Abstract

832,712. Compression-moulding machines. BRITISH INDUSTRIAL PLASTICS Ltd. April 23, 1958 [April 26, 1957], No. 13442/57. Class 87(2). A loading plate 6 having cavities 8 for moulding material is adapted to reciprocate into and out of the daylight of a press of the flat bed type having upper and lower moulds by a drive mechanism 7 to locate said material in the die cavities. The mechanism 7 comprises a pinion 14 with a lower fixed rack 25 and a movable rack 29 on each side of the plate 6, the upper portion of the racks 29 being rigidly attached to the underside of the plate 6. The pinions 14 are freely pivoted on the ends of an axle 15, the centre of which is connected to the piston rod 17 of an hydraulic jack 19, and when said jack is operated rack 29 moves at twice the speed and for twice the distance traversed by the pinion centre. The mechanism 7, the plate 6, and the jack 19 are mounted on a supporting carriage 24 to which guide rods 39 are rotatably connected, and sections 53 of these rods are screw threaded in fixed nuts 54 so that the carriage and hence the plate 6 may be raised or lowered with respect to the press.
