Injection plate mould maintenance notice _ injection sign _ mold maintenance

Injection plate mold maintenance matters needing attention in the use of injection molding sign mold need to be in the process of long-term care and maintenance, to extend the service life of mould, effectively prevent sign products surface defects and other problems. Mold maintenance is more important than repair, mold repair, the more the shorter its life. And the better the mold maintenance, its service life is longer. Next to introduce the injection plate mold maintenance need to pay attention to what matters: a. First of all should be equipped with injection molding sign mold record card, detailed, statistics of its use, care, lubrication, cleaning, rust, and damage. For mould maintenance regularly, can be found in time which parts, components, damage, wear size. Record the products molding process parameters, the materials used, to shorten the test time, improve production efficiency. 2. Should be in all kinds of mold injection molding machine working normally test performance, and will be the final molding injection plate size measurement. Through these information can determine the existing state of mould, find out the cavity and core, cooling system and parting surface damage. According to the injection plate products surface quality, can judge the mold damage status and maintenance measures. 3. Is important to mold parts for tracking detection: thimble, guide pin, guide sleeve parts role is to ensure that the plastic mold opening and closing movement and sign out smoothly, will lead to stop production if any of these parts for damage. Should maintain frequent lubrication mould thimble, guide pin, and regularly check all moving parts are in the distortion and surface damage, once found to timely replacement. After completing a production cycle, do you want to work to the mold surface, sports, guiding parts coated with anti-rust oil. Attention should be paid for with gear and bearing parts and spring rack mould stretch strength of protection, to ensure that components are always in the best working state. With production time increasing, the cooling way easy to deposit scale, rust, sludge and algae besmirch, narrow the cooling groove section size, cooling channel, greatly reduced the heat exchange between the coolant and the mold rate, thus increasing the cost of production, so we should pay attention to clean up on passage. Heating and control system for hot runner mold maintenance helps prevent production failure. So each end of the production cycle in response to die band heater, heater, heating probe as well as with the ohmmeter measuring thermocouple. If there is damage to change in time, and comparing with mould resume, completes promptly replace records, so as to make similar problems in the process, can effectively the adoption of countermeasures. Four. The last part is to do the mold surface maintenance, surface maintenance mainly to prevent rust, so choose a suitable anti-rust oil, high quality, professional becomes more and more important. After the mold to complete production tasks, should be based on different injection sign products adopt effective methods to remove the residual resin. Available copper rod, copper wire and professional mold cleaner to remove residual plastic and other sediments in the mould, then dry processing. Disable clear iron wire, steel and other hard objects, in order to avoid scratch mould surface. If corrosive injection caused by rust point, to use grinding machine grinding and polishing, and professional rust-proof oil spray, and then put the mould in a dry, cool storage, no dust.
