Automotive trim
Technical field
The utility model relates to interior trim technical field, particularly relates to a kind of automotive trim.
Background technology
Middle and high end, market car sales volume sustainable growth at home, high-quality high-end product demand will constantly increase, and environment protection health theory is in fashion, automotive trim product also starts leading green concept, environment protection health series products is by a megatrend that is development of automobile, improve the room fit one's leisure and exercise demands design in car, improve the traveling comfort of taking, also by medium-to-high grade car, widely adopted.
Traditional automobile A, B post forming process are, by A, B post plastic part, are first to use Mold Making moulding, then by manually by coating viscosity glue on Plastic Parts, then bond with nonwoven fabrics and Plastic Parts, finally unnecessary nonwoven fabrics has been pruned away to this work.This process need carries out three steps and has operated, the one, injection mo(u)lding, the 2nd, coating viscosity glue covers nonwoven fabrics, the 3rd, prune nonwoven fabrics, in this process, will use harmful toxic solvent, not only to being coated with the operating personal of coating viscosity glue, be harmful to, also exist the problems such as aerial contamination to occur simultaneously, add narrow space in Automobile, cause the more serious of in-vehicle air pollution and peculiar smell, simultaneously, coating viscosity glue again after plastic piece shaping, the operation that nonwoven fabrics is pasted together with Plastic Parts is many, need personnel also many, long processing time, and the quality of pasting is unstable, form the expensive production model of the subquality.Meanwhile, aforesaid operations completes by artificial conveyor line, so each workman has just determined that to the skill level difference of work the quality of product is inconsistent.
Utility model content
The purpose of this utility model is for the technological deficiency existing in prior art, and a kind of automotive trim of processing simple and safety and environmental protection is provided.
For realizing the technical scheme that the purpose of this utility model adopts, be:
, comprising the Plastic Parts that fabric is connected with fabric injection moulding with described, described fabric comprises the tissue layer that the nonwoven layer that is connected with Plastic Parts injection moulding is fixedly connected with nonwoven layer with described.
Described Plastic Parts is A post, B post or the C post of automobile.
Described fabric thickness is at 1.2-1.4mm.
Described tissue layer thickness is at 0.4-0.6mm, and described nonwoven layer thickness is at 0.6-1mm.
The horizontal expansion rate of described fabric is at 30-35, directly to stretch ratio at 20-25.
Described fabric and the volume ratio of Plastic Parts are 1:8-10.
Compared with prior art, the beneficial effects of the utility model are:
The utility model adopts low-pressure injection molding technology in Plastic Parts injection mo(u)lding, it to be connected with fabric injection moulding in the lump, at mould inside, complete moulding and the combination of fabric and plasthetics, thereby greatly improved the input that production efficiency has reduced human cost, and because be that mould is produced, so the quality of each goods is the same; Low-pressure injection molding technology has lacked the application to glue simultaneously, so the pollution of goods environment is zero.
Accompanying drawing explanation
Figure 1 shows that automotive trim cross section structure schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, automotive trim of the present utility model comprises the Plastic Parts 1 that fabric is connected with fabric injection moulding with described, described fabric comprises the tissue layer 3 that the nonwoven layer 2 that is connected with Plastic Parts injection moulding is fixedly connected with nonwoven layer with described, wherein, described Plastic Parts is automobile A post, B post or C post.Certainly for other, fabric need to be on Plastic Parts, adhered to and also this structure can be adopted.Wherein, the nonwoven layer of described fabric can adopt glue to be fixedly connected with tissue layer, and taste fast can leave after connection.
; adopt low-pressure injection molding technology in Plastic Parts injection mo(u)lding, it to be connected with fabric injection moulding in the lump; at mould inside, complete moulding and the combination of fabric and plasthetics; thereby greatly improved the input that production efficiency has reduced human cost; and because be that mould is produced, so the quality of each goods is the same; Low-pressure injection molding technology has lacked the application to glue simultaneously, so the pollution of goods environment is zero.
Specifically, the low pressure injection formaing technique of plastic cement and fabric, that plastics are adhered to each other by mold injection and nonwoven fabrics, the product adhesive force producing is very strong, in use, will never come off and ftracture, and fabric is a decorative layer on automobile product surface, also there is good surface abrasion resistance simultaneously.Simultaneously because not needing to add any alite paste by being injected into after plastics high temperature melting in the process that after mold cavity, speed is cooling and nonwoven fabrics is bonding, can stop alite paste smell and produce workshop environmental issue while producing, and the environmental issue of automotive trim.
Further, plastic cement is to enter nonwoven layer, in region 4 as shown in Figure 1, together with fabric is closely adhered to plastic cement.But plastic cement cannot see through nonwoven layer and arrive tissue layer to avoid affecting outward appearance, and preferably, described fabric thickness is at 1.2-1.4mm, and wherein, described tissue layer thickness is at 0.4-0.6mm, and described nonwoven layer thickness is at 0.6-1mm.The horizontal expansion rate of described fabric is at 30-35, directly to stretch ratio at 20-25.Described plastic parts is by the engineering plastics injection mo(u)lding of GR series.
Meanwhile, for the interior trimming parts of different size and shapes, described nonwoven fabrics and the volume ratio of Plastic Parts are preferably 1:8-10, adopt the proportional arrangement of coupling, can guarantee gadget intensity and unified appearance.
To sum up, the utility model adopts low pressure injection formaing technique to make automotive upholstery, by Plastic Parts, injection moulding is connected with fabric, effectively avoided the excessive use of glue, the operation that simultaneously one-shot forming is pasted together plastic cement and nonwoven fabrics, saved secondary processing process, the appearance of the automotive upholstery of made is beautiful, environmental protection, and has greatly improved production efficiency.
The above is only preferred implementation of the present utility model; it should be noted that; for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
