Abstract
An apparatus for closing a mold having a pair of mold halves has a housing, a fixed support block on the housing carrying one of the mold halves, an abutment block on the housing, and a support block movable on the housing between the fixed support block and abutment block in a direction toward and away from the fixed block and carrying the other of the mold halves. A frame has at least one plate lying in a vertical plane generally parallel to the axis and formed with a pair of stiff upwardly extending upper arms, a pair of stiff downwardly extending lower arms below the respective upper arms, and an elastically deformable web extending in the direction between the upper arms and the lower arms. Anchors, e.g. bolts, fix one of the upper arms to the fixed support block and the other of the upper arms to the abutment block. A main actuator effective in the direction is braced between the movable support block and the abutment block and can expand to press the other mold half in the direction against the one mold half with elastic deformation of the web and to spread the upper arms. A secondary actuator braced between the lower arms can be expanded to push the lower arms apart in the direction and thereby urge the upper arms together.
