Technical Field
The utility model relates to a metal forming field, specificly is a high-speed oil return buffering oil tank structure.
Background
In the die-casting industry, when a cold chamber die-casting machine carries out rapid injection action, because the motion speed of an injection piston is high, the instantaneous flow rate of an oil return pipe of a front cavity of an injection oil cylinder is overlarge and exceeds the flow rate requirement of a hose pipeline, and the conventional common hose cannot meet the working condition. At present, the common treatment mode is to change an oil return pipe of a front cavity of the injection oil cylinder into a large-diameter steel pipe and directly connect the oil return pipe back to a main oil tank. The mode has high requirements on processing precision and installation; meanwhile, a hydraulic valve is required to be additionally arranged on the front cylinder cover of the injection cylinder, and the injection valve plate is required to be connected with a control oil pipe to control the injection cylinder, so that the trend of a pipeline is more complicated, and the safety protection of the hydraulic valve is required to be realized because the front cylinder cover of the injection cylinder is closer to the knockout device.
Therefore, it is necessary to design a device which has simple structure, is convenient to install and can ensure good oil return effect.
SUMMERY OF THE UTILITY MODEL
To the above-mentioned condition, for overcoming prior art's defect, the utility model provides a high-speed oil return buffering oil tank structure, fine solution press the quick injection oil return velocity of flow high, the problem that hose life is low, simple to operate simultaneously.
The utility model provides a high-speed oil return buffering oil tank structure, its technical scheme who solves includes oil tank flange, oil tank inner bag, oil tank casing, oil tank flange and oil tank inner bag sealing connection, and oil tank casing cover forms the cavity between oil tank casing and the oil tank inner bag in the outside of oil tank inner bag, has seted up the aperture on the lateral wall of oil tank inner bag, aperture and cavity intercommunication, has seted up the oil-out on the lateral wall of oil tank casing.
Preferably, the top of oil tank casing be equipped with air cleaner, the cavity passes through air cleaner and outside air intercommunication, can effectively avoid because the untimely produced backpressure of oil return.
Preferably, the top of the inner container of the oil tank is of a sealing structure.
Preferably, the inner diameter of the oil tank flange is larger than the diameter of the small holes, and the small holes are uniformly distributed on the side wall of the oil tank liner in the circumferential direction.
The utility model discloses the structure is ingenious, simple to operate, fine realization to pressing the buffering of penetrating high-speed oil return, simple to operate simultaneously, oil return structure's oil return connecting pipe can use less size, makes whole pipe connection more simple and convenient, and the overall arrangement is more pleasing to the eye.

Detailed Description
The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.
According to the drawings 1 to 2, the utility model discloses an oil tank flange 1, oil tank inner bag 2, oil tank casing 3, oil tank flange 1 and oil tank inner bag 2 sealing connection, oil tank casing 3 cover in oil tank inner bag 2's outside, vacuole formation 6 between oil tank casing 3 and the oil tank inner bag 2 has seted up aperture 4 on the lateral wall of oil tank inner bag 2, aperture 4 and cavity 6 intercommunication have seted up oil-out 5 on the lateral wall of oil tank casing 3.
In order to prevent the blockage when fluid flows into the oil tank inner container 2, the top of the oil tank shell 3 is provided with an air filter 7, and the cavity 6 is communicated with the outside air through the air filter 7, so that the back pressure generated due to untimely oil return can be effectively avoided.
In order to prevent the oil from being flushed out from the air filter 7, the top of the oil tank inner container 2 is of a sealing structure.
In order to ensure better buffering effect, the inner diameter of the oil tank flange 1 is larger than the diameter of the small holes 4, and a plurality of small holes 4 are uniformly distributed on the side wall of the oil tank liner 2 along the circumference; the oil tank flange 1's of here internal diameter is greater than the diameter of every aperture 4 far away, when pressing the oil return fast and getting into oil tank inner bag 2 through oil tank flange 1, fluid can at first be stored in oil tank inner bag 2 this moment, along with the entering of quick fluid, when the liquid level surpassed aperture 4 on the oil tank inner bag 2, during fluid passes through aperture 4 entering cavity 6, can effectually slow down the velocity of flow of fluid.
In order to realize the connection of the oil tank flange 1 and the oil tank inner container 2, the oil tank flange 1 and the oil tank inner container 2 are connected through a conical cylinder, and the inner diameter of one end, close to the oil tank inner container 2, of the conical cylinder is larger than the inner diameter of one end, close to the oil tank flange 1, of the conical cylinder, so that the buffering effect is further improved.
The oil tank flange 1 is connected with an oil return opening of the injection oil cylinder, and the oil outlet 5 is connected with the main oil tank.
In order to ensure better using effect, the connecting parts between the oil tank flange 1 and the oil tank inner container 2 and between the oil tank inner container 2 and the oil tank shell 3 are welded to ensure sealing.
When the utility model is used, firstly the oil tank flange 1 is connected with the oil return port of the injection oil cylinder, the oil outlet 5 on the oil tank shell 3 is connected with the main oil tank, when the rapid injection action is carried out, because the injection piston has rapid movement speed, the instantaneous flow rate of the oil return pipe of the front cavity of the injection oil cylinder is large, the rapid oil return through the device can enter the oil tank inner container 2 through the oil tank flange 1, because the inner diameters of the oil tank flange 1 and the oil tank inner container 2 are large, the rapid oil can be firstly stored in the oil tank inner container 2 at the moment, along with the increase of the oil, the liquid level in the oil tank inner container 2 rises, when the liquid level in the oil tank inner container 2 exceeds the small hole 4 on the side wall of the oil tank inner container 2, the oil in the oil tank inner container 2 can flow into the cavity 6 between the oil tank shell 3 and the oil tank inner container 2 through the small hole 4, quick fluid is because the internal diameter of oil tank flange 1 is far greater than the diameter of aperture 4 when passing through oil tank flange 1, can effectual reduction fluid velocity of flow this moment, reaches the effect of buffering.
Furthermore the utility model discloses still through having designed the air cleaner 7 of arranging 3 tops in the oil tank casing in, guarantee cavity 6 and outside air's that can be fine intercommunication, the air in cavity 6 can be discharged through air cleaner 7, can effectively avoid because untimely produced backpressure of oil return, in addition through the upper end design seal structure at oil tank inner bag 2, make fluid can only flow into cavity 6 through aperture 4 in, can effectually prevent that fluid from flowing into the too fast time fluid from air cleaner 7 outflow.
The utility model discloses the structure is ingenious, simple to operate, fine realization to pressing the buffering of penetrating high-speed oil return, simple to operate simultaneously, oil return structure's oil return connecting pipe can use less size, makes whole pipe connection more simple and convenient, and the overall arrangement is more pleasing to the eye.
