Technical field
The present invention relates to a kind of lead-screw drive mechanism that is used for injection molding machine, comprise a leading screw, a feed screw nut, a lubricated district and the seal area between leading screw and feed screw nut.
Background technique
This class lead-screw drive mechanism is also referred to as the ball screw driving mechanism, for example is used for making the elbow-bar mechanism of injection molding machine closed side (matched moulds side) to move.
To this, JP 2003-011196 discloses a kind of lead-screw drive mechanism that is used for the injection molding machine injection side.In the document, described and be arranged in two seal arrangements that point to leading screw on the feed screw nut.Wherein, these two seal arrangements constitute a seal area separately, form the lubricated district of lead-screw drive mechanism between them.Lubricant oil enters among the lubricated district between leading screw and the feed screw nut by the supply line in the feed screw nut.Discharge conduit equally also is arranged among the feed screw nut.Although the lubricant oil that still flows out for existing the seal oil device is provided with an oil drip pan that is used to take in the machine oil of drippage below lead-screw drive mechanism.
In having the oil lubrication type lead-screw drive mechanism of seal arrangement, the problem of existence is: because speed and load are very high, although taked the seal oil measure, lubricant oil also can flow out from lubricated district, and the surrounding environment of directly making injection molding machine dirty.For preventing this situation, for example adopted the in addition measure of sealing cover of whole lead-screw drive mechanism, but this measure is very complicated and expensive by prior art is known.
Summary of the invention
Therefore the objective of the invention is to, a kind of lead-screw drive mechanism that compared with prior art is improved is provided.Especially, should be so that lubricant oil still less flow out from lead-screw drive mechanism, thus stop lubricant oil to drip as far as possible from leading screw.Uncomplicated seal oil device on a kind of simple, structure that is used for lead-screw drive mechanism will be provided in addition, and a kind of cleaning and be suitable for the lead-screw drive mechanism that the cleanroom uses.Should be able to utilize lubricant oil again more in addition, and find and a kind ofly lubricant oil is fed to measure among the oiling agent zone with plain mode.
For the lead-screw drive mechanism with the described feature of claim 1 preamble, this purpose is achieved in the following manner: be provided with in seal area: one is positioned at lubricated Qu Yiduan, forms lubricated border, district and is close to the first seal oil device on the leading screw; One be located at lubricated district same side with the first seal oil device the samely, be arranged on the first seal oil device lubricated district dorsad that side and be close to the second seal oil device on the leading screw; An and lubricant oil drainage port between the first seal oil device and the second seal oil device.
Therefore, different with JP 2003-011196, the lubricant oil drainage port is not to be arranged among the lubricated district, but among seal area, like this, still the second seal oil device that the lubricant oil that flows out from lubricated district although exist the first seal oil device just can be arranged in thereafter the same seal area scrapes off, and is derived by the lubricant oil drainage port.For this is further improved, the 3rd and more lubricating oil seal arrangement and lubricant oil drainage port can be set in seal area.Thereby, adopting the present invention, even if lubricant oil flows out from leading screw in the first seal oil device back, still can implement further lubricant oil to be scraped off and derives from leading screw pointedly.
According to a kind of embodiment of the present invention, can stipulate: be fixed on the feed screw nut to major general's first seal oil device; Preferably implement flexible program according to another, can stipulate: also the second seal oil device is arranged on the feed screw nut, but it is to be fixed on the feed screw nut with respect to first seal arrangement in that side of lubricating the district dorsad.The seal area preferred arrangements is among the zone of the sensing elbow-bar mechanism of lead-screw drive mechanism.So just make the lubricated district of seal oil device between leading screw and feed screw nut that win, and the second seal oil device that plays frizing (retaining oil) effect is among the curved bar side is arranged in lead screw gear.
If the seal oil device is arranged on the feed screw nut, then preferably stipulate: the lubricant oil drainage port is the delivery port in feed screw nut.For example, among lubricant oil can drip or flow out to the shell zone of encirclement from this delivery port.But also the lubricant oil drainage port only can be designed to the free space between the first and second seal oil devices in principle.
The seal oil device is close on the leading screw by the slim lubricant film that is attached between seal arrangement and leading screw on the leading screw.Can prevent from like this to produce too big frictional heat because of the friction between the steel of the rubber constituent element of seal arrangement and leading screw.Owing to, needn't worry drippage, thereby also needn't worry to be made dirty in the lead-screw drive mechanism outside at slim lubricant film and the adhesion between the leading screw.Therefore for the present invention, equally also can use wording frizing district (Abstreifbereich, retaining oil is distinguished) and oil wiper (Abstreifer, oil strainer) substitutes wording seal area and seal arrangement, although seal arrangement is arranged simultaneously, also some lubricant oil flows out (in desired mode) slightly.So regulation particularly preferably: the conformable region that makes the seal oil device is suitable with the cross-sectional profiles of leading screw, preferably passes through the frizing lug boss.The cross-sectional profiles of leading screw is made of teeth portion and screw thread slot part.
Generally speaking, though lead-screw drive mechanism of the present invention can be used among the zones of different of injection molding machine, preferably this lead-screw drive mechanism is used for the closed side (matched moulds side) of injection molding machine.At this, preferred whole driving mechanism can move in this wise, promptly, rotatably drive feed screw nut, and can make the leading screw translational motion by feed screw nut, described leading screw links to each other with the crosshead of the elbow-bar mechanism of injection molding machine closed side, and elbow-bar mechanism makes the moveable die clamping plate move with respect to end plate.

Embodiment
Accompanying drawing 1 is depicted as the most sectional view of injection molding machine closed side.Elbow-bar mechanism 9 shown in the figure is in outwardly directed position, thereby is exactly to be in closure (matched moulds) or injection position.The leading screw 2 of translational motion drives this elbow-bar mechanism 9 via crosshead 8 and leave the moveable die clamping plate motion that end plate 10 (and return) is not drawn in figure.By driving leading screw 2 translational motions own around the feed screw nut 3 of leading screw axis A rotation driving.At this, realize this movement conversion by the rolling element 31 of ball in the meshing screw thread slot part 22 between leading screw 2 teeth portions 21 or roller shape.Owing to frictional heat can occur with this, thereby will should lubricated district S supplying lubricating oil 7 by being configured in that lubricant oil supply line 12 among the leading screw 2 gives.Preferably through the lubricant oil 7 of supercooling by lubricant oil supply line 12 with extend substantially transversely to supply orifice 30 that leading screw axis A constitutes and enter among the lubricated district S.In order to prevent that lubricant oil 7 is from this lubricated district S or flow out from the whole zone of lead-screw drive mechanism 1, on the one hand be provided with a leading screw sleeve 20, be provided with on the other hand according to seal oil device 4 of the present invention and 5 and disposed therein lubricant oil drainage port 6.Shown in this accompanying drawing 1, when leading screw 2 moves right, make most of lubricant oil 7 remain among the lubricated district S by seal oil device 4.But still have lubricant oil 7 and continue to penetrate into forward among the seal area D, therefore there be second seal oil device 5 to be close on the leading screw 2 there, thereby prevent that most of lubricant oil 7 from continuing to flow out (in other words being that it is scraped off), and can discharge by the delivery port in the feed screw nut 36.The lubricant oil 7 of Pai Chuing is caught by the shell that is fixedly linked with end plate 10 of lead-screw drive mechanism 1 therefrom, and can be derived via the discharge conduit of not drawing among the figure 15 by lubricant oil current drainage aperture 14.Shown in this accompanying drawing 1, a drip tray 11 can be set, described drip tray has one and links to each other with crosshead 8 and slight inclination or the 11a of first portion that has a down dip, and has a second portion 11b who is arranged on the end plate 10.When whole elbow-bar mechanism 9 comprises that crosshead 8 and leading screw 2 are when opening (die sinking) direction just to left movement, also can make the 11a of first portion of drip tray 11 move and " passing " this end plate, enter among the zone of drip tray 11 second portion 11b top towards end plate 10 directions.If disposed drip tray 11, then can be set being used for from the discharge conduit 15a of the leakage of oil of shell 13 drippages, because can directly take in leakage of oil in drip tray 11 of right side.Although the discharge conduit 15a on right side is arranged, to be on the safe side, still drip tray 11 can be set, may prevent the injection molding machine of making dirty from shell 13 or the lubricant oil that flows out or drip from leading screw 2 so that take in.
In accompanying drawing 2, the zone that separates that lubricated district S and seal area D are presented as lead-screw drive mechanism 1 once more, wherein, lubricant oil drainage port 6 is configured between the first seal oil device 4 and the lubricated dorsad seal oil device of distinguishing 5.Two seal oil devices 4 contact with leading screw 2 with its conformable region that adapts to leading screw 2 cross-sectional profiles with 5.At this, the frizing lug boss 32 of conformable region accurately is engaged in the screw thread slot part 22 ordinatedly.Add towards the moveable die clamping plate subsequently a cover plate 16 with leading screw 2 break-through apertures 17 is fixed on the shell 13.Perhaps, also this cover plate 16 can be directly fixed on the end plate 10.
In lead-screw drive mechanism 1, need lubricant oil 7 among the not only lubricated district S, and especially in the zone of rolling bearing 33, also need lubricant oil in the swivel bearing district of feed screw nut 3.Lubricant oil 7 arrives this zone via lubricated district S by the connecting passage 26 of going to rolling bearing 33 from lubricating pipe 12, and forms oil sump 34 there.Seal by 24 pairs of these zones of two feed screw nut seal arrangements.Because lubricant oil current drainage aperture, left side 14b (difference to that indicated in the drawings) is to design in side direction and in shell 13 to improve slightly, therefore can keep stable lubricant oil level in oil sump 34.Can in regional 35 scopes, drive whole feed screw nut 3 by belt gear 25 by the motor of not drawing among the figure.Reference character T represents to be used for detecting the sensor of lubricating oil temperature, it can be arranged among the oil sump 34.
Accompanying drawing 3 also schematically illustrates lubricant circulates loop K.Wherein, lubricant oil 7 enters the lubricated district S by lubricating pump 19 that is driven by motor M and the supply line 12 that comprises supply boring 30 from oiling agent collecting container 18.In supply line 12 zones lubricating oil filter 28 and lube oil cooler 29 can be set, for example the lubricating oil temperature of measuring according to sensor T is controlled or is regulated it.Not only can but also can derive lubricant oil subsequently by the lubricant oil current drainage aperture 14a shown in lubricant oil drainage port 6 and the right side by lubricant oil current drainage aperture, the left side 14b at oil sump 34 places.Have discharge conduit 15a and 15b to turn back to lubricant oil collecting container 18 respectively from two lubricant oil current drainage aperture 14a and 14b, lubricant oil 7 also can drop onto the drip tray 11 from lubricant oil current drainage aperture, right side 14a.
Can find out also in this accompanying drawing 3 leading screw 2 time is being how to enter among the space that is surrounded by leading screw sleeve 20 towards opening the direction motion.This can be seen that the supply boring 30 of supply line 12 no longer directly is passed among the lubricated district S.Can control or regulate the lubricant oil supply according to this situation, making only could supplying lubricating oil 7 in the close position of operating position.Realize the air balance in spaces in the leading screw sleeves 20 in order to pass through connecting passage 26, the air supply aperture 23 that disposes a band air-strainer 27, thus can squeeze or suction air according to the position of leading screw 2.
