Abstract

The utility model discloses a towing-tie-added breaking-proof ox horn insert core which is applied to products which needs submarine glue-feeding in a die. The die comprises a female die and a male die. The towing-tie-added breaking-proof ox horn insert core comprises an ox horn insert core, an ox horn runner, an ox horn gate, wherein the ox horn insert core is arranged in the male die, and the ox horn insert core is composed of two pieces of single bodies in a split joint mode; one part of the ox horn runner is arranged on a joint part of the two pieces of single bodies, the other part of the ox horn runner is arranged on a joint part of the ox horn insert core and the female die, and a protrusion structure is arranged on the ox horn insert core in the other part of the ox horn runner; and the ox horn gate is arranged at the connecting position of the ox horn runner top end and the products. According to the towing-tie-added breaking-proof ox horn insert core, the protrusion structure is arranged in the ox horn runner on the basis of an original ox horn insert core, a stub bar notch formed by the protrusion structure of the ox horn insert core can increase deflection when the stub bar is ejected, so that the stub bar can be successfully ejected. The insert is easy to machine, and the problem that glue-feeding are required on the outer surfaces of the products is avoided.

Description

Add fine anti-breaking ox horn and enter son
[technical field]
The utility model relates to the minor structure that enters in a kind of mould, is specifically related to a kind ofly add fine anti-breaking ox horn and enter son.
[background technology]
In the plastic mould Shooting Technique, if during the full outward appearance of product requirement of injection moulding, generally can adopt submarine type glue feeding.Yet, can add the glass fibre of 50% left and right in the plastics of some shaped article, a little less than these type of plastics that add glass fibre can be highly brittle after cooling, utilize ox horn to enter sub-moulding after this type of adds the fiberglass plastic product, when thimble ejects product, stub bar will break to enter in son at ox horn, thereby can't adopt the submarine ox horn to enter sub-moulding plastics to add glass fiber product at all.
In view of this, in fact be necessary to provide a kind of ox horn to enter son, to solve plastics, add that glass fiber product is easily broken when ejecting is advancing the phenomenon of glue in entering son.
[summary of the invention]
In order to achieve the above object, the utility model provides a kind of and adds fine anti-breaking ox horn and enter son, and it is applied in mould need the product of hiding into glue, 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 comprised of two monomer splicings;
The ox horn runner, its part is located at described two monomer joint portions, and another part of this ox horn runner is located at the joint portion that described ox horn enters son 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 utility model adds fine anti-breaking ox horn and enters son, enter on sub basis to have done a bulge-structure at original ox horn in the ox horn runner, 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 advancing at Surface Appearance the problem of glue.
[accompanying drawing explanation]
Fig. 1 illustrates as the utility model adds fine anti-breaking ox horn and enters sub structural representation.
Fig. 2 illustrates as the utility model adds fine anti-breaking ox horn and enters sub side sectional view.
Fig. 3 illustrates as the utility model adds fine anti-breaking ox horn and enters sub stub bar.
[specific embodiment]
Below in conjunction with accompanying drawing, the utility model specific embodiment is described in detail.
Please refer to shown in Fig. 1 and Fig. 2, the utility model adds fine anti-breaking ox horn and enters son, it is applied in mould need the product 10 of hiding into glue, the glass fibre that there is 50% left and right in this product 10, 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 comprised of two monomer splicings, and this ox horn enters son 400 and is located at described thimble 300 upper ends;
Ox horn runner 410, its part is located at described two monomer joint portions, another part of this ox horn runner 410 is located at the joint portion that described ox horn enters son 400 and described master mold 100, and described ox horn enters son 400 and be provided with bulge-structure 411 in described another part ox horn runner 410;
Cow glue powder 420, it is located at described ox horn runner 410 tips and described product 10 connections.
In the present embodiment, the cross section of described bulge-structure 411 is for falling infundibulate.
During die sinking, male model plate 200 is separated with caster 100, product 10 now is 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 the jack-up upwards of the stub bar 11 in ox horn runner 410, form a breach of falling the infundibulate on this stub bar 11 due to this bulge-structure 411, when described thimble 300 makes progress jack-up, the breach of this stub bar 11 has strengthened deflection, thereby enters son 400 in the situation that the stub bar 11 that do not fracture ejects stub bar 11 ox horn smoothly.
Compared to prior art, the utility model adds fine anti-breaking ox horn and enters son, at original ox horn, enter on son 400 basis to have done a bulge-structure 411 in ox horn runner 410, 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 utility model adds fine anti-breaking ox horn and enters son and realized adding glass fiber product with the submarine type glue feeding moulding, has avoided advancing at Surface Appearance the problem of glue.
Be pointed out that; the utility model is not limited 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 solutions of the utility model, all fall in protection domain of the present utility model.
