PROBLEM TO BE SOLVED: To provide a method for preventing the falling of molds in the magnetic clamp of an injection molding machine or the like, capable of preventing the falling of the molds from both of a fixed platen and a movable platen by controlling mold release force and ejection force at the time of mold release and ejection. SOLUTION: In the method for preventing the falling of the molds in the magnetic clamp of the injection molding machine or the like by clamping the molds to both of the fixed platen and the movable platen by magnetic force, the mold release force for opening the molds 2 and 4 after mold clamping of the injection molding machine or the like is controlled so as not to exceed the clamp force Fn predetermined by the contact areas Sn of the molds coming into contact with both of the fixed platen 1 and the movable platen 3.
