Two interdigitated dies are formed and between them A sheet metal is placed in the die and heated so that it conforms to the shape of the die. Canada The heating wires 6 extend parallel to each other and are uniformly spaced apart from the surface 4. and is held to the ends 18 and 10 of the mold 2 by taber plugs 12. heating w The wire 6 is generally a nichrome wire and is encapsulated by a tube 14. tube 14 is generally a plastic, which is burned during the curing of the ceramic. Disappears by burning.
チューブ14内に被包された加熱ワイヤ6は、セラミックが鋳型内に配置される 闇数列のロッド16により所定の位置に保持される。各列のロッド16は鋳型2 のIllに係合する両端に於てねじ2′0により取り外し可能に保持された棒体 の形態をなす棒状支持体18より下方へ延在している。これらの棒状支持体18 は加熱ワイヤ6に対し直角に延在しており、各棒状支持体により支持された幾つ かのロッド16は各ロッドがそれぞれ一つの加熱ワイヤに係合してそれらを互い に所定の距離にて隔置された位置に保持するよう、一様に隔置されている。複数 個の互いに隔置された棒状支持体18及びロッド16により、各加熱ワイヤ6は それが所定の位置に固定的に保持されるようその長さ方向に沿う互いに隔置され た幾つかの位置に於て支持されている。もっとも各加熱ワイヤは鋳型の表面4の 形状に一致するよう湾曲されている。棒状支持体18の数は鋳型の表面4の不規 則性及び加熱ワイヤ6の剛性に応じて変化されてよい。全てのロッド16の下端 は鋳型の表面4より一様に隔置されている。The heating wire 6 encapsulated within the tube 14 is placed in a ceramic mold. It is held in place by a dark sequence rod 16. Each row of rods 16 is connected to the mold 2 A rod removably held by screws 2'0 at both ends engaging Ill of It extends downward from a rod-shaped support 18 in the form of. These rod-shaped supports 18 extends perpendicularly to the heating wire 6, and is supported by each rod-shaped support. The rods 16 each engage one heating wire to connect them to each other. and are uniformly spaced to maintain them in positions spaced apart at a predetermined distance. multiple Each heating wire 6 is spaced from each other along its length so that it is held fixedly in place It is supported in several positions. However, each heating wire is connected to the surface 4 of the mold. Curved to match the shape. The number of rod-shaped supports 18 is determined according to irregularities on the surface 4 of the mold. It may be changed depending on the rigidity of the heating wire 6 and the rigidity of the heating wire 6. Lower ends of all rods 16 are uniformly spaced from the surface 4 of the mold.

ダイス型構成材料であるセラミック材料が鋳型内に配置され、加熱ワイヤ6及び ロッド16の下端を囲繞する。一般に鋳型はセラミック材料が鋳型内を完全に充 填し加熱ワイヤを充分に埋設し得るよう振動される。ダイス型が使用される際に 有効に機能する成形面が形成されるためには、セラミックは鋳型の表面に係合す る領域に於て開所のない表面を形成しなければならない。セラミックが鋳型内の 所定の位置に配置され加熱ワイヤを所定の位置に保持し得るに充分な程硬化した 後、全てのロッド16に取付けら、れた紐24がロッドの上端に於て解除され、 次いで加熱ワイヤをセラミック内の所定の位置に残したままロッド16がセラミ ックより引き抜かれる。次いで所望のダイス型の厚さになるまで鋳型がセラミッ クにて充填される。この場合追加されるセラミックの一部はロッド16により形 成された孔を充填する。紐24はそれにより応力が発生されることがないのでセ ラミック内に残されてよく、その場合紐はセラミックの硬化中に燃焼によって消 失する。A ceramic material, which is a die mold constituent material, is placed in the mold, and heating wires 6 and It surrounds the lower end of the rod 16. In general, molds are made so that the ceramic material completely fills the mold. The heating wire is then vibrated to ensure sufficient embedding of the heating wire. When a die mold is used In order to form an effective molding surface, the ceramic must engage the surface of the mold. The surface shall be free of openings in the areas covered by the material. ceramic in mold placed in place and cured sufficiently to hold the heating wire in place After that, the strings 24 attached to all the rods 16 are released at the upper ends of the rods, Rod 16 is then inserted into the ceramic, leaving the heating wire in place within the ceramic. It is pulled out from the rack. The mold is then molded with ceramic until the desired die thickness is achieved. It is filled in the tank. In this case, a portion of the added ceramic is shaped by the rod 16. Fill the holes created. The string 24 is separable because no stress is generated thereby. may be left in the ceramic, in which case the strings are extinguished by combustion during the curing of the ceramic. lose
かくして形成されたセラミック製のダイス型を鋳型2より取出す場合には、加熱 ワイヤ6の端部が鋳型2の端壁8及び10より自由に引き抜かれ得るよう、テー バプラグ12が端壁8及び10より解除される。上述の鋳造装置をより一般的な 用途に適用し得るようにすべく、個々のロンド16は棒状支持体18にねじ込ま れたねじ34により棒状支持体に対し保持されてよい。かかる構成によれば、成 形面の異なる種々のダイスをを製造し得るようロッドを個々に調節することがで きる。尚以上に於ては0ツドは中実のロッドであるものとして説明したが、ロッ ドは重最低減の目的でチューブであってもよく、チューブも上述の中実のロッド と同様の要領にて機能する。When taking out the ceramic die mold thus formed from the mold 2, heating is required. The tape is attached so that the ends of the wire 6 can be freely pulled out of the end walls 8 and 10 of the mold 2. The plug 12 is released from the end walls 8 and 10. The above-mentioned casting equipment can be converted into a more general The individual ronds 16 are screwed into a rod-like support 18 for application adaptability. It may be held to the rod-shaped support by screws 34 provided therein. According to this configuration, the The rods can be individually adjusted to produce dies with different shapes. Wear. In the above explanation, it is assumed that the rod is a solid rod. The rod may be a tube for the purpose of weight reduction, and the tube may also be a solid rod as described above. It functions in the same way.
また以上の説明に於ては、加熱ワイヤはただ単に加熱ワイヤであるものとして説 明したが、上述の如く加熱ワイヤは一般にプラスチックのカバーにて被包されて いる。鋳型内のセラミックが硬化する際、加熱ワイヤを被包するプラスチックチ ューブは燃焼により消失し、加熱ワイヤはプラスチックチューブにより形成され た空間内に遊嵌状態にて残存する。In addition, in the above explanation, the heating wire will be explained as simply being a heating wire. However, as mentioned above, the heating wire is generally covered with a plastic cover. There is. As the ceramic in the mold hardens, a plastic film encasing the heating wire is removed. The tube disappears by combustion, and the heating wire is formed by a plastic tube. It remains in the space in a loosely fitted state.
