[0002] Foamed products are widely used in real life. The foamed products are made by foaming process. Foaming is a common manufacturing process, which can be used to manufacture foamed plastic products and can be applied to the packaging industry, the construction field, the automobile industry, electronic appliances and the like. Specifically, the foamed products can be applied to automobiles or other vehicles and used as interior decoration or other functional structures. Mold pressing foaming process is a common polymer foaming process, which is widely used in the fields of thermal insulation materials, structural materials and sound insulation materials in production. The principle of the process is to pour the foamed polymer prepared in advance into the cavity of the mold made under the conditions of high temperature and high pressure, and to form the shaped material by expansion and solidification. When the foamed piece is produced by using the mold pressing foaming process, mold pressing forming is needed. In the mold pressing forming, the powdery, granular or fibrous plastic is first put into the mold cavity at the forming temperature, and then the mold is closed and pressed to make it form and solidify.
