The cell phone front cover injection gate design not only decides the workpiece precision and the outer appearance,but also affects the convenience for the second time processing procedure.Analyzing this kind of tooling design,it was discovered that when the side gate,tab gate and tube gate were used,the cut gate was easy to have the defects,such as the injection gate handover and seriously deformation as well as the bad second time processing capabilities and so on.Through improving the gate mode,the similar tube gate was used,but the size was bigger,and the runner from lift entered the workpiece.When opened the tooling,lift moved and left an enough space for the gate to ensure the runner being connected with the workpiece together during the cooling process.The small gate trace outer appearance requirement was met.Moreover the cooling runner was able to assist the product positioning and fixing during the second time processing,which played the role of pouring gate and processing procedure..
