[0002] PU material is the full name of polyurethane, which is a high polymer material formed by polyol and polyisocyanate through polycondensation reaction and has excellent mechanical properties. It has very strong plasticity. Several main classifications of polyurethane include polyether type, polyester type, polyimide type, and polyurea type. They can be made into polyurethane plastic, polyurethane fiber, polyurethane rubber, and elastomer materials. By relying on the pressure and shear force generated by the rotation of the screw, the material can be fully plasticized and uniformly mixed. Through the die forming, the plastic material enters the extruder from the hopper. During the production of PU pipe, it is driven forward by the rotation of the screw. The material receives the heating of the barrel, the shear and compression effect of the screw, and melts. Under the condition of pressure, the material in the viscous flow state passes through the die with a certain shape, and then becomes a continuous body similar to the cross section of the die. Thus, the required pipe fitting is obtained.
[0003] However, in the prior art, slag accumulation occurs at the forming die during the production of PU pipe, which causes the slag to adhere to the surface of the pipe during the extrusion of the PU pipe, resulting in poor product appearance and appearance rejection. CONTENT OF THE INVENTION
