The sound insulation sheet extruder head and die head are composed of an alloy steel inner sleeve and a carbon steel outer sleeve, and a forming mold is installed in the machine head. The function of the machine head is to convert the rotating plastic melt into parallel linear motion, introduce it evenly and smoothly into the mold set, and give the plastic the necessary molding pressure. The plastic is plasticized and compacted in the barrel, and flows into the machine head forming mold through the porous filter plate along a certain flow channel through the machine head and neck. The mold core and mold sleeve are properly matched to form an annular gap with a continuously decreasing cross-section, so that the plastic melt can A continuous and dense tubular coating is formed around the core wire. In order to ensure that the plastic flow channel in the machine head is reasonable and eliminate dead corners where plastic accumulates, a diverter sleeve is often installed. In order to eliminate pressure fluctuations during plastic extrusion, a pressure equalizing ring is also installed. The machine head is also equipped with a mold correction and adjustment device to facilitate adjustment and correction of the concentricity of the mold core and mold sleeve.
