How to define the maintenance time
In order to ensure that the injection molding machine can work continuously and stably for a long time, one thing we need to know is that it is very important and necessary to maintain the equipment regularly. Because this will directly affect the service life of the injection molding machine and the probability of failure during use. However, when maintaining the injection molding machine, we should remind you that the maintenance of the equipment can be defined by time.
1、 Weekly maintenance and inspection items of injection molding machine:
1. Check and tighten the connecting bolts of the injection molding machine, such as elbow connection and fastening bolts of moving parts, mold fastening and connecting bolts or screws of moving parts in the structure, fixed locking screws of limit switches, etc.
2. Check the cooling pipeline and oil circuit of each system in the cooling device of hydraulic oil and lubricating oil, check whether there is oil leakage and water, and properly tighten or replace the sealing gasket if necessary.
3. Carefully check the change of grease in each lubricating point and oil pipeline, whether there is water in the oil, whether there is metal powder or other sundries in the oil, and replace the lubricating oil or filter it if necessary.
2、 Monthly maintenance and inspection items of injection molding machine:
1. Check the quality of hydraulic oil. If it is found that the oil contains impurities, the oil is insufficient or contains water, it shall be handled in time and the insufficient hydraulic oil shall be added.
2. Check whether the circuit of each point indicator is loose.
3. Check the ventilation filter on the electric cabinet, remove dirt, and remove it for cleaning if necessary.
4. Clean the hydraulic oil filter screen.
5. Clean each movable surface (such as pull rod, sliding guide rail surface of injection base, etc.), and then re apply new lubricating oil.
3、 Annual maintenance and inspection items of injection molding machine:
1. Check the quality of hydraulic oil. Generally, it is required to replace the hydraulic oil for injection molding machine once every 12-18 months. When the new equipment is used, the hydraulic oil shall be discharged from the hydraulic system of injection molding machine after 3 months of use, and each control valve, pipeline and oil tank in the hydraulic system shall be cleaned once (because the worn iron powder The unclean sundries in the pipeline (including mixed into the oil quality) filter the hydraulic oil and refill it into the oil tank.
2. Correct the temperature difference error between the display of thermocouple temperature measuring instrument and the measured temperature measuring point with thermometer, remove the dirt at the contact point of hot couple, and correct the correct working temperature measuring position of thermocouple.
3. Check the firmness of all wire connection points in the control box, check whether the rubber insulation layer of the line is aging, prevent electric leakage, and replace the line wire if necessary.
4. Check the wear condition of gear tooth surface and the quality of lubricating oil in reduction box, and make records.
5. Check the wear condition of screw and barrel, repair slight wear and scratch, repair in case of serious wear, make records and put forward replacement plan.
For the injection molding machine, it will not only be easier to maintain it according to time, but also have a very excellent effect on the equipment. These are the experience of the injection molding machine manufacturers. Therefore, we share it with you here and hope you can protect your equipment well.
