[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] See also Figure 1 - Figure 4 A vacuum melting furnace for easy material removal comprises a furnace body 1 and a furnace cover 2, wherein a cover groove 101 is provided at one end of the furnace body 1 close to the furnace cover 2, the furnace cover 2 is slidably connected to the cover groove 101, a plurality of fixing bars 3 are fixedly connected to the inner wall of the cover groove 101 close to one end of the furnace cover 2, the plurality of fixing bars 3 are annularly distributed along the cover groove 101, a plurality of connecting bars 4 matching the plurality of fixing bars 3 are fixedly connected to the outer wall of the furnace cover 2, and the plurality of connecting bars 4 are respectively located on one side of the plurality of fixing bars 3 close to the cover groove 101, and are slidably connected to the cover groove 101, and the distance between two adjacent fixing bars 3 is not less than the length of the connecting bars 4, and a hand pull ring 5 is fixedly connected to the side of the furnace cover 2 away from the furnace body 1.

[0023] like Figure 1 - Figure 4 As shown, the vacuum melting furnace for easy material removal in the utility model is similar to the existing vacuum melting furnace for easy material removal, such as an aluminum cavity vacuum melting furnace disclosed in the patent with publication number CN217210306U. The main improvement of the utility model is that the user can more conveniently open the furnace cover 2 of the vacuum melting furnace to facilitate the material removal operation from the furnace body 1. Figures 1 to 4 As shown, when the vacuum melting furnace for easy material removal in the utility model is in use, the furnace cover 2 is attached to the cover groove 101 through the hand pull ring 5, and multiple connecting strips 4 are placed between the multiple fixing strips 3. Then, the furnace cover 2 is rotated, and the multiple connecting strips 4 can be slid into between the multiple fixing strips 3 and the cover groove 101, so as to cooperate to complete the fixation of the furnace cover 2. When the furnace cover 2 needs to be opened, the furnace cover 2 is rotated in the opposite direction through the hand pull ring 5, and the position between the connecting strips 4 and the fixing strips 3 is misaligned, so that the furnace cover 2 can be taken out of the cover groove 101, and the furnace cover 2 can be opened smoothly. The operation is simple and quick, and it is convenient to quickly open the furnace cover 2 when removing materials.

[0024] like Figure 1 - Figure 4As shown, the furnace cover 2 is rotatably connected to a connecting arm 6 at one side away from the furnace body 1, and the other end of the connecting arm 6 is rotatably connected to the furnace body 1. By rotating between the connecting arm 6 and the furnace body 1, the furnace cover 2 can be conveniently opened from the cover groove 101 to keep the furnace cover 2 connected to the furnace body 1, thereby preventing the furnace cover 2 from falling off.

[0025] like Figure 1 - Figure 4 As shown, a T-shaped rotating shaft 7 is connected to the side of the furnace cover 2 away from the furnace body 1, and a thinner end of the T-shaped rotating shaft 7 passes through the connecting arm 6 and is fixedly connected to the furnace cover 2, and the T-shaped rotating shaft 7 is located at the center of the furnace cover 2. When the furnace cover 2 is rotated, the T-shaped rotating shaft 7 at the center rotates on the connecting arm 6, so that the furnace cover 2 is opened or closed by the rotation.

[0026] like Figure 1 - Figure 4 As shown, the outer wall of the furnace body 1 near the furnace cover 2 is fixedly connected with a connecting block 8, and a turning groove 801 is provided on the side of the connecting block 8 away from the furnace body 1. The inner wall of the turning groove 801 is rotatably connected with a turning block 9 through a rotating shaft, and one side of the turning block 9 is fixedly connected to the end of the connecting arm 6 away from the furnace cover 2. When the furnace cover 2 is moved through the connecting arm 6, the turning block 9 rotates in the turning groove 801, so that the furnace cover 2 is turned over through the connecting arm 6 and kept at the same horizontal line with the cover groove 101, so as to facilitate the opening or closing operation of the furnace cover 2.

[0027] like Figure 1 - Figure 4 As shown, the hand pull ring 5 is located on the side of the connecting arm 6 away from the flip block 9. The hand pull ring 5 is arranged on the side of the connecting arm 6 away from the flip block 9, so that when the furnace cover 2 is controlled by the hand pull ring 5, the hand will not collide with the connecting arm 6.

[0028] like Figure 2 and Figure 3 As shown, a sealing gasket is provided between the furnace cover 2 and the cover groove 101. The sealing gasket is provided between the furnace cover 2 and the cover groove 101 to further improve the airtightness of the connection between the furnace cover 2 and the cover groove 101, and to prevent external gas from entering the furnace body 1 during vacuuming.

[0029] like Figure 1 - Figure 4 As shown, one side of the plurality of fixing bars 3 in the clockwise direction is fixedly connected with a stopper 10. When the furnace cover 2 is connected to the cover groove 101 by rotation, after the connecting bar 4 slides into between the fixing bar 3 and the cover groove 101, the stopper 10 can prevent the connecting bar 4 from continuing to slide and prevent the connecting bar 4 from sliding out from between the fixing bar 3 and the cover groove 101.

[0030] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
