水杯蓋模具設(shè)計(jì)及型腔仿真加工
摘要:注塑模具是現(xiàn)在所有塑料模具中使用最廣的模具,能夠成型復(fù)雜的高精度的塑料制品。本課題是對(duì)水杯蓋模具設(shè)計(jì)并分析加工工藝。
本模具考慮到年產(chǎn)量、工廠的設(shè)備及塑件的精度要求,選擇一模一腔結(jié)構(gòu)。以水杯蓋主體和防偽圈之間的面作為分型面,使制品強(qiáng)制脫模。流道采用帶環(huán)形冷料穴,脫模時(shí)方便將主流道凝料和塑件帶出,確保熔融塑料幾乎能同時(shí)到達(dá)型腔的進(jìn)料口。為了使動(dòng)、定模能夠準(zhǔn)確地動(dòng)作, 導(dǎo)向定位機(jī)構(gòu)利用導(dǎo)柱與導(dǎo)套的配合。頂出機(jī)構(gòu)是推桿推出的一次脫出機(jī)構(gòu)??紤]到零件的位置關(guān)系,冷卻水道采用循環(huán)式分布,以便冷卻均勻、快速。
采用Pro/E來(lái)實(shí)現(xiàn)塑料瓶蓋三維設(shè)計(jì)及模具成型零件設(shè)計(jì),分析制件的成型質(zhì)量和完成分型面的設(shè)計(jì),再采用CIMATRION來(lái)實(shí)現(xiàn)其數(shù)控仿真的加工,并在產(chǎn)品設(shè)計(jì)及模具裝配過(guò)程中,輔助以必要的理論計(jì)算,將數(shù)字化設(shè)計(jì)與理論計(jì)算結(jié)合起來(lái),可以大大縮短產(chǎn)品研發(fā)周期、模具設(shè)計(jì)周期,提高產(chǎn)品設(shè)計(jì)及模具設(shè)計(jì)的準(zhǔn)確性、產(chǎn)品成型質(zhì)量,降低產(chǎn)品研發(fā)、模具設(shè)計(jì)成本。在設(shè)計(jì)過(guò)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(shí),還編制了詳細(xì)的工藝文件來(lái)保證模具的順利加工及制品的生產(chǎn)。

The Design and Simulation
Processing of Mold for Watercup’s
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 caps and simulation processing.
Considering the annual output, the equipment of the factory and the requirement of precision of the plastic product,one cavities in a mould. The middle horizontal surface of the goods was to cap the main circle and security between the surface as a type face, so that mandatory Stripping products. The runner is designed to be balanced and symmetrical distribution, ensure that melting plastic could reach each cavity’s gate almost.. Suspension and Positioning mechanism use matched guide pillar and guide sleeve to make movable mould, fixed mould to work accurately. The knockouts uses once ejecting mechanism that lifter pushes out. By the relation of the position of each part, cooling channels are designed to straight channels to cool effectively, quickly.
With Pro/Engineer,MoldFlow to implement three-dimensional design and mold volume design of the Plastic caps, and shaping quality of part was analyzed and the parting line was designed by Pro/Engineer, then utilized CIMATRION to accomplish the assemblage of the mold with the assistance of essential theory calculate mixed with figure design. It would not only shorten the cycle of product research and mold design, and improve the preciseness and the product shaping quality, but also lower the cost of the research. Having made the rational craft scheme in the design process ,so it has met the requirement of producing in enormous quantities. Moreover, it also prepared a detailed document to ensure that the process for the smooth processing of mold and apparel production.
