High-light injection molding process taking electroplated part as insert

Abstract

The invention relates to a high-light injection molding process taking an electroplated part as an insert. The high-light injection molding process comprises the following steps that producing and machining are carried out to obtain the electroplated part, wherein the electroplated part is provided with a plastic liquid feeding hole and an exhaust hole channel which penetrate back and forth, the near edge position of the electroplated part is provided with "I"-shaped clamping structures at intervals in the circumferential direction, and the two sides of the I-shaped clamping structures form hollowed-out plastic material hole channels; the electroplated part is placed into a mold cavity of a fixing mold of an injection mold; mold closing of the mold is carried out, the exhaust hole channelof the electroplated part corresponds to an exhaust hole of the mold, and the plastic liquid feeding hole of the electroplated part corresponds to a hot runner feeding hole of a moving mold of the mold; and a high-light plastic part is injected and formed, the two sides of the "I"-shaped clamping structures are filled with plastic materials of the high-light plastic part, the plastic materials arecured to form an injection molding finished product assembly, wherein the "I"-shaped clamping structures of the electroplated part are nested inside the high-light plastic part. According to the high-light injection molding process, stable color separation bonding between the electroplated part and the injection molding part can be achieved, the procedures are reduced favorably, the cost is reduced, the appearance quality of a product is guaranteed, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of injection molding of automobile decoration parts, in particular to a high-gloss injection molding process using electroplating parts as inserts. Background technique [0002] With the development of automobile manufacturing technology, more and more OEMs are pursuing the novelty and beauty of the interior and exterior decoration parts of cars. Outstanding shape design, eye-catching appearance style and innovative surface treatment technology have become the key points to attract customers to buy cars. main selling point.

Problems solved by technology

[0003] At present, electroplating colors and plastic colors on the market need to achieve color separation and layered visual effects, mainly through the following two methods: first, after different surface treatments of electroplated parts and plastic parts, the gap between the parts is realized by buckle or welding process. The assembly is fixed to achieve the color separation effect. The disadvantage of this solution is that the assembly process and assembly equipment are increased, the assembly efficiency is low and the cost of manufacturing is increased; the second type adopts a two-color injection molding process, and the electroplated part uses ABS material, and the non-electroplated side Using PC material, the two materials are injected together and electroplated to achieve the color separation effect. The disadvantage of this solution is that during the process, surface problems such as flow marks, pitting, and yellowing are prone to occur on the non-electroplating side, which affects the appearance of the product.
