【正文】 the die design and classification of information and material analysis, the preliminary selectio n 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 plex 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 plete the assembly die package, on the relevant technical specifications and conducted a prehensive check, to ensure that the design is III reasonable and can be safely used for mass production. Described the design of the bined use of Pro/E, AutoCAD to plete the assembly diagram, parts diagram. Keywords: digital camera shell, Pro/E, plastic mould, design 目 錄 摘要 Abstract 第一章 緒論 ............................................................................................
