What should we pay attention to in the maintenance of foam molds?

1. Try to use the standard material gun of the mold factory and use stainless steel round rods. Do not block the material gun hole due to rust of other materials or block the air plug hole due to rusty slag. The locking screw should also use stainless steel bolts and sliding teeth. Replace it as soon as possible afterwards to ensure that the mold can be locked every time it is opened and closed to prevent leakage during molding and flash. Foam mold

2. The mold is cured with hot steam and the foam is cooled with cold water. The outer surface of the mold will inevitably be covered with scale such as calcium carbonate, which affects the cold and heat exchange and molding quality of the mold. Reach the surface of the mold cavity, overhaul the mold and replace the airlock. This requires the mold to be descaled and maintained within about a week. Descaling generally involves placing the mold in a weakly acidic environment to soften the scale and then knocking it off. The material determines that the mold cannot be in a weakly acidic environment for a long time, and it is easy to corrode the surface of the cavity. Descaling is a big challenge for the maintenance of lost molds. The solution developed by Luoyang Liu's mold can easily remove mold scale without corroding the surface of the mold cavity. Check the water quality frequently to keep the mold water environment in a weakly alkaline environment, so that it is not easy to produce scale on the mold.
3. Since the foam also has a certain degree of corrosion and wear on the surface of the mold cavity, it is necessary to have a special covering mold on the surface of the mold, which is acid, alkali and high temperature resistant, and can ensure that the mold surface is smooth and easy to demold. It can also be used in combination with the mold. The material has good affinity, and the coating is not easy to fall off on the surface of the mold cavity. Luoyang Liu's mold uses a special Freon coating technology to cover the mold surface with a 0.02mm thick Freon film to meet the needs of the mold. Project performance requirements.
4. Handmade molds need to be manually disassembled and transported during use. Please handle with care during use to extend the service life as much as possible. Check the autoclave, pipelines, etc. before use, and some hidden dangers in the molding process can also be avoided.
