Abstract

PURPOSE:To control a temperature with high accuracy, by foreseeing a fault at the stage of its symptoms, and correcting a spot temperature in accordance with said symptoms. CONSTITUTION:An infrared sensor T1 and an injection temperature sensor T2 detect an instantaneous temperature of each spot in a prescribed molding cycle time, and these outputs which have been detected are digitally converted and are inputted to a microcomputer. The microcomputer automatically sets a level by a learning function as to a temperature range t0 in case opening and closing of a metallic mold, and an injection process are operated normally, operates a temperature of a fixed metallic mold 1 and a movable metallic mold 2, and also a variation value, a mean value, a dispersion value, a correlation, etc. of an injection temperature, analyzes by algorism which has been changed to an ROM in advance, and foresees a fault. Subsequently, from the microcomputer, a control signal for controlling a temperature adjusting means C of a metallic mold B is outputted in accordance with said foreseeing of a fault.
