[0029] A stirring assembly 12, the top wall of the melting box 9 is fixedly connected with a motor 121, and the output shaft of the motor 121 is drivingly connected with a driving shaft 122, and the lower end of the driving shaft 122 is fixedly connected with a stirring blade 123, and the driving shaft 122 is driven to rotate by the motor 121, so that the stirring blade 123 rotates to stir the metal solution;

[0030] The linkage stirring assembly 13, the outer ring of the driving shaft 122 is movably sleeved with a linkage shaft 131, and the linkage shaft 131 and the driving shaft 122 are connected to each other through a bevel gear set 134, and the lower end of the linkage shaft 131 is fixedly connected with a stirring blade 133, and the secondary stirring ensures a better melting effect of the metal solution;

[0031] In the multi-directional stirring assembly 14, a rotating shaft 141 is inserted and connected to the interior of the second stirring blade 133 through a bearing, and a disc 142 is fixedly connected to the top of the rotating shaft 141, and the upper end of the rotating shaft 141 and the disc 142 move inside the annular groove 143 reserved at the top of the melting box 9, so as to ensure the stability of the rotating shaft 141 during its own circular motion when the second stirring blade 133 rotates, and at the same time does not affect the self-rotation of the rotating shaft 141. The outer ring of the rotating shaft 141 is fixedly sleeved with a gear 146, and the gear 146 is meshed with a tooth block 145 fixedly connected to the inner wall of the notch 144 set at the top of the melting box 9, so as to ensure that the rotating shaft 141 can realize its own rotation to drive the rotation of the third stirring blade 147 when the rotating shaft 141 moves in an annular motion, and the notch 144 is connected to the lower end of the annular groove 143, so as to ensure that the self-rotation and annular motion of the rotating shaft 141 are not affected, and the outer wall of the rotating shaft 141 is fixedly connected to the third stirring blade 147, so as to improve the overall melting efficiency of the metal solution.

[0032] The stirring blade 123 is in a "U" shape, the stirring blade 133 is in an "N" shape, and the stirring blade 123 and the stirring blade 133 are arranged opposite to each other up and down, and the staggered rotation of the stirring blade 123 and the stirring blade 133 is not affected. The stirring blade 123 and the stirring blade 133 are staggered, and the rotation of the stirring blade 123 and the stirring blade 133 is not affected. In this way, the staggered rotation of the two groups of stirring blades can achieve uniform mixing of the metal solution in the melting process and ensure the melting effect.

[0033] A through hole 132 is opened inside the linkage shaft 131, and the inner wall of the through hole 132 is a smooth surface, and the inner wall of the through hole 132 is in contact with and rotationally connected to the outer ring of the drive shaft 122, so that when the drive shaft 122 inserted inside the linkage shaft 131 rotates, the linkage shaft 131 is driven to rotate through the transmission of the bevel gear set 134, and the wrong direction rotation of the drive shaft 122 and the linkage shaft 131 is not affected.

[0034] The bevel gear set 134 is composed of three meshing bevel gears, and the upper and lower symmetrical and transversely arranged bevel gears are fixedly sleeved on the outer rings of the driving shaft 122 and the linkage shaft 131 respectively, and the remaining vertically arranged bevel gear is meshed and connected with the two transversely and symmetrically arranged bevel gears, and the inner ring of the vertically arranged bevel gear is inserted with an auxiliary shaft 135, and the end of the auxiliary shaft 135 is fixedly connected to the inner wall of the protection frame 136. In this way, when the driving shaft 122 rotates, the transmission of the three sets of meshing bevel gears can drive the linkage shaft 131 to rotate in the opposite direction, and the protection frame 136 ensures that the rotation of the bevel gear set 134 is not affected by the outside world.

[0035] The protection frame 136 is sleeved on the outer wall of the bevel gear set 134, and the drive shaft 122 and the linkage shaft 131 are inserted into the protection frame 136. The drive shaft 122 and the linkage shaft 131 are rotatably connected to the through-holes set inside the protection frame 136 through bearings, and the top wall of the protection frame 136 is fixedly connected to the top wall inside the notch 144.

[0036] There are two rotating shafts 141, and the two rotating shafts 141 are relatively distributed with reference to the vertical center axis of the stirring blade 133 as the symmetry axis, and the lower end of the rotating shaft 141 does not contact the stirring blade 1 123, ensuring that the rotation of the two groups of rotating shafts 141 is not affected. At the same time, during the rotation of the stirring blade 133, the two rotating shafts 141 movably connected to the stirring blade 133 are driven to synchronously perform circular motion.

[0037] The notch 144 is circular, which ensures that during the circular motion of the rotating shaft 141, the gear 146 fixedly sleeved on the outer ring of the rotating shaft 141 is meshed with the tooth block 145, thereby ensuring that the rotating shaft 141 can rotate on its own, thereby driving the rotation of the stirring blade 3 147 fixedly connected to the outer ring of the rotating shaft 141.

[0038] Working principle: When using a simulated die-casting test machine, first, the motor 121 is started to drive the drive shaft 122 connected to the output shaft of the motor 121 to rotate. At this time, the stirring blade 123 fixedly connected to the lower end of the drive shaft 122 rotates synchronously. The rotation of the stirring blade 123 stirs the molten metal in the melting box 9. At the same time, under the transmission action of the bevel gear set 134, the rotation of the drive shaft 122 drives the rotation of the linkage shaft 131 movably sleeved on the outer ring of the drive shaft 122, thereby ensuring the rotation of the stirring blade 133 fixedly connected to the outer wall of the lower end of the linkage shaft 131. The stirring blade 133 and the stirring blade 1 123 then rotate in different directions and stir the molten metal in the melting box 9 at the same time, making the molten metal processing efficiency higher;

[0039] At the same time, when the stirring blade 133 rotates in an annular manner, the rotating shaft 141 connected to the stirring blade 133 by the bearing inside the stirring blade 133 synchronously performs an annular motion, and the upper end of the rotating shaft 141 and the disc 142 move inside the annular groove 143 reserved on the top of the melting box 9, thereby ensuring the stability of the rotating shaft 141 during its own annular motion when the stirring blade 133 rotates. In addition, because the outer ring of the rotating shaft 141 is fixedly sleeved with a gear 146, the gear 146 and the inner plate of the top plate of the melting box 9 are arranged in a fixed manner when the rotating shaft 141 rotates in an annular manner. The tooth block 145 fixedly connected to the inner wall of the notch 144 realizes meshing connection, and the rotating shaft 141 realizes self-rotation at this time. The notch 144 is connected to the lower end of the annular groove 143 to ensure that the self-rotation and annular motion of the rotating shaft 141 are not affected, and the stirring blade 3 147 fixedly connected to the outer ring of the rotating shaft 141 rotates immediately, so that the stirring blade 3 147 stirs the molten metal inside the melting box 9 during the movement. The multi-directional stirring makes the melting efficiency of the molten metal inside the melting box 9 higher, and the die-casting operation can be realized after the molten metal is completely melted.

[0040] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
