Next, the operation of the apparatus configured as described above will be described. First, the squeeze cylinder (1) is extended to raise the model plate (3) and the flask (4) through the surface plate (2). At the same time, the casting frame (4) is brought into contact with the filling frame (5),
Subsequently, the molding sand (S) is put into the casting frame (4) and the filling frame (5). Then, a cover (not shown) is brought into airtight contact with the fill frame (5) to blow compressed air onto the upper surface of the molding sand (S) to flow through the molding sand (S), and then the vent plug of the model plate (3). (Not shown) to pre-compress the foundry sand (S), and then the extension operation of the cylinder (16) causes the squeeze board (9) to pass through the traveling frame (7).
Etc. are transferred to a position directly above the fill frame (5) (see the drawing).
Next, the blower (14) is driven in reverse to suction and decompress the inside of the recess (9b) of the model part (9a), the cylinder (8) is extended to lower the squeeze board (9), and the molding sand (S ) With a squeeze board (9). As a result, the entire molding sand (S) is compressed, and at the same time, the molding sand (S) is further compressed while partly being sucked up into the recess (9b). After the molding sand (S) is compressed, the blower (S 1
4) Drives forward rotation of compressed air to vent plug (10) (1
While ejecting from (0), the squeeze board (9) is lifted by the contraction operation of the cylinder (8) to perform mold release. As a result, as shown in FIG. 2, the hot water retaining cup (C) is integrally formed with the green mold so as to project from the upper surface of the casting frame (4). In addition, when the thickness (T) of the bank of the hot water cup and the height (H) of the hot water cup in FIG. 2 have a relationship of H / T ≧ 1.0, the sprue cup has hardness and strength. It will be good.
