Description
Technical field
Injector technical field is the utility model is related to, more particularly to a kind of injector moves integrally the control time of part
Road.
Background technology
Injection device in injector is to move integrally part by injection cylinder, charging mechanism, Plasticized component and injection seat
Composition, moving integrally oil cylinder in part can drive injection seat to move back and forth, and make nozzle and contacting dies or separate, injection seat and
The piston rod of oil cylinder is linked into an integrated entity by fixed support, and in injection, pressurize and preformed, caging bolt is ensureing nozzle and mould
In the case of close contact, injection seat is set to be limited to certain position, caging bolt can also bear a part and move integrally oil cylinder
Thrust.But because Hydraulic Elements, pipeline and oil cylinder inevitably have pressure oil leakage, injection seat can be made to bear frequency
Higher bending moment, cause existing injector to move integrally part and fixed support fracture or support bracket fastened limit often occurs
Position bolt all fractures, or because caging bolt loosens, moves down fixed support, cause the piston rod of oil cylinder fracture wait it is former
Barrier.
Utility model content
The problem of for shortcomings and deficiencies in the prior art, the utility model proposes a kind of injector to move integrally part
Control loop, solve due to Hydraulic Elements, pipeline and the leakage of oil cylinder inevitable pressure oil, injection seat is born frequency
Injector caused by higher bending moment moves integrally the failure problems of part.
Technical scheme is used by the utility model solves its technical problem：
A kind of injector moves integrally the control loop of part, including moves integrally part, three position four-way electromagnetic valve, electromagnetism
Iron D1, electromagnet D2, hydraulic control one-way valve, pressure switch and fuel tank, it is described move integrally part by injection seat, caging bolt,
Fixed support and oil cylinder composition, oil cylinder are arranged on fixed support, and fixed support is arranged on injection seat by caging bolt, institute
State oil cylinder and one hydraulic circuit, three position four-way electromagnetic valve are formed by pipeline and hydraulic control one-way valve, three position four-way electromagnetic valve, fuel tank
Electromagnet D1 and electromagnet D2 is connected respectively, close to oil cylinder position connection pressure switch.
Further, the hydraulic control one-way valve uses DFY type hydraulic control one-way valves.
Further, the pressure switch uses PF type pressure switches.
The utility model has the advantages that：The installation site of pressure switch can so be reduced close to oil cylinder
The leakage of oil cylinder hydraulic oil；The utility model is one hydraulic control one-way valve of increase on the basis of the hydraulic circuit of existing injector
With a pressure switch, the loop becomes with the hydraulic control one-way valve locking loop for keeping pressure；So in nozzle of injector
Under conditions of being produced with contacting dies, fixed support is born the thrust of oil cylinder all the time, frequency is born so as to avoid fixed support
The higher bending moment of rate, efficiently solves the failure for moving integrally part.
Brief description of the drawings
Fig. 1 is the utility model overall structure diagram.
Embodiment
With reference to specific embodiment, the utility model is expanded on further.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it is to be understood that reading the content of the utility model instruction
Afterwards, those skilled in the art can make various changes or modifications to the utility model, and these equivalent form of values equally fall within this Shen
Please appended claims limited range.
As illustrated, a kind of injector moves integrally the control loop of part, including move integrally part 1,3-position 4-way
Magnetic valve 2, electromagnet（D1）3rd, electromagnet（D2）4th, hydraulic control one-way valve 5, pressure switch 6 and fuel tank 7, it is described to move integrally portion
Part 1 is made up of injection seat 11, caging bolt 12, fixed support 13 and oil cylinder 14, and oil cylinder 14 is arranged on fixed support 13, fixed
Support 13 is arranged on injection seat 11 by caging bolt 12, and the oil cylinder 14 passes through pipeline and hydraulic control one-way valve 5,3-position 4-way
Magnetic valve 2, fuel tank 7 form a hydraulic circuit, and three position four-way electromagnetic valve 2 connects electromagnet respectively（D1）3 and electromagnet（D2）
4, close to the position of oil cylinder 7 connection pressure switch 6.
The hydraulic control one-way valve 5 uses DFY type hydraulic control one-way valves.
The pressure switch 6 uses PF type pressure switches.
Specifically, when electromagnet D1 is powered, three position four-way electromagnetic valve left UNICOM, pressure oil passes through DFY hydraulic control one-way valves
Into right cavity of cylinder, the fluid of left chamber flows back to fuel tank, and cylinder piston rod, which is moved to the left, drives fixed support and injection seat to left front
Enter, make nozzle of injector and contacting dies.When right cavity of cylinder reaches set pressure, the action of PF pressure switches, make electromagnet
D1 is powered off, and three position four-way electromagnetic valve is in neutral position, and right cavity of cylinder keeps certain pressure by DFY fluid-control one-way valve closures.With
Pressure oil in oil cylinder inevitably to leak, when right cavity of cylinder pressure drops to the following certain limit of setting, PF pressure
The actuating of relay, makes magnetic valve D1 be powered, and pressure oil is again introduced into right cavity of cylinder, reaches set pressure.Thus the control
Loop can reach in nozzle of injector and contacting dies, and fixed support bears the thrust of oil cylinder all the time, avoids fixed support
The higher bending moment of frequency is born, so as to be effectively reduced the failure for moving integrally part.
After the completion of injector injection, magnetic valve D2 is powered, and three position four-way electromagnetic valve right wing UNICOM, pressure oil enters oil cylinder
Left chamber, now DFY hydraulic control one-way valves open, right chamber fluid flows back to fuel tank, and cylinder piston rod moves right, and injection seat is with fixed branch
Frame returns to original position.
