毕业设计-喷雾器喷头斜抽芯注射模设计，共31页，12908字，附设计图纸、任务书、文献综述等
摘要：本次毕业设计的题目是喷雾器喷头注塑模具设计。首先对所要设计的产品进行工艺的分析与计算，该塑件采用PVC为材料，然后在分析计算的基础上确定成型工艺方案，为一模4腔，推杆推出，点浇口，单分型面，浇口套内的主流道采用圆锥形，选用的模架为标准模架的A1型，导柱导套的安装用Z1的安装方式，再在此基础上进入模具总装配图的结构设计以及尺寸的确定。在此基础上对注塑模具的主要零部件尤其是成型零部件的尺寸进行设计与计算，期间要参考塑料成型相关的资料和翻阅各种塑料模具设计手册，并通过计算以确定模具的具体结构及尺寸以及成型零件的相关尺寸，通过不断的计算与修改，并在指导老师的悉心关怀和耐心指导下进行不间断的反复修改，最终独立完成这次毕业设计。在设计的过程中，主要成型零件采用镶拼结构，利于加工。

Abstract: The graduation project is the subject of spray nozzle injection mold design.First, the products are analysed and calculated as to the process of the design, with the products use PVC plastic parts as its material, and then the production process of a 4 cavity mold, putting launch point gate, single typeface, comprising the main gate with conical channel, selected as the standard mold of the A1-type mold, guide pins and bushings and installation methods with the Z1 installation is established, on the basis of the scientific calculation and analysis. On this basis, the structural design of the total assembly drawingand size is determined. Then, the main components of the injection mold molded parts, especially the size of the design should be calculated, during which processes, the relevant information and reading of all kinds of plastic mold design manual should be obtained, and the specific structure of the mold and size should be calculated and revised continually before determined. With the careful and patient guidance of instructor, as well as constant revise, ultimately an complete graduation project should be done independently. In the design process, the main use of mosaic structure of the molded part benefits processing.
