Abstract
913,532. Injection-moulding machines. TURNER MACHINERY Ltd. Nov. 23, 1960 [April 12, 1960], No. 13048/60. Class 87(2). Injection moulding apparatus comprises an intermittently rotatable carrier 9 supporting four moulds 32 and mounted on a tie bar 4 so as to be axially reciprocable towards a fixed plate 3 and an auxiliary plate 61 by a hydraulically operated toggle mechanism, an injection unit having a nozzle 57 and adapted to inject material into a mould 32 through apertures 58, 60 in said plates at a first station, and a magnetic device 66 to assist the mould opening at the ejection station. With the apparatus in the Fig. 6 position, the toggle link is straightened and the carrier 9 and moulds 32, comprising base plates 33, 40 and mould halves 37, 41, are advanced to close plate 61 against plate 3 and depress a switch 84 which energizes coils surrounding steel heads 75. Simultaneously retraction of the magnetic unit is initiated by piston/cylinder unit 73 and a plunger 62 is advanced in cylinder 63 and abuts against plunger 55 thus advancing a thrust collar 54 which forces port 35 of the mould through pins 56 away from port 34 and against the energized retracting magnetic unit. The collar 54 then moves ejector unit 49 into chamber 48 and pins 50, 51 force out the moulded article. The carriage 71 of the magnetic unit is then returned to close the mould halves and switch 85 operated to de-energize the magnets. Switch 86 is then operated and fluid forced into cylinders 77 advances pins 78 and assists in the separation of the heads 75 and mould half 35. In the embodiments of Fig. 10 (not shown) a threaded cap is moulded and removed by rotation of the former. The unit 66 may be swung away from plates 3, 61 to facilitate cleaning &c. and a screw 14 is provided to accommodate moulds of different size. Specification 908,298 is referred to.
