1、.塑料提桶模具设计及其型腔仿真加工摘要：注塑模具是现在所有塑料模具中使用最广的模具，能够成型复杂的高精度的塑料制品。本课题是对塑料提桶模具设计及其型腔仿真加工。本模具考虑到年产量、工厂的设备及塑件的精度要求，选择一模一腔结构。该塑料桶桶壁较薄，腔深、型芯长，可能会造成因型腔、型芯不同而造成塑料壁厚薄不均，从而造成成型困难，废品率高。这一点对于薄壁通体尤为重要。针对这些问题采用了型芯和型腔以导柱、导套定位。在桶身高度部分采用了独立冷却系统，在用以成型桶底的定模镶件上，采用环形水道冷却，水流的进出口设计在定模固定板上。型芯冷却采用中间一主水道进水，然后沿圆周均布分成六个分水道出水，从而使型芯各处得
2、到充分冷却，整个模具的温度场比较均匀。塑件脱模时采用气动顶出。注塑模具CADCAM技术的应用，从根本上改变了传统的塑料产品开发和模具加工方式，大大地提高了产品的质量、缩短了开发周期、降低了生产成本、强有力地推动了模具工业的发展。一些大型的商品化CADCAM 软件，如ProEngineer、Unigraphics II、Cimatron、MoldFlow等，都已开发出专门用于注塑模具设计的功能模块，为模具设计提供了十分方便的工具。有资料统计表明，采用CAD技术可以使模具设计时间缩短50。在欧美一些工业发达的国家，CADCAM已经成为模具行业一种普遍应用的技术。在CAD应用方面，已经超越了甩掉图板
3、、二维绘图的初级阶段。在模具设计中采用三维CAD软件的企业已经接近90。目前，国内也有不少企业开始应用CAD软件进行模具设计。在设计过程中制定了合理的工艺方案，满足了大批量生产要求。同时，还编制了详细的工艺文件来保证模具的顺利加工及制品的生产。通过合理的设计，本模具满足生产与应用的要求。关键词：注塑模具；加工工艺分析；Pro/E；本设计来自：完美毕业设计网http:/登陆网站联系客服远程截图或者远程控观看完整全套论文图纸设计客服QQ：8191040Plastic bucket mold cavity design and simulation processingAbstract：At pre
