The maintenance of injection mold is very important. Note that damage anywhere can cause a shutdown. Under the normal operation of the die, the performance parameters of the die are tested to determine the current status of the die. Above,
If problems occur, damage can be detected in cavities, cores, cooling systems, and parting surfaces. At the same time, there are several important parts should be tested: demoulding, the role of the guide rail part is to ensure the opening and closing movement of the mold and demoulding plastic parts, if there are parts damaged and stuck, it is likely to stop production. Therefore, if there is no wear or other problems, they should be found early to avoid unnecessary occurrence.
Then how to do the maintenance work well? After completing a production cycle, the working surface of mold, movement and guide rail should be coated with professional antirust oil. If there is elastic strength protection for the bearing parts of rack mould and spring mould, it will always be in the best working condition. These are all important. With the extension of continuous production time, the cooling channel is prone to scale, rust, sludge, algae and other deposits, making the cooling channel section smaller and the cooling channel narrower. Therefore, pay attention to cleaning the channel to avoid channel failure. Early detection and early maintenance, runner can play its due role.
There is a special problem here. For hot runner mold, the maintenance of heating and control system is helpful to prevent production failure, because this is very important. Therefore, at the end of each production cycle, the belt heater, rod heater, heating probe and thermocouple on the mould shall be measured with ohmmeter. If there is any damage, it should be replaced in time, compared with the mold recovery, and make records, so as to find problems in time and take countermeasures. The history of molds can help us avoid detours. That's right. If there is a problem, you can solve it.
There is no doubt that the surface maintenance of the mold can not be ignored, it directly affects the surface quality of the product, and the key is to prevent rust. Therefore, it is particularly important to choose the appropriate, high-quality and professional antirust oil. Timely prevention of corrosion is the most important thing at present. When the mold completes the production task, different methods should be adopted according to different injection methods, carefully remove the residual injection in the mold, use copper bar, copper wire and professional mold cleaner to remove the residual injection and other deposits in the mold, and then dry. Do not use wire and other tools to clean the inside of the mold, so as to avoid internal surface damage and easy to cause rust.
The above is a detailed introduction of the importance of Shandong mold to the maintenance of injection mold. For more information, please click http://www.jnhjgs.cn
