Abstract

A mold clamping device for applying mold clamping force by using an electromagnet has a mold clamping force detection section for detecting the mold clamping force, a supply current calculation section for calculating the value of an electric current supplied to the electromagnet, the calculation being based on an error between a target mold clamping force and the value of the mold clamping force detected by the mold clamping force detection section, and a limit section for suppressing the electric current value calculated by the supply current calculation section to a predetermined pattern. The mold clamping device can appropriately control mold clamping force obtained by the electromagnet.
