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CAD／CAM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CAD／CAM 软件，如Pro／Engineer、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^论文统计表明，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，CAD／CAM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、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。

Plastic bucket mold cavity design and simulation processing
Abstract：At present ,injection molding is the plastics mould that has being used  most extensively , it can mold the complex and high accurate plastic product. The Subject is about the design of the plastic bucket process analysis.
 This mold considered the annual output, the factory equipment and models the accuracy requirement, chooses a mold cavity structure. The plastic bucket Tongbi thin, deep cavity, the core long, may be caused by mold, and the core of different thickness of thin plastic uneven, resulting in difficulties in forming, the high rejection rate. This is particularly important for the thin-walled plastic bucket. In light of these problems using a dynamic, scheduled to die-guided, guided sets of positioning. In the barrels are high partly based on an independent cooling system, for forming a barrel at the end of the module inserts, a circular cooling water, the flow of imports and exports in the design of the fixed-board. Core Cooling by the middle of a water main waterway, and then along the circumference are divided into six sub-cloth effluent water, so that the entire core is fully cooled, the whole mold of relatively uniform temperature field. Stripping plastic parts used in air to the top.
 Injection Mould CAD / CAM technology applications, to fundamentally change the traditional mold plastic product development and processing, greatly enhance the quality of the products and shorten the development cycle and reduce the cost of production, astrong impetus to the mold industry. Some large-scale commercialization of the CAD / CAM software, such as Pro / Engineer, Unigraphics II, Cimatron, MoldFlow, have been developed specifically for the injection mold design function modules for the mold design provides a very convenient tool. Statistics show that there are data, the use of CAD technology can shorten the time to die design 50 percent. Europe and the United States in some industrialized countries, CAD / CAM die industry has become a universal application of the technology. In CAD applications, has surpassed get rid drawing board, two-dimensional drawings of the initial stage. Die Design in the use of 3D CAD software enterprises have been close to 90 percent. At present, there are many domestic enterprises began to die of CAD software design. In the design process of formulating a reasonable programme to meet the requirements of mass production. At the same time, has also prepared a detailed document of the process to ensure the smooth processing and mould products production. Through rational design, production and application of molds to meet the requirements.
