This spraying method improves labor efficiency and reduces labor intensity. However, this spraying method uses a large number of nozzles, which increases the likelihood of nozzle clogging, making maintenance difficult. In addition, it cannot guarantee the uniformity of the liquid volume sprayed by each nozzle. Furthermore, the nozzle position cannot be adjusted, and when the mold changes, the mold surface cannot be fully covered during spraying, often requiring manual re-spraying. SUMMARY
