The invention discloses a
rapid casting mold cooling method. The method comprises the following steps of production technology preparing, material preparing, sand making, modeling, drawing, mould assembling mold
casting, melting, pouring cooling and shaking out after curing. According to the
rapid casting mold cooling method, ventilation channels are manufactured in the
casting modeling process,
compressed air is blown in during pouring to conduct manual strengthened cooling, the
casting cooling speed is increased, and a very good effect is achieved for relieving the sand mold
heat effect; defects of a casting due to
molding sand heating can be reduced, and therefore generation of defects of blade parts is reduced. Cooling is conducted while pouring is conducted, the grain of the casting is refined, the mechanical performance of the casting is also improved to a certain degree, the quality of the casting is improved, and especially the quality of partition plate blades for an H type compressor is obviously improved; and through the batched trial manufacturing, the partition plate casting produced by adopting the method for blowing the
compressed air in the pouring process is subjected to
nondestructive testing after
grinding, and the quality situation meets the requirement and is greatly improved compared with original partition plate castings.
