[0004] This solution still has some shortcomings in application. Since the foaming board needs to be heated and melted during the self-blowing foaming molding process, the mold is in a high temperature state after molding. It is necessary to wait until it cools down before removing the mold. This will waste a lot of time and is not conducive to production efficiency. At the same time, since the mold needs to be replaced according to different needs, if the mold is fixed, the mold needs to be disassembled, replaced and fixed for molding different products. This will also waste a lot of time and is also not conducive to production efficiency. Therefore, it is necessary to improve the structure of the molding device to facilitate mold replacement, and at the same time, the molded products can be automatically conveyed to improve the automation level of the molding device.
