[0023] Please refer to Figure 1 , Figure 2 , Figure 3 , The protection mechanism 8 includes a fixed seat 81. Fixed seats 81 are fixedly installed at both the left and right ends of the upper die 12 by bolts. A guide rod 82 is slidably adjusted inside the fixed seat 81. A second spring 83 is arranged outside the guide rod 82. One end of the second spring 83 is fixedly connected to a guide block 84, and the other end of the second spring 83 is fixedly connected to the fixed seat 81. By designing the second spring 83, the acting force of the second spring 83 can act on the guide block 84. A guide block 84 is fixedly connected to the bottom of the guide rod 82. The guide block 84 is slidably connected to the fixed seat 81. A connecting rod 85 is fixedly connected to the bottom of the guide block 84.

[0024] Please refer to Figure 1 , Figure 4 , Figure 5 , The connection mechanism 9 includes a fixed strip 91. The fixed strip 91 is slidably sleeved outside the fixed rod 7. A screw rod 92 is threadedly connected inside the fixed strip 91. The screw rod 92 is rotatably connected to the bottom plate 1 through a bearing.

[0025] The specific implementation process of the present utility model is as follows: During use, the output end of the hydraulic cylinder 11 drives the upper die 12 to move downward. The upper die 12 slides along the connecting rod 4, and the upper die 12 squeezes the first spring 5, so that the upper die 12 contacts the lower die 3 to complete mold closing, and the pressing work of automotive parts can be carried out. During the movement of the upper die 12, the upper die 12 drives the fixed seat 81 and the protective cover 86 to move downward. The protective cover 86 first moves downward to contact the fixed block 87 and stops moving, while the upper die 12 drives the fixed seat 81 to move and slide relative to the guide rod 82, the guide block 84 and the connecting rod 85 respectively, enabling the upper die 12 to continue moving downward to complete mold closing. The protective cover 86 is sleeved outside the connection between the upper die 12 and the lower die 3, which can shield and protect the outside of the mold, avoiding the situation that debris pops out due to the force on the workpiece during the pressing process, affecting safety.

[0026] When the mold needs to be disassembled, rotate the screw rod 92 to make the fixed strip 91 perform a threaded movement. The fixed strip 91 slides along the fixed rod 7. The fixed strip 91 drives the pressing rod 93 to move upward and separate from the inclined block 94. At this time, under the elastic action of the compressed third spring 99, it will push the slider 98 and the sliding rod 97 to move. The sliding rod 97 drives the sliding seat 96 and the inclined block 94 to move. At this time, the inclined block 94 drives the insertion block 95 to move and separate from the lower die 3. Subsequently, the lower die 3 and the upper die 12 can be removed. Then, moving the upper die 12 upward can remove the upper die 12 from the connecting rod 4, which is convenient for disassembling the mold, facilitating the replacement and use of the mold, and facilitating adaptation to the processing of different automotive parts.
