Four Steps Detailed injection mold maintenance

Any items require maintenance to prolong its service life, and now I will introduce the injection mold maintenance steps below.
    Responsible business should first understand the basic situation of the mold, as first deputy dies should give each card with biographical detail records, statistics of its use, care (lubrication, cleaning, rust) and damage, which can be found whereby parts, components have been damage, wear extent size to provide discovery and problem-solving information, and molding process parameters of the mold, the product of the materials used to shorten the mold test time and increase productivity.
    Processing enterprises should be under the injection molding machine, mold normal operation, the test performance of various molds and molded plastic parts last measured dimension, you can determine the current state of the mold through the information to find out the cavity, core cooling systems and sub-surface damage, such as where, according to information provided by the plastic parts, you can determine the status of the mold damage and repair measures.
    To die several important parts to focus track testing: top out, the role of the guide member is to ensure that the opening and closing movement of the mold and the top of the plastic parts, if any of these positions due to injuries and stuck, will lead to shutdown, it should be kept mold thimble, lubrication guide post (to choose the most suitable lubricant), and regularly check thimble, guide posts, etc. are deformed 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 should pay attention to the strength of the stretch with a gear rack mold bearing parts and springs mold protection, to ensure that it is always in top working condition; as production lasted cooling channels easily deposited scale, rust, silt and algae, so that the cooling passage section becomes smaller, the cooling channel narrows significantly reduce the rate of heat exchange between the coolant and the mold, increasing production costs, so clean-up of the flow channel attention should be paid; for hot runner mold, the maintenance of heating and control systems help prevent the production of faults, and therefore particularly important. Therefore, all deal with the end of each production cycle with a heater on the mold, rod-type heater, heated probe and thermocouple measurements with an ohmmeter, if damaged, must be replaced, and the mold resume comparison, make a record, so that timely detection of problems, take countermeasures.

    So do the last part of the mold surface is maintained, and the so-called surface is to prevent corrosion, and therefore, the choice of a suitable, high-quality, professional-rust oil is particularly important. When the mold production tasks, should be taken different ways, depending on the injection carefully remove residual injection, available copper, copper and professional mold cleaners remove residual mold injection molding and other sediments, and air dried. Disable wire, steel bars and other hard objects to clean up, so as not to scratch the surface. If rust corrosion caused by injection, to use a grinder polishing and spray on a professional anti-rust oil, and then the mold in a dry, cool, no dust at the store.
