双色高光成型塑件的结构设计技术

摘要

According to the requirements of double-injection and high gloss plastics injection on structure design, the design methodology of structure with double color and high gloss surface including the main struc ture and join way, shut-off design, bosses, ribs, fillets, hole, etc, were been studied based on conven tional design method. The research lead to the conclusion that three main rules-correspondence of structure, sturdiness of connection and uniformity of wall-thickness, should be followed based on the outstanding charac teristic of double-decker and high-gloss surface of high gloss double-injection plastic part. Finally study used a LCD TV front shell and electrical appliance shell as an example to illustrate structure design of double color high gloss plastic products.%根据双色注塑和高光注塑成型对塑件结构的双重要求,基于和普通塑件结构设计方法的对比,针对双色高光塑件的整体结构、连接方式、防溢设计及凸起、加强筋、圆角、孔等进行研究.结合双色高光塑件的双层结构及表面高光的突出特点,得出其结构设计需遵守结构协调、黏结牢固及壁厚均匀三项原则.并以某液晶电视机前壳和电器外壳结构设计为例,对双色高光塑料制品的结构设计做了具体阐述.
