Description

Technical Field

[0001] This utility model relates to the field of casting mold technology, and more specifically, to a casting mold for rapidly cooling aluminum alloy conductor castings. Background Technology

[0002] Aluminum alloy conductors are electrical conductors made of a mixture of aluminum and other alloying elements. They are modified electrical metal materials using aluminum alloys, nickel alloys, or copper-zinc-aluminum flexible wires. Due to their special alloy combination, aluminum alloy conductors have better electrical and mechanical properties, are durable, suitable for wiring, and have high cold plasticity. Aluminum alloy conductors are generally cast using casting molds.

[0003] A search revealed that utility model patent CN208322004U discloses a casting mold for aluminum alloy conductors, comprising a sprue sleeve, an upper right mold, a lower right mold, a first forming cavity, a lower left mold, a second forming cavity, a dividing mold, and an upper left mold. The upper mold has casting ports on both sides of its upper end face, with a sprue sleeve installed on the annular side of each port. The upper left mold is installed on the left side of the lower end face of the upper mold, and the lower left mold is installed on the lower end face of the upper left mold. The upper right mold is installed on the right side of the lower end face of the upper mold, and the lower right mold is installed on the lower end face of the upper right mold. A dividing mold is installed between the lower left and lower right molds. A second forming cavity is located between the lower left mold and the dividing mold, and a first forming cavity is located between the lower right mold and the dividing mold. This design solves the problem of low casting efficiency in existing aluminum alloy conductor casting molds. This patent has a reasonable structure, facilitates casting, and has high work efficiency and utilization. However, the aforementioned patent has the following shortcomings: the casting liquid in forming cavity one and forming cavity two needs to cool and solidify naturally, which takes a long time and affects the casting efficiency. To address this, we propose a rapid-cooling aluminum alloy conductor casting mold. Utility Model Content
