Description
Technical field
The utility model relates to the technical field of hydraulic jack, and especially one connects pressurized oil cylinder more.
Background technique
High pressure die casting as a kind of advanced person, high efficiency, high benefit less, without cutting metal heat processing and forming process engineering, be widely used in the production of light metal as the alloy part such as aluminium, magnesium.But lightweight in recent years, high integrated and high performance requirement make the structure of foundry goods, shape more and more complicated, quality is more and more high, occurred that a large amount of wall thickness difference is very large, but adopt the part of casting forming, therefore this type of part brings new challenge to Die Casting.
Extrusion operation many employings oil cylinder pushing plug or slide block stretch in liquid die-casting material, now adopt the words of single only conventional oil cylinder, promote two or more plug, then need to arrange link in addition, plug or slide block are linked to be entirety and synchronously push in dies cavity, oil cylinder certainly will be caused integrally-built complicated.
Model utility content
The technical problems to be solved in the utility model is: for the figuration manufacture of the even die castings of current complex structure, wall unevenness, the utility model provides a kind of designs simplification, can realize multiple plug or slide block simultaneously liquid towards die-casting material carry out squeeze job connect pressurized oil cylinder more.
The utility model solves the technological scheme that its technical problem adopts: a kind ofly connect pressurized oil cylinder more, there is cylinder barrel, be arranged with the piston rod of at least two different sizes in the inner chamber of described cylinder barrel in parallel and be fixed at least two piston rod rear ends and the one piston be slidably matched with inner hole of cylinder wall, the rear end of cylinder barrel is connected with end cap, be provided with one guide sleeve between the front end of cylinder barrel and at least two piston rods, the sidewall of cylinder barrel offer the hydraulic oil inlet be connected with cylinder rod chamber.
In order to reduce the manufacture difficulty of oil cylinder, thus the end cap described in technique scheme and cylinder barrel one-body molded.
In order to make hydraulic oil unnecessary in oil cylinder flow out from hydraulic oil outlet, therefore the sidewall rear end of the cylinder barrel described in technique scheme is also provided with hydraulic oil outlet, described hydraulic oil outlet is located at the gap area place that piston and end cap are collided formed after touch.
The beneficial effects of the utility model are: connect pressurized oil cylinder of the present utility model more, by being arranged with at least two piston rods in parallel in the inner chamber of cylinder barrel, multiple plug or slide block can be connected thus, promotion plug or slide block stretch into transfer mold inner chamber liquid towards die-casting material and carry out squeeze job, thus simplify the overall structure of oil cylinder, improve operating efficiency; Meanwhile, owing to cylinder barrel being only provided with the one piston and one guide sleeve that coordinate with at least two piston rods, also simplify the overall structure of oil cylinder, manufacture cost reduces greatly.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Label in accompanying drawing is: 1, cylinder barrel, 2, piston rod, 3, one piston, 4, end cap, 5, one guide sleeve, 6, hydraulic oil inlet, 7, hydraulic oil outlet, 8, gap area.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1 connect pressurized oil cylinder more, there is cylinder barrel 1, be arranged with the piston rod 2 of at least two different sizes in the inner chamber of described cylinder barrel 1 in parallel and be fixed at least two piston rods 2 rear end and the one piston 3 be slidably matched with cylinder barrel 1 inner hole wall, the rear end of cylinder barrel 1 is connected with end cap 4, be provided with one guide sleeve 5 between the front end of cylinder barrel 1 and at least two piston rods 2, the sidewall of cylinder barrel 1 offer the hydraulic oil inlet 6 be connected with cylinder rod chamber.By being arranged with at least two piston rods 2 in parallel in the inner chamber of cylinder barrel 1, multiple plug or slide block can be connected thus, promotion plug or slide block stretch into transfer mold inner chamber liquid towards die-casting material and carry out squeeze job, thus simplify the overall structure of oil cylinder, improve operating efficiency.
Meanwhile, the every root piston rod 2 had all is equipped with a piston and a guide sleeve in existing most cylinder barrel 1, make the overall dimensions of oil cylinder comparatively large, and manufacture cost is higher.The cylinder barrel 1 of the utility model pressurization oil cylinder is only provided with the one piston 3 coordinated with at least two piston rods 2 and one guide sleeve 5, one piston 3 and one guide sleeve 5 are structure as a whole respectively, such design also simplify the overall structure of oil cylinder, and manufacture cost reduces greatly.
Wherein, described end cap 4 is one-body molded with cylinder barrel 1, greatly reduces the manufacture difficulty of oil cylinder.The sidewall rear end of described cylinder barrel 1 is also provided with hydraulic oil outlet 7, described hydraulic oil outlet 7 is located at gap area 8 place that piston 3 is collided formed after touch with end cap 4, hydraulic oil unnecessary in oil cylinder flows out from hydraulic oil outlet 7, pipeline can be connected with between hydraulic oil outlet 7 and hydraulic oil inlet 6, hydraulic oil is cooled fully in the process through piping, the hydraulic oil of unnecessary spilling can also be made simultaneously to continue to be used.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this model utility technological thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
