摘要： A method of finishing like castings wherein the exact dimensions of the casting (13) are not known requires the steps of traversing the casting along a fixed path impinging excess material (14) on a reduction apparatus such as grinder at a fixed location such that a defined witness (20) is produced on the excess material (14), measuring the difference from the witness (20) to the casting parent material and adjusting the fixed path to remove the excess material (14) to within a specified tolerance.

摘要： An offset conveyor system (10) utilizes a lower conveying section (11) positioned adjacent a pouring station (61) where molten metal is poured into weighted and jacketed sand molds. Molds (21) are transported on carriers (16) along the lower section (11) from a mold loading station (31) to a weight and jacket placement station (41) to the pouring station (61). After pouring, the carrier (16) with jacketed mold (21) is moved up an incline to an upper conveying section (13) parallel the lower section (11) and may overlap the lower section (11) partially. Molds (21) are transported in an opposite linear direction relative to the lower section (11) to the weight and jacket removal station (41) and to a mold dump station, where the sand mold (21) and casting are removed from the conveyor (13). The carrier is returned to the lower conveyor section (11) to receive another mold. The weight and jacket (22) removed from the upper section (13) is placed on a mold (21) on the lower section (11), therefore only a minimum number of weights and jackets (22) are used. The mold carriers (16) may be dimensioned to carry sand molds (21) in side by side relation thus, castings may circulate more than one circuit on the upper and lower conveyors (11, 13) to permit additional cooling and solidification if necessary or multiple pourings may be accomplished.

摘要： An apparatus for promoting uniform sand distribution into a mold flask (34) in a foundry process including a fixed distribution plate (31) mounted subjacent a hopper (32) and a slide distribution plate (36) slidably mounted subjacent the fixed plate (31), wherein the slide plate (36) has a repeating series of apertures (37) therethrough with each aperture series (37) corresponding to one aperture (33) through the fixed plate (31). Each aperture series (37) comprises a plurality of apertures (37) having different diameters. Accordingly, the slide plate (36) is movable between a plurality of positions such that as different flow rates are desired, the appropriate sized apertures (37) through the slide plate (36) are fully aligned with the apertures (33) through the fixed plate. Alternately, a fixed plate is mounted subjacent the hopper with first and seconde slide plates underneath which can be aligned to form a plurality of zigzag channels through which sand can flow at a reduced flow rate.

摘要： A pouring conveyor (11) in the form of a continuous loop receives sand molds (M, M') on pallets (12) or other mold carriers and conveys the empty molds to a pouring station (80) wherein molten material is deposited therein to form castings. Each mold (M, M') is provided with a supportive weight and jacket (14) before pouring. Thereafter, the molds (M, M') with the weight and jacket (14) surrounding them, pass through a primary cooling line, at the end of which molds and weight and jacket are separated in a jacket transfer station. The weighted jacket is removed and transferred to an on-coming freshly made mold while the castings pass through a secondary cooling zone for further cooling and subsequently discharged said conveyor (11). The process allows for a substantially smaller number of weight jacket combinations and floor space than previously known molding processes.
