Abstract: 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).

Abstract: A method for producing casting cores and/or casting molds is provided. The core shooter and/or molding machine (1) has at least one shooting unit (2) including a shooting head (4), filled with a material to be shaped (50), especially a mixture of core or molding sand with a binder. The mixture is shot into a molding tool (100) by supplying pressurized air through a shooting board (5) which includes at least one shooting opening (6). At least one moveable mixing tool (7) is disposed in the shooting head (4) and is used to mechanically loosen the material to be shaped (50) present in the shooting unit (2) before, during or after shooting.

Abstract: The invention relates to a device (1) for mechanically rough and or finish machining workpieces, especially flash trimming cast parts. The device has at least one multiaxial robot (2) or manipulator for this purpose. The robot or manipulator supports at least one tool for machining workpiece(s). The device (1) is also provided with a clamping device (5) for holding the workpiece or cast part to be machined. The provision of a magazine (6) for multiple exchangeable tools is also advantageous. The process of changing tools on the robot (2) is preferably program-controllable.

Abstract: Apparatus for transferring metered quantities of a flowable bonding agent from a tank into a mixer of a sand core making machine has an upright tubular vessel into which the bonding agent is drawn from the tank by a suction pump and a pressure pump which transfers the accumulated bonding agent from the vessel into the mixer. The vessel contains a float which cooperates with sensors serving to generate signals for actuation or deactivation of the pumps and/or valves in the conduits connecting the vessel with the tank, mixer and the pumps. The bonding agent is kept out of contact with the pumps and out of contact with the valves in the conduits connecting the vessel with the pumps.

Abstract: A core making machine wherein a selected blow plate is attracted to the blow head by suction and/or by one or more magnets so that the connection between the blow head and the plate can be terminated or established practically instantaneously without the utilization of screws, bolts and nuts, clamps, hooks or other conventional fasteners.

Abstract: Apparatus for making molding sand has one or more housings defining upright cylindrical chambers and being movable with reference to a plate-like support to and from positions of register with an aperture in the support. Each chamber is normally closed at its upper end by a closure which has outlets for sand and one or more binder materials (such as clayey matter, pulverulent iron oxide, pulverized wood and/or others), and a rotary propeller is movable axially in each chamber to mix the ingredients in the circumferential direction as well as axially of the respective chamber.
