The invention discloses a combined type blind window for a railway boxcar and a forming apparatus thereof. The combined type blind window for a railway boxcar comprises an outer window and an inner window, wherein the inner window comprises an inner frame body and a plurality of inner gate sheets which are arrayed in the inner frame body in parallel and are integrally molded with the inner frame body; the outer window comprises an outer frame body which is used for mounting the inner window and a plurality of outer gate sheets which are arrayed in the outer frame body in parallel and are integrally molded with the outer frame body; each inner gate sheet is provided with an outer inclined face which is inclined to a slanting low direction; each outer gate sheet is provided with an inner inclined face which is inclined to a slanting low direction; and the numbers of the inner gate sheets and the outer gate sheets are equal and the inner gate sheets and the outer gate sheets are corresponding one to one, so that ventilation gaps are formed between the outer inclined faces of the inner gate sheets and the inner inclined faces of the outer gate sheets, which are mutually corresponding. After the structure is adopted, when rain and mist enter along the airflow, the rain and the mist are hindered by multistage S bends, so that the rain and the mist in the airflow are adhered to the S bends, a rain and mist prevention effect is achieved, and the use effect is good; in addition, the forming is simple; the demolding is convenient; and the manufacturing cost is greatly reduced.
