A reasonable cooling system directly affects the speed of injection moulding time.With the help of the cooling analyzing function in Autodesk Moldflow,the hot areas of the product in the mould cavity were found out intuitively,and then the locations of the problem point were locked.A targeted solution was proposed to shorten the molding cycle.Based on the analysis re-sults and combined with 3D mould,targeted cooling strengthening was carried out on the hot ar-eas of the part to solve the bulging defects.
