A kind of hydraulic system of Clamping Device of Injection Moulding Machine, comprise flow check piston, solenoid valve A, oil cylinder, solenoid valve B and oil pump, the T1 interface of described solenoid valve A connects fuel tank by flow check piston, the P1 interface of solenoid valve A connects oil pump by pipeline, the A1 interface of solenoid valve A connects the rodless cavity of oil cylinder by pipeline, the B1 interface of described solenoid valve A connects the rod chamber of oil cylinder; The rodless cavity of described oil cylinder is also by the A2 interface of pipeline connected electromagnetic valve B, and the B2 interface of solenoid valve B and T2 interface are all connected to the output port of flow check piston, and the P2 interface of solenoid valve B connects the input port of flow check piston.
As further program of the utility model: solenoid valve A is provided with electromagnet D2 and electromagnet D3.
As the utility model further scheme: solenoid valve B is provided with electromagnet D1.
Compared with prior art, the beneficial effects of the utility model are: this practicality adopts flow check piston, not only make the response time of hydraulic system more rapid, and energy-conserving and environment-protective, greatly reduce electric fittings cost simultaneously.During use, as long as find the flow check piston of suitable bore in debug process, the match is successful, and throttle response will be very fast, thus the working efficiency of machine is improved greatly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, in the utility model embodiment, a kind of hydraulic system of Clamping Device of Injection Moulding Machine, comprise fuel tank 1, flow check piston 2, solenoid valve A3, oil cylinder 4, solenoid valve B5 and oil pump 6, the T1 interface of described solenoid valve A3 connects fuel tank 1 by flow check piston 2, so that oil return, the P1 interface of solenoid valve A3 connects oil pump 6 by pipeline, when oil pump 6 works, fuel feeding is carried out to system, fuel feeding conducting is controlled by solenoid valve A3, the A1 interface of solenoid valve A3 connects the rodless cavity of oil cylinder 4 by pipeline, after the conducting of solenoid valve A3, hydraulic oil enters into the rodless cavity interior promotion piston movement of oil cylinder 4, thus oil cylinder is moved right, realize normal matched moulds, the B1 interface of described solenoid valve A3 connects the rod chamber of oil cylinder 4, to realize Collaborative Control, solenoid valve A3 is provided with electromagnet D2 and electromagnet D3, by electromagnet D2 and electromagnet D3 Controlling solenoid valve A3, to realize two kinds of on states.
The rodless cavity of described oil cylinder 4 is also by the A2 interface of pipeline connected electromagnetic valve B5, the B2 interface of solenoid valve B5 and T2 interface are all connected to the output port of flow check piston 2, and the P2 interface of solenoid valve B5 connects the input port of flow check piston 2, control to realize oil return, solenoid valve B5 is provided with electromagnet D1.
Working principle of the present utility model is:
Realize matched moulds: the D3 action of solenoid valve A3, hydraulic oil by oil pump 6 to P1 interface, arrive A1 interface, finally flow into the rodless cavity of oil cylinder 4, oil cylinder moves right, and realizes normal matched moulds, the hydraulic oil now in cylinder rod chamber through B1 interface to T1 interface, to P2 interface, finally from B2 interface backflow fuel tank 1.In matched moulds process, the electromagnet D1 action of solenoid valve B5, the hydraulic oil of oil cylinder 4 rod chamber flows to T1 interface from B1 interface, arrive P2 interface, finally flow into the rodless cavity of oil cylinder 4 from A2 interface, realize differential matched moulds, by the flow check piston 2 matched, enough pressure reduction can be set up, meet the needs driving cylinder movement.
Realize die sinking: the electromagnet D2 action of solenoid valve A3, hydraulic oil flows in the rod chamber of oil cylinder 4 from P1 interface, B1 interface successively, oil cylinder is to left movement, realize die sinking, hydraulic oil now in oil cylinder rodless cavity through A1 interface to T1 interface, from P2 interface to B2 interface, be finally back in fuel tank 1.In die sinking process, electromagnet D1 action, the hydraulic oil in oil cylinder 4 rodless cavity to T1 interface, simultaneously flows into flow check piston 2, then oil sump tank from A2 interface to P2 interface through A1 interface, realizes the function that die sinking or end slow down
Injection machine closing liquid pressing system in the market, the electromagnetic relief valve that adopts carries out pressure flow adjustment more.This practicality is improved by oil circuit, utilize flow check piston 2 to replace electromagnetic relief valve, not only the response time is more rapid, energy-conserving and environment-protective, greatly reduce electric fittings cost: general about 500 yuan of the electromagnetic relief valve of a middle-size and small-size machine, and a flow check piston price is also with regard to a few yuan simultaneously.As long as find the flow check piston of suitable bore in debug process, the match is successful, and throttle response can be very fast, and the efficiency of machine can improve greatly.
