The invention provides a casting production line. The casting production line comprises a modeling line, a casting line, a first engine driven conveying roller line, a second engine driven conveying roller line, a first reversing machine, a first box pushing machine, a second reversing machine, a second box pushing machine, a third reversing machine, a third box pushing machine, a fourth reversing machine and a fourth box pushing machine. The first engine driven conveying roller line is connected between the output end of the modeling line and the input end of the casting line, and accordingly a sand box can be conveyed to the casting line. The second engine driven conveying roller line is connected between the output end of the casting line and the input end of the modeling line, and accordingly the sand box can be conveyed to the modeling line. The casting line, the first engine driven conveying roller line, the casting line and the second engine driven conveying roller line which are sequentially connected end to end are combined to form the casting production line, under the action of the two engine driven conveying roller lines, the production line can still operate normally when the sand box lacks, the modeling line and the casting line can operate in a crossed mode, a complementary function is achieved, and therefore production efficiency is improved.
