Description

Technical Field

[0001] This utility model belongs to the field of metal casting technology, and specifically relates to a quantitative addition device for casting auxiliary materials. Background Technology

[0002] In the metal casting process, auxiliary materials such as borax are added to effectively reduce internal impurities in the metal and improve the strength of the cast metal.

[0003] Currently, Chinese utility model patent CN214768794U discloses an auxiliary material adding device for centrifugal casting of rolls. While existing auxiliary material adding devices can add auxiliary materials during the metal casting process, the required amount of auxiliary material varies depending on the type and quantity of materials used in metal casting. Furthermore, existing devices cannot adjust the amount of auxiliary material discharged from the discharge port according to casting needs, making it difficult to accurately control the amount added and failing to meet practical requirements. Additionally, because existing devices can only add auxiliary materials through the discharge port, they tend to concentrate the material in localized areas, preventing even distribution of the auxiliary material within the metal casting mold and thus reducing the efficiency of the metal casting process. Utility Model Content

[0004] The purpose of this invention is to provide a quantitative addition device for casting auxiliary materials, which has the advantages of being able to adjust the quantitative addition of auxiliary materials according to casting needs and improving the uniformity of the added auxiliary materials.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a quantitative addition device for casting auxiliary materials, including an auxiliary material tank, a quantitative cylinder bolted to the bottom of the auxiliary material tank, a through hole communicating with the inside of the quantitative cylinder at the bottom of the inner cavity of the auxiliary material tank, a sliding disc slidably connected to the inside of the quantitative cylinder, a discharge screw tube threaded through the quantitative cylinder and fixedly connected to the bottom of the sliding disc, an insertion rod slidably inserted into the discharge screw tube at the bottom of the inner cavity of the quantitative cylinder, and a baffle plate that cooperates with the through hole is slidably inserted between the auxiliary material tank and the quantitative cylinder.

[0006] By employing the above technical solution, the auxiliary material inside the auxiliary material tank can be quantitatively discharged into the metering cylinder as needed through the sliding adjustment of the storage space at the top of the sliding disc. After the through-hole is sealed, the auxiliary material inside the metering cylinder is then discharged. This allows for adjustment of the auxiliary material discharge rate according to casting requirements, facilitating quantitative addition. The material discharged from the discharge screw is dispersed through the first and second distribution holes on both sides of the conical seat, while the conical seat rotates at the bottom of the connecting sleeve. This allows the auxiliary material to rotate and be discharged downwards from inside the first and second distribution holes, improving the uniformity of the added auxiliary material.

[0007] The present invention is further configured such that: a connecting sleeve is fixedly sleeved at the bottom of the discharge screw tube, a conical seat is provided at the bottom of the connecting sleeve, a T-shaped rotating cylinder is welded to the top of the conical seat and is rotatably connected to the connecting sleeve, a central hole and a first distributing hole communicating with the inside of the discharge screw tube are respectively opened at the center and on both sides of the conical seat, and a second distributing hole communicating with the inside of the central hole is opened on both sides of the bottom of the conical seat.

[0008] By adopting the above technical solution, the excipients can be rotated and discharged downwards from the inside of the first and second dispensing holes, thereby improving the uniformity of the excipients after addition.

[0009] The present invention is further configured such that a sealing cover plate is hinged to the top of the auxiliary material tank.

[0010] By adopting the above technical solution, the top of the auxiliary material tank can be covered, thereby preventing dust from falling into the interior when not in use.

[0011] The present invention is further configured such that a sealing ring is fixedly sleeved on the surface of the sliding disk and slidably connected to the inner wall of the metering cylinder.

[0012] By adopting the above technical solution, the sealing between the sliding disc surface and the metering cylinder is improved, preventing the auxiliary material from leaking downwards.

[0013] The present invention is further configured such that: the end of the baffle plate near the through hole and the inside of the through hole are both bolted with magnet blocks that are attracted to each other by magnetic force.

[0014] The above technical solution facilitates fixing the baffle plate inside the through hole by the magnetic attraction of the magnet block.

[0015] The present invention is further configured such that a scale is marked on one side of the surface of the metering cylinder.

[0016] The above technical solution facilitates precise adjustment of the height of the sliding plate through the through-scale, thereby controlling the amount of auxiliary materials used.

[0017] The present invention is further configured such that: both sides inside the connecting sleeve are rotatably connected to ball bearings that are slidably connected to the T-shaped rotating cylinder.

[0018] By adopting the above technical solution, the frictional force of the T-shaped rotating drum rotating inside the connecting sleeve is reduced, and the rotational stability is improved.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. By adjusting the storage space at the top of the sliding disc, the auxiliary material inside the auxiliary material tank can be quantitatively discharged into the metering cylinder as needed. After the through hole is sealed, the auxiliary material inside the metering cylinder is then discharged. This allows for adjustment of the auxiliary material discharge rate according to casting requirements, facilitating quantitative addition.

[0021] 2. The material discharged from the discharge screw is dispersed through the first and second distribution holes on both sides inside the conical seat, while the conical seat is rotated at the bottom of the connecting sleeve. This allows the auxiliary material to rotate and be discharged downwards from inside the first and second distribution holes, improving the uniformity of the added auxiliary material.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Example 1:

[0028] refer to Figure 1 , Figure 2 A quantitative addition device for casting auxiliary materials includes an auxiliary material tank 1, a metering cylinder 2 bolted to the bottom of the auxiliary material tank 1, a through hole 3 communicating with the inside of the metering cylinder 2 at the bottom of the inner cavity of the auxiliary material tank 1, a sliding disc 4 slidably connected inside the metering cylinder 2, a discharge screw 7 threadedly connected to the bottom of the sliding disc 4 and passing through the metering cylinder 2, and an insertion rod 5 welded to the bottom of the inner cavity of the metering cylinder 2, slidably inserted into the discharge screw 7. A baffle plate 6, which works in conjunction with the through hole 3, is slidably inserted between the auxiliary material tank 1 and the metering cylinder 2. By adjusting the storage space at the top of the sliding disc 4, the auxiliary material inside the auxiliary material tank 1 can be quantitatively discharged into the metering cylinder 2 as needed, and after the through hole 3 is sealed, the auxiliary material inside the metering cylinder 2 is discharged. This allows for adjustment of the auxiliary material discharge rate according to casting needs, facilitating quantitative addition.

[0029] refer to Figure 2 A sealing ring 15 is fixedly fitted onto the surface of the sliding disc 4 and slidably connected to the inner wall of the metering cylinder 2. This improves the sealing between the surface of the sliding disc 4 and the metering cylinder 2, preventing the auxiliary material from leaking downwards.

[0030] refer to Figure 2 Magnet blocks 16, which are attracted to each other by magnetic force, are bolted to one end of the baffle plate 6 near the through hole 3 and inside the through hole 3. This allows the baffle plate 6 to be fixed inside the through hole 3 by the magnetic attraction of the magnet blocks 16.

[0031] refer to Figure 1 The measuring cylinder 2 has a scale 17 marked on one side. This allows for precise adjustment of the height of the sliding disc 4 through the scale 17, thereby controlling the amount of auxiliary materials used.

[0032] Brief description of the usage process: When adding a specific amount of auxiliary material, pour the auxiliary material into the auxiliary material tank 1. Rotate the discharge screw tube 7 to engage with the threaded feed cylinder 2, causing the sliding disc 4 to slide up and down inside the feed cylinder 2, adjusting the storage space at the top of the sliding disc 4. Then, pull the baffle plate 6 out from the through hole 3, allowing the auxiliary material in the auxiliary material tank 1 to slide down through the through hole 3. Because the auxiliary material is blocked by the sliding disc 4, it stops falling after filling the top space of the sliding disc 4. The amount of auxiliary material added can be controlled by adjusting the storage space at the top of the sliding disc 4. Furthermore, the auxiliary material cannot be discharged through the discharge screw tube 7 because the insert rod 5 is inserted and sealed inside. Finally, the through hole 3 is resealed by sliding the baffle plate 6, causing the sliding disc 4 to slide down inside the feed cylinder 2. After the insert rod 5 slides out of the discharge screw tube 7, the measured amount of auxiliary material in the feed cylinder 2 can be discharged through the discharge screw tube 7 for addition.

[0033] Example 2:

[0034] refer to Figure 1 , Figure 2 , Figure 3 A quantitative additive device for casting auxiliary materials includes a connecting sleeve 8 fixedly sleeved to the bottom of a discharge screw tube 7. A conical seat 9 is located at the bottom of the connecting sleeve 8, and a T-shaped rotating cylinder 10, rotatably connected to the connecting sleeve 8, is welded to the top of the conical seat 9. The conical seat 9 has a central hole 12 and a first distribution hole 11 communicating with the interior of the discharge screw tube 7 on its center and two sides, respectively. A second distribution hole 13 communicating with the interior of the central hole 12 is located on both sides of the bottom of the conical seat 9 on both sides of the central hole 12. The material discharged from the discharge screw tube 7 is dispersed through the first and second distribution holes 11 and 13 on both sides of the conical seat 9. Simultaneously, the conical seat 9 rotates at the bottom of the connecting sleeve 8, allowing the auxiliary material to rotate and be discharged downwards from the interior of the first and second distribution holes 11 and 13, improving the uniformity of the added auxiliary material.

[0035] refer to Figure 1 , Figure 2 The top of the auxiliary material container 1 is hinged with a sealing cover 14. This covers the top of the auxiliary material container 1, thus preventing dust from falling into the interior when it is not in use.

[0036] refer to Figure 3 Both sides inside the connecting sleeve 8 are rotatably connected to ball bearings 18 that are slidably connected to the T-shaped rotating drum 10. This reduces the friction of the T-shaped rotating drum 10 rotating inside the connecting sleeve 8 and improves rotational stability.

[0037] Brief description of the usage process: The auxiliary material is discharged downwards into the conical seat 9 through the discharge screw tube 7. A portion of the auxiliary material can slide to both sides through the first distribution hole 11 and be discharged from the bottom edge of the conical seat 9. At the same time, another portion of the auxiliary material slides down through the central hole 12 and is then discharged downwards through the second distribution holes 13 on both sides. Finally, by moving the conical seat 9, the T-shaped rotating drum 10 is rotated inside the connecting sleeve 8, so that the first distribution hole 11 and the second distribution hole 13 can rotate to different positions at the bottom of the conical seat 9, thereby allowing the auxiliary material to be added by rotating downwards from different positions at the bottom of the conical seat 9.
