Sleeper production mold

The utility model relates to the technical field of sleepers, and discloses a sleeper production die which comprises a rectangular beam frame and a plurality of steel die shells arranged in the rectangular beam frame in a matrix mode, and the rectangular beam frame comprises a tensioning end beam, a fixed end beam and a pair of long main beams, a tensioning box is arranged between the tensioning end beam and the steel formwork; a plurality of front and back steel mold shells located in the same row in the rectangular beam frame are communicated to form a long mold of an integral structure, and no partition plate is arranged in the middle of the long mold. A partition plate is not arranged in the middle of the long die of the sleeper, and the sleeper is produced in a long beam mode, so that the sleeper has the advantages of reducing uneven tension of steel wires, reducing prestress loss of the steel wires, simplifying the technological process, improving the integrity of the model, facilitating material distri
