[0029] The outer wall of overglaze head body 5 is provided with a plurality of overglaze grooves 17 at equal intervals, and the overglaze grooves 17 penetrate through both ends of the overglaze head body 5.

[0030] The melt glue screw rod 1 is driven to rotate by the injection molding machine screw, the annular ring 7 is connected with the structure outside the injection molding machine, the melt glue screw rod 1 drives the positioning cylinder 8, the fender pad 9, the positioning sleeve 6, the sleeve ring 16, the overglaze head body 5, and the overglaze groove 17 to rotate, the raw material melted by the injection molding machine enters the surface of the sleeve ring 16 through the gap between the positioning cylinder 8 and the annular ring 7, and is transported to the surface of the overglaze groove 17 by the sleeve ring 16. When the melt glue screw rod 1 rotates at high speed, the sleeve ring 16 rotates synchronously, and the positioning cylinder 8 and the fender pad 9 limit and support it. Since the annular ring 7 is connected with a fixed structure, friction occurs between the sleeve ring 16 and the annular ring 7. The sleeve ring 16 is a consumable part, and in the market, the overglaze head body 5 is usually in direct contact with the annular ring 7. The contact between the overglaze head body 5 and the annular ring 7 increases the wear of the overglaze head body 5, which is made of precious metal material and has a very high replacement cost. When the sleeve ring 16 needs to be replaced after wear, the fender pad 9 is rotated manually with auxiliary tools, the positioning cylinder 8 and the fender pad 9 are separated from the melt glue screw rod 1 by the engagement of the second internal thread 10 and the external thread 2, the annular ring 7 is separated, the overglaze head body 5 is rotated manually with auxiliary tools, the overglaze head body 5 is separated from the melt glue screw rod 1 by the engagement of the first internal thread 4 and the threaded column 3, the positioning sleeve 6 is separated from the melt glue screw rod 1, the positioning sleeve 6 and the sleeve ring 16 are replaced, the overglaze head kit has excellent low-friction performance during use, the wear of the overglaze head is reduced, the consumable part is conveniently replaced, and the cost of later replacement and maintenance of the overglaze head is reduced.
