Existing core shooters often suffer from insufficient sand shooting pressure during core making, leading to the scrapping of batches of sand cores, increasing production costs and reducing efficiency. This is especially true for hot cores of complex castings, where insufficient sand shooting pressure from existing core shooters results in incomplete sand injection, making operation time-consuming and labor-intensive for workers.

[0003] Therefore, it is essential to provide an auxiliary device to increase the sand-shooting pressure of the core shooter in order to address the shortcomings of the existing technology. Utility Model Content

[0042] The present invention will be further described in conjunction with the following embodiments.

[0043] Example 1.

[0044] like Figure 1-5 As shown, an auxiliary device for increasing the sand-shooting pressure of a core shooter includes a vertical core shooter body 1, which has a vertical parting structure. The vertical core shooter body includes a sand box 2 and a vertical core shooter frame 3, and a sand-shooting mechanism 4 is installed on the top of the vertical core shooter frame 3.

[0045] like Figure 1-5 As shown, the sand-shooting mechanism 4 includes a sand-shooter body 5. An auxiliary sand-shooting component 6 is installed at the sand-shooting port of the sand-shooter body 5. The sand outlet of the auxiliary sand-shooting component 6 abuts against the sand inlet of the sand box 2. The auxiliary sand-shooting component 6 includes a pressure-boosting box 7. The pressure-boosting box 7 has a primary pressure-boosting chamber 8 and a secondary pressure-boosting chamber 9 arranged from top to bottom inside. The primary pressure-boosting chamber 8 and the secondary pressure-boosting chamber 9 are provided with an inner cavity shell 10 outside. The inner cavity shell 10 is integrally formed with the pressure-boosting box 7. The primary pressure-boosting chamber 8 and the secondary pressure-boosting chamber 9 are connected through each other.

[0046] like Figure 1-5 As shown, the primary pressurizing chamber 8 is connected to the sand injection port of the sand ejector body 5, and the secondary pressurizing chamber 9 is connected to the sand inlet of the sand box 2. A pressure regulating component 11 is installed at the bottom of the secondary pressurizing chamber 9. The inner cavity shell 10 is connected to the sand inlet of the sand box 2 through the pressure regulating component 11. A drive gear 12 is movably installed on the outside of the pressure regulating component 11. A motor 13 is axially installed at one end of the drive gear 12. The motor 13 is installed on the inner wall of the pressurizing chamber 7. A positioning rod 14 is axially installed between the other end of the drive gear 12 and the inner cavity shell 10.

[0047] like Figure 1-5 As shown, the pressure regulating component 11 includes a hollow disc 15, which is horizontally installed on the inner wall of the inner cavity shell 10 of the secondary booster chamber 9. The hollow structure on the hollow disc 15 is semi-circular. A cylinder 16 is installed below the hollow disc 15. A hollow plate 17 is integrally formed at one end of the cylinder 16 near the hollow disc 15. Two circular through holes 18 of different diameters are opened on the hollow plate 17. A sealed bearing A19 is installed on the outer side of the cylinder 16.

[0048] like Figure 1-5 As shown, the outer ring of the sealed bearing A19 is fixedly installed on the bottom inner wall of the inner cavity housing 10. An external gear ring 20 is installed on the outer side of the cylinder 16. The external gear ring 20 is driven by the drive gear 12. A sealed bearing B21 is installed on the bottom outer side of the cylinder 16. The outer ring of the sealed bearing B21 is installed on the bottom of the sand box 2. The bottom of the cylinder 16 is connected to the sand inlet of the sand box 2.

[0049] like Figure 1-5 As shown, the volume of the first-stage booster chamber 8 is larger than that of the second-stage booster chamber 9. The first-stage booster chamber 8 has a cubic structure, while the second-stage booster chamber 9 has a cylindrical structure.

[0050] The sand ejector body 5 sends the sand into the primary pressurization chamber 8. Since the primary pressurization chamber 8 has a large volume, it can temporarily store a certain amount of sand. Then the sand enters the secondary pressurization chamber 9, which has a relatively small volume. According to the principles of fluid mechanics, the sand flows faster in this chamber, and the pressure is initially increased. At the same time, the motor 13 starts, driving the drive gear 12 to rotate. The drive gear 12 meshes with the external gear ring 20, causing the cylinder 16 to rotate. The perforated plate 17 on the cylinder 16 rotates accordingly. When the circular through holes 18 of different diameters on the perforated plate 17 are aligned with the semi-circular perforated structure of the perforated disc 15, the flow area of ​​the sand can be adjusted, further controlling the sand flow rate and pressure, achieving precise adjustment of the sand ejection pressure, so that the sand enters the sand box 2 with sufficient pressure, ensuring the compactness of the sand ejection. The sealing bearings A and B ensure the sealing of the cylinder 16 during rotation, preventing sand leakage, and making the rotation of the cylinder 16 smoother.

[0051] This invention uses a primary pressurizing chamber 8 and a secondary pressurizing chamber 9 to initially pressurize the sand material by changing its volume. Then, through the pressure regulating component 11, the sand material flow area can be precisely adjusted to further control the sand shooting pressure. This effectively solves the problem of insufficient sand shooting pressure in existing core shooting machines, which leads to incomplete sand shooting. It improves the quality of sand core production, reduces production costs, and increases production efficiency.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
