Patent number: 11491519Abstract: Disclosed is an automatic die cleaning device with reusable cleaning fluid. The automatic die cleaning device includes a robot, a cleaning fluid cyclic-spraying system and a die overturning mechanism. The automatic die cleaning device can spray the cleaning fluid to a die to clean oil stains off the surface of the wheel die, thus realizing the function of automatically cleaning the oil stains off the surface of the die; and the automatic die cleaning device also has the function of reusing the cleaning fluid, thereby saving the cleaning fluid and reducing the influence on the environment. The cleaned die surface is smooth, and the effect is ideal. The automatic die cleaning device reduces the labor intensity, meets the requirement of high-efficiency production, and improves the production efficiency.Type: GrantFiled: October 28, 2019Date of Patent: November 8, 2022Assignee: CITIC Dicastal Co., Ltd.Inventors: Jinling Yang, Xiaoting Zhu, Weizhou Liu, Hongshen Zhang, Yukun Yang, Yingfeng Wang, Zhen Wang, Li Yang
