Description

Technical Field

[0001] The utility model belongs to the field of molten aluminum casting, and in particular relates to a molten aluminum casting water blocking device. Background Art

[0002] Aluminum bars are the basic material for various aluminum products. During the production process, aluminum blocks need to be melted in a casting furnace to form molten aluminum. The molten aluminum is then discharged through a discharge port and introduced into the mold cavity through a guide chute for casting. Preventing the molten aluminum from leaking out is crucial. In order to prevent the aluminum from leaking out and causing waste, it is usually necessary to seal the discharge port after the aluminum is discharged.

[0003] However, although the molten aluminum no longer flows through the guide trough after being blocked, some of the previous molten aluminum will inevitably adhere to the guide trough. If it is not cleaned in time, it will be difficult to clean after the molten aluminum is completely solidified, and long-term accumulation will affect the patency of the guide trough. For this reason, a molten aluminum blocking device is proposed. Utility Model Content

[0027] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] like Figure 1 As shown, a molten aluminum blocking device comprises a base 1, a furnace 2 is fixed on the upper end of the base 1, and an aluminum ingot is placed in the furnace for heating and melting to form aluminum liquid; Figure 2 As shown, a discharge port 21 is provided on one side of the lower end of the melting furnace 2, through which molten aluminum can be discharged; a mounting groove 22 is provided on the upper end of the discharge port 21, and a blocking component 3 is provided at the mounting groove 22 to control the blocking or opening of the discharge port 21;

[0029] like Figure 3 As shown, the blocking assembly 3 includes a lifting connecting plate 33, a blocking plate 34 that cooperates with the mounting groove 22 is fixed to the lower end of the connecting plate 33, and the blocking plate 34 can be lowered to block the discharge port 21;

[0030] In this embodiment, the sealing assembly 3 also includes a mounting plate 31 fixed to the outside of the furnace 2, and a first cylinder 32 is fixed on the mounting plate 31. The driving shaft of the first cylinder 32 is fixed to the connecting plate 33 and can drive the connecting plate 33 to rise and fall; in other embodiments, the first cylinder 32 can be replaced and the connecting plate 33 can be driven to rise and fall by arranging linear driving components such as hydraulic cylinders and telescopic rods on the mounting plate 31.

[0031] In addition, when the blocking plate 34 blocks the discharge outlet 21 , the connecting plate 31 contacts the upper end surface of the discharge outlet 21 and can block and conceal the installation groove 22 , thereby preventing material leakage at the installation groove 22 .

[0032] A material guide assembly 4 is provided on the base 1. Figure 4 As shown, the material guide assembly 4 includes a slidable material guide trough 41. The material guide trough 41 can slide to the discharge port 21 and guide the discharged molten aluminum into the mold to be cast into aluminum bars. When it is necessary to clean the molten aluminum remaining in the material guide trough 41, the material guide trough 41 can be slid away from the mold to clean out the molten aluminum in the material guide trough 41, thereby preventing the molten aluminum from falling into the mold during cleaning and affecting the use of the mold.

[0033] In this embodiment, if Figure 4 As shown, a support rod 411 is fixed to the lower end of the guide trough 41, and the support rod 411 is slidably connected to the base 1. Two first fixed plates 42 are fixed to the upper end of the base 1, and a first screw rod 43 is rotatably connected between the two first fixed plates 42. The first screw rod 43 passes through the support rod 411 and is threadedly connected thereto. By arranging a motor on one of the first fixed plates 42 to drive the first screw rod 43 to rotate, the sliding position of the guide trough 41 can be adjusted; and the first screw rod 43 has self-locking properties, that is, the thread lead angle of the first screw rod 43 is less than the equivalent friction angle, so as to ensure that the sliding position of the guide trough 41 remains stable after adjustment.

[0034] In other embodiments, the guide trough 41 may be directly driven to slide and adjust by providing a hydraulic cylinder, a telescopic rod or other linear driving components on the base 1 .

[0035] The guide trough 41 is provided with a scraper assembly 5, which can promptly scrape off the residual aluminum liquid in the guide trough 41 to avoid it being difficult to clean after solidification; Figure 5 As shown, the scraper assembly 5 includes a mounting frame 51 that can slide along the length of the guide trough 41. A second cylinder 52 is provided on the mounting frame 51. A scraper 53 is fixed to the drive shaft of the second cylinder 52. Under the drive of the second cylinder 52, the pressure plate 53 can enter the guide trough 41 and cooperate with its inner cavity. As the mounting frame 51 slides, it can scrape off the molten aluminum adhering to the guide trough 41.

[0036] In this embodiment, the mounting bracket 51 is slidably connected to the guide trough 41 in the length direction of the guide trough 41. Two second fixed plates 54 are provided on one side of the guide trough 41. A second screw rod 55 is rotatably connected between the two second fixed plates 54. The second screw rod 55 passes through the mounting bracket 51 and is threadedly connected thereto. By providing a motor on one of the second fixed plates 54 to drive the second screw rod 55 to rotate, the mounting bracket 51 can be driven to slide. In addition, in order to ensure that the position of the mounting bracket 51 remains stable after adjustment, the second screw rod 55 also has self-locking properties, that is, the thread lead angle of the second screw rod 55 is smaller than the equivalent friction angle.

[0037] In other embodiments, the mounting frame 51 may be directly driven to slide by providing a linear driving component such as a hydraulic cylinder or a telescopic rod on the material guide trough 41 .

[0038] A locking assembly 6 is provided on one side of the connecting plate 33 to lock the guide trough 41 at the discharge outlet 21 when discharging molten aluminum, thereby preventing the guide trough 41 from leaving the discharge outlet 21 due to misoperation, resulting in leakage and waste of molten aluminum. In addition, when the discharge outlet 21 is blocked, the position lock of the guide trough 41 can be unlocked to facilitate control of the guide trough 41 away from the mold and to clean the guide trough 41.

[0039] like Figure 6 As shown, the engaging assembly 6 includes a fixing frame 61 fixed on the connecting plate 33, a fixing rod 62 is fixed to the lower end of the fixing frame 61, a positioning rod 63 is slidably connected to the fixing rod 62, and the positioning rod 63 and the fixing rod 62 are elastically connected by a spring 64 (i.e., the two ends of the spring 64 are respectively fixedly connected to the lower end of the positioning rod 63 and the fixing rod 62), and a positioning hole 412 is opened on the guide trough 41, and the positioning rod 63 can be inserted into the positioning hole 412 and cooperate with the positioning hole 412;

[0040] Moreover, when the blocking plate 34 does not completely block the discharge outlet 21, the positioning rod 63 can be inserted into the positioning hole 412 and cooperate with the positioning hole 412 to lock the material guide trough 41 at the discharge outlet 21 for material guiding; when the blocking plate 34 completely blocks the discharge outlet 21, the positioning rod 63 just leaves the positioning hole 412, and the locking of the material guide trough 41 is canceled at this time, and it can slide in the direction away from the mold, thereby facilitating the cleaning of the inside of the material guide trough 41.

[0041] In this embodiment, a limiting groove 621 is opened on the fixing rod 62, and the positioning rod 63 fixes the limiting block 631. The limiting block 631 is located in the limiting groove 621, and under the elastic force of the spring 64, the limiting block 631 is tightly attached to the top of the limiting groove 621 and can prevent the positioning rod 63 from detaching from the fixing rod 62.

[0042] Working principle:

[0043] By providing a blocking assembly 3 at the discharge port 21, the discharge port 21 can be controlled to be blocked and opened. By providing a slidable and adjustable material guide trough 41 on the base 1, the material guide trough 41 can slide to the discharge port 21 to guide the molten aluminum into the mold to complete the casting of the aluminum bar. Moreover, when the material guide trough 41 needs to be cleaned, the material guide trough 41 is controlled to be away from the mold, which can prevent the molten aluminum from falling onto the mold during cleaning and affecting the use of the mold. By providing a scraper assembly 5 on the material guide trough 41, the molten aluminum adhering to the inside of the material guide trough 41 can be cleaned and scraped away in time, preventing the molten aluminum from being difficult to remove after solidification. By providing a locking assembly 6 on one side of the connecting plate 33, the position of the material guide trough 41 is locked at the discharge outlet 21 when discharging molten aluminum, thereby avoiding misoperation that causes the material guide trough 41 to leave the discharge outlet 21 when discharging molten aluminum, resulting in leakage and waste of molten aluminum; in addition, when the discharge outlet 21 is blocked, the position locking of the material guide trough 41 can be canceled to facilitate the control of the material guide trough 41 away from the mold and to clean the material guide trough 41.
