Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1: like Figures 1 to 6 As shown, this utility model provides an electric vehicle motor housing molding device, including: a die-casting molding machine 1, a guide rod 101 and a hydraulic cylinder 102 are provided on the die-casting molding machine 1, a push plate 103 is arranged at the telescopic end of the hydraulic cylinder 102, the push plate 103 is slidably sleeved on the guide rod 101, and also includes a suction structure arranged on the push plate 103 for sucking up dust on the guide rod 101.

[0020] The suction structure includes a connecting cover 2 arranged below the push plate 103 and slidably sleeved on the guide rod 101, an annular tube 201 arranged on the inner wall of the connecting cover 2, a plurality of suction ports 202 evenly arranged on the annular tube 201, a connecting pipe 203 arranged on the annular tube 201 and connected to the annular tube 201, a fan 204 arranged on one side of the push plate 103, the suction end of the fan 204 arranged at one end of the connecting pipe 203, and a conveying pipe 205 arranged at the air outlet end of the fan 204. When the fan 204 is turned on, the suction ports 202 can suck the dust attached to the surface of the guide rod 101 into the annular tube 201, then into the fan 204 through the connecting pipe 203, and finally discharged through the conveying pipe 205.

[0021] Example 2: Based on Example 1, in order to clean the surface of the guide rod 101 and improve the dust removal effect, a cleaning structure is arranged on the suction structure.

[0022] The cleaning structure includes a rotating ring 3 rotatably installed inside the connecting cover 2, a gear ring 301 fixedly sleeved on the rotating ring 3, a gear 302 meshing with the gear ring 301, a motor 303 arranged on one side of the connecting cover 2, the output end of the motor 303 arranged on one side of the gear 302, several connecting boxes 304 evenly arranged on the rotating ring 3, and several cleaning cotton blocks 305 slidably installed in the corresponding connecting boxes 304. The motor 303 is turned on to drive the gear 302 to rotate. The gear 302 can drive the rotating ring 3 to rotate by meshing with the gear ring 301. The rotating ring 3 can drive the connecting boxes 304 to rotate in a circular motion, thereby driving the cleaning cotton blocks 305 inside the connecting boxes 304 to clean the surface of the guide rod 101.

[0023] The cleaning structure also includes an annular limiting groove 306 inside the rotating ring 3, and a limiting ring 307 arranged on the connecting cover 2 and rotatably installed in the annular limiting groove 306. The rotating ring 3 can rotate on the limiting ring 307 through the annular limiting groove 306. The setting of the annular limiting groove 306 and the limiting ring 307 can limit the position of the rotating ring 3 when rotating, and at the same time prevent the rotating ring 3 from getting loose from the connecting cover 2.

[0024] Example 3: Based on Example 1, in order to add lubricating oil to the cleaning structure for application onto the guide rod 101, a lubrication structure is arranged on the cleaning structure.

[0025] The lubrication structure includes a storage box 4 that is detachably installed inside the connecting box 304 and arranged on one side of the cleaning cotton block 305 for storing lubricating oil. A connecting hole 401 is opened on the inner wall of the storage box 4 and corresponds to the cleaning cotton block 305. When lubricating oil is poured into the storage box 4, the lubricating oil in the storage box 4 will come into contact with the cleaning cotton block 305 through the connecting hole 401 and be absorbed by it. Then, the motor 303 can be turned on to control the cleaning cotton block 305 to apply the absorbed lubricating oil to the guide rod 101.

[0026] The lubrication structure also includes an elastic component arranged on one side of the storage box 4 for pushing the storage box 4 to make the cleaning cotton block 305 stick to the guide rod 101.

[0027] Specifically, the elastic component includes a connecting plate 402 slidably installed inside the connecting box 304, a spring 403 arranged on one side of the connecting plate 402, one end of the spring 403 arranged on the inner wall of the connecting box 304, and a limiting rod 404 arranged on the inner wall of the connecting box 304. The connecting plate 402 is slidably sleeved on the limiting rod 404. Under the elastic force of the spring 403, the connecting plate 402 and the storage box 4 can be pushed to move towards the guide rod 101, thereby enabling the storage box 4 to drive the cleaning cotton block 305 to stick tightly to the guide rod 101.

[0028] Specifically, the elastic component also includes a T-shaped slot 405 inside the connecting plate 402, a T-shaped block 406 arranged on one side of the storage box 4 and detachably installed in the T-shaped slot 405, a sealing cover 407 detachably installed on the connecting box 304 and in contact with one side of the connecting plate 402, and a screw 408 passing through the sealing cover 407 and threaded inside the connecting box 304. By rotating and unscrewing the screw 408, the sealing cover 407 can be removed. At this time, the storage box 4 can be pulled to drive the T-shaped block 406 out of the T-shaped slot 405 so that the storage box 4 and the cleaning cotton block 305 can be removed for disassembly, cleaning or replacement.

[0029] Working principle: When the die-casting molding machine 1 is in use, the hydraulic cylinder 102 pushes the push plate 103 to move on the guide rod 101. During movement, the exhaust fan 204 can be turned on, so that the suction port 202 sucks the dust attached to the surface of the guide rod 101 into the annular pipe 201, and then enters the exhaust fan 204 through the connecting pipe 203, and is finally discharged through the conveying pipe 205. The conveying pipe 205 can be connected to the outside. At the same time, the motor 303 can be turned on to drive the gear 302 to rotate. The gear 302 can drive the rotating ring 3 to rotate through meshing with the gear ring 301. The continuously rotating rotating ring 3 can drive the connecting... The circular motion of the box 304 causes the cleaning cotton pad 305 inside the connecting box 304 to clean the surface of the guide rod 101. Under the elastic force of the spring 403, the connecting plate 402 and the storage box 4 can be pushed to move towards the guide rod 101. During the process, the connecting plate 402 can slide on the limiting rod 404. The setting of the limiting rod 404 can limit the movement direction of the connecting plate 402, prevent the connecting plate 402 from loosening, and prevent the spring 403 from bending when it extends and retracts. This allows the storage box 4 to drive the cleaning cotton pad 305 to stick tightly to the guide rod 101, improving the cleaning effect.

[0030] When lubrication of the guide rod 101 is required, the screw 408 can be unscrewed, the sealing cover 407 can be removed, and lubricating oil can be poured into the storage box 4. The lubricating oil in the storage box 4 will come into contact with the cleaning cotton block 305 through the connecting hole 401, allowing the cleaning cotton block 305 to absorb the lubricating oil. Then, the motor 303 can be turned on to control the movement of the cleaning cotton block 305 on the surface of the guide rod 101. The cleaning cotton block 305 can apply the absorbed lubricating oil to the guide rod 101 for lubrication. After opening the sealing cover 407, the connecting plate 402 and the storage box 4 can be exposed. Figure 6 In this state, the storage box 4 can be pulled to disengage the T-shaped card block 406 from the T-shaped card slot 405, so that the storage box 4 and the cleaning cotton block 305 can be removed, and the damaged or dirty cleaning cotton block 305 can be disassembled and replaced.

[0031] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
