Abstract

PURPOSE:To improve the temperature adjusting function of the screw remarkably by a method wherein a heat pipe of a specified constitution is accommodated in the screw for the extruder of plastics. CONSTITUTION:The heat pipe having the constitution described hereinafter is employed as the heat pipe accommodated in a receiving hole provided in the main body 1 of the screw. I: A container 2 provided with a groove type wick 3 at the inside thereof is penetrated through the whole length of the main body 1 of the screw, (however, one end of the container 2 is exposed to the outside of the main body 1). II: Provided at the outside of the container 2 are a liner 5 for improving heat conductivity at a measuring section A and a melting section B and an insulating layer 7 at a compression section C, a material supplying section D and a screw driving section E. III: At the inside of the wick 3, there are provided an operating liquid dispersing wick 4 at the measuring section A, the melting section B and a temperature adjusting section F while there are provided an evaporation preventing tube 6 for the operating liquid at a position between a part of the melting section B and the screw driving section E.
