A balanced energy saving type injection molding machine, this intelligent energy-saving injection molding machine movement, combining a model using the accumulator reuse of pressure in the hydraulic oil the moving parts of fully automatic driver driving device in, support cylinder movement part weight offset machine, greatly reduces the oil cylinder load combining a model, as a result, quick cylinder bore can be reduced, which can make the cylinder movement speed quickly, At the same time, the load becomes smaller, which can effectively reduce the energy consumption.
