毕业论文-电视遥控器外壳注塑模设计.doc

摘 要 本论文论述了遥控器外壳壳{0首先对电视机后罩塑料制件结构和成型工艺进行充分的分析，了解其整个成型过程，为模具设计提供参考数据，保证模具结构设计的合理性。然后确定型腔的数量和分型面，针对本塑件设计成型零件的型腔和型芯，确定合理的浇注系统和冷却系统,根据型腔的形状设计模具的温度调节系统，设计模具的合模导向机构和推出机构，通过塑件的尺寸选取模架，对模具中主要零件的制造进行工艺分析。最后完成整个模具的设计。 设计中对注射模结构设计的进行了工艺分析，并进行相关的计算，设计模具的最佳方案、总体结构设计、主要零件结构设计及相关参数的校核。该模具结构设计巧妙，，塑件达到技术要求。 模质量的好坏直接影响塑料制品的质量和成本。模具设计的合理与否，直接关系到塑件能否成型，塑件质量能否满足要求，是否经济，模具型腔的形状，尺寸，表面粗糙度，浇口的形式，大小，位置，分型面的位置，排气槽的设置，脱模机构的形式，顶出位置，模具温度的控制对塑件的尺寸精度，形位精度，表面粗糙度，以及塑件的物理性能，机械性能，电性能，内应力大小，各向同异性，外观质量，气泡，凹痕，银纹，变形等都产生着直接的十分重大的影响 对模具的整体设计用到了功能强大的UG软件，以及简单方便的CAXA。 关键词：遥控器外壳；塑料注射模具；工艺分析；结构设计； Abstract This paper describes a remote shell plastic injection mold and process analysis. The first full analysis of the structure and forming process of the remote shell plastic parts ,to understand the molding process, mold design to provide reference data to ensure the rationality of the design of the mold structure . Then determine the number of the cavity and parting surfaces. The plastic parts design forming part of the cavity and core, to determine a reasonable level of casting system and drain overflow system , temperature control system according to the cavity shape of mold design , mold design co-mold-oriented institutions and the introduction of institutions , and select the size of the pastic parts mold, the main parts of the mold manufacturing process. To finalize the mold design . The design of the structure of the injection mold design process and the associated calculations, the best solution for mold design, the overall structural design, structural design of the main parts and related parameters checking. The structural design of the mold is simple and clever, smooth curves, more fashionable, lower manufacturing costs, plastic parts of the basic technical requirements. The quality of the injection mold a direct impact on the quality and cost of plastic products. Mold design is reasonable or not, is directly related to the plastic Can mold, plastic parts can meet the quality requirements, Whether econ
