Abstract:
1. A method for designing a mold that is used to form a molded product and is manufactured by removing a cutting area from a mold material, the method comprising: generating, based on three-dimensional computer aided design (CAD) solid data of a first mold part stored in a part database, first three-dimensional computer-aided design (CAD) solid data representing geometry of a non-cutting area for designing the first mold part of a mold, and second three-dimensional computer-aided design solid data representing geometry of the cutting area for processing a cavity to insert the first mold part in a second mold part of the mold; storing the generated first three-dimensional computer-aided design solid data in association with the generated second three-dimensional computer-aided design solid data in a structure information database; retrieving, based on input of part information for designing a mold, corresponding first three-dimensional computer-aided design (CAD) solid data representing geometry of the non-cutting area of the mold for designing a retrieved first mold part from the part database; checking whether retrieved second three-dimensional computer-aided design solid data representing geometry of the cutting area for processing a cavity to insert the retrieved first mold part to a second mold part of the mold is stored in the structure information database in association with the retrieved three-dimensional computer aided design solid data; and if said checking determines that the retrieved second three-dimensional computer-aided design solid data is stored in the structure information database, designing the mold using the retrieved first three-dimensional computer-aided design solid data representing the geometry of the non-cutting area for designing the first mold part, and the retrieved second three-dimensional computer-aided design solid data representing the geometry of the cutting area for processing a cavity to insert the first mold part in the second mold part of the mold, wherein the first mold part and the second mold part are in a mating relationship.
