The specific embodiment
Integral body is designed to operation anesthesia needle 16 in injection moulding apparatus (further not illustrating) with 10 movement devices of representing among Fig. 1.This injection moulding apparatus is used for making moulded parts from flowable masses (for example molten plastic).For this reason, below the distribution plate (not shown), be provided with several pins valve nozzles (not shown equally).They flow to separable mould insert (not shown equally) with molten plastic to be processed, and its casting opening is closed pin 16 and periodically opens and close.Distribution plate top has to open establishes plate 12, and this is established plate and is provided with roughly rectangular depressed part or recessed crack 13 to hold movement device 10.
In order to operate the anesthesia needle 16 of needle valve nozzles simultaneously, so be provided with lifting element 20, fixing at least two anesthesia needles 16 on this lifting element 20.For example, lifting element 20 is designed to rectangular slab, it is parallel to open establishes plate 12, and connect with action element 30 in the longitudinal side, this action element 30 is along vertically supporting movably of first direction R1, wherein, this action element 30 is converted into this lifting element 20 moving along the second direction R2 that extends transverse to first direction R1 along moving of first direction R1.For this reason, lifter plate 20 sides respectively have two sliding members 21, and they are the parallel sliding guiding in action element 30.This action element 30 is provided with each two for this reason and obliquely establishes the groove 40 that plate 12 extends in opening in its side towards lifter plate 20, this groove holds sliding members 21 with little movement clearance.
The guiding of in guiding device 90, sliding in depressed part 13 inside of control rail 31, and be connected with driver 80 via common pushing member 82 and adapter 86 (invisible among Fig. 1).This driver 80 preferably is fixed on to open and establishes outside the plate 12.Wherein adapter pass an opening or recessed crack (not shown) distolateral pass to open establish plate 12.Driver 80 can be electronic, pneumatic or fluid pressure type is adjusted driver or adjusted motor, the operation of its preferred controlled electronic circuit (not shown equally).The connecting portion that the contiguous block (Kulissenstein) 88 of cross section T shape constitutes between pushing member 82 and the adapter 86, this contiguous block similarly needn't utilize instrument and form fit ground embedding pushing member 82.For this reason, this pushing member is provided with space 89.For contiguous block 88 is remained on the adapter, be provided with holding pin 87.
Each controls rail 31 has hook-like ends 33 in drive-side, and this end can be chimeric by side direction and pushing member 82.This pushing member has two stairstepping ends 83 for this reason, and they are held to form fit by the hook 33 of this control rail 31 (it perpendicular to first direction R1 inwardly towards).So cause a kind ofly to be fixedly coupled all the time along first direction R1, this connection can be along unclamping perpendicular to the direction of this first direction R1.Therefore the member 31,82 of action element 30 can at any time promptly assemble and dismantle (for example when using the lifter plate 20 of long and/or broad).When mounted, can not must instrument element 31,82 is pegged graft mutually simply, wherein, they constitute the setting of U-shaped under assembled state, and firmly connection mutually.The operation of whole movement device 10 is extremely simple; Installation cost is very cheap.
The fitting pin 96 that is not shown specifically is used for guide rail 91 accurately is orientated in depressed part 13.They firmly are inserted in to open and establish at the end 14 of plate 12, and are cooperated in guide rail 91 and hold exactly by (the not detailed hole that illustrates).
Design among the optional change embodiment shown in Fig. 3 and Fig. 4, this guide rail 91 has two sliding panels 93 at it on the side 92 of control rail 31, and they are preferably made with the material coating of self-lubrication or by this material.
As can be seen, constitute U-shaped grafting frames along action element 30 and the control rail 31 and the pushing member 82 of direction R1 guiding, this grafting frame surrounds lifter plate 20 from the side with little movement clearance, and the guiding of should the grafting frame sliding in guiding device 90.For further few the sliding friction in movement device 10, so control rail 31 tops and below are provided with sliding panel 35, this material coating is made or used at least in part to its material by self-lubrication.The sliding panel 35 of control rail 31 constitutes sliding members together with the sliding panel 93 of guide rail, moves around thereby this action element 30 can only take very little power.In addition or alternatively, rib or ball bearing, needle bearing or roller bearing can be designed to this sliding members 35,93 to slide.But they also can be the part of ball bearing, needle bearing or roller bearing.
Also illustrate as Fig. 1, other can be controlled rail 131 and be connected on the control rail 31.Another lifting element 120 and open is established plate 12 abreast between control rail 131, and this lifter plate 120 is connected on first lifter plate 20 as the rectangular slab with same widths, and other anesthesia needle 116 is fixed on the described lifter plate 120.Described two boards 20,120 longitudinally is co-located between the stopper section 60,62 of fixed-site.
For other control rail 131 is connected on the control rail 31, so the end 133 towards driver 80 of the end that deviates from pushing member 82 34 of control rail 31 and other control rail 131 similarly is designed to hook-type, wherein, the hook end 133 of the hook end 34 of this control rail 31 and other control rail 131 is designed to identical shaped, and each is perpendicular to the direction of first direction R1 directed in opposite.At this, hook 34,133 mutual form fit ground engage, thereby have firm connection all the time along first direction R1, but this connection can be unclamped along the direction perpendicular to this first direction.
So control rail 31,131 can be connected to each other rapidly and simply by hooking simply or inserting via terminal 34,133.Therefore how many time movement device 10 can not take and at any time expand an other lifter plate 120 again, and its method is with other control rail 131 hooks or is connected on the existing control rail 31.This other control rail is connected with driver 80 via control rail 31 and pushing member 82, therefore the driver element that need not add.This point also has utmost point favorable influence to the instrument cost.
This other lifter plate 121 as lifter plate 21, respectively has two sliding members (not shown) in the side, they slide abreast in control rail 131 and guide.At this, control rail 131 is provided with each two and obliquely establishes the groove 140 that plate 12 extends in opening in its side towards lifter plate 120, and they are to hold sliding members until very little movement clearance.This other control rail 131 is equally with the vertically movably mode guiding of sliding between the guide rail 91 of two fixed-site of guiding device 90.
If driver 80 periodically moves back and forth frame 30 along first direction R1, then moved up and down along second direction R2 (it is preferably perpendicular to direction R1 and extends) by the sliding members of guiding in the skewed slot 40,140 of control rail 31,131 at the lifter plate 20,120 that forces guiding between the stopper section 60,62.Therefore lifter plate 20,120 (its end face (not being shown specifically) flatly leans on mutually) is with settling anesthesia needle 16,116 thereon to do the synchronization lifting motion, and wherein, all closure members 16,116 side by side and with identical adjustment power are operated all the time.
In order to make this U-shaped action element 30 time between lifter plate 20,120 and guiding device 90, be unlikely inclination in running, be provided with and force guide member 50 so be parallel to guide rail 91 ground, it is guided action element 30 extraly along direction R1.This forces guide member 50 to be preferably designed to linear guide.It respectively has a microscler guide element 52 on driver 80 bilateral symmetry ground, and this guide element 52 forces guiding in supporting member 54.
For example, guide element 52 is a round pin, and it utilizes bolt 53 to be fixed on the pushing member 82.In order to ensure will selling 52 vertical orientated exactly on the end face 84 of driver 80 at pushing member 82, so blind hole (not being shown specifically) is established in the pushing member 82, this blind hole will be sold 52 and be cooperated and hold exactly.This pin 52 is parallel to direction R1 all the time and an end face 15 towards driver 80 of establishing plate 12 is passed in projection.
For example, each supporting member 54 is ball-recirculation sleeve (Kugelumlaufbuchse), and its distolateral insertion is opened and established in the plate 12 and hold the guide pins 52 of being attached troops to a unit with as far as possible little movement clearance respectively.Guide pins 52 is in the guiding exactly always of this ball-recirculation sleeve 54 (they are parallel to direction R1 orientation equally) inside, and therefore mobile frame 30 must move along direction R1 by compulsion exactly.Therefore shifter 30 is farthest got rid of with respect to lifter plate 20,120 and/or with respect to the inclination of guide rail 91.Movement device 10 is guaranteed frame 30 accurately and equably guiding in guiding device 90 always.
In the embodiment of Fig. 3 to Fig. 5, the guide member 50 relative drivers 80 that force that are designed to linear guide have guide element 52 in central authorities, the guiding of sliding in supporting member 54 of this guide element.This supporting member 54 is made of two guide rail 56, and guide rail 56 is placed in to open and also firmly is screwed on this place at the end 14 of establishing plate 12.
Particularly as shown in Figure 5, guide element 52 is designed to microscler flat element and is integral with pushing member 82.It is positioned at pushing member 82 central authorities exactly, and therefore central between control rail 31.Side channel 57 lubricants in flat element 52 both sides, so the sliding friction in the supporting member 54 minimizes.Therefore whole device needn't be safeguarded as far as possible.
In order lifter plate 20,120 to be done limit and to be had the elevating movement of reproducibility (reproducible) all the time, so pushing member 82 utilizes the stopper section restriction along moving of first direction R1.Open and establish plate 12 formations first stopper section, and should constitute second stopper section near the stopper section 60 of driver 80.The adjustment stroke that distance between distolateral wall 15 and the stopper section 60 has been preset pushing member 82 and therefore also preset control rail 13,131, so they can move back and forth between the position of two qualifications at least.Lifter plate 20, decide according to the obliquity of groove 40,140 and sliding members, do the elevating movement that limits accordingly, wherein, when if for example anesthesia needle 16,116 will take different sealings and release position to, then utilize driver 80 also can on purpose start the centre position.
Releasable socket connection between the member 31,82 and 82,88 and 31,131 has advantage, that is: movement device 10 can be installed in the recessed crack 13 of baffle plate 12 by the top rapidly and successfully.Have only stopper section the 60, the 62nd, be inserted in the depressed part 13.Therefore 10 parts by a little tool simple geometric shape of whole movement device constitute.It can be installed by the utmost point simply, and extendible at any time.Otherwise, lifting element 20,120, control rail 31,131, pushing member 82 and guide rail 91 can be dismantled from opening to establish the plate 12 rapidly and successfully at any time, so that for example with component replacement defective so that can change anesthesia needle 16,116, or do other maintenance work.
Anesthesia needle 16,116 by on put in the lifter plate 20,120, this lifter plate is provided with hole (not being shown specifically) for this reason.Each pin 16,116 is distolateral in the zone of lifter plate 20,120 has screw thread, described being threaded in the roughly rectangular holding plate (invisible).Adjust nut (not being shown specifically equally) pin 16,116 is fixed with respect to holding plate, holding plate entirely is located on the lifter plate 20,120.So pin 16,116 can individually be adjusted length with respect to lifter plate 20,120 along second direction R2.
Each holding plate is arranged in a space (not shown equally), and it highly is close to the height be equivalent to holding plate just, and its outside dimension is greater than the outside dimension of holding plate, so holding plate can radially motion in this space.The cover plate 25 that utilizes bolt 26 to be fixed on the lifter plate 20 remains on holding plate in the space.Therefore holding plate is settled between lifter plate 20,120 and cover plate 25 with the little movement clearance of trying one's best along the axis direction of anesthesia needle 16,116, and therefore whole pins 16,116 can take detent position and open more all the time exactly to.Otherwise this holding plate radially then is the floating ground supporting, so pin 16,116 departing from passage of heat nozzle can be cancelled.Utilize the design of holding plate in addition, make pin 16,116 with respect to lifter plate 20 anti-settings rotationally.
Pin 16,116 is adjusted nut 18 projections with it and is passed cover plate 25 in the past.But in order to make the terminal unlikely outstanding lifter plate of pin 20,120 outer too many, so holding plate and cover plate 25 be positioned at depressed part 24, its by on establish in the lifter plate 20,120.So, the structure height of movement device 10 keeps very little.
Central authorities between depressed part 24, lifter plate 20,120 constitutes a central fovea crack 70 (see figure 1)s, and it establishes continuity in the plate 12 with identical interior diameter opening.Recessed crack 70 is used to make flow channel, dispense arm or analog, particularly machine nozzle or casting sleeve (not shown), by, their are supplied with institute's plastics materials to be processed to be positioned at and establish the distribution plate of plate 12 belows.The interior diameter in recessed crack 70 (not being shown specifically) is so set, and makes lifter plate 20,120 unhinderedly to move.There are recessed crack 70 (see figure 3)s at each lifter plate 20 centers, and this recessed crack is established continuity in the plate 12 with identical interior diameter opening.This recessed crack 70 also is used to make flow channel, dispense arm or analog, particularly machine nozzle or casting sleeve (not shown), by.
The cover plate (not shown) constitutes the closure of movement device 10, and described cover plate entirely is located on the guide rail 91, and utilizes bolt (not shown equally) fixed thereon.Cover plate 19 is guaranteed all socket connections, and preferred flushes with opening the upside of establishing plate 12, so movement device 10 can projection exceed and establishes outside the plate 12.Or rather, device 10 almost completely is incorporated into to open and establishes in the plate 12, and this structure height to instrument has utmost point favorable influence.Have only driver 80 to place to open and establish on plate 12 outsides, but this point is to not influence of structure height.
In the embodiment of Fig. 1 and Fig. 2, on lifting element 20,120, fixing 32 anesthesia needles 16 altogether.But undoubtedly can increase or reduce the number of anesthesia needle 16, its method is that lifter plate 20,120 is done corresponding design.For given tool-face is made full use of as the best, can make several mould inserts (Formeinsatz) and therefore make the very adjacent setting of near-earth of several pins valve nozzles.
Also can consider two laterally adjacent settings of movement device 10.For this reason, open and to establish plate 12 and be provided with two adjacent depressed parts 13 or be provided with a common depressed part, so the control rail 31,131 and the guide rail 91 of each movement device 10 are adjacent one another are abreast.
The invention is not restricted to the foregoing description, but can change in many ways.Therefore alternatively or extraly, the guide element 52 that forces guide member 50 directly can be fixed on the control rail 31.At this, when needs, this guide element is a kind of rectangle pin.Supporting member 54 can be designed to the sleeve of self-lubrication, and its cooperation is held pin 52 exactly and with the little movement clearance of trying one's best.
The end that deviates from driver 80 (not being shown specifically) of control rail 131 in addition can similarly be designed to hook-type, so that can connect other control rail.It is identical with hook end 33,34,133 shapes that these hook ends also are designed to, and make up like this, makes to produce the connection of tension all the time along first direction R1, and can unclamp along the direction of vertical this first direction.
Therefore whole movement device 10 can be designed to construct the case system, described movement device can individually and neatly make up with a little primary element 20,30,50,120,90.All members can promptly be connected to each other by simply hooking or inserting, and unclamp when being necessary again.At this, control rail 31 both sides are provided with hook-like ends, and this point makes manufacturing simpler.Therefore movement device 10 can not spent big time and at any time expands or cooperate different demands to change.
Characteristics that all disclose in claims, specification and accompanying drawing and advantage comprise that CONSTRUCTED SPECIFICATION, space are provided with and method step, can individually or make various combination and implement, and everything all within the scope of the present invention.
