In the long-term use of injection mold, in order to prevent and maintain to avoid mold wear, the following aspects can be carried out:
1. Regular cleaning and maintenance
Regular cleaning of molds: Injection molds will have residual plastic and other impurities during use, and these residues will accelerate the wear of the mold. Therefore, regular cleaning of the mold surface to ensure that there is no residue attached is an important measure to prevent wear.
Lubrication and rust prevention: Regular lubrication of the sliding parts of the mold such as guide pillars and push rods to reduce friction and wear. At the same time, when the mold is out of use, anti-rust oil or mold release agent should be sprayed to prevent rust and corrosion.
2. Reasonable use and operation
Control injection molding process parameters: Unreasonable injection molding process parameters such as too fast injection speed and too long holding time will increase mold wear. Therefore, the process parameters should be optimized to ensure that the flow rate, pressure and temperature parameters during the injection molding process are controlled within a reasonable range.
Avoid overload use: When using the mold, operate it in accordance with the design specifications and operating procedures to avoid overload use or incorrect operation that may cause mold damage.
3. Regular inspection and repair
Regular inspection of molds: Regularly conduct a comprehensive inspection of the mold, including appearance, size, electrical system, etc., and deal with problems in a timely manner. This helps prevent potential failures and extend the service life of the mold.
Timely repair of damage: The mold may be damaged or worn due to cracks, burrs, etc. during use. If these problems are not handled in time, they will accelerate the wear of the mold. Therefore, once damage or wear is found, it should be repaired or replaced in time.
4. Proper storage and maintenance
Reasonable storage of molds: Unused molds should be properly stored to avoid moisture, direct sunlight and other adverse environmental effects. At the same time, attention should be paid to prevent collisions and damage between molds.
Establish mold files: Set up a mold library, assign a dedicated person to manage it, and establish mold files.
In summary, during the long-term use of Injection mold, regular cleaning and maintenance, reasonable use and operation, regular inspection and repair, and proper storage and maintenance can effectively prevent and maintain mold wear and extend the service life of the mold.
