Forming method of maraging steel mold adopting selective laser melting

Abstract

The invention discloses a forming method of a maraging steel mold adopting selective laser melting. A three-dimensional structure of the mold is designed firstly by using three-dimensional design software such as Solidworks, ProE and Ug; and then the three-dimensional mold is subjected to slicing layering and route planning treatment, data are guided into a selective laser melting device, reasonable technical parameters are set, and the mold with a complex cooling channel is formed at a time. The mold formed by the method has the advantages of being high in compactness, few in internal defect, high in forming efficiency and high in free degree on the follow-up forming cooling channel. According to the forming method of the maraging steel mold adopting selective laser melting, the production period of the mold is effectively shortened, forming efficiency is high, external disturbance is small, the compressive property and production efficiency of the mold are remarkably improved, and meanwhile manufacturing cost is greatly reduced. After the directly-formed mold is subjected to solution and aging treatment, hardness and strength of the mold are remarkably improved, and the using requirements of the mold are met.

Description

technical field [0001] The invention relates to a preparation process of a maraging steel mold, in particular to a method for forming a maraging steel mold by laser selective melting. Background technique [0002] A mold is a tool used to shape 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 by changing the physical state of the formed material. It is used under the action of external force in blanking, forming stamping, die forging, cold heading, extrusion, pressing of powder metallurgy parts, die casting, and compression molding or injection molding of engineering plastics, rubber, ceramics and other products. Blanks become tools for workpieces of specific shape and size.

Problems solved by technology

[0003] The mold not only needs to have high hardness and strength to ensure its service life, but also because a lot of heat is generated during the use of the mold, the heat must be conducted in a certain way to cool the mold, which is generally realized by designing cooling channels, and The traditional mold manufacturing methods are forging, casting, etc., limited by the manufacturing process, it is impossible to obtain the ideal high-efficiency cooling channel, and the simple cooling channel manufactured cannot conduct the heat generated by the mold in time, thereby reducing the service life of the mold; and By reducing the frequency of mold use, the production efficiency is reduced, which is not conducive to the normal development of the enterprise
