Abstract: PROBLEM TO BE SOLVED: To provide a lost foam pattern casting method which is excellent in a cleaning effect of decomposed gas of a lost foam pattern and a suppression effect of casting defects.
SOLUTION: When molten metal is poured into a mold which is formed by burying a synthetic resin foam made pattern in molding sand and a product is molded while losing the pattern by the poured molten metal, through holes are formed in the pattern. The casting is conducted while discharging gas generated by losing the pattern outside the mold through a discharge path which is equipped with a discharge gas cleaning means.
