[0002] The connecting plates on the motorcycle include the upper connecting plate and the lower connecting plate. The lower connecting plate mainly provides load-bearing for the shock absorber and plays a steering role. The upper and lower connecting plates belong to the suspension components of the motorcycle and are one of the important components for connecting the steering devices. The mold used for the quenching heat treatment of the precision forging of the lower connecting plate is the mold used to make the lower connecting plate. Mold heat treatment refers to a metal heat processing process in which the material is heated, kept warm and cooled in the solid state to obtain the expected structure and performance.

[0003] When placing the mold in the existing mold heat treatment device, a special clamp is required to move the mold to a specified position inside the heat treatment device before placement can be achieved, or the clamp needs to be extended into the heat treatment device to complete the loading and unloading of the mold, which is relatively laborious and inconvenient to use. In addition, water vapor diffusion is easily generated during cooling and quenching, which increases the overall humidity in the factory and wastes coolant. Therefore, a lower connecting plate precision forging mold heat treatment device is proposed. Utility Model Content
