Shaping sleeve of plastic extruding machine

The utility model discloses a shaping sleeve of a plastic extruding machine, which belongs to the technical field of plastic extruding machines and is technically characterized by comprising a sleeve body, a flange plate, a body mechanism and a water passing mechanism. A water passing mechanism used for spraying and cooling according to the positions of the sleeve bodies at different distances is arranged in the flange plate, and shaping holes are formed in the sleeve bodies. The outer thread ring arranged on the outer wall of the left end of the sleeve body is meshed with the inner thread groove formed in the flange plate, independent disassembly and replacement are facilitated, the water passing distances are different due to the fact that the sizes of the penetrating holes are different and the water passing pressures are different, and therefore the right end of the sleeve body can be effectively sprayed and cooled. And more balanced cooling treatment is carried out on the extrusion material in the shapin
