Abstract: A die having adequate flexibility at an entirety thereof while maintaining rigidity of a design surface is presented. A die is a die for a machine press. The die is a die for pressing a work plate together with a contraposed die and forming the work plate into a target shape. The die is provided with a design block, a positioning block, and a plurality of rods. The design block has a design surface for transferring the target shape to the work plate. The positioning block is used for positioning the die relative to the contraposed die. The design block and the positioning block are connected by the plurality of rods.

Abstract: A method for generating CAD data appropriate for designing an evaporative pattern having a frame structure is provided. The method includes, allocating, generating joint shape data, and extracting rod body data. Rod data includes rod body data representing a shape of a rod body and terminal data representing a shape of a rod terminal disposed at an end of the rod body. In the allocating, a plurality of the rods is allocated so that the rod terminals overlap each other in a 3-dimensional space in computer. In the generating, the joint shape data is generated by merging the terminal data of the plurality of rod terminals overlapped. In the extracting, the rod body data is extracted from the rod data of the rods allocated in the 3-dimensional space. The joint shape data and the rod body data obtained by such processes correspond to the CAD data of the evaporative pattern.
