【摘要】：在注塑产品的生产过程中,注塑模具直接影响注塑产品的外观,同时也决定了注塑产品的生产成本和研发周期。近几年随着科技不断进步,注塑行业发展迅猛,注塑模具的设计、加工、组装与调试有更高的要求。本论文基于NC电气盒底座进行一模多腔注塑模具结构设计,进行了NC电气盒底座注塑模具的三维设计,对电器盒底座进行结构分析和材料选择,查阅相关资料合理选择注射机并对注射机各项关键参数进行校核。对模具的主流道、定位圈、分流道、浇口、冷料穴和拉料杆等浇注系统进行设计,还对凹凸模结构、工作尺寸、标准模架、合模导向机构、推出机构进行设计。利用Moldflow模流分析软件,仿真完整注塑过程,建立NC电气盒底座模型,对模型进行网格的划分、有限元分析、模型材料选择。采用一模四腔设计,创建模腔、浇注系统及冷却系统回路,通过数据结果分析,确保了模具设计满足充填、冷却和顶出各阶段注塑要求。本文通过NC电气盒底座注塑模具设计实例,采用理论分析与有限元仿真相结合的方法,围绕注塑加工过程中涉及到的产品结构工艺性参数、注塑机性能参数,进行了系统、深入的分析与研究。这为实际生产过程中工艺参数的合理选取、指导注塑模具优化设计、缩短注塑模具的设计周期具有重要的现实意义。本论文的主要内容包括:1.对NC电气盒底座塑件结构进行分析,确定了注塑件所用到的材料、型腔数量,并对注射机工艺参数进行校核,包括最大注塑量、注射机压力、锁模力和模具相关尺寸的校核。2.参照模具的设计原理,基于UG对注塑模具结构进行分析。对主流道、分流道、成型零部件、导向机构和推出机构进行合理优化。采用模流分析软件对塑件注塑过程进行仿真分析,减少了传统模具组装和调试过程中试模、修模的工作量,改善模具生产工艺,降低了研发成本。通过模流软件数据结果分析,对模具方案的可行性进行评估。
[Abstract]:In the production process of plastic injection molding products and injection mold injection directly affects the appearance of the product, but also determines the injection production cost and development cycle. In recent years, with the development of science and technology, the rapid development of injection molding industry, injection mold design, processing, assembly and commissioning have higher requirements. In this paper a multi cavity injection mould structure design of NC electrical box base based on the 3D design of NC electrical box base of injection mold, the electrical box base to analyze the structure and material selection, access to relevant information, reasonable selection of injection machine and check the key parameters of injection machine. The main channel of the mold positioning ring runner design, gate, cold material and pulling rod and gating system of die structure, work size, standard mold, mold oriented mechanism, pushing mechanism design. Using Moldflow mold flow analysis software A complete simulation of injection molding process, the establishment of NC electrical box base model, grid division model, finite element analysis, the choice of model material. The design of the first mock exam to create four cavity, cavity, pouring system and cooling system, through the data analysis of the results, to ensure that the design meets the mold filling, cooling and ejection of the stage of injection molding requirements. Through NC electrical box injection mold base design example, adopting the methods of theory analysis combined with finite element simulation, the process of product structure around the injection molding processing parameters involved in the process of injection molding machine, the performance parameters of the system, in-depth analysis and research. The process parameters in the actual production process the reasonable selection of guidance, injection mold design optimization, has important practical significance to shorten the design cycle of injection mold. The main contents of this thesis include: 1. of the NC electric box base structure of plastic parts. For analysis, determine the injection molding the materials, cavity number, and check the injection parameters, including maximum injection volume, injection pressure machine, the design principle of.2. check the locking force and the size of the mold mold related reference, analysis of the UG in the structure of injection mold based on the main channel, the runner, forming parts, optimize the guiding mechanism and the ejecting mechanism. The mold flow analysis software for plastic injection molding process simulation analysis, try to reduce the traditional mold assembly and debugging process, mold repair work, improve the mold production process, reduce the cost of production data analysis software. Results through the mold flow. To assess the feasibility of mould design.
