汽车内饰扶手条INS成型模具设计

Design of INS Forming Mold for Automobile Handrail Trim

对INS工艺过程进行了阐述，并结合轿车前门内饰左右扶手条的INS生产实际，设计了该产品INS工艺所需的膜片镶件。采用膜片高压成型模具．膜片弹顶式冲裁模具以及两板热流遒多浇口注塑模具来实现INS塑件的注望成型生产。所设计的INS工艺成组模具结构简单．设计巧妙新颖。能实现扶手条产品（INS工艺成型）的高良品牢生产，可为同类塑件的生产提供借鉴。

This paper expounds the INS （film insert molding） process, and combines the INS production practice of the left and right handrail trim of the front door of the car, and designs the diaphragm inserts for the INS process of the product. Diaphragm high-pressure molding die, diaphragm top blanking die and two plate hot runner multi gate injection mold are adopted to achieve INS plastic injection molding production. The INS process is designed in groups. The mold has the advantages of simple structure, the design is ingenious and novel, can achieve an INS process for the handrail products producing high yields, provide the reference for the production of similar plastic parts.
