有柄盖注塑模具设计毕业设计说明书VIP免费

AbstractThis design needing the thickness of plastic uniform, the surface should be smooth .Considering the size of product is large, so the design uses one-mode and one-cavity form in this case. The design also use half-structure to forming the handle of product after analyzing the structure of the product. In order to ensuring the surface smooth, the edge without distortion, we use pneumatic ejection structure. This structure also simplifies the mold structure, economical and practical. Meanwhile, we measured the connection between product quality and the cost. Making the mold of simple structure 、 low processing costs of production 、 easy processing and usability as much as possible.Key wordsMug; Injection Mould; Half-structure; Pneumatic ejection structure目 录摘要、关键词........................................................IAbstract、Key words.......................................................II目录.......................................................................III1.引言.......................................................................12.塑料工艺分析与模具方案确定..............................................22.1 制件的分析..............................................................22.2 模具方案的初步确定....................................................32.3 总装图...................................................................33. 塑料的成型特性及工艺参数...............................................44. 注塑设备的选择..........................................................44.1 计算塑件的体积和重量..................................................44.2 选择设备型号、规格、确定型腔数.......................................45. 浇注系统.................................................................55.1 确定成型位置...........................................................55.2 分型面的选择.......................
