A plastic mold of a double-limiting structure comprises a fixing plate, a first groove is formed in the upper end of the fixing plate, a bidirectional threaded rod is arranged in the fixing plate, a movable plate is arranged at the upper end of the fixing plate, a fixing frame is fixedly connected to the center of the upper end of the fixing plate through a bolt, a bottom mold is arranged on the fixing frame, and a groove is formed in the bottom side of the bottom mold. Through holes are evenly formed in the positions, located on the two sides of the groove, of the bottom die, the two movable plates can be driven to get close to each other by rotating the two-way threaded rod, and therefore the upper side of the die can be fixed and limited, meanwhile, the die can be limited in the longitudinal direction through the extrusion plate, and the problems that at the present stage, a plastic die is not tightly clamped, and liquid leakage is likely to happen are greatly solved; meanwhile, the problems that a plastic
