PROBLEM TO BE SOLVED: To solve such a problem that the deterioration of the degree of parallelization of molds, that is, the thickness irregularity of a molded article is easy to generate in a direct pressure type mold clamping apparatus though there are many beneficial points from an aspect of molding in this apparatus. SOLUTION: The mold clamping apparatus is constituted of a mold clamping mechanism for allowing mold clamping force to act on the center part of a movable platen, a plurality of auxiliary clamping mechanisms for allowing mold clamping force to act across the movable platen and a fixed platen, detectors for detecting the distance between the movable platen and the fixed platen corresponding to the auxiliary clamping mechanisms, and a control unit for controlling the auxiliary clamping mechanisms so that the signals from the detectors become equal.
