Description
Technical field
The present invention relates to a kind of mechanism, more particularly, to the sliding spring bushing mechanism in the block of one kind.
Background technology
Sliding block is an indispensable component in injection mold, and the back-off of many products can not be by the way of die sinking
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 with spring hole, mould sliding block in molding can be compressed spring, then be close on dynamic model, treat that mould molds
When, sliding block slides in and out, and spring, which recovers 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 to reset completely, continues at this time
Molding can cause mould generation to break risk.If prepare again injecting products, mould again at this time not molding completely in place, it is high
Warm plastics are possible to directly spray outside mould, and generation accident is likely to worker.
The content of the invention
In view of the above-mentioned problems, the present invention provides the sliding spring bushing mechanism in the block of one kind, its can effectively protect spring exists
The phenomenon of collision bending is produced in the course of work, avoids causing sliding block to reset completely and mould because of the failure of spring
Break risk.
The technical scheme is that a kind of sliding spring bushing mechanism in the block, including sliding block, dynamic model, support block, product top
Pin, thimble panel, Ejector Retainer Plate and dynamic mould fixing plate, the product surface one of the dynamic model is lateral to be provided outside what is slided for sliding block
Slider layering, inclined guide pillar is vertically provided with the sliding block, and the inclined guide pillar is connected at cover half after passing through sliding block upper and lower surface,
Inclined guide pillar is outward-dipping from slider top to bottom direction, and inclined guide pillar follows the synchronous movement upwards of cover half to drive and slides when mould 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
State 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 cover half by inclined guide pillar fixed block.
Preferably, the inclined guide pillar avoiding hollow groove placed for inclined guide pillar is provided with 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 of collision bending is produced in journey, the service life of spring is effectively ensured, avoids causing sliding block to fall because of the failure of spring
The phenomenon for falling to break mould product surface in the product surface of mould occurs.

Embodiment
Below in conjunction with the accompanying drawings, the present invention is described in further detail.
As shown in Figures 1 to 9, the present invention provides the sliding spring bushing mechanism in the block of one kind, including sliding block 1, dynamic model 2,
Support block 3, product thimble 4, thimble panel 5, Ejector Retainer Plate 6 and dynamic mould fixing plate 7, the product surface side of the dynamic model 2 are outside
The slider layering 8 slided for sliding block 1 is provided with, inclined guide pillar 9 is vertically provided with the sliding block 1, the inclined guide pillar 9 is oblique upwards
Inclined guide pillar fixed block 13 is connected with after through sliding block 1 at the top of it, inclined guide pillar fixed block 13 is located at 1 upper surface of sliding block, inclined guide pillar 9
It is connected at cover half by inclined guide pillar fixed block 13, is provided with the dynamic model 2 of the lower section of sliding block 1 for the oblique of the placement of inclined guide pillar 9
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 the top of sliding block 1 to bottom direction
Tiltedly, inclined guide pillar 9 follows the synchronous band movable slider 1 of movement upwards of cover half to be slid in and out along slider layering 8 when mould molds, the cunning
Block 1 is provided with spring eye 10 with the side that dynamic model 2 contacts along 1 glide direction of sliding block, and bushing 11, institute are set in the spring eye 10
State and spring 12 is provided with bushing 11,12 bottom of spring is contacted with 10 bottom of spring eye, 12 top of 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, molds after the completion of injection moulding process, and cover half outwards exits, while cover half drives inclined guide pillar fixed block 13 synchronous to outward transport
Dynamic, inclined guide pillar fixed block 13 drives inclined guide pillar 9 to be synchronized with the movement, and since inclined guide pillar 9 is passed 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 to be dropped in 2 side of dynamic model with support slipper 1, anti-limited slip block 1
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 finished will be molded, 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 is synchronized with the movement, 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 effectively protects spring 12 so that spring 12 is safe in use
Reliably, so as to ensure that sliding block 1 will not fail because of spring 12 and drop on dynamic model 2.
The above, is only the better embodiment of the present invention, not makees limitation in any form to invention, it is every according to
According to the technical principle of the present invention to any simple modification, equivalent variations or modification made for any of the above embodiments, the present invention is still fallen within
In the range of technical solution.
