Study on Influence Law of Car Light Mask Warping Based on Moldflow
Aiming at the thin wall curved surface parts represented by the lamp mask,the injection molding process of the lamp face mask is analyzed by using Moldflow.The effects of gate location,die temperature and melt temperature on the warpage of plastic parts were studied.It is found that the filling quality of the plastic parts obtained by using the single side gate is good,and the uneven shrinkage is the main cause of warpage.When the melt temperature increases,it is helpful to reduce the warpage,and the different temperature of the cavity core is beneficial to reduce the warpage caused by uneven shrinkage.It is determined that the optimum forming temperature is 280℃,the temperature of the cavity is about 60℃,and the core temperature is about 70℃.
