TEMPERATURE REGULATING SYSTEM FOR MOLDING MATERIAL CHARGING PART

摘要

PROBLEM TO BE SOLVED: To provide a temperature regulating system for a molding material charging part which can meet zero emission without putting out a fluid such as water from outside and moreover hardly causes problems in an electric system of a molding machine. SOLUTION: The temperature regulating system 10 is provided for keeping the molding material charging part 1 charging a molding material m in a screw SC of the resin molding machine C at a prescribed temperature. A closed temperature regulating pipeline system 6 is constituted by connecting by a pipeline an in-shell pipeline 1b running through a shell body 1a of the charging part 1 and a temperature regulating part 5 equipped with a reflux pump 3 and a temperature regulator 2. While a refrigerant W is refluxed through the temperature regulating pipeline system 6 by the reflux pump 3, the temperature of the refrigerant W is regulated by the temperature regulator 2 and thereby the molding material charging part 1 is kept at the prescribed temperature.
