Abstract: front page image
(EN)A process for producing a forming metal mold in which the occurrence of failure, such as collapse of sand mold at the time of prototype pickup, can be avoided; and a forming metal mold capable of clear transfer of pattern to molded items. A reticular member is fixed to the entirety or a part of the molding surface of a prototype, and with the use of the prototype, there is produced a sand mold having an uneven pattern on its molding surface. With the use of this sand mold, there is cast a forming metal mold having the uneven pattern on its molding surface. The reticular member consists of a meshed flexible synthetic resin sheet provided with a multiplicity of mesh openings.
(FR)L’invention concerne un procédé de fabrication d’un moule de métal de conformage dans lequel on peut éviter l’apparition de défaillance, comme l’effondrement du moule de sable au moment de la saisie du prototype ; et un moule de métal de conformage capable de transférer de façon nette un motif à des articles moulés. Un élément réticulaire est fixé à la totalité ou une partie de la surface de moulage d’un prototype, et à l’aide du prototype on produit d’un moule de sable ayant un motif irrégulier sur sa surface de moulage. L’utilisation de ce moule de sable permet de couler un moule de métal de conformage ayant le motif irrégulier sur sa surface de moulage. L’élément réticulaire se compose d‘une feuille de résine synthétique flexible en mailles pourvue d’une multiplicité d’ouvertures de mailles.
(JA) 原型の抜き取り時の砂型の崩れ等の不具合の発生を防止できる成形用金型の製造方法、成形品に模様を鮮明に転写できる成形用金型の提供。  原型の成形面の全面又は一部に網状部材を固定し、該原型を用いてその成形面に凹凸模様を有する砂型を作製し、更に、前記砂型を用いてその成形面に前記凹凸模様を有する成形用金型を鋳造し、網状部材は、多数の網孔を形成した網目状の可撓性を有する合成樹脂シートから構成した。
