1. In the process of aluminum alloy profile extrusion mold trial and aluminum extrusion, the following aspects should be paid attention to:
A. Determination of the temperature of the mold temperature rod before extrusion of aluminum alloy profiles, whether it meets the requirements of extrusion temperature, whether there is a permeable core for heating (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 aluminum extrusion die must be aligned with the center position, so as to avoid the phenomenon of collapse and jamming.
C. For different aluminum alloy profile molds, appropriate extrusion speed should be selected to avoid poor discharge caused by too fast and too fast.
D. In the process of extrusion of aluminum alloy profiles, we should also pay attention to the quality of aluminum rods to avoid mold collapse caused by impurities in aluminum rods.
2. Aluminum extrusion mold modification is a very important link, but the first thing to consider is its strength, and the mold repair should be carried out on the basis of ensuring the strength of the aluminum extrusion mold. Welding is generally not used until the last degree, because welding has a significant impact on the life of the mold. In particular, the welding of the working belt is very easy to shorten the life. For the repair of the profile fast and slow, it is generally used to repair the slow place quickly instead of slowing the fast place. At this point, the burden on the mold structure can be reduced to a certain extent to ensure its life. 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 potting molds, special attention should be paid to the link of punching, especially in some screw holes or more fragile places, otherwise, it is easy to flush the mold.
4. The handling process of aluminum extrusion dies should be carried out carefully to avoid bumping into the working belt and other places. Before the mold is put into the warehouse, it must be cleaned, carefully and thoroughly inspected the mold for small cracks and damage.
5. For the finished mold, its process data must be effectively managed, such as the mold repair plan, processing details, extrusion process, etc. Because these can become replication objects for subsequent supplementary molds or similar molds, which can effectively improve the pass rate of molds.
Extrusion die life depends on the perfect link between design, manufacturing, use and subsequent maintenance. Through the effective integration of each link, it is believed that the mold life can be improved accordingly.
