PROBLEM TO BE SOLVED: To solve the problem that it is impossible to correctly set mold clamping force suitable for the shape (size) of a molding for a mold of the same thickness, improper force is applied to components such as the cutting blade and spindle of the mold, the durability of these is lowered, erroneous burr cutting by the cutting blade of the mold, the falling and torsion of the mold, etc., occur, and it is difficult to mold a molding of good quality. SOLUTION: An apparatus is constituted so that for the mold 1 of the same thickness, by an opening/closing driving apparatus 32, before the end of the clamping of the mold 1, a toggle mechanism 9 is set to obtain a prescribed quantity L of pushing, and the effective length of the toggle mechanism 9 is changed by driving an adjusting member 41. A detection means 48 detects the occurrence of prescribed pushing force, and by making the toggle mechanism 9 with the mold closed take a prescribed folding attitude, the mold clamping force at the end of mold closure is set by a plurality of pushing quantities L.
