[0029] Reference Figure 1 as well as Figure 2 A servo welding machine includes a frame 1 and a lifting mechanism 2 arranged on the frame 1, an upper mold mechanism 3 arranged on the lifting mechanism 2, and a lower mold mechanism 4 arranged on the frame 1. When the servo welding machine is running, the lower mold mechanism 4 is used to install and fix the workpiece or plastic product, and the lifting mechanism 2 drives the upper mold mechanism 3 to move up and down so as to move away from or close to the lower mold mechanism 4 for welding processing.

[0030] Specifically, the frame 1 is used to install and support various mechanisms. The frame 1 includes a horizontal part and a vertical part. In this embodiment, the frame 1 is arranged in an integrated manner, that is, the horizontal part and the vertical part are connected as a whole. The integrated arrangement can ensure the structural strength of the frame 1 and the vertical part of the vertical part. At the same time, it can also avoid the assembly error caused by the installation of the split structure, thereby ensuring the straightness of the operation of the lifting mechanism 2, thereby effectively improving the processing accuracy of the servo welding machine.

[0031] In order to facilitate the installation of the lifting mechanism 2, the vertical portion of the frame 1 is provided with a guide rail 11 along its height direction, and the guide rail 11 is arranged vertically. The lifting mechanism 2 includes a lifting head 21 slidably connected to the guide rail 11 and a drive structure 22 for driving the lifting head 21, and the upper mold mechanism 3 is arranged on the lifting head 21. In this embodiment, the lifting mechanism 2 includes a servo motor 221 arranged on the frame 1 and a drive screw installed on the output shaft of the servo motor 221, and the lifting head 21 is arranged on the drive screw. The servo motor 221 drives the drive screw to rotate, and the rotating screw drives the lifting head 21 and the upper mold mechanism 3 to move back and forth along the guide rail 11. At the same time, a number of cooling fans 12 are provided on the top of the frame 1. The cooling fans 12 are connected to the interior of the frame 1. The cooling fans 12 can promptly remove heat from the frame 1 through the cooling fans 12, thereby ensuring the long-term stable operation of the servo welding machine.

[0032] The lower die mechanism 4 is located below the frame 1 and can be quickly installed and disassembled. Specifically, the lower die mechanism 4 includes a lower die mounting plate 41 provided on the frame 1, a lower die quick positioning chuck 42 provided on the lower die mounting plate 41, a lower die connecting block 43 provided on the lower die quick positioning chuck 42, and a lower die support 44 provided on the lower die connecting block 43. The lower die mounting plate 41 is fixedly provided on the frame 1 and arranged horizontally. The lower die mounting plate 41 can be fixed to the frame 1 by a threaded connection. In order to facilitate the installation of the lower die quick positioning chuck 42, the lower die mounting plate 41 has an adapter hole 411 for the installation of the lower die quick positioning chuck 42. The shape and size of the adapter hole 411 are adapted to the lower die quick positioning chuck 42. The lower die quick positioning chuck 42 includes a disk body 421, and the disk body 421 is embedded and installed in the adapter hole 411.

[0033] At the same time, the lower die mounting plate 41 is provided with a plurality of adapting grooves 412 along the circumference of the adapting holes 411. Accordingly, the disc body 421 is provided with disc adapting blocks 423 that match the adapting grooves 412. The disc adapting blocks 423 can be engaged or disengaged with the adapting grooves 412. By providing the disc adapting blocks 423 and the adapting grooves 412, when installing the lower die rapid positioning chuck 42, the disc body 421 can be installed and aligned by simply aligning the disc body 421 with the adapting holes 411 and inserting it, while simultaneously engaging the disc adapting blocks 423 with the adapting grooves 412.

[0034] Reference Figure 3 as well as Figure 4To facilitate installation of the lower mold connecting block 43, the disc body 421 has a sunken portion 4211 for engaging with the lower mold connecting block 43. The sunken portion 4211 is provided with a plurality of positioning protrusions 422, and the lower mold connecting block 43 has positioning grooves 431 that engage with the positioning protrusions 422. In this embodiment, the sunken portion 4211 has four positioning ends along the circumference of the disc body 421. The positioning protrusions 422 are rectangular blocks and are disposed one-to-one with each of the four positioning ends. The number and position of the positioning grooves 431 on the lower mold connecting block 43 correspond to the positioning protrusions 422.

[0035] At the same time, the sunken portion 4211 is provided with a disk positioning hole 4212, and the lower mold connecting block 43 is provided with a positioning post 432 for matching the disk positioning hole 4212. The positioning post 432 is slidably connected to the disk positioning hole 4212. To increase the smoothness and accuracy of assembly, the positioning post 432 is configured in a conical shape. Accordingly, the cross-section of the disk positioning hole 4212 is also configured in a conical shape to accommodate the positioning post 432. When installing the lower mold connecting block 43, it is only necessary to align the positioning post 432 of the lower mold connecting block 43 with the disk positioning hole 4212 and then adjust and rotate the lower mold connecting block 43 so that the positioning groove 431 of the lower mold connecting block 43 matches the positioning protrusion 422. This completes the installation and alignment of the lower mold quick positioning chuck 42.

[0036] The lower die support member 44 is used to mount and support the workpiece. A mounting groove for accommodating and mounting the workpiece is defined above the lower die support member 44. To facilitate the installation of the lower die support member 44, the lower die connection block 43 includes several connecting posts 433 that mate with the lower die support member 44. These connecting posts 433 are arranged circumferentially around the lower die connection block 43 and slideably connect to the bottom of the lower die support member 44 for alignment. The bottom of the lower die support member 44 is shaped to match the shape of the lower die connection block 43. Once the lower die support member 44 is installed into the lower die connection block 43, it engages with the lower die connection block 43. Furthermore, the lower die quick positioning chuck 42 is also provided with several disc support blocks 424. Once the lower die support member 44 is engaged and installed, the lower die support member 44 abuts against the disc support blocks 424, supporting the lower die support member 44 to ensure levelness. When the lower die support member 44 is installed in place, the upper die mechanism 3 will face the lower die support member 44 for processing.

[0037] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application.
