Abstract

A mold clamping device includes an electromagnet which drives a mold clamping operation and a mold open/close drive unit. The mold open/close drive unit is variably controlled before a mold clamping force is generated by the electromagnet. Thus, it is possible to provide a mold clamping device which can reduce affects of the mold open/close drive unit in a mold clamping process.
