Abstract

The invention discloses a high-strength high-abrasion-resistance mold. The high-strength high-abrasion-resistance mold comprises a mold steel substrate material and a protection film, wherein the surface of the mold steel substrate material is coated with the protection film, and the mold steel substrate material is a hot-work mold steel substrate material. The protection film is prepared from, by mass, 40%-45% of polyurethane resin, 30%-35% of PET resin, 8%-10% of graphite powder, 3%-4% of titanium dioxide, 3%-5% of boron chloride, 3%-5% of silicon carbide and 4%-5% of aluminum oxide. According to the mode, the high-strength high-abrasion-resistance mold has the higher heat intensity, has the quite-good abrasion resistance in the high-temperature condition, and can conform to various bad conditions in the mold production process.

Description

technical field [0001] The invention relates to the field of molds, in particular to a mold with high strength and high wear resistance. Background technique [0002] The steel required for the mold can be divided into three categories: cold work die steel, hot work die steel and plastic mold steel. Cold dies are used for forging, stamping, cutting, die-casting, etc. Cold working dies include cold stamping dies, wire drawing dies, drawing dies, embossing dies, thread rolling dies, thread rolling plates, cold heading dies and cold extrusion dies, etc.; Hot working dies are divided into several main types of hammer forging, die forging, extrusion and die casting, including hot forging dies, press forging dies, stamping dies, hot extrusion dies and metal die-casting dies; plastic dies include thermoplastic dies and Thermosetting plastic molds, steel for plastic molds are required to have certain properties such as strength, hardness, wear resistance, thermal stability and corr...
