Description

Interior automotive exterior bright wisp of moulding plastics of mould

Technical Field

The utility model relates to an automotive exterior bright wisp of moulding plastics in mould for automotive exterior bright wisp field.

Background

At present, the automobile exterior bright wisp mainly comprises two materials, namely an aluminum material and a stainless steel material, and the two materials have use limitations.

The disadvantages of the stainless steel automobile exterior bright strip are as follows:

1. the weight is higher, and the weight of the stainless steel bright strip is higher than that of the aluminum bright strip;

2. the high bright black appearance is realized by two process modes of film covering and powder spraying, and both the two processes have higher cost; the powder spraying stainless steel has high process difficulty of high brightness and black, high surface quality control difficulty and poor environmental evaluation;

3. for exterior bright strip products with high curvature and complex shapes, the process has process limitation;

4. after the rolled stainless steel product is subjected to stretch bending, the surface atomization is inconsistent with the surface appearance of other positions of the product, and the size and quality of the stretch bending position are difficult to control;

5. if the bending and complex modeling of the die cutting process experiment are selected, the cost is very high.

The aluminum automobile exterior bright strip has the following disadvantages:

1. high cost

2. Complicated process, anodic oxidation process and poor environmental evaluation

3. The highlight black is mainly finished by spraying paint, and the process investment cost is higher

4. The process limitation also exists for the product with high bending degree and complex modeling

The automobile window frame bright strip has a large number of high bright black appearances, the exterior bright strip is widely applied to high-grade automobile models, on the other hand, the automobile bright strip is more personalized in shape, the greater the product curvature, the higher the process difficulty, and the great challenge is brought to production and quality guarantee for the traditional bright strip production process of rolling and stretch bending.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming the not enough of prior art, provide an automobile exterior trim bright wisp of moulding plastics in mould, can replace current metal exterior trim bright wisp.

One technical scheme for achieving the above purpose is as follows: an in-mold injection molding automobile exterior trim bright strip comprises an injection molding part and an engineering plastic layer;

the both sides of injection molding are for interior joint structure that is used for being connected with vehicle outside conducting bar and panel beating of detaining, the outside of injection molding is connected with the one deck engineering plastic layer, this engineering plastic layer is not right the joint structure causes the interference, the surface spraying of engineering plastic layer has one deck metallic material thin layer.

Further, the engineering plastic layer is made of PP.

Further, the engineering plastic layer is made of ABS.

Still further, the thickness of engineering plastic layer is 0.5 mm.

The utility model discloses an automobile exterior trim bright wisp of moulding plastics in mould has following advantage:

1. the injection molding process is adopted for the molding of the connecting structure and the basic component, and the adaptability to the bending angle, the molding surface width and the like is strong;

2. the appearance of the bright strip is diversified by adopting an in-mold injection molding process, the color is determined according to a metal material layer sprayed on the surface of the engineering plastic layer, the bright strip has diversity, the appearance of the current product has high brightness black, high brightness (the same as the appearance of a stainless steel bright strip) and matte silver (the same as the appearance of an anodic aluminum oxide bright strip), the product can be researched and developed according to other color requirements, and various patterns can be added to the appearance;

3. the external decorative bright strip book can be matched with a plurality of parts of the side face of the car body and can be applied to parts of a guide groove, an external water cutting part, a corner window and a triangular plate, so that the appearance consistency of the whole circle of bright strips on the side face is ensured;

4. the outer decorative bright strip of the product has light weight, and compared with the common stainless steel bright strip, the weight is lighter by more than 50%, and the whole vehicle can be lightened.

Detailed Description

In order to better understand the technical solution of the present invention, the following detailed description is made by specific embodiments:

please refer to fig. 1. The utility model discloses an automobile exterior trim bright wisp of moulding plastics in mould, including injection molding 2 and engineering plastic layer 1. The both sides of injection molding 2 are the joint structure 21 that is used for being connected with vehicle outside conducting bar and panel beating of interior knot, and the outside of injection molding 2 is connected with one deck engineering plastic layer 1, and this engineering plastic layer 1 does not cause the interference to the joint structure, and the surface spraying of engineering plastic layer 1 has one deck metallic material thin layer.

The engineering plastic layer 1 can be made of PP or ABS, or other materials which are beneficial to spraying metal film materials on the engineering plastic layer. The thickness of the engineering plastic layer 1 is 0.5 mm.

The injection molding 2 is as the basis of supporting engineering plastic layer 1, and is fixed with vehicle guide slot and panel beating joint, plays itself to have certain structural strength, and engineering plastic layer 1 that sets up on it then is as the basement of spraying metal material thin layer. Because the processing technology of injection molding is adopted, the utility model discloses the molding can carry out adjustment by a wide margin as required.
