The utility model relates to a combined sampling cup. The combined sampling cup comprises a cup-shaped sand mold and a sand mold holder, wherein a cavity is formed in the center of the sand mold holder, the cup-shaped sand mold can be accumulating in the cavity, after the cup-shaped sand mold is placed in the sand mold holder, a gap is reserved between the cup-shaped sand mold and the sand mold holder, the cup-shaped sand mold and the sand mold holder are molded through casting with alkaline phenol resin sand as a medium, and the wall thickness of the cup-shaped sand mold is not greater than 10 mm. The combined sampling cup disclosed by the utility model has the benefits that the cavity formed in the center of the sand mold holder can be used for accumulating the cup-shaped sand mold, the gap is reserved between the cup-shaped sand mold and the sand mold holder after the cup-shaped sand mold is placed in the sand mold holder, and the wall thickness of the cup-shaped sand mold is not greater than 10 mm, so that gas generated by using high temperature liquid steel for baking a sand mold can be rapidly exhausted through the gap, the influence of the gas on the liquid steel is eliminated, the liquid steel can really reflect the own gas content, and an objective and real result is obtained.
