EJ tie-rod 72 is inserted through the bullport 65 of EJ crosshead 63, and EJ crosshead 63 moves forward and backward freely along EJ tie-rod 72.Also can for example, with many (2) EJ tie-rods 72 multiple bullports 65 be set accordingly.What can prevent EJ crosshead 63 take front and back as the rotation of axle.
The rearward end of EJ bar 68 is fixing by EJ plate 71, and the not shown products formed ejector member arranging on the leading section of EJ bar 68 and dynamic model 33 (with reference to Fig. 1) links.In the time that EJ bar 68 is advanced, products formed ejector member makes products formed from dynamic model 33 demouldings.Afterwards, in the time further making EJ bar 68 advance, products formed is transported to extracting position by products formed ejector member.After taking out products formed, in the time that EJ bar 68 is retreated, products formed ejector member turns back to original position.On EJ plate 71, also can fix many EJ bars.
Ejector member 70 is ejecting starting position standby in mold closing operation and matched moulds operation, after die sinking operation, advances to and ejects end position from ejecting starting position.Ejector member 70 eject starting position by decisions such as the shapes of dynamic model 33.After having taken out products formed by knockout machine, ejector member 70 turns back to and ejects starting position.
In addition, in order to shorten molding cycle, ejector member 70 also can start to advance in die sinking operation.
As shown in FIG. 1 to 3, EJ can also can be disposed in than the supporting 51 of EJ toggle on the position of dynamic model 33 by dynamic pressure plate 52.Make EJ can dynamic pressure plate 52, ejector member 70 is while advancing, EJ can dynamic pressure plate 52 and EJ toggle supporting 51 between interval shorten, the center line of EJ toggle arm 61 diminishes with the angle θ that the center line of EJ the first angle lever 62 becomes.Therefore,, along with advancing of ejector member 70, change as described below and eject characteristic.
In the time that ejector member 70 starts to advance from ejecting starting position, ejecting force sharply dies down.Afterwards, ejecting force changes hardly, but along with the front of ejector member 70 and then slowly die down.
And in the time that ejector member 70 starts to advance from ejecting starting position, the speed that ejects sharply accelerates.Afterwards, along with the front of ejector member 70 and then the speed that ejects slowly accelerate.
So, according to ejector member 70, the interval between can dynamic pressure plate 52 with respect to the position of dynamic model 33, i.e. EJ toggle supporting 51 and EJ changes the characteristic that ejects of liftout attachment 50.Ejecting while starting, the speed that ejects is compared with slowly and correspondingly ejecting force is stronger, the easy demoulding of products formed.After the demoulding, eject speed, and can promptly products formed be transported to extracting position.
EJ motor 66 (with reference to Fig. 5) is the drive source that EJ device 50 is worked.EJ motor 66 be for example disposed in can dynamic pressure plate 13 on.In addition, the equipping position of EJ motor 66 without particular limitation of, for example also can be disposed in EJ toggle supporting 51, EJ can dynamic pressure plate 52 etc. on.
Rotatablely moving of EJ motor 66 is transformed to rectilinear motion by EJ ball screw framework 67, and is delivered to EJ toggle mechanism 60.EJ ball screw framework 67 is for example by being fixed on the EJ ball-screw nut 67a in EJ crosshead 63 and forming with the EJ ballscrew shaft 67b that EJ ball-screw nut 67a screws togather.The rotating shaft 57 forwards extending coaxially from EJ ballscrew shaft 67b, rotates freely and can not advance and retreat and install with respect to EJ toggle supporting 51 via bearing Br etc.Rotating shaft 57 links via the connecting members such as band, belt wheel 56 and the output shaft of EJ motor 66.In the time that the output shaft of EJ motor 66 rotates, EJ ballscrew shaft 67b rotation, EJ ball-screw nut 67a, EJ crosshead 63 are advanced and retreat with respect to dynamic model 33.
In addition, the rotating shaft 57 of present embodiment links via connecting member 56 and the output shaft of EJ motor 66, but also can directly link with the output shaft of EJ motor 66.
When forward drive EJ motor 66, while making EJ crosshead 63 advance with respect to dynamic model 33 and EJ toggle mechanism 60 is worked, EJ can advance with respect to dynamic model 33 by dynamic pressure plate 52.On the other hand, when reverse drive EJ motor 66, while making EJ crosshead 63 retreat with respect to dynamic model 33 and EJ toggle mechanism 60 is worked, EJ can retreat with respect to dynamic model 33 by dynamic pressure plate 52.
Fig. 7 is the liftout attachment that represents one embodiment of the present invention with respect to the top view of installation method that can dynamic pressure plate.Fig. 8 is that then Fig. 7 represents the top view of liftout attachment with respect to installation method that can dynamic pressure plate.
As shown in Fig. 1～Fig. 6, can comprise by dynamic pressure plate 13: the main part 41 that dynamic model 33 is installed; Transmit the arm 42 of mold clamping force to main part 41 from mold clamping force generation mechanism 29; And the extension 43 that stretches out and be connected with arm 42 from main part 41.Main part 41, arm 42 and extension 43 for example can come one-body molded by casting etc.
For example, as shown in Figure 5, main part 41 forms by forming the plate-like portion 41a of installed surface of dynamic model 33 and the cylindrical portion 41b being arranged on plate-like portion 41a and face mould installed surface opposition side.The leading section of guide bar 53 is fixed on plate-like portion 41a.For lightweight, raising operability, cylindrical portion 41b also can have peristome in side.Be equipped with EJ plate 71 in the inside of cylindrical portion 41b, be fixed with EJ toggle supporting 51 at the rear portion of cylindrical portion 41b by bolt etc.
Arm 42 rearward extends from main part 41 (being specially cylindrical portion 41b).For example, as shown in Fig. 4, Fig. 6, be respectively provided with respectively a pair of arm 42 in the top and the bottom of main part 41, and as shown in Figure 1, rotate the end (for example end of toggle arm 22) of supporting freely toggle mechanism 20 via pin 47.On each arm 42, be formed with the patchhole that supply and marketing 47 is inserted.
For example, as shown in Figure 4, extension 43 can respectively respectively in the top and the bottom of main part 41 arrange one, and supports mutual opposed of a pair of arm 42 of mutual opposed of a pair of arm 42 of upside and downside.The side 43a of extension 43 has the part tilting with respect to matched moulds direction (being that mould opens and closes direction).The part tilting be plane in the present embodiment, but as long as with respect to matched moulds direction inclination, also can be curved surface.In the time of matched moulds, can suppress the bending of arm 42, and in the time of matched moulds, can reduce can dynamic pressure plate 13 strain.
For example, as shown in Figure 4, extension 43 can connect mutual opposed of a pair of arm 42.Extension 43 has the part of more towards main part 41 sides in front, more stretching out significantly from arm 42.
In addition, the extension 43 of present embodiment connects mutual opposed of a pair of arm 42, but also can not connect, and also can on each arm 42, respectively arrange one.In addition, the extension 43 of present embodiment flatly stretches out from arm 42, but also can from arm 42 upward or below stretch out.In the time of matched moulds, can suppress the bending of arm 42.
Can dynamic pressure plate 13 can have and insert space 44, by liftout attachment 50 when can dynamic pressure plate 13 installing, insert for the suspender 81 of at least a portion of the liftout attachment 50 of slinging in this insertion space 44.The part of being sling by suspender 81 in liftout attachment 50 is called to EJ assembly herein.EJ assembly for example by EJ toggle supporting 51, EJ can dynamic pressure plate 52, EJ toggle mechanism 60, EJ plate 71 and EJ tie-rod 72 form.
Suspender 81 is for example made up of the thread-like member such as steel wire rope or chain etc., is arranged in crane etc.The leading section of suspender 81 engages with holding section 58 set on EJ assembly.Holding section 58 is installed as and can dismantles with respect to EJ toggle supporting 51, but also can be set to a part for EJ toggle supporting 51.
Can dynamic pressure plate 13 there is the insertion space 44 of inserting for suspender 81, the EJ assembly that suspender 81 is sling thus not only comprise be disposed in can dynamic pressure plate 13 outsides parts, can also comprise be disposed in can dynamic pressure plate 13 inside parts.The major part of liftout attachment 50 is contained in EJ assembly, and therefore liftout attachment 50 is good with respect to the operating efficiency of installation exercise that can dynamic pressure plate 13.In addition,, after installation exercise, the length from the part of can dynamic pressure plate 13 rearward giving prominence in liftout attachment 50 is shorter compared with total length short and injection (mo(u)lding) machine 10.
Insert space 44 and be for example formed between a pair of arm 42 of upside, as shown in Figure 4, can be included in the slot space 44a of the side 43a formation of extension 43.The bending of the arm 42 that transmits mold clamping force can be suppressed, and the operating efficiency of liftout attachment 50 with respect to installation exercise that can dynamic pressure plate 13 can be improved.
