TEMPERATURE CONTROLLING APPARATUS FOR INJECTION MOLDING MACHINE AND METHOD OF DRIVING THE SAME

摘要

A temperature controlling apparatus for an injection molding machine according to the present invention comprises a first large power controlling unit and a second large power controlling unit which are connected between a power supply unit and a hot runner and control the electricity supplied to the hot runner by the control of a center processing unit; a first temperature sensing unit which senses the current temperature of the hot runner; a second temperature sensing unit which senses the internal temperature of a case covering the first large power controlling unit and the second large power controlling unit; a display unit which displays the desired temperature and current temperature of the hot rubber, the internal temperature of the case and the chance notification of the first large power controlling unit and the second large power controlling unit; a warning unit which serves a disconnection condition of the first temperature sensing unit or a warning corresponding to the disconnection condition; and the center processing unit which controls the first large power controlling unit, the second large power controlling unit, the first temperature sensing part, the second temperature sensing part, the display unit and the warning unit.
