At present, when the injection molding part is produced by injection molding of an injection molding machine, workpieces such as screws, rivets and the like are required to be buried into corresponding positions in a cavity of the injection molding machine manually or through mechanical clamping jaws. Because the workpieces such as screws and rivets are small in size, the workpieces are not convenient to embed by manual operation or clamping and embedding by a mechanical arm, the workpieces are easy to shift or not thoroughly embed, and the quality of injection molding parts is further affected.
