Abstract
The utility model provides a two plate type internal recycle direct pressure mould-locking device which consists of a fixed mould, a movable mould, a mould-locking oil cylinder and a mould-moving oil cylinder. The mould-locking oil cylinder is an internal circulating oil cylinder with the outward extended structure of a single piston rod; the outward extended end of the piston rod is connected with the movable mould or the fixed mould; the tail end in the oil cylinder, which is connected with a piston, is provided with a circular shaft body; a shaft sleeve which is arranged at one end of a valve core is sheathed on the circular shaft body and can slide by being matched with the surface of the circular shaft body; the piston rod is connected with the piston with a valve seat to be formed into a logic valve which consists of the circular shaft body, the valve core, the shaft sleeve and the valve seat; and the valve core moves left and right, so that the flow of the oil liquid in an oil cavity with a rod and an oil cavity without the rod which are separated from each other by the piston can be cut off and opened. The device overcomes the defects that the oil liquid largely enters and returns back and the resistance is large when the mould is opened and closed, and prevents the air from being absorbed due to the negative pressure generated by opening the mould since the oil cavity without the rod is internally provided with a segregation board to have hollow cavities which are communicated with the atmosphere. The device is compact in structure, simple and reliable, and low in cost, has large diameter of an oil-passing hole of the logic valve, small resistance and fast speed, and can meet the requirement that a high-precision and high-speed injection molding machine fast locks the mould.
