[0031] Figures 1 to 5 An embodiment of the ink spill prevention printing fixture of this application is illustrated schematically.

[0032] like Figures 1 to 5 As shown, this application discloses an anti-ink overflow printing fixture, which includes: a contour mold 10, which is a ring structure with a contour through hole 11 in the center for the product to be printed 30, and the contour through hole 11 is surrounded by a planar structure of equal height; a fastening base 20, on which a strip positioning frame 21 is provided, the contour mold 10 can be inserted into the strip positioning frame 21 and is flush with the surface of the fastening base 20, the strip positioning frame 21 and the contour mold 10 are interference fit, and one end of the strip positioning frame 21 is provided with a retaining edge 22 for positioning the contour mold 10.

[0033] Through the above structural design, this application can use the contour mold 10 to wrap and cover the sides of the product 30 to be printed, and form a printing support plane with its plane flush with the fastening base 20. This reduces the chance of the curved edge of the top surface of the product 30 being contacted by the screen printing mesh, thereby avoiding the formation of ink overflow areas and reducing the intensity of manual repair. At the same time, the fastening base 20 also serves to position the contour mold 10 and clamp it to make it fit more closely with the product 30 to be printed, further improving the printing quality. In addition, the anti-ink overflow printing fixture structure of this embodiment is relatively simple, has low processing difficulty, and can be reused. It only needs to be checked periodically for cracks or wear problems of the contour mold 10, resulting in low production costs and suitability for industrial promotion.

[0034] In some embodiments of this application, multiple copying molds 10 are provided, and the copying through holes 11 of each copying mold 10 are customized according to the corresponding product 30 to be printed. The outer edge shape of multiple copying molds 10 is set to a uniform square, so that the same set of fastening bases 20 can be used for printing, thereby reducing the adaptability of printing fixtures and the overall cost. Among them, such as Figures 1 to 3 As shown, the four corners of the square outer edge of each contour mold 10 are rounded to facilitate assembly and easy insertion into the strip positioning frame 21 of the fastening base 20. This application embodiment only shows a schematic diagram of a contour mold 10 for a circular product. It is understood that the product 30 to be printed is not limited to this shape. Square, triangular or other irregular shapes can also be printed using the printing fixture of this application.

[0035] In some embodiments of this application, multiple strip positioning frames 21 may be provided on the fastening base 20 to simultaneously match multiple copying molds 10 for printing operations, thereby improving production efficiency.

[0036] In some embodiments of this application, such as Figures 1 to 5 As shown, the strip positioning frame 21 extends from the retaining edge 22 to one side of the fastening base 20, forming an open entrance 25 to facilitate the insertion and removal of the pre- and post-printing molding die 10. Wherein, as Figures 1 to 5 As shown, the bottom edge of the strip positioning frame 21 is provided with a piece-removing groove 23. The piece-removing groove 23 is a recessed groove structure, which is used to suspend the edge of the contour mold 10 to allow gas to flow, thereby avoiding the gas pressure adsorption effect, and at the same time providing gap space to facilitate the removal of the contour mold 10 by hand or fork and other tools.

[0037] In some embodiments of this application, such as Figures 1 to 5 As shown, a pick-and-place notch 24 is provided at the edge 22 of the strip positioning frame 21. The pick-and-place notch 24 is connected to the strip positioning frame 21. Meanwhile, as... Figure 4 As shown, the take-up slot 23 extends from the inside of the strip positioning frame 21 to the take-up and put-out notch 24 to provide a gap for easy removal of the mold 10.

[0038] In some embodiments of this application, reference is made to Figure 2 As shown, the inner wall of the through hole 11 of the contouring mold 10 is divided into upper and lower sections. The upper section is vertically arranged, thus forming... Figure 2 The vertical section 111 in the screen printing process supports the surrounding space of the product 30 to be printed, preventing the screen fabric from contacting the irregular curved area 32 at the top edge of the product during screen printing and avoiding ink overflow. The lower section of the contoured through-hole 11 expands outwards, thus forming... Figure 2The outward expansion section 112 is designed to facilitate the nesting of the product to be printed 30, reducing the difficulty of the nesting operation. Understandably, even though the lower section of the through hole 11 expands outward, it is still in at least partial and relatively close contact with the product to be printed 30 under the clamping action of the strip positioning frame 21 of the fastening base 20, so as to avoid sporadic ink stains seeping into the side of the product and forming an ink overflow area.

[0039] In some embodiments of this application, the outer surface of the contour mold 10 and the inner surface of the strip positioning frame 21 are both polished to make the surfaces in contact with each other smooth, so as to facilitate the sliding movement between the two, so that the contour mold 10 can be moved to the stop edge 22 for positioning, or slid out.

[0040] In some embodiments of this application, the fastening base 20 is a bakelite base, and the contouring mold 10 is a bakelite mold. Both are made of bakelite, which has high mechanical strength, a long service life, and is wear-resistant, heat-resistant, and electrically safe. Alternatively, in some embodiments of this application, the fastening base 20 is a bakelite base, and the contouring mold 10 is a silicone mold, so that the hardness of the mold is slightly lower than that of the fastening base 20, reducing the resistance when it is inserted into the strip positioning frame 21, thus facilitating its use.

[0041] In some embodiments of this application, such as Figures 1 to 5 As shown, all edges of the contour mold 10 and the fastening base 20 are chamfered to eliminate sharp edges, reduce impact damage, and protect the product and operator safety.

[0042] In some embodiments of this application, a fastening mechanism is provided at the bottom of the fastening base 20. The fastening mechanism is used to connect the fastening base 20 to the worktable of the printing equipment to facilitate the installation of the entire printing fixture and to perform reliable printing operations. The fastening mechanism can be a positioning bolt or a positioning suction cup. Alternatively, a simple positioning groove or other structure can be used to fix the fastening base 20, depending on the needs of the printing operation.

[0043] This application also discloses an anti-overflow printing device, which includes an anti-overflow printing fixture as described in the above embodiment. Through the cooperation of the contour mold 10 and the fastening base 20, the edge of the product to be printed 30 can be shielded and the curved or sloping edge of the top surface can be supported, thereby avoiding the occurrence of ink overflow, saving the manual labor for subsequent ink removal, and improving production efficiency.

[0044] Combination Figures 1 to 5 The following diagram illustrates the working principle of this application:

[0045] For the product 30 to be printed as shown in the figure, the flat part of its top surface is the printing area 31, and the curved edges of the sides and top surface are irregular areas 32 where ink overflow needs to be avoided. During printing, the product 30 to be printed is placed in the strip positioning frame 21 of the fastening base 20, and a contour jig is fitted onto the product 30. Then, the nested structure is slid to the left to the stop edge 22 for positioning, and the printing operation can then begin. Since the sides of the product 30 to be printed are wrapped and the top edge is shielded by the plane of the contour mold 10, the screen will not fall into the irregular area 32 of the product during screen printing, thus preventing ink overflow. Therefore, after the printing operation is completed, the contour mold 10 and the product can be removed through the removal notch 24 to proceed to the next process, saving the cost of manually repairing the ink overflow area.

[0046] In summary, the ink-overflow prevention printing fixture of this application includes a contour mold and a fastening base. The contour mold has a ring-shaped structure with a contour through-hole in the center for nesting the product to be printed. The perimeter of the contour through-hole is a planar structure of equal height. A strip-shaped positioning frame is provided on the fastening base. The contour mold can be inserted into the strip-shaped positioning frame, flush with the surface of the fastening base. The strip-shaped positioning frame and the contour mold are interference-fitted, and one end of the strip-shaped positioning frame is provided with a stop edge for positioning the contour mold. This application can use the contour mold to wrap and cover the side of the product to be printed, and use its plane flush with the fastening base to form a printing support plane, reducing the chance of the curved edge of the top surface of the product to be printed coming into contact with the screen printing mesh, avoiding the formation of ink overflow areas and reducing the intensity of manual repair. At the same time, the fastening base also serves to position the contour mold and clamp it to make it fit more tightly with the product to be printed, further improving the printing quality.

[0047] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
