· 摘 要 模具制造技术迅速发展,已成为现代制造技术的重要组成部分。本设计介绍了塑料注射模具的设计与制造方法。该注射模采用了1模2腔的结构。根据塑件的结构,选用了两侧带有侧抽芯机构的两板模,运用斜导柱完成塑件的侧抽芯,采用侧浇口完成进料。在整个设计过程中,查阅了大量的参考数据,深入分析设计内容,包括塑件成型工艺性分析;拟定模具结构形式;注射机型号的确定;浇注系统形式和浇口的设计;成型零件的结构设计和计算;模架的确定和标准件的选用;合模导向机构的设计;脱模推出机构的设计;侧向分型与抽芯机构的设计;冷却系统的设计。由于抽芯距离较短,为了使模具结构简单,采用斜导柱侧抽芯方式,并对模具的材料进行了选择。如此设计出的结构可确保模具工作运用可靠。最后对模具结构与注射机的匹配进行了校核。 通过该塑料模具的设计使自己对塑料模具的设计流程有了更深一层次的认识。 关键词:塑料;注射模具;设计;侧抽芯;斜导柱 ABSTRACT The die making technology rapidly expand, has become the modern technique of manufacture the important component.This design introduced the plastic injects molds design and the manufacture method. This injection mold has used 1 mold 2 cavity structures. According to the structure of the plastical piece chose to use the mold with two sidecores. make use of inclined lead pillar completion side core-pulling of the plasticalpiece and adopt side gate completion injection .Checked a great deal of reference in the whole design process, thorough analysis the design contents, include usage Proe software to carry on wallthinckness and draft analysis for the product;Draft the mold structure form;The assurance of injection machine model ;design of injection system and gate;Model structure design and calculation of mold parts; The assurance of mold base with standard piece of choose to use;ejector organization‘s design;The design of side core ejector ‘s organization;The design of cooling system. As the core pulling shorter distances, in order to enable Die simple structure, using bevel-side core-pulling, also mold the material of choice. The design of such a structure can be used to ensure reliable die. Finally, the injection mold structure and the matching machine was calibrated. Through the design process of plastics mold makes me have more deep one layer understanding of the design process to the plastics mold.
