Maintenance of engineering plastics processing mainly includes the following aspects:
Regular cleaning and maintenance of molds: Engineering plastic molds are prone to accumulate dirt and impurities during use, which affects the service life and processing quality of the molds. It is recommended to use professional detergents, mix the detergent with clean water in a scientific proportion, soak the mold in the mixed solution, ensure that the solution fully covers the mold, let it stand for about five minutes, then thoroughly clean and apply protective agent to extend its service life.
Maintenance of hydraulic system: The hydraulic system is the core part of the injection molding machine and requires regular inspection and maintenance. Check and tighten each connecting bolt every week, check the quality of hydraulic oil and lubricating oil, and replace or filter if necessary. Check the hydraulic oil filter every month, clean the hydraulic oil filter, clean each active surface and reapply new lubricating oil. The hydraulic oil needs to be replaced every year, and the hydraulic system needs to be fully cleaned and maintained.
Maintenance of electronic control system: The electronic control system includes parts such as the electronic control box and wire connection points. The ventilation filter on the electric control box should be checked monthly to remove dirt and remove and clean it if necessary. The firmness of the wire connection point should be checked every year, and the rubber insulation layer of the line should be checked for aging. If necessary, the line should be replaced.
Maintenance of mechanical transmission system: The mechanical transmission reduction system should be checked every year, such as the cleaning and wear of the bearings, and the bearings should be replaced if necessary. Check the wear of the gear tooth surface and the quality of the lubricating oil in the reduction box, and record the relevant conditions.
Maintenance of lubrication system: The lubrication system includes the lubrication tank and lubrication points. The sediment inside the lubrication tank should be cleaned every month and replaced with new lubricating oil. The lubrication system should be fully inspected and maintained every year.
Safety test and daily inspection: Safety test should be paid attention to in daily operation, and abnormal safety test should be carried out on the mechanical safety lock and front and rear door limit switches of the injection molding machine. Check whether the operation of each lubrication block and ejector of the mold is normal every week, and report any abnormality immediately.
Through the above maintenance measures, the service life of engineering plastic processing equipment can be effectively extended, and the processing efficiency and quality can be improved.
