Abstract

Taking a certain optical mold as the research object, addressing the issues of prolonged cooling time and warping deformation of the product due to uneven cooling that affects optical performance, a conformal cooling channel based on 3D printing technology was designed and simulated with Fluent fluid analysis software. By comparing the simulation results of traditional drilled channels, single-channel conformal channels, and multi-micro parallel conformal channels, it was found that the multi-micro parallel conformal channels can significantly improve the cooling efficiency of the injection molding process and reduce the temperature difference on the molding surface of the mold, where the molding cycle was shortened by 23.3%, and the temperature difference on the molding surface of the mold during the injection molding process was reduced to within 1.2℃.
