Shoe forming method

A product molding method, comprising the following steps:

• (1) placing a film on a substrate mold, and fixing the film between the substrate mold and a middle frame;
• (2) placing an outer husk material on the film, sucking the film to sag in towards the substrate mold, attaching the film to a bottom of the substrate mold, holding for 0-5 min, and performing primary curing molding to obtain a molded outer husk;
• and
• (3) placing an inner core material in the molded outer husk, performing secondary curing molding to obtain a molded inner core, and releasing the molded inner core to obtain the product,
• the outer husk material is placed on the film and then the film is sucked, as the film sags in towards the substrate mold, the outer husk material flows with a deformation of the film, forming an outer husk material layer in a hollow of the film;
• the outer husk material wraps a side and bottom of the inner core material;
• wherein the outer husk material has a melt viscosity of 1000-5000 mPa/s at 20-450C.
