8. A processing method of inner and outer ornament hot-pressing gel edging and splicing structure, which aims at the inner and outer ornament hot-pressing gel edging and splicing structure as claimed in any one of claims 1 to 7, and is characterized by comprising the following steps:
rolling the PU soft foam, spraying water, and attaching glass fibers to two side surfaces of the PU soft foam;
laying base fabric, a plurality of PU soft bubbles, glass fiber and surface cloth from bottom to top;
adopting a cold material hot die form, feeding the layered and laid material into a pressing die, carrying out hot press molding, carrying out thinning treatment on the edge of the material, and cooling to obtain an ornament base material with an acute edge section;
and inserting the acute-angle edge of one ornament base material into the other ornament base material, performing secondary hot-press molding, and cooling and solidifying the two into a whole.
9. The processing method of the inner and outer trimming members with the hot-pressed gel edge and the inserting structure as claimed in claim 8, wherein: the ornament base material forming the acute angle edge can be used as a raw material to be inserted into a hierarchical material to be hot-pressed of another ornament base material, and the ornament base material is directly spliced into a whole after hot pressing.
10. The processing method of the inner and outer trimming members with the hot-pressed gel edge and the inserting structure as claimed in claim 8, wherein: the inserted ornament base material does not need to be thinned, or a groove is reserved so as to be matched and spliced with the ornament base material forming the acute-angle edge, and before secondary hot pressing, glue is coated on the splicing part.
