Abstract

760,189. Casting-machines. RI-RI WERKE AKT.-GES. Sept. 24, 1954 [Sept. 26, 1953], No. 27619/54. Class 83 (1). [Also in Group V] A die-casting machine comprises an hydraulically-operated device 2 for controlling a vertically-movable die 25, a hydraulically-operated device 10 for injecting the molten metal or plastic material, and a nozzle 15 extended by a longitudinally movable runner-distributing piece 23. The upper die 26 is bolted to a head 7 which can be released by bolts 9 to be swung about a central pivot 8. The lower die is clamped in operative position by pistons 3. In operation, when the pressure of the clamping-pistons 3 has reached a predetermined pressure, the gate 23 and the nozzle 15 are moved forwardly by hydraulic means 22, 20. The injection-plunger 12 is then moved sharply through the chamber 13 to force the charge into a heating chamber 19 and the previously-heated material into the die. During its movements, the plunger 12 opens and closes a shutter 31 to allow a further charge to enter the chamber 13 from a hopper 16 by way of a chamber 18. When casting sliding-clasp fastener-elements on to stringers, new stringers may be laid in their correct positions by a slide moving over the lower die 1 when in its retracted position.
