1). Wall thickness requirements for Die casting of aluminum alloy

The shape and structure requirements of aluminum alloy die casting are: eliminating internal side concave; avoiding or reducing core pulling position; avoiding core cross; reasonable aluminum die casting structure can not only simplify the structure of die casting, reduce manufacturing cost, but also improve casting quality.


The wall thickness of aluminum alloy die casting should not be too thin, which will lead to poor filling of aluminum liquid, difficult forming, poor fusion of aluminum alloy, easy to produce defects such as cold insulation on the surface of the casting, and bring difficulties to the die casting process; With the increase of wall thickness, the defects such as porosity and shrinkage cavity in the aluminum die casting increase. Therefore, on the premise of ensuring sufficient strength and rigidity of the casting, the wall thickness of the casting should be minimized and the thickness of the section should be kept uniform. In order to avoid the defects such as shrinkage porosity, the thickness of the thick wall of the casting should be reduced (reduced) and the reinforcement should be increased. For the large-area plate thick wall casting, Set bars to reduce wall thickness of castings.


Wall thickness requirements for aluminum alloy die casting design: wall thickness (commonly called wall thickness) of aluminum die casting is a factor of special significance in the die casting process, which is closely related to the whole process specification, such as the calculation of filling time, the selection of internal gate speed, the calculation of solidification time, the analysis of mold temperature gradient, the role of pressure (final specific pressure), the length of mold retention time, and the casting The results show that the mechanical properties of aluminum die casting are obviously decreased, the compactness of Thin-walled Casting is good, and the strength and pressure resistance of casting are improved.


2). Temperature controlling in alloy die casting process

In the production process of aluminum alloy die casting, temperature is one of the central process elements. The quality of temperature control of die casting die directly affects the quality of products and production power. In this paper, based on the actual situation of aluminum alloy die casting, the temperature control method of aluminum alloy die casting die is analyzed in order to complete the heat balance of die and deal with the problem of heat joint.


1. Foreword

With the rapid development of automobile industry, it brings more opportunities and new challenges to die casting industry. In the production of die casting, die temperature has an important influence on the quality of casting, die life and production beat. Therefore, in modern die casting technology, the control of die temperature has become an indispensable technology. This paper expounds the importance, principle and operation of die casting die temperature, as well as a set of temperature control methods selected for the control methods Brief analysis.


2. Importance and control principle of die casting die temperature

(1) The importance of die casting temperature

Die casting mold is the molding process equipment in the casting production process. Whether the temperature field established in the mold is stable or not has an important influence on the casting quality, production power and the service life of the mold, which is directly related to the cost and economic benefit of the casting production. The temperature field in the mold should be within the scale required by the process, so that the castings with qualified appearance and internal quality can be obtained. On the contrary, too high temperature will cause defects such as scratch and bubble, prolong the cooling time and reduce the production power; too low temperature will cause defects such as cold separation, insufficient pouring and air hole. If the die-casting die is produced in high temperature and high pressure environment for a long time, coupled with the unstable temperature field of the die, the long-term periodic thermal expansion and contraction, the die-casting die will be simpler and fail, greatly shortening the service life and reducing the production power.

(2) Temperature control principle of die casting die

In the process of casting, the heat exchange between the mold and the liquid metal reaches the ideal heat balance, that is to say, the heat absorbed and discharged by the mold is equal to the dynamic heat balance. After the process is selected, the mold temperature reaches the scale of the casting working temperature, and the local simple hot spot is cooled at a fixed point to promote the composition of the heat balance.


3. Hot Festival

(1) Place of occurrence: the casting structure has the highest temperature in the process of die casting, which is easy to form shrinkage cavity, shrinkage porosity and place of stress concentration in the process of cooling.

(2) Control method - cold engine

In order to achieve the purpose of water saving, the point cooler adopts the method of water circulation. In order to ensure the full pressure, a header is added.

(3) High pressure spot cooling is added to the core at the hot spot of the casting.

(4) Point cooling water treatment: point cooling water will encounter sudden cooling and sudden heating in the cooling pipeline, and the pipeline is fine. The old type of water treatment generally uses softening treatment, which often fails to meet the water quality requirements in production, and the point cooling pipe is blocked frequently, resulting in huge loss of human, material and financial resources. Generally, RO reverse osmosis water treatment device is used to treat point cooling water into pure water.


4. Heat balance

(1) Principle: in the process of die casting production, the heat absorbed by the mold and the heat discharged should be kept consistent, so as to prevent the mold from getting colder and hotter, and reduce the casting defects such as shrinkage cavity, shrinkage porosity and porosity due to the uneven temperature of the mold. Improve the appearance and internal quality of the casting, the service life of the die and the production power. To reach the heat balance is to cool the mold at high temperature and warm it at low temperature.

(2) Control method - die casting die temperature machine

The mould temperature machine is divided into water type and oil type. The water type is generally selected when the control temperature is about 160 ℃ and the environmental requirements are high. The oil type is generally selected when the temperature is higher than 160 ℃. Generally, the main function of die temperature machine is to use cold die, which can not adjust and control the temperature in the process of die casting production.

(3) Control method mold cooling unit

The mould cooling unit is used together with the mould cooling circulating water to cool the parts with high mould temperature, so as to maintain the heat balance of mould cavity temperature.


5. Temperature monitoring method of die casting die

(1) Hand held thermal imager

Each class will have a thermal imaging test and adjust the mold according to the temperature condition

(2) Thermocouple or thermal imager temperature monitoring system.

According to the mold condition, the thermocouple is embedded in the mold or the thermal imager is placed on the top and left and right sides of the mold. The temperature distribution of the mold is monitored in real time through the control system. After the analysis of the monitoring data, the mold temperature is adjusted to complete the temperature monitoring of the mold.


6. Conclusion

Mold temperature is one of the most important process parameters. It not only determines the casting quality, but also seriously affects the service life and production power of the mold. Therefore, to ensure that the parameters can be controlled, the automatic temperature control system should be used as far as possible. The temperature control of die-casting die is a combination of many methods. It can not be considered that only one temperature control method can control the temperature of die-casting die. Different temperature control methods should be adopted according to the different conditions of die-casting production process and die-casting die. With the development of die-casting technology, new temperature control methods are constantly updated. The application of new methods will certainly further improve the level of mold temperature control, and contribute to the production of faster and better die-casting parts.
