Inverted-T-shaped structure of car external decoration part

Abstract

The invention belongs to the technical field of car external decoration parts and provides an inverted-T-shaped structure of a car external decoration part. The inverted-T-shaped structure comprises abody and an inverted-T-shaped body arranged on the body, the lower end of the inverted-T-shaped body is the root of the inverted-T-shaped body, and grooves for flow buffering are formed in the peripheral edge of the root of the inverted-T-shaped body. The inverted-T-shaped structure of the car external decoration part has the advantages that through the inverted-T-shaped structure, the defects ofgas marks and the like on the periphery of the inverted-T-shaped body can be well overcome, the inverted-T-shaped body height can be designed to be 3-5 mm, the stereoscopic impression of the appearance modeling is improved, and the inverted-T-shaped structure is more beautiful, high in structural practicability, simple in structure, easy to manufacture and low in cost.

Description

technical field [0001] The invention belongs to the technical field of automobile exterior decorations, and in particular relates to a convex character modeling structure of automobile exterior decorations. Background technique [0002] In the modeling of automobile exterior decoration, the mode of directly designing embossed characters on the decorative strip is often used. The existing technology has defects for this kind of embossed character structure exceeding 1mm. The specific causes of the surface defects of the embossed character structure: 1. Wall thickness Unevenness causes turbulent flow, and there are air marks on the font. If the sequence valve is filled too quickly, there will be problems such as air lock, and the font part is poorly trapped. Therefore, if it is filled slowly, the production efficiency will be greatly reduced and the cost will increase; 2. Trapped air usually appears around the corners of fonts, which is manifested as circular weld lines. The w...

[0002] In the modeling of automobile exterior decoration, the mode of directly designing embossed characters on the decorative strip is often used. The existing technology has defects for this kind of embossed character structure exceeding 1mm. The specific causes of the surface defects of the embossed character structure: 1. Wall thickness Unevenness causes turbulent flow, and there are air marks on the font. If the sequence valve is filled too quickly, there will be problems such as air lock, and the font part is poorly trapped. Therefore, if it is filled slowly, the production efficiency will be greatly reduced and the cost will increase; 2. Trapped air usually appears around the corners of fonts, which is manifested as circular weld lines. The weld lines caused by these trapped air will lead to appearance defects such as paint bite or poor electroplating. The defects caused by the above cause the existing technology to only Can make fonts with a depth of less than 0.8mm. For convex or concave characters above 1mm, there are still related defects in the production process

However, in the process of product modeling, the font height or depth required by customers often exceeds 1mm. Due to related technical bottlenecks, it cannot fully meet customer requirements. We can only ask customers to change the shape and reduce the font depth or height.
