Abstract
The invention discloses an oxhorn-shaped insert which is additionally provided with fibers for preventing a fracture. The oxhorn-shaped insert is applied to a product needing tunnel type plastic feeding in a die. The die comprises a female die and a male die capable of opening and closing; the oxhorn-shaped insert comprises an oxhorn-shaped insert body, an oxhorn-shaped runner, and an oxhorn-shaped pouring gate, wherein the oxhorn-shaped insert body is arranged inside the male die, and is spliced by two single bodies; one part of the oxhorn-shaped runner is arranged at the joint part of the two single bodies; the other part of the oxhorn-shaped runner is arranged at the joint part of the oxhorn-shaped insert body and the male die; a convex structure is formed by the oxhorn-shaped core body at the other part of the oxhorn-shaped runner; the oxhorn-shaped pouring gate is formed in the joint of the tip of the oxhorn-shaped runner and the product. By adopting the oxhorn-shaped insert, the convex structure is formed in the oxhorn-shaped runner on the basis of a conventional oxhorn-shaped insert. The deformation in ejection can be increased by a stub bar gap formed by the convex structure of the oxhorn-shaped insert. Thus, a stub bar can be smoothly ejected, the oxhorn-shaped insert is convenient to process, and the problem of plastic feeding at the appearance of the product is avoided.
Description
[technical field]
The present invention relates to the minor structure that enters in a kind of mould, be specifically related to one and add fine anti-breaking ox horn and enter son.
[background technology]
In plastic mould Shooting Technique, if when the full outward appearance of product requirement of injection moulding, generally can adopt submarine type glue feeding.But, in the plastics of some shaped article, can add the glass fibre of 50% left and right, a little less than these type of plastics that add glass fibre can be highly brittle after cooling, this type of adds after fiberglass plastic product to utilize ox horn to enter sub-moulding, when thimble ejects product, stub bar will break to enter in son at ox horn, thereby cannot adopt submarine ox horn to enter sub-moulding plastics to add glass fiber product at all.
In view of this, be in fact necessary to provide a kind of ox horn to enter son, add to solve plastics that glass fiber product is easily broken in the time ejecting enters the phenomenon in son entering glue.
[summary of the invention]
In order to achieve the above object, the invention provides one and add fine anti-breaking ox horn and enter son, it is applied to needs the product of hiding into glue in mould, and this mould comprises master mold and male model that can folding, and this adds fine anti-breaking ox horn and enters attached bag and draw together:
Ox horn enters son, and it is located in described male model, and this ox horn enters son and is made up of two monomer splicings;
Ox horn runner, its part is located at described two monomer joint portions, and another part of this ox horn runner is located at described ox horn and is entered joint portion sub and described master mold, and described ox horn enters son and be provided with bulge-structure in described another part ox horn runner;
Cow glue powder, it is located at described ox horn runner tip and described product connection.
Preferably, the cross section of described bulge-structure is for falling infundibulate.
Compared to prior art, the present invention adds fine anti-breaking ox horn and enters son, enter on sub basis, in ox horn runner, to have done a bulge-structure at original ox horn, the deflection when stub bar breach that enters sub-bulge-structure moulding by this ox horn can strengthen and eject, thus can smoothly stub bar be ejected; It is easy to process that this enters son, avoided entering at Surface Appearance the problem of glue.
[accompanying drawing explanation]
Fig. 1 illustrates as the present invention adds fine anti-breaking ox horn and enters sub structural representation.
Fig. 2 illustrates as the present invention adds fine anti-breaking ox horn and enters sub side sectional view.
Fig. 3 illustrates as the present invention adds fine anti-breaking ox horn and enters sub stub bar.
[specific embodiment]
Below in conjunction with accompanying drawing, the specific embodiment of the invention is described in detail.
Please refer to shown in Fig. 1 and Fig. 2, the present invention adds fine anti-breaking ox horn and enters son, it is applied to needs the product 10 of hiding into glue in mould, in this product 10, there is the glass fibre of 50% left and right, this mould comprises master mold 100 and male model 200 that can folding, also have thimble 300, this adds fine anti-breaking ox horn and enters attached bag and draw together:
Ox horn enters son 400, and it is located in described male model 200, and this ox horn enters son 400 and is made up of two monomer splicings, and this ox horn enters son 400 and is located at described thimble 300 upper ends;
In the present embodiment, the cross section of described bulge-structure 411 is for falling infundibulate.
When die sinking, male model plate 200 is separated with caster 100, product 10 is now molded, refer to shown in Fig. 3, wherein the stub bar 11 of moulding is corresponding with the shape of described ox horn runner 410, this stub bar 11 remains in ox horn runner 410, by thimble 300 by upwards jack-up of the stub bar in ox horn runner 410 11, because this bulge-structure 411 forms a breach of falling infundibulate on this stub bar 11, described thimble 300 upwards when jack-up the breach of this stub bar 11 strengthened deflection, enter son 400 thereby smoothly stub bar 11 is ejected to ox horn in the situation that not fractureing stub bar 11.
Compared to prior art, the present invention adds fine anti-breaking ox horn and enters son, enter on son 400 basis in ox horn runner 410, to have done a bulge-structure 411 at original ox horn, the deflection when stub bar 11 that enters sub-bulge-structure 411 moulding by this ox horn can strengthen and eject, thus can smoothly stub bar 11 be ejected; The present invention adds fine anti-breaking ox horn and enters son and realized and add glass fiber product with submarine type glue feeding moulding, has avoided entering at Surface Appearance the problem of glue.
Be pointed out that, the invention is not restricted to above-mentioned embodiment, any simple modification, equivalent variations and modification that any those skilled in the art do above-described embodiment based on technical solution of the present invention, all fall within the scope of protection of the present invention.
