1. Daily regular inspection

 

Check and adjust all safety facilities every day, and ensure that all safety facilities are normal before using and operating the machine; Check the oil quantity in the lubricating oil tank and add new oil of the same brand; Check the oil level on the hydraulic oil tank. If the oil level drops below the centerline of the liquid level gauge, add hydraulic oil above the centerline, and add new oil of the same brand; After the first 1000 hours of operation, the oil suction filter and hydraulic oil shall be replaced or cleaned, and the oil tank shall be cleaned; When running for 5000 hours or at most one year, it is necessary to replace or clean the air filter and hydraulic oil. Note that the old and new hydraulic oil cannot be mixed; When operating for 20000 hours or at most 5 years, check and replace the sealing ring and wear ring of the hydraulic cylinder, and replace the high-pressure hose; Replace the controller (host) battery every 3 years; Replace the battery on the operation panel every 5 years.

 

2. Pay attention to lubrication

 

During the use of the injection molding machine, it is necessary to regularly observe whether the lubrication points of the injection molding machine are in normal working conditions. Note that the time for each lubrication must be sufficient to ensure that each lubrication point of the whole lubrication system is well lubricated. The lubrication modulus (interval time) of the machine and the time of each lubrication are realized through the reasonable setting of computer parameters. Regularly observe the working condition of the lubrication system and keep the lubricating oil in the oil tank at a reasonable level. If poor lubrication is found, it shall be lubricated in time, and the lubrication condition of each lubrication point shall be checked to ensure good lubrication of the machine.

 

3. Check the air filter

 

The air filter of the oil tank is used to breathe in the oil tank and prevent external dirt such as dust from entering the oil tank. Therefore, it is a very important component and needs regular maintenance. The air filter is installed on the top of the oil tank. To clean, loosen the cover, replace the air filter element, and then tighten the cover again. Pay attention that the cover must be screwed tightly, otherwise oil will spill.
