[0022] 1. Handle; 2. Flexible metal wire; 3. Rubber sleeve; 4. Rough sleeve. DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example:

[0025] See also Figure 1-Figure 2 The utility model provides a coated sand mold burr grinding tool, including a handle 1, a flexible metal wire 2 is fixedly installed on one end of the handle 1, a rubber sleeve 3 is glued and covered on the flexible metal wire 2, and a rough sleeve 4 is glued and covered on the rubber sleeve 3.

[0026] Specifically, Figure 1 and Figure 2 As shown, the rubber sleeve 3 includes an arc surface and a plane, and the end of the rubber sleeve 3 is an arc end. The rough sleeve 4 includes an arc surface and a plane, and the end of the rough sleeve 4 is an arc end. When the arc surface and the arc end are deburred, it is not easy to damage the mold body and produce scratches, and the plane can remove burrs quickly and efficiently.

[0027] Specifically, the rough cover 4 is a cotton yarn cover, which has low cost and is made of the same material as the gloves.

[0028] Working principle:

[0029] When in use, hold the handle 1, make the rough sleeve 4 contact with the burrs of the coated sand mold, and use the rough sleeve 4 to remove them. The flexible metal wire 2 has the function of bending and shaping, and can bend the rough sleeve 4 into a required shape for use. There are various removal methods for the burrs, such as arc sweeping, flat sweeping, vertical cutting, straight pounding, and hooking back.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
