PROBLEM TO BE SOLVED: To provide a method for automatically regulating a mold clamping force so that a crosshead may not overrun an origin when the mold clamping force is feedback controlled. SOLUTION: The method for automatically regulating the mold clamping force comprises the steps of previously setting the maximum mold clamping force and a criterion of the maximum mold clamping force, moving a mold clamping housing by a driving stroke amount in response to the maximum mold clamping force from the origin of the crosshead to regulate the clamping force, clamping the mold, measuring the real mold clamping force, again regulating the clamping force when the real mold clamping force is out of the criterion of the maximum mold clamping force, and changing the driving stroke amount until the real mold clamping force falls within the criterion of the maximum mold clamping force.
