Abstract

The utility model discloses a die used for fasteners of automobile interior doors. The die comprises a moving die (1), a fixed die (2) and two die chambers (3) which are arranged between the moving die (1) and the fixed die (2). A runner (4) is further arranged between the moving die (1) and the fixed die (2). The two die chambers (3) are symmetrical mutually. A sprue (5) is arranged on either of the two die chambers (3) and the runner (4) is communicated with the two die chambers (3) respectively by virtue of the two sprues (5). The short edges of the two die chambers (3) are arranged next to each other. The two sprues (5) are respectively arranged at the end parts of the two die chambers (3), and the width of the end parts is not as wide as the width of the middle part of the die chambers (3). The die used for fasteners of automobile interior doors has the advantages of uniform pressure to dies and capability of reducing injection pressure and implementing pressure maintaining.

Description

The mould that is used for the automobile inside door attacker

Technical field

The utility model relates to mould applications, relates to or rather a kind of mould for the automobile inside door attacker.

Background technology

The automobile inside door attacker belongs to auto parts machinery.For the manufacture of automobile inside door attacker's mould comprise dynamic model body, cover half body and be located at the dynamic model body and the cover half body between die cavity.Also be provided with runner between described dynamic model body and cover half body.In order to improve the production efficiency of product, the mould that is used for the automobile inside door attacker of prior art generally all is provided with two die cavitys, two products of injection moulding simultaneously.See also shown in Figure 1ly, the adjacent setting in long limit and this two die cavitys of two die cavitys of the mould that is used for the automobile inside door attacker of prior art are symmetrical.The middle part of the long side wall of the passage that described two die cavitys are wider is respectively equipped with cast gate, and described runner is communicated with described two die cavitys respectively by these two cast gates.There is following defective in the mould of this kind prior art: in the process that manufactures a product, advance glue from the place of die cavity wider passages, can cause the pressure of mould inhomogeneous, injection pressure is large and pressurize is not in place, thereby make product surface that shrink mark be arranged, the dermatoglyph of thimble surface of position is shinny, and because injection pressure is large, also easily produce overlap, thereby reduce the qualification rate of product.

The utility model content

The technical problems to be solved in the utility model is, provide a kind of to die pressure evenly, the mould that is used for the automobile inside door attacker that can reduce injection pressure and pressurize is put in place.

Technical solution of the present utility model is, a kind of mould that is used for the automobile inside door attacker with following structure is provided, comprise dynamic model body, cover half body and be located at the dynamic model body and the cover half body between die cavity; Also be provided with runner between described dynamic model body and cover half body; Described die cavity has two, and these two die cavitys are symmetrical; Be equipped with cast gate on described two die cavitys, described runner is communicated with described two die cavitys respectively by these two cast gates; The adjacent setting of the minor face of described two die cavitys; The width that described cast gate is located at respectively described two die cavitys is than on the width at die cavity middle part narrow end.

After adopting above structure, the mould for the automobile inside door attacker of the present utility model compared with prior art, has the following advantages:

The adjacent setting of minor face due to described two die cavitys of the mould for the automobile inside door attacker of the present utility model; The width that described cast gate is located at respectively described two die cavitys is than on the width at die cavity middle part narrow end.Can not spread when advancing glue due to charging aperture quickly, can accomplish effective pressurize, also can reduce injection pressure, pressure to mould is also even, thereby make the product surface shrink mark not obvious, the dermatoglyph of thimble surface of position is without shinny, and injection pressure is little, also just be not easy to produce overlap, thereby can improve the qualification rate of product.

As a kind of improvement of the present utility model, on the end on the long limit that the width that described two cast gates are located at respectively described two die cavitys is thinner than the die cavity middle part.After adopting this kind structure, the end width of growing the limit due to die cavity is narrow, and the glue that can effectively scatter, and is therefore the optimum position of charging aperture.

Description of drawings

Fig. 2 is the blast structural representation of the mould for the automobile inside door attacker of the present utility model.

Shown in figure: 1, dynamic model body, 2, the cover half body, 3, die cavity, 3.1, minor face, 4, runner, 5, cast gate.

The specific embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

See also shown in Figure 2, the mould for the automobile inside door attacker of the present utility model comprise dynamic model body 1, cover half body 2 and be located at dynamic model body 1 and cover half body 2 between die cavity 3.Also be provided with runner 4 between described dynamic model body 1 and cover half body 2.Described die cavity 3 has two, and these two die cavitys 3 are symmetrical.Be equipped with cast gate 5 on described two die cavitys 3, described runner 4 is communicated with described two die cavitys 3 respectively by these two cast gates 5.The adjacent setting of minor face 3.1 of described two die cavitys 3.The width that described cast gate 5 is located at respectively described two die cavitys 3 is than on the width at die cavity 3 middle parts narrow end.In this specific embodiment, on the end on the long limit that the width that described two cast gates 5 are located at respectively described two die cavitys 3 is thinner than die cavity 3 middle parts.

In this concrete enforcement, described mould for the automobile inside door attacker is used for 08 section of Jetta automobile inside door attacker of injection moulding.

Claims (2)

1. mould that is used for the automobile inside door attacker, comprise dynamic model body (1), cover half body (2) and be located at dynamic model body (1) and cover half body (2) between die cavity (3); Also be provided with runner (4) between described dynamic model body (1) and cover half body (2); Described die cavity (3) has two, and these two die cavitys (3) are symmetrical; Be equipped with cast gate (5) on described two die cavitys (3), described runner (4) is communicated with described two die cavitys (3) respectively by these two cast gates (5); It is characterized in that: the adjacent setting of minor face of described two die cavitys (3); The width that described cast gate (5) is located at respectively described two die cavitys (3) is than on the width at die cavity (3) middle part narrow end.
