Detailed Implementation
[0031] The following is combined with Figure 1-7 This utility model will be described in detail.
[0032] A mold for producing convex bumps on a cover plate includes an upper mold and a lower mold. A guiding device and a positioning device are provided between the upper and lower molds. One side of the upper mold has a first convex bump punch 101 and a second convex bump punch 102 of different lengths. The lower mold, near the upper mold, has a first convex bump die 201 and a second convex bump die 202 respectively adapted to the first convex bump punch 101 and the second convex bump punch 102. One side of the upper mold also has a punching punch 103, and the lower mold, near the upper mold, has a punching die 203 adapted to the punching punch 103. The bottom of the punching die 203 has a blanking port 2031. This invention allows convex bumps of different heights on the same sheet material to be completed on the same mold. Furthermore, this mold can also perform punching operations, making it a multi-purpose mold that eliminates the need for multiple molds, reducing production costs and time.
[0033] Specifically, the upper die is the upper part of the mold. During the stamping process, the upper die moves downward and cooperates with the lower die to complete the forming operation. The convex punch and convex die are used to form the high convex 601 and low convex 602 parts of the cover plate 60. The punching punch 103 and the punching die 203 cooperate to complete the punching operation. The blanking port 2031 is used to discharge the waste material after punching.
[0034] In this embodiment, the upper mold includes an upper base 104 and a first template 105 fixed to the upper base 104 near the lower mold. The cross-sectional area of the first template 105 is smaller than that of the upper base 104 and it is located in the middle of the upper base 104. The lower mold includes a lower base 204 and a second template 205 fixed to the lower base 204 near the upper mold. The cross-sectional area of the second template 205 is smaller than that of the lower base 204 and it is located in the middle of the lower base 204.
[0035] In this embodiment, the guiding device includes a slidingly adapted guide post 106 and a guide sleeve 206. One of the guide post 106 and the guide sleeve 206 is located on the side of the upper base 104 or the first template 105 near the second template 205, and the other is located on the side of the second template 205 near the first template 105.
[0036] In this embodiment, the positioning device includes a plurality of positioning pins 107 and at least one positioning plate 207. Each positioning pin 107 is located on the side of the upper base 104 or the first template 105 near the second template 205. The positioning plate 207 is located on the side of the second template 205 near the first template 105. The positioning plate 207 has positioning holes 2071 adapted to the positioning pins 107, and the positioning plate 207 also has positioning pin avoidance holes 2072. Specifically, the positioning device is designed to improve the positioning accuracy between the upper and lower molds and avoid deviations during the molding process. The positioning pins are used for positioning the material on the lower mold, while the positioning pin avoidance holes 2072 are used to avoid the positioning pins and prevent interference.
[0037] In this embodiment, a ejector plate 108 located below the first template 105 is also included. A first elastic element (not shown in the figure) is provided between the first template 105 and the ejector plate 108. The ejector plate 108 is provided with a clearance hole for a clearance guide device, a positioning device, a first convex punch 101, a second convex punch 102 and a punching punch 103. Specifically, the ejector plate 108 is used to push the formed cover plate 60 downward from the upper die after stamping. In the natural, unpressurized state, the lower end face of the ejector plate 108 is closer to the lower die than the lower end faces of the first convex punch 101, the second convex punch 102, and the punching punch 103. In this way, during the stamping process, the ejector plate 108 first contacts the cover plate 60, and then the first elastic element is squeezed. The ejector plate 108 presses the cover plate 60 tightly onto the second template 205 of the lower die. As the upper die continues to move downward, the first convex punch 101, the second convex punch 102, and the punching punch 103 contact the material respectively and begin the forming operation. The number of the first elastic elements is 12-16.
[0038] In this embodiment, the second template 205 is provided with an upward ejection device 208 on the side near the first template 105. The upward ejection device 208 includes an ejector block and a second elastic element. Specifically, one end of the second elastic element is connected to the side of the second template 205 near the first template 105, and the other end of the second elastic element is connected to the ejector block. The upward ejection device 208 pushes the formed cover plate 60 upward from the lower mold, facilitating subsequent material removal operations.
[0039] In this embodiment, the first convex mold 201 and the second convex mold 202 are disposed on the second template 205, and the depth of the first convex mold 201 is greater than that of the second convex mold 202. Specifically, the length of the first convex mold 101 is greater than the length of the second convex mold 102. The first convex mold 101 and the first convex mold 201 cooperate to form a high convex 601, that is, a high convex portion on the cover plate 60. The second convex mold 102 and the second convex mold 202 cooperate to form a low convex 602, that is, a low convex portion on the cover plate 60. The depth of the first convex mold 201 and the second convex mold 202 depends on the required height of the two convex convex portions on the cover plate 60.
[0040] In this embodiment, the bottom of the first convex mold 201 is provided with a mounting hole 2091. A third elastic element 2092 and a rubber pad 2093 are installed in the mounting hole 2091. One end of the third elastic element 2092 is connected to the side of the lower base 204 near the second template 205, and the other end of the third elastic element 2092 is connected to the rubber pad 2093. Specifically, the rubber pad 2093 is an elastic rubber pad 2093, used for cushioning and shaping. The elastic rubber pad 2093 contacts the material during the molding process, providing uniform pressure to ensure the accurate shape of the convex portion. The third elastic element 2092 and the rubber pad 2093 improve the molding accuracy and stability of the convex portion.
[0041] In this embodiment, the second template 205 is provided with a recessed clearance 30. The recessed clearance 30 is provided to avoid interference that may occur during the stamping process, ensuring that there is no interference between the components during the stamping process.
[0042] In this embodiment, the upper base 104 and the lower base 204 are provided with a plurality of fixing holes 40 for fixing to the die-cutting equipment. A mold handle 50 is also provided on the outer side of the upper base 104 and the lower base 204. The mold is installed on the die-cutting equipment through the fixing holes 40, and the mold handle 50 facilitates the operator's handling and adjustment of the mold position. Specifically, the upper mold is fixed to the moving platen of the die-cutting equipment through the fixing holes 40. The moving platen is part of the die-cutting equipment and can move up and down under the drive of the equipment, thereby driving the upper mold to complete the stamping operation. The lower mold is fixed to the fixed platen of the die-cutting equipment through the fixing holes 40. The fixed platen is a fixed part of the die-cutting equipment, used to support the lower mold and maintain its stable position, ensuring accurate cooperation between the upper and lower molds during the stamping process.
[0043] The first elastic element, the second elastic element, and the third elastic element 2092 are springs, which play a restoring role; the material and sheet metal in this embodiment refer to the insulating protective cover plate 60 used in the energy storage battery of new energy vehicles. The production mold can also be used to produce and process other sheet metals; the punching punch 103 is provided with a sharp cutting edge. The material in the area to be punched is sheared and separated during the punching process. The length of the punching punch 103 needs to ensure that it can penetrate the area to be punched in the cover plate 60 and enter the punching die 203 to realize the punching operation; the convex punch does not have a cutting edge. It causes the material to undergo plastic deformation. Convex forming is an extrusion process. The convex punch extrudes the material into the required convex shape; the number of the first convex die 201, the second convex die 202, the punching die 203, the blanking port 2031, the positioning plate 207, and the spring-loaded ejection device 208 are all two.
[0044] The following is the process of using the cover plate convex bulge forming production mold proposed in this utility model:
[0045] (1) Before use, install the upper and lower molds in the designated positions of the die-cutting equipment (moving template and fixed template) through the fixing holes 40 to ensure that the molds are installed firmly, and check whether the positioning pins 107, positioning plates 207 and other parts of the molds are installed correctly to ensure that the upper and lower molds can be accurately aligned.
[0046] (2) Place the material to be stamped, such as cover plate 60, on the second template 205 of the lower die to ensure that the material is flat and in the correct position.
[0047] (3) Start the die-cutting equipment. The lower die remains stationary, while the upper die moves downward to cooperate with the lower die to complete the stamping operation. During the stamping process, the first convex punch 101 cooperates with the first convex die 201, and the second convex punch 102 cooperates with the second convex die 202. Each punch contacts the corresponding die and applies pressure, causing the designated area of the cover plate 60 to undergo plastic deformation in the die to form the required shape, thus completing the forming of the high convex part and the low convex part respectively. The third elastic element 2092 and the rubber pad 2093 below the first convex die 201 provide elasticity during the forming of the high convex 601, ensuring forming accuracy and stability. The punching punch 103 and the punching die 203 cooperate to punch out the required holes such as the mounting hole 2091 and the ventilation hole in the cover plate 60. The waste material after punching is discharged through the blanking port 2031.
[0048] (4) After stamping is completed, the ejector block moves upward under the reset action of the second elastic element, and applies an upward force to the formed cover plate 60. Meanwhile, the ejector plate 108 moves downward under the reset action of the first elastic element, and applies a downward force to the formed cover plate 60, so that the cover plate 60 is pushed out and separated from the upper and lower molds.
[0049] (5) The staff took out the molded cover plate 60, carried out subsequent inspection and processing, and cleaned the waste and residue in the mold to ensure the cleanliness of the mold and smooth use next time.
[0050] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
