Description

Technical Field

[0001] The invention relates to the technical field of casting devices, and in particular to a casting device for a tubular aluminum alloy part. Background Art

[0002] Cast aluminum alloy is an aluminum alloy that is obtained by filling the mold with molten metal to obtain various shapes of parts. It has the advantages of low density, high specific strength, good corrosion resistance and casting processability, and little restriction on part structure design. It is divided into medium-strength alloys based on Al-Si and Al-Si-Mg-Cu; high-strength alloys based on Al-Cu; corrosion-resistant alloys based on Al-Mg; heat-resistant alloys based on Al-Re. Most of them need heat treatment to achieve the purpose of strengthening the alloy, eliminating internal stress of the casting, stabilizing the organization and part size, etc.

[0003] The existing patent with the publication number of "CN212419623U" is named a tubular aluminum alloy casting device. By setting a filter box, when the aluminum alloy solution flows from the fixed plate into the filter box, the foam and ceramic filter screens are used to block, capture and absorb to effectively remove hydrogenated inclusions and other non-metallic inclusions. Large impurities will be alluvial to the chip groove opened between the inner wall of the filter box and the foam ceramic filter screen. After filtration, the aluminum alloy solution with higher purity will flow into the mold through the positioning pouring head under the action of the solution pressure, thereby improving the purity and uniformity of the casting product and reducing the product scrap rate. The inventor believes that when the metal solution is heated and melted at high temperature, it needs to be crushed to improve the high-temperature melting efficiency. At the same time, it is difficult to filter out impurities when the molten aluminum metal solution is filtered through the filter cylinder in the "CN212419623U" patent, which affects the quality of the cast product. Therefore, a tubular aluminum alloy casting device is needed. Summary of the invention

[0037] As a preferred implementation in this embodiment, refer to the attached Fig.11 The opening and closing linkage assembly also includes an inclined plate 24 fixedly connected to the upper surface of the driving plate 8, a linkage inclined plate 19 is fixedly connected to one side of the upper casting mold 18, and a roller 55 is rotatably connected to the inner wall of the linkage inclined plate 19, the surface of the roller 55 contacts the surface of the inclined plate 24, and one side of the driving plate 8 is fixedly connected to one side of the rack 63.

[0038] By providing the inclined plate 24 , the roller 55 is driven to move along the inclined surface of the inclined plate 24 , thereby increasing the height of the linkage inclined plate 19 and the upper casting mold 18 , and the upper casting mold 18 increases in height along the plurality of guide columns 10 .

[0039] The working principle of the present invention is as follows: a tubular aluminum alloy casting device, in the initial state, aluminum alloy raw materials are added to the heating furnace 2 through the feed box 4, in this process, the reduction motor 5 is started, the reduction motor 5 drives the driving cylinder 11 to rotate, the driving cylinder 11 drives the linkage shaft 15 and the first bevel gear 37 located on the driving cylinder 11 to rotate, the first bevel gear 37 drives the second bevel gear 36 to rotate, the second bevel gear 36 drives the first turntable 40 to rotate through the driving shaft 39, the first turntable 40 drives the second turntable 51 to rotate through the cooperation of the first groove 49 and the convex ball 52, the second turntable 51 rotates through the cooperation of the convex ball 52 and the second groove 53, drives the third turntable 54 and the second turntable 51 to reverse, at this time drives the first crushing roller 13 and the second crushing roller 13 to rotate. The crushing roller 14 reverses to break the material and accelerate the melting efficiency. At this time, the collecting box 16 also rotates, but the crushed material is small and will fall directly into the bottom of the heating furnace 2. The combustion heating chamber 35 is started to heat and melt the aluminum alloy. During the melting process, the aluminum alloy raw material continues to be added through the discharge box 4 until the molten solution touches the surface of the collecting box 16. The melting point temperature of the collecting box 16 and the rolling ball 32 is greater than the melting point temperature of the aluminum alloy and will not melt. One end of the collecting box 16 is supported by the rolling ball 32, and the rolling ball 32 is located in the horizontal guide groove 47. During the rotation process, when the rolling ball 32 moves along the guide of the rising guide groove 33, it drives the linkage shaft 15 to slide and rise in the driving cylinder 11. In this process, the linkage shaft 15 drives the friction plate 26 to rise. The friction plate 26 rises and contacts with the surface of the friction roller 27 by friction, driving the friction roller 27 to rotate. The rotation of the friction roller 27 drives the collecting tank 31 to rotate, and the borax powder in the discharge box 30 is sent into the molten liquid in the heating furnace 2. Borax can remove impurities in the metal during processing. Since the temperature of the liquid after the aluminum alloy is melted is lower, the density of impurities is lower than that of the metal, and they float on its surface, easily forming a metal oxide layer. During the rotation of the collecting box 16, the impurity oxide layer is collected on the second inclined plate 43 through the scraping bevel 42. When the rolling ball 32 moves into the concave guide groove 34, the concave guide groove 34 is tilted, driving the collecting box 16 and the connecting plate 46 to rotate, and the impurities are sent out through the slag discharge hole 41, and then through the concave guide The slag is sent into the waste slag box 3 through the groove 34 and the sliding hole 48 for collection. In this process, the spur gear 56 rotates to always keep the rack 63 on the side close to the heating furnace 2. When the molten impurities are cleaned and casting is required, the valve 22 is opened, and the molten liquid in the heating furnace 2 passes through the Z-shaped drop pipe 6 and the gathering cone 66 and enters the lower casting mold 21. At this time, it is shaped through the cavity of the forming cavity 65. The hollow shaping column 64 ensures the hollowness of the tubular aluminum material. After cooling, the reduction motor 5 can be started to reverse, and finally the spur gear 56 is driven to reverse through the transmission of the belt 7. The spur gear 56 reverses and drives the rack 63 to slide along the guide plate 9 away from the heating furnace 2. At this time, the driving plate 8 slides away from the heating furnace 2, so that the roller 55 rises under the action of the surface of the inclined plate 24.The upper casting mold 18 is driven to slide upward on the surface of the guide column 10. At this time, the upper casting mold 18 is separated from the lower casting mold 21. The driving plate 8 drives the hollow shaping column 64 to be pulled out from the lower casting mold 21 and the upper casting mold 18 to achieve the shaping operation. The shaping pipe in the lower casting mold 21 can be taken out. By means of the above structure, the aluminum alloy raw material is crushed to improve the high-temperature melting efficiency, and impurities are removed after melting, which is convenient for subsequent mold opening and material taking.
