The steel formwork for prefabricated concrete blocks proposed by the utility model improves the molding quality of prefabricated concrete blocks by changing the formwork material, is not easy to be damaged, reduces material waste, and increases the turnover times. In the specific pouring process, the above-mentioned combined steel mold is used to enclose a plurality of pouring cavities 13, thereby ensuring that a plurality of prefabricated concrete blocks can be poured at one time.
