How to extend the manufacturing life of Aluminum Die Casting Parts Tooling products

(Summary description)In the process of die casting production, the formed Aluminum Die Casting Parts Tooling products actually have to bear a lot of pressure, the molding conditions are very harsh, and they are repeatedly affected by mechanical wear, chemical corrosion and thermal fatigue, and often excessive thermal stress occurs , resulting in cracks on the surface of the mold, what problems should be paid attention to in the use and maintenance of these die-casting molds?

Aluminum Die Casting Parts Tooling products

1. The shell and aluminum foil appearing in the mold use are quickly removed to prevent screwing into the mold
In the process of using Aluminum Die Casting Parts Tooling products, due to various reasons, the mold can be covered, aluminum skin, at this time, if not recycled, the production will continue, crushing the mold, especially in the case of sliding parts , If the slideway is put into the aluminum skin, etc., the combined force of the pressure casting machine is very large, and it is easy to slide and break.
Therefore, in the face of such a problem, the mold must be sorted out immediately, and the cause must be found to repair the mold in time. Otherwise, if the mold is not repaired after it is broken, it will have a serious impact on the life of the mold.
2. Reduce the rapid cooling and rapid heating of Aluminum Die Casting Parts Tooling products, continuous production, in the state of cold mold, do not tell the injection mold in the die casting process, the mold is in a reciprocating fatigue state due to heat shrinkage, and the temperature of the mold cavity is basically 160 degree - 350 degree change multiple times.
In addition, when starting production in a cold mold state, the mold temperature rises from a low temperature, the temperature difference increases, the mold fatigue increases, and the mold life is shortened. Therefore, during die-casting production, try to continue production as much as possible to reduce the rapid cooling and heating of the mold and prolong the life of the mold.
In addition, in the cold mold state, the mold does not reach the temperature during normal production, and the gap between the various parts of the mold is relatively large. Cap holes and other parts are easy to penetrate into the aluminum skin, destroy the mold, and affect the life.
3. Reduce the compression speed, reduce the compression ratio, and reduce the impact of the mold
During die-casting production, the injection speed not only affects the filling speed of the die-casting, but also affects the shilling speed in the injection. Therefore, due to the high pressure speed, the fast speed of the irradiated port in the compression, the strong impact peak value of the mold brush, the impact force on the mold increases, and the mold life is greatly reduced. When adjusting the die-casting process, it is very important to reduce the injection speed as much as possible, increase the life of the mold, and improve the economic effect of die-casting while ensuring the quality of the product.
Now, the press is equipped with a pressure braking device, which reduces the impact peak value and the impact force of the mold, which is beneficial to improve the life of the mold. Injection is a more important indicator than pressure in the die casting process, but it not only affects the quality of the mold, but also affects the life of the mold. also have a great impact.
4. Minimize the temperature of molten aluminum and increase the service life of Aluminum Die Casting Parts Tooling products The injection temperature of molten aluminum during die-casting production will not only affect the casting, but also the service life of the mold.
Generally, when pressing the gun, the temperature generated by the molten aluminum is 630~720 degrees. For different components, we choose the temperature generated, and the selection is as low as possible. While saving this energy, it can prolong the service life of the gun type.
The higher the temperature of the molten aluminum, the more intense the erosion of the mold, so the wider the range of changes in the temperature field of the mold, the more intense the thermal expansion and contraction, the greater the fatigue of the mold, and the easier it is to be damaged. Properly lowering the temperature of the molten aluminum will help prolong the mold. .
5. In order to strengthen Aluminum Die Casting Parts Tooling products, regular maintenance and treatment of regular cavity tempering stress die-casting molds are continuously produced under high pressure, high speed, and high temperature, and the use conditions are relatively harsh. During use, the mold will be damaged, defective, etc. , In order to strengthen the protection of the mold, it is very important to regularly replace the maintenance, damaged parts, vulnerable parts, cleaning, top punching, etc. of the mold. It is very important to ensure the reliability of the mold press gun production, and can also extend the service life of the same mold .
