How to conduct effective maintenance of plastic injection mould?
1, and processing enterprise first should to each Deputy mold equipped with curriculum vitae card, detailed recorded, and statistics its using, and nursing (lubrication, and cleaning, and rust) and the damaged situation, accordingly can found which parts, and component has damaged, wear degree size, to provides found and solution problem of information information, and the mold of forming technology parameter, and products by with material, to shortened mold of test time, improve production efficiency.
2, and processing enterprise should in injection machine, and mold normal running situation Xia, test mold various performance, and will last forming of plastic pieces size measurement out, through these information can determines mold of existing State, find type cavity, and type core, and cooling system and points type surface, of damaged where, according to plastic pieces provides of information, to judgment mold of damaged state and maintenance measures.
3, and to on mold several important parts for focus track detection: top out, and oriented parts of role is ensure mold opening movement and the plastic pieces top out, if which any parts due to injury and card live, will led to cut-off, so should often keep mold thimble, and guide column of lubrication (to selection most for of lubricant), and regularly check thimble, and guide column, is occurred deformation and the surface injury, Once found, to timely replaced; completed a production cycle zhihou, to on mold work surface, and movement, and oriented parts James review professional of antirust oil, especially should attention on with gear, and tooth article mold bearing parts and spring mold of stretch strength of protection, to ensure its always is best work State; as production time continued, cooling road easy deposition scale, and rust, and mud and the algae,Make the cooling flow cross section smaller, cooling channel narrower, reduces the coolant between the mold and heat exchange rate, increasing production costs, so convection road cleanup should pay attention to; for hot runner mold, and maintenance of heating and control systems to prevent failures occur, hence is particularly important.Therefore, should die after the end of each production cycle with bar heaters, heaters, heating probes and thermocouples, measured with an ohmmeter, if damaged, replace, and compare to mold your resume, make a record in order to timely identify problems, responses.
4, pay attention to the mold surface maintenance, it directly affects surface quality, focused on preventing corrosion, so choose a suitable, high quality, professional rust preventive oil is even more important. When the mold after the production is completed, different methods depending on the injection should be carefully cleared the remaining molding, available copper rod, copper wire, and a professional mold cleaner to clear residual injection and other sediment from the mold, and then air dry. Disabling iron wire, steel bars and other hard things clean, so as not to scratch the surface. If there is rust and corrosion caused by injection points, to use a grinding machine for grinding and polishing, and sprayed the professional rust preventive oil, and place mold in dry, cool, dust-free storage.
