Abstract

1331828 Mould closing devices MANNESMANN-MEER AG 14 Dec 1971 [15 Dec 1970] 57912/71 Heading B5A A mould closing device comprises a mould carrier plate 5 slidably mounted on columns 4 between a fixed mould carrier plate 2 and a fixed cross beam 3, the mould carrier plate 5 being in the form of a closed pressure cylinder divided by a piston 7 into two pressure chambers 18, 19, and the mean position of the piston 7 being adjustable, the piston 7 having a piston rod 8 which can be locked rigidly in the cross beam 3 by means of slides 10, and an hydraulic transfer cylinder 12 connected to the mould carrier plate, the cylinder 12 containing a piston 13 having a piston rod 14 on each side. One of the piston rods 14 is slidably mounted on the fixed mould carrier while the other is fixedly mounted on the cross beam 3 or vice versa. Operation is controlled through valves 16, 17 connected to a pump 15, additional valves (not shown) being provided to control the slides 10. Initial closing is effected by means of cylinder 12 and piston 13 and final clamping by admitting pressure fluid to chamber 19.
