摘要
 
   在中国，人们已经越来越认识到模具在制造中的重要挤出地位，认识到模具技术技术水平的高低，已成为衡量一个国家制造业水平高低的重要标志，并在很大程度上决定着产品质量，效益和新产品的开发能力。
   通模具按制造的产品分类，可以分为塑料模具（又分为注塑模具，铸压模具和吹塑模具），冲压模具，铸造模具，橡胶模具和玻璃模具等。其中尤以注塑模具和冲压模具用途广，技术成熟，占据的比重重大。经过对4"碗工艺的正确分析，设计了一模四腔的塑料模具。详细的叙述了模具成型零件包括型腔，型芯等设计，重要的零件的工艺参数的选择和计算，浇注系统，冷却系统以及其它结构的设计过程，模架的选择原则。

  In china, people tend to recognize the important tool in the manufacture of mould, recognizing the status of those technical skills, and has become a country level of the manufacturing industry, and a large extent on product quality, efficiency and the new product developing ability.
  Die by manufacturing the product category, can be divided into plastic molds ( also divided into injection mold, pressure casting mold and blow mold), stamping die, die casting, rubber molds and glass molds. Especially in the injection mold and die stamping uses, technology is mature, occupied by major. After the4" bowl of the correct analysis of the technology, designing a mold four cavity mold. A detailed description of the mold of molding parts includes a cavity, core design, an important part of the process parameter selection and calculation, pouring system, cooling system and other structural design process, the choice of mold principle. And the use of PRO / E Plastic Advisor ( Plastic Advisor ) on the finished design plastic mold of plastic flow analysis.
