【正文】 CFlow、 DYNAFORM、 Optris 和 MAGMASOFT 等 CAE 軟件。而模具制造是整個鏈條中最基礎(chǔ)的要素之一，模具制造技術(shù)現(xiàn)已成為衡量一個國家制造業(yè)水平高低的重要標(biāo)志，并在很大程度上決定企業(yè)的生存空間。浙江寧波和黃巖地區(qū)的“模具之鄉(xiāng)”；廣東一些大集團公司和迅速崛起的鄉(xiāng)鎮(zhèn)企業(yè)，科龍、美的、康佳等集團紛紛建立了自己的模具制造中心；中外合資和外商獨資的模具企業(yè)現(xiàn)已有幾千家。 關(guān)鍵詞 ： PROE 軟件 CAD 軟件出圖 澆注系統(tǒng) 脫模機構(gòu) 定距分型機構(gòu) Abstract II Abstract The designing methods of injection mould of the charger shell are mainly introduced in this pape .First analyzes the features of the mouse shell parts, including material properties, forming characteristic and condition, structural manufacturability, draw the plastic parts using PROE software, and choosing the molding equipment, CAD drawing, etc. Then introduces the mouse shell injection mold parting surface selection, the determination of cavity number and arrangement, and mainly introduces the gating system, molding parts, steering mechanism, demoulding mechanism, distance parting mechanism and the design of the cooling system. And then select the standard mould base and mould material and process parameters of injection machine related check. Finally, the paper expounds the working principle of mould, and the possible problems in the process of installation and debugging summary, analysis, and gives the corresponding solutions. This paper discusses on the mouse shell injection mold structure of junior type, namely the gating system setting and in different parts of parting surface of emergence, with one module and four cavities cavity layout, the use of push board parts will launch. Keywords: PROE software CAD drawing gating system demoulding mechanism distance parting mechanism 目錄 III 目 錄 摘要 ............................................................................................................................................
