The invention belongs to the technical field of composite material siliconizing, and particularly relates to a melt siliconizing device and method for a large-size thin-wall composite material product, the melt siliconizing device is divided into multiple areas to be assembled, demolding is easy, through cooperative use of an upper mold, a lower mold, a pressing plate, a telescopic structure and a rotating table, silicon powder stays around the product when being in a liquid state at high temperature, and the product quality is improved. The problem of poor density gradient uniformity of upper and lower parts due to sinking of the silicon powder in a liquid state at high temperature in the technological process can be effectively prevented, and the porosity and density uniformity of the product are effectively improved. 本发明属于复合材料渗硅技术领域，具体为一种大尺寸薄壁复合材料产品的熔融渗硅装置及方法，熔融渗硅装置分成多区域组装而成，脱模简单，通过上下模、压板、伸缩结构和旋转台配合使用，使硅粉高温呈液态时停留在产品四周，可有效防止工艺过程中硅粉高温呈液态时下沉存在上下部位密度产生梯度均匀性差的问题，有效提高产品孔隙率、密度均匀性。
