摘要：注塑模具是現在所有塑料模具中使用最廣的模具，能夠成型復雜的高精度的塑料制品。本課題是對塑料提桶模具設計及其型腔仿真加工。
 本模具考慮到年產量、工廠的設備及塑件的精度要求，選擇一模一腔結構。
該塑料桶桶壁較薄，腔深、型芯長，可能會造成因型腔、型芯不同而造成塑料壁厚薄不均，從而造成成型困難，廢品率高。這一點對于薄壁通體尤為重要。針對這些問題采用了型芯和型腔以導柱、導套定位。在桶身高度部分采用了獨立冷卻系統，在用以成型桶底的定模鑲件上，采用環形水道冷卻，水流的進出口設計在定模固定板上。型芯冷卻采用中間一主水道進水，然后沿圓周均布分成六個分水道出水，從而使型芯各處得到充分冷卻，整個模具的溫度場比較均勻。塑件脫模時采用氣動頂出。
 注塑模具CAD／CAM技術的應用，從根本上改變了傳統的塑料產品開發和模具加工方式，大大地提高了產品的質量、縮短了開發周期、降低了生產成本、強有力地推動了模具工業的發展。一些大型的商品化CAD／CAM 軟件，如Pro／Engineer、Unigraphics II、Cimatron、MoldFlow等，都已開發出專門用于注塑模具設計的功能模塊，為模具設計提供了十分方便的工具。有資料統計表明，采用CAD技術可以使模具設計時間縮短50％。在歐美一些工業發達的國家，CAD／CAM已經成為模具行業一種普遍應用的技術。在CAD應用方面，已經超越了甩掉圖板、二維繪圖的初級階段。在模具設計中采用三維CAD軟件的企業已經接近90％。目前，國內也有不少企業開始應用CAD軟件進行模具設計。在設計過程中制定了合理的工藝方案，滿足了大批量生產要求。同時，還編制了詳細的工藝文件來保證模具的順利加工及制品的生產。通過合理的設計，本模具滿足生產與應用的要求。

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.
