3168 滅火器注塑模設(shè)計,滅火器,注塑,設(shè)計 摘要系統(tǒng)介紹了塑件的成形工藝及模具成型結(jié)構(gòu)對塑件質(zhì)量的影響分析，澆注系統(tǒng)的設(shè)計，模具成型部分和總裝結(jié)構(gòu)的設(shè)計。介紹了滅火器注塑模具設(shè)計時要注意的要點，并較多的考慮了模具結(jié)構(gòu)的調(diào)整性、易更換性及模具成本。從控制制件尺寸精度出發(fā)，對滅火器注塑模的各主要尺寸進行了理論計算，以確定各工作零件的尺寸，從模具設(shè)計到零部件的加工工藝以及裝配工藝等進行詳細的闡述，并應(yīng)用 CAD 進行各重要零件的設(shè)計。 關(guān)鍵詞： 模具設(shè)計；塑件成型；工藝性分析；澆注系統(tǒng)Injection Mold for fire extinguisherAbstractThe molding process of plastic parts, the effect analysis to plastic parts quality caused by molding structure, as well as the casting system design, partial and general design of mold moulding introduced respectively. The critical points of mold for plastic design are introduced, and the adjustable character of molding structure、exchange character as well as the molding costs are all considered farther. Starting from controlling dimensional accuracy, the theoretical calculation to the main dimensions of injection molding are carried out so as to determine the size of different parts, the molding design and the process of parts as well as assembling process and etc of injection molding are stated in details.Key words: mold design; plastic parts moulding; process analysis; casting system;目 錄緒 論……………………………………………………………………………… 1第 1 章 模塑工藝規(guī)程的編制…………………………………………………… 31.1 塑件的工藝性分析………………………………………………… 31.2 計算塑件的體積和質(zhì)量…………………………………………… 41.3 塑件注塑工藝參數(shù)的確定……………………………………………4第 2 章 注塑模的結(jié)構(gòu)設(shè)計……………………………………………………… 52.1 分型面的選擇………………………………………………………… 5 2.2 確定型腔的排列方式………………………………………………… 52.3 澆注系統(tǒng)設(shè)計………………………………………………………… 62.4 抽芯機構(gòu)設(shè)計………………………………………………………… 6 2.5 成型零件結(jié)構(gòu)設(shè)計………………………………………………… 8第 3 章 模具設(shè)計的有關(guān)計算……………………………………………………… 93.1 型腔和型芯工作尺寸計算…………………………………………… 93.2 型腔板的三維尺寸確定……………………………………………… 11第 4 章 模具加熱及冷卻系統(tǒng)的計算……………………………………………… 13第 5 章 模具閉合高度及注塑機有關(guān)參數(shù)的校核 ……………………………… 145.1 模具閉合高度…………………………………………………………… 145.2 注塑機有關(guān)參數(shù)的校核………………………………………………… 14第 6 章 模具的裝配、試模與維修………………………………………………… 156.1 裝配…………………………………………………………………… 156.2 試?！? 156.3 模具的維修…………………………………………………………… 16第 7 章 主要零件加工工藝規(guī)程的編制 …………………………………………… 17第 8 章 結(jié) 論…………………………………………………………………………19致 謝………………………………………………………………………………… 20參考文獻……………………………………………………………………………… 21
