Document Type and Number:
WIPO Patent Application WO/2023/284587
Kind Code:
A1
Abstract:
A low-pressure aluminum casting mold and a low-pressure aluminum casting process for a motor rotor. The low-pressure aluminum casting mold comprises an upper blade profile assembly, a lower blade profile assembly, a rotor iron core (1), a dummy shaft (2) and a flow divider (7). The upper blade profile assembly comprises an upper backing plate (3) and an upper mold (4), and the lower blade profile assembly comprises a lower backing plate (5) and a lower mold (6). The low-pressure aluminum casting mold further comprises a first pressing device (8) and four sets of second pressing devices (9). The low-pressure aluminum casting process comprises cold lamination, heating of the rotor iron core, mold preparation, hot lamination and low-pressure casting.
