The bottom of the upper mold 3 is fixedly provided with two rows of positioning blocks 31 corresponding to the two rows of positioning grooves 21. When the upper mold 3 descends, the two rows of positioning blocks 31 cooperate with the two rows of positioning grooves 21 to make the upper mold 3 slide, thereby completing the positioning of the mold.

[0035] During equipment installation, the staff installs the lower mold 2 and the upper mold 3. Then, the upper mold 3 is slid at the bottom of the support plate 4 until it is almost aligned with the top of the lower mold 2. The upper mold 3 is then lowered, and the two rows of positioning blocks 31 cooperate with the two rows of positioning grooves 21 to make the upper mold 3 slide, thus completing the positioning of the upper mold 3 and the lower mold 2. The lower mold 2 and the upper mold 3 can then cooperate to perform stamping processing on the sheet metal.

[0036] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The lower mold 2 has a forming groove 22 on its top. The upper mold 3 has a forming block 32 fixedly installed at its bottom corresponding to the forming groove 22. The support frame 1 has a bellows 7 fixedly installed on its inner side. The support plate 4 has a sliding groove A41 on its top. Two slide rails 411 are symmetrically arranged on the inner side of the sliding groove A41. The two slide rails 411 slide together to provide a slider 42. The upper mold 3 is fixedly installed at the bottom of the slider 42 by a fixing plate 5 and a hydraulic cylinder 6. The fixing plate 5 is fixedly installed at the bottom of the slider 42. The bottom of the fixing plate 5 is fixedly installed at the fixed end of the hydraulic cylinder 6. The fixed end of the hydraulic cylinder 6 is fixedly installed with a mounting plate 61. The bottom of the mounting plate 61 is fixedly installed at the top of the upper mold 3.

[0037] When the device is installed, the installation plate 61 is driven to descend by the hydraulic cylinder 6, so as to drive the upper die 3 to descend, make the two rows of positioning blocks 31 cooperate with the two rows of positioning grooves 21, move the upper die 3, make the forming grooves 22 completely align with the forming blocks 32, and simultaneously make the installation plate 61, the hydraulic cylinder 6 and the fixing plate 5 connected with the hydraulic cylinder 6 move, make the fixing plate 5 drive the sliding blocks 42 slide in the inner sides of the two slide rails 411, complete the positioning of the upper die 3, and then the installation plate 61 is driven to ascend by the hydraulic cylinder 6, so as to reset the upper die 3;

[0038] After the device is positioned, the installation plate 61 is driven to ascend and descend by the hydraulic cylinder 6, so as to make the upper die 3 ascend and descend, cooperate with the lower die 2 to stamp the plate, blow air cooling to the processed front top cover through the air bellow 7 after stamping, and complete the stamping production of the front top cover.

[0040] In order to avoid that the upper die 3 moves during stamping, after the upper die 3 is positioned, the four gear boxes 513 are driven to work by the two driving motors 514, the four gear boxes 513 drive the four threaded rods 512 to rotate, so as to drive the four threaded moving shells 511 to move, abut against the bottom of the support plate 4, fix the fixing plate 5 and the support plate 4, and thus the upper die 3 cannot move in the horizontal direction;

[0041] The four limiting rods 5111 are slidably arranged in the four limiting grooves 52, limit the four threaded moving shells 511, and prevent the threaded rods 512 from rotating.
