3 Method to manufacture cooling block for hot stamping metallic pattern using three dimensional metal-print

摘要

The present invention relates to a method of manufacturing a cooling block for a hot stamping die using a three-dimensional metal printer, and more particularly, to a method of manufacturing a cooling block for a hot stamping mold, And forming an upper block so as to form a channel by using a three-dimensional metal printer on upper portions of the plurality of semicircular channels formed in the lower block. The cooling method for a hot-stamping die using a three- And a method of producing a block. A method for manufacturing a cooling block for a hot stamping mold using a three-dimensional metal printer, the method comprising: fabricating a cooling block with a low-cost material; forming a high-priced material having a high thermal conductivity only in a portion where the lower mold is in contact with the upper mold, Thereby reducing the material cost and maximizing the cooling performance, thereby improving the economical efficiency and work efficiency.
