塑件三维外侧
摘要
当前汽车车灯接线盒注塑成型工艺方法很多，为了进一步提高生产效率，节约生产成本，本文在现有的注塑成型工艺冷却方面做了进一步改进，选择在型芯上开设冷却水道，希望缩短冷却过程，从而提高生产效率。
本文主要介绍了经过优化型芯冷却系统后的汽车车灯接线盒注塑模设计、塑料成形工艺以及注塑的过程，也对注塑机也进行了一些简单的介绍。主要设计过程有：塑料制品的工艺分析，型腔数目的确定，型芯冷却系统的设计，注塑机的选择以及模具的结构设计。本文设计的是一模四腔两板式模具，由于汽车车灯接线盒的特殊形状，可以直接脱模，本文对模具的各部分零件进行了设计与计算。在完成了一系列计算和构想之后，利用三维软件画出注件的三维图，并设计好浇注系统、开模方向，然后进行开模仿真，在确定无误之后，利用EMX7.0设计模架，在完成模架设计之后，利用装配方法把整套模具完成整体设计并导出总装配图。
通过采用组合式型芯，并在型芯块上设计螺旋状冷却水道的冷却系统措施后，注塑过程中注件得到了良好的散热，提高了注件生产效率。在现有的工艺上做了改善之后，汽车车灯接线盒的注塑过程大大缩短，既提高了生产效率，同时也节约了生产成本。

Abstract
In order to improve the production efficiency and save the production cost, the current injection molding process of automobile lamp junction box is improved. The coolingwater channel is set up on the core, so the cooling process can be shortened so as to improve the production efficiency.
This paper mainly introduces the injection mold design, plastic forming process and injection molding process of automobile lamp junction box after the optimized core cooling system, and also introduces some simple introduction to the injection molding machine. The main design processes are: the process analysis of plastic products, the determination of the number of the cavity, the design of the core cooling system, the selection of the injection molding machine and the structure design of the mould. This design is the first mock exam four cavity two plate mold, due to the special shape of automobile lampwiring box, can directly release, the mold parts of the design and calculation. After a series of calculations and ideas have been completed, three-dimensional software is used to draw the 3D drawings of the injection parts, and the casting system and the direction of the die are designed, then the model simulation is carried out. After the error is determined, EMX7.0 is used to design the mold frame. After the design of the mold is completed, thewhole set of moulds is designed and guided to complete thewhole design and guide. A general assembly drawing.
After the combined core is adopted and the cooling system of the spiral coolingwater channel is designed on the core block, good heat dissipation is obtained in the injection process, and the production efficiency of the injection parts is improved. After improving the existing technology, the injection process of the car lamp junction box is greatly shortened,which not only improves the production efficiency, but also saves the production cost.
