摘 要

本文主要讲述对数码相机面壳进行模具设计的过程，通过对塑件的工艺分析，设计出塑料模具，并通过对模具设计与分类信息及产品材料的性能分析，初步选择注塑机。

这次设计是对数码相机面壳的注射模进行了设计研究。该塑件成品的表面要求一般沙面，但要求耐老化耐磨损，使用寿命较长。故在设计中选ABS（丙烯腈-丁二烯-苯乙烯共聚物），潜浇口以保证其外观要求。由于塑件有较复杂外形轮廓及内部结构，产品倒钩距离较长需做油缸斜抽芯,对模具结构型腔排布的限制和生产数量等生产成本综合考虑,确定在该设计中，型芯型腔为便于加工尽量使用镶嵌件，以减少生产成本，保证塑件制品的加工成型精度。同时，本设计在模具结构细节和其他动作原理方面作了较为详细的解释说明。最后结合模具的结构和标准零件的选用完成了整套模具的装配，对有关技术规范进行了全面校核，确保所设计的模具结构合理并能安全可靠的用于批量生产。本设计阐述了结合使用 Pro/E，AutoCAD 完成装配图，零件图。

Abstract

This paper focuses on the process of mold design of digital camera shell, through process analysis of plastic parts, design of plastic mold, and the performance of the die design and classification of information and material analysis, the preliminary selection of injection molding machine.

The injection mold is designed for digital camera shell was designed. The surface of the plastic product general requirements of sand, but aging resistance abrasion resistance, long service life. B. ABS in the design, to ensure the appearance of latent gate. Because the plastic parts with complex shape and internal structure, product barb longer need cylinder angle core pulling, limit the production quantity and production cost of mould structure cavity layout consideration, determined in the design, core and cavity to facilitate processing as far as possible the use of mosaic pieces, reduces the production cost, to ensure the machining precision of plastic products. At the same time, the design of the die structure details and other operation principle in detail explanation. Finally, the structure and mold standard parts to complete the assembly die package, on the relevant technical specifications and conducted a comprehensive check, to ensure that the design is reasonable and can be safely used for mass production. Described the design of the combined use of Pro/E, AutoCAD to complete the assembly diagram, parts diagram.
