Proper application and protection of the precision die-casting mold

Correct application of a precision die casting mold

Reduce the cold and heat of the mold as far as possible, produce continuously as much as possible, and prohibit high-speed pressure shooting under the condition of cold mold. In the process of precision die-casting, the die-casting mold has been changing from 160 degrees to 350 degrees, and the hot and cold contraction recovery mold is hot and hot, which leads to the continuous heat rise and cold contraction of the mold. Therefore, in the production of precision die casting, it should be as continuous as possible, reduce the number of cold and hot molds, and extend the mold life.

Reduce the pressure shot speed and specific pressure to reduce the impact of the mold. In the production of precision die casting, the concave and convex of the pressure casting speed not only affects the filling speed and the internal pouring speed of the precision die casting but also affects the pressure firing speed, which is high, and the impact peak will increase. Therefore, the erosion of the mold will be aggravated, the impact peak will be increased, the impact of the mold will be increased, and the life of the mold will be greatly reduced.

When adjusting the precision die-casting process, the master will reduce the pressure shot speed as far as possible while ensuring product quality. Now, the advanced precision die casting machine is equipped with pressure shooting braking equipment, which will reduce the peak impact of the mold, which is very beneficial to the life of the mold.

In the process of mold use, the front and aluminum skin should be cleaned in time to avoid squeezing the mold. Especially the slider part, because the precision die casting machine mold force is very large, if the slide is squeezed into the aluminum skin, the slide will collapse and be broken. When encountering such problems, clean the mold in time, find out the cause of the problem, and repair the mold in time. If the mold is damaged, it will seriously affect its life. Reduce the aluminum liquid pouring temperature and further improve the service life of the mold. The pouring temperature of aluminum liquid in precision die-casting production not only affects the quality of casting but also affects the service life of precision old-bed casting plants. In general, when casting the essence body, the temperature of the aluminum full pouring ocean is 630 degrees to 720 degrees. For different parts, the casting division will choose the pouring temperature as low as possible, which can not only save power but also prolong the service life of precision die-casting molds.

Protection method of precision die-casting mold

Strengthen the protection of the mold through regular maintenance, recharge, and reduce the stress in the mold cavity. Precision die casting dies are always in high pressure, high speed, and high temperature continuous production. The use of conditions is evil, and in the process of use, broken or hand diseases are a risk, so strengthening the mold and quality wood holes is very important to ensure the reliability of the mold in precision die casting when necessary operations are performed.
