Mold clamping apparatus
09731442 · 2017-08-15 · ·

A mold clamping apparatus includes a mold clamping cylinder. The mold clamping cylinder has, in a region thereof located below left and right lower tie bars and above left and right sliders, a left grooved portion opened leftward and elongated horizontally, a right grooved portion opened rightward and elongated horizontally, and a leg portion formed between the left and right grooved portions. The leg portion and the left and right grooved portions together form a constricted part.

Mold clamping apparatus
09724862 · 2017-08-08 · ·

A mold clamping apparatus includes a fixed platen, a mold clamping cylinder, a movable platen moved by the mold clamping cylinder toward the fixed platen, and a mold opening/closing actuator for moving the movable platen or the mold clamping cylinder. The mold clamping apparatus further includes a mold thickness adjustment cylinder provided between the mold clamping cylinder and the movable platen, the mold thickness adjustment cylinder being configured to generate an axial force larger than an axial force in an expanding direction of the mold opening/closing actuator and smaller than an axial force in a contracting direction of the mold clamping cylinder.
