设计简介
M610牌电热水壶底座的注塑模具设计
摘 要
水壶底座的形状虽然较为简单，且体积较小，但在模具设计中要考虑的因素有很多，除考虑它的出模、分型面，还需要考虑他成型的质量等。这些问题又和排气结构和冷却系统等有关。另外还要考虑它的制造难度和成本，所以此设计应认真分析塑料制品的结构，寻求最佳的设计方案。本设计首先从水壶底座结构进行工艺分析，主要对产品结构的分析，以及材料的分析，从而确定模具结构特点及总体方案，然后再对注射模结构进行设计，其中包括浇注系统的设计，型腔结构设计，型芯结构设计及模架的选择等，最后是对有关参数的校核，里面包括注塑机型号的选取，型芯、型腔尺寸计算，选择出此设计需要的参数，当然设计还要考虑它的经济性，因此在此设计最后对本设计的经济性进行了进一步的分析。

Abstract
Although the shape of the wind blower relatively simple and low- smaller, but factor in the mold design has a lot to consider , in addition to considering it a mold parting surface , you also need to consider the quality of his molding and so on. These problems are structural and cooling and exhaust systems and so on. Also consider the difficulty and cost of its manufacture , so this should be carefully designed to analyze the structure of plastic products, finding the best design. First, the design process analysis from a hair dryer rear structure, mainly on product structure analysis, and materials analysis to determine the structural characteristics of the mold and the overall program , and then the structure of the injection mold design , including design of gating system , type cavity design, structural design and the mold core frame selection , and finally check the relevant parameters, which includes the selection of the injection molding machine model , core, cavity size calculation , select the parameters needed for this design , of course, design should also consider its economy , so the design of the final design of the economy were further analyzed .
