PROBLEM TO BE SOLVED: To provide a mold clamping control method capable of preventing the plastic deformation of a mold caused by the flash formed by reducing mold clamping force at the time of abnormality of injection pressure to consequently suppress the occurrence of the flash, and a mold clamping device used therein. SOLUTION: An in-mold pressure sensor 30 is provided in the mold and an in-mold pressure value obtained at the time of abnormality of injection pressure is set to a memory 41. Then, in-mold pressure is detected by the in-mold pressure sensor 30 and, when the detected value reaches a preset in-mold pressure value or above during a mold clamping state, the mold is opened by a predetermined quantity to reduce mold clamping force.
