Abstract
A mold clamping machine includes a stationary mount, a movable mount, a mold-clamping mechanism and a mold opening and-closing mechanism. The mold-clamping mechanism includes a cylindrical constraining mechanism and has a magnet mechanism built therein. By causing a current to flow or not flow, the constraining mechanism changes to an unconstrained state or to a constraining state. In the unconstrained state, the mold clamping mechanism is movable relative to and along a tie bar. In the constrained state, the mold clamping mechanism becomes unmovable relative to the tie bar. The magnet mechanism positions the mold-clamping mechanism at any desired arbitrary position along the tie bar.
