Research on design and application of conformal cooling die based on metal 3D printing technology
The 3D printing technology was used to manufacture the conformal cooling die,and the 3D printing substrate was studied.The maximum compressive strength and compressive yield strength of the 3D printing composite added with 30％(mass fraction)WC reached 1 757 MPa and 1 677 MPa respectively,which was about 20％higher than that of the die steel matrix.In view of the problems of long cooling time,product warping deformation and size instability in die design,a conformal cooling water path die based on Metal 3D printing is designed,and the simulation analysis is carried out with the help of Moldflow software.The results show that the conformal water path scheme can significantly improve the cooling efficiency and reduce product deformation.Metal 3D printing technology has a wide application value in the field of conformal cooling die.
