Abstract
The present invention relates to a kind of automobile door protection panels to cover subsidiary formula method, by glue by epidermis it is close, smooth be attached on automobile door protection panel plastic skeleton, beautiful, good visual effect automobile door protection panel inside gadget has been made, this method significantly reduces die cost and product appearance risk, using on Mr. Yu's domestic automobile and achieving preferable economic benefit.
Description
Technical field
The present invention relates to technical field of automobile parts, and in particular to a kind of plate of car door shield covers subsidiary formula method.
Background technology
Under the trend of automotive light weight technology, more and more automotive upholsteries replace original metal using engineering plastics
Or leather upholstery, this method both alleviates weight, and more beautiful, of low cost, machine-shaping is conveniently.With life water
Flat raising and the transformation of consumption idea, people pursue more and more high-grade automotive trim, also more next to its surface quality requirements
It is higher, the feeling that beautiful air improves grade visually is showed, any small flaw can all influence user experience.
Automotive upholstery is broadly divided into Soft Roll and Hard Roll, and wherein Hard Roll is since surface is susceptible to defect and is also easy to produce cheap
Sense, therefore the ratio used is lower and lower；And existing Soft Roll technique is typically to attach expanded material on substrate, for letter
List, small-sized inside gadget effect are preferable, and bad for the covered effect in large-scale, complicated face, and cost is higher.
Invention content
It is an object of the invention to overcome the above problem of the existing technology, a kind of illiteracy subsidiary formula of automobile door protection panel is provided
Method.This method can not only reduce the appearance requirement to plastics inside gadget, and die cost is also greatly saved, and cover attached
Automobile door protection panel apparent visual effect is good, and fitting is close between layers, suitable for various complicated, large surfaces, greatly drops
The low appearance risk of inside gadget, has adapted to the market demand.In order to achieve the above object, the technical solution adopted in the present invention is such as
Under：
A kind of illiteracy subsidiary formula method of automobile door protection panel, includes the following steps：(a) first formed automobile door shield plastic skeleton and
Epidermis of corresponding size is spare；(b) automobile door protection panel plastic skeleton outer surface and epidermis inner surface are cleaned out simultaneously respectively
Even glue spraying；(c) epidermis illiteracy is attached on automobile door protection panel plastic skeleton, two glue spraying faces are in close contact and apply certain pressure holding
Certain time；(d) after the glue solidifies, glue is made to be flattened repeatedly after melting epidermis edge heating；(e) it is cuticular border is intermarginal disconnected
Point, which is welded in the automobile door protection panel plastic skeleton back side, makes it fix to obtain the final product.
In said program, the automobile door protection panel plastic skeleton is molded by PP, and the key parameter of injection molding is：It penetrates
200 ± 10 DEG C of mouth temperature, injection process：First segment 65mm/s, 80Bar, 80mm；Second segment 50mm/s, 80Bar, 60mm；Pressurize
Process：Speed 20mm/s, pressure 80Bar, time 3.5s；Cooling time 30s ± 1s.
In said program, the epidermis is PU material, is made by extrusion molding.
In said program, the glue of glue spraying is adhesive sticker, and glue spraying amount is respectively 0.1g/cm2, need to ensure to spray full nothing everywhere
Drain spray, but should not the amount of being jetted through lead to out-of-flatness.
In said program, the pressure that epidermis illiteracy is attached to after-applied 30N or so on automobile door protection panel plastic skeleton keeps 3-5s.
Epidermis edge is heated to 80 DEG C or so in said program, after the glue solidifies melts glue, repeated multiple times by table
Skin flattens.
In said program, every 20mm spot welding after the flattening of epidermis edge, it is made to be fixed on the automobile door protection panel plastic skeleton back of the body
Face, natural cooling to obtain the final product.
Compared with prior art, the invention has the advantages that：(1) to automobile door protection panel plastic skeleton technological requirement
It is not high, die cost can be greatly lowered；(2) it is smooth, firm to be bonded between epidermis and skeleton, and apparent visual effect is good, is applicable in
In the inside gadget of various different complex models；(3) cost is relatively low, has been used in certain MPV project that certain vehicle enterprise releases, the vehicle
2.5 ten thousand sets of annual output, life of product are 5 years, subsequently can also persistently change money, the economic profit brought is very big.
Description of the drawings
Fig. 1 is that automobile door protection panel of the present invention covers attached design sketch.
Specific embodiment
For those of ordinary skill in the art is made to fully understand technical scheme of the present invention and advantageous effect, below in conjunction with specific
Embodiment is further described.
Embodiment 1
First with PP and PU materials, automobile door protection panel is made by injection molding process and extruding-out process respectively and is moulded
Expect skeleton and epidermis of corresponding size.Automobile door protection panel plastic skeleton injection-mold process parameter is：Nozzle temperature 200 ± 10
℃；Injection process：First segment 65mm/s, 80Bar, 80mm；Second segment 50mm/s, 80Bar, 60mm；Pressure maintaining period：Speed
20mm/s, pressure 80Bar, time 3.5s；Cooling time 30s ± 1s.
Then automobile door protection panel plastic skeleton outer surface and epidermis inner surface are cleaned out, and it is uniform to spray last layer
Adhesive sticker, glue spraying amount are 0.1g/cm2.Glue spraying process directly affects and finally covers attached effect, and not firm enough the easy production of bonding has been lacked in spray
Raw hollowing has been sprayed and be easy to cause thickness everywhere differed, total principle：Spray is full without drain spray everywhere.
Epidermis illiteracy after sizing is attached on automobile door protection panel plastic skeleton by third step, and two glue spraying faces are in close contact and apply
Pressure pressurize 3s of about 30N or so.After the glue solidifies at epidermis edge flange, automobile door protection panel plastics bone is heated with grilled gun
Frame edge melts glue to 80 DEG C or so, repeated multiple times to flatten epidermis.After epidermis edge flanging panning, in automobile door protection panel
The plastic skeleton back side is primary every 20mm spot welding, and epidermis is made to be fixed on the strong degree for improving edge on plastic skeleton.Treat entirety certainly
It is so cooled to room temperature, just completes and cover attached technique, quality inspection qualification, that is, referable user uses.
For certain MPV that certain vehicle enterprise releases using after the technique, 2.5 ten thousand sets of yield, life of product is 5 years, subsequently can also be held
It is continuous to change money, bring objective economic profit.Color and the form variation of epidermis are more, and combination can form miscellaneous interior trim
Part, the technique are also applied for other automotive upholsteries.
