Embodiment 1
[0047] A method for rapid processing of molds based on 3D printing mold cores, comprising the steps of:
[0048] S1: Choose No. 45 steel as the core material;
[0049] S2: The 3D printing technology chooses selective laser cladding (SLM), uses UG software to design the 3D drawing of the metal injection mold core, and then converts the successful STL format into the SLM forming equipment software for slicing;
[0050] S3: Select No. 45 steel as the substrate, fix it on the worktable, adjust the height of the substrate, and make the laser spot be on the surface of the substrate;
[0051] S4: Put the prepared metal powder into the hopper powder, evacuate the vacuum chamber, and then inject high-purity argon to protect the chamber;
[0052] S5: Turn on the red light switch of the laser, and adjust the optimal processing area through red light scanning. Raise the temperature of the substrate to 200°C;
[0053] S6: After the red light positioning is completed, turn off the red li...
