[0002] Metal powder forming refers to a series of processes that transform metal powder into solid metal parts. This process is usually divided into two major steps: powder forming and sintering. Among them, the most common metal powder forming technologies are powder metallurgy and metal injection molding.

[0003] During the injection molding process, the finished metal product is formed in the molding cavity of the mold. When demolding after molding, the finished product is often directly ejected by using the ejector structure in the mold. In this process, since there is a certain risk in reaching into the mold to take the material, the finished product often enters the collection frame by free falling after being separated from the mold. The placement after falling is relatively messy, and it needs to be rearranged during the subsequent sintering and degreasing processes. The operation is relatively troublesome. Therefore, it is necessary to design an auxiliary structure that can transport the finished product to a safe unloading position for neat unloading after molding, which is an important guarantee for improving the efficiency of subsequent processing.

[0019] The driving assembly includes a driving groove 23 and a servo motor 26. The driving groove 23 is opened in the cross bar 2.
