Structural Analysis Examining the Mold Deformation Behavior for the Detection of the Flash in the Injection Mold

Abstract
Flash known as burr is defined as additional resin filling a gap between parted surfaces. It is caused by mold deformation from excessive cavity pressure. In our previous research, there had been attempts to detect the occurrence of the flash using the contact-pressure-sensor which was developed. Although the sensor showed a reliable response of mold deformation, the sensor alone could not tell us the exact occurrence of flash. In order to understand response of the sensor, a structural analysis in conjunction with a molding analysis was carried out. In the analysis, the platens of an injection molding machine were included in the model to accurately implement deformation of the mold. We found that the trend of strain predicted by the CAE analysis was similar to the measured one although the strain value was not comparable. We examined the stress at the parting edge and found that the most probable moment for the flash occurrence appeared when the z-axis stress was closed to zero value.
