摘要： An apparatus for precisely and adequately filling each of upper and lower flask bodies with molding sand equipped with upper and lower compressed air jet mechanisms (which fluidize molding sand at side and lower parts in a substantially horizontal part of each of upper and lower blow heads) and upper and lower guide members (which guide molding sand so as to disperse it toward the entire area of end openings of the blow heads after the molding sand in each blow head has first been focused on the blow head's central part) projectingly provided in the upper and lower blow heads, and a blow head for use in such an apparatus. Thus, the molding sand in the upper and lower blow heads is almost entirely fluidized by jetting compressed air from the upper and lower jet mechanisms when molding sand is blow-squeezed into upper and lower flask bodies. As a result, the molding sand is blown into the upper and lower flask bodies while it is dispersed toward the entire area of the end openings of the upper and lower blow heads.
