Description

Electroplating device for automobile plastic parts

Technical Field

A car is a power-driven, non-track-borne vehicle with four or more wheels. It is mainly used to carry people and goods, and to tow vehicles carrying people and goods. During the production process of the car, its plastic parts need to be electroplated. Compared with metal parts, plastic electroplated products can not only achieve a good metal texture, but also reduce the weight of the product. While effectively improving the appearance and decorativeness of the plastic, it also improves its electrical, thermal and corrosion resistance performance. This inevitably requires the use of electroplating equipment for automotive plastic parts.

However, in the process of electroplating automobile plastic parts, the plastic parts need to be placed in an automobile plastic parts electroplating pool and electroplated with an electroplating liquid. Most of the existing electroplating devices have simple structures. In the process of lifting and lowering automobile plastic parts, the parts are easily dropped due to shaking, which in turn affects the electroplating of the parts. At the same time, during the electroplating process, the inner wall of the parts is prone to uneven electroplating, which affects the subsequent use of the parts. Therefore, certain improvements are needed.

In view of this, the present utility model is proposed.
