打蛋機外殼注塑模具設計（全套含CAD圖紙）,打蛋機,外殼,注塑,模具設計,全套,cad,圖紙 摘??要 ? 注射成型是熱塑性塑料成型的主要方法之一，可以一次成型形狀復雜的精密塑件。本課題就是將打蛋機左殼作為設計模型，將注射模具的相關知識作為依據(jù)，闡述塑料注射模具的設計過程。? 通過對工件的正確分析，設計了一副一模兩腔的塑料模具。確定了分型面、澆注系統(tǒng)等，選擇了注射機，計算了成型零部件的尺寸。采用側(cè)澆口，利用直導柱導向，推桿頂料,斜頂桿和彈簧完成脫模及對模具的材料進行了選擇。如此設計出的結(jié)構(gòu)可確保模具工作運用可靠。最后對模具結(jié)構(gòu)與注射機的匹配進行了校核，并用CAXA繪制了一套模具裝配圖和零件圖。 關鍵詞：塑料模具；注射成型；模具設計 Beat-egg machine left shell injection mold CAD/CAM Abstract：Injection molding is one of the main methods of thermoplastic plastic molding, molding can be a complex shape of precision plastic parts. This topic is to beat egg machine left shell as a design model, the injection mold-related knowledge as the basis, the plastic injection mold design process.Through the correct analysis of workpiece, a pair of mould with two cavities was designed. The parting surface, gating system have been determined, the choice of injection machine, has calculated the formation spare part size. The side gate, using straight guide column, putting the material, inclined push rod and spring completed stripping and material of the mould were researched. So the structure is designed to ensure reliable mould work. Matching the mold structure and the injection machine was checked, and a set of CAXA drawing die assembly drawings and part drawings.
