The invention provides a die for manufacturing a blocking tool for a blast furnace tuyere. The die is a columnar cup body (1) with an elliptic cross section. An opening (11) is formed in the top of the cup body (1). The long axis of the bottom of the cup body (1) is 20-25 mm shorter than the long axis of the opening (11). The section area of the blast furnace tuyere is between the area of the opening (11) and the area of the bottom of the cup body (1). The cup body (1) is made of metal. By means of the die, the tuyere blocking work efficiency can be easily improved, the influences on the environment are reduced, and materials, time and labor are prevented from being wasted. 本发明提供了种制作高炉风口用封堵工具的模具，所述模具为具有椭圆横截面的柱体形的杯体(1)，所述杯体(1)的顶部具有敞口(11)，且所述杯体(1)的底部的长轴比所述敞口(11)的长轴小20mm～25mm，高炉风口的截面面积介于所述敞口(11)的面积和所述杯体(1)的底部的面积之间，所述杯体(1)由金属制作。本发明提供的模具有利于提高堵风口工作的效率，降低对环境的影响，避免浪费材料、时间和人力。
