０℃位の低融点金属、例えばＮ。<Conventional technology and its problems> Conventionally, a pair of male and female molds, sleeves, and pistons are made of 5K, which is generally used as the material (main mold material).
Because it is D61 (sintered heat-resistant alloy), the pouring temperature is set at 60°C.

のやむなぎに至る。Casting of products using low-temperature molten metal such as ZTI is limited, and casting using high-temperature molten metal of 650 to 2000℃, especially 750℃ or higher, is extremely difficult and difficult due to the material. It was dangerous. That is 750
The high-temperature thermal shock received from the high-temperature molten metal above ℃ causes precipitation at the metal grain boundaries, resulting in poor toughness, resulting in severe erosion of the cavity surface of molds, rapid brittle fracture, and even It causes a complete break in the shape and leads to the loss of limbs.

くする。On the other hand, in the case of the sleeve and piston, core run-out occurs in both, making it impossible to obtain the injection speed of the piston, resulting in poor quality of the product due to insufficient feeder of molten metal, and wear of the sleeve and piston due to uneven wear. , which in turn shortens their lifespan.

ことである。<Means for Achieving the Technical Problem> The technical means taken by the present invention to achieve the above-mentioned problem is to use one or both of a pair of male and female molds and a high-temperature molten metal in the mold. The sleeve and piston to be filled are made of a stability-resistant alloy in which 0.01 to 5 wt% of an oxide is mixed in a dispersed form in a metal base of one of Pt, Ir, or Rh. The female and female dies, the sleeve, and the piston are surface-treated with oxides, nitrides, carbides, etc., which have excellent heat resistance and are not easily corroded by the high-temperature molten metal.
〈実施例〉

からである。The reason for this is that if it is less than 0.01 wt%, the
It lacks strength in the high temperature range of about 0°C. This is because the oxide particles of the finely refined powder, which are resistant to heat, are not uniformly and finely dispersed at the grain boundaries (crystal interfaces) of the metal crystals, so-called Pt, Ir, or Rh. However, if it is left in a high temperature range for a long time, the crystal structure will become coarser, and it will become impossible to maintain the crystal structure, resulting in a circle or 1r.
Or, if it is more than 5wt%, the melting point will increase and the plastic working will become worse. This is because the bonding is greatly hindered by the oxide particles.

出来た。■P mixed with 0.01 to 5 wt% oxide in a dispersed form
The male and female molds, sleeve and piston are made of T-based stability alloy, Ir-based stability alloy or Rh-based stability alloy. Because it is surface treated with oxides, nitrides, carbides, etc. that have excellent heat resistance and are not easily eroded by high-temperature molten metal, it has improved mechanical properties such as hardness and fracture toughness compared to conventional manufacturing equipment made of 5KD61 material. The manufacturing equipment is excellent in properties and has sufficiently high heat resistance such as thermal shock resistance that can withstand high-temperature thermal shock, and stability for long-term use. Therefore, high-temperature molten metal products with great durability and thermal shock resistance have made it possible to cast products under severe operating conditions, such as using high-temperature molten metal of about 650 to 2000°C and solidifying it while applying pressure. We were able to develop and provide manufacturing equipment.
