What issues should be paid attention to when maintaining mold accessories?
Nov 11,2025
Mold accessories are essential components in ensuring the smooth operation and precision of molds. Proper maintenance is critical to extending service life, reducing downtime, and improving production efficiency. Below are some key precautions for caring for mold accessories:
Maintenance Precautions:
Prevent Rust and Corrosion
Mold components such as ejector pins, guide pins, and wear plates should be kept dry and free from fingerprints, sweat, or impurities.
Apply anti-rust oil regularly, especially after cleaning or before long-term storage.
Regular Inspection
Check the wear and tear of sliding parts (e.g., slide cores, wear plates) to avoid abnormal friction.
Inspect guide pins, bushes, and lifters for scratches or deformation; replace immediately if tolerance exceeds limits.
Lubrication
Apply proper lubrication oil or grease on moving parts such as slides and lifters to ensure smooth movement and prevent early wear.
Replenish lubricant regularly during high-frequency production.
Cooling System Care
Regularly clean cooling channels, connectors, and baffles to prevent scaling or blockages.
Use clean coolant with appropriate concentration to ensure stable temperature control.
Storage and Protection
When molds or accessories are not in use, store them in a dry, ventilated environment.
Apply protective coatings or anti-rust treatment during holidays or long idle periods.
Why proper maintenance matters?
The service life of mold accessories directly affects mold performance and production stability. With proper care, components such as ejector pins and guide bushes can maintain precision for 5–8 years or more. Good maintenance not only reduces replacement frequency but also lowers production costs and ensures consistent product quality.
