Abstract

The utility model discloses a die locking device for an injection molding machine. A rapid oil cylinder rod is arranged in a die locking cylinder in a penetration way, is fixed on a rear cover of the die locking cylinder, and extends into an inner hole of a die locking piston rod. The rapid oil cylinder rod and the inner hole of the die locking piston rod form a closed cavity. The rapid oil cylinder rod is provided with an oil inlet D. An oil port C is formed in the rear cover of the die locking cylinder. Oil inlets A and B are formed in a barrel of the die locking cylinder. Oil entering from the oil inlet D enters the closed cavity of the die locking piston rod through the rapid oil cylinder rod to drive the die locking piston rod to drive a movable die component to rapidly move towards a fixed die component, and oil is replenished through the oil port C. When the movable die component approaches to the fixed die component, the oil port C and the oil inlet D are closed, and high-pressure oil enters the oil inlet B to lock the fixed die component and the movable die component. Oil enters the oil inlet A to drive the die locking piston rod to drive the movable die component to be separated from the fixed die component. The die locking device has the advantages that a rapid die moving action and a high-pressure die locking action are separated, and only a small amount of oil is required by the rapid die moving action.
