Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a combination mold for the front bulkhead of a new energy vehicle. Background Technology

[0002] In automobile manufacturing, the front bulkhead is made by stamping sheet metal. The front bulkhead not only serves the function of a bulkhead, but also integrates structural components such as the air conditioning intake mounting plate and the steering gear mounting plate.

[0003] The automotive engine compartment front bulkhead assembly mold disclosed in Chinese Patent CN209998203U and the automotive front bulkhead assembly mold disclosed in Chinese Patent CN218744378U both feature front bulkhead punches that are easy to disassemble and assemble. When a front bulkhead punch is deformed or damaged, it can be replaced individually, thus avoiding resource waste and increased costs. However, while solving these problems, the aforementioned two front bulkhead assembly molds have the following drawbacks:

[0004] A set of molds has multiple front panel punches, and each front panel punch needs to have a fixed structure on both sides. Therefore, the overall structure is relatively complex. Moreover, during disassembly and assembly, the main mold plate needs to be removed from the stamping machine, and then the fixed structure of the damaged front panel punch needs to be removed separately, resulting in low disassembly and assembly efficiency. Utility Model Content

[0005] The purpose of this utility model is to at least solve one of the technical defects described in the background art.

[0006] Therefore, one objective of this utility model is to propose a front panel assembly mold for new energy vehicles, which aims to solve the problems of the complex overall structure and low assembly / disassembly efficiency of the existing front panel assembly mold.

[0007] To achieve the above objectives, one embodiment of this utility model provides a front bulkhead assembly mold for a new energy vehicle, comprising a mold main board, a base plate, and multiple front bulkhead punches. The mold main board is detachably mounted on the bottom of the base plate. The top of the mold main board has multiple insertion holes extending to its bottom, and the top of the mold main board has multiple limiting grooves corresponding to the insertion holes. The top of the front bulkhead punches is fixedly connected to an insertion block, and the top of the insertion block is fixedly connected to a limiting block. The front bulkhead punches are inserted from the top of the insertion holes, the insertion block is inserted into the interior of the insertion holes, and the limiting block is inserted into the interior of the limiting holes.

[0008] The beneficial effects are as follows: the front bulkhead punch is inserted into the mold main board, and the base plate is installed on the top of the mold main board, thereby fixing the front bulkhead punch. Therefore, multiple front bulkhead punches do not need to be fixed by one base plate, which simplifies the structure. When replacing the damaged front bulkhead punch, it is only necessary to remove the mold main board from the bottom of the base plate to replace the damaged front bulkhead punch, thus achieving high disassembly and assembly efficiency.

[0009] Furthermore, a connector is fixedly connected to the center of the top of the substrate, and multiple reinforcing ribs are welded and fixed to the outer surface of the connector, with the bottom of the reinforcing ribs welded to the top of the substrate.

[0010] In a preferred embodiment, the top edge of the mold main board is provided with multiple threaded holes, and the top edge of the substrate is provided with multiple through holes extending to its bottom. Bolts are inserted into the through holes, and the bolts are threaded into the threaded holes.

[0011] In a preferred embodiment, clamping plates are hinged to both sides of the top of the substrate, and a locking block is fixedly connected to the bottom of the clamping plate near the mold main board. A crossbeam is welded to the top of the clamping plate. A first groove is formed on the top of the substrate, and a spring is inserted into the first groove. The spring provides elastic support to the bottom of the crossbeam. Slots are formed on both sides of the mold main board, and the locking block is engaged in the slot.

[0012] Furthermore, positioning blocks are fixedly connected to both sides of the top of the substrate, and a connecting block is fixedly connected to the side of the top of the clamping plate near the substrate. Holes are opened on the sides of the connecting block and the positioning block, and a pin is used to pass through the holes on the connecting block and the positioning block.

[0013] Furthermore, a second groove is provided on the top of the substrate, an electric push rod is fixedly installed inside the second groove, and a traction rod is fixedly connected to the piston rod end of the electric push rod. A sliding groove is provided on the top of the crossbeam.

[0014] The beneficial effects are as follows: When assembling the mold main board and the base plate, it is only necessary to lower the base plate. After the locking block contacts the mold main board, the clamping plate unfolds outward. When the locking block at the bottom of the clamping plate corresponds to the locking groove on the side of the mold main board, the spring rebounds and the locking block will be locked into the locking groove, thereby completing the assembly of the mold main board and the base plate. When disassembling the mold main board, the electric push rod is retracted and the traction rod pulls down the crossbeam. The locking block will then disengage from the locking groove, and the base plate can be raised to complete the separation from the mold main board. Therefore, it is convenient to disassemble and assemble the mold main board, thereby facilitating the replacement of the damaged front bulkhead punch.

[0015] In a preferred embodiment, guide rods are fixedly connected to the four corners of the top of the mold main board, and guide holes corresponding to the guide rods are opened at the four corners of the bottom of the substrate.

[0016] Furthermore, both the top end of the guide rod and the bottom end of the guide hole are chamfered.

[0017] The beneficial effects are as follows: When assembling the main board and substrate of the mold, the guide rod is inserted into the guide hole, which can align multiple through holes and multiple threaded holes, or the locking block and the locking slot, thereby facilitating the assembly of the main board and substrate of the mold. The chamfer setting also facilitates the alignment of the guide rod and the guide hole.

[0018] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0029] This utility model provides a mold for assembling the front bulkhead of a new energy vehicle.

[0030] Example 1:

[0031] like Figure 1-2 As shown, it includes a mold main board 1, a base plate 2, and multiple front panel punches 3. The top of the mold main board 1 has multiple insertion holes 11 extending to its bottom, and the top of the mold main board 1 has multiple limiting grooves 12 corresponding to the insertion holes 11. The top of the front panel punches 3 is fixedly connected to an insertion block 31, and the top of the insertion block 31 is fixedly connected to a limiting block 32. The front panel punches 3 are inserted from the top of the insertion holes 11 and penetrate the mold main board 1. The insertion block 31 is inserted into the inside of the insertion holes 11, and the limiting block 32 is inserted into the inside of the limiting holes 12, thereby preventing the front panel punches 3 from falling downwards.

[0032] Multiple threaded holes 13 are provided at the top edge of the main mold plate 1, and multiple through holes 21 extending to the bottom of the base plate 2 are provided at the top edge of the base plate 2. The multiple through holes 21 correspond one-to-one with the multiple threaded holes 13. Bolts 22 pass through the through holes 21 and are threaded into the inside of the threaded holes 13, thereby fixing the main mold plate 1 to the bottom of the base plate 2. When stamping the front panel in one piece, the base plate 2 provides downward pressure to the main mold plate 1 and the limiting blocks 32 on the multiple front panel punches 3, thereby achieving the purpose of stamping the front panel.

[0033] A connector 23 for fixing to the end of the hydraulic cylinder of the stamping machine is welded and fixed at the center of the top of the substrate 2, and multiple reinforcing ribs 24 are welded and fixed on the outer surface of the connector 23. The bottom of the reinforcing ribs 24 is welded to the top of the substrate 2. During stamping, the reinforcing ribs 24 can reinforce the substrate 2 and prevent the substrate 2 from deforming under stress.

[0034] Guide rods 4 are fixedly connected to the four corners of the top of the mold main board 1. Guide holes 41 corresponding to the guide rods 4 are opened at the four corners of the bottom of the substrate 2. When the mold main board 1 is installed on the bottom of the substrate 2, the mold main board 1 and the substrate 2 can be aligned by aligning the guide rods 4 into the guide holes 41. Thus, the multiple through holes 21 and multiple threaded holes 13 correspond one-to-one, which facilitates the subsequent installation of bolts 22. Furthermore, the top end of the guide rods 4 and the bottom end of the guide holes 41 are both chamfered 42 to facilitate the alignment of the guide rods 4 and the guide holes 41.

[0035] The working principle of this embodiment is as follows: During assembly, multiple front panel punches 3 are respectively inserted into the corresponding insertion holes 11 on the main mold plate 1. Then, the main mold plate 1 is fixed to the bottom of the base plate 2 using bolts 22. The base plate 2 is connected to the hydraulic cylinder of the stamping machine through the top connector 23. During use, when individual front panel punches 3 are deformed or damaged, it is necessary to remove the bolts 22 and remove the main mold plate 1. The damaged front panel punch 3 can then be directly removed and replaced. After replacement, the main mold plate 1 is fixed to the bottom of the base plate 2 again using bolts 22.

[0036] Example 2:

[0037] like Figure 3 As shown, it includes a mold main board 1, a base plate 2, multiple front bulkhead punches 3, and a clamping plate 5, as follows: Figure 4 As shown, the top of the main mold plate 1 has multiple through holes 11 extending to its bottom, and the top of the main mold plate 1 has multiple limiting grooves 12 corresponding to the positions of the through holes 11. The top of the front panel punch 3 is fixedly connected to an insert block 31, and the top of the insert block 31 is fixedly connected to a limiting block 32. The specific structure of the front panel punch 3 can be found in [reference needed]. Figure 1 The front panel punch 3 is inserted from the top of the insertion hole 11 and passes through the main mold plate 1. The insertion block 31 is inserted into the inside of the insertion hole 11, and the limiting block 32 is inserted into the inside of the limiting hole 12, thereby preventing the front panel punch 3 from falling downward.

[0038] like Figure 5-6 As shown, positioning blocks 25 are welded and fixed on both sides of the top of the substrate 2, and a connecting block 51 is fixedly connected to the top of the clamping plate 5 near the substrate 2. Holes are opened on the sides of both the connecting block 51 and the positioning block 25. The clamping plate 5 is hinged to the top of the substrate 2 by using a pin to pass through the holes on the connecting block 51 and the positioning block 25.

[0039] like Figure 3-5As shown, a right-angled trapezoidal locking block 52 is fixedly connected to the bottom of the clamping plate 5 near the mold main board 1. A crossbeam 53 is welded and fixed to the top of the clamping plate 5. A first groove 26 is opened on the top of the base plate 2. A spring 6 is inserted into the first groove 26. The spring 6 provides elastic support for the bottom of the crossbeam 53. Slots 14 are opened on both sides of the mold main board 1. When the base plate 2 descends from directly above the mold main board 1, the inclined edge of the locking block 52 contacts the side of the mold main board 1, and the clamping plate 5 rotates, compressing the spring 6. When the locking block 52 corresponds to the slot 14, the spring 6 rebounds, pushing the clamping plate 5 to rotate, so that the right-angled edge of the locking block 52 is inserted into the slot 14, thereby completing the connection between the base plate 2 and the mold main board 1.

[0040] like Figure 5-6 As shown, a second groove 27 is provided on the top of the base plate 2, and a sliding groove 54 is provided on the top of the crossbeam 53. Before installing the clamping plate 5, the electric push rod 7 is inserted into the second groove 27, and the piston rod end of the electric push rod 7 is fixedly connected to the traction rod 71. When installing the clamping plate 5, the electric push rod 7 is rotated so that the traction rod 71 at the piston rod end can pass through the sliding groove 54. After the clamping plate 5 is installed, the electric push rod 7 is rotated so that the traction rod 71 and the sliding groove 54 are intersected. Finally, the electric push rod 7 is fixed to the base plate 2 using screws and other fasteners. When replacing the damaged front panel punch 3, by retracting the electric push rod 7, the traction rod 71 pulls down the crossbeam 53, which can disengage the locking block 52 from the locking groove 14, and the mold main plate 1 is removed from the bottom of the base plate 2. At this time, the damaged front panel punch 3 can be replaced.

[0041] like Figure 3 A connector 23 for fixing to the end of the hydraulic cylinder of the stamping machine is welded and fixed at the center of the top of the substrate 2 shown. A plurality of reinforcing ribs 24 are welded and fixed on the outer surface of the connector 23, and the bottom of the reinforcing ribs 24 is welded to the top of the substrate 2.

[0042] like Figure 4 As shown, guide rods 4 are fixedly connected to the four corners of the top of the main mold plate 1, and guide holes 41 corresponding to the guide rods 4 are opened at the four corners of the bottom of the base plate 2. The positions of the guide holes 41 can be found in [reference]. Figure 2 When the mold main board 1 is installed at the bottom of the substrate 2, the mold main board 1 and the substrate 2 can be aligned by aligning the guide rod 4 into the guide hole 41, thereby facilitating the alignment of the card block 52 and the card slot 14.

[0043] The working principle of this embodiment is as follows: When assembling the mold main board 1 and the base plate 2, the base plate 2 is first fixed on the hydraulic cylinder of the stamping machine through the connector 23. The mold main board 1 is placed below the base plate 2, and the four corners of the bottom of the mold main board 1 are aligned and supported by support rods to make it suspended. Then, multiple front panel punches 3 are inserted into the insertion holes 11 on the mold main board 1. Finally, by lowering the base plate 2, the locking blocks 52 on the clamping plate 5 are locked into the locking slots 14 on both sides of the mold main board 1.

[0044] When replacing the damaged front bulkhead punch 3, place support rods below the four corners of the main mold plate 1 to support the main mold plate 1. Then retract the electric push rod 7 and pull the crossbeam 53, so that the clamping plate 5 unfolds and the locking block 52 disengages from the locking slot 14. Then raise the base plate 2 to complete the separation from the main mold plate 1. Finally, replace the damaged front bulkhead punch 3.
