The conventional maintenance is to die for damaged, carries on the inspection, cleaning and lubrication, the main items are as follows.
  1.using the pre inspection. Injection mold before use, to check whether the document control process, the mold by the use of specifications, models of unity and process file. Whether the use of the inspection of the equipment to adapt with the mold, the mold is intact. The operator should understand in detail the performance, structure, function of the die and be familiar with the principle, operation method.
  2.using the process of inspection. Operation site must be clean, tools should be placed neatly, mould should be no foreign body, roads should be clear. Injection mold in the use process, must abide by the rules, prevent clutter, chaos hit, touch. The first few parts of mold production, according to the pattern of careful inspection, qualified rear can production. At work, at any time to check the working condition of mould, abnormal phenomena must be maintained at any time. Pay attention to lubrication of mould, lubricate moving parts to mold the timing.
  3.after the check. After use, according to the operating rules will die down from the injection molding machine, forbid chaos, chaos and unloading, so as not to damage the mould. The mould lifting should be safe, light up, slow down, after the demolition of the mold, to wipe clean, antiseptic and oiling. Technology status check mold after use, so as to restore to the normal working state, and then integrated into the specified storage location.
  4.cooling waterway maintenance. In the injection mold, cooling channel is unavoidable, and cooling water quality, is very important for the quality of plastic parts. Cooling water channel in the surface sediment incrustation, corrosion, mud and algae, they clog waterways, and greatly reduce the exchange, and die of heat between therefore, timely inspection and maintenance is very necessary. Jam check. Is blocked, by measuring the velocity of flow of cooling water to understand, cooling water through the die pressure drop size, congestion can reflect the channel. Dredge jams after. Cooling channels blocked, must be clear in time, inconvenience due to injection mold open, so it can only make no disassembly and cleaning. When dredging, available cleaning agents, cleaning squeeze into cooling water channel, with strong pressure, dirt accumulation of substance in the scouring force and chemical corrosion from the channel wall stripping down, so as to achieve the purpose of dredging.
