摘要： A mold clamping device for an injection molding machine wherein a movable table which supports a movable mold is moved in directions approaching and moving away from a fixed table which supports a fixed mold to thereby bring the molds into open and closed states, and wherein mold clamping is effected in a closed state of the molds by mold clamping cylinders. The mold clamping device includes tie rods for guiding the movement of the movable table, the tie rods projecting upward from the fixed table and being each provided with an engaging groove such as threads or the like formed on the outer peripheral surface of its portion projecting from the movable table to the side opposite to the fixed table in the closed state of the molds; and split mold-like locking members capable of engaging with and disengaging from the tie rods each through each engaging groove in the closed state of the molds, the locking members being slidable in the axial direction of the tie rods. The mold clamping cylinders are disposed between the locking members and the movable table. Since the tie rods which receive the mold clamping reaction are so constructed as to also be employable as guide members for guiding the movement of the movable table, it is possible to attain a structural simplification and reduction in size in addition to advantage in terms of maintenance.
