Casting mold device for iron alloy processing

The utility model relates to the technical field of iron alloy processing, and discloses a casting mould device for iron alloy processing, which comprises a bottom plate and a top plate, the top plate is positioned above the bottom plate, two support plates are arranged between the bottom plate and the top plate, and a mould body is arranged at the top of the top plate. A mounting plate located between the two supporting plates is arranged at the top of the bottom plate. According to the casting mold device for iron alloy machining, by arranging the driving assembly, a driving motor is started to drive a left side driving rod to rotate through a second belt, so that the left side driving rod drives the other three driving rods to rotate through a first belt, and the driving rods drive cams to rotate; the pushing roller drives the sliding block to move upwards through the connecting base, and the sliding block drives the ejection block to move upwards through the ejection rod, so that iron alloy formed in the
