とする型締装置。 a fixed platen that holds a fixed mold; a movable platen that holds a movable mold; means for moving the movable platen forward and backward relative to the fixed platen; the movable platen approaches the fixed platen;
After the fixed mold and the movable mold are closed, the tie bar is fixed to the fixed platen or the movable platen and clamps the mold, and the tie bar is fixed to the movable platen or the fixed platen, and the tie bar is fixed to the movable platen or the movable platen, and In a mold clamping device that uses a half nut or a half ring that opens and closes in a direction substantially perpendicular to the tie bar, the coupling and fixing of is performed as a means for moving the movable platen forward and backward with respect to the fixed platen.
Using a ball screw driven by an electric motor, a mold clamping cylinder is installed as a means to generate mold release force.
There is a slight gap between the mold clamping ram inserted into the cylinder and the half nut when the half nut is closed, and the mold clamping ram and the half nut are locked so that they can come into contact and separate from each other so that they cannot move relative to each other back and forth. Means is provided, and the groove portions of the tie bar and the half nut are provided with parallel grooves that have a slight gap when the half nut is closed and prevent the tie bar and the half nut from moving relative to each other in the front and rear. mold clamping device.
