| description | The utility model relates to a servo valve control injection oil path system of a large injection molding machine. According to the technical scheme provided by the utility model, the servo valve control injection oil path system mainly comprises an injection oil cylinder, a pressure sensor, a closed-loop control servo valve, a one-way valve, a high-pressure filter, an inserting valve, a reversing valve, a melting motor and a passing pipeline which are connected. An oil path is compact and simple in structure. Through the injection oil path system, the closed-loop injection control and the closed-loop melting backpressure control can be achieved, the servo valve is quick in response, the repeated position control precision is high and reaches 0.1 mm, the shape and size control precision of products is improved, and the waste of high weight of single product is avoided. |
