     塑料成型制品是以塑料为主要结构材料经成型加工获得的制品，又叫做塑料制件，简称塑件。塑料成型制品应用广泛，特别是在电子仪表、电器设备、通信工具等方面获得大量应用。如各种受力不大的壳体、支架、结构件、装饰件等；作为塑料制品的主要生产基础工艺装备的塑料模具，在国民经济占有重要的地位，模具技术也已成为衡量一个国家产品制造水平的重要标志。注射成型是塑料成型的一种重要方法，它主要适用于热塑性的成型可以一次成型形状复杂的精密塑件，本次设计就是将电视遥控器外壳作为设计模型，将注塑模具的相关知识作为依据，阐述塑料注塑模具的整体设计过程。
 本文设计的内容就是电视遥控器外壳注塑模具，材料为ABS，根据其结构形状特点以及通过对电视遥控器外壳成型工艺的正确分析，确定型腔的总体布局，选择分型面，确定脱模方式，设计浇注系统等；同时本文对注塑模具进行简要介绍，对注塑模具中的主要零件进行设计计算，在设计过程中着重考虑其生产实际中的经济性和合理性。
关键词：注塑模具； 注射成型； 分型面
 

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 ABS .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
