In the description of the present invention, unless there is an explicit limitation, the words such as setting, installation, connection, etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above words in combination with the specific contents of the technical solution.

Referring to fig. 1, a doctor blade mold for a printer includes a lower mold 10, an upper mold 20, and an injection guide mechanism 30. The lower die 10 can house the blade holder 1 and the blade 2. The upper mold 20 may be press-fitted with the lower mold 10. The injection guide mechanism 30 is disposed at one end of both the lower mold 10 and the upper mold 20 for conveying the glue solution.

Referring to fig. 3 to 6, the lower mold 10 includes a lower substrate 11, a tool rest groove 12, and a lower cavity 13. The tool holder pocket 12 has an outer corner 121. The outer corner 121 may be used for the inner corner of the holder 1 to abut. The lower cavity 13 is arranged on the lower base plate 11 and positioned at one side of the tool rest groove 12 and used for molding the scraper 2.

Referring to fig. 7 to 10, the upper mold 20 includes an upper substrate 21 and an upper cavity 22. The upper substrate 21 may be pressed with the lower substrate 11. The upper cavity 22 is provided on the upper substrate 21. When the upper substrate 21 and the lower substrate 11 are pressed, the upper cavity 22 and the lower cavity 13 are combined to form a cavity 40.

Further, referring to fig. 3 to 6, the lower mold 10 includes a plurality of tool holder slots 12. A plurality of tool rest grooves 12 are uniformly arranged on the lower base plate 11. The number of the lower cavities 13 is several. The lower cavity 13 is disposed intermediate adjacent tool holder pockets 12. The upper cavity 22 is provided with a plurality of cavities. The plurality of upper cavities 22 correspond to the plurality of lower cavities 13 one to one. The plurality of cavities 40 can be used for carrying out injection molding work on a plurality of scrapers synchronously, and the injection molding efficiency is greatly improved.

Further, the lower mold 10 further includes a plurality of tool post positioning posts 14. A plurality of tool post location posts 14 are disposed on one side of the tool post channel 12. A plurality of tool post positioning posts 14 are evenly arranged along the length direction of the tool post groove 12. The tool rest positioning column 14 can enable a worker to quickly install the tool rest 14, and efficiency of the worker is greatly improved.

Of course, it should be noted that, in some embodiments of the present invention, two lower molds 10 may be fixed on both sides of a supporting plate. The two upper dies 20 can press the two lower dies 10 from the upper side and the lower side of the support plate respectively, and at this time, the lower dies 10 are made of magnetic materials and can adsorb the knife rest 1, so that the knife rest 1 on the lower dies 10 positioned below the support plate is prevented from falling off.

Further, the inner surface of the cavity 40 is polished to have a surface roughness Ra of less than or equal to 3.2.

Of course, it should be noted that the inner surface of the cavity 40 is polished to reduce the viscosity of the blade 2 and the cavity 40, so that the mold can be more easily removed. Meanwhile, the smooth inner surface of the cavity 40 enables the surface of the scraper 2 to be flat, and the whole scraper is transparent and more attractive.

Referring to fig. 1, 2 and 5 to 10, the injection guide mechanism 30 includes a lower pressure plate 31, an upper pressure plate 32, an injection hole 33, and a guide groove 34. The lower pressure plate 31 is provided at one end of the lower substrate 11. The upper platen 32 is disposed at one end of the upper substrate 21 and opposite to the lower platen 31. The injection holes 33 include a lower half hole 331 and an upper half hole 332. The lower half hole 331 is provided on the lower pressure plate 31. The upper half-hole 332 is provided on the upper platen 32. Channels 34 include lower channels 341 and upper channels 342. The lower guiding groove 341 is opened on the lower pressing plate 31. The upper diversion trench 342 is formed on the upper press plate 32. The diversion groove 34 is used for communicating the injection hole 33 with the cavity 40. The guide groove 34 is not communicated with the tool holder groove 12.

Of course, it can be understood that the injection guide mechanism 30 is different from the conventional sealing plate manner, and the guide groove 34 can effectively guide the glue to flow to the cavity 40, so that too much glue is not wasted.

The utility model discloses a when printer scraper mould used, at first spouted the one deck release agent on bed die 10, settled knife rest 1 on bed die 10 afterwards. And then the upper mold 20 is pressed with the lower mold 10. The upper pressing plate 32 and the lower pressing plate 31 are synchronously pressed, and thus, a complete injection molding hole 33 and a diversion trench 34 are formed. Glue solution is injected from the injection molding hole 33 and enters each cavity 40 through the diversion trench 34. And after the glue solution is preliminarily shaped, separating the upper die 20 from the lower die 10, and taking out the scraper.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
