Fig. 2 is a kind of injection molding mould fixed die side action sliders mechanism of the present invention scheme of installation on mould;
Fig. 3 is that a kind of injection molding mould fixed die side action sliders of the present invention mechanical work principle analyzes schematic diagram.
Detailed description of the invention
Fig. 1-3 is depicted as related description figure of the present invention;
A kind of injection molding mould fixed die side action sliders mechanism, comprise Angle Pin 1, compact heap screw 2, slide body power spring 3, compact heap 4, T-slot 5, slide body 6, Angle Pin guide head 7, wear-resistant block 8, latch segment 9, lock bolt block 10, latch segment screw 11, latch segment spring 12, as shown in Figure 1 and Figure 2.
Described compact heap 4 is installed on mould template by compact heap screw 2 is fastening, and Angle Pin 1 is installed with on mould template, and Angle Pin 1 tail end is provided with Angle Pin guide head 7, and on Angle Pin 1, cover has slide body power spring 3.
Described slide body 6 is slidably installed by T-slot 5 with compact heap 4.
Described latch segment 9, latch segment spring 12 are installed on mould template by latch segment screw 11, and latch segment spring 12 is in compressive state; Lock bolt block 10 is installed on slide body 6 by screw; Wear-resistant block 8 is installed on mould template by screw.
Described wear-resistant block 8 is designed with the inclined-plane for locking sliding block body 6 during closure state, offers the gathering sill matched with Angle Pin 1, Angle Pin guide head 7 in slide body 6 body.
Further, illustrate for ease of operation principle of the present invention, the mould mating parts that Fig. 3 need point out comprises impression bolster 13, die cavity mold insert 14, core mold insert 15, core fixing plate 16; Corresponding, described compact heap 4 is installed on mould template impression bolster 13 by compact heap screw 2 is fastening, and Angle Pin 1 is installed with on mould template impression bolster 13; Described latch segment 9, latch segment spring 12 are installed on mould template core fixing plate 16 by latch segment screw 11, and wear-resistant block 8 is installed on mould template core fixing plate 16 by screw; In Fig. 3, a, b, c, d, e, f are control point, and wherein, a is the spacing terminal of Angle Pin guide head 7 gathering sill in slide body 6 body, and b, c, d are the intermediate control point on Angle Pin 1, and e is the control point on latch segment 9, and f is the control point on lock bolt block 10.
During real work, as shown in Figure 3, its motion operation principle is as follows:
Overall basic functional principle is: after mould die sinking, slide body 6 is first broadside one segment distance on dynamic model, after having loosed core in slider head side, slide body 6 and dynamic model depart from completely, slide body 6 is held by stationary mould for mould template, and dynamic model continues to retreat, and is withdrawn into the space that product can eject, then product ejects from core mold insert by thimble, completes the demoulding of whole product.
1) complete after side small distance core-pulling die die cavity opens, under the pulling of injection machine push rod, mould dynamic model part moves down and is progressively separated with cover half part, now, Angle Pin 1, compact heap screw 2, compact heap 4, impression bolster 13, die cavity mold insert 14 stays on fixed die plate of injection molding machine motionless, the corresponding moving movement of Injection Motor Template followed by other part, the anti-slide body 6 that pushes of slide body power spring 3 springback power does along T-slot 5 movement of gliding, and simultaneously, what 12, latch segment spring withstood slide body 6 by latch segment 9 moves downward trend, latch segment 9 is simultaneously again by catching on lock bolt block 10, when the control point a point on slide body 6 is relative to when on Angle Pin 1, motion control point moves to c point by b point, the preliminary small distance that slide body 6 completes the side of product is loosed core, now, as shown in K figure in Fig. 3, f point on lock bolt block 10 moves to the control point e point on latch segment 9, latch segment 9 catches on effect by losing to lock bolt block 10, slide body 6 will be separated with dynamic model completely, slide body 6 will stay and stationary mould for mould side under T-slot 5 catches on, thus loose core in the side realizing product,
2) loose core completely and abdicate product and eject space under the pulling of injection machine push rod, mould dynamic model part move down to continue with cover half part away from, now, block power spring 3 springback power continues the anti-slide body 6 that pushes and does along T-slot 5 movement of gliding, until the control point a point on slide body 6 is relative to when on Angle Pin 1, motion control point moves to d point by c point, slide body 6 is caught on by Angle Pin guide head 7, motion can not be continued, thus loose core in the side completing whole product, abdicate product next step eject space.
3) when resetting, course of action is just contrary with die sinking process, before mold cavity is closed, injection machine push rod will promote dynamic model partial reset, time closed, latch segment 9 is under the jacking of latch segment spring 12, first contact with slide body 6, now, a point and Angle Pin 1 on slide body 6, on Angle Pin guide head 7, control point relative motion is d point-c point, after on slide body 6, a point crosses c point, on lock bolt block 10, f point will cross e point on latch segment 9, thus, latch segment 9 progressively goes the locking trend of paired block 6, until a point on slide body 6 completely after the b point on Angle Pin 1, fit in wear-resistant block 8 and bottom surface, slide body 6 lower end, lock slide body 6, mould is completely closed, wait for that next injection cycle starts.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit, those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present invention or surmount the scope that appended claims defines.
