The cleaning component 35 is provided on the outside of the lower mold assembly 2.

[0023] By adopting the above technical solution, staff can use the lighting lamp 33 and other structures to provide auxiliary lighting when needed, thereby better coping with situations of insufficient light and ensuring the normal progress of work.

[0024] Specifically, the cleaning component 35 includes a suction bucket 351, a connecting pipe 352, a connecting box 353, a fan 355, a filter cloth 356, and an electric telescopic rod 357. The connecting box 353 is provided on the side of the base component 1 away from the transparent box 34. The connecting box 353 is connected to the bottom box 31 by the electric telescopic rod 357. The connecting pipe 352 is fixedly installed on the top of the connecting box 353. The suction bucket 351 is fixedly installed on both the upper and lower sides of the end of the connecting pipe 352 away from the connecting box 353. The filter cloth 356 is fixedly installed on the inner side of the connecting box 353. The fan 355 is fixedly installed on the side of the connecting box 353 away from the bottom box 31.

[0025] By adopting the above technical solution, staff can clean the inside of the lower mold assembly 2 and the bottom of the upper mold 5 when needed by using the cooperation of structures such as the fan 355 and the filter cloth 356, thereby reducing the difficulty of the cleaning work.

[0026] Specifically, the cleaning component 35 also includes a blockage block 354, which is threadedly installed on one side of the connecting box 353 and above the fan 355.

[0027] By adopting the above technical solution, staff can unscrew the blockage block 354 and remove dust and other objects blocked by the filter cloth 356 in the connection box 353 when needed, thereby better meeting the work needs in different situations.

[0028] In this embodiment, when a mold is needed for the forming of the wheelchair frame, the upper mold 5 is connected to the lifting device. The operator can then activate the various lights 33 inside the transparent box 34 of the lighting and cleaning device 3 for auxiliary lighting. Afterwards, the operator activates the electric telescopic rod 357 and the fan 355 in the cleaning assembly 35. The electric telescopic rod 357 drives the connecting box 353 and the suction hopper 351 to move back and forth. Under the action of the fan 355, dust and other debris from the inside of the lower mold assembly 2 and the bottom of the upper mold 5 are sucked into the two suction hoppers 351, then pass through the connecting pipe 352 into the connecting box 353, and are then blocked by the filter cloth 356. After the barrier is cleared, the suction bucket 351 and other structures are positioned so as not to interfere with the work. The electric telescopic rod 357 and the fan 355 are turned off. Then, the wheelchair frame material is fed into the lower mold assembly 2. The lifting device on the upper mold 5 is operated to lower the upper mold 5, thereby stamping and forming the material for use. The guide rod 4 serves as a guide. When needed, the operator can unscrew the blockage block 354 to remove the dust and other objects blocked by the filter cloth 356 in the connection box 353. The electric telescopic rod 357, the fan 355 and the lighting 33 are all electrically connected to the battery 32. The base assembly 1 serves as a support. Example 2

[0029] The difference between this embodiment and embodiment 1 is that the storage and transportation device 6 includes a storage box 61, casters 63 and a cover plate 64. The storage box 61 is provided on the side of the bottom box 31 away from the connecting box 353. The cover plate 64 is installed on the top of the storage box 61 by a hinge. Multiple casters 63 are fixedly installed on the bottom of the storage box 61.

[0030] By adopting the above technical solution, staff can store and transport the vehicle frame or tools when needed through the cooperation of the storage box 61 and the moving wheels 63, thereby better meeting the work needs in different situations.

[0031] Specifically, the storage and transport device 6 also includes a screw 62, which is threaded onto the bottom of the storage box 61.

[0032] By adopting the above technical solution, the staff can connect the storage box 61 and the bottom box 31 with the screw 62 when needed, thereby preventing the storage box 61 from moving and better meeting the needs of the work.

[0033] In this embodiment, when needed, the staff can open the cover 64 in the storage and transportation device 6 and put the vehicle frame or tools into the storage box 61 for storage. Then, the staff can turn the screw 62 to detach it from the bottom box 31, so that the storage box 61 and the bottom box 31 are no longer relatively fixed. Then, the staff can push the storage box 61 and move it through the various moving wheels 63 to transport the items in the storage box 61.

[0034] The structure and principle of the base assembly 1 (comprising a base and a buffer assembly), the lower die assembly 2 (comprising a lower die, a template, and a replacement assembly), the guide rod 4, and the upper die 5 in this utility model have been disclosed in a vehicle frame stamping die disclosed in Chinese Patent Application No. 202220753616.6. Its working principle involves setting a replacement assembly to activate the telescopic shafts of two micro-cylinders inside the telescopic end of the telescopic component to retract. When the telescopic end of the micro-cylinders is fully retracted, it can disengage from the interior of the second mounting groove. Then, by fully retracting the telescopic shaft of the telescopic component, it can disengage from the first mounting groove on the bottom surface of the template and the through groove of the concave plate, thus completing the template disassembly. When replacing with another template, after placing the template inside the concave plate, the telescopic component and the micro-cylinders are activated, causing... The telescopic shafts of both the telescopic component and the miniature cylinder are located inside the first and second mounting slots, respectively, allowing for easy installation. This facilitates template replacement without requiring a complete replacement of the lower and upper molds, simplifying the replacement process and improving usability. By incorporating a buffer assembly, the pad and silicone plate are fixedly connected from bottom to top between the base and the lower mold via slots on the base surface. The pad is made of pressure-resistant and elastic metal, while the silicone plate is made of silicone, providing elasticity between the base and the lower mold, along with good pressure resistance. Combined with the elasticity of the pull plate, this facilitates the rapid return of the lower mold to its original position when the upper mold moves upward. In summary, this accelerates the quick opening of the lower and upper molds, reduces burrs at the workpiece edges, and improves workpiece quality.

[0035] The working principle and usage process of this utility model are as follows: When a mold is needed for the molding of the wheelchair frame, the upper mold 5 is connected to the lifting device. The operator can activate the various lights 33 in the transparent box 34 of the lighting and cleaning device 3 for auxiliary lighting. Then, the operator activates the electric telescopic rod 357 and the fan 355 in the cleaning assembly 35. The electric telescopic rod 357 drives the connecting box 353 and the suction hopper 351 to move back and forth. Under the action of the fan 355, dust and other objects inside the lower mold assembly 2 and at the bottom of the upper mold 5 are sucked into the two suction hoppers 351, then pass through the connecting pipe 352 into the connecting box 353, and are blocked by the filter cloth 356. After cleaning, the suction hopper 351 and other structures are placed in a position that does not affect the work, the electric telescopic rod 357 and the fan 355 are turned off, and then the wheelchair frame material is sent into the lower mold assembly. In component 2, the lifting device on the upper mold 5 is operated to drive the upper mold 5 to descend, thereby stamping and forming the raw material for use. The guide rod 4 plays a guiding role. When needed, the operator can unscrew the blockage block 354 to remove dust and other objects blocked by the filter cloth 356 in the connecting box 353. The electric telescopic rod 357, the fan 355 and the lighting lamp 33 are all electrically connected to the battery 32. The base assembly 1 plays a supporting role. When needed, the operator can open the cover plate 64 in the storage and transportation device 6 and put the frame or tools into the storage box 61 for storage. Then, the operator can turn the screw 62 to detach it from the bottom box 31, thereby making the storage box 61 lose its relative fixation with the bottom box 31. Then, the operator can push the storage box 61 and move it through the various moving wheels 63 to transport the items in the storage box 61.
