Abstract

1324611 Injection mould closing devices ODESSKY ZAVOD PRESSOV 12 Jan 1971 1412/71 Heading B5A An injection mould 3, 4 is closed at high speed by an hydraulic piston 6 and cylinder B acting through toggle mechanism A, final clamping pressure being applied by an hydraulic piston 5 and cylinder D, the cylinder B forming the piston-rod of the piston 5. The piston spaces II and III of the two hydraulic cylinders D and B are connected to each other but the piston 5 does not move until the piston 6 has completed its movement owing to pressure in space I.
