A lubricating system is installed in a common injection molding machine which includes a stationary mold half unit, a movable mold half unit which can be moved towards and away from the stationary mold half unit, a toggle mechanism coupled with the movable mold half unit so as to be driven to move the movable mold half unit, a mold pressing hydraulic cylinder having a piston rod coupled with the toggle mechanism so as to drive the toggle mechanism, and an oil feed system coupled with the mold pressing hydraulic cylinder so as to provide hydraulic pressure for the mold pressing hydraulic cylinder to drive the toggle mechanism. The lubricating system includes a pump driving hydraulic cylinder coupled with the oil feed system so that the pump driving hydraulic cylinder can be operated synchronously with the mold pressing hydraulic cylinder, an oil tank for storing lubricating oil, and a lubricating oil pump coupled with the oil tank, the toggle mechanism and the piston rod of the pump driving hydraulic cylinder so that the oil pump is activated by the piston rod of the pump driving hydraulic cylinder so as to receive lubricating oil from the oil tank and then force the lubricating oil from the oil pump to the toggle mechanism in order to lubricate the latter.
