The invention relates to a novel casting technique of a semitrailer brake drum. The novel casting technique of the semitrailer brake drum comprises the following steps of: manufacturing an inner mold shell and a pouring cup; regulating the temperature of an iron mold, covering with sands, and modeling; checking by turning over a mold; assembling a shell mold; filling iron shots; pouring and cooling; turning over the mold, discharging elements, assembling the elements, and recovering; carrying out magnetic separation, and screening; dedusting and cleaning. No deformation of the brake drum is ensured fully; the steel shots are filled in an internal mold sand shell; poured steel liquids generate pressure inward; firstly, because of the 'arch bridge principle', the internal mold sand shell has great support force; and then the steel shots also can block the pressure by steel liquids, and the internal mold sand shell cannot be cracked or deformed absolutely. Before cast elements are condensed and contracted, the internal mold sand shell is scattered, the filled steel shots are at the scattered state, the deformability of the cast elements in contraction is ensured fully, so that free contraction instead of hindered contraction is formed; a bottom-pouring-type pouring mode is adopted, air is discharged smoothly; the cracking possibility at the crossed part is reduced; air holes of the cast elements caused by dampness of a sand mold are prevented; the novel casting technique of the semitrailer brake drum is an environment-friendly casting technique.
