模具设计中英文内容摘要和关键字

摘要

注射成型是热塑性塑料成型的主要方法之一，可以一次成型形状复杂的精密塑件。注射机在今天是普遍的，但在注射机上安装的模具有各种各样的，这些模具由于塑料制品的不同而各异，到底安装哪一种受到特定的尺寸限制，因而注射模具的设计随着塑料制品的不同而改变。注射模具的主要过程是将熔融料模塑成型为最终塑料制品的形状。这个过程是充满型腔的过程，型腔系统包括型芯，型腔，嵌件。型腔系统几何形状和尺寸直接由塑料模塑制品决定，因此，型腔系统的所有组成部分被称为依赖产品部分。塑料业的快速发展要求各种日常用品外壳快速更新。本设计进行了一款医用卷绑板注射成型模具设计，对零件结构进行了工艺分析。确定了分型面、浇注系统等，选择了注射机，计算了成型零部件的尺寸。采用潜伏式浇口。利用直导柱导向，型芯整体推料与推杆顶料相配合,在二次顶出机构的动作支持下完成脱模。并对模具的材料进行了选择。如此设计出的各种结构可确保模具正常工作时安全可靠。最后对模具结构与注射机的匹配进行了校核。并用UG/AutoCAD绘制了一套模具装配图和零件图。

ABSTRACT

Injection molding is one of the main molding methods for thermo plastics, and it can once-formed delicate plastic members with sophisticated shape.Inject the machine to is widespread on today, but at molding tool that inject on board gearing contain every kind of each kind of, these molding tools because the plastics product different but each , go down to bedrock the gearing a design for suffering particular size limitting, as a result injecting molding tool to product different along with the plastics but change.Because setting up the mold differently several why method, the different molding tool construction usually also is inevitable.Main process that inject the molding tool is to anticipates the meltdown to mold to model for end the shape that plastics product.This process is the process of the alive with type , the type system includes the type , type , the piece of .The type system is several why the shape is direct to be producted by plastics mold with the size decision, therefore, the havings of the type system constitutes the part is called counting on product part. The rapid development of mobile phone industry requires that the shell be renewed quickly. This paper discussed the design of plastic injection mould of the upper cover of the mobilephone

flip-open covers., and the process analysis of the parts' structures.。The author determined the parting surfaces and the gating system etc, choosed the injection molding machine，calculated the sizes of the molding parts. Side gate and hydraulic inner action was used, straight pillar and puncher was used for guiding and conveying the materials. The author also choosed the materials of the mould. The structure designed in such way can ensure the reliable running of the mould. Finally, the author checked the match between the mould structure and the injection molding machine. And the author also drew a set of mold assembling chart and parts chart using autoCAD software.
