摘要： Used in a method of this invention is a die clamping unit, which comprises a tie bar movably attached to a stationary platen, a halfnut positioning servomotor which advances and retreats the tie bar, a halfnut which is provided on a movable platen and fixes the movable platen and the tie bar together by engaging the tie bar, an engaging mechanism which engages the halfnut with the tie bar, a hydraulic die clamping cylinder which presses the stationary platen and the movable platen, and a control device which controls the halfnut positioning servomotor and the hydraulic cylinder. The control device drives the halfnut positioning servomotor to remove a clearance between the halfnut and an engaging groove of the tie bar before a die clamping process carried out by the hydraulic cylinder.

摘要： A die clamping unit includes a stationary platen, a tie bar which is attached to the stationary platen, a movable platen which is movable forwards and backwards along the tie bar with respect to the stationary platen, a first servomotor which moves the movable platen away from the stationary platen in a core-back operation, a second servomotor which moves the movable platen forwards and backwards to perform die-opening and -closing, and a control device which drives the first servomotor to move the movable platen away from the stationary platen and which drives the second servomotor to apply a force to the movable platen in the direction toward the stationary platen in the core-back operation.
