Abstract

PURPOSE:To obtain a liquid-metal-forged produce consisting of an ultrafine structure and having high quality by using ceramic molds to one or both of the male or female mold of a forming mold thereby widening the range for adjusting the cooling rate by a cooling mechanism. CONSTITUTION:The male mold a1 is formed of a heat resisting metal such as high chromium molybdenum steel and is disposed internaly with the cooling mechanism 1 and a heating mechanism 1'. The forming part a2' of the female mold a2 is formed of ceramics. The cooling mechanism 2 and a heating mechanism 3 are adequately disposed in said part a2'. A molten metal (m) is poured into the part a2' while the part a2' is adequately cooled and heated by the mechanism 2 and mechanism 3 of the mold a2 and thereafter the mold a1 is mated with the female mold. The metal (m) is cooled and pressurized until the temp. falls down to the solidifying range of the metal (m), by which the product is formed.

Description

【発明の詳細な説明】本発明は溶鍛用成形型に関する。[Detailed description of the invention] The present invention relates to a mold for hot forging.

溶鍛法は雄雌両型を組とする成形型内に溶湯を注入し、
線型により溶湯に圧力及び冷却をかけながら固相、液相
が共存する凝固区間及び凝固範囲まで降温して金属成品
を製造するものであるが、その加圧及び冷却の速度調整
は成品組織の超微細化に大きく影響し重要である。The hot forging method involves injecting molten metal into a mold that has both male and female molds.
Metal products are manufactured by applying pressure and cooling to the molten metal using a linear method and lowering the temperature to the solidification zone and solidification range where the solid phase and liquid phase coexist, but the speed adjustment of the pressure and cooling depends on the superstructure of the product. This is important because it has a great influence on miniaturization.

しかるに従来の成形型は雄雌両型を共に耐熱金属材でも

耐久性低下の原因となる不具合があった。However, in conventional molds, both the male and female molds are made of heat-resistant metal materials, and as a result, the overall cooling rate tends to be rapid, making it difficult to adjust the speed and causing a decrease in the durability of the mold. There was a problem.

本発明は斯る従来事情に鑑み、前記不具合を解消して冷

ことを特徴とづる。In view of the conventional circumstances, the present invention aims to eliminate the above-mentioned problems, facilitate the adjustment of the cooling rate, make it possible to manufacture high-quality products, and provide a mold with high durability. The mold of the present invention has one or both of the female and H1 molds in the set made of ceramic material to provide heat retention, and both molds are provided with heating and cooling mechanisms.
This is called a characteristic.

Be free. The molding part (a2') of the female mold (a2) is a ceramic mold, and a cooling mechanism (2) and a heating mechanism (3) are appropriately disposed within this molding part (a2').

m) is cooled and the temperature is lowered to the solidification zone of the molten metal (m) (290° C. to 350° C. in the above material) while applying pressure to form a finished product (M).

細組織からなる高品質な溶鍛成品が得られる。In the present invention, one or both of the male mold and the female mold are ceramic molds as in the case of vaporization, so the ceramic mold alleviates the rapid increase in cooling rate within the mold, and therefore the cooling rate due to the cooling mechanism. The adjustment range is widened, and the adjustment operation, especially fine adjustment, becomes easier, and the cooling rate can be easily set according to the product shape and material quality, and high-quality melt-forged products with ultra-fine structures can be obtained. It will be done.

又、成形型は雄型により加圧されるが、前記冷却速度の

依って所期の目的を達成し得る。Therefore, the intended purpose can be achieved.
