The invention discloses a sand casting production technology. The sand casting production technology comprises the following specific steps: raw material inspection, core making, shaping, mold matching, melting and pouring, in-mold cooling, shake-out, heat treatment, cleaning and polishing, casting examination, machining, deburring, rough cleaning, pressure testing, final inspection, final cleaning and putting in storage. With adoption of the technology, multiple inspection procedures such as raw material inspection, mold matching, casting examination, pressure testing and final inspection areperformed respectively, so that manufacturing precision and quality can be monitored in the whole production process of castings, and production of defective products is prevented; meanwhile, the mold is manufactured through front procedures of core making and shaping, so that the mold is produced specially for batch products, and production efficiency of a production line is increased greatly.
