Specific embodiment
To keep the technical problem to be solved in the present invention, technical solution and advantage clearer, below in conjunction with attached drawing and tool
Body embodiment is described in detail.
As shown in Figures 1 to 6, umbrella shape slanted ejecting mechanism of the present invention, including stepped core pulling fuse 1, the pumping
Core fuse 1 includes linkage section 11, ejection section 12 and core pulling section 13, wherein the linkage section 11 is fixedly connected with preceding mould, the top
Section 12 is in a circular table shape out, is equipped with multiple umbrella shape oblique tops coincideing with core pulling fuse 1 around center axis thereof in 1 outer rim of core pulling fuse
2, button bit groove 21, the button bit groove 21 and product circle card pipe back-off are equipped with close to the side of core pulling section 13 in umbrella shape oblique top 2
Structure matches, and the umbrella shape oblique top 2 surrounds product tubular type chamber, the umbrella close to one end of button bit groove 21 and core pulling section 13
The other end of shape oblique top 2 is abutted against with linkage section 11, reduces the gap between ejection section 12 and umbrella shape oblique top 2, makes to eject section 12
Umbrella shape oblique top 2 is pushed up outward more easily, the core pulling stroke of core pulling fuse 1 is reduced, in umbrella shape oblique top 2 close to one end of linkage section 11
Equipped with tilted footstock 3, one end of the tilted footstock 3 is fixedly connected with preceding mould, and the other end and umbrella shape oblique top 2 of the tilted footstock 3 are detained
It connects.When mould ejection, ejection section 12 pushes up umbrella shape oblique top 2 outward, separates umbrella shape oblique top 2 with the circle card pipe of injecting products, real
Existing product stripping solves the problems, such as that the demoulding of back-off glue position is difficult in the prior art.
As shown in Figures 5 to 7, the umbrella shape oblique top 2 is equipped with convex detent 22, the oblique top close to one end of tilted footstock 3
Seat 3 is equipped with the convex grooves 31 to match with convex detent 22.The convex detent 22 of the umbrella shape oblique top 2 is embedded in tilted footstock 3
Convex grooves 31 on, convenient for fixed umbrella shape oblique top 2, prevent umbrella shape oblique top 2 from shifting, improve the injection molding matter of injecting products
Amount；Meanwhile when ejecting section 12 for the ejection of umbrella shape oblique top 2, the convex grooves 31 provide the enough deviation angles of umbrella shape oblique top 2
Space.
As shown in Figure 2 and Figure 6, the umbrella shape oblique top 2 is equipped with dovetail groove 23, the dovetail away from the side of core pulling fuse 1
Slot 23 plays the role of fixed 2 gradient of umbrella shape oblique top, matches, while playing the role of guiding with template, makes mould ejection machine
Structure movement is more stable, and the dovetail groove 23 is formed by draft.
In the present invention, when the symmetrical bus angulation of the ejection section 12 is excessive, although by umbrella shape oblique top 2 and can produce
Product round card pipe back-off glue position separation, but cannot be guaranteed that core pulling fuse 1 is kept completely separate with injecting products, it may cause in pipe and take out
The phenomenon that core section 13 is interfered, while the overall width of the ejection section 12 is excessive, improves the overall width of mold, indirectly
Improve the cost of mold.No doubt, the symmetrical bus angulation of the ejection section 12 is more than or equal to 2 °, and is less than or equal to 6 °.
In the present embodiment, the symmetrical bus angulation of the ejection section 12 is 4 °, has not only met mould ejection stroke, but also can make mold
Overall width reach most suitable, reduce mould production cost.
As shown in Figure 2 and Figure 4, there are four the umbrella shape oblique tops 2, symmetrical 2 angulation of umbrella shape oblique top is more than or equal to 6 °,
And it is less than or equal to 14 °.In the present embodiment, symmetrical 2 angulation of umbrella shape oblique top is 10 °.
When mold clamping, product is in the intracavitary molding of type, referring to Fig.1；Injection molding be cooled and shaped after product mold be opened into
When row demoulding, referring to Fig. 2, core pulling fuse 1 is moved toward far from injecting products direction, since ejection section 12 is close to 13 one end of core pulling section
Outer diameter be greater than ejection section 12 close to the outer diameter of 11 one end of linkage section, when demoulding, eject section 12 for umbrella shape oblique top 2 and eject one outward
Then fixed distance, the distance for being angularly offset umbrella shape oblique top 2 make the button bit groove 21 in each umbrella shape oblique top 2 and produce
Product circle card pipe back-off glue position demoulding is realized in product circle card pipe separation.
The present invention, occupancy die space is small, at low cost, and structure is simply firm, solves product back-off glue position demoulding hardly possible, demoulding
The problem of ejecting mechanism and mold are interfered.
It is aobvious for those skilled in the art by the disclosure although the present invention is described in detail referring to above example
And be clear to, it, can be to this in the case where not departing from the principle of the present invention and scope that the claim limits
Invention makes a variety of changes or modifies.Therefore, the detailed description of the embodiment of the present disclosure is only used to explain, rather than is used to limit this
Invention, but it is defined by the subject-matter of the claims the range of protection.
