    Abstract: A clamping apparatus for a tiebarless injection moulding machine is arranged to absorb all of the clamping forces. The machine has a machine frame supporting a fixed platen and a movable platen which carry mould halves. The movable platen is slidable along linear guide rails as is a force transmission member or second movable platen incorporated in a drive for the movable platen. The drive comprises a hydraulic cylinder and piston unit. A clamping structure has two, parallel clamping frames, each of which is substantially U-shaped so that upstanding clamping arms are defined in each clamping frame. Each clamping arm terminates in a respective force transmission part which has a curved surface and which abuts a respective one of the fixed platen and the second movable platen. When a moulding operation is undertaken, the mould halves carried by the fixed and movable platens are brought into clamping contact. The fixed platen remains contacted by force transmitting parts of the clamping frames and the second movable platen also contacts the force transmitting parts of the clamping frames. When full clamping force is applied to the mould halves, the curved surfaces of the parts receive the reaction forces and transmit those forces to the clamping frames which become deformed due to the absorption of the clamping forces. The absorption of the forces by the clamping frames, protects the machine frame against any deformation by the clamping forces.

    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.

    Abstract: A system is disclosed for neutralizing the punching reaction forces in an open frame punch press in which inclined primary links mounted on the upper and lower frame members are stressed by linkage actuators during punching so as to counteract the punching reaction force. In one embodiment, a charging cylinder mounted to be acted on by the punch ram actuator generates hydraulic pressure used to operate linkage actuators. In that embodiment, the primary links are combined with secondary links to form toggle linkages to enable mechanical force multiplication of the force applied by the linkage actuators. In another embodiment the primary links converge and are pivotally connected at their rear ends to each other and a single secondary link, with a single cylinder at the forward end of one of the primary links, placing the primary links in tension during punching operations to neutralize the punching reaction forces acting on the press frame.

    Abstract: A tie bar tensioning system that allows a bending machine operator to removably couple an upper end of a bend die post of the bending machine to a base of the bending machine via a tie bar, and to lock the tie bar in a tensioned position. The tensioning system includes a stationary member and a rotatable member, each with aligned tie bar passages for receiving the one end of the tie bar. Both the stationary member and the rotatable member include respective engagement surfaces, with the rotatable member engagement surface being rotatable relative to the stationary member engagement surface between a released position and a tensioned position whereat the rotatable member is selectively lockable. The rotation of the rotatable member with the stationary engagement surface in engagement with the stationary engagement surface longitudinally displacing the rotatable member relative to the stationary member.
