Embodiment

The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out Clearly and completely describing, it is clear that described embodiment is only the part of the embodiment of the utility model, rather than all Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making creative work premise Lower all other embodiments obtained, shall fall within the protection scope of the present invention.

One embodiment of the utility model proposes that a kind of band fixes the stent injection mold of metal insert.

With reference to Fig. 1-2, Fig. 1 is the structure diagram of metal insert, and Fig. 2 is the core of metal insert and stent injection mold Cooperation figure.

In order to increase the intensity of plastic, rigidity, hardness or conducting function, it is necessary to be embedded in long and thin metal inserts in plastic 500, it is integrally formed them.As shown in Figs. 1-2, metal insert 500 is placed on the core 300 of stent injection mold, the gold The body for belonging to inserts 500 is bent into some sections as needed, its middle part is in bar-shape, on the side wall of core 300.

With reference to Fig. 3-4, Fig. 3 is partial structural diagram of the stent injection mold in metal insert, and Fig. 4 is at Fig. 3 labels A Partial approach figure.

The main improved structure of stent injection mold that band provided by the utility model fixes metal insert is metal insert 500 corresponding mould structures, therefore, in figure 3, emphasis shows the mould structure of the part.

As shown in figure 3, the mould structure of the part mainly includes front cavity 100, the rear cavity 200 that upper and lower lamination is set, And core 300.Metal insert 500 is placed in the end of the first end of core 300, and wherein portion is located on the side wall of core 300.Type In the cavity that the first end insertion front cavity 100 of core 300 is surrounded with rear cavity 200.As shown in figure 4, front cavity 100 and metal are embedding The opposite position in the middle part of part 500, to first cavity of the recessed formation in the inside of front cavity 100；Core 300 and metal insert 500 The opposite position in middle part, to second cavity of the recessed formation in the inside of core 300.During injection, plastic is in the first cavity and the second cavity Plastic cement locating piece 400 is formed in the cavity surrounded, so as to being relatively fixed at the middle part of metal insert 500 in the first cavity and second In the cavity that cavity surrounds.

Band provided by the utility model fixes the stent injection mold of metal insert 500 by when plastic is molded, Plastic locating piece is formed at the middle part of metal insert 500, which can be relatively fixed the middle part of metal insert 500 In the cavity that first cavity and the second cavity surround, so as to avoid elongated metal insert 500 from producing asking for offset in injection Topic.

Compared with prior art, the utility model can improve the product quality of the plastic with metal insert 500, and structure letter It is single, easy to manufacture, high financial profit.

Further, the top of first cavity is equipped with the first pointed groove of two bottoms；Second cavity Bottom is equipped with the second pointed groove of two bottoms.Specifically, the bottom of both the first groove and described second groove is in V Type.

In the present embodiment, the positioning of the plastic cement locating piece 400 formed in order to prevent in the first cavity and second are formed Effect.At the top of the first cavity, the first groove is set, so that plastic cement locating piece 400 can form two first protrusions 410, can Holding is in the first cavity；Similarly, the second groove is set in the bottom of the second cavity, so that plastic cement locating piece 400 can shape Into two second protrusions 420, and holding is in Second-Type intracavitary.Thus, with reduce plastic cement locating piece 400 because of machine vibration generating unit Divide displacement, improve the locating effect of plastic cement locating piece 400.

Further, the bottom of the first groove and the second groove is to be serrated.

First groove and the second groove are arranged to zigzag, the plastic cement locating piece 400 that thus can be improved and front cavity 100 With the contact area of core 300, the locating effect of plastic cement locating piece 400 is further improved.

The above is only the preferred embodiment of the present invention, and it does not limit the scope of the patent of the present invention, Under every utility model in the utility model is conceived, equivalent structure made based on the specification and figures of the utility model Conversion, or directly/be used in other related technical areas indirectly and be included in the scope of patent protection of the utility model.
