| 摘要：本文将以熨斗外壳模具设计，论述相关注塑模具的关键问题和优势。该产品是配套件的主要零件，是采用塑料成型的，外观表面质量要求较高，外形不允许留下有明显的痕迹，对塑料材料的性能分析，熨斗外形的设计和建模，根据塑件的基本形状和尺寸如搜，合理选择注射的成型方法。着重解决模具结构设计合理，排气性要好，要求成型后尽可能达到精度要求，要考虑成型过程中的变形。最佳成型方法的选择，模具设计并进行理论分析。根据具体尺寸校核注塑模具以及注塑机的有关尺寸，并对工艺参数进行核定和计算。之后进行初步的审核对所存在的问题进行确定和修正，然后绘制模具总装配图，按装配图绘制成型零件及所有需要加工的零件工作图，同时考虑零件的加工工艺。编制模具工作零件的机械加工工艺性是，了解模具的加工流程，加工工艺，学会分析确定浇注系统和分型面，进行模流分析，来确定最佳的浇注系统。在这次设计过程中充分利用课本中的理论，严格按照模具设计的步骤，查阅相关模具参数以及相关机械手册，对塑件工艺性分析，分型面确定、成型零件设计、型腔数量确定、浇注系统设计等。完成一整套二文、三文模具零件图、总装图，完成说明书。35861 毕业论文关键词：注塑模；烫斗外盖板；斜顶；顶针。 The iron shell molding process analysis and die design Abstract: This paper will take the iron shell mold design, injection mold related key problems and advantages. This product is the main parts of auxiliary, is to use the plastic molding, high surface quality requirement of appearance, appearance is not allowed to leave have obvious marks, the performance analysis of plastic material, iron appearance design and modeling, according to the basic shape and size of plastic parts, such as search, selection of injection molding method. To solve the mould structure design is reasonable, the exhaust is better, after molding as far as possible to achieve accuracy requirements, want to consider the deformation in the process of forming. Best molding method choice, mould design and theoretical analysis. According to the detailed dimension checking relevant dimensions of injection mold and injection molding machine, and for verification and calculation of process parameters. After a preliminary review to identify the problems and correct, and then draw die general assembly drawing, according to the assembly drawing work molding parts and all the required processing of parts figure, at the same time considering parts processing technology. Preparation of the machining of the mould parts manufacturability is, understand mould processing process, processing technology, learn to analysis to determine the gating system and parting surface, mold flow analysis, to determine the best gating system. Make full use of the book of theory in the design process, in strict accordance with the mold design steps, refer to related mould parameters and mechanical manual, for plastic parts manufacturability analysis, determine the parting surface design, molding parts, the determination of cavity quantity, gating system design, etc. Complete set of 2 d and 3 d mold part drawing and assembly drawing, complete specification。 Key words: Injection mold; Iron plate; Inclined top; Thimble. 目 录 1 绪论 1 1.1 引言 1 2 结构设计 4 2.1 塑件的分析 4 2.2 熨斗外壳工艺分析 6 3 材料的选择 7 3.1 分析制件材料使用性能 8 3.2 分析塑料工艺性能 8 4 确定塑料成型方式及工艺过程 10 4.1 成型工艺规程 10 (责任编辑：qin) |
