Description

Technical Field

[0001] The utility model relates to the technical field of smelting furnace equipment, in particular to a smelting furnace for casting aluminum parts. Background Art

[0002] A smelting furnace is a device used to heat and melt metal ores or other raw materials to extract metals. This equipment is commonly used in metal smelting and alchemy industries. A smelting furnace can convert solid metals into liquid form through high temperatures, which can then be extracted, separated and refined through various methods;

[0003] At present, common crucibles usually include a furnace body and a crucible. When a smelting furnace heats and melts aluminum blocks or other metal blocks, the aluminum blocks or other metal blocks are usually placed in the crucible, and then the crucible is inserted into the furnace cavity. The furnace body is controlled to heat the crucible, thereby heating the metal block in the crucible to form a solid metal into a liquid state. After the solid metal is converted into a liquid state, the crucible is taken out of the furnace cavity with pliers, and the liquid metal is taken out of the furnace cavity to discharge the liquid metal. This discharge method has the following defects in actual operation:

[0004] 1. Use pliers to fix the crucible, take the crucible out of the furnace chamber, and then pour out the liquid metal. The overall operation is more troublesome and reduces the efficiency of material discharge;

[0005] 2. When the crucible is taken out of the furnace chamber and the liquid metal is poured out, the temperature of the crucible is relatively high. If the pliers are not stable in holding the crucible and the crucible falls, the liquid metal in the crucible may splash out and cause harm to the staff;

[0006] Therefore, the present application proposes a melting furnace for aluminum casting. Utility Model Content

[0033] When the aluminum block is smelted, the aluminum block is fed into the crucible 4, the furnace body 2 is controlled to be opened, and the furnace body 2 is operated to heat the crucible 4, thereby heating the aluminum block in the crucible 4, so that the aluminum block melts and becomes liquid. Through the design of the rotating shaft 22 and the driving member 3, when the aluminum block in the crucible 4 is liquid and the material is unloaded, the furnace cover 5 is rotated on the furnace body 2 to one side of the furnace body 2, and the furnace cover 5 is positioned by the positioning member 6.

[0036] In this embodiment, the driving member 3 includes a worm wheel 31 coaxially fixed to the rotating shaft 22, and a worm 32 meshing with the worm wheel 31 is rotatably installed on the supporting frame 1. When in use, a force is applied to the worm 32 to make it rotate on the supporting frame 1, and the rotating shaft 22 can be driven to rotate on the supporting frame 1 through the worm wheel 31. The operation is simple. Since the meshing of the worm wheel 31 and the worm 32 is self-locking, the worm wheel 31 will not rotate when the worm 32 is not rotated, so that the position of the furnace body 2 can be fixed, which is convenient for use.

[0037] In this embodiment, the positioning member 6 includes a slide rail 61 fixedly installed on one side of the furnace body 2, a fixing rod 62 is fixedly installed on the side of the furnace cover 5 close to the slide rail 61, a positioning rod 63 is slidably installed on the slide rail 61, and a positioning ring 64 that can be sleeved on the outside of the fixing rod 62 is fixedly installed on the end of the positioning rod 63. When in use, the furnace cover 5 is rotated on the furnace body 2 to one side of the furnace body 2. When positioning the furnace cover 5, the positioning rod 63 is slid on the slide rail 61, so that the positioning ring 64 is sleeved on the outside of the fixing rod 62, and the furnace cover 5 can be positioned. The operation is simple, and through the design of the fixing rod 62, a force is applied to the fixing rod 62, so that the furnace cover 5 can be rotated on the furnace body 2, which is convenient for rotating the furnace cover 5.

[0038] In this embodiment, a guide groove 41 is provided on the top of the crucible 4 and on one side away from the hinge 51. Through the design of the guide groove 41, the opening end of the crucible 4 is tilted downward, and the liquid metal in the crucible 4 is drained to achieve a guiding effect.

[0039] Embodiment 3

[0040] like Figure 1-Figure 4 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0043] In this embodiment, a limiting plate 721 is fixedly installed on the top of the fixed block 72. When the fixed block 72 contacts the crucible 4, the limiting plate 721 fits against the top of the crucible 4. Through the design of the limiting plate 721, when the fixed block 72 contacts the crucible 4, the limiting plate 721 fits against the top of the crucible 4, thereby further improving the limiting effect on the crucible 4 and avoiding the situation where the open end of the crucible 4 tilts downward and the crucible 4 slips out of the furnace chamber 21 when the liquid metal in the crucible 4 is poured out.

The operation is simple and the unloading efficiency is improved. At the same time, it is effectively avoided that the pliers are not stable to clamp the crucible 4, resulting in the crucible 4 falling, thereby effectively avoiding the situation that the liquid metal in the crucible 4 splashes and causes injuries to the staff; through the design of the guide groove 41, the opening end of the crucible 4 is tilted downward, and the liquid metal is guided when the liquid metal in the crucible 4 is poured out for unloading;

[0047] By arranging the crucible 4 to be inserted into the furnace chamber 21, it is convenient to install and disassemble the crucible 4, thereby facilitating the cleaning of the crucible 4 at a later time. The positioning effect of the crucible 4 is achieved through the design of the fixing mechanism 7. Through the design of the limiting plate 721, when the fixing block 72 contacts the crucible 4, the limiting plate 721 fits with the top of the crucible 4, further improving the limiting effect of the crucible 4, and avoiding the situation where the open end of the crucible 4 tilts downward and the crucible 4 slips out of the furnace chamber 21 when the liquid metal in the crucible 4 is poured out.
