[0027] A first guide rail 45 is provided on the top surface of the conveyor plate 41 along its length direction, and a first groove 46 is provided on the bottom surface of the moving block 44 opposite to the first guide rail 45. The first groove 46 is slidably connected to the first guide rail 45.

[0028] The moving block 44 and the dual-station alternation mechanism 5 have a first insertion slot 47 on their opposite side wall for inserting the connecting rod 7. The connecting rod 7 is inserted into both the moving block 44 and the dual-station alternation mechanism 5 at the same time to achieve the connection between the two.

[0029] The dual-station alternation mechanism 5 includes a dual-station support 51, a rotation drive assembly disposed below the dual-station support 51, and a push assembly disposed on one side of the rotation drive assembly. The dual-station support 51 consists of two parallel support seats 501, and the right support seat 501 is disposed opposite to the mold drive mechanism 4.

[0030] The rotation drive assembly includes a rotating shaft 52, a worm gear 53, a worm 54, a mounting plate 55, a motor 56, and a base plate 57. The upper end of the rotating shaft 52 is fixedly connected to the bottom surface of the dual-station support 51, and the lower end is rotatably connected to the base plate 57.

Then, the rotation drive assembly is activated to reposition the two sets of mold assemblies 6, changing the mold assembly 6 to be used to the position opposite to the drive mechanism 4. The push assembly is then activated again to reset it, so that the mold assembly 6 to be used abuts against the drive mechanism 4 and is connected by the connecting rod 7. Then, the drive mechanism 4 is activated to move the mold assembly 6 to be used to the processing station, thus easily completing the mold change.

[0034] A second guide rail 513 is provided on the top surface of the mounting base 512. The second guide rail 513 is fixedly connected to the mounting base 512.

A third sliding groove 611 is provided on the bottom surface of the mold base 61, and the third sliding groove 611 is slidably connected to the first guide rail 45 on the conveyor plate 41. A second insertion groove 612 for inserting the connecting rod 7 is provided on the side of the mold base 61 opposite to the mold drive mechanism 4. During operation, the connecting rod 7 is simultaneously inserted into the first insertion groove 46 and the second insertion groove 612 to realize the connection between the mold drive mechanism 4 and the mold assembly 6.

[0036] The base frame 1 includes a first mounting base 11, a second mounting base 12, and four support columns 13 connecting the first mounting base 11 and the second mounting base 12. The four support columns 13 are distributed at the four corners of the first mounting base 11.

[0037] The extrusion cylinder mechanism 2 is used to place the billet and includes an extrusion cylinder body 21 and a first hydraulic cylinder 22. The extrusion cylinder body 21 is slidably connected to the support column 13, and the first hydraulic cylinder 22 is mounted on the second mounting base 12. The output end of the first hydraulic cylinder 22 is fixedly connected to the extrusion cylinder body 21.

[0038] The extrusion rod mechanism 3 includes an extrusion rod body 31, a connecting plate 32, and a second hydraulic cylinder 33.

The second hydraulic cylinder 33 is mounted on the second mounting base 12, and the output end of the second hydraulic cylinder 33 is fixedly connected to the connecting plate 32.

[0039] The working principle of this utility model is as follows: When it is necessary to change the mold during processing, the mold assembly 6 to be used is first placed on the left support seat 501 of the dual-station support 51. The used mold assembly 6 is transported to the right support seat 501 through the mold drive mechanism 4. Then, the connecting rod 7 between the mold drive mechanism 4 and the used mold assembly 6 is released. Next, the pushing component is activated, and the cylinder 511 pushes the base plate 57, which drives the rotation drive component, the dual-station support 51 and the two sets of mold assemblies 6 on it to move away from the mold drive mechanism 4 along the second guide rail 513, making room for the rotation and repositioning of the dual-station support 51. After that, the rotation drive component is activated, and the motor 56 drives the worm gear 54 to rotate. The worm gear 54 drives the worm wheel 53 to rotate, and the worm wheel 53 drives the dual-station support 51 to rotate, realizing the repositioning of the old and new mold assemblies 6, so that the mold assembly 6 to be used is rotated to the position opposite to the mold drive mechanism 4. The push assembly is then activated, and cylinder 511 pulls the base plate 57 to reset, allowing the mold assembly 6 to be used to abut against the mold drive mechanism 4. Connecting rod 7 is simultaneously inserted into the first insertion slot 47 of the moving block 44 and the second insertion slot 612 of the mold base 61, completing the connection between the mold drive mechanism 4 and the mold assembly 6. Then, the mold drive mechanism 4 is activated, and hydraulic cylinder 43 pulls the moving block 44, moving the mold assembly 6 along the first guide rail 45 to the processing station. At this time, the first hydraulic cylinder 22 of the extrusion cylinder mechanism 2 pushes the extrusion cylinder body 21 to move, sending the billet to the appropriate position. The second hydraulic cylinder 33 of the extrusion rod mechanism 3 pushes the connecting plate 32, causing the extrusion rod body 31 to move towards the extrusion cylinder body 21, applying pressure to the billet. Under pressure, the billet passes through the channel formed by the mold core 63 and the mold sleeve 62 of the mold assembly 6, and is extruded into the desired shape, completing the metal processing.

[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
