The utility model relates to the field of thin plate powder forming, in particular to a die for direct pressing production of a cold isostatic pressing thin square plate. Comprising a mold base, a flexible mold sleeve and a mold cover plate, a pressure cavity is formed in the middle of the mold base, and a pressure through hole is formed in the mold base. The flexible mold sleeve comprises a matching part and a mold cavity part which are integrally formed, the matching part is located on the periphery of the mold cavity part, and the matching part is matched with the peripheral edge of the pressure cavity of the mold base in a nested mode. And the peripheral edges of the mold cover plate and the mold base are fastened and mounted through fasteners. According to the die, unique structural design is adopted, direct cold isostatic pressing die forming can be conducted on a powder thin plate, then a final finished product is obtained through sintering, the production efficiency is obviously improved, the linear c
