基于proe的鼠標上蓋模具畢業設計論文
摘 要
鼠標上蓋是流線形結構,使用二維繪圖難以描述,本課題采用Pro/E軟件對鼠標上蓋制品及模具進行了三維造型,采用Pro/E的數值模擬技術和經驗設計計算相結合的方法優化設計,同時仿真了塑料熔體在型腔內的充模流動以及冷卻分析過程,預測了缺陷產生的臨界條件,優化了工藝方案及工藝參數,降低了缺陷出現的可能性。利用參數化實體造型的方法,為更加高速、快捷的造型、生產提供了一種切實可行的辦法。生成的模型數據可以直接導入數控機床進行三維加工。

Abstract
The top cover of mouse is streamline. So it is difficult to describe by two-dimensional drawing. The product and mold of the top cover of mouse were 3D designed by Pro/E software. An optimized design was made by numerical simulation techniques of Pro/E and experience. The plastic melt flow and cooling process were simulated for forecasting critical conditions of errors. Technical parameters and processes have been optimized. The possibility of errors was reduced. Solid parameters are used which provide a practical approach for more rapid and efficient forms .The model data can be used directly for numerically controlled machine tools with 3D processing.
