【正文】 ustrial production, in the modern industrial production, 60%～ 90% of industrial products need to use mold, the mold industry has bee the foundation of industrial development, research and development of many new products are largely dependent on mold. Therefore, the research and the development of mold technology are significant to promote the development of the national economy. This paper pletes a series of injection mold design process and designs the plastic mold with side core pulling based on the structural features and technical requirements of camera cover. The software of UG and Moldflow are used to analyze the mold. Plastic parts are analyzed in the design process, at the same time, the size and structure of the plastic parts are determined. The design and manufacturing of slanted guide pillar, mould core, cavity and other parts are introduced in detail, as well as the injection molding machine is chosen correctly. Keywords camera cover injection mold side core pulling Moldflow 南京工程學(xué)院畢業(yè)設(shè)計(jì)說(shuō)明書(shū)（論文） 第 III 頁(yè) 目 錄 前言 ....................................................... 1 第一章 塑料模的功能
