Production manner of the sublimation pattern and the sublimation pattern and production manner of the die which uses the sublimation pattern

摘要

The lightweight die which has necessary rigidity is implemented. First, cutting the evanescent material lump, it produces the prototype of the sublimation pattern. The prototype, as it has the cylindrical section of the multiple manuals, has multiple block sections which the relative location is fixed by being locked to the network structure and that network structure of 3 dimensions which the concatenated dot which concatenates the destal of the cylindrical section has been distributed inside 3 dimensional spaces. Next, the cylindrical section of the part which forms prototype removing one part at least at least, displacement in the cylinder component. Next, full mold casting process is executed making use of the sublimation pattern displacement to the cylinder component. The physical relationship of the block section where the formation aspect and the like which is necessary for the die is formed is locked with the network structure of 3 dimensions, necessary rigidity is guaranteed. Because network structure of 3 dimensions is used, the die is lightened. Because displacement in the cylinder component, the capacity which is generated when executing the full mold casting process is suppressed, decrease of casting quality is prevented.
