What do I need to pay attention to when producing gravity casting molds?

In gravity casting, there are some details that we need to pay attention to, which can enhance our understanding of gravity casting, not only the whole, but also the details, to be meticulous, because it also includes the mold aspect.

1.Maintain the treatment of molten aluminum in the furnace.

Keep the furnace for slag removal and oxygen removal every week, and scrape off the alumina, but do not use slag remover.

2.Precautions for baking molds.

1) The grill should be made according to the specifications of the mold, so that the temperature can be evenly distributed when baking the mold.

2) The operator should wear a mask and do a good job of safety protection.

3) When using the grill, pay attention to ignition safety, and the flame should be easy to adjust. If there is oxygen leakage, it cannot be used.

3.Installation of thermometer rods.

The bottom of the thermometer rod should be in the same position as the water outlet, and certain requirements should be complied with during installation, and it should not be installed in violation of regulations.

4.Precautions are required for mold preparation and inspection before production.

1) Whether the air outlet of the air duct is blocked and whether the interval position is correct.

2) The distance between the air outlet and the bottom of the hole should be 5-10mm.

3) The spraying temperature is 200, and it cannot be applied to the side mold tire ring, which will produce bubbles.

4) The air cooler should not be oriented towards the mold, otherwise problems will occur.

Gravity casting mold is an indispensable part of the gravity casting process, the quality of gravity casting mold plays a decisive role in the castings produced by gravity casting process, since gravity casting mold is so important, then, in the process of producing gravity casting mold, what do we need to pay attention to? Let's let Huazhu mold take you to take a look.

As a more widely used process technology, gravity casting has a greater demand in many industries, and gravity casting molds are also very popular on the market. It should be noted that in the actual gravity casting production process, each link must be strictly controlled, once any link makes a mistake, it will cause the quality of the casting to be damaged or even scrapped directly, so it is also very necessary to understand the gravity casting mold production needs to pay attention to the place.

1.Preparation for pouring.

Before gravity casting, it is necessary to be prepared for pouring, which is a prerequisite to ensure the smooth operation of the entire process. Specific preparations include site cleaning for pouring and quality inspection of pouring ladles.

2.Pouring temperature.

For the factors to ensure the quality of castings, the pouring temperature is a very core part, and it also needs to be strictly controlled. Once the temperature control of the master is not good, it will directly affect the quality of the casting, and may also cause the gas to be unable to discharge smoothly.

3.Gravity casting molds.

Whether the quality and size of the gravity casting mold match the actual production needs of the casting is very critical, and it must be strictly inspected in advance. In addition, the correct operation method is also an important factor affecting the quality of castings, which requires strict training.

One of the points that affects the quality of gravity casting molds is the design. Why?

Because the gravity casting mold is almost the same, the point that affects the gravity casting mold is some small details, if these details are not done well, then even if the appearance is the same, but the quality of the castings produced is very different. For example, to find the weak point, which means to find the weak point of the casting that will be produced, then when designing the mold, it is necessary to avoid these weak points, and even make up for these weak points, so that they become strong points instead.

If you don't have many years of experience in gravity casting mold design, you can't do it well without the accumulation of experience in various casting mold design. Huazhu Huazhumj designers are experienced, you can search for it, find out!

The gravity casting machine is to cast the molten metal heated to a certain extent into the gravity casting mold through the gravity of the earth, and then process it to form a casting product. Since it is a molten metal that needs to be heated to cast, and molten metal like aluminum heating requires a high temperature of at least 660, in order to avoid safety accidents, the casting personnel of the gravity casting machine need to pay attention to the following points.

Kun * Tai tells you that the casting personnel should wear good work clothes, wear protective glasses, prepare the site for casting molten metal, and the casting channel should be unimpeded. Because once the molten metal or casting touches the human body, the staff will be burned, and once they encounter any flammable and explosive materials, it is very dangerous.

After the casting is completed, the casting personnel should also pay attention to cleaning the equipment in time, and also pay attention to the protection work when cleaning to avoid high temperature damage to personnel. Because of the high professionalism of the gravity casting machine, it is easy to leave many potential safety hazards if you are not careful, so the casting personnel should be strict with themselves for their own safety and try to avoid safety accidents.

First of all, we must pay attention to the safety of operators, but also pay attention to the timeliness and flexibility of operation, and finally pay attention to the protection and maintenance of machinery.
