    摘要: In a mould forming machine comprising a moulding chamber, a movable squeeze plate and a pattern, the filling of selected parts of the pattern with compressible mould material is improved by applying vacuum to said selected parts. By applying the vacuum separately to different parts of the pattern at different periods of time during the filling step, the vacuum application can be applied during shorter periods only when needed, thereby reducing the drying out of the mould material and reducing the amounts of air to be removed by the vacuum system.

    摘要: A molding method is disclosed to fill a mold space in a pattern box with molding sand. By this method are carried out at least once the steps of (a) measuring and feeding a first amount of all the molding sand necessary to produce a mold in the mold space, the first amount being one of at least two parts divided from the total molding sand, (b) introducing air flows into the mold space at the air-pressure rising rate of 30 - to 500 kg/cm 2 /sec, (c) feeding the remaining parts of the molding sand into the mold space; and (d) introducing air flows into the mold space at the air-pressure rising rate of 30 - to 500 kg/cm 2 /sec.

    摘要: A device for filling shooting heads (1) with moulding materials (2) has a reservoir (3) for moulding material (2), an outlet member (4) for discharging moulding material (2) into the shooting head (1) and a filling member (6) with a closure member (5) for closing the outlet member (4). The filling member (6) is vertically movable on a machine frame (7) to allow the outlet member (4) to be immersed into the shooting head (1) to be filled. In order to fill the filling member (6) with moulding material in an exactly predeterminable and reproducible manner and to accurately determine the filling level of the filling member (6), a weighing device (8) arranged between the filling member (6) and the machine frame (7) determines the weight of the filling member (6).

    摘要: There is provided at the mouth of a sand-­supplying hopper (8) and under a hatch (6) metering supply of such sand, a motor (9) mounted on a support (10) and with a plate (15) to protect it from sand discharges, driving a series of lower vanes (12) that spread out and level the sand within the compacting chamber (4). The discharge valve is placed annularly outside the hopper and is assisted by an annular stopper (26), that has a dihedral front for closing the likewise annular aperture (18) and that plays within a housing (25) of a support ring (22).
