PROBLEM TO BE SOLVED: To provide an apparatus for quickly and accurately controlling the inside temperature of the mold of a glass forming machine and stable molding of high quality glass forms. SOLUTION: In the glass forming process, modeling is done on the basis of calorie, which is applied to and emitted from molds 1 and 2, and a control part is designed by giving some factors of disturbance to the model and identification. Opening and shutting time of valves 7, 8 is decided on the basis of the inside temperature of the mold detected by the detecting means 27, 28 at a point in time, and at the same time, the opening and shutting time of valves is revised on the basis of changing amounts of the disturbance factors detected by disturbance detecting elements 30, 31.
