Title:
HOT PRESS MOLDING DIE, METHOD FOR MANUFACTURING HOT PRESS MOLDING DIE, AND METHOD FOR MANUFACTURING AUTOMOBILE BODY PART
Document Type and Number:
WIPO Patent Application WO/2022/070797
Kind Code:
A1
Abstract:
The present invention comprises at least one main die body (12) formed by a die material for hot press molding. The present invention is provided with a mold surface (13) formed on the surface of the main die body (12), and a refrigerant passage (14) formed inside the main die body (12). The present invention is provided with a heat-conducting body (15) that is formed in a solid shape by a material having a thermal conductivity higher than that of the die material and that is embedded in the main die body (12). The heat-conducting body (15) constitutes a part of a heat transfer pathway (18) from the mold surface (13) to the refrigerant passage (14). It is possible to provide a hot press molding die with which it is possible to prevent "accumulation of heat" on the mold surface.
