Description

Technical Field

[0001] This utility model relates to the field of aluminum liquid stirring technology in die casting machines, and specifically to an aluminum liquid stirring device. Background Technology

[0002] A die-casting machine is a machine that uses pressure to cast metal. During operation, the die-casting machine injects molten metal into a mold under pressure, where it cools and solidifies. After the mold is opened, a solid metal casting is obtained. However, before the molten aluminum is injected into the mold, it needs to be stirred evenly using a stirring device to ensure the quality of the die-cast aluminum parts.

[0003] Traditional aluminum molten metal stirring equipment has a fixed stirring shaft position, making it impossible to flexibly adjust the stirring position. This is especially problematic in large-diameter aluminum molten metal holding furnaces, where the stirring shaft often fails to ensure uniform stirring of the molten metal. To address this, some aluminum molten metal stirring devices with adjustable stirring shaft positions have emerged on the market. For example, the Chinese utility model patent with authorization announcement number CN221231553U and patent name "An Aluminum Molten Metal Stirrer" uses guide blocks, a movable frame, a rack, a second motor, and gears to adjust the stirring position during the stirring process. When dealing with large quantities of molten aluminum, this allows for more comprehensive stirring of the molten metal inside the furnace, resulting in more uniform stirring and improved production quality of die-cast aluminum molten metal parts.

[0004] The above technical solution has the following technical problems: During the production process, sometimes in order to facilitate the operation of the aluminum liquid after stirring inside the holding furnace, it is necessary to move the stirring shaft laterally away from the top of the holding furnace to avoid interference or inconvenience to subsequent operations. Since the stirring equipment in the above solution can only move vertically, the operator needs to move the holding furnace, which undoubtedly increases the operator's labor intensity. In addition, traditional stainless steel stirring rods are prone to aluminum adhesion, corrosion, and short service life during the stirring process. Summary of the Invention

[0005] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide an aluminum liquid stirring device to solve the problem of limited movement space of the stirring shaft in existing aluminum liquid stirring equipment.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] This application provides an aluminum molten metal stirring device, which includes a column, a top connecting plate, an X-axis drive assembly, a Z-axis connecting seat, a Z-axis column, a Z-axis drive assembly, and a stirring assembly. The top connecting plate is horizontally fixedly installed at the top of the column. The Z-axis connecting seat is slidably installed on the top connecting plate, forming a sliding connection between the Z-axis connecting seat and the top connecting plate along the length of the top connecting plate. The X-axis drive assembly is connected to the Z-axis connecting seat and is used to drive the Z-axis connecting seat to move along the top connecting plate. The Z-axis column is vertically slidably installed on the Z-axis connecting seat. The Z-axis drive assembly is connected to the Z-axis column and is used to drive the Z-axis column to move up and down along the Z-axis. The stirring assembly is fixedly installed at the bottom of the Z-axis column.

[0008] Furthermore, the top connecting plate adopts an I-shaped channel steel structure, and the X-axis drive assembly is fixedly installed on one side of the top connecting plate.

[0009] Furthermore, X-linear guide rails are fixedly installed on the upper and lower opposite end faces of the top connecting plate, and a pair of X-slider blocks are provided on the back side of the Z-axis connecting seat, which are respectively slidably engaged with the pair of X-linear guide rails.

[0010] Furthermore, the Z-axis drive assembly includes a Z-axis drive motor and a gear. The Z-axis drive motor is fixedly mounted on the Z-axis connecting seat, and the output shaft of the Z-axis drive motor is fixedly connected to the gear. The Z-axis column is driven by meshing with the gear through a rack.

[0011] Furthermore, the Z-axis column is vertically installed in the inner cavity of the Z-axis connector, and vertically sliding Z-linear guide rails and Z-sliders are respectively provided on the opposite sides of the Z-axis column and the inner wall of the inner cavity of the Z-axis connector.

[0012] Furthermore, the stirring assembly includes a stirring motor, a mounting base, a stirring rod, and a heat insulation plate. The stirring motor is fixedly installed in the inner cavity of the mounting base, the mounting base is fixedly installed at the bottom end of the Z-axis column, the stirring rod is vertically rotatably installed on the mounting base, the stirring motor is connected to the stirring rod, and the heat insulation plate is fixedly disposed at the bottom end face of the mounting base.

[0013] Furthermore, the stirring rod is made of stainless steel that has undergone nitriding treatment.

[0014] Furthermore, guide rail limiting seats are fixedly installed at opposite ends of the X linear guide rail.

[0015] The beneficial effects of this utility model are as follows:

[0016] By setting the Z-axis connector to slide along the length of the top connecting plate, while the Z-axis column moves vertically up and down relative to the Z-axis connector, and the mixing assembly is directly fixed at the bottom of the Z-axis column, the mixing height of the mixing assembly can be adjusted by the up and down movement of the Z-axis column relative to the Z-axis connector; at the same time, the lateral position can be adjusted by the Z-axis connector relative to the top connecting plate, thus solving the problem of limited space for movement of the mixing assembly.

Detailed Implementation

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0024] See attached Figure 1 To be continued Figure 4 As shown, this embodiment provides an aluminum molten metal stirring device 100, which includes a column 1, a top connecting plate 2, an X-axis drive assembly 3, a Z-axis connecting seat 5, a Z-axis column 8, a Z-axis drive assembly 4, and a stirring assembly 6.

[0025] See attached document Figure 1 To be continued Figure 2As shown, one end of the top connecting plate 2 is fixedly installed on the top of the column 1, while the other end of the top connecting plate 2 extends horizontally outward. In some embodiments, to facilitate the installation of the X-axis drive assembly 3, the top connecting plate 2 adopts a channel steel structure with an I-shaped cross-section, so that the X-axis drive assembly 3 can be directly fixedly installed in the groove on one side of the top connecting plate 2, effectively utilizing the internal space of the top connecting plate 2.

[0026] See attached document Figure 1 As shown, in this embodiment, the X-axis drive assembly 3 is a drive cylinder. The drive cylinder is fixedly installed on the side of the top connecting plate 2. The piston rod of the drive cylinder is fixedly connected to the Z-axis connecting seat 5. That is, by the extension and retraction of the piston rod of the drive cylinder, the Z-axis connecting seat 5 is driven to move linearly back and forth relative to the top connecting plate 2.

[0027] Combined with reference to the appendix Figure 1 and attached Figure 2 As shown, X-linear guide rails 7 are fixedly installed on the top and bottom surfaces of the top connecting plate 2 along the length of the top connecting plate 2, respectively. Correspondingly, a pair of X-slider 10 arranged symmetrically on one side of the back of the Z-axis connecting seat 5 are installed. The pair of X-slider 10 slides with the pair of X-linear guide rails 7 on the top connecting plate 2 to enable the Z-axis connecting seat 5 to move laterally back and forth relative to the top connecting plate 2.

[0028] See attached document Figure 1 As shown, in order to prevent the X linear guide 7 from separating from the X slider 10, guide rail limit seats 9 are fixedly installed at opposite ends of the X linear guide 7. The presence of the guide rail limit seats 9 ensures that the X slider 10 will not separate from the X linear guide 7.

[0029] Combined with reference to the appendix Figure 2 and attached Figure 3 As shown, the Z-axis column 8 is installed in the inner cavity of the Z-axis connecting seat 5, and a vertical sliding connection is formed between the Z-axis column 8 and the Z-axis connecting seat 5. That is, Z-linear guide rails 12 are fixedly installed on the left and right sides of the Z-axis column 8, and the Z-linear guide rails 12 are arranged along the length of the Z-axis column 8. Correspondingly, a pair of Z-slider blocks 13 are fixedly installed on the inner sides of the left and right sides of the Z-axis connecting seat 5, and the pair of Z-slider blocks 13 are slidably installed on the pair of Z-linear guide rails 12. In this way, the Z-axis column 8 can move vertically up and down relative to the Z-axis connecting seat 5.

[0030] Continue to refer to the appendix Figure 2 and attached Figure 3 As shown, the Z-axis drive assembly 4 is fixedly installed on one side of the back of the Z-axis connector 5. The Z-axis drive assembly 4 is connected to the Z-axis column 8 and is used to drive the Z-axis column 8 to move up and down relative to the Z-axis connector 5.

[0031] See attached document Figure 3 As shown, in this embodiment, the Z-axis drive assembly 4 includes a Z-axis drive motor 41 and a gear 42. The Z-axis drive motor 41 is fixedly mounted on the Z-axis connecting seat 5, and the gear 42 is fixedly mounted on the output shaft of the drive motor. A rack 11 is fixedly mounted on one side of the back of the Z-axis column 8, and the gear 42 meshes with the rack 11. Thus, when the Z-axis drive motor 41 drives the gear 42 to rotate, the rotating gear 42 will drive the meshing rack 11 to move downward or upward. The rack 11 in the lifting and lowering state will then synchronously drive the Z-axis column 8 to move up and down.

[0032] See attached document Figure 1 and attached Figure 2 As shown, the stirring assembly 6 is fixedly installed at the bottom of the Z-axis column 8, so that the Z-axis column 8 can directly drive the stirring assembly 6 to move synchronously.

[0033] See attached document Figure 4 As shown, in this embodiment, the stirring assembly 6 includes a stirring motor 62, a mounting base 61, a stirring rod 63, and a heat insulation plate 64. The stirring motor 62 is fixedly installed in the inner cavity of the mounting base 61, and the mounting base 61 is fixedly installed at the bottom end of the Z-axis column 8. The stirring rod 63 is vertically rotatably mounted on the mounting base 61 through a provided bearing. The stirring motor 62 is connected to the stirring rod 63. Furthermore, to prevent damage to the stirring motor 62 inside the mounting base 61 from the high-temperature molten aluminum in the holding furnace during use, a heat insulation plate 64 is fixedly installed at the bottom end face of the mounting base 61. To improve the high-temperature resistance and corrosion resistance of the stirring rod 63 and effectively extend its service life, the stirring rod 63 is made of stainless steel, and the stainless steel has undergone a nitriding process.
