Abstract
The utility model relates to a power saving system structure, in particular to a power saving system structure of an injection molding machine. The power saving system structure comprises a switching circuit, the injection molding machine, an intelligent control unit and a speed regulating controller, and is characterized in that the intelligent control unit is connected with the speed regulating controller through the switching circuit; and the speed regulating controller is connected with the injection molding machine through the switching circuit. In a cycle operation process of the injection molding machine, a working state signal from the injection molding machine is automatically detected by the intelligent control unit, the information is analyzed and calculated, and data information required by working pressure and working flow of a current working state of the injection molding machine are transferred to the speed regulating controller; and thus, the rotation speed of an oil pump of the injection molding machine is regulated by the speed regulating controller, and the actual oil supply capacity of the oil pump is consistent with the flow demand of the injection molding machine, thereby fulfilling the aim of saving electric energy consumption.
Description
Technical field
The utility model relates to a kind of energy conserving system structure, particularly a kind of injection machine power saving apparatus structure.
Background technology
The power consumption of hydraulic oil pump motor accounts for more than 80% of whole injection machine power consumption, and therefore, reducing hydraulic oil pump motor power consumption is the key of injection machine energy-saving.The fuel delivery of oil pump is invariable.When the oil mass demand of injection machine changes, come regulating load pressure and load flow by the overflow valve or the pressure proportioning valve that are installed in the oil pump outlet, satisfy the needs of injection machine working conditions change.
In fact, the hydraulic injection molding machine system is pressure and all bigger load of flowed fluctuation, and in matched moulds, locked mode, injection, pressurize, cooling, die sinking, the different operating stage such as eject, its pressure and flow all will take place clocklike to change.In a dust cycle, the actual pressure and the actual flow of injection machine change, the time little, almost nil sometimes when big.At actual flow hour, the fuel delivery of oil pump is far longer than load actual consumption amount, and supply exceed demand, more than needed is in hydraulic oil under the high pressure conditions all through the overflow valve overflow.Hydraulic oil under the high pressure conditions is emitted great amount of heat energy behind overflow valve, the energy of this part dissipation is actually Oil pump electrical machinery and absorbs the part the electric energy from electrical network.The time that the low discharge state is kept is long more, and the electric energy that is dissipated is also just big more.Therefore, there is the severe energy waste problem in the hydraulic injection molding machine system.
The utility model content
The utility model provides a kind of injection machine power saving apparatus structure to the deficiency of prior art.
The utility model is realized through following technical scheme:
A kind of injection machine power saving apparatus structure comprises change-over circuit, injection machine, intelligent control unit and speed setting controller, and said intelligent control unit connects speed setting controller through change-over circuit, and speed setting controller connects injection machine through change-over circuit.
Further, said change-over circuit is provided with a switching assembly.
Further, said changeover module is a kind of device that is provided with the structure of switching controls injection machine power-saving running and these two kinds of working methods of civil power operation.
Further, be provided with oil pump, motor, overflow valve and pressure proportioning valve in the said injection machine.
Further; Said intelligent control unit is that a kind of operation information of collecting from injection machine that is provided with carries out comprehensive analysis processing; Go out the economize on electricity running speed curve of injection machine oil pump then according to the economize on electricity calculated with mathematical model of optimizing, give the device of speed setting controller structure the data information transfer of economize on electricity running speed curve again.
Further, said speed setting controller is a kind of device of regulating the processor of injection machine oil pump running behind the data message that receives intelligent control unit that is provided with.
The beneficial effect of the utility model is: in injection machine periodic duty process; Intelligent control unit detects the working state signal that comes from injection machine automatically; And these information are analyzed and calculate; Give speed setting controller the data information transfer of the operating pressure of injection machine current working state and working flow requirement; Thereby speed setting controller is regulated the rotating speed of injection machine oil pump, makes the actual fuel delivery of oil pump consistent with the traffic demand of injection machine to eliminate overflow phenomena, reaches the purpose of saving power consumption.
