To improve the life of the mold, corresponding measures must be taken to improve these conditions. elarates on the main factors affecting the service life of the mold.
1. The impact of cemented carbide mold materials on mold life is a comprehensive reflection of the mold material type, chemical composition, organizational structure, hardness and metallurgical quality. Among them, the material type and hardness have the most significant impact. The type of mold material has a great impact on the life of the mold. Therefore, when selecting mold materials, the mold materials should be selected reasonably according to the batch size of the parts. The hardness of the workpiece also has a great influence on the mold life, but the higher the hardness, the longer the mold life is not.
2. The service life of the cemented carbide mold is related to its use conditions, the design and manufacturing process of the mold, the installation, use and maintenance of the mold. Therefore, in order to increase the service life of the mold, corresponding measures must be taken to improve these conditions.
It can be seen that the hardness of the cemented carbide mold must be determined according to the forming properties and failure modes, so that the hardness, strength, toughness, wear resistance, fatigue strength, etc. should achieve the required coordination for forming. The impact of metallurgical quality on mold life cannot be ignored, especially cemented carbide materials, which have many metallurgical defects, which are often the source of mold quenching cracking and early mold damage. Therefore, improving the metallurgical quality of materials is also an important aspect of improving mold life.
