Title Shampoo Flip CAD Design Of Injection Mold
Abstract
Plastic processing and molding technology have been getting more and more important with the widespread use of plastic, and plastic injection molding has been the most common way for polymer processing. Under the background, the structure of the plastic parts was analyzed and the mould was designed here. The design of the die structure was discussed and a set of solution was proposed. After that, it was improved and optimized step by step.
Based on mold design theory, the gate of the program was analyzed and compared by the Moldflow software. The cap mould was designed by using a top-down design approach. Firstly, the selection of injection machine, size of the mould, design of pouring channel were analyzed and calculated. And the analysis of unscrewing thread and ejecting plastic was the main emphasis. Finally, the die structure model and parts drawing were drawn with the Solidworks software.

1引言
1.1研究背景
随着人类科学技术的发展与不断提高，人们对日常用品轻便化的要求也逐步提高。塑料具有质量轻、比强度大、绝缘性好、成型生产率高和价格低廉等优点。塑料已成为金属的良好代用材料，出现了金属材料塑料化的趋势。注塑成型由于可以一次成型各种结构复杂、尺寸精密和带有金属嵌件的制品，并且成型周期短，可以一模多腔，大批生产时成本低廉，易于实现自动化生产，因此在塑料加工行业中占有非常重要的地位。[1]事实证明模具成型是其极佳的生产方式。
