Edge film lifting mechanism for sponge foaming forming

The utility model relates to the field of sponge foaming industry, and discloses an edge film lifting mechanism for sponge foaming forming. A reaction body is welded to the lower surface of an equipment body, buffer parts are fixedly connected to the two sides of the upper end of the outer surface of the reaction body corresponding to the equipment body, a main reaction container is arranged on the lower surface of the equipment body corresponding to the reaction body, the inner surface of the reaction body is correspondingly and movably connected with the main reaction container, and the inner surface of the reaction body is correspondingly and movably connected with a small reaction container. During use, the bottom of the container is made of a soft polymer material, the lower part of the container can be deformed during foam forming reaction of sponge, a medium is not influenced by the foaming reaction, and the foam forming characteristic of the sponge is diffused from the center to the outside, so that t
