The invention provides a novel injection mold quick cleaning device. The novel injection mold quick cleaning device comprises a base, a drain pipe, a cleaning tank and a control panel. The cleaning tank is embedded and connected to the interior of the right side of the base. The drain pipe penetrates through and is connected to the right side of the bottom surface of the interior of the cleaning tank. The control panel is fixedly connected to the front surface of the base. A mounting seat is fixed to the left side of the upper surface of the base. A lifting cylinder is fixed to the upper surface of the mounting seat. The upper portion of the lifting cylinder is connected with a telescopic column. The top end of the telescopic column is fixedly connected with a top surface plate. In the cleaning process, an ultrasonic generator is turned on through the control panel to enable an ultrasonic probe to conduct crushing on stubborn residues in an injection mold to avoid the influence of uncleaned stubborn residues on the next-time injection molding quality; moreover, a protective cover can achieve the good protection effect on the ultrasonic probe to prevent the injection mold from touching the ultrasonic probe by mistake and damaging the ultrasonic probe. The novel injection mold quick cleaning device is suitable for production and application and has good development prospects.
