Specific embodiment
It is described in detail below in conjunction with embodiment of the attached drawing to technical solutions of the utility model.Following embodiment is only
For clearly illustrating the technical solution of the utility model, therefore it is only used as example, and it is originally practical to cannot be used as a limitation limitation
Novel protection scope.
As shown in Figures 1 to 7, cylinder slide block core pulling mutual interlocking gear 20 provided in this embodiment, setting by mold core 11, after
In the rear mold 10 of the components such as template 12, vertical plate 13 and bottom plate 14 composition, the specific structure of rear mold 10 can refer to traditional dies, herein
It is not repeating.In the present embodiment, cylinder slide block core pulling mutual interlocking gear 20 includes: briquetting 21, oil cylinder 22, slide 23 and sliding block 24.
As shown in figures 1 and 3, briquetting 21 is arranged in rear mold 10, specifically may be provided at the outside portion of vertical plate 13, briquetting 21
On offer guide groove 211, and the generatrix direction of guide groove 211 is vertical with the molding direction of mold, (as long as two in actual use
Person is not parallel just, but vertical guide effect is most obvious, and movement executes rapider).Guide groove 211 on oil cylinder 22 and briquetting 21
Bus it is parallel be installed in rear mold 10, slide 23 is installed in the guide groove 211 of briquetting 21, and can be along guide groove 211
Bus sliding；22 piston rod of oil cylinder is connected by a connecting rod 25 and slide 23, with flexible driving slide 23 in guide groove 211
Interior sliding.
Referring to fig. 2, the other end of slide 23 has inclined-plane 231, the inclined direction on inclined-plane 231 and the glide direction of slide 23
Angle be preferably arranged within the scope of 30 ° -45 °, to guarantee that slide 23 passes through the wedging effect that generates of inclined-plane 231；It is opened on inclined-plane 231
If the T-slot 232 that the inclined direction along inclined-plane 231 is arranged, the T-type connector 242 that sliding block 24 is arranged by one end is slidably
Inserting to the T-slot 232 of slide 23 on.
Referring to 4, sliding block 24 can be plugged in axial sliding in rear mold 10 along it, and the outer end of sliding block 24 is connect with mold core 11,
To push mold core 11 to carry out injection molding die mould；The end face of the butt of sliding block 24 in parallel with the inclined-plane 231 of slide 23 skewed,
And the two sides of the close butt in sliding block 24 offer the groove 241 parallel with inclined-plane 231, form the butt of sliding block 24 aforementioned
The T-type connector 242 being adapted to T-slot 232, and then matching by the T-slot 232 that is obliquely installed and T-type connector 242
It closes, when slide 23 is mobile, sliding block 24 can be pushed along its axial stretching by the wedge on inclined-plane；And referring to Fig. 5, groove
The first side wall of 241 24 front end of close sliding block has the planar section 2411 vertical with 24 axis of sliding block, and planar section 2411 is set
Set one end in 24 front end of close sliding block of 241 side wall of groove, the other parts of setting 2411 this one side wall of planar section be still in
The parallel bevel phase 2412 in inclined-plane 231, to cooperate with T-slot 232.In the present embodiment, the axis of sliding block 24 preferably relative to
What the direction of motion of rear mold 10 was obliquely installed, so that the outer end for the sliding block 24 that butt is arranged close to 13 outside portion of vertical plate can be with good
Good posture is connect with mold core 11.
Cylinder slide block core pulling mutual interlocking gear 20 using the above structure, when molding, the stretching of oil cylinder 22 slides into slide 23
One end of the separate oil cylinder 22 of guide groove 211, by the cooperation of T-slot 232 and T-type connector 242, slide 23 passes through its inclined-plane
231, the bevel phase 2412 on the first side wall of 24 front end of close sliding block of groove 241 applies inclined wedging force, sliding block 24
It can only be stretched out to 11 side of mold core under the constraint of rear mold 10, mold core 11 is pushed to enter injection molding station.Later, in molding state
Under be molded, sliding block 24 will receive the injection pressure transmitted by mold core 11, at this point, referring to Fig. 5, sliding block 24 is to slide 23 1
The inclined-plane 231 of side stress, bevel phase 2412 and slide 23 on the first side wall of 24 front end of close sliding block of groove 241 agrees with,
And the planar section 2411 on the first side wall then can be in seating to the plane towards 24 side of sliding block of slide 23, and then passes through two
The vertical stress of plane prevents sliding block 24 from retracting, thus effectively prevent sliding block 24 because injection pressure is excessive and the case where retreat
Occur.
When being opened after the completion of injection molding, the retraction of oil cylinder 22 keeps slide 23 sliding to one end of the close oil cylinder 22 of guide groove 211
Dynamic, during this, referring to Fig. 6, the plane towards 24 side of sliding block of slide 23 progressively disengages flat on 241 the first side wall of groove
Face section 2411, until T-slot 232 and T-type connector 242 are in complete inclined-plane mated condition.Later, oil cylinder 22 continues to drive
Sliding block 23 retracts, and referring to Fig. 7, T-slot 232 passes through it close to the cell wall 2321 of open face, to the close sliding block 24 of groove 241
Second side wall surface 2413 of the side of butt applies inclined lower pressure, retracts sliding block 24 to pull down T-type connector 242,
Sliding block 24 is set to reach the retraction station after die sinking.
To protect the reciprocating motion of above-mentioned cylinder slide block core pulling mutual interlocking gear 20 reliably, while realizing automatic
Control, the present embodiment are also provided with travel switch 26 for it.Referring to Fig. 1, the glide direction along slide 23 is offered on briquetting 21
The strip-shaped hole 212 of arrangement is provided with induction on slide 23 and touches block 233, and to touch block 233 convex across strip-shaped hole 212 for the induction
For the surface of briquetting 21, and travel switch 26 is respectively arranged one at the both ends of strip-shaped hole 212, and then the flexible driving of oil cylinder 22 is slided
Seat 23 is run to after the position of setting, can touch travel switch 26 in the reciprocal transfer point of stroke, and then stop oil cylinder 22
Operation, or the retracted position of change oil cylinder 22 make the commutation operation of slide 23.
In conclusion cylinder slide block core pulling mutual interlocking gear 20 by adopting the above technical scheme, can effectively prevent sliding block 24 because
The case where retreating for injection pressure is excessive, avoids forming more glue or burr on moulding, guarantees the injection molding of product
Quality, makes that mold operation is more stable, safety, is effectively reduced the damage risk in mold operational process, reduce mold repair at
This.
