台灯外壳注塑模具设计（全套图纸）.docVIP

摘 要 本次毕业设计的课题为台灯外壳的注射成型模具设计，主要从台灯外壳材料特性、成型性能及台灯外壳的形状、型腔结构等多角度详细分析了台灯外壳注塑加工工艺性。因无批量生产要求，且零件体积不大、结构较为简单，故采用“一模四件”的生产方式。初步选择注塑机的型号和规格，分析台灯外壳结构及生产方式宜采用单分型结构，对浇注系统、成型零部件、导向及定位机构、脱模机构、冷却系统、模架各部件零件都进行了相关的计算和选择。最后，在参照台灯外壳的体积、重量等参数后对注塑机的相关主要参数进行校核，以判断所选的注塑机能否满足注塑要求。 关键词：注射成型；一模四件；单分型面；注塑机； Abstract The graduation design subject to cover the injection molding design, mainly from the plastic material characteristics, forming performance and plastic parts, die-cavity structure is analyzed in detail from multiple perspectives, such as plastic injection molding process technology. Because there is no batch production requirements, and small parts, simple structure, a mold piece of the means of production. Preliminary selection of type and specification, injection molded parts structure analysis and production mode, appropriate USES double type structure, gating system, forming parts, orientation and positioning and demoulding mechanism, cooling system, formwork components parts are made of calculation and choice. Finally, in the reference of the volume, weight after injection parameters such as the main parameters related to test to determine whether meet the selected injection molding requirements.
