Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary production equipment for lost foam molds, in particular to a mechanism for cleaning aluminum slag in lost foam molds. Background Art

[0002] The lost foam casting process is a relatively new casting technology in the foundry industry. It is widely used in the foundry industry because of its advantages such as high precision and environmental protection.

[0003] At present, each product needs to be made using a lost foam mold. When producing molds made of aluminum alloy, it is not convenient to clean the aluminum slag at the bottom of the furnace during the slag removal process during the smelting of the aluminum alloy in the smelting furnace, that is, the slag removal is not thorough. Therefore, when the aluminum alloy is subsequently water-cast into a mold, slag inclusions will appear on the surface and inside of the mold, which will affect the quality of the mold surface and the accuracy of the mold. In addition, when there are many slag inclusions, the missing parts of the aluminum alloy need to be welded and then reprocessed, but the aluminum alloy is very easy to deform during the welding process, which will cause dimensional deviations in the mold or even scrap it, thereby affecting production efficiency and increasing production costs. Therefore, there are still shortcomings and deficiencies in the prior art. Utility Model Content

[0004] The utility model aims to provide a mechanism for cleaning aluminum slag in a lost foam mold to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above problems, the technical solution adopted by the utility model is:

[0006] A mechanism for cleaning aluminum slag in a lost foam mold comprises a horizontally arranged transverse frame, a vertically distributed connecting rod assembly is fixedly connected to the middle position of the transverse frame, a fixing plate coaxially arranged with the connecting rod assembly is fixedly connected to the bottom end of the connecting rod assembly, a through hole is vertically opened on the fixing plate, and a shell structure coaxially arranged with the fixing plate and having a cavity is fixedly connected to the bottom surface of the fixing plate, both ends of the shell structure are opened, and the shell structure is funnel-shaped with a narrow top and a wide bottom.

[0007] Furthermore, the connecting rod assembly includes a threaded tube and a connecting rod coaxially arranged, the connecting rod and the fixed plate are coaxially arranged, and one end of the connecting rod is fixedly connected to the fixed plate, and the other end of the connecting rod is threadedly connected to the threaded tube, and the end of the threaded tube away from the connecting rod is fixedly connected to the transverse frame.

[0008] Furthermore, first reinforcing rods are fixedly connected between both sides of the threaded tube and the transverse frame, and second reinforcing rods are fixedly connected between both sides of the connecting rod and the fixed plate.

[0009] Furthermore, the horizontal frame includes a crossbar distributed horizontally. The middle position of the crossbar is fixedly connected to the link assembly. Both ends of the crossbar are fixedly connected with grip bars perpendicular to the crossbar, and the middle position of the grip bar is connected to the crossbar.

[0010] Furthermore, the housing structure, the fixing plate, the link assembly, the crossbar and the grip bar are all made of steel. One end of the crossbar is fixedly connected with a grip. A heat insulation sleeve is sleeved and installed on the grip.

[0011] Furthermore, the grip is coaxially arranged with the crossbar. A stop bar perpendicular to the grip and passing through the grip is threadedly connected to the end of the grip away from the crossbar. The heat insulation sleeve is located on the side of the stop bar close to the crossbar and is slidably connected to the grip.

[0012] Adopting the above technical solution, the beneficial effects of the present utility model are as follows:

[0013] When the present utility model is in use, when the aluminum alloy water in the melting furnace reaches 680 degrees and starts to boil, after the horizontal frame is erected at the furnace mouth position of the melting furnace, the housing structure can be completely immersed in the aluminum alloy water in the melting furnace, and there is a certain distance between the bottom opening of the housing structure and the furnace bottom of the melting furnace, and there is also a certain distance between the outer wall of the housing structure and the inner wall of the melting furnace. At this time, during the upward boiling process of the aluminum alloy water, under the blocking action of the housing structure and the fixing plate, a part of the aluminum alloy water can flow back to impact the aluminum slag at the furnace bottom position of the melting furnace, so that the aluminum slag at the furnace bottom can be turned up to the liquid level position of the aluminum alloy water. At the same time, the aluminum slag in the housing structure can be turned up to the liquid level position of the aluminum alloy water through the through hole, thereby facilitating the operator to use a fishing tool to clean the aluminum slag at the furnace bottom of the melting furnace, making the slag removal more thorough, so as to improve the cleanliness of the aluminum alloy water. In this way, when the aluminum alloy water is subsequently cast into a mold, on the one hand, the appearance and internal slag inclusion of the mold can be reduced to improve the surface quality and accuracy of the mold; on the other hand, the situation where the mold needs to be welded and then reprocessed can be reduced, thereby reducing the probability of the mold deforming, improving the production efficiency, and reducing the production cost.

Detailed implementation manners

[0018] To make the objectives, technical solutions and beneficial effects of the present utility model clearer, the following further describes the implementation manners of the present utility model in detail with reference to the accompanying drawings.

[0019] As Figures 1 to 3 shown, the present utility model provides a mechanism for cleaning aluminum slag in a lost foam mold, including a horizontally arranged transverse frame 2. A vertically distributed connecting rod assembly 3 is fixedly connected to the middle position of the transverse frame 2. The bottom end of the connecting rod assembly 3 is fixedly connected with a fixing plate 4 arranged coaxially with the connecting rod assembly 3. A through hole 41 is vertically formed in the fixing plate 4. Specifically, the number of the through holes 41 is two, and the two through holes 41 are symmetrically distributed on both sides of the fixing plate 4. And a housing structure 1 having a cavity and arranged coaxially with the fixing plate 4 is fixedly connected to the bottom surface of the fixing plate 4. Both ends of the housing structure 1 are open, and the housing structure 1 is in a funnel shape with a narrow top and a wide bottom.

[0020] Specifically, during use, when the aluminum alloy liquid in the melting furnace 8 starts to churn at 680 degrees, after the transverse frame 2 is erected at the furnace mouth position of the melting furnace 8, the housing structure 1 can be completely immersed in the aluminum alloy liquid in the melting furnace 8, and there is a certain distance between the bottom opening of the housing structure 1 and the furnace bottom of the melting furnace 8. There is also a certain distance between the outer wall of the housing structure 1 and the inner wall of the melting furnace 8. At this time, during the upward churning process of the aluminum alloy liquid, under the blocking action of the housing structure 1 and the fixing plate 4, a part of the aluminum alloy liquid can flow back to the position at the furnace bottom of the melting furnace 8 to impact the aluminum slag, so that the aluminum slag at the furnace bottom can be churned to the liquid surface position of the aluminum alloy liquid. At the same time, the aluminum slag in the housing structure 1 can be churned to the liquid surface position of the aluminum alloy liquid through the through hole 41, so that it is convenient for the operator to use a fishing tool to clean the aluminum slag at the furnace bottom of the melting furnace 8, making the slag removal more thorough, so as to improve the cleanliness of the aluminum alloy liquid. In this way, when the aluminum alloy liquid is subsequently cast into a mold, on the one hand, the appearance and internal slag inclusion of the mold can be reduced to improve the surface quality and precision of the mold; on the other hand, the situation where the mold needs to be welded and then reprocessed can be reduced, thereby reducing the probability of mold deformation, improving production efficiency, and reducing production costs.

[0021] In addition, after the housing structure 1 is immersed in the aluminum alloy water for a period of time, the housing structure 1 can be taken out of the melting furnace 8, and then a slag removing agent that can agglomerate aluminum slag in the prior art is added to the melting furnace 8. After the aluminum slag agglomerates into blocks, the cleaning can be started, which is more convenient for slag removal.

[0022] The specific setting method of the connecting rod assembly 3 is as follows: As Figures 1 to 3 shown, the connecting rod assembly 3 includes a threaded tube 31 and a connecting rod 32 arranged coaxially. The connecting rod 32 is arranged coaxially with the fixed plate 4, and one end of the connecting rod 32 is fixedly connected to the fixed plate 4, and the other end of the connecting rod 32 is threadedly connected to the threaded tube 31. Specifically, only the end of the connecting rod 32 close to the threaded tube 31 is provided with an external thread to be threadedly connected to the threaded tube 31, and the rest of the connecting rod 32 is a smooth rod; the end of the threaded tube 31 away from the connecting rod 32 is fixedly connected to the transverse frame 2. Specifically, by rotating the connecting rod 32, the distance between the transverse frame 2 and the housing structure 1 can be adjusted. In this way, before use, the position of the housing structure 1 can be adjusted according to the depth of the melting furnace 8 to be applicable to melting furnaces 8 with different furnace depths.

[0023] Furthermore, as Figures 1 to 3 shown, first reinforcing rods 33 are fixedly connected between both sides of the threaded tube 31 and the transverse frame 2. The first reinforcing rods 33 can improve the connection strength between the threaded tube 31 and the transverse frame 2; secondly, second reinforcing rods 34 are fixedly connected between both sides of the connecting rod 32 and the fixed plate 4. The second reinforcing rods 34 can improve the connection strength between the connecting rod 32 and the fixed plate 4.

[0024] The specific setting method of the transverse frame 2 is as follows: As Figures 1 to 3 shown, the transverse frame 2 includes a cross bar 21 distributed horizontally. The middle position of the cross bar 21 is fixedly connected to the connecting rod assembly 3. Both ends of the cross bar 21 are fixedly connected with grip bars 22 perpendicular to the cross bar 21. The middle position of the grip bar 22 is connected to the cross bar 21. Specifically, during use, the operator can easily place the transverse frame 2 at the furnace mouth position of the melting furnace 8 by holding the grip bars 22.

[0025] To ensure that the present utility model will not deform during use, therefore, the housing structure 1, the fixed plate 4, the connecting rod assembly 3, the cross bar 21 and the grip bars 22 are all made of steel material, that is, the steel material will not deform in the aluminum alloy water at 680 degrees; secondly, when the housing structure 1 is taken out of the melting furnace 8, to prevent the operator from being scalded, therefore, as Figures 1 to 3 shown, one end of the cross bar 21 is fixedly connected with a grip 5, and a heat insulation sleeve 6 is sleeved and installed on the grip 5. Specifically, the heat insulation sleeve 6 is made of a heat insulation material in the prior art; during use, the operator can take out the housing structure 1 from the melting furnace 8 by holding the heat insulation sleeve 6 to prevent the operator from being scalded.

[0026] Furthermore, as Figures 1 to 3 shown, the grip 5 is coaxially arranged with the cross bar 21, and a stop bar 7 perpendicular to the grip 5 and penetrating the grip 5 is threadedly connected to one end of the grip 5 away from the cross bar 21. Specifically, the stop bar 7 is a threaded rod. Since the stop bar 7 is threadedly connected to the grip 5, it is convenient to disassemble and assemble the stop bar 7 on the grip 5. In addition, the heat insulation sleeve 6 is located on the side of the stop bar 7 close to the cross bar 21 and is slidably connected to the grip 5. Specifically, during use, when the stop bar 7 is removed, the heat insulation sleeve 6 can be removed. After the heat insulation sleeve 6 is sleeved on the grip 5, the position of the heat insulation sleeve 6 can be restricted under the action of the stop bar 7 and the grip 22, which is convenient for disassembling and assembling the heat insulation sleeve 6 on the grip 5.
