    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.
