The metal ring is integrally injection molded, so that the metal ring needs to be loaded into a mold core or a molding cavity and reliably positioned before each mold closing of the injection molding machine to prepare injection molding. However, the popular metal ring loading method is manual loading, but because the metal ring has a small volume and a high surface temperature of the mold core, the metal ring loading and positioning difficulty is high according to the special-shaped characteristics of the product, and the risk of scalding exists. In order to overcome the defects, existing injection molding manufacturers research and develop a plurality of application mechanisms which use mechanical arms to replace manual feeding, but most of the application mechanisms only aim at simplified feeding of workpieces in the same direction, and the existing mechanisms are still difficult to meet the requirements for automatic feeding in different directions and with different positioning accuracy.
