[0009] In one possible implementation: the displacement range of each adjustment region along the second direction is 0.1mm-0.5mm.
[0010] In one possible implementation: the mold component further includes a filler disposed along a second direction on the side of the runner adjustment component opposite to the first plane. The filler covers the protrusion.
[0011] In one possible implementation: the filler has a protrusion on the side facing the adjustment member, the flow channel adjustment member has a mating groove on the side facing the filler, and the mating groove is located between adjacent protrusions, with the protrusion and the mating groove corresponding to each other.

[0049] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.
[0051] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.
[0052] Some embodiments of this application are described in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0053] See Figures 1 to 6 This embodiment provides a mold accessory 100, including a runner adjusting component 10 and an adjusting rod 20. The runner adjusting component 10 extends along a first direction A. Along a second direction B, a first plane 11 is provided on one side of the runner adjusting component 10, and a plurality of protrusions 12 are provided on the other side. The plurality of protrusions 12 are spaced apart along the first direction A. The first direction A intersects the second direction B. The first plane 11 includes a plurality of adjusting areas 111, which are arranged side by side along the first direction A. The plurality of protrusions 12 are correspondingly arranged with the plurality of adjusting areas 111. The adjusting rod 20 is arranged along the second direction B and connected to the protrusions 12.
[0054] The mold accessory 100 of this application is used in a coating mold 200. The flow channel adjustment component 10 can be assembled in the inner cavity of the coating mold 200, so that the first plane 11 is located on one side of the inner cavity of the coating mold 200. It is used to squeeze the slurry in the mold cavity, so that the slurry is evenly distributed at the slurry outlet of the mold, thereby achieving the coating effect. The adjustment rod 20 can be used to push the protrusion 12 on the flow channel adjustment component 10 to adjust the position of the corresponding adjustment area 111 on the first plane 11 in the second direction B, thereby changing the size of the flow channel in the cavity of the coating mold 200, affecting the local pressure of the cavity, and thus adjusting the coating accuracy. Furthermore, due to the integrity of the first plane 11, adjacent adjustment areas 111 are smoothly connected. When different adjustment areas 111 are adjusted, no obvious step surface is generated between adjacent adjustment areas 111, effectively reducing quality problems such as bulging or dark marks on the coating surface and improving the coating quality.
[0055] In addition, the flow channel adjustment component 10 in this application has a long strip structure. The integrated flow channel adjustment component 10 not only makes the first plane 11 have integrity and continuity, eliminating the step surface and gap between adjacent adjustment areas 111, but also avoids cleaning dead corners and dry material accumulation between adjacent adjustment areas 111, ensuring the smooth progress of the coating process, and making overall disassembly and cleaning more convenient.
[0056] It should be noted that, Figure 2 The dashed lines between adjacent adjustment regions 111 are only used for differentiation. In actual applications, the first plane 11 is a whole structure, and the dashed lines may not exist.
[0057] Please see Figures 1 to 3 In some embodiments, there are multiple adjusting rods 20, each corresponding to a protrusion 12. Each protrusion 12 has a recess 121 on its side facing away from the first plane 11, and a portion of the adjusting rod 20 is located within the recess 121. Along the second direction B, the depth of the recess 121 is less than the thickness of the protrusion 12. Thus, each adjusting region 111 can be independently adjusted by the interaction between the protrusion 12 and the adjusting rod 20, allowing for adjustment of the local pressure in the slurry flow channel cavity according to actual needs, thereby adjusting the local coating density, further improving coating accuracy and quality. Limiting the depth of the recess 121 to less than the thickness of the protrusion 12 avoids the recess 121 from damaging the integrity of the first plane 11, which helps ensure coating quality.
[0058] In some embodiments, the outer surface of one end of the adjusting rod 20 inserted into the recess 121 is threadedly engaged with the inner surface of the recess 121 to fix the relative position of the adjusting rod 20 and the protrusion 12. When the adjusting rod 20 moves along the second direction B, it can simultaneously drive the protrusion 12 and the corresponding adjusting area 111 to produce displacement in the second direction B. In other embodiments, the adjusting rod 20 can also be connected to the protrusion 12 by snap-fit connection, external clamp fixation, welding, adhesive bonding, or other detachable or fixed connection methods, as long as the installation design requirements are met, and this application is not limited to this.
[0059] In some embodiments, along the first direction A, a groove 13 is formed between adjacent protrusions 12. Along the second direction B, the distance between the bottom surface of the groove 13 and the first plane 11 is H, and the distance between the side of the protrusion 12 away from the first plane 11 and the bottom surface of the groove is D, where H < D. Thus, the flow channel adjusting member 10 forms an alternating thickness structure in the first direction A, with a thinner thickness at the connection point of adjacent adjusting regions 111, providing a certain degree of elasticity and facilitating independent adjustment of the position of the adjusting region 111 in the second direction B by the adjusting rod 20 via the protrusions 12.
[0060] Please see Figure 3 In one embodiment, the protrusion 12 has a curved or inclined surface structure on its side 122 along the first direction A, meaning that the thickness of the protrusion 12 gradually decreases from the top side of the protrusion 12 towards the centerline of the adjacent groove 13. This is to ensure that each protrusion 12 can cover as much of the corresponding adjustment area 111 as possible, improving adjustment accuracy, while also reducing the influence of the thickness of the protrusion 12 on the displacement of the adjustment area 111.
[0061] Please see Figure 4 In another embodiment, the protrusion 12 can also be approximately rectangular, with its side surface 122 approximately perpendicular to the bottom surface of the groove 13. A perpendicularity error within 5°, or an angle between the side surface 122 of the protrusion 12 and the bottom surface of the groove 13 between 85° and 90°, can be considered perpendicular. This allows for a thinner thickness at the connection between adjacent adjustment areas 111, and each adjustment area 111 can be adjusted more flexibly, which is beneficial for further improving coating accuracy and quality.
[0062] In some embodiments, the displacement range of each adjustment region 111 along the second direction B is 0.1mm-0.5mm. That is, the adjustment rod 20 pushes the protrusion 12 to move in the second direction B, thereby causing the corresponding adjustment region 111 to be displaced within the range of 0.1mm-0.5mm, so as to fully meet the adjustment requirements of the flow channel cavity in the coating process. In some embodiments, the displacement of each adjustment region 111 along the second direction B can be 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, or any value within a range, as long as the design requirements are met, and this application is not limited to this.
[0063] Please see Figure 5 In some embodiments, the mold component 100 further includes a filler 30 disposed along the second direction B on the side of the flow channel adjuster 10 opposite to the first plane 11. The filler 30 covers the protrusion 12.
[0064] Thus, when the flow channel adjuster 10 is installed into the coating mold 200, the filler 30 can fill the gap between the flow channel adjuster 10 and the mounting groove 41, preventing excessive slurry from entering the mounting groove 41 and affecting the coating quality. The filler 30 is a flexible material and can integrally cover the side of the flow channel adjuster 10 facing away from the first plane 11. Alternatively, the filler 30 can be configured as a multi-segment structure, arranged sequentially to cover multiple protrusions 12 and the grooves 13 between the protrusions 12.
[0065] In some embodiments, the adjusting rod 20 may also pass through the filler 30 to position the filler 30.
[0066] In some embodiments, the filler 30 has a protrusion 31 on the side facing the adjusting member, and the flow channel adjusting member 10 has a mating groove 14 on the side facing the filler 30, with the mating groove 14 located between adjacent protrusions 12, and the protrusion 31 corresponding to the mating groove 14. In this way, the filler 30 can be positioned with the flow channel adjusting member 10 through a convex-concave mating structure, preventing the filler 30 from falling off and reducing the gap between the filler 30 and the flow channel adjusting member 10.
[0067] Please see Figure 6 and Figure 7 This application also provides a coating mold 200, including the mold accessory 100, upper mold 40, and lower mold 50 described in the above embodiments. The upper mold 40 has a mounting groove 41 on one side along the second direction B, and the mounting groove 41 extends along the first direction A. A flow channel adjusting member 10 of the mold accessory 100 is disposed in the mounting groove 41, and the first plane 11 of the flow channel adjusting member 10 faces the opening of the mounting groove 41. The lower mold 50 is disposed opposite to the upper mold 40 along the second direction B, and the flow channel adjusting member 10 is disposed between the upper mold 40 and the lower mold 50.
[0068] Specifically, the slurry cavity is formed between the lower mold 50 and the upper mold 40. The opening of the mounting groove 41 faces the slurry cavity. When the flow channel adjusting member 10 is installed in the mounting groove 41, the first plane 11 is located on one side of the slurry cavity along the second direction B. The adjusting rod 20 is connected to the protrusion 12 on the flow channel adjusting member 10, and the end of the adjusting rod 20 away from the flow channel adjusting member 10 extends out of the upper mold 40, so as to adjust the position of multiple adjusting areas 111 on the first plane 11 from the outside, thereby realizing local or overall adjustment of the coating density and improving the coating quality.
[0069] In some embodiments, the mounting groove 41 is provided with a through hole 42, which corresponds to the protrusion 12 of the flow channel adjusting component 10, and the adjusting rod 20 of the mold accessory 100 passes through the through hole 42. Specifically, the through hole 42 can be provided one-to-one with the adjusting rod 20. On the one hand, it can position the adjusting rod 20, and on the other hand, it can simplify the sealing structure between the adjusting rod 20 and the through hole 42, avoiding the situation where a through hole 42 needs to be matched with multiple adjusting rods 20, which would require custom-made irregular seals, and reducing the problem of slurry leakage.
[0070] In some embodiments, the coating mold 200 further includes an adjusting ruler 60, which is disposed along the second direction B on the side of the upper mold 40 away from the first plane 11. The adjusting ruler 60 is connected to the adjusting rod 20. The adjusting ruler 60 includes, but is not limited to, a micrometer or similar device. Thus, the movement distance of the adjusting rod 20 along the second direction B can be precisely controlled by the adjusting ruler 60.
[0071] In some embodiments, a bracket 70 is also provided on the outer side of the upper mold 40, and an adjusting scale 60 is mounted on the bracket 70 and connected to the adjusting rod 20 along the second direction B. When the adjusting scale 60 is a micrometer, the adjusting rod 20 can be moved back and forth along the second direction B by rotating the knob on the micrometer. The adjusting scale 60 can also be set one-to-one with the adjusting rod 20 to realize independent adjustment of each adjusting rod 20.
[0072] Please refer to it again. Figure 7 The embodiments of this application also provide a coating apparatus 300, including the coating mold 200 and coating roller 80 described in the above embodiments, wherein the coating roller 80 is rotatably disposed on one side of the coating mold 200.
[0073] Specifically, the slurry outlet of the coating mold 200 is positioned facing the coating roller shaft 80. The substrate 301 to be coated passes through the coating mold 200 and the coating roller shaft 80 and is wound around the coating roller shaft 80. When the coating roller shaft 80 rotates, it can drive the substrate 301 to move relative to the slurry outlet. The slurry extruded from the outlet adheres to the substrate 301 and moves with the substrate 301, forming a coating 302 on the surface of the substrate 301. The mold accessory 100 of this application is installed in the coating mold 200. The adjustment rod 20 can push the protrusion 12 on the flow channel adjustment component 10 to adjust the position of the corresponding adjustment area 111 on the first plane 11 in the second direction B, thereby changing the size of the cavity flow channel in the coating mold 200, affecting the local pressure of the cavity, and thus adjusting the coating accuracy. The adjacent adjustment areas 111 are smoothly connected, and when different adjustment areas 111 are adjusted, there will be no obvious step surface between them, thereby effectively reducing quality problems such as bulging or dark marks on the coating surface and improving the coating quality.
[0074] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of this application should not depart from the spirit and scope of the technical solutions of this application.
