Problems solved by technology
Its main disadvantage is poor controllability of machining accuracy, it is difficult to carry out accurate variable pressure and variable speed pressing work, and it is difficult to be competent for processing with special process requirements
In addition, the system will cause great energy consumption due to unloading or overflow during the process of pressure maintenance and standby, and its low energy efficiency makes its use cost high.

The invention discloses an injection molding machine hydraulic power system. The system comprises a main engine, a controller unit, a motor unit, an auxiliary pump and an electromagnetic reversing valve, the controller unit is used for collecting the pressure, the flow command and the closing command sent by the host wherein the motor unit is internally provided with an encoder, the main pump is driven by the motor unit to work, the rotating speed of the motor unit is fed back to the controller unit in real time through an encoder, a pressure sensor is arranged at the outlet of the main pump,the pressure sensor feeds back collected pressure signals to the controller unit, an auxiliary pump, wherein the auxiliary pump works under the driving of the motor unit, a valve port P of the electromagnetic reversing valve is communicated with the working oil port of the main pump, a valve port A is connected with a control oil passage oil port of the hydraulic control one-way valve, so as to control opening and closing of the hydraulic control one-way valve, in order to meet the requirements of high-pressure and large-flow output. The system adopts a combination mode of a high-pressure mainpump and a low-pressure auxiliary pump, accurate control of the flow can be realized, and various industrial requirements can be met.
Description
technical field [0001] The invention relates to the field of hydraulic power systems of injection molding machines. More specifically, the present invention relates to a high-pressure double-pump hydraulic power system for an injection molding machine. Background technique [0002] The hydraulic power source composed of a motor and a quantitative pump has a good energy-saving effect. Due to the use of a motor, the system has the characteristics of fast response speed and high precision of pressure and flow control. The motor speed changes with the flow demand of the system, without throttling loss. This system has a very significant energy-saving effect when pressing and holding products with a long cooling time. At present, large-scale high-end injection molding machines have higher and higher requirements for energy saving and precision, but the traditional motor pump control system is limited by the motor capacity and pump displacement, and it is difficult to achieve th...
