手表托架注射模具设计(塑料模具)(包含任务书,外文翻译,论文说明书11000字,幻灯片ppt,17张cad图纸)
摘 要
本文的主要任务是注塑模具结构设计，内容包括塑料模具的工作原理及应用，塑件分析，模具的各零件设计以及总体设计。
大致的设计思路如下：通过所给塑件的具体分析，确定注塑机；根据所选的注塑机来确定型腔数量和布局；注塑模具的关键是分型面的设计，这关系到产品质量和模具的设计；浇注系统设计包括主流道设计、分流道设计、浇口设计和冷料穴设计；排溢系统设计保证填充效果；成型零件设计计算，保证产品质量和模具的加工制造；导向机构、定出机构、复位机构必须合理；冷却系统设计控制模具温度，影响塑件成型质量。
关键词：Auto CAD, 塑料，注射模，注射机。
Injection mold design of watches bracket
The main task of this paper is the structural design of injection molds, including plastic mold of the working principle and application of analysis of plastic parts, mold design and the overall design of the parts.
Rough design ideas are as follows: through the plastic parts to the specific analysis of injection molding machine; according to the selected cavity injection molding machine to determine the number and layout; injection mold is the key to the design surface, it relates to product quality and mold design; gating system design including the design of the mainstream, separate design, gate design and the design of cold-feed points; row overflow filling system design to ensure results; molding part design terms, to ensure product quality and mold manufacturing; oriented institutions, for institutions, reset must be reasonable; cooling system designed to control mold temperature, affecting the quality of molding plastic parts.
Key Words: Auto CAD, Plastic, Plastic injection mold, Plastic injection.
