Abstract
753,498. Injection - moulding machines. HUPFIELD, B. J. D. Nov. 15, 1954 [Aug. 13, 1953], No. 22355/53. Class 87(2) The heating cylinder 10 reciprocates telescopically, over a fixed ram 16, between the positions shown in Figs. 1 and 3. As it moves rightward, away from the mould 34, 35, to the Fig. 3 position, heated moulding material is pushed from the rear of the cylinder leftward, past a one-way valve 13, into a chamber 12. Within the chamber 12 is slidably disposed a nozzle 22. When the cylinder moves leftward from the Fig. 3 position to the Fig. 1 position the nozzle seats in the mould injection aperture 36, and on further leftward movement the material in chamber 12, being unable to get past valve 13, is forced through passages 25, 26 in the nozzle into the mould. When the cylinder retracts to the right, fresh moulding material falls thereinto from hopper 37 via aperture 21. The cylinder is reciprocated by hydraulic piston 28, and is secured to platens 14 which slide on rods 15. The mould section 34 is secured to a platen 32 which, with platen 31 to which it is secured by the rods 15, forms a frame which reciprocates on bars 33 to open and close the mould, this frame being moved by a hydraulic piston 29 which forms the cylinder for piston 28.
