composite material rectangular beam through wet winding and a use method of the mold. The rectangular mold is mounted on a winding machine after the outersurface of the rectangular mold is sleeved with a sealing layer; fiber laying layers on the outer surface of the rectangular mold are designed according to the thickness of the four corner areas of aproduct, wet winding is carried out, and combined outer molds are mounted on the four side surfaces to extrude the fiber laying layers to a designed boundary dimension after the winding is completed;and finally, the whole enters a curing oven for curing, demolding is conducted after curing is completed, and the outer surface of the rectangular beam product is corrected. Through the design of themold and the improvement of the process, the central areas of the four sides of the prepared rectangular beam product protrude inwards, the outer surface of the rectangular beam is regular, the processing of the outer surface is
