Abstract

Mould closing, clamping and opening means for the split mould of a pressure moulding machine comprises a pair of elongated arms (15) each pivotally attached to the moving platen (12) of the machine at one end and free at the other end, and extending lengthwise between the moving platen and a hydraulic rear clamping platen (13). During a mould operation the free ends of the arms engage the rear clamping platen so as to act as struts between the rear clamping platen and the moving platen during a mould clamping operation, but during a mould opening operation the arms are swung by an hydraulic cylinder to a position in which they register with openings (25), (26) in the rear clamping platen so that the arms may pass rearwardly through the openings as the mould opens. <IMAGE>
