The limit post 5 controls the limit of the distance between the upper die head 1 and the lower die head 2. The third pressing post 33 and the fourth pressing post 34 realize the pressing riveting between the bracket 36 and the bottom cover 35 of the central control cooling assembly. After the riveting is completed, the upper die head 1 moves upward, and the bottom cover 35 of the central control cooling assembly with the pressing riveting completed is taken out, and the next operation can be carried out. In the present utility model, multiple support block grooves are provided. According to the position of the bracket 36 or the beryllium bronze elastic sheet installed on the bottom cover 35 of the central control cooling assembly, only the appropriate support block groove needs to be selected and the support block 7 is placed in the support block groove, and then the bottom cover 35 of the central control cooling assembly to be riveted can be subjected to pressing riveting without replacing the entire mold, which is applicable to the riveting installation of bottom covers 35 of different models of central control cooling assemblies, saving time and effort, greatly improving the processing efficiency of the bottom cover 35 of the central control cooling assembly, and having high practical value.
