The single-cylinder injection molding system mainly consists of a hydraulic cylinder or a pneumatic cylinder. When the injection molding machine receives the injection signal, hydraulic oil or compressed air enters the single cylinder, pushing the piston forward.

Moreover, the injection piston rod will droop due to gravity, thereby reducing the service life of the injection piston rod. Therefore, a linear guide support device for single-cylinder injection molding is proposed. Summary of the Utility Model
