Abstract

In this study, we used the commercial package (Unigraphics) to construct a junction box cable car when laser plastic parts have been processed using urethane resin(TSR-755) as a starting mold material. After construction, we carried out the filing, packing, cooling, and deforming analyzation using Injection Molding Analysis (Simpoe-Mold) to determine the gate positioning and automatic cooling cycle through the examination. The results show that inserting into the injection mold after processing ceramic has reduced the time of thermal conductivity of molding and cooling; and quick selection of gates and cooling lines could possibly cause an improvement of productivity.

본 연구에서는 우레탄레진(TSR-755)을 이용하여 레이저 조형으로 시작형 몰드를 가공하고, 상용패키지(Unigraphics)를 이용하여 자동차 단자함 케이블 케이스를 설계한 후 사출성형해석(Simpoe-Mold)을 사용하여 충전, 보압, 냉각, 변형해석을 수행하여 게이트 위치 선정 및 냉각 사이클 등을 검토 하였다. 해석결과, 세라믹소재 가공 후 사출금형에 인서트시켜 성형 시 열전도도 및 냉각시간을 줄여 줌을 확인할 수 있으며, 게이트 및 냉각라인 선정을 빠른 시간에 결정할 수 있어 생산성 향상을 가져올 것으로 나타났다.
