It is used to cooperate with the upper riveting mold 2 and perform riveting processing. The second fixing part 602 is located at the lower part of the lower riveting mold 6 and is integrally formed with the lower riveting mold 6. The second fixing hole 501 is a blind hole and is provided on the top surface of the lower template 5 and located at the center of the lower template 5. When the second fixing part 602 is inserted into the second fixing hole 501 and the two are interference-fitted, the lower riveting mold 6 is fixed on the lower template 5. This can be understood by those skilled in the art.

[0034] Furthermore, the upper mold assembly also includes a pressing component 12. Specifically, in this embodiment, the pressing component 12 is columnar and made of polyurethane material. It has a pressing mounting hole 1201, which is a through hole and extends along the height direction of the pressing component 12. The diameter of the pressing mounting hole 1201 is equivalent to the diameter of the upper riveting mold 2. When the pressing mounting hole 1201 is fitted onto the upper riveting mold 2 from bottom to top and the two are interference-fitted, the pressing component 12 is fixed to the upper riveting mold 2. When the upper mold assembly and the lower mold assembly cooperate with each other, the top surface of the pressing component 12 abuts against the bottom surface of the upper template 1, and its bottom surface presses the slide rail body 10 onto the lower mold assembly, thereby pressing and fixing the slide rail body 10. This is understood by those skilled in the art.

[0035] Furthermore, the lower mold assembly also includes a positioning component 13. Specifically, in this embodiment, the positioning component 13 is annular and fixedly mounted on the top surface of the lower template 5 and surrounds the periphery of the lower riveting mold 6.

When the positioning mounting part 1301 is inserted into the second mounting groove 502 from top to bottom and the two are interference-fitted, the positioning component 13 is fixedly mounted on the lower template 5. The central axis of the positioning component 13 coincides with the central axis of the lower riveting mold 6. The diameter of the inner cavity of the positioning component 13 is equivalent to the diameter of the support wheel 9, so that the support wheel 9 can be positioned on the lower template 5. This is understood by those skilled in the art.

[0036] Furthermore, the lower mold assembly also includes a support member 14. Specifically, in this embodiment, the support member 14 is fixed to the lower mold pad 7 by a fastening member, and the support member 14 extends towards the front of the lower mold assembly. When the slide rail body 10 is placed on the lower mold assembly, the support member 14 supports the bottom of the slide rail body 10, making the slide rail body 10 more stably placed on the lower mold assembly, thus ensuring the riveting effect of the slide rail. This is understandable to those skilled in the art.

[0037] See Figure 9-10 When riveting the slide rail support wheel, the riveting mold first places the support wheel 9 on the lower mold assembly and embeds it in the positioning component 13. The bottom end of the shaft of the support wheel 9 abuts against the lower riveting mold 6. Then, the slide rail body 10 is placed on the lower mold assembly, above the support wheel 9 and supported by the support component 14. The shaft of the support wheel 9 passes through the slide rail body 10. Next, the shim 11 is placed on the lower mold assembly, above the slide rail body 10. The shaft of the support wheel 9 passes through the shim 11. Then, the stamping equipment is started, the upper mold assembly moves downward, and the pressing component 12 presses the slide rail body 10 onto the lower mold assembly. Then, the upper mold assembly continues to move downward, and the upper riveting mold 2 and the lower riveting mold 6 cooperate to stamp and deform the shaft of the support wheel 9, so that the support wheel 9 and the shim 11 are clamped onto the slide rail body 10. After the riveting is completed, the upper mold assembly is reset upward, and finally the slide rail is taken out.
