Description

Technical Field

[0001] The invention relates to the technical field of molten aluminum ladles, in particular to a molten aluminum casting ladle. Background Art

[0002] The ladle is used for casting operations in the foundry. In the production of aluminum alloy castings, the molten aluminum used is mostly transported from the melting furnace to the holding furnace of the casting process using a molten aluminum transfer ladle. The molten aluminum casting ladle is a device used for transferring, storing and pouring molten aluminum. The molten aluminum casting ladles currently used in the market are all simple tank structures that can meet the storage and pouring needs of molten aluminum.

[0003] However, when using traditional aluminum molten ladle, most of them use a driving device to tilt the aluminum molten ladle in the tank and pour the aluminum molten into the casting sand box for casting. When the volume of the aluminum molten ladle is too large, it takes a lot of manpower and material resources to control the pouring of the aluminum molten ladle for casting. Not only is it easy to spill the aluminum molten and cause burns to the workers, but it is also difficult to control the amount of aluminum molten cast.

[0004] In order to reduce the safety hazards when pouring molten aluminum, in the actual production process, molten aluminum is poured through the bottom discharge method. However, during the bottom pouring of molten aluminum, it is also not easy to control the pouring amount of molten aluminum, which increases the difficulty of operation for the staff during the molten aluminum pouring process.

[0037] To make the objectives, technical means, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0038] The embodiment of the present invention solves the technical problems that traditional aluminum casting ladles are difficult to cast aluminum liquid, requiring a large amount of manpower and material resources, by providing an aluminum casting ladle; and the technical problems that traditional aluminum casting ladles are difficult to control the capacity of the cast aluminum liquid, easily casting too much or too little aluminum liquid, which has an adverse effect on the casting work.

[0039] The technical solution in the embodiment of the present invention is to solve the above-mentioned technical problems. The overall idea is as follows: by adding a casting mechanism to the device, the molten aluminum can be poured out without controlling the tilting of a larger ladle, and the casting operation is simpler and more convenient. Compared with the existing molten aluminum casting ladle, a large amount of manpower and material resources are saved, and the work efficiency is high; by adding a series of structural components such as a transmission rod, a slider and an opening and closing mechanism to the device, the capacity of the cast molten aluminum can be automatically controlled, and compared with the existing molten aluminum casting ladle, the waste of molten aluminum is reduced and the casting quality is ensured. It can also automatically realize the casting and closing functions of the molten aluminum without manual control, which greatly improves the practicality of the device.

[0040] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a molten aluminum casting ladle, comprising a ladle body 1, wherein the outer surfaces of the front and rear sides of the ladle body 1 are fixedly connected to the positions near the top thereof, and the upper end surface of the ladle body 1 is hingedly connected to a heat-insulating cover 12;

[0041] The arc-shaped inner wall of the ladle body 1 is embedded with a fixed heating wire, and a through groove 13 is provided on its inner surface near the lower right end, and a filter is fixedly connected to the inner surface of the through groove 13 near the left side, and the right outer surface of the ladle body 1 is fixedly connected to the casting mechanism 2.

[0042] By adopting the above technical solution, when working, the insulation cover 12 is opened, and the molten aluminum is poured into the inside of the ladle body 1, and the insulation cover 12 is closed to reduce the heat loss of the molten aluminum. At the same time, the internal heating wire is controlled to work to keep the molten aluminum inside the ladle body 1 warm. The lifting ear 11 is fixed by the lifting device, and the ladle body 1 is moved as a whole to the mold for casting operation. The casting mechanism 2 is controlled to work, and the molten aluminum inside the ladle body 1 can enter the inside of the casting mechanism 2 through the through groove 13 and be cast into the inside of the casting sand box for casting operation. By fixing the filter screen on the left side of the through groove 13, the solid impurities in the molten aluminum can be effectively prevented from being injected into the inside of the sand box through the casting mechanism 2, thereby ensuring the molding quality of the casting.

[0043] As an embodiment of the present invention, Figures 1 to 4As shown, the casting mechanism 2 includes a measuring cylinder 21, a base 22, a chute 23, a second through groove 24, a driving component 3, and an opening and closing component 5. A measuring cylinder 21 is provided on the right side of the ladle body 1 near the bottom end, and the inner wall of the circumference of the measuring cylinder 21 is embedded and fixedly connected with a heating wire, and its bottom end is fixedly connected with the base 22 by a thread. Slide grooves 23 are provided on the left and right sides of the inner surface of the measuring cylinder 21, and a second through groove 24 is provided through the left and right sides of the inner surface near the bottom end. The height of the second through groove 24 near the left side is higher than the second through groove 24 on the right side. The right outer surface of the ladle body 1 is fixedly connected with the driving component 3 near the top of the measuring cylinder 21, and the outer surfaces of the left and right sides of the measuring cylinder 21 are fixedly connected with the opening and closing component 5 near the bottom. The driving component 3 includes a support plate 31, a hydraulic push rod 32, a transmission plate 33, a fixed cylinder 34, and a transmission rod 35. The right outer surface of the main body 1 is fixedly connected to a support plate 31 near the top, and the bottom end surface of the support plate 31 is symmetrically fixedly connected to a hydraulic push rod 32. The bottom ends of the two groups of hydraulic push rods 32 are fixedly connected to a transmission plate 33. The center position of the upper end surface of the transmission plate 33 is penetrated by an embedded fixed connection with a fixing cylinder 34, and the inner surface of the fixing cylinder 34 is threadedly connected to a transmission rod 35. The bottom end of the transmission rod 35 passes through the measuring cylinder 21, and the two are slidably connected. The bottom end surface of the transmission rod 35 is provided with a limiting groove 4, the inner surface of the limiting groove 4 is slidably connected to the limiting rod 41, and both are T-shaped structural designs that match each other. The bottom end of the limiting rod 41 is fixedly connected to a slider 42, and the slider 42 and the slide groove 23 match each other and are slidably connected. The inside of the limiting groove 4 corresponds to the position between the top of the limiting rod 41 and the top of the inner surface of the limiting groove 4. A spring 43 is provided.

[0044] By adopting the above technical solution, when the ladle body 1 is moved to the specified position, the driving assembly 3 is controlled to work. In the initial state, the slider 42 is located at the bottom end of the measuring cylinder 21, and the hydraulic push rod 32 is controlled to retract, driving the transmission plate 33 to move upward, thereby driving the fixed cylinder 34 to move upward. Since the transmission rod 35 is threadedly connected to the fixed cylinder 34, the transmission rod 35 will be driven to move upward. When the transmission rod 35 moves upward to engage with the limit rod 41, continuing to move upward will drive the limit rod 41 to move upward, thereby driving the slider 42 to move upward along the slide groove 23 In the initial state, the opening and closing assembly 5 near the left side of the measuring cylinder 21 is in the open state, and the opening and closing assembly 5 on the right side is in the closed state. When the slider 42 moves upward inside the measuring cylinder 21, under the action of pressure, the molten aluminum inside the ladle body 1 will enter the measuring cylinder 21 through the through groove 13 and the opening and closing assembly 5 on the left side. Under the action of the heating wire inside the measuring cylinder 21, the molten aluminum can be kept warm to prevent the molten aluminum from solidifying quickly. When the transmission plate 33 moves upward to a certain extent, it can drive the opening and closing assembly 5 on the left side to close, and the injection of molten aluminum into the measuring cylinder 21 is stopped. Inside, an appropriate amount of molten aluminum is stored in the measuring cylinder 21, and at the same time, the right opening and closing component 5 is driven to open, and the molten aluminum in the measuring cylinder 21 will flow out from the right side and be injected into the sand box through the casting nozzle. The user can adjust the distance of the transmission rod 35 extending into the inside of the measuring cylinder 21 by rotating the transmission rod 35 to adjust the position of the limit rod 41 inside the limit groove 4. When the position of the transmission rod 35 is adjusted downward, the top of the limit rod 41 is located near the top of the limit groove 4. When the hydraulic push rod 32 contracts at a uniform speed and drives the transmission rod 35 to move upward, the limit rod 41 is extended. 1 is engaged with the T-shaped limit groove 4, then before the left opening and closing assembly 5 is closed, the transmission rod 35 drives the slider 42 to move upward to a shorter distance, thereby causing less molten aluminum to enter the measuring cylinder 21. Conversely, if the transmission rod 35 is adjusted in the opposite direction to move upward, more molten aluminum will enter the measuring cylinder 21. That is, the user can set the capacity of the casting molten aluminum according to the size of the casting model, which greatly reduces the waste of molten aluminum and is highly practical. In addition, the base 22 and the measuring cylinder 21 are fixedly connected by threads, which greatly facilitates the cleaning of the interior of the measuring cylinder 21 at a later time.

[0045] As an embodiment of the present invention, Figure 3 and Figure 5As shown, the opening and closing assembly 5 includes a valve housing 51, a guide block 52, a slide cylinder 53, a slide rod 54, a stop block 55, and a second spring 56. The left and right outer surfaces of the measuring cylinder 21 are symmetrically fixedly connected to the valve housing 51 near the bottom end, and the left end surface of the valve housing 51 near the left side is fixedly connected to the ladle body 1. The left and right outer surfaces of the measuring cylinder 21 are symmetrically fixedly connected to the position above the valve housing 51, and the bottom end surface of the transmission plate 33 is fixedly connected to the slide cylinder 53 near the left and right ends. The opening and closing assembly 5 also includes a slide rod 54, a stop block 55, and a second spring 56. The inner surface of the slide cylinder 53 is slidably connected to the slide rod 54, and the two are T-shaped structural designs that match each other. The bottom end of the slide rod 54 passes through the guide block 52 and extends into the interior of the valve housing 51, and it is connected to the guide block 5 2. The valve housing 51 is slidably connected, and the outer surface of the slide rod 54 is fixedly connected with a stop block 55 near the upper end surface of the valve housing 51, and the outer surface of the slide rod 54 is sleeved with a spring 2 56 near the position above the stop block 55, and the top end of the spring 2 56 is fixedly connected to the guide block 52. The inside of the valve housing 51 near the right side is slidably connected with a valve core 1 6, and the top end of the valve core 1 6 is fixedly connected to the slide rod 54, and the inside of the valve core 1 6 near the bottom is horizontally penetrated by a valve hole 1 61, and the outer surfaces of the left and right sides of the valve housing 51 are penetrated by connecting grooves 62 at positions corresponding to the through groove 24. The inside of the valve housing 51 near the left side is slidably connected with a valve core 2 7, and the top end of the valve core 2 7 is fixedly connected to the slide rod 54, and the inside of the valve core 2 7 is provided with a valve hole 2 71 at a position corresponding to the through groove 24.

[0046] When the cam 53 is in engagement with the spring 56, the stop block 55 is driven downwards to close the valve housing 51. The position of the slide rod 54 does not change at first. When the slide rod 53 and the slide rod 54 are engaged with each other at the T-shaped portion, the slide rod 53 continues to move upwards, which can drive the slide rod 54 to move upwards, thereby driving the valve core 1 6 and the valve core 2 7 fixed at the bottom end of the slide rod 54 to move upwards. When the valve core 2 7 moves upwards, the valve hole 2 71 and the connecting groove 62 are offset from each other, causing the left opening and closing assembly 5 to close, stopping the injection of molten aluminum into the measuring cylinder 21. At the same time, when the valve core 1 6 moves upwards, it can gradually drive the valve hole 1 61 and the connecting groove 62 to overlap with each other, thereby opening the right opening and closing assembly 5, allowing the molten aluminum in the measuring cylinder 21 to flow out smoothly from the right side for casting operation. The casting operation can be completed without consuming a lot of manpower and material resources to dump the ladle body 1, thereby greatly improving the casting efficiency.

[0047] As an embodiment of the present invention, Figure 3 As shown, the valve hole 1 61 and the valve hole 2 71 are both designed to be inclined toward the lower right corner with respect to the through slot 2 24 .

[0048] By adopting the above technical solution, it is ensured that the molten aluminum can flow smoothly from the left side to the right side of the casting mechanism 2, thereby reducing the accumulation of molten aluminum at the bottom of the casting mechanism 2 during the casting process.

[0049] As an embodiment of the present invention, as shown in the figure, a pouring nozzle 8 is fixedly connected to the right outer surface of the valve housing 51 near the right side, corresponding to the communicating groove 62, and the pouring nozzle 8 is designed to be inclined toward the lower right corner;

[0050] A baffle is fixedly connected to the bottom of the inner surface of the pouring nozzle 8 near the middle, and a filter screen 81 is placed on the inner surface near the left side of the baffle.

[0051] By adopting the above technical solution, when the right valve hole 61 and the connecting groove 62 overlap with each other, the right opening and closing component 5 is opened, so that the aluminum liquid inside the measuring cylinder 21 can smoothly flow into the filter screen 81 from the right side. After filtering out some solid impurities through the filter screen 81, it flows to the right through the nozzle 8 into the casting sand box, completing the casting operation. The filter screen 81 is clamped above the nozzle 8 by the baffle, which makes it convenient for the user to clean the solid impurities inside the filter screen 81.

[0052] Working principle: When working, open the insulation cover 12, pour the molten aluminum into the ladle body 1, close the insulation cover 12 to reduce the heat loss of the molten aluminum, and at the same time control the internal heating wire to keep the molten aluminum inside the ladle body 1 warm. Fix the lifting ear 11 through the lifting device, move the ladle body 1 as a whole to the casting mold, and align the nozzle 8 with the casting port, control the drive assembly 3 to work, in the initial state, the slider 42 is located at the bottom of the measuring cylinder 21, control the hydraulic push rod 32 to contract, drive the transmission plate 33 to move upward, thereby driving the fixed cylinder 34 to move upward, since the transmission rod 35 is threadedly connected to the fixed cylinder 34, it will drive the transmission rod 35 to move upward, and when the transmission rod 35 moves upward to engage with the limit rod 41, continuing to move upward will drive the limit rod 41 to move upward. The positioning rod 41 moves upward, thereby driving the slider 42 to move upward along the slide groove 23. In the initial state, the opening and closing assembly 5 close to the left side of the measuring cylinder 21 is in the open state, and the right opening and closing assembly 5 is in the closed state. When the transmission plate 33 moves upward, it can drive the slide cylinder 53 to move upward. Under the action of the spring 2 56, it can drive the stop block 55 downward and tightly fit the valve housing 51. The position of the slide rod 54 does not change at first. At this time, the left opening and closing assembly 5 is still in the open state. Under the action of pressure, the aluminum liquid inside the ladle body 1 will enter the measuring cylinder 21 through the through groove 1 13 and the left opening and closing assembly 5. By fixing the filter screen on the left side of the through groove 13, it can effectively prevent solid impurities in the aluminum liquid from being injected into the sand box through the casting mechanism 2. Under the action of the internal electric heating wire, the aluminum liquid can be kept warm to prevent it from solidifying quickly. When the slide cylinder 53 and the slide rod 54 are engaged with each other at the T-shaped position, the slide cylinder 53 continues to move upward, which can drive the slide rod 54 to move upward, thereby driving the valve core 1 6 and the valve core 2 7 fixed at the bottom end of the slide rod 54 to move upward. When the valve core 2 7 moves upward, the valve hole 2 71 and the connecting groove 62 will be offset from each other, causing the left opening and closing component 5 to close, and the injection of aluminum liquid into the measuring cylinder 21 will be stopped. At the same time, when the valve core 1 6 moves upward, it can gradually drive the valve hole 1 61 and the connecting groove 62 to overlap with each other, and the right opening and closing component 5 will be opened, so that the aluminum liquid inside the measuring cylinder 21 can smoothly flow into the filter screen 81 from the right side, and some of the liquid will be filtered out through the filter screen 81. After the solid impurities have passed through the pouring nozzle 8, they flow to the right into the casting sand box to complete the casting operation. The filter screen 81 is clamped above the pouring nozzle 8 by the blocking bar, which makes it convenient for the user to clean the solid impurities inside the filter screen 81. The user can adjust the distance that the transmission rod 35 extends into the interior of the measuring cylinder 21 by rotating the transmission rod 35 to adjust the position of the limit rod 41 inside the limit groove 4. When the position of the transmission rod 35 is adjusted downward, the top of the limit rod 41 is located near the top of the limit groove 4. When the hydraulic push rod 32 contracts at a uniform speed to drive the transmission rod 35 to move upward, the time for the limit rod 41 to engage with each other at the T-shaped portion of the limit groove 4 is extended. Before the left opening and closing assembly 5 is closed, the distance that the transmission rod 35 drives the slider 42 to move upward becomes shorter.As a result, less molten aluminum enters the measuring cylinder 21. On the contrary, if the transmission rod 35 is adjusted upward, more molten aluminum enters the measuring cylinder 21. That is, the user can set the volume of the casting molten aluminum according to the size of the casting model, which greatly reduces the waste of molten aluminum.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
