PROBLEM TO BE SOLVED: To provide a method for controlling an injection molding machine capable of continuous molding in which the quality of a molding is always stabilized even when a molding of a complex shape, in which thin wall parts and thick wall parts are mixed, is molded. SOLUTION: The first feedback system 11 which outputs a command value to a servo valve for a mold clamping cylinder based on the difference between the set value and detected value of a mold clamping cylinder pressure, the second feedback system 12 which outputs a command value to the servo valve for the mold clamping cylinder based on the difference between the set value and detected value of a mold opening quantity, and the third feedback system 13 which outputs a command value to the servo valve for the mold clamping cylinder based on the difference between the set value and detected value of a mold pressure are provided. The first to third feedback systems can be changed over automatically by a control program which is set up optionally by an operator or set up in advance.
