Put, described slop control device makes described injection machine consistent with the action slope of described converter, described slop control device is even
It is connected to motor speed control device, described motor speed control device is together with described pressure proportional controller, ratio flow control
Device together connects converter.
Wherein, described motor speed control device includes speed selection control, pressure anaiog signal controller, pressure current
Amount anaiog signal controller, described speed selection control provides the parameter request selecting to reach injection mo(u)lding, described pressure class
Receive the pressure anaiog signal of selection than signal controller, to export stable optimal rotating speed, and set up stable system pressure
Force value, described pressure flow anaiog signal controller receives pressure anaiog signal and flow anaiog signal, through computing, compares and puts
Greatly, reduce rear output valve, be supplied to frequency converter controller, make motor and hydraulic pump reach optimum state.
Implement this utility model embodiment, have the advantages that and injection machine and frequency conversion can be made by slope controller
The drive actions slope compliance of device, and the rotating speed of motor can be reached optimum via motor speed controller,
Multiple difference progresses are selected to high pressure low speed or low pressure low speed condition of molding automatization, is not required to worry because of operator's misspecification
Problem, make the too low build-up of pressure of output frequency unstable and the situation of product quality and efficiency of affecting occur.
