3. In the application of mold accessories, the mold equipment is now covered, and the aluminum skin should be removed immediately to avoid crushing the abrasive tool.

In the application of abrasive tools, usually due to various reasons, there will be sagging and aluminum skin on the abrasive tools by hardware machinery and equipment. Especially the position of the guide rail slider. If the ropeway enters the aluminum skin, etc., because the clamping force of the aluminum die-casting machine is very large, the guide rail slider will collapse and be crushed. Therefore, when encountering such problems, be sure to remove the abrasive tool immediately, and search for the reason to repair the abrasive tool immediately. Otherwise, if the abrasive tool is damaged before overhauling, it will seriously endanger the service life of the abrasive tool.

4. Reduce the pouring temperature of lithium bromide solution as much as possible to increase the service life of the abrasive tool.

The pouring temperature of lithium bromide solution during aluminum die-casting production not only harms the quality of castings, but also harms the service life of die-casting mold parts. Generally, in aluminum die casting, the pouring temperature of lithium bromide solution is 630-720 degrees. For different parts, we should choose a lower pouring temperature as much as possible, which not only saves power and energy, but also can increase the die-casting mold zero. Use period of accessories. Because the higher the temperature of the lithium bromide solution, the greater the abrasion of the abrasive tool, the greater the range of temperature gradient transformation of the abrasive tool, the greater the thermal expansion and contraction, the greater the fatigue of the abrasive tool, and the easier it is to be damaged. Therefore, moderately reducing the pouring temperature of lithium bromide solution is beneficial to increase the use of plastic molds for die-casting mold parts.
