基于pro/e的豆?jié){機杯體注塑模具的設計及凹模的加工仿真
摘要：注塑模具是塑料模具中使用最廣的廣泛的一種，能夠成型復雜的高精度的塑料制品。本課題是對塑料豆?jié){機杯體設計及其型腔仿真加工。
本模具考慮到年產(chǎn)量、工廠的設備及塑件的精度要求，選擇一模一腔結(jié)構(gòu)。
該豆?jié){機杯體較薄，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(tǒng)，在用以成型杯底的定模鑲件上，采用環(huán)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。
在設計過程中制定了合理的工藝方案，滿足了大批量生產(chǎn)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(chǎn)。通過合理的設計，本模具滿足生產(chǎn)與應用的要求。

Based on pro / e of the soya-bean milk machine cup body injection mold die design and simulation of machining
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.
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.
