Abstract

The invention relates to the field of H13 steel mold manufacturing, in particular to a method for selective laser melting manufacturing of an H13 steel mold with a conformal cooling system. The methodcomprises the following steps: S1, constructing a three-dimensional model according to the shape of the to-be-processed H13 steel mold with the conformal cooling system, and saving the three-dimensional model as an STL file; S2, importing the STL file into slicing software for slicing treatment; S3, acquiring a laser scanning path according a slicing treatment file, and importing data of the laser scanning path into selective laser melting equipment; S4, setting the selective laser melting equipment; S5, carrying out selective laser melting manufacturing; S6, cooling the formed mold in a forming bin to the room temperature; S7, taking out the cooled mold and a substrate, and subjecting the mold and the substrate to vacuum treatment together; and S8, separating the mold and the substrate.By adoption of the method, the problems that in the prior art, a conventional mold processing method is low in processing efficiency and long in cycle, and a mold structure with a complex cooling system cannot be processed are solved.

Description

technical field [0001] The invention relates to the manufacturing field of H13 steel molds, in particular to a method for manufacturing H13 steel molds with a conformal cooling system by selective laser melting. Background technique [0002] Mold is an extremely important industrial equipment in modern manufacturing industry. It is a tool that uses external force to form a blank and make it into a workpiece with a specific shape and size. At present, the mold industry has become an important symbol to measure the level of a country's manufacturing industry. It is mainly used for mass production of related components and parts in industrial products, and the level of the mold industry is directly reflected in the quality and life of the mold. The factors that affect the life of the mold mainly include structural design, forming and manufacturing process, selection of mold material, production operation and maintenance. [0003] At present, the manufacturing and processing o...
