Extrusion die for use with extruder during pipe extrusion, has thermocouple element fastened at distance to intermediate bolt for arrangement of heating element, where temperature of bolt is measured by thermocouple element

摘要

The die has a base tool (5) provided with an intermediate bolt (5a) and an intermediate sleeve (5b), and a dimension-dependent nozzle insert provided with a bolt (6a) and a sleeve (6b), where the intermediate bolt and the bolt fix an inner contour of a plastic flow channel (7). The tool is connected with the insert. The intermediate bolt and the bolt are rotationally connected around a center axis (8). A thermocouple element (9) is fastened at a distance to the intermediate bolt for arrangement of a heating element (10), where temperature of the bolt is measured by the thermocouple element.
