Description

Technical Field

[0001] The invention relates to the technical field of automobile parts manufacturing, in particular to an integrated molding die for an automobile swing arm. Background Art

[0002] The automobile swing arm, as a key component of the suspension, undertakes the important task of guiding and supporting the wheels. Its working condition directly affects the driving stability and handling of the car. If there is a problem with the automobile swing arm, the driver may feel the steering wheel shaking, and the vehicle is easy to deviate after the hand releases the steering wheel, and it is even difficult to control the direction when driving at high speed. In this case, if the problem is not serious, the direction can be stabilized by four-wheel alignment to avoid replacing the swing arm. The automobile swing arm plays the role of a connecting mechanism between the frame and the wheel. Unlike the hard link of a bicycle, it adopts a soft connection method and adds a shock absorbing mechanism. This design not only makes us more stable on rugged roads, but also improves the handling quality of the vehicle. It can reduce the bumpy feeling when driving on the surface, improve ride comfort, and also significantly improve the handling stability of the car. In daily driving, in order to protect the car's swing arm and suspension system, we should try to avoid driving on bumpy roads. If we can't avoid it, we should slow down to reduce the violent movement of the suspension and the contact between the swing arm and the road. If we suspect that the chassis is scratched or the swing arm is damaged, we can conduct a vehicle deviation test on a flat road, turn off the car's audio, listen carefully for any abnormal noise during driving, and observe whether the steering wheel shakes and whether the vehicle deviates when braking. These measures will help us discover and solve problems in a timely manner to ensure driving safety.

[0033] The bottom mold protection component 2 includes an assembly base 201, a lifting frame 202, a fixed cabin 203, a side seat 204, a protection cylinder 205, an external shock absorber 206, a lower fin 207 and a bottom mold cabin 208. The assembly base 201 is bolted to the upper inner side of the slotted base 103, the top side of the assembly base 201 is provided with a lifting frame 202, and the top side of the lifting frame 202 is provided with a fixed cabin 203, side seats 204 are provided at both ends of the fixed cabin 203, and a protection cylinder 205 is provided above the end of the side seat 204.

[0034] In the embodiment of the present invention, since the internal shock absorber 1013 and the external shock absorber 206 are installed, the shock absorption effect can be effectively achieved to avoid damage caused by excessive shaking of the equipment. The lower fins 207 on the side of the fixed cabin 203 can dissipate heat rapidly and uninterruptedly. When discharging is required, the protective cylinder 205 and the cylinder base 304 are used to work together to output power, so that the molding assembly 4 leaves the bottom mold protection component 2.

[0035] An external shock absorber 206 is arranged above the side of the fixed cabin 203 , a lower fin 207 is arranged on the outer side of the fixed cabin 203 , and a bottom mold cabin 208 is arranged on the top side of the external shock absorber 206 .

[0036] In the embodiment of the present invention, when it is necessary to place raw materials, the bottom mold cabin 208 is placed on the inner side of the fixed cabin 203 where the external shock absorber 206 is installed, and a sufficient amount of raw materials is placed in the bottom mold cabin 208.

[0037] The stamping component 3 includes a bolt base 301, a sliding rod 302, a top beam seat 303, a cylinder base 304, a hydraulic cylinder 305, a push rod 306 and an assembly cross frame 307. The bolt base 301 is bolted to the top of the slotted base 103 on all sides, the sliding rod 302 is arranged on the top side of the bolt base 301, and the top beam seat 303 is arranged on the top side of the sliding rod 302.

[0038] In the embodiment of the present invention, since both ends of the sliding rod 302 are provided with a bolt base 301 connected by bolts and a top beam seat 303 connected by bolts, it can be effectively facilitated to assemble and can effectively limit the running trajectory of the sliding cabin 401, thereby achieving the effect of fixing the motion trajectory.

[0039] The inner side of the top beam seat 303 is provided with a sleeve-mounted oil cylinder base 304 , and the top side of the oil cylinder base 304 is provided with a hydraulic cylinder 305 , the output end of the hydraulic cylinder 305 is provided with a push rod 306 , and the bottom end of the push rod 306 is provided with an assembly cross frame 307 .

[0040] In an embodiment of the present invention, when a stamping operation needs to be performed after the raw materials are placed, the hydraulic cylinder 305 on the top side of the cylinder base 304 is used to output power to drive the output end to operate. When the hydraulic cylinder 305 outputs power and operates telescopically, the push rod 306 moves downward. When the push rod 306 moves downward, the assembly cross frame 307 can drive the forming component 4 to descend.

[0041] The molding assembly 4 includes a sliding cabin 401, a threaded cabin 402, a threaded strip 403, a handle 404, a cabin outer frame 405, an upper fin 406, an upper shock absorber 407, a top plate 408, an outer mold cover 409, a drilled heat dissipation hole 4010 and a molding block 4011. The sliding cabin 401 is bolted to the lower ends of the assembly cross frame 307, and the threaded cabins 402 are arranged on the inner sides of the two ends of the sliding cabin 401, and the threaded cabins 402 are threadedly connected with the threaded strip 403, a handle 404 is arranged at one end of the threaded strip 403, and a cabin outer frame 405 is arranged on the outer side of one end of the threaded strip 403, and the side of the cabin outer frame 405 is provided with an upper fin 406, and the top side of the cabin outer frame 405 is provided with an upper shock absorber 407.

[0042] In an embodiment of the present invention, when effective replacement is required, the handle 404 is used to drive the threaded cabin 402 and the threaded strip 403 to spirally operate, so that the cabin outer frame 405 can be disassembled to facilitate replacement of the molding component 4, and the installed upper fins 406 can achieve further heat dissipation during molding and stamping, thereby avoiding damage to the product caused by overheating of the equipment.

[0043] A top plate 408 is provided below the outer frame 405 of the housing, and an outer mold cover 409 is provided on the inner side of the top plate 408 . Drilled heat dissipation holes 4010 are provided above the outer mold cover 409 . A molding block 4011 is provided below the inner side of the outer mold cover 409 .

[0044] In an embodiment of the present invention, when the molding assembly 4 descends, the sliding cabin 401 descends along a fixed trajectory under the limitation of the sliding rod 302. During the descending process, the outer mold cover 409 cooperates with the molding block 4011 and the bottom mold cabin 208 to achieve the molding effect. The drilled heat dissipation holes 4010 facilitate effective heat dissipation.

[0045] The working principle of the present invention is: when in use, the slotted base 103 is supported at the processing location through the cooperation of the pile foundation column 101 and the lower support frame 102, so as to achieve effective supporting operation. After support, it is convenient to effectively assemble the bottom mold protection component 2, the stamping component 3 and the forming component 4. When it is necessary to place the raw materials, the bottom mold cabin 208 is placed on the inner side of the fixed cabin 203 where the external shock absorber 206 is installed, and a sufficient amount of raw materials is placed in the bottom mold cabin 208. Since both ends of the sliding rod 302 are provided with a bolt base 301 connected by bolts and a bolted top beam seat 303, it can be effectively assembled and can effectively limit the sliding. The running track of the cabin 401 is realized to achieve the effect of fixed motion track. When the raw materials are placed and stamping operation is required, the hydraulic cylinder 305 on the top side of the cylinder base 304 is used to output power to drive the output end to operate. When the hydraulic cylinder 305 outputs power and operates telescopically, the push rod 306 moves downward. When the push rod 306 moves downward, the assembly cross frame 307 can drive the forming component 4 to descend. When the forming component 4 descends, the sliding cabin 401 descends on a fixed track under the limit of the sliding rod 302. During the descent, the outer mold cover 409 cooperates with the upper forming block 4011 and the bottom mold cabin 208 to achieve the forming effect. The drilled heat dissipation holes 4010 are provided for effective heat dissipation. The internal shock absorber 1013 and the external shock absorber 206 are installed to effectively achieve the shock absorption effect and avoid damage caused by excessive shaking of the equipment. The lower fins 207 on the side of the fixed cabin 203 can dissipate heat rapidly and continuously. When it is necessary to discharge the material, the protective cylinder 205 and the cylinder base 304 are used to jointly operate and output power, so that the molding component 4 leaves the bottom mold protection component 2. When effective replacement is required, the handle 404 is used to output and operate to drive the threaded cabin 402 and the threaded strip 403 to spirally operate, so that the cabin outer frame 405 can be disassembled, which is convenient for replacement of the molding. Component 4, and the installed upper fin 406 can achieve further heat dissipation effect during forming and stamping, avoiding damage to the product caused by overheating of the equipment. After the forming component 4 leaves the bottom mold protection component 2, the output end of the demoulding motor 105 is used to output power to drive the output end to operate, so that the output end of the demoulding motor 105 then enables the acceleration gear group 106 in the transmission chassis 104 to engage and transmit. After the acceleration gear group 106 engages and transmits, the screw group 107 engages and transmits. In this way, the lower hinge seat 109, the hinge rod 1010, and the upper hinge seat 1011 are transmitted and operated, and then the demoulding plate 1012 quickly demoulds the product.
