maintenance
Ι. Description
In order to increase work efficiency, it is possible to increase the running time of the machine, that is, it may be close to 24 hours of operation a day, if it is calculated as a month of operation, it will accumulate to 600 operating hours per month, so that a year will be 7200 hours, then it will be 4 times longer operation time compared with the general machine tool, so in order to extend the service life of the machine, the maintenance of the injection machine must be more important than the general industrial machinery.
II.. Repairs and Inspections
Pre-operation inspection (daily maintenance)
(1) Check the oil pressure volume to determine whether the oil quantity exceeds the minimum limit of the oil gauge and is lower than the maximum limit.
(2) Temperature switch and check to determine whether the electric heating device on the dryer, material tube and mold is normal.
(3) Check the emergency stop switch button.
(4) Inspection of low-pressure mold closing device to ensure that the low-pressure mold closing device is good.
(5) Inspection of cooling water to ensure that there is no water in the cooling water pipeline system and whether the water is sufficient to maintain the normal cooling effect.
(6) Check whether the temperature, pressure, speed, time, distance, etc. set by other conditions are correct.
(7) Check whether the operation is normal, and adjust and fix it when necessary, especially when the mold is replaced.
