Abstract
A hot press forming die includes a die main body () made of alloy tool steel, and a number of forming projections () projecting on the die main body and configured to form a forming surface () that comes into contact with a heated metal plate material that is an object to be formed and form a refrigerant passage through which a cooling medium flows. The die main body includes a first forming portion () in which the forming surface is formed to extend in a direction intersecting a forming direction of the metal plate material, a second forming portion () in which the forming surface is formed to extend in the forming direction, and a third forming portion () configured to connect the first forming portion and the second forming portion such that the forming surface becomes a convex surface. The forming projection provided on the third forming portion is formed to be a projecting strip extending between the first forming portion and the second forming portion. It is possible to provide a hot press forming die for which forming convex portions with a high hardness can easily be formed.
