摘要： The invention relates to the field of aluminum wheel casting molds, and more particularly relates to a closed-loop control method and system for a mold temperature in a wheel casting process. The control method includes: step 1, acquiring data, that is, acquiring a plurality of mold position temperatures, and cooling pipeline opening and closing signals in a target wheel casting process according to a fixed frequency; step 2, storing, based on acquired mold opening and closing signals of casting equipment, the acquired data in a database in the form of a unique ID according to a single wheel casting process; step 3, calculating new process parameters based on the acquired plurality of position temperatures and time; and step 4, integrating the calculated process parameters, and issuing the process parameters to a PLC of a casting equipment to perform new casting. According to the invention, the temperature control parameters are calculated based on the acquired temperature data and time process to form the temperature control process of the casting process, which solves the technical problem of significant fluctuations in the quality of the low-pressure casting process of aluminum wheels and improves casting stability and yield.

摘要： The present invention discloses a low-pressure aluminium casting mold and a low-pressure aluminium casting process for motor rotor. The low-pressure aluminium casting mold includes an upper blade profile assembly, a lower blade profile assembly, a rotor core (1), a dummy shaft (2) and a diverter (7), the upper blade profile assembly includes an upper backing plate (3) and an upper mold (4), the lower blade profile assembly includes a lower backing plate (5) and a lower mold (6). The low-pressure aluminium casting mold further includes a first pressing device (8) and four sets of second pressing devices (9). The low-pressure aluminium casting process includes the steps of cold lamination, heating of the rotor core, mold preparation, hot lamination and low-pressure casting.
