[0002] In the field of automated injection molding, sheet metal parts need to be taken out from a specific material feeder and placed into the mold cavity of an injection molding machine. In the existing material feeder for storing sheet metal parts, the sheet metal parts are often stacked together in a flat form. The stacking process is stacking one by one from bottom to top, which not only takes a long time, but also easily affects the quality of the sheet metal parts due to mutual squeezing. The placement and retrieval of sheet metal parts in the material feeder can only wait until one of the processes is completed before the next process can be carried out. In the meantime, the related mobile equipment will have a certain standby time, resulting in low overall feeding efficiency. Summary of the invention
