文档介绍：摘要本毕业设计说明书主要讲述对手机后盖进行模具设计的过程。通过对塑件的工艺分析,设计出塑料模具。本论文首先简单介绍了模具设计与分类,然后对产品材料性能作了介绍,并初步选择注射机。本说明书还详细叙述了模具结构方案,包括确定分型面、成型零部件的结构设计、斜顶内抽芯机构、脱模机构、合模导向机构、冷却系统等等的设计过程。还有重要零件的工艺参数的选择与计算。校核注射模与注射机的关系等。本设计主要是通过使用 CAXA 与AutoCAD 完成装配图、零件图。此次毕业设计综合了大学四年来所学的专业知识,从而进一步巩固了模具设计方面的相关知识,并积累了相关的设计意念与经验。 The graduation project on the brochures of the main mobile phone back for the die design process. The plastic parts of the process, the design of atwo-mode point of the plastic mold. First of all, this paper abrief introduction of the mold design and classification, and then the product was introduced by the material properties, and the initial choice of injection machine. This statement has also described in detail the structure of the program die, including the identification of sub-surface, forming the structural design of parts ponents, core-pulling mechanism within Xieding, Stripping agencies Die-oriented institutions, and so on the cooling system design process. There is still an important part of the process parameters of choice and calculation. Check with the injection mold injection machines, such as the relationship. This design is through the use of CAXA and pletion of the assembly, parts map. The integrated design of auniversity graduate in three years the school's expertise to further consolidate the mold design-related knowledge, and the accumulation of related design ideas and experience. 关键词: 侧抽芯塑料模具注射机 1 目录摘要第一章、塑件结构工艺分析与设计材料的选用脱模斜度加强肋塑件尺寸、公差与精度壁厚第二章、注射成型机的选择注射机的选用锁模力校核第三章、注射模的机构设计分型面的选择浇注系统设计主流道设计分流道设计浇口的设计成型零件结构设计排气系统设计第四章、侧抽芯机构的设计滑块内侧分型抽芯机构抽芯距计算第五章、工作尺寸计算计算公式 2 凹模的尺寸计算型芯的尺寸计算第六章、冷却系统的设计与计算第七章、模具闭合高度的确定结语致谢参考文献塑件的基本信息材料: ABS+PC 公差等级: IT2 批量:大批量生产 34 第1章塑件结构工艺分析与设计材料的选用该塑件为手机后壳,要求具有一定的强度、刚度、耐热和耐磨损等性能,同时还必须满足绝缘性。聚碳酸酯透明度较高,冲击韧性好,而且耐蠕变,使用温度范围广,尺寸稳定性好,电绝缘性优良,耐候性、无毒性。由于聚碳酸酯熔体粘度较高,在成型过程中极少发生泄漏现象。 ABS 合成塑料以其具有很好的韧性(抗震性) 、密封性,很高的机械强度,耐化学腐蚀,拿在手上很有质感的特点而受到人们的青睐。有优越的耐冲
