Problems solved by technology
When the center plate of the rim bottom mold is cooled, it is usually used to drill holes in the center plate, and at the same time weld the air duct on the center plate to align with the hole of the center plate. This method is air-cooled and requires a large amount of air, but the cooling effect But it is not ideal, resulting in a long production cycle, slow solidification rate of aluminum water, coarse grains, low tensile strength of the mounting surface, poor performance, and needs to be remade for cooling, which is a serious waste of cost

Abstract
The invention relates to an intermediate plate cooling structure, comprising a ring-shaped intermediate plate, and an air inlet main pipe fixed on the intermediate plate; a plurality of air outlet holes are arranged on the ring surface of the intermediate plate; an air inlet branched pipe is arranged in the air inlet main pipe; a water inlet pipe is arranged at the outer side of the air inlet main pipe and is communicated with the air inlet branched pipe. According to the intermediate plate cooling structure, the air outlet holes are arranged on the intermediate plate, air and water are synchronously fed via the air inlet branched pipe and the water inlet pipe, the intermediate plate is cooled by using the air-with-water atomizing mode, the solidification rate of molten aluminum is high, the particle is fine, the tensile strength of a mounting surface is high, the technique yield of the intermediate plate can be well improved, and meanwhile, the production efficiency is improved.
Description
technical field [0001] The invention relates to a cooling structure, in particular to a mid-pan cooling structure. Background technique [0002] At present, domestic aluminum alloy wheels are usually manufactured by gravity casting or low pressure casting. Gravity casting is a casting method that fills the casting cavity with molten aluminum alloy by gravity to obtain castings, and the casting mold can be reused. When the center plate of the rim bottom mold is cooled, it is usually used to drill holes in the center plate, and at the same time weld the air duct on the center plate to align with the hole of the center plate. This method is air-cooled and requires a large amount of air, but the cooling effect But it is not ideal, resulting in long production cycle, slow solidification rate of aluminum water, coarse crystal grains, low tensile strength of the mounting surface, poor performance, need to re-make cooling, serious waste of cost.
