Abstract
This utility model relates to the field of automotive wheel hub manufacturing technology and discloses a rapid exhaust and cooling device for automotive wheel hub molds, including an exhaust pin cover plate, an exhaust pipe, and an intelligent digital exhaust fan. The exhaust pin cover plate is locked onto the upper mold by a series of screws arranged in a ring at equal intervals to achieve a sealed fixation. The exhaust pipe includes four exhaust branch pipes and one exhaust main pipe. One end of each of the four exhaust branch pipes is connected to the exhaust pin cover plate, and the other end is connected to the exhaust main pipe. The exhaust main pipe is connected to the intelligent digital exhaust fan. The intelligent digital exhaust fan adjusts the exhaust interval and exhaust time according to the casting mold conditions, enabling rapid exhaust and cooling, improving production efficiency and wheel hub qualification rate, and also recovering high-temperature gas to heat bath water to save resources. It solves the problems of slow cooling and shrinkage cavities through efficient exhaust and utilizes exhaust waste heat for resource recovery, combining the advantages of production optimization and energy saving.
