Description
Technical field
The utility model relates to the technical field of hydraulic jack, especially a kind of die casting mould high efficiency cooling 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: in order to solve the problem proposed in above-mentioned background technology, and the utility model provides a kind of die casting mould high efficiency cooling hydraulic jack that can reduce oil cylinder heating temperature fast, greatly improve seal durability.
The utility model solves the technological scheme that its technical problem adopts: a kind of die casting mould high efficiency cooling hydraulic jack, there is cylinder barrel, piston rod and be fixed on piston rod rear end and the piston be slidably matched with inner hole of cylinder wall, described cylinder barrel rear end is connected with end cap, guide sleeve is provided with between cylinder barrel front end and piston rod, cylinder barrel sidewall is provided with the hydraulic oil inlet be connected with cylinder rod chamber, rear end is also provided with hydraulic oil outlet to cylinder barrel sidewall, described piston rod is provided with the cooling channel of some U-shaped structures along its length direction, cooling water passes into from the cooling water intake of cooling channel and discharges from the coolant outlet of cooling channel.
Further specifically, described hydraulic oil outlet is located at the gap area place that described piston and end cap are collided formed after touch.
In order to reduce the heating temperature of piston rod further, therefore in the cooling channel of described some U-shaped structures, several cooling water intakes and several coolant outlets are cellular formal distribution.
Further specifically, described cylinder barrel and end cap are structure as a whole.
The beneficial effects of the utility model are: die casting mould high efficiency cooling hydraulic jack of the present utility model, by being provided with the cooling channel of some U-shaped structures on the length direction of piston rod, cooling water passes into from the cooling water intake of cooling channel and discharges from the coolant outlet of cooling channel, and the heat produced in the course of the work by piston rod is run out by cooling water drainage; Simultaneously, by several cooling water intakes in the cooling channel of some U-shaped structures and several coolant outlets are designed to cellular formal distribution, piston rod is not only made to lower the temperature fast, can also ensure that the cooling efficiency at each position of piston rod is consistent, and then oil cylinder heating temperature can be reduced fast, and greatly improve seal durability.
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, piston, 4, end cap, 5, guide sleeve, 6, hydraulic oil inlet, 7, hydraulic oil outlet, 8, cooling channel, 81, cooling water intake, 82, coolant outlet, 9, 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, die casting mould high efficiency cooling hydraulic jack, have cylinder barrel 1, piston rod 2 and be fixed on piston rod 2 rear end and the piston 3 be slidably matched with cylinder barrel 1 inner hole wall, cylinder barrel 1 rear end is connected with end cap 4, and cylinder barrel 1 and end cap 4 are structure as a whole.
Wherein, guide sleeve 5 is provided with between cylinder barrel 1 front end and piston rod 2, cylinder barrel 1 sidewall is provided with the hydraulic oil inlet 6 be connected with cylinder rod chamber, and rear end is also provided with hydraulic oil outlet 7 to cylinder barrel 1 sidewall, and hydraulic oil outlet 7 is located at gap area 9 place that piston 3 is collided formed after touch with end cap 4.
Piston rod 2 is provided with the cooling channel 8 of some U-shaped structures along its length direction, and cooling water passes into from the cooling water intake 81 of cooling channel 8 and discharges from the coolant outlet 82 of cooling channel 8.In the cooling channel 8 of some U-shaped structures, several cooling water intakes 81 and several coolant outlets 82 are in cellular formal distribution.
This die casting mould high efficiency cooling hydraulic jack, by being provided with the cooling channel 8 of some U-shaped structures on the length direction of piston rod 2, cooling water passes into from the cooling water intake 81 of cooling channel 8 and discharges from the coolant outlet 82 of cooling channel 8, is run out by the heat that piston rod 2 produces in the course of the work by cooling water drainage; Simultaneously, by several cooling water intakes 81 and several coolant outlets 82 in the cooling channel 8 of some U-shaped structures are designed to cellular formal distribution, piston rod 2 is not only made to lower the temperature fast, can also ensure that the cooling efficiency at each position of piston rod 2 is consistent, and then oil cylinder heating temperature can be reduced fast, and greatly improve seal durability.
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.
