Abstract
The utility model discloses one kind to lift cylinder structure, including cylinder barrel, the internal slide of the cylinder barrel is connected with piston, piston rod is fixedly connected with the top of the piston, upper cylinder cover is welded with the top of the cylinder barrel, and upper cylinder cover is run through on the top of piston rod, the top of the cylinder barrel is threaded with flange.The apparatus structure designs advantages of simple, easy to operate, is ined succession injection mechanism by hoist cylinder piston rod, cylinder piston rod moves up and down, injection mechanism is moved to required position, is connected between cylinder barrel and flange with fine thread, and so installation is less likely to be damaged the O-ring seals on cylinder barrel, lower cylinder cap is directly welded on cylinder barrel, piston packing avoids welding deformation position, and postwelding does not need secondary operation, safety and stability, it is applied widely, be advantageous to popularize.
Description
Technical field
The utility model belongs to lift cylinders technical field, and in particular to one kind lifting cylinder structure.
Background technology
Common horizontal cold-chamber die casting machine will have several injection gears to adapt to the needs of different moulds.Common rod-pulling type
Oil cylinder volume is big, and part is more, and cost is high.If directly processing screw thread on upper cylinder cover, to increase the length of cylinder cap, also to add
Work goes out internal thread, and cylinder barrel is screwed into upper cylinder cover during assembling, is easily damaged O-ring.It is unfavorable for widely popularizing.
Utility model content
The purpose of this utility model is to provide a kind of lifting cylinder structure, asked with solve to propose in above-mentioned background technology
Topic.
To achieve the above object, the utility model provides following technical scheme：One kind lifting cylinder structure, including cylinder barrel, institute
The internal slide for stating cylinder barrel is connected with piston, and piston rod, the top welding of the cylinder barrel are fixedly connected with the top of the piston
There is upper cylinder cover, and upper cylinder cover is run through on the top of piston rod, the top of the cylinder barrel is threaded with flange.
Preferably, connected between the cylinder barrel and flange by fine thread.
Preferably, the bottom of the piston is fixedly connected with injection mechanism.
Preferably, the surface of the cylinder barrel has sprayed epoxy resin etch resistant layer.
Technique effect of the present utility model and advantage：The lifting cylinder structure, structure design advantages of simple is easy to operate, leads to
Hoist cylinder piston rod is crossed in succession injection mechanism, cylinder piston rod moves up and down, and injection mechanism is moved to required position, cylinder barrel with
Connected between flange with fine thread, so installation is less likely to be damaged the O-ring seals on cylinder barrel, and lower cylinder cap is directly welded in cylinder barrel
On, piston packing avoids welding deformation position, and postwelding does not need secondary operation, and safety and stability is applied widely, is advantageous to push away
Wide and popularization.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is sectional view of the present utility model；
Fig. 3 is top view of the present utility model.
In figure：1 piston rod, 2 upper cylinder covers, 3 flanges, 4 cylinder barrels, 5 pistons.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
The utility model provides a kind of lifting cylinder structure as Figure 1-3, including cylinder barrel 4, the inside of the cylinder barrel 4
Piston 5 is slidably connected, the top of the piston 5 is fixedly connected with piston rod 1, and the top of the cylinder barrel 4 is welded with upper cylinder cover
2, and upper cylinder cover 2 is run through on the top of piston rod 1, the top of the cylinder barrel 4 is threaded with flange 3.
Further, connected between the cylinder barrel 4 and flange 3 by fine thread.
Further, the bottom of the piston 5 is fixedly connected with injection mechanism.
Further, the surface of the cylinder barrel 4 has sprayed epoxy resin etch resistant layer.
The lifting cylinder structure, structure design advantages of simple is easy to operate, is ined succession injection mechanism by hoist cylinder piston 5,
Cylinder piston rod 1 moves up and down, and injection mechanism is moved to required position, is connected between cylinder barrel 4 and flange 3 with fine thread, this
Sample installation is less likely to be damaged the O-ring seals on cylinder barrel 4, and upper cylinder cover 2 is directly welded on cylinder barrel 4, and piston packing is avoided welding
Deformation position, postwelding do not need secondary operation, and safety and stability is applied widely, is advantageous to popularize.
Finally it should be noted that：Preferred embodiment of the present utility model is the foregoing is only, is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it can still modify to the technical scheme described in foregoing embodiments, or to which part technical characteristic
Progress equivalent substitution, all within the spirit and principles of the utility model, any modification, equivalent substitution and improvements made etc.,
It should be included within the scope of protection of the utility model.
