[0013] Please see Figure 1 and Figure 2This utility model provides an aluminum alloy mechanism box casting mold, including a bottom mold 101, a first half mold 102, a second half mold 103, and a sand core 104. The first half mold 102 is disposed at the upper end of the bottom mold 101 and is adapted to the bottom mold 101. The second half mold 103 is disposed at the upper end of the bottom mold 101 and is adapted to the bottom mold 101. The first half mold 102 and the second half mold 103 are adapted to each other, and the bottom mold 101, the first half mold 102, and the second half mold 103 enclose a cavity. The sand core 104 is embedded in the cavity and is adapted to the bottom mold 101, the first half mold 102, and the second half mold 103 respectively.

[0014] In this embodiment, the aluminum alloy mechanism box casting mold is a two-part mold, consisting of the first half mold 102, the second half mold 103, and the bottom mold 101. The boss of the casting 100 is designed as a curved parting, with a part of the boss being brought out by the bottom mold 101 and the rest being brought out by the first half mold 102 and the second half mold 103. The aluminum alloy mechanism box casting mold produces products with dense structure, high dimensional accuracy, and good surface roughness, while significantly improving the production efficiency and product qualification rate.

[0015] The aluminum alloy mechanism box casting mold combines the advantages of a two-part mold structure with aluminum alloy material. Aluminum alloy has good thermal conductivity and fast cooling speed, allowing casting 100 to solidify quickly, shortening the production cycle. The two-part mold structure is simple, and the opening and closing action is efficient, reducing operational complexity and failure rate. The combination of aluminum alloy and two-part mold can produce casting 100 with high dimensional accuracy and good surface finish, reducing the need for secondary processing. Aluminum alloy has low density, making casting 100 lightweight while maintaining high strength and good mechanical properties. It has high strength, high toughness, and good corrosion resistance. The aluminum alloy mold has a long service life and can withstand a large number of production cycles, reducing the frequency of mold replacement. Furthermore, due to the high precision of casting 100, subsequent processing steps are reduced, further reducing the production cost of casting 100.

[0016] Furthermore, the sand core 104 is made of an aluminum alloy core box.

[0017] In this embodiment, the aluminum alloy core box has high dimensional accuracy and surface roughness, which can ensure the high precision and high quality of the sand core 104. The sand core 104 hardens quickly, has high production efficiency, and is suitable for mass production. At the same time, the aluminum alloy core box has a long service life, reducing the replacement frequency and further improving production efficiency. Using the aluminum alloy core box to prepare the sand core 104 can significantly improve production efficiency, casting quality, and process flexibility, while reducing production costs and environmental impact.

[0018] Further, the aluminum alloy core box includes an upper core box mold 105, a first core box half mold 106, a second core box half mold 107, a third core box half mold 108, a fourth core box half mold 109, and a core box bottom mold 110. The first core box half mold 106, the second core box half mold 107, the third core box half mold 108, and the fourth core box half mold 109 are respectively disposed at the upper end of the upper core box mold 105, and the core box bottom mold 110 is disposed at the upper end of the first core box half mold 106, the second core box half mold 107, the third core box half mold 108, and the fourth core box half mold 109. The core box cavity is formed by the upper core box mold 105, the first core box half mold 106, the second core box half mold 107, the third core box half mold 108, the fourth core box half mold 109, and the core box bottom mold 110.

[0019] In this embodiment, the aluminum alloy core box is designed with multiple parts, which can effectively improve the dimensional accuracy and surface quality of the sand core 104. It can reduce the decrease in accuracy caused by mold deformation or wear, thereby ensuring the high quality of the casting 100. The multi-part structural design makes the assembly and disassembly of the core box more flexible, simplifies the core making process, and is especially suitable for the production of sand cores 104 with complex shapes. It can significantly improve production efficiency. At the same time, aluminum alloy material has good recyclability, reducing resource waste in the production process. The high precision and low deformation rate of the aluminum alloy core box reduce waste caused by mold replacement.
