内凸缘矩形盒塑料模具设计与制造
摘要
本文首先简要的概述了塑料模在社会领域中的作用及其以后的发展方向，点明模具设计的重要意义。然后依据工件图进行工艺性分析，进而确定了设计方案，计算出模具工作部分的尺寸，设计出工作零部件；然后依据设计要求选择出各个标准零部件，然后设计出模具的总装配图。在设计中，最重要的就是设计方案的确定、坯料的计算和选取以及工作零部件的设计，这是设计的关键，这些设计的正确与否直接关系到成本的高低和设计模具能否正常工作。因此,模具的设计与制造能把我们所学知识从新巩固一遍。
关键词：模具设计与制造、CAD软件、工艺性分析。
Head modelling and mold design of drain pipe
Abstract
This text the brief plastic role in social field of mould of summary and developing direction afterwards at first, point out in the important meaning of mold design. Then carry on the craft to analyse according to the work piece picture , and then has confirmed the design plan , calculate out mould work some size , design the job spare part; Then choose each standard spare part according to the designing requirement , then design the total installation diagram of the mould . In the design, the important one is sureness of the design plan , calculation and choosing and working the design of the spare part of the blank the most, this is the key to designing, whether these ones that are designed involve directly or not correctly whether the level of the cost and design mould could work normally. Therefore, the mold design and the manufacture can study us the knowledge to be anew consolidated.
