A kind of energy-saving die casting machine hydraulic system; It comprises oil pump 1, pressure flow proportioning valve 2, matched moulds valve 3 and mode transfer valve 4; The output of oil pump 1 links to each other with the input of pressure flow proportioning valve 2; The output of pressure flow proportioning valve 2 is connected with the oil suction chamber of die cylinder 5 and mode transfer motor 6 respectively through matched moulds valve 3 and mode transfer valve 4, and the oil back chamber of die cylinder 5 and mode transfer motor 6 is connected with fuel tank, it is characterized in that the output of said pressure flow proportioning valve 2 is connected with energy accumulating device 8.
Described oil pump 1 is formed in parallel by main oil pump PP1 and auxiliary oil pump PP2, all other unloader A1, the A2 separately that be connected to of the output of main oil pump PP1 and auxiliary oil pump PP2.
Described energy accumulating device 8 is made up of magnetic valve A3, magnetic valve A4 and accumulator 9, and magnetic valve A3 is connected between the oil outlet end and pressure flow proportioning valve 2 of accumulator 9, and magnetic valve A4 is connected between the oil inlet end and pressure flow proportioning valve 2 of accumulator 9.
The beneficial effect of the utility model:
The utility model passes through energy accumulating device of parallel connection in the proportioning valve exit; Thereby the power and the pump delivery of motor have been reduced; Gap in the die casting machine action is oil-filled toward energy accumulating device; Drain the oil at the time standby energy accumulating device of mould assembling action and to replenish the pressure of action, fully used energy.Thereby save the energy up to 40%, reach the purpose of economize on electricity and protection fluid pressure line, and improve pressure and flow accuracy, raising speed increases efficient, reduces noise.
The power and the pump delivery of the utility model motor reduce 50%, can energy-conservation about 50%-60%.
Release energy during the utility model matched moulds, reach than higher closure pressing speed.
The utility model stable action is quick on the draw etc.
