Progressive die with high corrosion resistance

Abstract

The invention discloses a progressive die with high corrosion resistance. The progressive die with the high corrosion resistance comprises an outer assembly, a die pressing assembly and a corrosion preventing assembly, wherein the corrosion preventing assembly comprises a brushing electroplating layer, a polyurethane layer and a wax antirust agent layer; the brush electroplating layer is arrangedon the outer sidewall of a quadrate convex die and is fixedly connected to the quadrate convex die; and the polyurethane layer is arranged at the outer part of the brushing electroplating layer and isfixedly connected to the brushing electroplating layer. According to the progressive die with the high corrosion resistance, the brushing electroplating layer is arranged on the outer sidewall of theconvex die and is capable of protecting the convex die during production as well as preventing acidic substances from invading the convex die; in addition, the polyurethane layer is arranged and is high in acid resistance and low in cost; the wax antirust agent layer is arranged and can form a dense semi-dry flexible protecting film on the surface, and unique water and air replacing components can be generated on the die surface due to the super permeability and adsorbability, thus the metal surface is prevented from corrosion, and as a result, the corrosion resistance and the rust resistanceof the die are achieved.

Description

technical field [0001] The invention belongs to the technical field of moulds, and in particular relates to a continuous mold with better corrosion resistance. Background technique [0002] Continuous die refers to the cold stamping die that uses strip-shaped stamping raw materials in one stamping stroke, and uses several different stations on a pair of molds to complete multiple stamping processes at the same time. Move once with a fixed distance until the product is completed. [0003] There are certain deficiencies in the original mold, because the surface of the injection mold will produce acid, acidic substances are corrosive, and it is very easy to rust on the surface, which may cause hidden dangers and affect the next production process in the continuous production of the mold. The next product link may affect the quality of intermediate semi-finished products. Contents of the invention [0004] The purpose of the present invention is to provide a continuous mold ...

Problems solved by technology

[0004] The purpose of the present invention is to provide a continuous mold with better corrosion resistance, to solve the existing certain deficiencies in the original mold proposed in the above-mentioned background technology, because the surface of the mold after injection molding will produce acidity, and the acidic substance is corrosive. It is very easy to rust on the surface, which may bring hidden dangers to the next production process in the continuous production using molds, affect the next product link or affect the quality of intermediate semi-finished products
