Afterbody fluting 101 ' be plastic injection-moulded, and promptly the afterbody fluting is arranged on injection molding body, in assembling and project installation process since afterbody plastics intensity a little less than, when using screw-driver to install, occur plastics easily and ftracture or turn round colored phenomenon.

To the problems referred to above in the correlation technique, effective solution is not proposed as yet at present.

The model utility content

In correlation technique, the afterbody of injection moulding screw fluting is prone to cracking or turns round problem such as colored phenomenon, and the utility model provides a kind of injection moulding screw and injection mould, to address the above problem at least.

An aspect according to the utility model provides a kind of injection moulding screw, comprising: screw body, be injected with injection molding body at said screw body afterbody, and also comprise: afterbody is slotted, and is arranged at the tail end of said screw body.

Said tail end is concordant with the tail end of said injection molding body.

Said tail end is protruded the tail end of said injection molding body.

Said tail end depression is arranged at the tail end of said injection molding body.

Said afterbody fluting is I-shaped.

Said afterbody fluting is the cross formula.

Said screw body comprises: the screw section and the metallic stud that connect successively, said tail end is arranged at the afterbody of said metallic stud.

According to the utility model on the other hand, a kind of injection mould is provided, has comprised: above-described injection moulding screw.

Pass through the utility model; Employing is arranged on the afterbody fluting of injection moulding screw the technological means of the tail end of screw body; Solved in the correlation technique; The afterbody of injection moulding screw fluting is prone to cracking or turns round problem such as colored phenomenon, and then has reached the effect that strengthens injection moulding screw afterbody fluting intensity, has improved reliability of products.

Description of drawings

Accompanying drawing described herein is used to provide the further understanding to the utility model, constitutes the application's a part, and illustrative examples of the utility model and explanation thereof are used to explain the utility model, do not constitute the improper qualification to the utility model.In the accompanying drawings:

Fig. 1 is the conventional plastic injection moulding metallic screw structural representation according to correlation technique;

Fig. 2 is injection moulding screw first structural representation according to the utility model embodiment;

Fig. 3 is another structural representation based on injection moulding screw embodiment illustrated in fig. 2;

Fig. 4 is injection moulding screw second structural representation according to the utility model embodiment;

Fig. 5 is another structural representation based on injection moulding screw embodiment illustrated in fig. 4.

Embodiment

Hereinafter will and combine embodiment to specify the utility model with reference to accompanying drawing.Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the application can make up each other.

Embodiment 1

Fig. 2 is injection moulding screw first structural representation according to the utility model embodiment.As shown in Figure 2, this injection moulding screw comprises: screw body 10, be injected with injection molding body 12 at said screw body 10 afterbodys, and the afterbody of this injection moulding screw slots 101, is arranged at the tail end 103 of said screw body 10.

Through the said structure characteristic; Because the position of afterbody fluting has been arranged on (tail end of screw body) on the screw body; With respect in the correlation technique afterbody fluting being arranged on the injection molding body, having strengthened the intensity of the afterbody fluting of injection moulding screw, thereby improved reliability of products.

Above-mentioned tail end 103 can be set to concordant (like Fig. 2 or shown in Figure 4) with the tail end 121 of injection molding body 12; Also can be set to the tail end 121 of the said injection molding body 12 of tail end 103 protrusions; Also can be set to the tail end 121 that tail end 103 depression is arranged at said injection molding body 12, get final product so long as the afterbody fluting is arranged on the tail end 103 of screw body.

The shape of above-mentioned afterbody fluting 101 can be designed to multiple shape according to actual conditions, for example can be set to I-shaped (like Fig. 4 and shown in Figure 5), can also be cross formula (as shown in Figures 2 and 3).

When concrete the application, like Fig. 2 and shown in Figure 4, above-mentioned screw body 10 comprises: the screw section 105 and the metallic stud 107 that connect successively, said tail end 103 is arranged at the afterbody of said metallic stud 107.

Because above-mentioned injection moulding screw does not generally use separately when practical application, for example can be applied in the injection mould, therefore, present embodiment also provides a kind of injection mould, comprising: above-described injection moulding screw.

Embodiment 2

Present embodiment provides a kind of injection moulding screw, and this injection moulding metallic screw can use in the employed D connector of communications equipment.

The purpose of present embodiment is, under the situation that does not change the original purposes of this screw, changes metallic stud injection moulding position and slotting position, overcomes that original injection moulding screw afterbody intensity is low excessively to cause reliability problems in the project installation process.

For achieving the above object, the technological scheme that present embodiment adopted is following:

Like Fig. 2 and shown in Figure 4, the injection moulding screw of present embodiment comprises: by the left-to-right screw section that sets gradually 105, metallic stud 107, plastic injection-moulded body 12, afterbody fluting 101, afterbody is slotted 101 positions on metallic stud 107.In the present embodiment, afterbody fluting 101 can also can be slotted for I-shaped (referring to Fig. 4 and Fig. 5) for cross formula afterbody fluting (referring to Fig. 2 and Fig. 3).
