The invention relates to a synchronous press forming method of electric power fittings, comprising the following steps: placing workpieces to be pressed among multiple pressing molds, wherein all pressing molds can approach to or depart from the workpieces to be pressed at the same time; causing all pressing molds to approach to the workpieces to be pressed together to complete the pressing; and causing the pressing molds to return to positions prior to the pressing, and taking off the pressed workpieces. The pressing is completed by causing the multiple pressing molds to approach to or departfrom the workpieces to be pressed at the same time, the uniformity of the pressing force can be ensured by the simultaneous pressing of the surfaces of the multiple workpieces to be pressed, and meanwhile, simultaneous press forming of multiple surfaces of the multiple workpieces to be pressed can realized by the multiple pressing molds, so that the pressing efficiency is high.
