摘要:模具是一种技术密集、资金密集型产品，在我国国民经济中的地位也非常重要。模具工业已被我国正式确定为基础产业，被称为“工业之母”。75%的粗加工工业产品零件、50%的精加工零件由模具成型，绝大部分塑料制品也由模具成型。如此选择了充电器外壳（上壳）注塑模具设计作为本次毕业设计的题目，以下是设计的主要的内容：
(1) 介绍了塑料模具发展的现状和发展趋势，阐述了塑料模具是现代社会经济发展不可缺少的和模具生产技术水平的高低是衡量一个国家产品制品水平高低的重要标志之一。
(2) 展示了塑件的3D建模图形；分析了塑件的工艺性，主要是根据塑件材料确定了收缩率和脱模斜度，对塑件结构分析确定了壁厚和精度。
(3) 介绍了本设计注塑成型工艺条件；用UG造型软件模型分析功能对塑件进行了质量属性的分析，通过塑件的质量属性初步选择了注塑机G54-S200/400，对此注塑机介绍了规格和性能。
(4) 主要介绍了模具结构的设计。首先对模具方案的论证，型腔数目的以及排列形式、分型面的确定；其次详细的介绍了浇注系统的设计，其中包括了主流道、分流道浇口的设计，然后对排气机构、冷料穴和拉料杆的设计，详细对零部件的尺寸进行了计算；最后介绍了推出机构和温度调节系统的设计
(5) 对注塑机一些参数的校核和标准模架的选择，校核了最大注塑量、锁模力、开模行程。最后对一些零件图和装备图的绘制。
(6) 对本设计的总结。主要对设计过程回顾，以及本设计的创新和不足之处的总结。

ABSTRACT:Mold is a technology-intensive product, capital-intensive industries in China’s national economy, the position are very important. Mould industry has been China formally identified as fundamental industry, known as "the mother of industrial". 75% of rough machining industry product parts, 50% of the machining parts by molds and most plastic products also by molds. So I chose Chargers Case mold design as the graduation design topic, the following is design of the main content:
(1) Introduced the plastic mould development status and development trend of plastic mold, expounds the modern social economic development is the indispensable and mould manufacturing technology level of measure of a national product products is one of the important signs of horizontal discretion.
(2) Shows the 3D modeling graphics molded parts; analyzes the technology of plastic parts, mainly is determined according to the plastics materials for shrinkage and draft, molded parts structure analysis identified wall thickness and precision.
(3) Introduced the design injection molding process conditions; Make casting 3d drawing using UG modeling software model analysis function of the plastic parts, through the analysis of the quality attributes the quality of plastic parts XS attribute preliminary chose injection, which ZY/500 - injection molding machine introduces specification and performance.
(4) Mainly introduces the design of die structure. First to mold cavity number scheme of the argument, arranged form, classification and determine the; Secondly the detailed introduces the design of gating system, including the mainstream way, the design of shunt way spruce, then to exhaust institutions, cold material feeding stem hole and pull the design of the size of the parts, detailed calculated; At last, the paper introduces the launch institutions and temperature control system design.
(5) Is some parameters for injection checking and standard formwork choice, here was checked injection quantity biggest, clamping force, open mold trip. Finally some parts of chart and equipment for drawing.
Finally this design is summarized. Mainly to the design process, and the design review innovative and deficiencies summary.
