The directional structure includes several sets of springs, two sets of uprights, and guide sleeves adapted to the corresponding uprights. The load-bearing platform is slidably assembled within the positioning cavity, and its height is adjusted by the springs. When the springs are compressed, the platform surface is located within the positioning cavity. When the springs are in a restoring state, the platform surface and the upper surface of the pad are on the same plane. However, stamping dies are not easy to maintain and replace, and once the dies wear out, it affects the production quality of the products. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a diesel engine cover stamping machine that facilitates mold disassembly, maintenance and replacement, and ensures product processing quality.

[0004] This utility model discloses a diesel engine cover stamping machine, comprising a worktable, a base, a lower die, an upper die, a lower die fixing assembly, an ejector component, an upper die fixing assembly, and a stamping component. The base is installed at the bottom of the worktable. The lower die is mounted on the top of the worktable via the lower die fixing assembly. The ejector component is installed at the bottom of the worktable, and the lower die has an ejection hole at its bottom. The stamping component is installed above the worktable, and the upper die is mounted on the stamping component via the upper die fixing assembly. Starting the stamping component moves the upper die downwards via the upper die fixing assembly, cooperating with the lower die to complete the stamping process. The ejector component ejects the product from the lower die for easy unloading. The lower die can be removed from the top of the worktable via the lower die fixing assembly, and the upper die can be removed from the stamping component via the upper die fixing assembly, facilitating disassembly and maintenance of the lower and upper dies and ensuring product processing quality.

[0005] Preferably, the lower mold fixing assembly includes a mounting base, two electric telescopic rods, two fixing plates, two sets of limiting slide rods, and an upper plate. A mounting groove is provided on the top of the worktable, and the mounting base is inserted into the mounting groove. Fixing grooves are symmetrically provided at the left and right ends of the worktable with respect to the mounting groove. The electric telescopic rods are installed in the fixing grooves, and the fixing plates are located on the left and right sides of the fixing grooves. The telescopic ends of the electric telescopic rods pass through the fixing grooves and connect to the fixing plates. Limiting slide grooves are symmetrically provided at the front and rear ends of the worktable with respect to the electric telescopic rods. The limiting slide rods are symmetrically installed on the side walls of the fixing plates, and the limiting slide rods slide in the limiting slide grooves.

When the stamping plate moves downward, the upper die moves downward through the limit blocks and the mounting plate, enhancing stability. The locking screws are loosened and moved out of the screw holes, and the pull plate is pulled to move the limit blocks out of the limit slots, completing the disassembly of the upper die. This facilitates maintenance and replacement and ensures product processing quality.

[0008] Preferably, the ejection component includes multiple second electric telescopic rods and multiple push rods. The multiple second electric telescopic rods are installed at the bottom of the worktable. Multiple ejection holes are opened in the worktable, mounting base, and lower die. The telescopic ends of the second electric telescopic rods are equipped with push rods, which slide within the ejection holes. After stamping, the second electric telescopic rods are activated to push the push rods out, which can eject the product within the lower die for easy material discharge. When disassembling the mounting base, the second electric telescopic rods are activated to retract the push rods, which then move downward within the ejection holes.

[0009] Preferably, it also includes two sets of diagonal braces, a rear side plate, a guide slide rod, and a guide slider. The diagonal braces are installed between the bottom of the horizontal plate and the side wall of the vertical column. The rear side plate is installed on the rear side of the top of the worktable, and the top of the rear side plate is connected to the bottom of the horizontal plate.
