Key Points for Injection Mold Maintenance
Injection mold maintenance is a comprehensive process encompassing cleaning, lubrication, rust prevention, inspection, temperature control, storage, and more. Through scientific and systematic maintenance, mold lifespan can be extended, product quality can be improved, and production costs can be reduced.
Here are several key points for maintaining precision plastic molds:
1. Cleaning and Drying
Prompt cleaning: After each production run, remove plastic residue, oil, and dust from the mold. Use specialized cleaning agents and soft brushes to avoid scratching the mold surface.
Keep dry: Thoroughly dry the mold after cleaning to prevent rust and corrosion caused by moisture retention.
Focus on key areas: Pay close attention to mold cavities, cores, guide posts, bushings, and other critical areas during cleaning.
2. Lubrication
Choose the right lubricant: Select a specialized mold lubricant to avoid contaminating the mold with general-purpose lubricants.
Lubricate moving parts: Regularly lubricate sliding parts such as guide posts, bushings, and ejector pins to reduce friction and extend service life.
3. Control the amount: Avoid excessive lubrication to prevent product contamination.
Rust Prevention
Use rust inhibitors: Regularly apply rust inhibitors or a thin layer of rust-preventing oil to the mold.
Store in a dry environment: Store the mold in a dry, ventilated environment to prevent moisture.
Focus on steel components: Pay particular attention to steel components, especially those prone to rust.
4. Regular Inspection
Visual inspection: Regularly inspect the mold for cracks, deformation, wear, and other defects.
Functional inspection: Verify that all functional components, such as ejector pins and guide posts, are working properly.
Cooling system inspection: Ensure the system is unobstructed to maintain effective mold cooling.
5. Storage
Dry and ventilated storage: Store the mold in a dry, ventilated, and dust-free environment.
Dust protection: Cover the mold with a dust cover to prevent dust accumulation.
Regular inspection: Periodically inspect stored molds to prevent damage.
