The invention relates to a die sleeve device for preventing edge outgoing during tire bead vulcanization. The die sleeve device comprises a die sleeve body, wherein the die sleeve body is formed by splicing a first semicircular die sleeve and a second semicircular die sleeve, wherein the inner side of each of the first die sleeve and the second die sleeve is formed to be groove-shaped; the first die sleeve comprises a first connection part, a first upper edge and a first lower edge are arranged at an upper end and a lower end of the first connection part respectively, and the included angle between the upper edge and the lower edge is 75-80 degrees; and the second die sleeve comprises a second connection part, a second upper edge and a second lower edge are arranged at an upper end and a lower end of the second connection part respectively, and the included angle between the second upper edge and the second lower edge is 75-80 degrees. The die sleeve device disclosed by the invention is simple in structure, ingenious in design, capable of preventing remainder rubber materials from entering gaps between steel zero rings and capsules to cause an edge outgoing phenomenon of a tire bead during the tire bead vulcanization, and then increasing the pass percentage of products during the vulcanization process, and convenient to detach.
