Description

Technical Field

[0001] The invention relates to the technical field of nano injection molding, and in particular to an automated production line for nano injection molding products. Background Art

[0002] Nano injection molding technology is a technology that directly achieves a firm bond between plastic and metal. This technology can replace the traditional metal-plastic integration technology using adhesives, eliminating the gluing process, shortening the production process, saving costs, and making the structure and appearance of the finished product more compact and reasonable.

[0003] With the development of the times, more and more advanced electronic products such as mobile communication devices and smart wearable devices use nano injection molding technology to integrate metal shells and metal structural parts (such as positioning columns, nuts, etc.). In order to obtain better injection molding effects, it is necessary to heat the metal shells and metal structural parts first, and then install the heated metal shells and metal structural parts into the injection mold.

[0004] At present, the heating and placement of metal shells and metal structural parts are usually performed manually using auxiliary tooling. First, the metal shell or metal structural part is manually moved to the heating equipment for heating using the auxiliary tooling, and then the heated metal shell or metal structural part is manually placed in the injection mold using the auxiliary tooling. Finally, the injection molding machine performs injection molding on the injection mold to obtain a molded product. Although this method can achieve nano injection molding, during the transportation or placement process, the metal shell or metal structural part is easy to move on the auxiliary tooling or fall off the auxiliary tooling, which seriously affects the work efficiency, and the manual feeding positioning is inaccurate, which seriously affects the quality and consistency of the product.
