TEMPERATURE CONTROL DEVICE OF INJECTION MOLDING MACHINE HAVING TEMPERATURE CORRECTION FUNCTION AND TEMPERATURE CONTROL METHOD OF INJECTION MOLDING MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a temperature control device of an injection molding machine having a temperature correction function that can prevent temperature of a molten resin from becoming lower than preset temperature, and to provide a temperature control method of an injection molding machine.;SOLUTION: A heater 10 is mounted on a circumference of an injection cylinder 12 of an injection molding machine. Temperature of an injection cylinder 12 heated by the heater 10 is detected by a temperature detector 14. A temperature control device 8 performs temperature control of the heater 10 based on a temperature correction amount Tadj set by a temperature correction quantity setting part, preset temperature Ts set by a temperature setting part 4, and cylinder temperature Tc detected by the temperature detector 14. The temperature control device 8 performs temperature control of the heater 10 based on temperature deviation that is a value in which cylinder temperature Tc is subtracted from a value in which temperature correction amount Tadj and preset temperature Ts are added in a computing element 6. A screw (not illustrated) drive-controlled by a screw rotary drive part 16 is built in inside the injection cylinder 12.;COPYRIGHT: (C)2014,JPO&INPIT
