Aluminum alloy die-casting products are mainly used in electronics, cars, motors and some communication industries. Of course, the primary use is still in the parts of some equipment. So what should we pay attention to in the die-casting of aluminum alloy?
One, consider the issue of mold release,
1. Consider the wall thickness of aluminum alloy die-casting. If the thickness is too large, it will affect the filling.
2. Try to prevent the structure from appearing that leads to the messy structure of the mold, and have to use multiple core-pulling or spiral core-pulling
Fourth, some die castings may have special appearance requirements, such as oil injection
3. Consider the mold problem when designing. If there are multiple core-pulling positions, try to put both ends, preferably not in the lower position, which will cause problems when aluminum alloy die-casting takes a long time.5.

5. It is very troublesome to organize the parting surface of the mold, and it is also very simple to ignore. If the boss has a high starting point and buys a good mold, then the operation will be much easier. If the quality of the mold is not good, it will be produced. Sometimes there will be flashes or dust on the parting surface of the mold. The operator should always tidy up these parts and equip a small spatula at any time.
If the flash is not removed in time, the parting surface of the mold is simply collapsed and formed to run out of aluminum during the production process. Once this result is formed, no matter how good a mold repair expert you are, the possibility of a complete repair is very small. Yes, it's not that they have no skills.If the flash is not removed in time, the parting surface of the mold is simply collapsed and formed to run out of aluminum during the production process.

Aluminum alloy die casting
The results formed by running aluminum not only increase the cost of die casting, waste aluminum, and the product quality is also unstable, especially the internal quality, and it increases the difficulty of determining the process parameters, and the pass rate will drop a lot. From safety considerations, Increased the chance of presenting a work injury.The results formed by running aluminum not only increase the cost of die casting, waste aluminum, and the product quality is also unstable, especially the internal quality, and it increases the difficulty of determining the process parameters, and the pass rate will drop a lot.

During the handover, the operator thoroughly cleans the parting surface of the mold with kerosene, which not only prevents the mold from being crushed, but also prevents the mold from being blocked by the residue of the release agent or other dirt by cleaning. The exhaust groove is opened, which is conducive to the discharge of gas in the cavity during the injection process and improves the product quality. It is advisable to clean the parting surface twice in a team. Let employees develop an outstanding habit.
1. When each team takes over, check carefully according to the "Mold Check List" of our company, and solve the problems in time, so as not to cause unnecessary trouble for yourself.
2. Application of mold cooling system. When the mold cooling water is used correctly, it not only extends the service life of the mold, but also improves the production efficiency. In actual production, we often neglect its importance. The operators also try to save energy. If it is too troublesome to connect and connect, they will not connect the cooling water pipe. Some companies even save costs when customizing molds. Cooling the water, and then formed a very serious result.
The mold materials are generally made of special mold steel through various processes. No matter how good the mold steel is, there are limits to their use, such as temperature. When the mold is in use, if the mold temperature is too high, it will simply cause the mold core to show cracks early, and some molds may even show large areas of cracks before they exceed 2000 mold times.
Even during the production of the mold, the color of the mold core changed because the mold temperature was too high. Through measurement, it reached more than 400 degrees. Such a temperature would easily show tortoise cracks when the mold release agent was chilled. The product produced It also shows simple deformation, strain, and sticking.

3. It is necessary to preheat the mold during the production process of the mold to prevent the appearance of turtle cracks when the cold mold suddenly encounters hot molten metal. The more messy mold can use blowtorch, liquefied gas, and the conditions are good. With a mold temperature machine, relatively simple molds can be preheated with slow injection.
4. If the mold is equipped with neutron control, pay attention to absolutely prevent the signal line between the die-casting machine and the mold from being connected. The reason is clear. In daily production, it is difficult to prevent the signal line from getting water, perhaps the connector is bandaged. The local is simply broken.
Then it forms a short connection with the machine tool. If there is a signal error, it will alarm and stop the machine automatically to delay the time, or the signal will be disordered and the mold will be broken. Form unnecessary losses. Pay attention to the waterproof of the travel switch.
