The present invention discloses a control method and system for a material taking device of an injection blow molding machine, relating to the technical field of injection blow molding. A material taking mechanism is controlled to move up and down so that suction cups of the material taking mechanism suck workpieces processed by the injection blow molding machine and drive the workpieces to a preset position. A material clamping hand of a receiving mechanism is controlled to clamp the workpieces. When the material clamping hand clamps the workpieces, the suction cups of the material taking mechanism are controlled to release the adsorption force on the workpieces. The material clamping hand of the receiving mechanism is controlled to place the workpieces on a workpiece conveyor belt, and an oil cylinder or air cylinder of the receiving mechanism is controlled to fine-tune the positions of the workpieces during movement. Compared with the prior art, the material taking device for an injection blow molding machine can place workpieces stably on the workpiece conveyor belt to avoid damage when falling, and can take out multiple workpieces simultaneously.
