What are the key measures to extend the service life of differential pressure casting molds for wheel hubs?

1、 Daily maintenance
The daily maintenance of differential pressure casting molds for wheel hubs is the foundation for ensuring their long-term stable operation. Cleaning work is essential. After each use, the mold should be thoroughly cleaned immediately to remove surface oil stains, impurities, and rust. This not only helps to keep the mold clean and smooth, but also prevents these residues from causing further corrosion and damage to the mold. During the cleaning process, professional mold cleaning agents should be used and the correct cleaning steps should be followed to avoid using cleaning agents or tools that can damage the mold.
Lubrication treatment is also an important part of daily maintenance. Molds will experience frequent friction and wear during use, and regular lubrication can effectively reduce these wear and extend the service life of the mold. During the lubrication process, suitable lubricants should be selected based on the usage environment and conditions of the mold, and appropriate lubrication points and cycles should be determined. At the same time, it is important to ensure the quality and stability of the lubricant and avoid using expired or deteriorated lubricants.

2、 Regular inspection and maintenance
Regular inspection and maintenance of differential pressure casting molds for wheel hubs are key to ensuring their long-term stable operation. Conduct a comprehensive inspection at least once every six months, including the wear, deformation, and damage such as cracks of the mold. During the inspection process, professional testing tools and methods should be used to ensure the accuracy and reliability of the inspection results.
For any wear or damage found, timely repair or replacement should be carried out. When repairing, appropriate repair methods and materials should be selected based on the degree and location of damage to the mold. For example, for minor wear, grinding or polishing methods can be used for treatment; For severe damage, welding or replacement of new components is required. At the same time, for vulnerable parts such as top rods and cores, careful inspection should also be carried out. If there are bends, cracks, etc., they should be replaced in a timely manner to ensure the accuracy and stability of the mold.
During the maintenance process, attention should also be paid to checking and tightening the fasteners of the mold. Fasteners such as screws and nuts may loosen during use, causing the mold to detach or shift during use. Therefore, the condition of these fasteners should be checked regularly and tightened using professional tools.

3、 Professional maintenance measures
In addition to daily maintenance and regular inspection and repair, some professional maintenance measures need to be taken for the differential pressure casting mold of the wheel hub to extend its service life. Annealing treatment is an important professional maintenance measure. Molds will generate thermal stress during use, which can cause cracking or deformation of the mold. Regularly annealing the mold can effectively reduce these thermal stresses and improve the strength and stability of the mold.
The maintenance of the cooling system is also one of the professional maintenance measures. Molds generate a large amount of heat during use, and if the cooling system does not work properly, it can cause the mold to overheat and be damaged. Regularly check whether the cooling water pipes and joints are leaking, and ensure that the quality and flow rate of the cooling water meet the requirements. It is also possible to consider using mold cooling water to further extend the service life of the mold.
Cleaning the parting surface is also one of the professional maintenance measures. The parting surface is an important component of the mold, and its state directly affects the accuracy and stability of the mold. Regularly clean the burrs and dirt on the mold parting surface to prevent the mold parting surface from collapsing and running aluminum. During the cleaning process, professional cleaning tools and methods should be used to avoid damage to the mold. During shift handover, the parting surface of the mold should be thoroughly cleaned with kerosene to ensure its cleanliness and smoothness.
