Abstract

The utility model relates to a hydraulic cylinder, particularly a leak-less compound oil cylinder, which comprises a pressurizing outer oil cylinder and an inner oil cylinder, wherein the inner oil cylinder is arranged in a piston rod of the pressurizing outer oil cylinder; the pressurizing outer oil cylinder is a single-cylinder type hydraulic cylinder, and the inner oil cylinder is a double-cylinder type hydraulic cylinder. The purpose is to design a leak-less compound oil cylinder that hydraulic oil can not leak outside. The utility model has the advantages of little energy consumption, high efficiency, safe production, etc.

Description

Leakless combined oil cylinder
Technical field
The utility model relates to oil hydraulic cylinder, particularly a kind of Leakless combined oil cylinder.
Background technique
On the injection moulding shoe machine,, need to produce the oil cylinder of big pressure because of the big reason of injection moulding mold clamping pressure.The composite oil cylinder that adopts in the present technology, it comprises the outer oil cylinder of supercharging and closes inner cylinder soon, fast and inner cylinder is located in the piston thick stick of the outer oil cylinder of supercharging, and closing soon of footwear mould relies on quick inner cylinder to finish, and the supercharging of matched moulds relies on upper and lower two oil pocket superchargings of the outer oil cylinder of supercharging to realize with separating.Its deficiency: because outer upper and lower two oil pockets of oil cylinder of supercharging all are full of hydraulic oil because of need of work, and the oil cylinder of a kind of vat of common employing, big piston in the outer oil cylinder of supercharging, this oil cylinder is big because of oil pressure, in the working procedure, be easy to generate and leak, the hydraulic oil that leaks had both produced unnecessary waste, had polluted the operational site again, and was bigger to the production negative effect.
Summary of the invention
The purpose of this utility model is the Leakless combined oil cylinder that a kind of hydraulic oil of design can not leak.
In order to achieve the above object, the utility model adopts following technical solution: a kind of Leakless combined oil cylinder, comprise outer oil cylinder of supercharging and inner cylinder, inner cylinder is located in the piston rod of the outer oil cylinder of supercharging, the outer cylinder cover of piston rod outer end and pressurization hydraulic that closes soon in the inner cylinder is fixedlyed connected, and it is characterized in that being provided with in inner cylinder two working hydraulic pressure chambeies, establishes an oil circuit again closing piston rod soon, this oil circuit is connected with last hydraulic pressure cavity in the inner cylinder, and the outer oil cylinder of supercharging is the single casing oil hydraulic cylinder.
Because the separation of footwear mould and close soon all and finish by upper and lower two the working hydraulic pressure chambeies of inner cylinder, the supercharging of matched moulds is realized by the upper oil cavitie supercharging of the outer oil cylinder of supercharging, outer oil cylinder is the single casing oil hydraulic cylinder, even the unique last hydraulic pressure cavity of outer oil cylinder has small leakage, also can leak into fuel tank, therefore hydraulic oil can not take place in the course of the work and leak by drain tap.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the structural drawing of present embodiment.
Embodiment
As shown in Figure 1 and Figure 2, present embodiment comprises outer oil cylinder (1) of supercharging and inner cylinder (6), and inner cylinder (6) is located in the piston rod (7) of the outer oil cylinder of supercharging, fixedlys connected with the outer cylinder cover (17) of pressurization hydraulic in piston rod (11) outer end of closing soon in the inner cylinder.Be provided with two working hydraulic pressure chambeies (3), (5) in the inner cylinder (6), in closing piston rod (11) 7 soon, be provided with two oil circuits (18), (19), be connected with two working hydraulic pressure chambeies (5), (3) respectively, constitute the two-cylinder type oil hydraulic cylinder.The outer oil cylinder (1) of supercharging is the single casing oil hydraulic cylinder.
During work, start inner cylinder (6) earlier, hydraulic oil is from closing filler opening (14) soon by closing hydraulic pressure cavity (5) the generation pressure that the left oil circuit of piston rod (11) (18) enters charged piston bar bottom soon.Close piston rod (11) soon because of being subjected to the restriction of the outer cylinder cover (17) of hydraulic pressure, hydraulic oil only may order about charged piston bar (7), charged piston (9) moves downward.Meanwhile, start working with the liquid-filling valve (not shown) that liquid-filling valve flange (12) is connected, oil cylinder epicoele (10) oil-feed outside the supercharging that forms the space enters to avoid air.After charged piston bar (7) puts in place, restart the outer oil cylinder of supercharging, hydraulic oil enters oil cylinder epicoele (10) outside the supercharging from supercharging hydraulic fluid port (16), increases charged piston bar delivery pressure, reaches the purpose of supercharging.
When charged piston bar (7) needs return, close other oil circuits, start and close piston rod the right oil circuit (19) soon.The last hydraulic pressure cavity (3) that makes hydraulic oil enter inner cylinder (6) from filler opening (13) by right oil circuit (19) realizes return because of the pressure of oil forces charged piston bar (7) to move upward.
Because of the outer oil cylinder of supercharging is the single casing oil hydraulic cylinder, supercharging outer oil cylinder cavity of resorption is not oil-feed all the time, even sealing part (2) has small leakage, also can leak into fuel tank by drain tap (4), can not leak.
In sum, the utility model compared with prior art has the following advantages:
1, hydraulic oil pollution Workplace situation can not take place take place, be conducive to keep the safety in production, Carry out production strictly in line with rules and regulations.
2, only need start small oil tank during pressure release, need not to start large tank, reduce energy consumption, Save the time, improved efficient.

Claims (1)

1, a kind of Leakless combined oil cylinder, comprise outer oil cylinder (1) of supercharging and inner cylinder (6), inner cylinder (6) is located in the piston thick stick (7) of the outer oil cylinder of supercharging, fixedly connected with the outer cylinder cover (17) of pressurization hydraulic in piston thick stick (11) outer end of closing soon in the inner cylinder, it is characterized in that in inner cylinder (6), being provided with two working hydraulic pressure chambeies (3), (5), establish an oil circuit (19) again closing piston rod (11) soon, this oil circuit is connected with last hydraulic pressure cavity (3) in the inner cylinder, and the outer oil cylinder of supercharging is the single casing oil hydraulic cylinder.
