【正文】 中座的鑄造工藝設計 摘 要 ： 本文通過對中座的結構、材料、技術要求等的分析， 在此基礎上 設計出符合該零件的 樹脂砂 砂型鑄造工藝方案。 根據鑄造工藝手冊和相關資料，確定加工余量、澆注位置、分型面、分模面和鑄造縮率等相關參數，并確定采用無冒口澆注方案；根據初步的鑄造工藝設計，確定型芯結構、大小和位置；采用鑄造 CAE，模擬凝固過程中鑄件的熱節(jié)和縮松傾向，設計冷鐵的位置和大小以及冒口類型和大??；根據鑄 造工藝手冊，設計鑄件的澆注系統，基于半封閉半開放澆注系統的設計方法，設計內澆口、橫澆道和內澆口的尺寸和布置；最后對鑄件的凝固過程和流動過程進行計算分析，可視化觀察了鑄件的充型過程，驗證了澆注系統的設計。 設計出了生產其所要用的 模樣模板，芯盒 等 鑄造工裝圖 。 關鍵詞： 結構分析，工藝設計，模擬分析，工裝設計 JIANGSU TEACHERS UNIVERSITY OF TECHNOLOGY 本 科 畢 業(yè) 設 計（ 論 文 ） Of the seat in the casting process design Abstract: This article through to in the structure of the bridge, the material, the technical requirements for analysis, based on this design meets the ponents of the resin sand sand casting process scheme. According to the casting process manual and related material, sure machining allowance, pouring position, parting surface, parting surface and casting shrinkage and related parameters, and sure to use without rising head pouring scheme, According to preliminary casting process design, fixed type core structure, size and position。 The casting CAE simulation, casting during solidification of hot shrinkage section and tendency, design cold iron and take the size and location of the mouth type and size , According to the manual casting process, design casting gating system, based on the semiclosed half open the design of gating system method, ingate design, horizontal runner and ingate size and layout , The last of the castings solidification process and flow process of calculation and analysis, and visualization observed the casting mould filling process, and verifies the the design of gating system , Design the production with the appearance of the template, and core boxes and other casting tooling figure .
