The invention discloses a control system and method capable of being used for servo mold closing of an injection molding machine, and belongs to an injection molding machine servo control method. The system comprises a parameter setting module and a judgment module. The parameter setting module is connected with the judgment module and used for setting and transmitting the mold closing rapidness position and speed, mold closing low-pressure pressure and position and mold closing high-pressure pressure and time to a parameter calculation and conversion module. The judgment module is connected with the parameter calculation and conversion module and a servo driver and used for judging whether an instruction of starting of mold closing is received or not. The mold closing action of the injection molding machine or similar equipment is controlled in a servo control manner, and the mold closing action can be rapidly, accurately and stably conducted; the control precision can be greatly improved, and due to servo control, hydraulic oil does not need to be adopted, and the control system and method are particularly suitable for being used under the severe environment conditions; and meanwhile, acceleration speed, deceleration speed and other parameters in the control system can be adjusted, the mold closing action is more stable, and the using cost of the equipment is effectively saved.
