1、洗发水瓶盖注塑模具设计摘 要:本次模具设计的内容是“洗发水瓶盖注塑模具设计”。这个制品的结构近似一个壳体,主盖与其上面的小盖以铰链相连,打开后,小盖固定在一特定位置,合上后与主盖成一整体。设计内容是从零件的工艺分析开始的,根据工艺要求来确定设计的大体思路。设计开始是零件的材料选择,接下来是成型参数、密度、收缩率的确定,模具种类与模具设计的关系、塑件的尺寸精度与结构、分型面位置以及型腔数量和排列方式确定、注射机的选定及注塑机参数的校核、模具成型零件的设计、模架的选择、模具结构设计(浇注系统、导向机构、脱模推出机构)、冷却系统的设计计算、注射模标准件的选用及总装技术要求,最后通过查阅相关的注塑模具
2、图册,设计出合理的模具装配图及主要零部件图。其中模具结构设计是这次设计的主要内容,进一步进行模具总装图及零件的设计,总结出并熟练掌握注塑模具设计的规律和方法。通过本次设计不仅让我熟悉了课本所学的知识,而且让我做到所学的运用到实践当中,更让我了解了塑料模具设计的全过程和加工实践的各种要点,使我在实践设计中有一个质的飞跃。关键词:洗发水瓶盖,注塑模,聚丙烯(PP),浇注系统Shampoo bottle injection mold designAbstract :The contents of the mold design is shampoo bottle injection mold des
3、ign. The structure of this product is approximately one case, the main cover their little above the hinge cover is connected, open, small cap fixed at a specific location, and after closing the main cover as a whole. Design is a process of analyzing the part from the beginning, according to the tech
4、nical requirements to determine an approximate idea of the design. Design began as part of the selection of materials, Next is to determine the molding parameters, density, shrinkage, mold and die design types of relationships, dimensional accuracy and structure, as well as the cavity parting surfac
5、e location number and arrangement of plastic parts identified, selected and injection machine injection molding machine checking parameters, molding parts of the design, choice of mold, mold design (gating system, guiding mechanism, stripping launch mechanism), the calculation of the cooling system
6、design, injection mold standard parts selection and assembly technology requirements, Finally, access to relevant atlas injection mold, the mold assembly design a reasonable figure and main parts diagram.The main content of which is the design of the mold structure design. Further mold assembly draw
7、ing and parts design, summed and master the laws and methods of injection mold design. Through this design is not only familiar with the knowledge I learned in textbooks, but I do use what they have learned into practice, made me understand the whole process and the various elements of the plastic m
