1,140,118. Injection moulding machines. MASCHINENFABRIK UND GIESSEREI NETSTAL A.G. 19 Aug., 1966 [19 Aug., 1965], No. 37334/66. Heading B5A. A mould member 4 is moved to a substantially closed position by pistons 13 and cylinders 14 and then, if there is no obstruction between the mould member 4 and a fixed mould member 2, an increased closing pressure is applied by a piston 6 and cylinder 20 through toggle mechanism 5. In operation, magnetic valves 10, 16 are first activated and in turn actuate control valves 9, 15 so that pressure liquid in the hydraulic system only acts on pistons 13. At this stage liquid is transferred from space 8a through valve 9 to space 8b. When the mould members come together a contact 17 is closed by a cam 18 and disconnects a magnetic valve 10, thereby allowing liquid to pass through valve 9 to cylinder 20. If there is an extraneous object between the mould members a time delay relay causes an alarm to operate.
