Abstract
A mold clamping apparatus of the type including a mold opening/closing actuator and a mold clamping cylinder, wherein rails for guiding a movable platen are disposed on a base, and the mold clamping cylinder has a left leg and a right leg each disposed between one pair of left and right rails of the rails. The rails provided for guiding the movable platen is used also as a side guide for the mold clamping cylinder. This arrangement can obviate the need for a separate guide member.
Claims4
A mold clamping apparatus comprising:
- a base;
- a fixed platen fixedly mounted on the base and supporting a fixed mold;
- a mold clamping cylinder disposed parallel to the fixed platen and horizontally movably supported on the base, the mold clamping cylinder having a piston rod extending toward the fixed mold;
- a movable platen disposed between the fixed platen and the mold clamping cylinder and connected to the piston rod in such a manner as to be horizontally movably supported, the movable platen supporting a movable mold;
- tie bars extending horizontally from the fixed platen and penetrating the movable platen and the mold clamping cylinder;
- a first connecting mechanism arbitrarily connecting the mold clamping cylinder to the tie bars;
- a mold opening/closing actuator that connects the fixed platen or the base and the movable platen;
- and
- rails laid on the base and horizontally movably supporting the movable platen,
- wherein the rails comprise a long-length member that supports the movable platen and serves as a side guide for the mold clamping cylinder.
