【正文】 共聚而成的聚合物，因此 ABS具有良好的成型性和綜合力學(xué)性能。 無(wú)定形料 其品種牌號(hào)很多，各品種的機(jī)電性能及成形特性也各有差異，應(yīng)按品種確定成形方法及成形條件。 本課題設(shè)計(jì)的要求 (1)產(chǎn)品為大批量生產(chǎn)，模具壽命為 50 萬(wàn)次，生產(chǎn)實(shí)現(xiàn)自動(dòng)化。這一階段，塑料的產(chǎn)量和品種不斷增加，成型加工技術(shù)更趨完善。迄今為止，除氟塑料外，幾乎所有的熱塑性塑料都可以采用此成型方法；它的特點(diǎn)是生產(chǎn)周期短、生產(chǎn)效率高、易自動(dòng)化，因此廣泛應(yīng)用于塑料制品的生產(chǎn) [1]。 本模具采用一模兩腔布局，通過(guò)對(duì)制件進(jìn)行 MPI 流動(dòng)分析后確定澆口為點(diǎn)澆口形式，綜合注塑容量、鎖模力、最大注塑面積和模內(nèi)壓力等技術(shù)參數(shù)確定注塑機(jī)型號(hào)為國(guó)產(chǎn)XSZY125 型臥式注射成型機(jī)。 關(guān)鍵詞 ： 注射模擬 三維造型 流動(dòng)分析 Abstract My graduate design is the injection simulation analysis and the design of the injection mold of the warmer’s coping. At first, this design acquires us to use Pro/E for the threedimensional modeling of the plastic workpiece. The next task is the injection simulation analysis of the workpiece by using Moldflow. Then we can determine every details of this design one after another. The mold cavity using a mold of two layouts of parts for MPI flow analysis for the spot side gate after the gate to determine the form of integrated injection molding capacity, clamping force, the largest injectionmold pressure area and the technical parameters, such as injection molding machine model to determine Horizontal injection molding XSZY125made. The characteristics of the mold are that slipper is in moving mold and cam finger is in setting template, which can ensure the corepulling acplished very well. This graduate design makes me master the professional knowledge more systematically.
