The maintenance of injection mold is very important. Be aware that any damage anywhere may cause shutdown. Under the normal operation of the mold, test various parameters of the mold to determine the existing status of the mold. If there is a problem, damage can be detected in the cavity, core, cooling system and parting surface. At the same time, it is also necessary to carry out key inspection on several important parts: ejection. The function of the guide part is to ensure the opening and closing movement of the mold and the ejection of the plastic parts. If there is damage and jamming in one part, it may be discontinued. Therefore, if there is any wrong wear or other problems, they should be found as soon as possible to avoid unnecessary occurrence.
So how to do a good job of maintenance? After completing a production cycle, the working surface, moving and guiding parts of the die shall be coated with professional anti rust oil. If there is protection for the bearing part of the rack mold and the elastic strength of the spring mold to ensure that it is always in working condition. These are very important. With the continuous production time, the cooling channel is easy to deposit scale, rust, sludge and algae, making the section of the cooling channel smaller and the cooling channel narrower. Therefore, attention should be paid to the cleaning of the channel to avoid the failure of the channel. Early discovery and early maintenance will enable the runner to play its due role.
There is a special problem here. For hot runner molds, the maintenance of heating and control system is helpful to prevent production failures, because it is very important. Therefore, after the end of each production cycle, the belt heater, bar heater, heating probe and thermocouple on the mold should be measured with an ohmmeter. If they are damaged, they should be replaced in time, compared with the mold resume, and recorded so that problems can be found in time and countermeasures can be taken. The history of the mold can help us avoid detours, which is right. Take precautions before they happen. If any problem is found, the remedy can be applied to the case.
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 focus is to prevent corrosion. Therefore, it is particularly important to select a suitable, high-quality and professional anti rust oil. Avoiding corrosion in time is the most important thing at present. After the production task of the mold is completed, the residual injection molding shall be carefully removed by different methods according to different injection molding. The residual injection molding and other deposits in the mold can be removed with copper rod, copper wire and professional mold cleaning agent, and then dried. Do not use tools such as iron wire to clean the inside of the mold, so as not to damage the internal surface and cause rust more easily.
