<p>This machine of this invention is for precisely and adequately filling each of upper and lower flask bodies with molding sand, and is equipped with second upper and lower compressed air jet mechanisms, which fluidize molding sand at the side and lower parts in the substantially horizontal part of upper and lower blow heads (4,5). These mechanisms are respectively provided in the upper and lower blow heads, and upper and lower guide members (4a,5a), which guide molding sand so as to disperse it toward the entire area of end openings after the molding sand in the blow heads is first focused on its central part, are projectingly provided in the upper and lower blow heads (4,5). Thus, the molding sand in the upper and lower blow heads (4,5) is almost all fluidized by jetting compressed air from the second upper and lower jet mechanisms (16-19) when molding sand is blow-squeezed into the upper and lower flask bodies (2,3). As a result, molding sand is blown into the upper and lower flask bodies (2,3) while it is dispersed toward the entire area of the end openings of the upper and lower blow heads (4,5). <IMAGE></p> |
