Special attention should be paid to the following points in the use of aluminum alloy die casting mould:

1. Clear of the mold parting surface, it is very trouble, also is very easy to overlook, high starting point, if the boss to buy a good pair of mould, so work is easier, if the mould quality is bad, when production have flash or dirt in the mold parting surface, operators should often go to clean up these areas, equipped with a spatula knife at any time. If the flash is not removed in time, the parting surface of the mold is easy to collapse, resulting in aluminum running in the production process. Once this result is caused, no matter how good you are, the possibility of complete repair is very small, not because they do not have the ability. The consequences of running aluminum not only increase the cost of die-casting, waste of white aluminum, product quality is not stable, especially the internal quality, but also increases the difficulty of determining process parameters, the pass rate will drop a lot, from safety considerations, increase the probability of industrial injury. In succession, operators use kerosene thoroughly wash again to the mold parting surface, not only can prevent mould will not be crowded injury, and after cleaning, can be release agent on the die cut of the residue or other vent groove through dirt jam, is advantageous to the gas discharge in injection mold during the process of improving product quality, a team down twice cleaning parting surface is advisable. Let the staff form a good habit.

2. When each team takes over, they should make the inspection according to the "Mold Spot Inspection Table" of the company carefully, and solve the problems in time to avoid causing unnecessary trouble.

3. Use of mold cooling system. The mold cooling water can not only prolong the service life of the mold, but also improve the production efficiency under the condition of correct use. In the actual production, we often ignore its importance. Operators also want to save trouble, and it is too troublesome to connect, so they don't connect the cooling water pipe. Some companies even don't connect the cooling water pipe when customizing the mold in order to save costs, which causes very serious consequences. Mold materials are generally special mold steel through a variety of processing produced, it is a good mold steel also have their use of extreme limit, such as temperature. Mold in the use of the state, if the mold temperature is too high, it is easy to make the surface of the mold core early turtle crack, and some molds have not even more than 2000 mold turtle crack on a large area. Even the mold in the production because the mold temperature is too high the mold core has changed color, after measurement and even reached more than 400 degrees, such a temperature and then encounter the release agent cold state is easy to crack, the production of products are easy to deformation, strain, stick mold and other conditions. In the case of using mold cooling water, the use of release agent can be greatly reduced, so that the operator will not use release agent to reduce the temperature of the mold. Its benefits are to effectively prolong the life of the mold, save the die casting cycle, improve the quality of the product, reduce the occurrence of sticking to the mold and pull and sticking to aluminum, reduce the use of release agent. It can also reduce the loss of ejector and core caused by overheating of mold temperature.

4. The mold must be preheated in the beginning of the production process, to prevent the sudden encounter of hot metal liquid in the cold mold and lead to the appearance of the turtle crack, more complex mold can be used with a blowtorch, liquefied gas, good conditions with the mold temperature machine, relatively simple mold can be preheated by slow injection.

5. If the mould are equipped with a neutron control, it is absolutely forbidden die-casting machine and mold the line between a joint phenomenon, the reason is very clear, in the daily production, it is hard to avoid signal lines touch water, easily broken or joint bandage, resulting in the nipple and machine tool, if error caused by signal, light alarm, automatic stop delay time or signal is disorder, the mold very bad. Cause unnecessary damage. Pay attention to waterproof travel switch.
