中文摘要及關鍵詞 摘 要：本設計是頂塊塑料零件的注塑模具設計，在結合了傳統(tǒng)的機械設計后把CAD技術應用在注塑模具的設計上，在CAD系統(tǒng)實行了模型和注塑模具的設計。本文介紹了我國當前模具技術的發(fā)展狀況以及CAD在模具上的應用，其中包括AUTOCAD。主要的機械部分設計，其內容包括塑料注塑模具的工作原理及應用，設計準則。塑料注塑模的設計計算，包括模具結構設計，注塑機的選用，澆注系統(tǒng)的設計，動、定模，澆注系統(tǒng)，脫模機構，頂出機構，冷卻系統(tǒng)等設計等方面。如此設計出的結構可確保模具工作運行可靠。 關鍵詞：CAD；CAM；注塑模；工藝 英文摘要及關鍵詞 Abstract：This design is a top piece of plastic injection mold design of parts, when combined with traditional mechanical design after the application of CAD technology in injection mold design, implementation of the model in the CAD system and injection mold design. This article describes the current state of development of mold technology and CAD in the mold applications, including AUTOCAD. The main mechanical part of the design, which includes plastic injection mold working principle and application of design criteria. Plastic injection mold design calculations, including the design of the mold design, injection molding machine selection, gating system design, dynamic, fixed mold, pouring system, the release mechanism, the ejection mechanism, cooling system and other aspects. So design a structure to ensure reliable operation of the mold work. Keywords: CAD; CAM; injection molding; Process
