    Abstract: A casting metal mold made of a copper alloy consisting essentially of 0.01 to 3 wt % of zirconium, 0.03 to 5 wt % of titanium and, as required, 0.03 to 2 wt % of chromium and the balance substantially copper, the copper alloy having a structure in which precipitate phase consisting of compound of copper and at least one of zirconium, titanium and chromium exists, and having a Brinell hardness between H.sub.B 100 to H.sub.B 500 and an electric conductivity between 20 and 80% in terms of IACS. This metal mold suffers only small deformation during casting and, hence, less liable to cause run-out of the melt. The casting obtained by this metal mold, therefore, has no or only slight fins.

    Abstract translation: 一种由铜合金制成的铸造金属模具，其基本上由锆组成为0.03〜5重量％，钛为0.03〜5重量％，根据需要为0.03〜2重量％，余量基本上为铜，铜合金具有 存在由铜化合物和锆，钛和铬中的至少一种组成的沉淀相，其布氏硬度为HB100〜HB500，电导率为I〜20％〜80％的结构。 这种金属模具在铸造过程中只有很小的变形，因此不太容易引起熔体流出。 因此，通过该金属模具获得的铸件没有或仅有微小的翅片。

    Abstract: (A method for reinforcing a refractory mold by wrapping a carbonaceous textile material around the surface of the mold. The textile material may be coated with a binder and the assembly subsequently baked to a temperature sufficient to coke the binder in order to reinforce and mechanically link the textile material) A fiber reinforced hot pressing mold composed of a conventional refractory mold encased by a carbonaceous textile material. The textile material is coated with a binder prior to, or subsequent to, being wrapped around the surface of the mold and then the mold assembly so prepared is baked to a temperature sufficient to coke the binder in order to reinforce and mechanically link the textile material.

    Abstract: A metal mold is prepared by an electrical machining process wherein one of a base metal mold and an upper metal mold is electrically shaped by using an electrode having a desired shape on a surface thereof facing the workpiece, and the electrode then is fitted into the shaped metal mold to make a composite electrode of the two, and if necessary, the opposite surface of the electrode is also shaped. The other metal mold is then electrically shaped by using the composite electrode having the desired shape. With this invention, it is possible to provide a metal mold for thin articles, such as plastic articles.
