【正文】 forms high benefit, high efficiency precision casting metal presses the mold formation technology is at present takes shape the nonferrous metal structural element important formation technique, the metal presses the mold is the pression casting formation important craft mold took the important craft equipment, in industry sectors and so on the consumable, electric appliance electron, automobile, airplane manufacture, holds the pivotal industry product ponents rough machining 75%, the precision work 50% and the plastic parts 90% are plete by the mold. The mold makes the technique may divide into forging, the heat treatment, the machining, the surface treatment and the assembly and so on, in which take machining as the main processing machining may divide into the cutting engine bed processing, the pliers processing and the special processing roughly and so on, the usual mold ponents processing craft route should follow the ordinary machinefinishing craft generally the basic the mold ponents the processing to be possible to divide into the template processing, Kong Jikong roughly is the processing, the formation ponents processing and so on, should act according to its own actual situation choice appropriate processing method to the different die body. Along with the world advance in technology and the machine tool industry development, the numerical control engine bed took the machine tool industry the mainstream product, has bee the realization equipment manufacturing industry modernization the essential equipment, is the national defense war industry equips the development the strategic numerical control engine bed capacity and the performance capability height, is weighs a national synthesis strength the important up the development numerical control engine bed industry also is our country equips the manufacturing industry development the reality numerical control processing is modern technique of manufacture typical representative, the numerical control technology is the machinefinishing automation foundation, is the numerical control engine bed core technologies, its horizontal height relates the national strategy status and manifests the national prehensive national strength the level.In this paper, the specific parts from the process of analyzing the level of detail appropriate to introduce a pression casting, the selection of pression machine, pression mold design.【Key word】The pression casting mold、Mold、the numerical control technology【Dissertation type】A theory and practice and research目 錄第1章 零件工藝性分析 零件工藝性分析………………………………………………………………1第2章 壓鑄機型號的選擇 壓鑄機選用原則………………………………………………………………3　　　 按鎖模力選擇壓鑄機…………………………………………………………3 按壓室充滿度選擇壓鑄機 ……………………………………………… 4第3章 確定模具結構 確定分型面……………………………………………………………………6　　　 確定壓鑄件在模具中的位置…………………………………………………6 澆注系統(tǒng)的確定 ……………………………………………………………7 成型零件的設計 ……………………………………………………………7 模架結構 ……………………………………………………………………14 推出機構設的計 ……………………………………………………………16 澆注系統(tǒng)及排溢系統(tǒng)的設計 ………………………………………………17第4章 繪制壓鑄模裝配圖…………………………………………………………………19第5章 繪制模具零件圖……………………………………………………………………20第6章 典型零件機械加工工藝規(guī)程 導套機械加工工藝過程……………………………………………………22 斜銷數控加工程序…………………………………………………………23致 謝 ……………………………………………………………………………………24參考文獻　 ……………………………………………………
