Definitions
- the present invention relates to a vacuum die-cast product of an aluminum alloy having excellent mechanical strength and a method for producing the same, and more particularly to a vacuum die-cast product of an aluminum alloy suitable for transportation equipment having high strength and high toughness and its production. About the method. Background art
- Die-casting is a technology for manufacturing metal parts by filling molten metal into the mold at high speed and high pressure. It has higher dimensional accuracy than other manufacturing methods, and has beautiful skin and productivity. Has the advantage of being high.
- the high-speed filling of the molten metal causes the surrounding gas to be entrained in the molten metal, resulting in a large number of air bubbles filled with gas inside the product and inclusions such as oxidized substances formed by the reaction between the gas and the metal.
- These defects not only reduce the mechanical strength of the product, but also the gas-filled bubbles, especially during heat treatment and welding, become blisters due to the expansion of the internal gas, which significantly reduces the mechanical strength. Therefore, the use of the die-cast product as a structural member has been limited.
- the gas contained in the die-cast product includes, in addition to atmospheric components, a combustion gas of a lubricant for a plunger and a release agent for a mold cavity.
- a vacuum die-casting method of reducing the pressure inside the mold cavity and making it has been put to practical use.
- Japanese Patent Application Laid-Open No. 6-126415 discloses a vacuum die force apparatus for reducing the pressure in the cavity and loading the molten metal into the injection sleeve, which includes a fixed type mounted on a fixed platen, and a movable type forming a cavity together with the fixed type.
- An injection sleep communicating with the cavity, a plunger moving forward and backward in the injection sleeve, a holding furnace below the injection sleeve for storing the molten metal, and one end connected to the hot water inlet of the injection sleeve, and the other end connected to the injection sleeve.
- a hot water supply pipe immersed in the molten metal in the holding furnace and a vacuum inside the cavity
- a pressure reducing means for reducing the pressure and loading the molten metal in the holding furnace into the injection sleeve via a hot water supply pipe.
- silicone-based emulsion release agents have been used for die casting of aluminum alloys.
- the silicone emulsion type release agent is obtained by emulsifying a modified silicone oil with an emulsifier using water as a medium.

- there is more CO2 gas than CO2 gas there is a problem that the product becomes brittle during heat treatment and welding.
- the mold cavity has a temperature of about 300 ° C
- the use of an aqueous mold release agent causes almost all of the water to evaporate. Release agent adheres. Since the surface temperature of the mating surface is low, the moisture in the release agent remains without evaporating. For this reason, even if the pressure is reduced after clamping, the release agent is sucked into the cavity from the gap between the movable mold and the fixed mold and continues to evaporate. The same phenomenon occurs when an aqueous release agent adheres to the movable part behind the nest. As a result, the degree of vacuum in the cavity does not decrease and the amount of hydrogen gas generated increases.
- gas-containing pores are often near the surface of the article.
- heat treatment or welding is performed on a product having such gas-containing pores, the gas in the pores expands, and the pores become so-called blisters, which become B-shaped protrusions protruding from the surface of the product.
- Prestars can be the starting point for cracks and fractures when loaded.
- the gas sealed in the pores is hydrogen, it is absorbed by the product during heat treatment or welding, causing deterioration of the product. Therefore, it was found that it is necessary not only to reduce the entrainment of gas during vacuum die casting, but also to reduce the proportion of hydrogen in the entrained gas.

Therefore, in the vicinity of the gate, the part farthest from the gate, and in the middle part, the test pieces were sampled from 3 to 10 places, and the amount and composition of the residual gas were measured for each test piece, and the measurement of each part was performed. Values and their averages need to be determined.
