Embodiment 1

[0023] A 3D shaping device for non-woven fabrics for car seat foaming, comprising: an upper mold 1, a lower mold 2 and a negative-angle side pressing mold device;

[0024] like figure 1 As shown, a plurality of concave structures are distributed on one side of the upper mold 1;

[0025] like figure 2 As shown, a plurality of convex structures are distributed on one side of the lower mold 2;

[0026] The upper and lower positions of the upper mold 1 and the lower mold 2 are opposite to each other, and are used in conjunction;

[0027] The negative angle side pressing die device is connected to one side of the upper die 1 and the lower die 2, and mainly includes: a telescopic unit 31, a guide rod 32, a negative angle pressing block 33, a moving plate 34 and a connecting rod 35;

[0028] like figure 1 As shown, the moving plate 34 is located on one side of the upper mold 1, and is parallel to the upper mold 1;

[0029] One end of the upper mold 1 is connected with two guide...

Embodiment 2

[0033] The 3D shaping device for non-woven fabrics for automobile seat foaming as described in the first embodiment, the shaping method is as follows:

[0034] ①In the initial state, the negative angle pressing block 33 is far away from the upper die 1 .

[0035] ② In the next step, the non-woven fabric is transferred between the upper mold 1 and the lower mold 2, and the pressing between the upper mold 1 and the lower mold 2 is controlled, and the non-woven fabric is shaped at this time.

[0036] ③ In the next step, the telescopic unit 31 pushes the moving plate 34 and drives the negative angle pressing block 33 to run toward the lower mold 2. When the negative angle pressing block 33 is completely pressed with the lower mold 2, it stops, and the non-woven fabric will form the required negative angle structure.

[0037] ④ In the next step, wait for a certain amount of time. After the non-woven fabric is completely formed, the negative angle pressing block 33 moves in the opp...

Abstract

The invention relates to the technical field of non-woven fabrics, in particular to a 3D sizing device and production method for non-woven fabrics for foaming automobile seats. The non-woven fabric 3D sizing device for automobile seat foaming comprises: an upper mold, a lower mold and a negative angle side pressure mold device; a plurality of concave structures are distributed on one side of the upper mold; There are multiple convex structures distributed on one side of the lower mold; the negative angle side pressure mold device is connected to one side of the upper mold and the lower mold, and mainly includes: a telescopic unit, a guide rod, and a negative angle pressing block , moving plates and connecting rods. The invention solves the problems that the existing non-woven fabric has a low degree of fit with the mold and cannot produce negative angles.

Description

technical field [0001] The invention relates to the technical field of non-woven fabrics, in particular to a 3D sizing device and production method for non-woven fabrics for foaming automobile seats. Background technique [0002] Non-woven fabric is a new generation of environmentally friendly materials. It has the characteristics of moisture-proof, breathable, flexible, light, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, low in price, and recyclable. Non-woven fabrics are widely used in automobiles, and have gradually replaced the raw materials of many materials such as car interiors and sound insulation cotton. At present, the non-woven fabrics used in car seats are sewn from ordinary non-woven materials, or produced by simple molding to produce a simple 2D effect shape, which will have the following problems: [0003] 1. The non-woven fabric has a low degree of fit with the mold, the process is complicated, and the production efficienc...
