Foam cushion

Technical field

The utility model is related to a kind of springy foam cushion and its processing molds, and cushion especially by bus is Driver or motroist provide the condition comfortably and to lessen fatigue.

Background technology

When driving or riding in an automobile, when especially road is farther out or the time is longer, people often add a seat on seat Pad increases comfort, lessens fatigue.Resilient foam cushion common now mostly be using molding foamed plastics as core, outsourcing with Fabric（Cloth）The housing of sewing.Although such cushion can be practical, its manufacturing process is complicated, labour intensive degree is high, Production efficiency difficulty improves, and cost difficulty reduces.The utility model then provides a kind of foam cushion, and fabric is with foamed plastics primary It combines and shapes in foaming operation..

Utility model content

The utility model is to overcome drawbacks described above, provides a kind of foam cushion, which includes being made of foamed plastics Ontology, the surface layer epithelium of the bottom surface as the positive textile fabric of the cushion, and as the cushion, wherein as just The textile fabric in face with the foam body is combined by binder；Surface layer epithelium as bottom surface is in the bubble What the bottom surface of foam plastic body was formed.

Wherein, the binder is that for fitting to that the preparation of the textile fabric combined with the foam body On one side, it is then combined with the foam body.

Wherein, the front of the textile fabric, weaving have, are printed with or embroider and have layout.

Wherein, there is the recessed of solid in the front of the cushion, the foam body and together with the textile fabric Convex moulding.

The utility model also provides a kind of mold of manufacture foam cushion, which includes the foamed plastics to form the cushion The mould body of ontology, forming the fixed tight loop of the positive fabric of the cushion and seal the mold and carry out foam moulded Die cap, wherein there are the die face of the mould body a plurality of air holes, each air hole to be communicated to an evacuation space, and the evacuation is empty Between there is exhaust tube to be connected to sucking pump, and wherein, the mould body is provided with circulation heat or cold liquid so that this is heated or cooled The register of mold or product temperature.

Wherein, the position of the mold is contacted and sealed with the mould body in the die cap, be arranged accurate chimeric superfluous to cut off The sharp edge of remaining material.

Wherein, circulation heat or cold liquid are also equipped in the die cap so that the mold or product temperature is heated or cooled Register.

Wherein, the mold is provided with the device of fastening sealing power after mold sealing.

Wherein, the device of the fastening sealing power is the fastening spring being sleeved in fastening bolt.

Specific implementation mode

In the present invention, described " front " refers to the side that user takes；Described " bottom surface " refers to In use, the side that the cushion is contacted with original seat surface.

Fig. 1 is the schematic diagram of the foam cushion 1 of the utility model.It includes：

As the foamed plastics 2 of cushion, preferably with polyethers and '-diphenylmethane diisocyanate（MDI）For major ingredient Open-cell flexible foam plastic；

As the textile fabric 3 of cushion front face surface, polyester fiber fabric is preferably used, it is more preferable with the fabric of knitting, The moulding being easy to product surface is profile-followed.Before foam moulded operation, in advance at the back side of fabric 3（That is, and foam mould Mould the side combined）It is bonded a layer of adhesive film 4, preferably with the polyurethane with excellent adhesive performance（PU）Film.One The function of layer binder film 4 will also weaving in addition to so that foamed plastics 2 bonding of the textile fabric 3 with molding is become an entirety Product fabric 3 becomes airtight so that when the front of textile fabric 3 is attached in die face 31 and starts sucking pump, makes spinning Fabric fabric 3 smooth in die face 31 can be adjacent to.

The bottom surface of cushion 1 is surface layer epithelium 5.The formation of surface layer epithelium 5 is mouldable slurry（It is preferred that using can The rubber of thermoplastic, i.e. TPR）It is coated in the surface of die cap 23（In advance releasing agent has been applied on the surface of die cap 23）, wait for it and carry out mould Modeling（Foaming）The foamed plastics of reaction contacts, i.e., it is heated and on the surface of foamed plastics（Bottom surface）The epithelium of a thin layer is formed, The namely bottom surface of finished product cushion 1.In this way, finished product cushion 1 has the perfect surface layer epithelium 5 of appearance, do not make foamed plastics Material is exposed outside.

The front of textile fabric 3, the layout that the upper user that can weave, prints or embroider needs.

The front of cushion 1 can manufacture solid on demand（3D）Concave-convex moulding 6.In the thin portion of moulding 6, fabric 3 and bubble Foam plastics 2 are still in conjunction with integral.

The partial enlarged view connected by dotted line 80,81, can see more clearly.

Fig. 2 is the schematic diagram of the mold 20 for the foam cushion for manufacturing the utility model.It includes：

Mould body 21；It include the die cavity 30 in the formation space as cushion 1；There is die face 31 within die cavity 30；Have in die face 31 Many intensive air holes 32, the another side of die face 31 are to evacuate space 33, and sucking pump is connected to by exhaust tube 34（Vacuum Pump）；Being bonded adhensive membrane（That is, adhesive layer 4）The front of textile fabric 3 be attached in die face 31, start air exhauster Tool makes textile fabric is smooth in die face to be adjacent to；The air hole 32 of die face 31 needs correctly to design, and aperture can not be excessive, with Exempt from fabric recessed air hole in die face, finished product is made to carry bulge.Mould body 21 has also needed to thermoregulating system, is temperature adjustment folder in this figure Set 35（It other can also design）, there is liquid（Water）Inlet/outlet pipe 36；Use hot water（Or high steam）, or use chilled water （Or refrigerant）Cycle mold is heated or cooled, meet heating or the cooling needs of moulding technology（Arrow 85,86 indicates stream Dynamic direction）.

Tight loop 22；For tightening, fixing the textile fabric 3 being attached in die face 31 has been inhaled, it is 37 to tighten contact surface With 37 ', and indicated by dotted line 84.Label 38 indicates the entity border of tight loop.

Die cap 23；There is mould bottom surface 39, exactly forms the position of the bottom surface surface layer epithelium 5 of cushion 1.Die cap 23 and 21 envelope of mould body When conjunction, the edge 37 ' of mould bottom surface 39 ' be pressed onto mould body 21 oral area seal face 37, seal, this is indicated by dotted line 83.Such as Fruit makes accurate chimeric sharp keen arris in sealing contact surface 37 and 37 "（It is not shown in figure this structure）, then in foaming And the product after depanning, the material of redundancy is cut off automatically, saves the workload manually trimmed.To reach this effect, need Molding compaction degree is kept in foamed forming process；The device for sealing power is fastened after sealing is provided, for example, using fastening bolt is sleeved on On fastening spring（It is not shown in figure）.

The manufacturing method of the foam cushion of the utility model includes following step：

（1）It is bonded the adhensive membrane of thin layer at the back side of textile fabric；

（2）In the surface spraying releasing agent of mould body and die cap contacted with product；
