汽車頭燈用反射鏡的模具設計與分析

UP-MD＋GF在一般車燈業者以前都稱為BMC即Bulk Molding Compound（團狀模壓材料）的縮寫名稱。BMC材料通常成分有樹脂（如不飽和聚酯樹脂，環氧樹脂，酚醛樹脂等)，玻纖、填充料及各種添加劑。 UP-MD＋GF在工業上的應用非常廣泛，如醫療器材、水溝蓋、電子產品、電器用品及汽車工業等等。在車燈工業，UP-MD＋GF最常被拿來使用在大燈用反射鏡。本研究旨在分析UP-MD＋GF的成分特性，及其應用於於車燈反射鏡時，在射出成形的過程中因各種客觀的環境因素，藉由其模具的設計時，探討模具的成形肉厚分布、模具透氣結構的設計、模具加熱棒Watt的設定、模具Sensor溫度的分布、射出入料口的設計及射出機成型條件的設定，藉由CAE工具應用於RIM（Reactive Injection Molding）的製程來模擬不同的設計條件。以不同的模具設計條件，在試模成型後依配光所得到的數據，針對可進行設計變更的項目，評估對於產品包風及整體成型的影響性。在模流分析後，取得的各項數據，實際以配光結果來做最後驗證，藉以導入日後的模具設計標準。

UP-MD + GF there is another name for the BMC Bulk Molding Compound (dough molding material) the abbreviated name. BMC main component a resin (such as unsaturated polyester resin, epoxy resin, phenolic resin, etc.), glass fiber, fillers and various additives. UP-MD + GF in a wide range of industrial applications, such as medical equipment, drain cover,Electronic products, electrical appliances and automotive industry and so on. In the light industrial, UP-MD + GF most Been compared with the use of mirrors in the headlights. This study aims to analyze the UP-MD + GF component characteristics, and its application in the lamp reflector when the injection molding process due to various objective environmental factors, with its mold design, mold forming flesh explore distribution, breathable structure mold design, mold heating rods Watt setting, mold Sensor temperature distribution, injection into the discharge port design and injection molding machine conditions set by CAE tools used in RIM (Reactive InjectionMolding) manufacturing process. By simulation of the operation can be carried out for the project design changes, evaluate the product package and the overall shape of the wind resistance. In the mold flow analysis, the data obtained, the actual results to make the final verification light distribution, in order to import the future mold design standards.
