基于ProE的接水盒注塑模具设计

本科毕业设计(论文)通过答辩 摘 要 注射成型是热塑性塑料成型的主要方法之一, 可以一次成型形状复杂的精密 塑件。本次设计中,主要运用到了所学的注射模设计以及相关机械设计等方面的 知识。分析了一副注射模的一般设计过程,即注射成型的分析、注射机的选择及 相关参数的校核、模具的结构设计、注射模具设计的有关计算、模具总体尺寸的 确定与结构草图的绘制、模具结构总装图和零件工作图的绘制等。设计主要包括 成型位置及分型面的选择,模具型腔数的确定及型腔的排列布置和流道布局,还 有浇口位置的选择,模具工作零件的结构设计,抽芯机构的设计,浇注系统的设 计,推出机构的设计,斜导柱的设计等。设计过程主要利用了 Pro/E 进行三维零 件的绘制并根据设计计算绘制出模具的型芯和型腔以及基本模架等, 然后用 Auto CAD 进行二维装配图和零件图的绘制,最后通过对整体结构的校核,提高了其 稳定性和可靠性。 关键词:接水盒;注塑模;ABS 塑料 III 本科毕业设计(论文)通过答辩 Abstract Injection molding is one of the main methods for thermo plastics, and it can once-form delicate plastic members with sophisticated shape. In this design, the knowledge of injection mold design and related mechanical design are mainly used. The design process of a injection mold is analyzed, that is, the analysis of injection molding, the selection of the injection molding machine and the check of the related parameters of it, the structural design of the mold,, the related calculation of the injection mold design, the determination of the overall size of the mold and the drawing of the sketch, the drawing of the assembly diagram of the mold structure and the parts diagram, and so on.. the design includes the choice of the molding location and the parting surfaces, the determination of the number of the mold cavity, the layout arrangement and the runner layout of the cavity, as well as the choice of the gate location, the structural design of the mold parts、 the core-pulling mechanism、 the gating system、the ejection mechanism and so on.Design process mainly uses the Pro/E 3D part drawing and according to the design drawing of the mould core and cavity, and basic mold rack and so on, then use Auto CAD 2D assembly drawing and parts drawing, at last, by check, for the whole structure to improve its stability and reliability.
