照相機(jī)某零件支架注塑模具設(shè)計(jì)
摘要
模具是工業(yè)生產(chǎn)的基礎(chǔ)工藝裝備,也是發(fā)展和實(shí)現(xiàn)少無切削技術(shù)不可缺少的工具。它在工業(yè)生產(chǎn)中使用極為廣泛,是當(dāng)代工業(yè)生產(chǎn)的重要手段和工藝發(fā)展方向,許多現(xiàn)代工業(yè)的發(fā)展和技術(shù)水平的提高,在很大程度上取決于模具工業(yè)的發(fā)展水平。因此,模具技術(shù)發(fā)展?fàn)顩r及水平的高低,直接影響到工業(yè)產(chǎn)品的發(fā)展。也是衡量一個(gè)國家工藝水平的重要標(biāo)志之一。
本次畢業(yè)設(shè)計(jì)的題目是照相機(jī)某零件支架注塑模具設(shè)計(jì)。本文主要論述了塑料注射模的基本原理和設(shè)計(jì)過程,并著重講述了充電器外殼注射模的設(shè)計(jì)過程。首先,講述了模具的作用和國內(nèi)外的發(fā)展?fàn)顩r及其發(fā)展方向。然后論述了方案的選擇和確定。再次對(duì)于所確定的方案給出了詳細(xì)的設(shè)計(jì)過程和計(jì)算過程,最后還對(duì)所設(shè)計(jì)的模具進(jìn)行了經(jīng)濟(jì)性可行性分析。
總的來說,所設(shè)計(jì)的這套模具經(jīng)濟(jì)合理,可行性強(qiáng),生產(chǎn)方便,是一套實(shí)用性較強(qiáng)的模具。

The camera bracket a parts injection mold design
Abstract
The molding tool is a foundation craft that industry produce to equip, it also a development with realizes the little having no slice the indispensable tool in the technique of cutting .It is in industry produce the usage is extremely extensive, it an important means that contemporary industry produce to develop the direction with the craft, many modern industrial developments with horizontal exaltation in technique, be decided by the industrial development in molding tool level to a large extent. Therefore, moldings tool technique development condition and horizontal and high and low, affect the development of the industry product directly. Too is to measure the one of the horizontal and important markings in a national craft.
The graduation project title is the camera bracket a parts injection mold design., this text discussed primarily the plastics injects the basic principle of the mold with design the process, combining to emphasize to relate the Chargers shell inject the design process of the mold. First, related the function of the molding tool with domestic and international development condition and its development directions. Then discussed the choice of the project with certain. Returns a project for making sure give a detailed design process with compute process; very much again the molding tool to design to preceded the economic viability assessment.
Total to say, a this set of molding tools for designing economy reasonable, the possibility is strong, producing the convenience, it a stronger molding tool in a set of function.
