a first positioning plate 12 located on a side of the positioning surface 113 away from the placement surface 111, wherein the first flexible mold body 11 is fixed to the first positioning plate 12 via at least a portion of the positioning surface 113 thereof;

the extrusion assembly 2 is positioned on one side of the first flexible die body 11 away from the first positioning plate 12, wherein the interval between the extrusion assembly 2 and the first positioning plate 12 is adjustable, and the extrusion assembly 2 is suitable for extruding the first flexible die body 11 positioned between the extrusion assembly 2 and the first positioning plate 12.

It is easy to understand that in actual production, the specific shapes of the placement surface 111 and the mold body side surface 112 of the first flexible mold body 11 need to be determined according to the shapes of the inner cavities of different products 3, so as to ensure that the first flexible mold body 11 can better fit the inner cavities of the products 3.

In detail, in this embodiment, the product 3 may refer to a mobile phone case. In other embodiments, the specific type of the product 3 is not limited, and may be, for example, a notebook casing, a tablet casing, or other related products requiring auxiliary materials for lamination.

In this embodiment, in order to facilitate the attachment of multiple auxiliary materials in the inner cavity of the product 3, the number of the first flexible mold bodies 11 is set to 1, and the size of the first flexible mold bodies 11 is slightly smaller than that of the inner cavity of the product 3.

In other embodiments, the number of the first flexible mold bodies 11 may be multiple, that is, the first flexible mold bodies 11 with appropriate sizes may be set at multiple positions where auxiliary materials need to be attached in the inner cavity of the product 3, meanwhile, a corresponding number of first positioning plates 12 may be set, the auxiliary materials in each position in the inner cavity of the product 3 may be attached by extruding the first flexible mold bodies 11 matched with each first positioning plate 12 through the extrusion assembly 2, and of course, only 1 first positioning plate 12 may be set to simultaneously correspond to the multiple first flexible mold bodies 11 for extrusion.

Specifically, the first positioning plate 12 is mainly used for limiting the first flexible die body 11, and the space between the first flexible die body 11 and the first positioning plate 12 is adjusted through the extrusion assembly 2, so that the first flexible die body 11 between the extrusion assembly 2 and the first positioning plate 12 deforms under the action of extrusion forces on two sides, and the first flexible die body 11 expands around the inner cavity of the product 3 in the direction perpendicular to the extrusion direction.

In an exemplary embodiment, when the inner cavity of the product 3 is rectangular, that is, the product 3 has four inner cavity sides 32, the placement surface 111 of the first flexible mold 11 may be used to press the auxiliary materials on the bottom surface 31 of the inner cavity of the product 3, and the four mold sides 112 of the first flexible mold 11 may be used to press the auxiliary materials on the four inner cavity sides 32 of the product 3 respectively by using the expansion of the periphery of the first flexible mold 11 when the first flexible mold 11 is pressed.

In this embodiment, the plate surface of the first positioning plate 12 is larger than the positioning surface 113 of the first flexible mold body 11, and the positioning surface 113 of the first flexible mold body 11 completely covers the plate surface of the first positioning plate 12, so that the first flexible mold body 11 can be completely deformed under the relative extrusion of the first positioning plate 12 and the extrusion assembly 2 under the action of the extrusion assembly 2.

Of course, in other embodiments, only a partial deformation of the first flexible mold body 11 may occur. That is, the plate surface of the first positioning plate 12 may be smaller than or equal to the positioning surface 113 of the first flexible mold 11, so that the first flexible mold 11 is deformed.

The auxiliary material pressing jig provided by the embodiment comprises a first flexible die body 11, a first positioning plate 12 and an extrusion assembly 2.

It is easy to understand that the shape and the size of the second profiling mold body 21 are adapted to the shape and the size of the outer surface of the product 3 far away from the bottom surface 31 of the inner cavity, so as to ensure that the contact area between the second profiling mold body 21 and the product 3 is maximized, so that the stress generated to the product 3 when the extrusion assembly 2 is pressed to the product 3 is dispersed, and the probability of damaging the product 3 when the extrusion assembly 2 is pressed is reduced.

Further, the second profiling mold body 21 is made of a flexible material, so that the product 3 is prevented from contacting the second profiling mold body 21 made of a hard material, the second profiling mold body 21 is located between the first flexible mold body 11 and the second positioning plate 22, and the second profiling mold body 21 can provide buffering for the outer surface of the product 3 far away from the bottom surface 31 of the inner cavity when the extrusion assembly 2 works, namely, the second profiling mold body 21 is used for preventing the product 3 from being damaged and deformed when the extrusion assembly 2 works. In this embodiment, the material of the second profiling mold body 21 is the same as that of the first flexible mold body 11, and silica gel with the shore hardness of 60-65 degrees is adopted, so that the second profiling mold body 21 has the same technical effect as that of the first flexible mold body 11, and the details are not repeated here; in other embodiments, the second contoured mold body 21 may be formed from a flexible material such as rubber, sponge, or the like.
