1. A horizontal mold clamping mechanism comprising: a base; a rail disposed on the base; a slider fitted with the rail; a pedestal placed on the slider, the pedestal being provided with a sub-rail and a sub-slider fitted with and guided by the sub-rail; a fixed platen secured to the base for supporting a fixed mold; a mold clamping cylinder secured to the pedestal and horizontally movably supported on the base, the mold clamping cylinder being laid parallel to the fixed platen and having a piston rod extending toward the fixed mold; a mold opening/closing actuator for moving the mold clamping cylinder, the mold opening/closing actuator being connected to the pedestal; a movable platen secured to the sub-slider and disposed between the fixed platen and the mold clamping cylinder, the movable platen being connected to the piston rod and horizontally movably supported on the base for supporting a movable mold; a tie-bar extending horizontally from the fixed platen and passing through the movable platen and the mold clamping cylinder; and a first linking mechanism for selectively linking the mold clamping cylinder to the tie-bar; wherein the movable platen is provided with a through-hole having a hole diameter greater than an outer diameter of the tie-bar to provide a clearance for preventing slide-contact between the tie-bar and an inner peripheral surface of the through-hole.
