一模多腔的注塑模具结构设计及仿真分析
摘要
本次设计主要特点是根据MOLDFLOW软件仿真模流分析来指导模具结构的设计。MOLDFLOW软件模拟塑料熔体在整个注射过程中的充填、冷却及流动情况,确保获得高质量制件。打破传统模具结构设计的试模、修模等过程,达到降低成本,提高生产率的目的。在得到仿真分析最佳质量效果的数据、参数之后用来作为模具结构设计的依据。
本次设计主要包括:(1)模流仿真分析注射成型时熔体在型腔中的流动过程非常复杂,与许多因素如聚合物性能、制件结构、温度、压力、时间、模具结构及注射设备等有关。仿真定量地给出成型过程的成型窗口状态参数(如压力、温度、速度等)。(2)依据仿真的成型窗口状态参数进行整个注塑模具的结构设计。如注射机的选择、浇注系统、成型零件、合模机构、脱模机构和冷却系统的设计,绘制模具零件图和装配图等。

The Design of Multi-cavity Injection Mould For Multi-way Buttons and Simulation Analysis
ABSTRACT
The main features of the design is based on software simulation flow analysis MOLDFLOW to guide the design of die structure. MOLDFLOW software to simulate the injection of plastic melt in the process of filling, cooling and flow, ensuring access to high-quality parts. Breaking traditional mold structure design test mode, the process of repair molds, to reduce costs, improve productivity purposes. Obtained the best quality in the simulation results of the data, parameters after the design used as the basis for the mold.
The design includes: (1)Moldflow injection molding simulation of melt flow in the cavity is plex process with many factors. Such as polymer properties, parts structure, temperature, pressure, time, and injection mold structure and other related equipment. Quantitative simulation of the molding window molding process given the state parameters (such as pressure, temperature, speed, etc.). (2) Simulation based on the parameters of the molding window state the structural design of the injection mold. Such as the choice of injection machine, injection system, molded parts, mold bodies, stripping institutions and cooling system design, drawing die part and assembly drawings, etc..
