Plastic injection mold design of quilting machine clipbased on Moldflow analysis
In this paper,the short plate of quilting machine clamp is taken as an example,and the reasonable gate position and gate form of plastic parts are determined based on Moldflow finite element analysis software.The filling time,injection pressure and clamping force of the plastic parts are accurately predicted.The simulation results also predict the volume shrinkage rate of plastic parts and the defects such as fuse weld lines and cavitation.The simulation results provide a reliable basis for the selection of injection molding equipment and the setting of molding process parameters,and provide a direction for the optimization design of mold.Based on the above analysis results,a set of injection mold with two cavities and side gate,side parting with inclined guide pillar and core pulling mechanism was designed and successfully tested at one time.The application of Moldflow analysis software in the design of plastic mold can not only effectively reduce the cost and cycle of mold design,but also provide a reliable reference for the optimization design of mold for similar parts.
