Abstract
A kind of die cylinder device for recovering hydraulic oil, including die cylinder, oil tank of die-casting machine, recycling oil bottle and nitrogen cylinder, the oil tank of die-casting machine is flexibly connected the top of die cylinder by oil return pipe, the inflation end interface of die cylinder connects nitrogen cylinder by pressure hose, nitrogen table is provided on pressure hose, nitrogen bottle valve is provided on nitrogen cylinder；Pressure hose connects release by pressure hose branch pipe and recycles oil bottle, and pressure hose branch pipe is equipped with oil extraction valve.The utility model solves shortcoming present in traditional technology, can quickly recycle hydraulic oil in oil cylinder and pollute hydraulic oil, for clean manufacturing is promoted to have positive effect by above-mentioned structure design.
Description
Technical field
The utility model is related to Die Casting Industry technical field, specifically, it is a kind of die cylinder hydraulic oil recycling dress
It puts.
Background technology
With the propulsion of clean manufacturing, workshop condition and energy consumption are also included in assessment, and resource consumption is controlled and is required
Higher and higher, the problem of mold hydraulic pressure oil consumption is excessive, highlights.Since the die cylinder that Die Casting Industry uses is heavy load
Oil cylinder when form removal tool or upper and lower mould, the phenomenon that taking away whole cylinder pressure oil there are oil cylinder, in carrying mould or maintenance die, is deposited
Hydraulic oil flows out to ground or waste hydraulic oil problem in hydraulic cylinder.
Therefore, hydraulic oil is taken away to reduce oil cylinder, reduces the consumption of hydraulic oil, it would be highly desirable to need a kind of quick oil recovery of energy
Hydraulic oil in cylinder, and the device of hydraulic oil is not polluted.
Invention content
The purpose of this utility model, which is to provide one kind, can quickly recycle hydraulic oil in oil cylinder and pollute the mould of hydraulic oil
Has oil cylinder hydraulic oil recovery apparatus.
The utility model is to realize above-mentioned purpose by following technological means：
A kind of die cylinder device for recovering hydraulic oil including die cylinder, oil tank of die-casting machine, recycles oil bottle and nitrogen cylinder,
The oil tank of die-casting machine is flexibly connected the top of die cylinder by oil return pipe, and the inflation end interface of die cylinder is soft by pressure resistance
Pipe connects nitrogen cylinder, is provided with nitrogen table on pressure hose, nitrogen bottle valve is provided on nitrogen cylinder；Pressure hose passes through pressure resistance
Hose branch pipe connection release recycling oil bottle, pressure hose branch pipe are equipped with oil extraction valve, when the oil in oil cylinder is discharged by nitrogen
Afterwards, the nitrogen pressure in oil cylinder need to be down to after being balanced with atmospheric pressure, removed and oil by unloading pressure exhaust valve on pressure hose
The pressure hose that cylinder is connected, and oil return pipe is removed, oil cylinder hydraulic oil recycling terminates.
The utility model has the advantages that：
1st, in recyclable oil cylinder more than 80% oil, reduce production cost；
2nd, using simple, easy maintenance；
3rd, hydraulic oil is not polluted；Cost of investment is low.
Description of the drawings
Attached drawing 1 is the structure diagram of the utility model.
Each label is respectively in figure：（1）Die cylinder,（2）Oil tank of die-casting machine,（3）Oil bottle is recycled in release,（4）Nitrogen cylinder,
（5）Oil return pipe,（6）Pressure hose,（7）Nitrogen table,（8）Nitrogen bottle valve,（9）Pressure hose branch pipe,（10）Oil extraction valve,
（11）Mold,（12）Oil cylinder piston.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
Refer to Fig. 1, a kind of die cylinder device for recovering hydraulic oil of the utility model, including die cylinder 1, die casting machine oil
Case 2, release recycling oil bottle 3 and nitrogen cylinder 4, the oil tank of die-casting machine 2 are flexibly connected the top of die cylinder 1 by oil return pipe 5,
The inflation end interface of die cylinder connects nitrogen cylinder 4 by pressure hose 6, and nitrogen table 7, nitrogen cylinder 4 are provided on pressure hose 6
On be provided with nitrogen bottle valve 8；Pressure hose 6 connects release by pressure hose branch pipe 9 and recycles oil bottle 3, pressure hose branch pipe 9
It is equipped with oil extraction valve 10.
During utility model works, mold 11 to be replaced on die casting machine is in die opening state, by the utility model
Pressure hose 6 is inflated end interface with die cylinder 1 and is connect, and confirms that oil extraction valve 10 is closed, slowly opens nitrogen
Bottle valve 8 makes one end of oil cylinder be filled with nitrogen, oil cylinder piston 12 is pushed to move, the hydraulic oil in oil cylinder is promoted to pass through oil return pipe 5
It flows back in oil tank of die-casting machine 2, until oil cylinder piston 12 stops movement in place, shows that oil storage recycling terminates in oil cylinder, closes at this time
Nitrogen bottle valve 8 slowly opens oil extraction valve 10, until the nitrogen pressure being filled in oil cylinder is identical with atmospheric pressure, removes pressure resistance
Hose, and oil return pipe is removed, the hydraulic oil of one oil cylinder of recycling terminates.If there is other oil cylinders on mold, mistake above is repeated
Journey, until the oil of whole oil cylinders all recycles, mold clamping can lower die replacement.
To sum up, the utility model solves shortcoming present in traditional technology by above-mentioned structure design, can be fast
Hydraulic oil in speed recycling oil cylinder, and hydraulic oil is not polluted, for promoting clean manufacturing that there is positive effect.
The advantages of basic principle, main feature and the utility model of the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description
Only illustrate the principle of the utility model, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
Various changes and modifications are had, these various changes and improvements fall within the scope of the claimed invention.The utility model
Claimed range is defined by the appending claims and its equivalent thereof.
