Analysis of the reasons for the scrapping of die-casting mold manufacturing

(Summary description)Avoid sharp corners as much as possible in mold design, and the positions of holes and grooves should be arranged reasonably.

1. Mold design
Avoid sharp corners as much as possible in mold design, and the positions of holes and grooves should be arranged reasonably.
2. Selection of die steel
The selection of die steel must complete the use of heat treatment to eliminate carbide segregation, refine carbide, and uniform structure.

Die casting customization material

3. Cooling and lubrication
Cooling and lubrication of the mold In order to reduce the heat load of the mold and avoid the mold temperature from being too high, it is usually forced to cool the mold during the intermittent operation, which will cause thermal fatigue cracks due to the periodic heating and cooling of the mold . Therefore, the mold should be cooled slowly after use, otherwise thermal stress will occur, which will cause cracking and failure of the mold.
4. Die casting and maintenance
The mold should be fully preheated before die casting. If the preheating temperature is too high, the temperature of the mold will be high during use, the strength will decrease, and plastic deformation will easily occur, causing the surface of the mold to collapse; Initiation of cracks.
