Description
Technical field
The present invention relates to a kind of mechanisms, more particularly, to a kind of cunning spring bushing mechanism in the block.
Background technology
Sliding block is an indispensable component in injection mold, the back-off of many products can not use mold by the way of
Direct depanning, it is necessary to design slide block structure assisted demoulding, usually can be provided with spring eye, bullet close to the side of dynamic model in sliding block
Spring is provided in spring hole, mold sliding block in molding can compress spring, then be tightly attached on dynamic model, wait for that mold molds
When, sliding block slides in and out, and spring, which restores deformation, at this time to eject sliding block before the driving mechanism with sliding block, long-term production process
In, spring is easily damaged during Repeated Compression and is stuck in sliding block and core, causes sliding block that cannot reset completely, continues at this time
Molding can cause mold generation to break risk.If prepare again injecting products, mold again at this time not molding completely in place, it is high
Warm plastics are possible to directly spray outside mold, are likely to cause an accident to worker.
Invention content
In view of the above-mentioned problems, the present invention provides a kind of cunning spring bushing mechanism in the block, can effectively protect spring exists
The phenomenon that collision bending is generated in the course of work avoids causing sliding block that cannot reset completely and mold because of the failure of spring
Break risk.
The technical scheme is that a kind of cunning spring bushing mechanism in the block, including sliding block, dynamic model, support block, product top
Needle, thimble panel, Ejector Retainer Plate and dynamic mould fixing plate, the product surface side of the dynamic model is provided with outward to be slided for sliding block
Slider layering is vertically provided with inclined guide pillar on the sliding block, and the inclined guide pillar is connected to after passing through sliding block upper and lower surface at cover half,
Inclined guide pillar is inclined outwardly from slider top to bottom direction, and inclined guide pillar follows cover half to synchronize and moves upwards drive cunning when mold molds
Block slides in and out along slider layering, and the side that the sliding block is contacted with dynamic model is provided with spring eye along sliding block glide direction, institute
It states and bushing is set in spring eye, be provided with spring in the bushing, the spring bottom end is contacted with spring eye bottom, the spring
Top contacts outside with sleeve, and the bushing can be slided along spring eye length direction.
Preferably, oblique be upward through after sliding block at the top of it of the inclined guide pillar is connected with inclined guide pillar fixed block, inclined guide pillar
Fixed block is located at sliding block upper surface, and inclined guide pillar is fixed on by inclined guide pillar fixed block on cover half.
Preferably, it is provided with the inclined guide pillar avoiding hollow groove placed for inclined guide pillar at the dynamic model below the sliding block, inclined guide pillar is kept away
Empty slot penetrates through the side wall of dynamic model.
Can effectively protect spring of the present invention is in the state of support slipper after sliding block leaves dynamic model, prevents spring works mistake
The phenomenon that collision bending is generated in journey, is effectively ensured the service life of spring, avoids causing sliding block to fall because of the failure of spring
It falls and occurs the phenomenon that the product surface of mold breaks mould product surface.

Specific implementation mode
Below in conjunction with the accompanying drawings, invention is further described in detail.
As shown in Figures 1 to 9, the present invention provides a kind of cunning spring bushing mechanism in the block, including sliding block 1, dynamic model 2,
The product surface side of support block 3, product thimble 4, thimble panel 5, Ejector Retainer Plate 6 and dynamic mould fixing plate 7, the dynamic model 2 is outside
It is provided with the slider layering 8 slided for sliding block 1, inclined guide pillar 9 is vertically provided on the sliding block 1, the inclined guide pillar 9 is oblique upwards
Inclined guide pillar fixed block 13 is connected at the top of it after sliding block 1, inclined guide pillar fixed block 13 is located at 1 upper surface of sliding block, inclined guide pillar 9
Be connected at cover half by inclined guide pillar fixed block 13, be provided at the dynamic model 2 of the lower section of the sliding block 1 placed for inclined guide pillar 9 it is oblique
Guide post avoiding hollow groove 14, inclined guide pillar avoiding hollow groove 14 penetrate through the side wall of dynamic model 2, and inclined guide pillar 9 leans outward from 1 top of sliding block to bottom direction
Tiltedly, mold mold when inclined guide pillar 9 follow cover half synchronize move upwards band movable slider 1 slid in and out along slider layering 8, the cunning
The side that block 1 is contacted with dynamic model 2 is provided with spring eye 10 along 1 glide direction of sliding block, and bushing 11, institute is arranged in the spring eye 10
It states and is provided with spring 12 in bushing 11,12 bottom end of the spring is contacted with 10 bottom of spring eye, 12 top of the spring and bushing
11 bottoms contact outside, the bushing 11 can be slided along 10 length direction of spring eye.
In the course of work, as shown in Figure 1, after fixed half and moving half 2 molds, injection moulding process is carried out, sliding block 1 is held out against dynamic at this time
2 side of mould, injection moulding process mold after the completion, and cover half exits outward, while cover half drives inclined guide pillar fixed block 13 to synchronize to outward transport
Dynamic, inclined guide pillar fixed block 13 drives inclined guide pillar 9 to move synchronously, and since inclined guide pillar 9 passes through in sliding block 1, sliding block 1 can be along cunning
Block press strip 8 moves, and realizes that sliding block 1 exits the process of dynamic model 2, and spring 12 is still in confined state at this time, and spring 12 extends
Bushing 11 is driven to be moved out along spring eye 10, bushing 11 is supported in 2 side of dynamic model with support slipper 1, and anti-limited slip block 1 is fallen
On dynamic model 2, then thimble panel 5 and Ejector Retainer Plate 6 eject product thimble 4 under the action of oil cylinder upwards, product thimble 4
The product ejection that injection molding is finished, after taking out product, fixed half and moving half 2 molds, and inclined guide pillar fixed block 13 follows cover half to move, band
Dynamic inclined guide pillar 9 moves synchronously, and then is resetted with 1 slid inward of movable slider, and spring 12 is further compressed at this time, and bushing 11 is retracted
In spring eye 10, in the process, spring 12 is only contacted with bushing 11 and 10 bottom surface of spring eye, is not in the possibility of bending,
The service life of spring can be effectively ensured, whole process effective protection spring 12 so that the safety in use of spring 12
Reliably, to ensure that sliding block 1 will not be fallen because spring 12 fails on dynamic model 2.
The above, be only the present invention better embodiment, not to invention make any form of restriction, it is every according to
According to the technical principle of the present invention any simple modification, equivalent variations or modification made to the above embodiment, the present invention is still fallen within
In the range of technical solution.
