Anti-corrosion and anti-abrasion die and preparation method thereof

Abstract

The invention relates to the technical field of die manufacturing and particularly relates to an anti-corrosion and anti-abrasion die and a preparation method thereof. The anti-corrosion and anti-abrasion die is prepared from the following raw materials according to the weight proportion: 20 to 26 parts of a ceramic powder, 12 to 16 parts of titanium nitride, 9 to 14 parts of a graphite powder, 5to 9 parts of an aluminium powder, 4 to 7 parts of a beryllium powder, 3 to 8 parts of a copper powder, 8 to 11 parts of nanometer titanium dioxide, 6 to 10 parts of an iron powder, 14 to 18 parts ofdiatomite, 6 to 11 parts of carbon fiber, 2 to 5 parts of a defoamer and 3 to 7 parts of a curing agent. According to the anti-corrosion and anti-abrasion die and the preparation method thereof, the nanometer titanium dioxide, the diatomite, the carbon fiber and the copper powder are selected as raw materials for preparing the die, wherein the nanometer titanium dioxide, the diatomite and the carbon fiber are matched with one another, so that the prepared die has enhanced antibacterial capability and improved corrosion resistance, and further the beryllium powder and the copper powder form analloy under high temperature, so that the anti-abrasion performance of the die is improved; the service life of the die is remarkably prolonged and the cast intensity is remarkably enhanced; moreover,the defects of molten metal cinder adhesion and corrosion to the die can be overcome, cast surface quality is improved, and the production cost is lowered.

Description

technical field [0001] The invention relates to the technical field of mold manufacturing, in particular to an anti-corrosion and wear-resistant mold and a preparation method thereof. Background technique [0002] Mold, various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products. In short, a mold is a tool used to make shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. Known as the "Mother of Industry". [0003] Under the action of external force, the blank becomes a tool with a specific shape and size. Widely used in blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, and compression molding or injecti...
