鼠標(biāo)上蓋注塑模的CAD/CAM
摘要：塑料工業(yè)是當(dāng)今世界上增長(zhǎng)最快的工業(yè)門(mén)類(lèi)之一，而注塑模具是其中發(fā)展較快的種類(lèi)，因此，研究注塑模具對(duì)了解塑料產(chǎn)品的生產(chǎn)過(guò)程和提高產(chǎn)品質(zhì)量有很大意義。
在注塑產(chǎn)品開(kāi)發(fā)中，模具的設(shè)計(jì)和制造決定塑料件的質(zhì)量和成本。綜觀國(guó)內(nèi)外先進(jìn)制造技術(shù)的現(xiàn)狀和發(fā)展，不難看出數(shù)字化制造技術(shù)是先進(jìn)制造技術(shù)的核心技術(shù)。隨著制造業(yè)的國(guó)際化，中國(guó)正逐漸成為制造業(yè)大國(guó)，
 本文探討了基于Mastercam平臺(tái)實(shí)現(xiàn)注塑模具CAD／CAM的方法和途徑，并以鼠標(biāo)上蓋為例，實(shí)現(xiàn)了注塑模具CAD／CAＭ過(guò)程。利用Mastercam軟件提供CAM數(shù)控加工模塊，完成了數(shù)控加工的全過(guò)程。本文詳細(xì)介紹了注射模具澆注系統(tǒng)、溫度調(diào)節(jié)系統(tǒng)和頂出系統(tǒng)的設(shè)計(jì)過(guò)程，鼠標(biāo)上蓋零件的結(jié)構(gòu)及工藝性，確定該塑件的注塑成型方案并進(jìn)行了注塑模設(shè)計(jì)方面的相關(guān)計(jì)算。CAD／CAM技術(shù)在模具行業(yè)中的應(yīng)用,大大減少了模具設(shè)計(jì)制造的周期，取得了顯著的經(jīng)濟(jì)效益，從根本上改變了傳統(tǒng)的模具生產(chǎn)方式。
 本文介紹了CAM技術(shù)在鼠標(biāo)上蓋注塑模具制造的NC加工中的應(yīng)用過(guò)程,包括曲面建模、加工路徑的選擇、刀具軌跡計(jì)算等，并對(duì)該套模具NC加工編程的特殊性及其工藝處理作了分析。本文主要介紹了Mastercam模塊的作用、加工能力和特點(diǎn)以及Mastercam加工類(lèi)型和加工工藝簡(jiǎn)介，并用Mastercam實(shí)現(xiàn)仿真加工。

The Design Of The Mouse-up-CAD/CAM
Abstract：Now the plastics industry is one of the growing quickest industry classes in the world, but the injection mold is develops the quick type. Therefore, There have biggist significance to research injection mold to understood that the plastic of production process and improve the product quality.A comprehensive survey of modern manufacturing technology indicated, that the digitized manufacturing is the key technique of advanced manufacturing technology．Our country is becoming a big factory.
 Based on Mastercam，the author present the method for Mastercam to achieve mould　CAD/CAM, and take the mouse-up as an example, describe the process of UG mould CAD/C AM in detail．The authors complete the NC manufacturing of mold’s core in Mastercam software．This design introduced the cold flow channel injection evil spirit mold pours the system, the temperature control system and goes against the system the design process, the analyzing of the structure and crafts of the mouse-up shells, deciding the way of the injecting and doing certain calculation relating to the injecting-mold. The using of CAD/CAM technology in mold industry decreases the time of mold-making with the result of increasing economies efficiency and ultimately exchanging the mode of traditional model-making．
 The application procedure of CAM in the mouse-up injection mold NC manufacturing is introduced in the paper．The procedure includes surface modeling, manufacture path selection, tool path calculating．An analyses of the characteristic of NC program and the dispose of technics about the　mouse-up-mold is made. The article mainly introduce the friction、capacity and term of Mastercam and manufacturing types and technics of  Mastercam， has stress on the integration of the core of the mouse-up-mould，and realize its emulation．
