Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments to assist understanding of the invention. The terms used in the utility model are conventional terms in the industry if no special provisions are made.

Referring to fig. 1-5, the utility model provides a sand mould 3DP print head cleaning device, it is equipped with mounting plate 1, is equipped with clearance mechanism on mounting plate 1, and clearance mechanism is equipped with collecting region 2, clearance district 3 and erases district 4, and clearance district 3 sets up collecting region 2 and erases between district 4. The collecting area 2 is provided with a resin pressing groove 21 for collecting resin, the cleaning area 3 is provided with a cleaning liquid groove 31 and a scraping plate 32, the cleaning liquid groove 31 is used for storing cleaning liquid, and the erasing area 4 is provided with an erasing mechanism. The resin pressing tank 21 is fixedly arranged at the upper end of the mounting bottom plate 1 through a first support plate 51, the lower end of the erasing mechanism is fixedly arranged at the upper end of the mounting bottom plate 1 through a second support plate 52, and the cleaning liquid tank 31 is fixedly arranged above the mounting bottom plate 1 through a third support plate 53.
