Most people may think that the mold temperature machine is only used in the field of plastic injection molding, in fact, otherwise the mold temperature machine is also used in the field of die casting, so how to use die casting in the field of mold temperature machine? What are the advantages?

Correct use of die casting industrial temperature machine method

1. Before using the mold temperature machine, it is necessary to check whether there is enough heat transfer medium (oil or water) and whether there is pressure (i.e. the pressure gauge is zero). If there is any abnormality, the machine cannot be forced to start, otherwise it will damage the machine and even cause a safety accident.

2. In formal die casting, a hot die on the die surface is generally used. Preheating only the surface of the mold is easy to cause stress concentration and damages the mold. Therefore, the mold temperature machine should be turned on at least half an hour before the gas heats the mold, so that the inside and outside of the mold are heated at the same time, and the stress generated by the mold meat is small, which is beneficial to prolong the life of the mold.

3. If possible, the produced mold can be connected to the mold heat machine below, saving extra time and increasing speed.

4. If the machine is connected to the mold many times, the machine will be shut down for a long time, the mold will be replaced, and the exhaust operation should be carried out--because the air is a poor thermal conductor, which will affect the effect of thermal conductivity. The specific method is as follows:

• First, set the temperature of the mold temperature machine to zero, and start running for 10 minutes;

• When the pressure shows normal, then heat to 120°C, run for 20 minutes, and discharge;

• Then set the temperature within the normal range of the die casting process (generally 180°c ~ 260°c), of course, the temperature needs to be set according to the product process requirements.

• Safety measures need to be taken to prevent mold temperature machine accidents, and regular maintenance of mold temperature machine.

Ways to eliminate security risks:

Accidents here refer to mechanical failures and safety incidents. The heat transfer oil used in the mold temperature machine is organic. Under certain conditions, the heat transfer oil will burn, and the working temperature of the die casting is also high, so it can be illuminated with bright light for safety. Therefore, when using the mold temperature machine, it is necessary to understand what hidden dangers exist and take corresponding safety measures:

1. The mold temperature machine should be kept away from heat sources (such as furnaces and holding furnaces) as far as possible, on the one hand to prevent the heat transfer oil from catching fire, and on the other hand to prevent the temperature from being too high and the mold temperature being too high and the premature aging of the electronic components of the machine;

2. The mold connection pre-pipe or insulating pipe must be used to prevent leakage and can withstand temperature and pressure (the temperature exceeds 245 ° C, only metal pipes can be used. Some mold temperature machines, piping machines emit dense Smoke, while the mold temperature machine is very close to the furnace, the temperature of the die-casting alloy liquid is generally above 600 ° C, which is easy to burn fire and dangerous;

3. Regularly check the external pipe connections and internal pipes of the mold tempering machine to ensure that the joints are free of leakage;

4. It should not be used as a general medium, but synthetic heat transfer oil with good thermal stability should be used to reduce the scale;

5. Regularly replace the heat transfer oil (the replacement cycle should be determined according to the heat transfer oil manual and the supplier's recommendations);

6. Check for potential mechanical failures as well as electrical and control issues after each demold.
