[0030] As Figures 1 to 7 shown, a width adjustment assembly 10 of a preferred embodiment of an embodiment of the present utility model includes a fixed clamp 11, a slurry isolation block 16, and a slurry isolation plate 19. The slurry isolation block 16 is used to fill and seal part of the storage cavity 31 and the discharge chute 34. The slurry isolation block 16 is connected to the slurry isolation plate 19. The slurry isolation plate 19 is used to be installed on one side of the cartridge body 30 and the cartridge cover 40 that forms the discharge chute 34. One end of the fixed clamp 11 is connected to the slurry isolation plate 19, and the other end of the fixed clamp 11 is used to be connected to the cartridge cover 40.

[0031] A casting machine cartridge, as Figures 1 to 7As shown in the figure, it includes a cartridge body 30, a cartridge cover 40, and a width adjustment assembly 10. The cartridge body 30 is provided with a material storage cavity 31, a cartridge opening 32, and a feed inlet 33. The cartridge opening 32 is communicated with the material storage cavity 31. The cartridge cover 40 is connected to the cartridge opening 32. An outlet chute 34 is formed on one side after the cartridge body 30 and the cartridge cover 40 are closed. A slurry isolation block 16 is located in the material storage cavity 31, and the outer peripheral surface of the slurry isolation block 16 is in contact with the inner wall of the material storage cavity 31. The slurry isolation block 16 isolates the material storage cavity 31 to form a material storage cavity section 35. The material storage cavity section 35 is respectively communicated with the feed inlet 33 and the outlet chute 34. A slurry isolation plate 19 is located outside the cartridge body 30, and one side of the slurry isolation plate 19 facing the outlet chute 34 is in contact with the outer side surface of the cartridge body 30 and the outer side surface of the cartridge cover 40 respectively.

[0032] For the width adjustment assembly 10 and the casting machine cartridge of the present utility model, the material storage cavity 31 and the outlet chute 34 are arranged corresponding to each other in the width direction and communicated. The slurry isolation block 16 is placed in the material storage cavity 31, and the outer peripheral surface of the slurry isolation block 16 is in contact with the inner wall of the material storage cavity 31 and the groove wall of the outlet chute 34 respectively. The slurry isolation plate 19 is located on one side of the cartridge body 30, and one side of the slurry isolation plate 19 facing the outlet chute 34 is in contact with the outer side surfaces of the cartridge body 30 and the cartridge cover 40 respectively. The slurry isolation block 16 further isolates the material storage cavity 31 and the outlet chute 34 in the width direction to form a material storage cavity section 35. The material storage cavity section 35 is communicated with the feed inlet 33. The slurry isolation block 16 is connected to the slurry isolation plate 19. By moving the slurry isolation block 16, the width of the material storage cavity section 35 can be adjusted, thereby controlling the flow width of the slurry in the material storage cavity 31. One side of the slurry isolation plate 19 facing the outlet chute 34 is in contact with the outer side surfaces of the cartridge body 30 and the cartridge cover 40, so that the outflow of the slurry is controlled within the adjusted width, thereby realizing obtaining a green body with the desired width according to the demand, and also being able to adjust the size of the cartridge feeding area according to the amount of the remaining slurry, thus avoiding waste of the green body and the slurry and reducing the production cost. One end of the fixed clamp 11 is connected to the cartridge cover 40, and the other end is connected to the slurry isolation plate 19, realizing the limitation of the slurry isolation plate 19 and the slurry isolation block 16, and avoiding the movement of the slurry isolation plate 19 and the slurry isolation block 16 during use.

[0033] Further, as Figures 2 to 3As shown, the fixing clip 11 and the slurry isolation block 16 are located on the same side of the slurry isolation plate 19. One end of the fixing clip 11 is connected to the upper end of the slurry isolation plate 19. The other end of the fixing clip 11 is provided with a limiting groove 15 and a limiting fixing member. The cartridge cover 40 is provided with a cover connection hole 41. The limiting fixing member is connected to the cover connection hole 41 through the limiting groove 15. One end of the fixing clip 11 is connected to the upper end of the slurry isolation plate 19, so as not to affect the fitting degree of the slurry with the cartridge body 30 and the cartridge cover 40 respectively, and ensure that the slurry flows out of the discharge slot 34 corresponding to the material storage cavity section 35. The end of the fixing clip 11 far from the slurry isolation plate 19 is connected to the cartridge cover 40 through the limiting fixing member, which improves the position stability of the slurry isolation plate 19 and prevents the slurry isolation plate 19 from moving during use.

[0034] As one embodiment, the limiting fixing member is a bolt. The limiting fixing member is threadedly connected to the cover connection hole 41. When the limiting fixing member is threadedly connected to the cover connection hole, the fixing clip 11 is clamped between the limiting fixing member and the cartridge cover 40.

[0035] Further, as Figures 1 to 4 shown, one end of the fixing clip 11 is provided with a first connection hole 14 and a clip part fixing member. The upper end of the slurry isolation plate 19 is provided with a plate connection hole 20. The first connection hole 14 and the plate connection hole 20 are connected through the clip part fixing member to realize the connection between the fixing clip 11 and the slurry isolation plate 19.

[0036] As one embodiment, the first connection hole 14 is an M6 through hole.

[0037] Further, as Figure 6 shown, the width of the material storage cavity 31 extends along the first direction X, and the slurry isolation plate 19 extends along the second direction Y. Among them, the first direction X is perpendicular to the second direction Y. A plurality of first connection holes 14 are provided, and adjacent first connection holes 14 are spaced along the second direction Y. The position and number of the plate connection holes 20 are correspondingly set with those of the first connection holes 14. The connection range between the fixing clip 11 and the slurry isolation plate 19 is extended, and the connection reliability between the fixing clip 11 and the slurry isolation plate 19 is improved.

[0038] Further, as Figure 1 and Figure 4 shown, the extending direction of the limiting groove 15 is perpendicular to the extending direction of the slurry isolation plate 19. Cover connection holes 41 are respectively provided corresponding to the lower parts at both ends of the limiting groove 15. The limiting fixing members are respectively connected to the cover connection holes 41 through the ends of the limiting groove 15. Both ends of the limiting groove 15 are respectively connected to the cover connection holes 41 through the limiting fixing members, which improves the connection reliability between the fixing clip 11 and the cartridge cover 40.

[0039] As one embodiment, as Figure 1 and Figure 4As shown, two lid connection holes 41 and plate connection holes 20 are respectively arranged below the corresponding positions at both ends of the limit groove 15 in a triangular layout, improving the connection stability between the lifting fixture 11 and the material box lid 40 and the slurry isolation plate 19.

[0040] Furthermore, as Figure 2 shown, the fixing clip 11 includes a first fixing rod 12 and a second fixing rod 13. One end of the second fixing rod 13 is connected to the first fixing rod 12. The first fixing rod 12 and the second fixing rod 13 are arranged in a T shape. The limit groove 15 is provided on the first fixing rod 12, and the first connection hole 14 is provided at the end of the second fixing rod 13 away from the first fixing rod 12. The T-shaped structure makes the fixing clip 11 have stronger stability. When the T-shaped fixing clip 11 is used to fix or connect an object, the T-shaped structure can effectively resist lateral force and torsional force, maintaining the firmness of the connection.

[0041] Furthermore, as Figure 2 and Figure 3 shown, the slurry isolation block 16 includes a cavity filling block 17 whose shape corresponds to the shape of the material storage cavity 31 and a discharge filling block 18 whose shape corresponds to the shape of the discharge slot 34. One end of the discharge filling block 18 is connected to the upper end of the cavity filling block 17, and the other end of the discharge filling block 18 is connected to the slurry isolation plate 19. The shapes of the cavity filling block 17 and the discharge filling block 18 respectively correspond to the shapes of the material storage cavity 31 and the discharge slot 34, ensuring that the slurry will not leak or overflow from an unexpected path in the material storage cavity 31. It improves the accuracy of the slurry flowing from the material storage cavity 31 to the discharge slot 34. By connecting the cavity filling block 17 and the slurry isolation plate 19 through the discharge filling block 18, a stable support structure is formed, enhancing the structural stability of the width adjustment assembly 10.

[0042] Furthermore, as Figure 3 and Figure 4As shown in the figure, a sealing protrusion 42 protrudes from one side of the cartridge cover 40 facing the cartridge body 30. The sealing protrusion 42 extends into the material storage cavity 31. The sealing protrusion 42 is provided with a first side surface 44 and a second side surface 45 arranged oppositely. The first side surface 44 faces the discharge chute 34, and the second side surface 45 is away from the discharge chute 34 and is in contact with the inner wall of the material storage cavity 31. A discharge channel 43 is formed between the first side surface 44 and the discharge chute 34, and the discharge channel 43 communicates with the discharge chute 34. The sealing protrusion 42 extends into the material storage cavity 31 and is in close contact with the inner wall of the material storage cavity 31, enhancing the sealing performance between the cartridge cover 40 and the cartridge body 30. The second side surface 45 in contact with the inner wall of the material storage cavity 31 ensures the integrity and continuity of the sealing surface, further improving the sealing effect. The first side surface 44 of the sealing protrusion 42 faces the discharge chute 34, and a discharge channel 43 is formed between the first side surface 44 and the discharge chute 34, enabling the slurry to smoothly flow through the discharge channel 43 into the discharge chute 34 when discharging. The connectivity between the discharge channel 43 and the discharge chute 34 ensures the continuous supply of the slurry.

[0043] Further, as Figure 1 and Figure 6 shown in the figure, at least two width adjustment components 10 are provided, and a material storage cavity section 35 is formed between adjacent width adjustment components 10. By moving the two width adjustment components 10 to adjust the width of the material storage cavity section 35, when the position of the feed port 33 is in the middle of the cartridge body 30, the position of the material storage cavity section 35 is limited to the position corresponding to the feed port 33 through the two width adjustment components 10, making the width adjustment of the material storage cavity section 35 more flexible.

[0044] In summary, the embodiment of the present utility model provides a width adjustment assembly 10 and a casting machine material box. The storage cavity 31 and the discharge chute 34 are arranged corresponding to each other in the width direction and communicated. The slurry isolation block 16 is placed in the storage cavity 31. The outer peripheral surface of the slurry isolation block 16 is respectively attached to the inner wall of the storage cavity 31 and the wall of the discharge chute 34. The slurry isolation plate 19 is located on one side of the material box body 30, and the side of the slurry isolation plate 19 facing the discharge chute 34 is respectively attached to the outer side surfaces of the material box body 30 and the material box cover 40. The slurry isolation block 16 further isolates the storage cavity 31 and the discharge chute 34 in the width direction into a storage cavity section 35. The storage cavity section 35 is communicated with the feed inlet 33. The slurry isolation block 16 is connected to the slurry isolation plate 19. By moving the slurry isolation block 16, the width of the storage cavity section 35 is adjusted, thereby controlling the flow width of the slurry in the storage cavity 31. The side of the slurry isolation plate 19 facing the discharge chute 34 is attached to the outer side surfaces of the material box body 30 and the material box cover 40, so that the outflow of the slurry is controlled within the adjusted width, thereby obtaining a green body with the desired width according to requirements. The size of the feeding area of the material box can also be adjusted according to the amount of the remaining slurry, so as to avoid waste of the green body and the slurry and reduce the production cost. One end of the fixed clamp 11 is connected to the material box cover 40, and the other end is connected to the slurry isolation plate 19, realizing the limitation of the slurry isolation plate 19 and the slurry isolation block 16, and avoiding the movement of the slurry isolation plate 19 and the slurry isolation block 16 during use.

[0045] The above is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present utility model, several improvements and substitutions can still be made, and these improvements and substitutions should also be regarded as the protection scope of the present utility model.
