Abstract
A mold clamping device for an automatic mold opening and closing machine is used to clamp or release an upper mold which has a pair of wings. The mold clamping device is provided with two pressure cylinder units located at two lateral surfaces of the mold mounting unit, two pivot units pivoted to the two pressure cylinder units, respectively, and two clamping members pivotally disposed between the pressure cylinder units and the pivot units. When the first piston is in the first position, the clamping member will be rotated an angle to disengage the inner portion from the wing of the upper mold, and when in the second position, the piston will drive the clamping member to rotate an angle in a reverse direction, so that the wing of the upper mold is clamped between the inner portion and the bottom surface of the mold mounting unit.
