Maintenance of injection molding machine hydraulic system and cylinder

After studying the structural characteristics of the cylinder of the hydraulic system of the injection molding machine, we combined our own practical experience with a lot of theoretical analysis, according to the structural characteristics of the cylinder of the hydraulic system of the injection molding machine, we formulated the maintenance countermeasures of the hydraulic system and the cylinder. In the process of analyzing the maintenance and maintenance plan of the hydraulic system cylinder of the injection molding machine, the maintenance and maintenance of the hydraulic system cylinder of the injection molding machine we formulated is mainly for the common faults of the hydraulic system and cylinder of the injection molding machine.

1. In order to ensure that the hydraulic cylinder of injection molding machine will not leak from the piston rod of the hydraulic cylinder and the hydraulic transmission joint in the daily use process,therefore, in the daily use of the cylinder of the hydraulic system of the injection molding machine, we can avoid leakage accidents by regular and regular inspection of the joint parts of each system of the hydraulic system of the injection molding machine. Once in the process of checking the hydraulic system of the injection molding machine, it is found that the leakage phenomenon of the hydraulic system of the injection molding machine must be repaired in time, and the leakage oil should be cleaned in time.

• When installing the pipeline, make sure to clean and smooth the flange face and thread. When fixing the screw, pay attention to even force.

• Control the working temperature of the injection molding machine hydraulic system to ensure that the working temperature does not exceed 55℃. Once the phenomenon of system temperature rise, it is necessary to cool the system by cold water cooling method.

• In the process of using the injection molding machine, the oil level height of the pressure oil, the oil pump pressure and the cleaning degree of the pressure oil should be checked frequently. In wet weather, the concentration of pressure oil must be checked daily, and the water pipe should be checked frequently to avoid water mixing into the pressure oil and blocking the oil filter. Check the fuel tank regularly to keep it clean and prevent debris from falling in. When the oil level is not high enough, pressure oil should be added in time. For the lubrication of each moving part, each stroke switch and each oil pipe, joint part of the oil leakage, should be routinely checked once a week.

• The hydraulic oil should be replaced in time in strict accordance with the requirements of the operation rules of the injection molding machine (generally one to two years to replace once depending on the working situation), and the oil tank and oil filter should be cleaned to prevent the blockage of the oil circuit and the poor operation of the equipment.
