[0039] The following is for reference. Figures 1 to 8 This invention describes a dispensing device for multiple pouring nozzles according to an embodiment of the present invention.

[0040] like Figures 1 to 4As shown, the dispensing device for multiple pouring nozzles according to an embodiment of the present invention includes a sealing assembly 100, a pouring head assembly 200, a sliding guide assembly 300, a pouring nozzle assembly 400, a sliding drive mechanism 600, and a lifting mechanism. The sealing assembly 100 is disposed in the first mounting hole 901 of the pouring tank 900; the pouring head assembly 200 is disposed in the sealing assembly 100; the sliding guide assembly 300 is disposed in the sealing assembly 100 and located inside the pouring tank 900; the pouring nozzle assembly 400 includes a slide 41. The 900 includes a pouring tank 900 and a plurality of pouring nozzles 420 disposed on a slide table 410. The slide table 410 and the sliding guide assembly 300 are slidably engaged. The plurality of pouring nozzles 420 are spaced apart along the sliding direction of the slide table 410. A sliding drive mechanism 600 is disposed on the pouring tank 900 and can drive the slide table 410 to slide relative to the sliding guide assembly 300. A lifting mechanism is disposed on the sealing assembly 100 and can drive the pouring head assembly 200 and the pouring nozzle assembly 400 to move relative to each other so that the pouring head assembly 200 and the pouring nozzle 420 are connected.

[0041] By driving the slide table 410 to move via the sliding drive mechanism 600, different pouring nozzles 420 can be aligned with the pouring head assembly 200. Then, by driving the pouring head assembly 200 and the pouring nozzle assembly 400 to move relative to each other via the lifting mechanism, the pouring head assembly 200 and the pouring nozzle 420 can be connected, thereby realizing the delivery of the pouring material. The requirements of multiple pouring nozzle applications can be met by moving the slide table 410, and there is no need to open holes according to the number of pouring nozzles, reducing the number of openings on the pouring tank, making the vacuum pouring equipment more stable and reliable.

[0042] Specifically, by using the aforementioned mechanism, the number of openings on the casting tank is reduced, thereby reducing the configuration of sealing structures such as sealing rings and gaskets, thus reducing the occurrence of sealing leaks and improving the reliability and stability of the vacuum casting equipment.

[0043] like Figure 7 As shown, in some embodiments of this utility model, the slide 410 has an elongated structure, and multiple pouring nozzles 420 are distributed at intervals along the length of the slide 410. The number of pouring nozzles 420 can be configured according to specific needs. By centrally setting the pouring nozzles 420, not only can the requirements of multiple pouring nozzle applications be met, but also, during cleaning, the slide 410 and pouring nozzles 420 can be directly cleaned, making cleaning and maintenance convenient and reducing maintenance costs.

[0044] like Figure 6 , Figure 7 As shown, in some embodiments of this utility model, the lifting mechanism is located on the sealing assembly 100 and connected to the sliding guide assembly 300. The lifting mechanism drives the pouring nozzle assembly 400 to move relative to the pouring head assembly 200 through the sliding guide assembly 300, thereby realizing the docking of the pouring nozzle 420 and the pouring head assembly 200.

[0045] Specifically, the pouring head assembly 200 is fixed to the sealing assembly 100 and includes a feed pipe that can dock with the pouring nozzle 420. The pouring nozzle assembly 400 is located inside the pouring tank 900. The docking of the pouring nozzle 420 and the pouring head assembly 200 can be achieved by moving the pouring nozzle assembly 400. Since the pouring head assembly 200 is fixed to the sealing assembly 100, it will not move, which can ensure a good sealing effect between it and the sealing assembly 100 and reduce the risk of leakage.

[0046] It is understood that in some embodiments of this utility model, the pouring head assembly 200 can also be configured to be movable, and the pouring head assembly 200 can be moved to dock with the pouring nozzle 420 by a lifting mechanism, which can also meet the connection and conduction requirements.

[0047] like Figure 1 , Figure 3 , Figure 4 As shown, in some embodiments of this utility model, the sealing assembly 100 includes a sealing flange 110 installed to the first mounting hole 901, and the pouring head assembly 200 is disposed on the sealing flange 110, thereby realizing the installation of the pouring head assembly 200.

[0048] Specifically, the sealing flange 110 is installed to the first mounting hole 901 by bolts, screws, etc., and a sealing element such as a sealing ring or sealing gasket is provided between the flange and the first mounting hole 901 to achieve a better sealing effect.

[0049] It is understood that in some embodiments of this utility model, the sealing assembly 100 may also adopt a flip-top mechanism. The rotatable cover, in conjunction with the locking mechanism, can also meet the installation requirements of the sealing and pouring head assembly 200, the lifting mechanism, etc.

[0050] like Figure 6 , Figure 7 As shown, in some embodiments of this utility model, the lifting mechanism is a cylinder 510 disposed on the sealing flange 110, and the piston rod 520 of the cylinder 510 is connected to the sliding guide assembly 300, thereby realizing the driving of the sliding guide assembly 300.

[0051] It is conceivable that, in some embodiments of this utility model, the lifting mechanism may also be a lead screw mechanism, an electric cylinder mechanism, a rack and pinion mechanism, etc., which can also meet the driving requirements of the sliding guide assembly 300.

[0052] like Figure 6 , Figure 7 , Figure 8As shown, in some embodiments of this utility model, the sliding guide assembly 300 includes a connecting frame 310 and a guide member 320 disposed on the connecting frame 310. The slide table 410 is an elongated structural member. The guide member 320 is used to support the slide table 410 and is provided with a sliding groove 321 corresponding to the slide table 410 to meet the requirement that the slide table 410 can be slidably disposed.

[0053] In some embodiments of this utility model, the connecting bracket 310 is used to connect with the piston rod 520 of the cylinder 510, thereby meeting the lifting and lowering drive requirements of the sliding guide assembly 300.

[0054] In some embodiments of this utility model, the sliding guide assembly 300 further includes an upper limiting assembly that can restrict the upward movement of the slide table 410. Together with the slide groove 321, it forms a sliding channel corresponding to the cross-sectional profile of the slide table 410, thereby improving the positional accuracy of the slide table 410 and thus improving the matching accuracy between the pouring head assembly 200 and the pouring nozzle 420.

[0055] like Figure 6 , Figure 7 As shown, in some embodiments of this utility model, the upper limiting component includes limiting members 331 disposed at one or both ends of the guide member 320. The limiting members 331 are located above the slide groove 321, and a limiting opening is formed between the limiting members 331 and the slide groove 321, which allows the slide table 410 to move only along its length direction, thereby satisfying the sliding requirements of the slide table 410 and ensuring its positional accuracy.

[0056] In some embodiments of this utility model, the limiting member 331 is configured as two sets and is respectively provided at both ends of the guide member 320, forming a limiting opening at both ends of the guide member 320, so as to improve the positional accuracy of the slide table 410 when it moves in and out.

[0057] like Figure 4 , Figure 6 , Figure 7 , Figure 8 As shown, in some embodiments of this utility model, the upper limiting component includes a rolling element 332 rotatably disposed on the connecting frame 310 and located above the slide groove 321. The rolling element 332 can press against the slide table 410 located above the slide groove 321 to limit the slide table 410 from moving upward and improve the positional accuracy of the slide table 410.

[0058] In some embodiments of this utility model, the rolling element 332 is a roller, a wheel, etc., and is closely attached to the slide table 410 to ensure its positional accuracy. The rolling performance of the rolling element 332 is utilized to enable the slide table 410 to maintain good sliding performance.

[0059] like Figure 4As shown, in some embodiments of this utility model, at least two rolling elements 332 are configured, with at least one rolling element 332 located on one side of the pouring head assembly 200 and at least one rolling element 332 located on the other side of the pouring head assembly 200, thereby enabling the slide table 410 to maintain good positional accuracy at the position corresponding to the pouring head assembly 200.

[0060] like Figure 4 As shown, in some embodiments of this utility model, two rolling elements 332 are configured, located on the front and rear sides of the pouring head assembly 200 along the sliding direction of the slide table 410, respectively, to accurately position the part of the slide table 410 located at the pouring head assembly 200, thereby improving the fitting accuracy between the pouring head assembly 200 and the pouring nozzle 420.

[0061] It is conceivable that in some embodiments of this utility model, the rolling element 332 may be configured as three or more as needed, which will not be described in detail here.

[0062] In some embodiments of this utility model, the sliding drive mechanism 600 is connected to the slide table 410 via a push-pull rod 610. The push-pull rod 610 is movably connected to the slide table 410 so that the slide table 410 can move up and down normally with the sliding guide assembly 300 and can slide normally.

[0063] like Figure 4 , Figure 5 As shown, in some embodiments of this utility model, the slide table 410 is provided with a connecting part 411, the connecting part 411 is provided with an elongated hole 412 extending in the vertical direction, and the end of the push-pull rod 610 is provided with a connecting shaft 611 that can pass through the elongated hole 412 and slide within the elongated hole 412. When the slide table 410 moves up and down, the connecting shaft 611 can slide up and down within the elongated hole 412, thereby avoiding interference with the normal lifting and lowering movement of the slide table 410.

[0064] It is understood that in some embodiments of this utility model, an elongated hole may be provided at the end of the push-pull rod 610 and a connecting shaft may be provided at the connecting part 411, thereby enabling the push-pull rod 610 and the slide table 410 to be movably connected.

[0065] It is conceivable that in some embodiments of this utility model, the push-pull rod 610 and the slide table 410 can also be movably connected by a linkage mechanism, a slider mechanism, etc., so that the slide table 410 can move up and down relative to the push-pull rod 610.

[0066] like Figures 2 to 5As shown, in some embodiments of this utility model, the sliding drive mechanism 600 includes a drive motor assembly 620 and a lead screw transmission mechanism 630. The drive motor assembly 620 is connected to the push-pull rod 610 through the lead screw transmission mechanism 630 to drive the push-pull rod 610 to move along the sliding direction of the slide table 410.

[0067] In some embodiments of this utility model, the lead screw transmission mechanism 630 includes a lead screw and a nut. One of the lead screw and the nut is connected to the output shaft of the drive motor assembly 620, and the other is connected to the push-pull rod 610, thereby realizing the linear movement drive of the push-pull rod 610 (moving along the sliding direction of the slide table 410).

[0068] like Figure 3 As shown, in some embodiments of this utility model, the drive motor assembly 620 is installed to the second mounting hole 902 of the casting tank 900 through the motor mounting flange 640, so that the drive motor assembly 620 is externally mounted to maintain the normal performance of the drive motor assembly 620.

[0069] Specifically, the push-pull rod 610 and the lead screw drive mechanism 630 are both located inside the casting tank 900, and the output shaft of the drive motor assembly 620 is connected to the lead screw drive mechanism 630 through a coupling.

[0070] It is understood that, in some embodiments of this utility model, the sliding drive mechanism 600 may also be a motor-driven rack and pinion mechanism, an electric cylinder mechanism, etc.

[0071] Of course, this invention is not limited to the above-described embodiments.
