Abstract

A mold clamping device having a linear motor and opened and closed by movement of movers of the linear motor relative to its stators. The mold clamping device has a first member where the stators are provided and a second member where the movers are placed so as to face the stators. The first member is connected to a fixed platen where a fixed mold is placed, and the second member is connected to a movable platen where a movable mold is placed. On the first member and the second member, there are arranged sets of the stators and movers such that, when the movable mold is advanced and receded relative to the fixed mold, attraction force acting between the stator and the mover of one of the sets and attraction force acting between the stator and the mover of another of the sets act substantially symmetrically. The construction reduces deformation of the members caused by magnetic force of the linear motor for driving opening and closing of the mold.
