Subsequent use and maintenance of the mold
1. In the process of mold testing and extrusion, the following aspects should be emphasized: A. Determine the temperature of the mold before extrusion, whether it meets the requirements of the extrusion temperature, and whether the heating has a core (the placement of the mold in the heating furnace is very important, and there should be a certain heating gap between the mold and the mold). B. The extrusion die must be aligned with the center position, so as to avoid the phenomenon of collapse and plugging. C. For different profile molds, the appropriate extrusion speed should be selected to avoid unsmooth discharging caused by too fast and too fast. D. In the process of extrusion, we should also pay attention to the quality of the aluminum rod to avoid the occurrence of mold damage caused by the impurities of the aluminum rod.
2. Mold repair is a very important link, but the first thing to consider in mold repair is its strength, and the mold should be repaired on the basis of ensuring the strength of the mold. Welding is generally not used until the final level, because welding has a significant impact on the life of the mold. In particular, the welding of the working belt can easily shorten the service life. For the fast and slow repair of the profile, it is generally used to repair the slow place faster than to slow the fast place. So far, the burden on the mold structure can be reduced, and its life can be guaranteed to a certain extent. Of course, improving the level of mold repair and reducing the number of mold trials is also one of the ways to improve the service life of the mold.
3. In the process of mold making, special attention should be paid to the process of taking punching materials, especially in some screw holes or fragile places, otherwise, it is easy to punch the mold.
4. The handling process of the mold should be carried out cautiously to avoid bumping into the working belt and other places. Before the mold is put into the warehouse, it is important to clean it, carefully and thoroughly inspect the mold to see if there are any small cracks and breakages.
5. For the mold that has been produced, it is necessary to effectively manage its process data, such as the mold repair plan, processing details, extrusion process, etc. Because these can be used as the replication objects of subsequent supplementary molds or similar molds, this can effectively improve the pass rate of molds.
The improvement of the life of the extrusion die depends on the perfect link between the design, manufacturing, use and subsequent maintenance processes. Relying on a single link can not effectively achieve the goal, through the effective integration of each link, I believe that the mold life can be improved accordingly.
