Patent ID: 7920937

Claim:
A method for producing a mold by computer-aided design including a preliminary step in which body portions of the mold are broken down into elementary strata, followed by steps including manufacture of the elementary strata to form manufactured strata and reconstruction of the mold by superposing and assembling the manufactured strata, wherein the method comprises the steps of: defining a fluid transport circuit in the mold; breaking down the fluid transport circuit into a plurality of elementary chambers as part of the break-down of the mold and during the break-down of the mold; producing the elementary chambers in the manufactured strata during the manufacture of the manufactured strata; and completely reconstructing the fluid transport circuit during the superposition and the assembly of the manufactured strata; breaking down an isolating circuit coupled with the fluid transport circuit into a plurality of elementary isolating chambers as part of the break-down of the mold and during the break-down of the mold; producing the elementary isolating chambers in the manufactured strata during the manufacture of the manufactured strata, simultaneously producing the elementary chambers and the elementary isolating chambers during the manufacture of the manufactured strata; reconstructing the isolating circuit during the superposition and the assembly of the manufactured strata, wherein the elementary isolating chambers are placed in fluid-tight communication, simultaneously producing the fluid transport circuit and the isolating circuit; and combining the elementary isolating chambers of the isolating circuit to form a thermal barrier between the fluid transport circuit and side and bottom portions of the mold.
