Treatment method for increasing die self-demouding performance

Abstract

The invention discloses a processing method for improving the mold unloading performance of a die, and the method comprises the following processes that: pretreatment is operated to the surface; proper alloy powder is chosen; the chosen alloy powder is pre-coated on a die forming surface; the die forming surface is irradiated by strong current pulsed electron beams to lead the alloy powder of the die forming surface to be melted under the radiation of electron-beam energy to obtain a surface mold unloading layer on the upper and the lower die forming surfaces; after being alloyed, the die is thermally treated. The processing method of improving the mold unloading performance of the die of the invention realizes the improvement of die self-mold unloading performance through the processing method, and replaces the original method of spraying and coating mold releasing agent on the die forming surface, thereby being in favor of eliminating the different degree pollution of the mold releasing agent to the product, the die and the environment, thereby the green manufacture can be realized. An alloying protective film, namely, a surface mold unloading layer on the die forming surface can decrease the attrition and the abrasion of the product to the die surface, and reduce the binding property of the product and the die material, thereby attaining the purpose for improving the die self-mold unloading performance.

Description

technical field [0001] The invention relates to the field of mold surface processing engineering, in particular to a treatment method for processing the mold surface to improve the mold self-release performance. Background technique [0002] Mold is an indispensable and important process equipment in industrial production. Automobiles and motorcycles rely heavily on molds. In order to reduce product costs, improve product quality and production efficiency, improve material utilization, and save energy, manufacturing industries around the world have widely used various mold forming processes to replace traditional cutting processes. Therefore, molds have developed rapidly and are widely used. application. [0003] The working conditions of the mold are becoming increasingly harsh. If the lubrication is poor, the forging or casting will come into contact with the mold. At this time, it is often difficult to demould the product due to sticking to the mold; It is easy to cause...
