Description
Technical field
The utility model is related to high-voltage oil cylinder technical field of structures, in particular to a kind of high-pressure minis of novel mounting structure
Oil cylinder.
Background technology
High-pressure mini oil hydraulic cylinder is to install relevant piston ring and sealing ring respectively on piston at present, makes the piston of piston
The urgent state for being sealed at inboard wall of cylinder block and maintaining high pressure sealing of ring, passes through piston ring and inboard wall of cylinder block to avoid high pressure oil seepage flow
Between.High-pressure mini oil cylinder is important component fervent in mould, and fervent system and the integrated of mold are wanted with cooperation in mould
Ask extremely stringent, otherwise mold will appear many serious problems in process of production, therefore, structure to high-pressure mini oil cylinder and
The precision requirement of installation is very high.
A kind of minitype high voltage of the existing high-pressure mini cylinder structure usually as disclosed in Chinese patent CN204533041U
Oil cylinder, cylinder body are fixed in the mounting hole of template, and cylinder barrel is fixed in mode, and cylinder base opens up high pressure oil hole, and is arranged
External high-pressure oil pipe is connected to by High-pressure oil sealing with piston chamber；When installation, therefore, to assure that the leakproofness of cylinder base High-pressure oil sealing,
Otherwise oil cylinder easy oil leakage and break down, secondly by fixed ring by oil cylinder locking when in the mounting hole of template, need to strictly protect
The balance of oil cylinder locking is demonstrate,proved, otherwise because putting stroke inaccuracies cause notch is uneven even to make handspike damaged.Therefore, this structure is micro-
Type high-voltage oil cylinder is very high for installation precision requirement, and installation and debugging and maintenance are very troublesome.
In addition, when high pressure oil injects piston chamber, oil circuit residual air moment is compressed and crowded in piston and cylinder body
At the seal assembly of wall, and moment heats up, and with the perseveration of piston, seal assembly is caused to be influenced and quickly old by high temperature
Change.
Utility model content
The purpose of this utility model is to provide a kind of high-pressure mini oil cylinder of novel mounting structure so that high-pressure mini oil cylinder
Installation maintenance is easy.
To achieve the above object, technical solution used by the utility model is：
A kind of high-pressure mini oil cylinder of novel mounting structure, including the cylinder sleeve and piston that are slidably matched, cylinder sleeve bottom and work
Piston chamber is formed between plug, the bottom centre of cylinder sleeve is equipped with vertical perforative installation screw, further includes and installation screw tight fit
Lock-screw, the head of lock-screw downward, for locking onto template from bottom by cylinder sleeve, is equipped with connection in lock-screw
The oil circuit via of template oil circuit and piston chamber；Cylinder sleeve bottom surface around lock-screw periphery is also embedded with sealing ring.
Further, it is equipped between the periphery wall and cylinder sleeve of piston positioned at the guide ring of epimere and close positioned at the piston of hypomere
Sealing assembly；The bottom of piston is equipped with the cushion chamber of indent communicated with piston chamber, cushion chamber include from bottom to up and diameter successively
Big cylindrical section, conical section, roundlet shell of column and the vertex of a cone section reduced.The top of the cushion chamber is higher than piston seal component.It is described
Piston seal component includes O-ring and is placed on the seal wear-resistant ring of O-ring periphery.High pressure oil can depressurize simultaneously when entering piston chamber
Cushion chamber is preferentially entered, air is compressed to the top of cushion chamber step by step, and atmosphere temperature rising is smaller, and will not impact seal assembly,
The service life of seal assembly is long；Guide ring makes piston when increasing diameters of axle ratio without beat, and can make piston and cylinder sleeve
Gap smaller, oil cylinder bearing capacity is stronger.
Further, the head of the lock-screw is also arranged with sealed aluminum pad.
The advantageous effect of this programme is：The installation screw at cylinder sleeve center only need to be up locked from template bottom with lock-screw
Installation can be completed and ensure the balance of oil cylinder, installation and debugging are easy, in use, if there is the oil leak of cylinder sleeve bottom
When failure, only need to slightly tighten lock-screw can compress the sealing ring of cylinder sleeve bottom, safeguard simple.
Description of the drawings
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
Fig. 1 is the cross-sectional view of embodiment mesohigh oil cylinder.
Specific implementation mode
The utility model is further described below in conjunction with attached drawing：
With reference to a kind of high-pressure mini oil cylinder of novel mounting structure shown in FIG. 1, including the cylinder sleeve 1 and piston that are slidably matched
2, piston chamber 3 is formed between 1 bottom of cylinder sleeve and piston 2, the bottom centre of cylinder sleeve 1 is equipped with vertical perforative installation screw 11, also
Include the lock-screw 4 with 11 tight fit of installation screw, the head of lock-screw 4 downward, for being lock onto from bottom by cylinder sleeve 1
In template below mode, the oil circuit via 41 of connection template oil circuit and piston chamber 3 is equipped in lock-screw 4；Around lock-screw 4
1 bottom surface of cylinder sleeve of periphery is also embedded with sealing ring 12.Only 1 center of cylinder sleeve need to be up locked from template bottom with lock-screw 4
Installation screw 11 can be completed installation and ensure the balance of oil cylinder, and installation and debugging are easy, in use, if there is cylinder
When covering 1 oil leakage fault in bottom, only need to slightly tighten lock-screw 4 can compress the sealing ring 12 of 1 bottom of cylinder sleeve, safeguard simple.
A kind of preferred embodiment is equipped between the periphery wall and cylinder sleeve 1 of piston 2 under being located at the guide ring 21 of epimere and being located at
The piston seal component 22 of section；The bottom of piston 2 is equipped with the cushion chamber of the indent communicated with piston chamber 3, and cushion chamber includes under
Big cylindrical section 201, conical section 202, roundlet shell of column 203 and the vertex of a cone section 204 that supreme and diameter reduces successively；High pressure oil enters work
Cushion chamber can be depressurized and preferentially entered when filling in room 3, and air is by compression (because cushion chamber diameter reduces step by step) step by step to cushion chamber
