What are the daily maintenance tasks of HXM servo injection molding machine?

1. Maintenance of the hydraulic system of the injection molding machine
The oil level of the hydraulic oil tank of the HXM servo injection molding machine needs to be checked daily to ensure that the oil level is above the center line of the level gauge to avoid idling of the oil pump or pressure fluctuations due to insufficient oil. Hydraulic oil oxidation is the main cause of system contamination. When the oil is milky white or turbid, the same type of hydraulic oil needs to be replaced. Oil products with strong oxidation resistance and wear resistance can be selected. The oil temperature needs to be controlled within the standard range. Clean the oil suction filter regularly to prevent impurities from clogging the oil pump inlet. Disassemble the cooler and remove scale every year to ensure heat dissipation efficiency.

2. Maintenance of the lubrication system
Check the lubrication status of the machine hinge, guide rod, sliding foot and other parts to ensure that the lubricating oil flow covers the surface of all moving parts. Regularly check whether the lubrication pipeline is damaged or blocked, and observe the grease flow in the transparent oil pipe. If poor lubrication is found, the machine must be stopped immediately to check the oil pump pressure or the state of the distribution valve to prevent the mechanical parts from failing due to lack of oil.

3. Maintenance of mechanical parts
Before stopping, the residual plastic in the barrel (especially PET and other easily decomposed materials) must be drained to prevent carbonization and adhesion. Disassemble the screw every six months to check the wear of the parts, focus on cleaning the carbon deposits on the check ring and test the sealing. It is recommended to control the back pressure to ≤10MPa to reduce the shear loss of the screw. If processing easily corrosive materials such as PVC or POM, PP/PE plastics must be used for cleaning to prevent the residue from corroding the inner wall of the barrel.
