Description
Technical field
The present invention relates to a kind of oblique fuse of injection mould from core-pulling mechanism.
Background technology
At present, in injection mold, oblique fuse is to carry out core pulling using independent oil cylinder, due to the other mechanisms of mould
Influence, oil cylinder need it is angularly disposed, and also need to set locking mechanism come prevent it is counter move back, then the space taken is larger, mechanism
More complicated, installation and the cost safeguarded are higher, and first cause oblique fuse core pulling, then, it is necessary to oil cylinder first works in die sinking
Dynamic model just starts to act, therefore open time is longer, and mould production efficiency is relatively low, and production cost is higher.
The content of the invention
The present invention is for a kind of structure of problem above offer is relatively simple, space-consuming is smaller and can improve mould production
The oblique fuse of injection mould of efficiency is from core-pulling mechanism.
The present invention solve problem above used in technical scheme be：A kind of oblique fuse of injection mould with following structure is provided
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 provided 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 provided 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 provided with inclined hole, and oblique fuse is slidably connected in inclined hole, described oblique
The upper end of fuse is T font structures, and the lower end of the guide pad is provided with the chute of T fonts, the axis of inclined hole and the bottom surface of chute
Vertically, and tiltedly the upper end of fuse is slidably connected in chute.
After above structure, compared with prior art, the present invention is in die sinking, in the presence of elastic component, by sliding block
Ejection downwards so that the relative position of sliding block and product is constant, and in the presence of inclined hole and chute so that oblique fuse relative to
Product is outwards extracted out, and make it that oblique fuse is produced along oblique fuse is corresponding all the time relative to product under cooperation of the inclined hole with chute
The axis direction movement of inclined hole on product, so as to ensure that the success rate of core pulling, sliding block are limited guiding after moving down a determining deviation
Bar is spacing, and as dynamic model continues to move to, sliding block disengages with product；Additional driving, structure phase are not needed during whole core pulling then
To relatively simple, the space of occupancy is also relatively fewer, and need not the opened hole on cover half again, cost is relatively low, and is molded in dynamic model
While realize core pulling, can significantly shorten open time, so as to improve the production efficiency of mould, reduce production cost.Therefore this hair
It is bright have make the characteristics of structure is relatively simple, space-consuming is smaller and can improve mould production efficiency.
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；After then so setting, when sliding block slides
The situation for tilting and blocking is less prone to, the stability of slip is more preferable, so as to improve the stability in use of the present invention.
As a further improvement, the aperture in the hole of the stepped hole upper and lower ends is all higher than the aperture in the hole at middle part, it is described
The lower end of limition orientation bar is provided with annular protrusion, the external diameter of the annular protrusion be more than the aperture of stepped hole mider hole and less than etc.
The aperture of stomidium under stepped hole, the upper end of slide block face are provided with two counterbores for corresponding to two stepped holes respectively, and countersink region
It is point overlapping with the stepped hole of respective correspondence, sliding sleeve is provided with the hole of the stepped hole upper end, and provided with to sliding sleeve limit in counterbore
The briquetting of position；Then the frictional force between limition orientation bar and stepped hole can be greatly reduced in sliding sleeve after setting so that what sliding block slided
Corresponding sensitiveer, core pulling is more efficient.
As further improving, the bottom surface of the counterbore is provided with screwed hole, and lock-screw is combined with screwed hole, described
Briquetting is provided with centre bore, and the screw rod of lock-screw screws after passing through centre bore with screwed hole；Then such sliding sleeve position-limit mechanism knot
Structure is simple, and parts are less, is easily installed, and it is relatively low to prepare cost.
As further improving, the upper surface of the sliding block is provided 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 during elastic component nature is more than the depth of blind hole, the elastic component
For spring；After then blind hole is set so that spring is the situation for being less prone to bending in pressured state, prevent spring because of deformation bullet
The situation that power diminishes and leads to not core pulling occurs, while situation that is excessive prevented also from spring appearance compression and failing occurs,
And then ensure 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, because cover half is provided with the storage tank to match with shape and sliding block, sliding block pastes with cover half
Even closer, situations such as being less prone to overlap is closed, so as to can further improve the yield rate of product, and then reduces the production of product
Cost.
Improved as further, the side of the sliding block is provided with indent, and indent is in the upper end open of sliding block；Then indent
When make it that sliding block is bonded with the storage tank on cover half after setting, binding face can be prevented and micro-vacuum occur and cause sliding block to be inhaled
Situation firmly, the slip response speed of sliding block is can further improve, so as to improve demoulding efficiency.
