Description
Technical Field
The utility model relates to the technical field of hydraulic cylinders, in particular to a hydraulic drive type vacuum valve cylinder.
Background
The oil cylinder is used as a hydraulic actuating element for linear reciprocating motion (or swinging motion), has no transmission clearance and stable motion when in reciprocating motion, and is widely applied to hydraulic systems of various machines.
In die casting equipment, in order to improve the flow of hot metal, the die is usually provided with an exhaust port with a vacuum valve connected to a vacuum tank. If the vacuum valve generates tiny leakage, the pressure of the vacuum tank is increased, and a vacuum tank with larger capacity is needed to be prepared to meet the requirement, so that resource waste is caused and is not a long-term schedule. Therefore, the hydraulic driving type vacuum valve oil cylinder is provided, and the scheme of controlling the vacuum valve to be opened and closed by utilizing the large thrust of the oil cylinder is utilized to prevent the leakage of the vacuum valve.

The utility model aims to solve the technical problems that: in order to overcome the defects in the prior art, the hydraulic drive type vacuum valve oil cylinder is provided.
The technical scheme adopted for solving the technical problems is as follows: a hydraulic drive type vacuum valve cylinder comprises a cylinder body and a valve body which are connected into a whole,
the cylinder body is internally provided with a plunger rod extending into the valve body and a plunger head for limiting the plunger rod, the cylinder body is provided with a first oil port and a second oil port,
a valve core is arranged in the valve body, a vacuum tank connector and a die connector are arranged on the valve body,
the valve core is fixed on the extending end of the plunger rod, and when the plunger rod extends into the valve body, the valve core is inserted into the die connecting port and is matched with the die connecting port.
Furthermore, the die connecting port adopts a cylindrical structure, and one end of the valve core, which is close to the die connecting port, adopts a truncated cone structure and is narrowed towards one end of the die connecting port.
Further, a sealing ring is arranged at the joint of the cylinder body and the valve body.
Further, the first oil port and the second oil port are respectively positioned at two ends of the plunger head.
Furthermore, valves are arranged on the first oil port and the second oil port.
The beneficial effects of the utility model are as follows: the utility model has simple structure, reasonable design and simple and convenient operation, and the plunger rod can drive the valve core to move left and right so as to control the opening or closing of the vacuum valve; the high thrust of the oil cylinder is used for controlling the vacuum valve to be opened and closed so as to ensure the air tightness of the product, and the problem that the pressure of the vacuum tank rises and a vacuum tank with larger capacity is required to be used so as to meet the use requirement is avoided; the mould connector adopts the cylinder structure, and case is close to mould connector one end and adopts round platform structure and narrow to mould connector one end, even if use the case to cause the loss for a long time, the case still can agree with the mould connector to ensure the gas tightness of structure, can not produce and leak.
