Because the special manipulator for injection molding machine can greatly improve productivity and reduce production cost, it can stabilize and improve the quality of injection molding products and avoid losses caused by human error. Therefore, the manipulator of injection molding machine plays an increasingly important role in injection molding production. At present, the types of domestic manipulators are relatively single, and most of them are used to pick up parts. With the development of automation technology, the injection manipulator driven by full servo motor can realize other functions besides picking up parts, such as in-mold labeling, in-mold inlaying, packing, goods stacking and so on. Perhaps in the future, there will be more robots used in various processes, such as feeding, mixing, automatic loading and unloading of molds, waste recycling and so on. And they will develop in the direction of intelligence.
