Before use, it is necessary to check whether there is sufficient heat transfer medium and pressure (that is, the pressure gauge is zero). If not, the machine cannot be forcibly started.

Before use, it is necessary to check whether there is sufficient heat transfer medium and pressure (that is, the pressure gauge is zero). If not, the machine cannot be forcibly started. If possible, it may be possible to connect the mold to be produced with a hot mold below, which can save Extra man-hours to improve efficiency. The first time the machine is connected to the mold, the machine is stopped for a long time, and the mold is changed. The exhaust operation is performed because air is a poor conductor of heat and it will affect the effect of conducting heat. The specific method is as follows:


1 First set the temperature of the Cloud mold temperature machine to zero degrees, and run for 10 minutes after starting;

2. When the pressure shows normal, warm up to 120 ℃, run for 20 minutes, and exhaust;

3. Then adjust the temperature to the normal range of die-casting production (generally 180 ° C ~ 260 ° C). Of course, setting the temperature of the equipment of Klod Machinery also depends on the product process requirements.

4. To prevent the mold temperature machine from accidents, it is necessary to take safety measures and perform regular maintenance on the mold temperature machine.


5. Don't use general organic medium, but use synthetic thermal conductive oil with good thermal stability to reduce fouling;

6.Regularly change the heat transfer oil (the replacement cycle is determined according to the heat transfer oil manual and the supplier's recommendations);

7, after each die, check whether there is mechanical failure and electrical, control problems

Before the formal die-casting, the hot surface of the mold is generally used. Preheating the mold surface alone is likely to cause stress concentration and damage the mold. Therefore, the mold temperature machine should be turned on for at least half an hour before the gas hot mold, so that the mold is heated at the same time inside and outside. Longer is good.


In the die-casting process, the use of a mold temperature machine often brings many advantages: because the mold heat distribution is more uniform, the mold life can be extended, the mold is uniformly and smoothly preheated, and stress cracks are eliminated-flame preheating of the mold often causes localized Local shock caused by thermal shock caused by overheating or gap water cooling, and the preheating of the mold temperature machine is used to overcome this. The amount of mold release agent is reduced, the casting quality is stable, the inspection frequency can be reduced, the inspection cost is reduced, the mold temperature is constant and it is in the process In the interval, the liquid metal is not easy to stick to the mold. With heat-conducting oil, the cooling channel will not rust or scale, and water cooling will easily rust and block the channel.

Quickly preheat the mold purposefully; the mold temperature is constant at the beginning, and the waste is reduced-no need for a lot of mold preheating and low speed injection, the mold temperature machine is automatically controlled, has nothing to do with the production process, so the casting quality is stable.
