1 The current status of the development and application of high vacuum die casting technology and high strength and toughness casting alloys
The high vacuum die casting method is to extract the gas in the cavity to keep the filled cavity in a vacuum state, and the molten metal is filled in the vacuum state. Since it is necessary to ensure that less gas can be involved in the filling process, the mechanical properties of the casting are also relatively required. High, which increases the difficulty of casting work forming to a certain extent. Like the ordinary die-casting method, the high-vacuum die-casting method is relatively simple to operate and has a relatively high production efficiency. Therefore, the high-vacuum die-casting method has been widely used since its emergence, and it has also shown a very strong vitality. With the continuous progress and development of science and technology, the continuous optimization of vacuum die-casting technology has made high-vacuum die-casting technology widely used. How to make full use of the cost advantages of high vacuum die-casting technology has attracted widespread attention in the field of technical research and production.
There are many problems in the application of high vacuum die-casting technology. The existence of these problems largely affects the further development of the industry, especially the further development of the foundry industry. The more obvious problem is how to keep the cavity in a vacuum state. Casting molding requires that the cavity must be kept in a vacuum state. The air in the melting furnace must be evacuated. At this stage, the general method is to connect the melting furnace to the riser pipe and the injection chamber. The air in the melting furnace is evacuated, and when the melting furnace reaches the vacuum state, the molten metal is sucked into the injection chamber. When the injection chamber reaches the vacuum state, the die-casting work can be completed. However, in the actual casting process, a common problem is that the melting furnace is difficult to reach the vacuum state, especially when the molten metal is input, air is usually brought in. The existence of air has an extremely adverse effect on the molding of the casting. Ensure the quality of castings. In addition, in the actual application of high vacuum die casting technology, the requirements for the mechanical properties of castings are also relatively high. The mechanical properties refer to the mechanical characteristics of the material under various external loads under different environments. The mechanical properties are difficult to guarantee during the die-casting process. They are affected by brittleness, strength, plasticity, hardness, toughness, fatigue strength, elasticity, The requirements for ductility, rigidity, and yield strength or yield stress have an extremely adverse effect on the full application of high vacuum die casting technology, and also have an adverse effect on the further development of the current foundry industry.

With the vigorous development of industry, industry has become an important industry in the country’s comprehensive national strength, which is conducive to improving the country’s comprehensive economic level, promoting further social and economic development, and providing sufficient impetus for social construction. However, with the vigorous development of the industry, the problems of the industrial casting process have become more and more prominent, which has become one of the important factors affecting the further development of the industry. In order to promote the further development of the industry and continuously expand the application range of die castings, the mechanical properties of the castings must be improved.
