PURPOSE:To advantageously realize automation of packing operation of self- curing molding sand into a flask with simple structure without lowering mold quality by working a swing arm having conveying passage based on data for model operation beforehand stored. CONSTITUTION:The second step swing arm 50 is fitted to tip part of the first step swing arm 10, and the self-curing molding sand is discharged into the flask 82 at lower part from a discharging hole 60 arranged at tip part of the second step swing arm 50 through the conveying passage arranged these arms, and also the discharge hole 60 is shifted on the flask 82 based on swing operation of the swing arms 10, 50 to pack the self-curing molding sand into the flask 82. In this molding machine for self-curing mold, at the time of discharging the above self-curing molding sand into the flask 82, operations of swing driving means of the swing arms 10, 50 are controlled so as to realize again the packing of self-curing molding sand into the above flask 82 at the time of model- operating based on the data for model operation beforehand stored in the storage device for storing the swing formation of the swing arms 10, 50.
