Description

Technical Field

[0001] The present invention relates to the technical field of automobile wheel hub casting, and particularly relates to an efficient mold release agent applying tool for automobile wheel hub casting. Background Art

[0002] Automobile wheel hubs are important components of automobiles. They are annular metal structural parts connecting tires and axles. Their main functions include: supporting the weight of the vehicle, transmitting the torque of the vehicle's power system, maintaining the stability and controllability of the vehicle during driving, and at the same time realizing the heat dissipation and dynamic balance of the tires through reasonable design to ensure the safe and efficient operation of the vehicle. The materials of the wheel hubs are mostly aluminum alloy or steel. According to the manufacturing process, they can be divided into casting, forging, spinning and other types. Wheel hubs with different processes and materials have differences in strength, weight, cost and applicable scenarios.

[0003] In the prior art, during the casting process of automobile wheel hubs, the internal structure of the mold is complex with relatively narrow gaps, which are difficult to demold during demolding. It is necessary to apply a mold release agent on the inner wall of the mold to assist subsequent demolding. However, when applying the mold release agent, the efficiency is low, it is difficult to apply it quickly and efficiently, and more mold release agent is likely to accumulate at the narrow gaps, making it difficult to ensure that the mold release agent is evenly distributed inside the mold, which will affect the forming quality of the subsequent wheel hubs. Therefore, the present invention designs an efficient mold release agent applying tool for automobile wheel hub casting. Summary of the Invention
