Abstract (en)
[origin: US2008277089A1] To produce moulds or cores for foundry purposes from a mixture (M) of moulding material or sand and a binder, the mixture (M) is shot using a shooting unit ( 2 ) or from a shooting tube ( 3 ) and a shooting head ( 4 ) through at least one discharge opening ( 7 ) arranged on a shooting plate ( 5 ) into a moulding or core tool ( 8 ). The region of the discharge opening ( 7 ) is moistened and/or kept moist by a liquid between at least two shooting operations, where the liquid ( 15 ) used for moistening is atomized by at least one ultrasonic atomizer ( 16 ) to form an aerosol capable of suspension and is fed to the discharge opening ( 7 ) directly or indirectly, for example, via one or more lines ( 18, 23 ).
