Description

Technical Field

[0001] This utility model relates to the field of feeding technology, specifically a feeding device that uses a screw for quantitative feeding. Background Technology

[0002] Magnesium alloy die casting is divided into two methods: hot chamber die casting and cold chamber die casting. Hot chamber die casting involves directly injecting molten metal from the crucible into the die casting machine. Cold chamber die casting involves first removing the molten metal from the crucible and then pouring it into the die casting machine. Because magnesium alloys are highly susceptible to oxidation and ignition, both hot and cold chamber die casting require the use of special nickel-free alloy steel crucibles, with SF6 or other protective gases added to prevent oxidation and ignition. Furthermore, since each crucible contains a relatively large amount of molten magnesium, insufficient molten magnesium will cause a significant drop in temperature with each addition of magnesium ingots, potentially disrupting production.

[0003] Existing methods all use large-volume crucibles to keep large amounts of molten magnesium at high temperatures, which consumes a lot of energy, has high operating costs, takes a long time to melt the bars, and the melting efficiency needs to be improved. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are:
