Problems solved by technology

[0008] One of the technical problems to be solved by the present invention is to provide a cover for the traditional car seat cover and foaming production process, which requires high labor costs for seat covering, frequent appearance problems, and easy wrinkling. One-piece foam structure without sewing
[0009] The second technical problem to be solved by the present invention is to provide a non-sewing integrated cover foam structure for the traditional car seat cover that needs sewing, high labor cost and low efficiency.
[0010] The third technical problem to be solved by the present invention is to provide a non-sewing one-piece face cover foaming structure in view of the problem that the traditional PIP technology is applied to large foam products, and the positioning of the foaming mold and the cover is difficult.

Embodiment 1

[0075] see Figure 1 to Figure 5 , the preparation process of the one-piece mask foam structure product of this embodiment is as follows:

[0076] 1) Prepare a number of concave molds 100 with a thickness of 3 to 5 mm according to the profile requirements of the side of the foam facing the occupant (hereinafter referred to as the A side of the foam);

[0077] 2) According to the profile requirements of the surface A of the foam body, several pieces of surface covering pieces 200 are cut;

[0078] 3) Place each block face cover cut piece 200 in the corresponding die 100 and use several I-shaped label nails 300 for positioning; the edges of the block face cover cut pieces 200 are all higher than the corresponding die 100 edge 5 ~10mm.

[0079] When using several I-shaped label nails 300 for positioning, punch holes at the key positions of the die 100 (positions with larger arcs, upper edge positions), select suitable sized javelins and I-shaped label pins 300, and the diameter...

Embodiment 2

[0085] see Image 6 , the difference between the preparation process of the integrated face cover foam structure product of this embodiment and embodiment 1 is that: the positioning between the block face cover cut piece 200 and the die 100 is positioned by glue, that is, inside the die 100 Apply a layer of adhesive film 310 (the adhesive film 310 is not easy to remain on the surface of the block face cover cut piece 200), put the block face cover cut piece 200, close the mold and start foaming, take out the product , removing the adhesive film 310 so as not to affect the appearance of the product. The remainder of this embodiment is the same as embodiment 1.

Embodiment 3

[0087] see Figure 7 , the difference between the preparation process of the integrated face cover foam structure product of this embodiment and embodiment 1 is that: the positioning between the block face cover cut piece 200 and the die 100 adopts several iron powder sheets 320 and some magnets 330 Positioning is carried out, wherein the magnet 330 is arranged on the die 100, and the iron powder sheet 320 is arranged on the block face cover cutting sheet 200. The specific method is to install a magnet 330 at the key position of the die 100 (the position where the radian is larger, the upper edge position), and when placing the block face cover cut piece 200, stick an iron on the back side of the block face cover cut piece 200 at the corresponding position. The powder sheet 320 fixes the block face cover cut piece 200 and the die 100 . The remainder of this embodiment is the same as embodiment 1.

[0088] The positioning between the block face cover cutting piece 200 and the...

Abstract

The invention discloses a sewing-less integral surface cover foaming structure, which comprises a foaming body and a surface cover attached to a surface of the foaming body facing to a passenger. The sewing-less integral surface cover foaming structure is characterized in that the profile of the surface of the surface cover facing to the passenger of the foaming body is divided into a plurality of surface cover tailoring pieces, and each tailoring piece of the surface cover and the foaming body are directly integrated by a PIP manner. The invention also discloses a mold and method for preparing the sewing-less integral surface cover foaming structure. The sewing-less integral surface cover foaming structure solves the problems that wrapping is required, a manual cost required for seat wrapping is high, an appearance problem is frequent, and wrinkles are easily generated in a production process of a traditional automobile seat surface cover and foaming, also solves the problem of high manual cost and low efficiency caused by a fact that the traditional automobile seat surface cover needs to be sewed, the problem of difficulty in location of the foaming mold and the surface cover since a traditional PIP technology is applied to large foaming products, and the problem that the traditional automobile seat production mode cannot meet customized requirements of a client.

Description

technical field [0001] The invention relates to the technical field of seats, in particular to a foaming structure of a non-sewing one-piece face cover, a preparation mold and a preparation method. Background technique [0002] The connection methods between the traditional car seat cover and the foam are mainly as follows: [0003] 1. The face cover and the foam are connected by means of Hog Ring (C-shaped ring), buckle and Velcro. This coating method requires a lot of labor, and the coating tolerance is large, it is easy to wrinkle, and the appearance of the manufactured product frequently occurs. [0004] 2. The face cover and the foam are bonded together by glue. This method has high manufacturing costs, and uses a large amount of glue to bond the cover to foam, which has a great impact on VOC in the car and is not environmentally friendly. [0005] 3. Prepare the one-piece mask foam by PIP (pour-in-place) method. This method is often used in small foam products such...
