4: fasteners, check the fasteners are loose, damaged phenomenon, the approach is to look for the same size of the parts to be replaced. 5: binder components such as pressure plate, excellent strength glue, etc., unloading parts such as stripper plates, pneumatic roof materials. Check all parts of the relationship between time and maintenance parts for damage, repair the damaged part, pneumatic ejector check for air leaks, and to take measures to specific situations. Such as tracheal damage replacement. Several important parts of the mold to focus track testing: top out, the role of the guide member is to ensure that mold opening and closing the top of the movement and plastic parts, if any of these positions due to injuries and stuck, will lead to cut-off, it should be kept mold thimble, lubrication of the guide post (to choose the most suitable lubricant), and regularly check the thimble, guide posts and whether the deformation and surface damage, once discovered, to be replaced; after the completion of a production cycle, to work on the mold surface sports, professional guide member coated anti-rust oil, in particular, attention should be paid to the protection of plastic products processing with gear, rack mold and elastic strength of the spring bearing portion of the die, in order to ensure that it is always in top working condition; With Production lasted, cooling channels easily deposited scale, rust, mud and algae, so that the cooling flow channel cross-section becomes smaller, the cooling channel narrows instruments plastic products processing, greatly reducing the rate of heat exchange between the coolant and the mold, increase business daily hardware plastic products production and processing costs, so clean up should pay attention to the flow channel; hot runner mold in terms of maintenance for electronic communications plastic products processing, heating and control system helps prevent production faults, therefore particularly important.
