A mould-closing arrangement for injection moulding machines has a base 1 with a fixed mould mounting platen 3 and movable mould mounting platen 2 moved by cylinder/piston units 4. The units 4 are external of the platens 2, 3 and diagonally opposite one another and each is mounted at the cylinder end upon the platen 3 by a pivot joint 6 in a carrier 15 rigidly connected to the platen 3. The free end of the piston rod 7 of each unit 4 is pivotally connected to a respective upright carrier 9 which is connected to one end of each of two vertically aligned force transmitting columns 5 which pass through the movable platen 2 and are operatively connected thereto. The other ends of the four columns 5 respectively co- operate, after the traverse of the movable platen 2, with closing cylinders 16, mounted on the fixed platen 3, for producing mould closing and clamping force. A device 14, 23, 27 is arranged on the movable platen 2 for adjusting the mould part installation spacing to accommodate moulds of different sizes. For controlling the mould- closing arrangement, signal receivers 10 are mounted on one of the carriers 9 and co-operate with a signal carrier 11 mounted on a support 12 fixed in the base frame 12. <IMAGE> |
