摘要
     塑料成型产品在我们的日常生活中随处可见。通过对塑件进行高温高压注射处理来获得塑件的具体结构,也称为塑料零件、塑料部件。其广泛应用于生活中的角角落落,特别是在电子仪器,电气设备,通信工具中。各种外壳,框架、结构、装饰等;注射机是制造塑料模具的主要生产技术和设备,在国民经济中占据重要的地位,模具技术也成为衡量一个国家产品制造水平的重要标志。塑料成型注塑是一个重要加工产品的方法,它主要用于热塑性塑料的成型。本次设计的是诺基亚手机外壳前盖注塑模具的设计,它是一个形状比较复杂的精密塑料零件,本文以注塑模具的相关知识作为依据,阐述了塑料注塑模具的整体设计。
    本文设计的内容就是诺基亚手机外壳前盖注塑模具，材料为PC，根据其结构形状特点以及通过对诺基亚手机外壳前盖成型工艺的正确分析，来设计出正确的诺基亚手机外壳前盖塑件。

ABSTRACT

    Plastic molding products are plastic as the main structural material. The processing of products.Referred to as the plastic parts.plastic molding products arewidely used.Especially in the electronic instrument electrical equipment ,communication tools ,etc to obtain a large number of applications . such as all kinds ofstress are shell stents structure decoration.Based process equipment as the main production of plastic products of plastic mold .occupies an important positionin national economy mould technology has also become to measure a national product manufacture level of important symbol.Injection molding plastic molding isan important method .it is mainly suitable for thermoplastic molding .and canbea complicated shape of precision plastic forming parts is the adsl surface hella a design model .This paper will be injection mold related knowledge as thebasis.the overall design process of plastic injection mould are expounded.
Design the content of this article is shell of plastic injection mould ,materials for PC .According to the shape of the structure characteristics and throughthe analysis of the right across the shell molding process,determine the overall distribution of cavity choose the parting surface determine the demoulding way .The design of gating system,etc.
Keywords：Plastic mold；injection molding； the parting surface
