[0048] figure 1 It is a schematic diagram which shows the structure of the cast iron casting manufacturing facility of 1st Embodiment.
[0049] A cast iron casting manufacturing facility 1 is a facility for producing cast iron castings using the V process, and has: a casting mold 2 using molding sand not containing a binder; a casting mold platform 3; a frame transfer device 4; a fixed suction device 5; and a movable suction device 6. In addition, the casting mold 2 is a casting mold formed of molding sand in a molding frame. here, figure 1 It shows the states of the fixed suction device 5 and the movable suction device 6 immediately before the mold 2 moves. When the casting mold 2 stops, each casting mold 2 is sucked by the fixed suction device 5 to decompress the inside of the casting mold 2. When the casting mold 2 moves, the fixed suction device 5 breaks away. Suction is performed to decompress the inside of the mold 2 . Thereafter, the movable suction device 6 follow...

[0056] The second embodiment relates to the structure around the mold 2 of the cast iron casting manufacturing facility 1 of the first embodiment. A second embodiment will be described with reference to the drawings. In the structure of the manufacturing facility of the cast iron casting of this embodiment, the part which differs from 1st Embodiment is demonstrated. The other parts are the same as those of the first embodiment, so the above description is referred to, and the description thereof is omitted here.
[0057] The manufacturing facility 1 of cast iron castings has a casting mold 2 , a casting mold platform 3 , a frame transfer device 4 , a fixed suction device 5 , and a movable suction device 6 . Figure 4 It is a schematic cross-sectional view around the mold 2 of the second embodiment. Figure 4 Indicates a casting mold of the V process, which is composed of a casting mold 2 using molding sand 9 without a binder, a fixed suction device 5, a temperature sensor 10...

[0062] The third embodiment is the same as the second embodiment, and relates to the structure around the mold 2 of the cast iron casting manufacturing facility 1 of the first embodiment. A third embodiment will be described with reference to the drawings. In the structure of the manufacturing facility of the cast iron casting of this embodiment, the part which differs from 2nd Embodiment is demonstrated. The other parts are the same as those of the second embodiment, so the above description is referred to, and the description thereof is omitted here.
[0063] The manufacturing facility 1 of cast iron castings has a casting mold 2 , a casting mold platform 3 , a frame transfer device 4 , a fixed suction device 5 , and a movable suction device 6 . Figure 5 It is a schematic cross-sectional view around the mold 2 of the third embodiment. Figure 5 Represents a V-process casting mold, which is composed of a casting mold 2 using a binder-free molding sand 9, a temperature sens...
