Abstract

1,003,797. Injection moulding machines. M. M. DUNKEL, [trading as E. LEYBOLD'S NACHFOLGER]. May 1, 1963 [May 2, 1962], No. 17243/63. Heading B5A. An injection mould 4, 5 is enclosed by an evacuable jacket comprising at least two cooperating relatively movable parts 6, 7 provided with compressible sealing rings 8, 9 which project beyond the co-operating faces of the mould parts so as to permit vacuum-tight closure of the jacket 6, 7 and evacuation of the mould before the mould parts are closed to-. gether. A feed hopper for the material is also closed and evacuable (Fig. 1, not shown).
