摘要： A pouring ladle (12) includes a horizontal chamber (22) having an inlet (24) at one end thereof for admitting molten metal into the chamber (22) and a bottom-poured nozzle (28) at an opposite end for discharging the metal into an underlying mold (30). A coreless induction heater (56) surrounds the chamber (22) for heating metal as it flows from the inlet (24) to the outlet nozzle (28). The induction heater (56) may be operated simultaneously with the pouring of metal and be used to pour treated ductile iron without plugging the inductor (56).

摘要： A thin wall inner is positioned within the circular bowl of a sand muller to overlay the interior mulling surface upon which foundry sand is placed and is mulled by a plow blade that rotates within the bowl over its mulling surface. The bowl surface is annular and ring-like in shape. The liner is formed of a number of similar segments which are arranged together in edge to edge relationship to form an annular, ring-like cover over the bowl surface. The liner segments are secured to the bowl by bolts which extend through aligned holes in the segments and in the bowl. Most of the outer surface of the liner is spaced a short distance from the bowl surface by means of thin pads formed on the outer surface of the liner, around the area of the bolt holes. The pads contact the bowl surface, to provide a space between the remainder of the liner and the bowl surface. This space is filled with a grout-like material for bonding the liner to the bowl and for shock absorbing and load distribution. The liner is formed of a hard material which is much more wear resistant than the bowl to permit extended use of a worn bowl or to extend the life of an unworn bowl.

摘要： Metals castings, having a number of internal passageways which open at different surface portions of the castings, are mounted upon a horizontally axised wheel-like frame. The frame is intermittently rotated and momentarily stopped so that castings are rotated at times and stationary at times. During the times that the castings are stationary, they are simultaneously subjected to either an externally applied vibration or to a momentary, several millisecond long, high pressure burst of air through their respective passageways. The alternating vibrations and momentary bursts of air loosen and remove the sand and other casting debris contained within the passageways. Additionally, the changing angularity of the castings, due to the rotation, coupled with the vibrations and bursts of air, dislodge such sand and debris from the walls and, also, downwardly out of the passageways.

摘要： A machine for repeatedly impacting metal castings in order to clean the castings of debris, such as sand, is formed of a wheel-like frame which is rotatably mounted upon a horizontal axle. The frame is divided into four equally spaced apart compartments which provide two pair of opposed compartments. The radially innermost wall of each compartment is formed of a metal plate arranged parallel to the axle so that the plate of the uppermost compartment is horizontal and forms a floor-like support for the casting which is then located in that compartment. Each plate is loosely supported upon springs and has an exposed end portion that extends transversely outwardly of the frame. An impact hammer is arranged to repeatedly apply blows that are directed radially towards the axle against the exposed end portion of the uppermost plate for vibrating the plate and for transmitting the forces of the blows to the casting for loosening debris clinging thereto. An endwise slidable bar extends through the plates of each pair of compartments so that a casting that is moved horizontally into a compartment physically pushes its bar endwise to push the casting in the opposed compartment horizontally outwardly of the frame for horizontally loading and unloading the castings.

摘要： The invention relates to a system and method for the automated spin-casting production of molded articles. The system includes a casting turntable and a processing turntable which are rotatively mounted, immediately adjacent to one another. The casting turntable has several spin modules mounted thereon for rotatively supporting mold assemblies. Casting preparation and pouring mechanisms are mounted around the periphery of the casting turntable. The turntable indexes the mold assemblies and positions the assemblies for preparation, pouring and solidification of the cast products. The processing turntable receives the mold assemblies and solidified castings from the casting turntable. Multiple processing stations are mounted around the periphery of the processing table for the removal of the castings from the mold assemblies and preparation of the mold assemblies for additional casting operations. The mold assemblies are returned to the casting table from the processing table for additional casting processes.

摘要： A blow head or gassing head of an automatic core machine, which produces sand casting cores in a core box is formed of a downwardly opening box-like frame having a bottom closure plate. The heads may be alternatively used to respectively deposit a sand and binder material or to flow gas into a sand-filled core box cavity positioned beneath the head. The closure plates are provided with openings through which either the sand-binder material may drop from the blow head frame into the core box cavity or through which gas may flow from the gassing head frame into the cavity. The plate is loosely positioned beneath the frame and is clamped tightly upwardly against the bottom peripheral edge of the head by a spaced pair of elongated, rigid rails which engage and support the opposite side edges of the plate. A rail holding a clamping mechanism selectively moves the rails upwardly for clamping the plate against the frame and downwardly to free the plate relative to the frame. The rails are lowered when the openings in the plates become partially or fully obstructed or when different opening patterns are required so that the plate may be slid horizontally from beneath the frame and a substitute plate may be slid upon the rails beneath the frame and then clamped upwardly against the frame edges.

摘要： A machine for automatically blowing debris, such as sand, out of cavities within engine block and similar type castings which have side openings connected to end openings to form internal cavities. The machine has a ferris-wheel-like frame arranged to rotate around a horizontal axis. The frame is divided into a number of horizontally opening compartments, each arranged to receive and hold a single casting. A dirty casting is loaded, horizontally endwise, while the frame is momentarily stationary, into the compartment which is then located in the lowermost position. Thereafter, the frame is rotated until the next compartment is located in the lowermost position, at which point the rotation is stopped so that the clean casting in the now lowermost compartment is horizontally removed endwise and is replaced with the next dirty casting. The stop, followed by the rotation, sequence is repeated so that each casting, within each compartment, is indexably rotated around the axis. During the time that the frame and castings are rotating, high pressure air blowing nozzles, which are located in each compartment, automatically swing into the openings located on the sides of the castings to blow the debris contained therein. The high pressure air blower nozzles swing out of the side openings during the time that the frame rotation is momentarily stopped during the unloading the loading of the castings in the lowermost compartment. During that time low pressure air nozzles, which are fixedly positioned along side of each compartment, except for the lowermost one, direct low pressure air into the openings in the ends of the castings. Thus, the cavities within the castings are repeatedly subjected to alternating high pressure air blasts in one direction and low pressure air blasts in the opposite direction for loosening and blowing sand and the like debris out of the casting cavities.

摘要： A casting apparatus for pouring molten metal into molds comprises a vessel having a molten metal-receiving chamber generally extending between a filling end and a pouring end. The vessel includes a nozzle disposed in a bottom surface of the chamber proximate to the pouring end. A stopper cooperates with the nozzle to control a downward gravity flow of molten metal through the nozzle. A first support pivotably supports the vessel to provide a horizontal tilt axis substantially coincident with the nozzle. A second support is connected to the vessel at a point away from the tilt axis and has a drive for controlling a pivot position of the vessel. A tilt angle controller detects a level of molten metal within the chamber and engages the drive to maintain the level at a predetermined level.
