Background technique
The oil cylinder of plastic product molding machine can be seen in by being not limited to the following patent that exemplifies; the ZL01244534.7(moving-mold mechanism), the folding mould oil cylinder of ZL01244535.5(architecture advances), the matched mould locking mechanism of ZL200420027711.X(plastic hollow formation machine) and the matched mould locking mechanism of ZL200920035666.5(hollow plastic molding press), etc.
The oil cylinder post of oil cylinder and the sealing problem between the oil cylinder head always receive the concern of industry, because can only relying on seal ring, being sealed and matched between oil cylinder post and the oil cylinder head embody, and seal ring be subjected to self material factor, aging action, fluid corrosion factor and and the oil cylinder post between friction factor etc. and sealing effect is degenerated gradually, and even lose sealing effect.Especially, even if consummate manufacturing and mounting technology more also is difficult to guarantee the lasting sealing effect between oil cylinder post and the oil cylinder head, so the leakage of hydraulic oil fluid objectively can't avoid, and only is that matter of time is different with degree.
The achievement part of " leakage preventer of porous oil cylinder " that Chinese invention patent application publication No. CN101943194A recommends is to prolong oil cylinder working life, but complex structure." hydraulic press cylinder of leakage loss oil gathering-device is housed " that utility model patent notice of authorization CN2878761Y provides, this patent is to offer annular oil storage tank at cylinder cap, is drawn by the fluid that spill port will be collected in the annular oil storage tank.But because the structure of the hydraulic press cylinder that the power source of plastic molding machine is cylinder structure and CN2878761Y to be introduced is far from each other, thereby do not have referential meaning.
In view of above-mentioned prior art, the applicant has done useful design, and technological scheme described below produces under this background
Summary of the invention
Task of the present invention is to provide a kind of and helps that fluid that the matching part between oil cylinder post and the oil cylinder head is leaked is convenient to be collected and the leakage oil gathering-device of the oil cylinder that plastic molding machine simple in structure is used.
Task of the present invention is finished like this, the leakage oil gathering-device of the oil cylinder that a kind of plastic molding machine is used, described oil cylinder comprises cylinder tube, with the fixing oil cylinder head of an end of cylinder tube be arranged in the oil pocket of cylinder tube and oil cylinder post that be slidingly matched with the oil cylinder head cavity of oil cylinder head, wherein, sidepiece at the oil cylinder head is provided with the oil nozzle interface that communicates with the oil cylinder head cavity, the oil cylinder head cavity communicates with oil pocket, inwall at the oil cylinder head cavity is embedded with seal ring, oil cylinder post and seal ring are sealed and matched, be characterised in that: on the inwall of described oil cylinder head cavity and offering a remittance oil groove that is used for being collected in the leakage fluid that the oil cylinder post wanders from the oil cylinder post when stretching out the oil cylinder head cavity corresponding to the top of described seal ring around the circumferencial direction of the inwall of oil cylinder head cavity, and on the oil cylinder head, also be equipped with the oil-collecting joint that a fluid that is used for converging oil groove is drawn, communicate by the oil duct that draws that is opened on the oil cylinder head between this oil-collecting joint and the remittance oil groove.
In a specific embodiment of the present invention, on the inwall of described oil cylinder head cavity, also be provided with a dust ring, this dust ring cooperates with described oil cylinder column sealing, and this dust ring is between described remittance oil groove and described seal ring.
In another specific embodiment of the present invention, the position of described oil-collecting joint on described oil cylinder head is lower than the position of described remittance oil groove, and the described oil duct that draws is from converging oil groove towards the oil-collecting tilt of joint.
In another specific embodiment of the present invention, described oil-collecting joint comprises oil outlet and restriction nut, and oil outlet is connected with described oil cylinder head thread, and communicates with the described oil duct that draws, and is provided on the oil outlet 41 and limit nut thread.
One of technique effect of technological scheme provided by the invention, when the oil cylinder post stretched out the oil cylinder head cavity of oil cylinder head, the fluid that produces because of seepage just dropped down and falls within the remittance oil groove, draws from the oil-collecting joint through drawing oil duct, thereby can not pollute plastic article because of seepage; Two, help to alleviate the harsh processing request to oil cylinder; Three, overall structure is terse and can increase hardly the holistic cost of oil cylinder.
Description of drawings
Fig. 1 is the embodiments of the invention structural drawing.
Embodiment
See also Fig. 1, provided cylinder tube 1, according to common practise, cylinder tube 1 has an oil pocket 11, be that the upper end of shown position state is fixed with an oil cylinder head 2 at an end of cylinder tube 1, this oil cylinder head 2 has oil cylinder head cavity 21, and this oil cylinder head cavity 21 communicates with oil pocket 11, is equipped with an oil nozzle joint 22(who communicates with oil cylinder head cavity 21 at the sidepiece of oil cylinder head 2 and also can claims to pass in and out oily joint).On the inwall of oil cylinder head cavity 21 and be provided with one group of seal ring 211 corresponding to the position that is sealed and matched mutually with oil cylinder post 3 with the interval state, in the present embodiment, although illustrated that the quantity of one group of seal ring 211 is three, whereby quantity and limit technological scheme of the present invention.When illustrated piston column 3 be placed in oil pocket 11 interior after and when matching with oil cylinder head 2, aforesaid seal ring 211 just is sealed and matched with oil cylinder post 3.
Please continue to see Fig. 1, on the inwall of aforesaid oil cylinder head cavity 21 and offering a remittance oil groove 212 that is used for collecting the leakage fluid that oil cylinder post 3 wanders from oil cylinder post 3 when stretching out oil cylinder head cavity 21 corresponding to the top of one group of seal ring 211 around the circumferencial direction of the inwall of oil cylinder head cavity 21, this remittance oil groove 212 also can be described as oil storage grooves, and on oil cylinder head 3, also be equipped with the oil-collecting joint 4 that a fluid that is used for converging oil groove 212 is drawn, draw oil duct 23 perforations by being opened on the oil cylinder head 2 between this oil-collecting joint 4 and the remittance oil groove 212.
By shown in Figure 1, on the inwall of aforesaid oil cylinder head cavity 21, also be embedded with a dust ring 213, this dust ring 213 is converging between oil groove 212 and the seal ring 211.
Because the position of aforesaid oil-collecting joint 4 on oil cylinder head 2 is lower than the position of remittance oil groove 212 in oil cylinder head cavity 21, therefore draw oil duct 23 towards the direction inclination of oil-collecting joint 4.
Oil-collecting joint 4 comprises oil outlet 41 and restriction nut 42, and oil outlet 41 screws on oil cylinder head 2 and with drawing oil duct 23 with thread fiting mode and communicates, and limits nut 42 and screws on oil outlet 41, is used for limiting oil nozzle 41.Preferably, under the use state, connect a not shown oil pipe at the end of oil outlet 41, focus on so that the fluid that oil outlet 41 is drawn is introduced container.
When oil cylinder is in running order, be in the process of the oil cylinder post 3 oil cylinder head cavity 21 that leans out again and again retraction oil cylinder head 2, ooze out fluid in the matching gap of seal ring 211 and oil cylinder post 3 and drawn together by dust ring 213, fall to dropping down to converging oil groove 212, through drawing oil duct 23 and oil-collecting joint 4 is drawn.
In sum, technological scheme provided by the invention has remedied the shortcoming in the prior art, has finished the invention task, has embodied the technique effect described in the superincumbent technique effect of the claimant hurdle, and can yet be regarded as is a ultimate attainment technological scheme
