摘 要
本文主要研究的是应急灯外壳注塑模具的设计方法。本文首先介绍了选题的依据以及选这个课题的意义，并简单介绍了注塑模具的发展现状。然后分析了应急灯外壳制件的工艺特点，包括结构工艺性、成型特性与条件、材料性能等，并选定了成型设备。接着述说了应急灯外壳注塑模的分型面选择、模具基本结构及模架的选定及型腔数目的选定及布置，重点论述了成型零件、浇注系统、、脱模机构、合模导向机构以及冷却系统的设计。而后选定标准模架和模具材料，并校核注射机的相关工艺参数，如最大注射量、注塑压力等。最后阐述模具的工作原理，以及对安装运行过程中可能出现的问题予以总结、分析，并给于了对应的解决方法。
本文论述的应急灯外壳注塑模具采用两板式结构，采用一模两腔的型腔布置，最后通过推板将制件推出。在设计模具的时候，需用到SoliWorks软件进行模拟，以确定型芯型腔及浇口位。此次应急灯外壳注塑模具的设计各项参数必须来源可靠、选择准确、计算无误，其中最大注射量及注射压力是计算的关键。在工艺性上保证不影响操作的同时尽量做到了加工操作简单、方便。
本设计是在传统的应急灯上进行了创新，设计采用最领先技术LED显示，并把电池装在灯内部，外部也更美观。外壳的尺寸大小适中，模架也较好的选择，模具整体不大，采用整体安装。

Abstract
The designing methods of injection mould of the Emergency light shell are mainly introduced in this paper. This paper introduces the topic basis and the significance of choosing thistopic, and briefly introduces the development status of injection mold.And then analyzes the process characteristics of emergency lamp shellparts, including the structure, characteristics and conditions of moldingprocess, material properties, and select the molding equipment.Then tell the type emergency lamp shell injection mold, mold surfacestructure and mold base selection and the number of cavities selection andlayout, emphasis, gating system, forming parts, demoulding mechanism,clamping mechanism and the cooling system design.Finally the selected standard mold and mold material, and process parameters of injection machine check, such as the maximum injection volume, injection pressure etc.. The working principle of the die, as well as to the possible problems in the process of installation and operation are summarized, analysis, and give the corresponding solutions.
Shell of emergency lamp injection mold in this paper adopts two plate structure, the layout of the cavity of a mould with two cavities, the push platewill work out.In the design of mold, use the SoliWorks software to simulate, in order to determine the core and cavity and runner position.Must choose accurate, reliable, accurate calculation of design parameters of the emergency lamp shell injection mold, the largest injection quantityand injection pressure is the key.In the process that does not affect the operation at the same time as far as possible the process has the advantages of simple operation, convenient.
This design is the innovation in the emergency lights on the traditionaldesign, using the most advanced technology of LED display, and the battery installed in the light of internal, external and more beautiful.Moderate size of shell mold, is the better choice, overall not die, the wholeinstallation.
