[0020] The embodiments of this utility model relate to an integrated punching die for shaping and side punching of new energy electronic control housings, such as... Figure 1-5 As shown, the die includes an upper die base 1 and a lower die base 2. The lower end of the upper die base 1 is equipped with a vertically movable pressure plate 4. The upper die base 1 and the pressure plate 4 are limited by a limiting bolt 5. An elastic element 6 is also installed between the upper die base 1 and the pressure plate 4. The lower end of the upper die base 1, located on the right side of the pressure plate 4, is equipped with a side punch slider 12 and a power cylinder 11 that drives the side punch slider 12 to slide laterally. The left end of the side punch slider 12 is equipped with multiple water hole punching tools 13. Several upper straightening blocks 7 are installed on the lower edge of the pressure plate 4. Edge cutting tools 14 are arranged around the lower end of the upper die base 1, located around the pressure plate 4. The upper end of the lower die base 2 is equipped with a base plate 3. A shaping block 18 is provided on the upper end of the base plate 3. Several lower straightening blocks 17 are installed on the edge of the shaping block 18.

[0021] Reference Figure 1 As shown, the upper mold base 1 and the pressure plate 4 are limited by multiple limiting bolts 5. The upper mold base 1 has through holes for the rods of the limiting bolts 5 to pass through. The caps of the limiting bolts 5 are too large to pass through the through holes. The rods of the limiting bolts 5 pass through the through holes and are connected and fixed to the pressure plate 4.

[0022] A plurality of elastic elements 6 are provided between the upper mold base 1 and the pressure plate 4. The elastic elements 6 are generally arranged in two rows, with at least two elastic elements 6 in each row. The elastic elements 6 are preferably gas springs, which are existing components and can be purchased directly from the market. Ordinary springs can also be used as elastic elements 6.

[0023] The lower mold base 2 is equipped with a sliding push rod 8 at each of the four corners of the base plate 3. The bottom of the lower mold base 2 is equipped with an ejector cylinder 9 that drives the push rod 8. After the product processing is completed, the four ejector cylinders 9 control their respective push rods 8 to push the product up at the four corners of the bottom of the product, making it easy to remove the product.

[0024] The lower mold base 2 is equipped with a foot 10 on each side of its lower end. The foot 10 is used to lift the lower mold base 2 to avoid interfering with the installation and arrangement of components such as the ejector cylinder 9.

[0025] A pressing cylinder 15 is vertically installed at the center of the front end of the upper mold base 1, and a material handle pressing head 16 is installed at the lower end of the piston rod of the pressing cylinder 15.

[0026] Both the upper orthopedic block 7 and the lower orthopedic block 17 are made of brass. The use of brass as the material for the orthopedic blocks is to prevent damage to the product during side orthopedic mold opening and closing.

[0027] The left end of the side punching slider 12 is equipped with a tool fixing plate 19. The tool fixing plate 19 and the side punching slider 12 are connected and fixed by fasteners. The water hole punching tool 13 is fixed on the side punching slider 12 through the tool fixing plate 19. The shape of the water hole punching tool 13 is cylindrical or cuboid.

[0028] The side-impact slider 12 has a T-shaped slot 20 in the middle of its right side, and the piston rod of the power cylinder 11 has a snap-fit ​​part at its end that matches the T-shaped slot 20; the snap-fit ​​part cooperates with the T-shaped slot 20 to achieve quick connection between the piston rod of the power cylinder 11 and the side-impact slider 12.

[0029] First, the upper mold base 1 and the lower mold base 2 are fixed on the hydraulic press. The lower mold base 2 is fixed and does not move, while the upper mold base 1 moves up and down with the hydraulic press. Next, the die-cast electrical control housing 21 is placed on the base plate 3. The shaping block 18 at the upper end of the base plate 3 is inserted into the lower cavity 25 of the electrical control housing 21. The shape of the shaping block 18 matches the inner wall of the lower cavity 25 to limit the electrical control housing 21. The hydraulic press controls the upper mold base 1 to move downward. The pressure plate 4 at the lower end of the upper mold base 1 is inserted into the upper cavity 25. The pressure plate 4 presses against the bottom surface of the upper cavity 25. Multiple upper straightening blocks 7 and multiple lower straightening blocks 17 correct the concave deformation of the inner wall of the cavity 25. The upper mold base 1 continues to move downward. The edge-cutting blades 14 around the moving pressure plate 4 cut off the excess flow channel material 23 adhering to it. Then, the pressing cylinder 15 controls the material handle pressure head 16 to press down the material handle 22, so that the cut flow channel material 23 can be separated from the electrical control housing 21. Then, the power cylinder 11 is started, which controls the side punching slider 12 and multiple water hole punching blades 13 to move to the left. The multiple water hole punching blades 13 punch the multiple water hole 24 positions. After completing all the above processes, the hydraulic press controls the upper mold base 1 to reset upward. The four ejection cylinders 9 control their respective ejector rods 8 to press against the four corners of the bottom of the electrical control housing 21 to lift the electrical control housing 21, making it easy to remove the electrical control housing 21.

[0030] This invention can not only remove excess flow channel material 23 around the electrical control housing 21, but also complete the side punching of water holes and the shaping of the recessed area on the inner wall of the chamber 25, thereby realizing multiple processing steps, greatly improving processing efficiency and reducing production costs.
