成形機の型締制御装置。 Used in a mold clamping device that opens and closes a mold for molding and cooling molten resin injected from an injection device, a hydraulic cylinder, a piston slidably provided in the hydraulic cylinder, and the piston. In a mold clamping control device that controls a hydraulic drive circuit according to a predetermined setting value, the drive shaft body is connected to one surface, extends in a predetermined direction, and applies a driving force to the mold. When driving in a direction opposite to the predetermined direction, the set value is output as is, and when driving the drive shaft body in the predetermined direction, the ratio of the surface area between one side and the other side of the piston is output. 1. A mold clamping control device for an injection molding machine, comprising: digital signal automatic correction means for correcting and outputting the set value according to the set value.
