Shandong Aluminum alloy die-casting is used more and more, but we know how to ensure the efficiency of Shandong Aluminum alloy die-casting! Not only need daily maintenance, but also pay attention to the way of use in the use process!
Then Jinan Hongjie mould Co., Ltd. will take you to know what are the ways to use aluminum alloy die casting?
First, the use of mold cooling system. Mould cooling water can not only prolong the service life of mould, but also improve the production efficiency. In the actual production, we often neglect the importance of it, and operators try to save time. It's too troublesome to connect the cooling water pipes. Some companies even don't use cooling water in order to save costs when customizing molds, resulting in very serious consequences. The material of the die is usually made of special die steel by various treatments. The best die steel has its limit of use, such as temperature. When the mold is in use, if the mold temperature is too high, it is easy to cause turtle cracks on the surface of the mold core early. Some molds even have not had more than 2000 times turtle cracks on a large area. Even in the production of the mold, because the mold temperature is too high, the mold core has changed color. After measurement, it even reaches more than 400 degrees. Such temperature is easy to appear turtle crack when encountering the state of mold release agent chilling again. The products produced are also easy to deform, pull and stick the mold. In the case of using mold cooling water can greatly reduce the use of mold release agent, so that operators will not use mold release agent to reduce the temperature of the mold. The utility model has the advantages of effectively extending the service life of the die, saving the die casting cycle, improving the product quality, reducing the occurrence of die sticking, drawing damage and aluminum sticking, and reducing the use of the release agent. It can also reduce the loss of ejector pin and core caused by overheating of mould temperature.
Second, if the mold is equipped with neutron control, it is absolutely forbidden to connect the signal line between the die casting machine and the mold. The reason is very clear. In daily production, it is difficult to avoid water on the signal line, or the place where the joint is bound is easy to break, resulting in short connection with the machine tool. If the signal is wrong, the alarm will automatically stop, delay the time, and the signal will be disordered, Break the mold. Cause unnecessary loss. Pay attention to waterproof of travel switch.
Third, the mold must be preheated in the process of starting production to prevent the occurrence of tortoise crack caused by hot metal liquid suddenly encountered in the cold mold. For the more complex mold, blowtorch and liquefied gas can be used. For the better condition, mold temperature machine can be used. For the simpler mold, slow injection preheating can be used.
