3 Manufacturing method of hot stamping parts for local multifunctional materials by using three-dimensional lamination technology

摘要

A method for manufacturing a mold for manufacturing a local multi-physical hot stamping part using a three-dimensional additive manufacturing technology according to the present invention includes the steps of designating a high-strength portion and a low-strength portion of the hot stamping product; Manufacturing a mold body; Manufacturing a hot stamping cooling block that can be combined on the mold body; And assembling the cooling block to the mold body and then processing the surface shape through mechanical processing to finally complete the mold; including, a product shape using metal lamination processing technology on the high-strength part on the hot stamping cooling block. It is characterized by forming the same cooling channel as.
