Aluminum alloy die-casting mold in the use of the following points to pay special attention to:
1. The mold parting surface cleaning, which is very troublesome, it is easy to overlook, if the boss starting high, buy a good mold, then it seems much easier work, if the mold quality is not good, When the mold parting surface is bound to have a flash or dirt generated, the operator should often go to clean up these parts, at any time with a small blade. If there is no timely removal of the flash, the mold parting surface is easy to collapse, resulting in the production process to run aluminum, once the consequences, no matter how good you repair experts, the possibility of complete repair is very small No, they are not capable. The consequences of running aluminum, not only increased the cost of die-casting, white aluminum waste, product quality is not stable, especially the internal quality, but also to increase the difficulty of determining the process parameters, the pass rate will drop a lot, from the security considerations, Increased the chance of injury. In the shift, the operator applied kerosene thoroughly to clean the mold parting again, not only to prevent the mold will not be crushed, and after cleaning, the mold can be detoxification agent residue or other dirt blocked row Gas tank open up, is conducive to the process of injection of gas within the cavity to improve product quality, a team down to clean the surface twice is appropriate. Let the staff to develop a good habit.
2. Use of mold cooling system. Mold cooling water in the correct use of the case not only extend the life of the mold, but also improve production efficiency. In the actual production, we often ignore the importance of the operator is also easy to handle, then pick up too much trouble, do not take the cooling water pipes, and some companies even in the custom mold when the cost in order to save even not cooling Water, which has caused very serious consequences. Mold materials are generally dedicated mold steel produced through a variety of processing, and even the best die steel also have their use of the limit, such as temperature. Mold in the use of the state, if the mold temperature is too high, it is easy to make the core surface early turtle cracks, and some molds have not even more than 2000 mold turtle cracks on a large area. And even mold in the production because the mold temperature is too high Core have changed the color, measured even up to more than 400 degrees, such a temperature and then encounter the release agent quenching state is prone to turtle crack, the production of products But also easy to deformation, strain, sticky mold, etc. appear. In the case of the use of mold cooling water can greatly reduce the use of release agent, so the operator will not use the release agent to reduce the temperature of the mold. The advantage is to effectively extend the die life, save the die-casting cycle, improve product quality, reduce sticky mold and strain and sticky aluminum situation, reduce the use of release agent. But also reduce the mold temperature overheating caused by the loss of the mandrel and core.
