Technical Field

The invention relates to the technical field of shoe molds, in particular to application of silver electroplating paint on a shoe mold and a construction process thereof.

Background

The sole forming mold is called a shoe mold for short, and is a forming mold for manufacturing soles. At present, the preparation method of the shoe mold mainly comprises a casting process and a metal 3D printing method. However, no matter which method is adopted to prepare the obtained shoe mold, the outer surface of the non-forming inner cavity of the shoe mold needs to be treated, so that the aesthetic property of the outer surface of the shoe mold is improved, and more importantly, the heat resistance and the corrosion resistance of the shoe mold are improved, so that the service life of the shoe mold is prolonged, and the like.

At present, the traditional shoe mold outer surface treatment method usually adopts an electroplating process, namely, a metal coating is plated on the outer surface of the shoe mold, however, the electroplating process has larger metal pollution. In the current society advocating environmental protection, a plurality of electroplating enterprises are eliminated, so that the current electroplating industry approaches to a monopoly state, and the electroplating treatment cost of the outer surface of the shoe mold is greatly increased. In addition, the time consumption of the plating process is long, and the plating area of the outer surface of the shoe mold is difficult to be accurately controlled. Therefore, we provide a new shoe mold outer surface treatment method and its process method.
