摘要

塑料工业的飞速发展，对注塑模具的设计与生产提出了质量好、制造精度高、研发周期短等越来越高的要求，能否适应这种需求已成为模具生产企业发展的关键因素。CAD/CAE/CAM技术的应用对我国模具工业的发展起到了重要的推动作用。本文介绍了塑件松花江P-L型组合仪表罩的成型工艺，及模具成型结构对塑件质量的影响，总装结构的设计、模具成型部分、顶出系统和浇注系统的设计。通过对模具结构方案、模具工作过程以及加工注意事项的详细分析与论述，力图让读者了解注射模的设计程序。通过思考，采用延迟开模侧抽及组合传动器方式，合理解决了动、定模上都有侧向抽芯及整体式传动器致使开摸行程过大的问题。

Abstract
 Some higher demands such as high quality, high precision, short time of R&D and so on were put forward since the rapid  development of plasticin dustry, whether they can adapt to these requirements has becoming an important factor for the development of molding producer. The application of CAD/CAE/CAM greatly promote  the development of molding industry in our count Introduce plastic molding technique of the Songhua River P-L type shapingcraft in this paper ,and give mould shaping structural influence on moulding a quality, assembly design , mould shaping part , carry system of producing and pour the systematic design of structure.  Through to particularly analyzing and discussing the mold’s plans and structures, working process and processing notices, try hard to let reader understand that inject designing program of the mold. Through thinking deeply, of working principle adopt delay make mould side release and make hammer mechanism actuator way up, reasonably solve , move , make mould have side direction smoke core and integral hammer mechanism actuator cause , turn on , touch journey too big problem rationally.
