Abstract

Abstract: A 3D model for window interior decoration was analyzed to determine the position of hot runner gate by the NX12.0 software, and the die surface temperature, melt temperature, ejection temperature and cooling time were selected as research objects. The mold surface temperature was determined as 60 ℃, the melt temperature as 260 ℃, the ejection temperature as 82 ℃, and the cooling time was determined as 30 s by means of the orthogonal test and extreme difference analysis method. A minimal warping rate of 1.45 % was achieved for the window interior trim. The group parameters of K3H3J2I3 were tested and verified. The test results indicated that the appearance quality of the window interior trim was fine, and there was no warpage phenomenon observed. This proved the accuracy of Moldflow 2018 finite element analysis data and the rationality of extreme difference analysis method.

Key words: mold surface temperature, melt temperature;ejection temperature;cooling time;orthogo-nal test
