Description
Technical field
The utility model relates to the technical field of hydraulic jack, especially a kind of cylinder water-cooling formula hydraulic jack.
Background technique
Die casting mould is when carrying out die casting operation, and great majority adopt hydraulic jack to promote plug or slide block stretches into the extruding of die casting mould inner chamber, make die casting mould cavity volume relative decrease, and liquid towards metal implements pressurization, improves the tightness of cast structure, reduces casting defect.
But, because liquid metal temperature is very high, when hydraulic cylinder piston rod stretches into die casting mould inner chamber, temperature is delivered to the hydraulic oil of oil cylinder inside by piston rod, after hydraulic oil is heated, the Sealing causing hydraulic jack used is also born temperatures involved, easy generation material ageing and reduce sealing effect, causes hydraulic jack to occur oil leakage phenomenon, thus shortens the working life of hydraulic jack.
Model utility content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provides a kind of cylinder water-cooling formula hydraulic jack that can reduce oil cylinder heating temperature, improve seal durability.
The utility model solves the technological scheme that its technical problem adopts: a kind of cylinder water-cooling formula hydraulic jack, there is cylinder barrel, the rear and front end of described cylinder barrel is respectively equipped with the front cover and rear end cover that match with it, piston rod is provided with in cylinder barrel, piston is provided with between described piston rod and the front end of cylinder barrel, guide sleeve is provided with between piston rod and the rear end of cylinder barrel, the sidewall of described cylinder barrel is provided with two symmetrical horizontal cooling water channels, described front cover is provided with the vertical cooling water channel be connected with two horizontal cooling water channels, described two horizontal cooling water channels part stretched out in outside rear end cover is communicated with respectively and is provided with vertical intake pipe and vertical outlet conduit, jointly mold cooling system is connected with between described vertical intake pipe and vertical outlet conduit.
In order to shorten the whole cylinder water-cooling cycle but, therefore the horizontal cooling water channel of two described in technique scheme, vertically cooling water channel, vertically intake pipe and vertically outlet conduit are around formation rectangle structure.
The beneficial effects of the utility model are: cylinder water-cooling formula hydraulic jack of the present utility model by being provided with the horizontal cooling water channel and vertical cooling water channel that form cooling circuit on cylinder body, and the cooling water utilizing cooling die to use, reach the object preventing cylinder body heat accumulation, the working life of Sealing on cylinder body can be extended like this, avoid oil cylinder to occur the phenomenon of leakage of oil.
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, front cover, 3, rear end cover, 4, piston rod, 5, piston, 6, guide sleeve, 7, horizontal cooling water channel, and 8, vertically cooling water channel, 9, vertically intake pipe, 10, vertically outlet conduit, 11, mold cooling system.
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.
Cylinder water-cooling formula hydraulic jack as shown in Figure 1, there is cylinder barrel 1, the rear and front end of described cylinder barrel 1 is respectively equipped with the front cover 2 and rear end cover 3 that match with it, piston rod 4 is provided with in cylinder barrel 1, piston 5 is provided with between described piston rod 4 and the front end of cylinder barrel 1, guide sleeve 6 is provided with between the rear end of piston rod 4 and cylinder barrel 1, the sidewall of described cylinder barrel 1 is provided with two symmetrical horizontal cooling water channels 7, described front cover 2 is provided with the vertical cooling water channel 8 that cooling water channel 7 horizontal in two is connected, described two horizontal cooling water channel 7 parts stretched out in outside rear end cover 3 are communicated with respectively and are provided with vertical intake pipe 9 and vertical outlet conduit 10, mold cooling system 11 is jointly connected with between described vertical intake pipe 9 and vertical outlet conduit 10.Wherein, described two horizontal cooling water channels 7, vertical cooling water channel 8, vertically intake pipe 9 and vertical outlet conduits 10 are around formation rectangle structure.
But principle is as follows for the cylinder water-cooling of this cylinder water-cooling formula hydraulic jack:
Cooling water in mold cooling system 11 flow in coupled logical horizontal cooling water channel 7 by vertical outlet conduit 10, cooling water in this horizontal cooling water channel 7 flow in vertical cooling water channel 8 again, cooling water in vertical cooling water channel 8 flow in an other horizontal cooling water channel 7 again, cooling water in this horizontal cooling water channel 7 flow in vertical intake pipe 9 again, cooling water in vertical intake pipe 9 is finally eaten again and is flow into mold cooling system 11, the repetition above-mentioned steps that mold cooling system 11 goes round and begins again again, to complete the cylinder water-cooling but process of whole hydraulic jack.
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.
