Description
Technical field
The present invention relates to a kind of oblique fuses of injection mould from core-pulling mechanism.
Background technique
Currently, oblique fuse is to carry out core pulling using independent oil cylinder, due to the other mechanisms of mold in injection mold
Influence, oil cylinder need it is angularly disposed, and also need to be arranged locking mechanism come prevent it is counter move back, then the space occupied is larger, mechanism
It is more complex, the higher cost of installation and maintenance, and in die sinking, it needs oil cylinder first to work, first makes oblique fuse core pulling, then
Dynamic model just starts to act, therefore open time is longer, and mold production efficiency is lower, and production cost is higher.
Summary of the invention
The present invention provides that a kind of structure is relatively simple, occupied space is smaller in view of the above problems and mold production can be improved
The oblique fuse of the injection mould of efficiency is from core-pulling mechanism.
The present invention solves technical solution used in problem above: providing a kind of oblique fuse of the injection mould having following structure
From core-pulling mechanism, it includes being slidably connected at cover half top shoe, the guide pad being fixed on cover half and the limit being fixed on cover half
Position guide rod, the sliding block are equipped with stepped hole, and the limition orientation bar is slidably connected in stepped hole, limition orientation bar upper end
Be fixed on cover half, and limition orientation bar is to slide block down degree position, be equipped with elastic component between the sliding block and cover half, sliding block with
Elastic component is in compressed state when cover half is bonded, and the sliding block is equipped with inclined hole, and oblique fuse is slidably connected in inclined hole, described oblique
The upper end of fuse is T font structure, and the lower end of the guide pad is equipped with the sliding slot of T font, the axis of inclined hole and the bottom surface of sliding slot
Vertically, and tiltedly the upper end of fuse is slidably connected in sliding slot.
After using the above structure, compared with prior art, the present invention is in die sinking, under the action of the elastic member, by sliding block
Ejection downwards so that the relative position of sliding block and product is constant, and under the action of inclined hole and sliding slot so that tiltedly fuse relative to
Product is extracted out outward, and make oblique fuse to be produced along oblique fuse is corresponding always relative to product under cooperation of the inclined hole with sliding slot
The axis direction of inclined hole is mobile on product, to guarantee the success rate of core pulling, sliding block is limited guiding after moving down a fixed spacing
Bar limit, as dynamic model continues to move to, sliding block and product are disengaged;Additional driving, structure phase are not needed during entire core pulling then
To relatively simply, the space occupied is also relatively fewer, and does not need to open hole on cover half again, and cost is relatively low, and is opened in dynamic model
While realize core pulling, can substantially shorten open time, to improve the production efficiency of mold, reduce production cost.Therefore this hair
Bright have the characteristics that make that structure is relatively simple, occupied space is smaller and mold production efficiency can be improved.
As an improvement, stepped hole on the sliding block is two, corresponding limition orientation bar is two, limition orientation bar with
Stepped hole corresponds, and the elastic component is on the medium position between two stepped holes;Then in this way after setting, when sliding block slides
The case where being less prone to inclination and blocking, the stability of sliding is more preferable, to improve stability in use of the invention.
As a further improvement, the aperture in the hole of the stepped hole upper and lower ends is all larger than the aperture in the hole at middle part, it is described
The lower end of limition orientation bar is equipped with annular protrusion, and the outer diameter of the annular protrusion is greater than the aperture of stepped hole mider hole and is less than etc.
The aperture of stomidium under stepped hole, the upper end of slide block face set that there are two respectively correspond the counterbores of two stepped holes, and countersink region
It is point Chong Die with the stepped hole of respective correspondence, sliding sleeve is equipped in the hole of the stepped hole upper end, and equipped with to sliding sleeve limit in counterbore
The briquetting of position;The frictional force between limition orientation bar and stepped hole can then be greatly reduced after sliding sleeve setting, so that sliding block sliding
Corresponding sensitiveer, core pulling is more efficient.
As further improving, the bottom surface of the counterbore is equipped with threaded hole, is combined with lock-screw in threaded hole, described
Briquetting is equipped with centre bore, and the screw rod of lock-screw screws after passing through centre bore with threaded hole;Then such sliding sleeve position-limit mechanism knot
Structure is simple, and components are less, is easily installed, and preparation cost is relatively low.
As further improving, the upper surface of the sliding block is equipped with blind hole, and the middle part between two stepped holes of blind hole
On position, the elastic component is located in blind hole, and length when elastic component nature is greater than the depth of blind hole, the elastic component
For spring;Then after blind hole setting, so that spring the case where pressured state is to be less prone to bending, prevents spring bullet due to deformation
The case where power becomes smaller and leads to not core pulling generation, at the same prevented also from spring occur compression it is excessive and the case where fail,
And then guarantee the stability of spring works, and extend the service life of spring.
As further improving, the sliding block is wedge structure, and the size of upper end of slide block is less than the size of upper end of slide block;
Then this spline structure after sliding block setting, since cover half is equipped with the accommodation groove to match with shape and sliding block, sliding block and cover half are pasted
Even closer, situations such as being less prone to overlap is closed, to can further improve the yield rate of product, and then reduces the production of product
Cost.
It is improved as further, the side of the sliding block is equipped with indent, and indent is in the upper end opening of sliding block;Then indent
When being bonded sliding block with the accommodation groove on cover half, binding face can be prevented and micro-vacuum occur and sliding block is caused to be inhaled
Firmly the case where, can further improve the sliding response speed of sliding block, to improve demoulding efficiency.
