Description

Technical Field

[0001] This utility model relates to the field of automotive parts casting technology, specifically to a casting fixture for an automotive swing arm control arm. Background Technology

[0002] The control arm is a key component of the vehicle chassis system, and its casting quality directly affects the vehicle's driving stability and safety.

[0003] Traditional automotive control arm casting fixtures typically require multiple tools for disassembling and assembling the upper and lower molds. The mold positioning and fitting precision are high, necessitating accurate alignment of locating pins and holes during disassembly and assembly. Inaccurate positioning can lead to improper mold installation or even damage. Operators may scratch the mold surface or damage the core due to improper force or tool use. Furthermore, multiple people are required to complete the process. The slow cooling rate of the casting within the mold extends the production cycle and causes uneven internal stress, making it prone to deformation, cracks, and other defects. Therefore, a new automotive control arm casting fixture is needed to address these issues.

The output end of the extension cylinder 207 is fixedly connected to the lower mold 202. The material supply and cooling assembly 3 includes a top frame 301, a top plate 302 is provided at the bottom of the top frame 301, a threaded pin 303 is provided inside the top plate 302, a washer 304 is provided at the bottom of the threaded pin 303, and an upper mold 305 is provided at the bottom of the threaded pin 303. A water storage tank 309 is installed on the top of the top frame 301. A water cooling channel 310 is fixedly connected to the bottom of the water storage tank 309. A cooling water pump 311 is installed on the side of the water cooling channel 310. The water cooling channel 310 extends into the interior of the upper mold 305. The lower mold 202 is fixed with screws 205 and the upper mold 305 is fixed with threaded nails 303, which can improve the ease of disassembly and assembly of the lower mold 202 and the upper mold 305. The easy disassembly and assembly of the mold can significantly reduce the time required for mold replacement.

[0033] The working process of this utility model is as follows: When the casting fixture for the automotive swing arm control arm designed in this scheme is in operation, the extension cylinder 207 is used to drive the lower mold 202 to rise and fall. At the same time, the extension rod 203 can ensure the stability of the rise and fall until the lower mold 202 and the upper mold 305 are tightly fitted. During casting, the opening of the electrically controlled valve 308 is used to transport the material from the hopper 306 to the conveying pipe 307, and finally into the combined cavity of the upper mold 305 and the lower mold 202. When removing the mold, the water cooling system composed of the water storage tank 309, the water cooling channel 310 and the cooling water pump 311 can be used to cool down the casting and the mold, so as to quickly remove the heat of the casting and the mold. The screw 303 can be unscrewed to separate the top plate 302 and the upper mold 305, so as to disassemble the upper mold 305. The screw 205 can be unscrewed to remove the lower mold 202 and the protective cover 206 from the base frame 101, thus completing the disassembly.
