Abstract
The invention relates to a manufacturing process of a soft dashboard, which is characterized in that first of all PP material or ABS material is used as the raw material, the framework of a dashboard is injected and molded; then a PVC or ABS or TPO skin sheet which is pasted with a PU or PE or PP foaming layer at the backside is absorbed by the way of vacuum plastic-absorption and is pasted by the paste agent at the surface of the framework of the dashboard, so the three layers structure of the soft dashboard that the surface layer is the PVC or ABS or TPO skin, the middle layer is the PU or PE or PP foaming layer, and the other side is the framework of the dashboard is formed. The manufacturing process can effectively solve the problems that the equipment investment is large, the production cost is high, the process is complex, and the foaming pollution exists, etc. in the manufacture of the prior soft dashboard, the production cost is greatly reduced, and the process course is simplified.
Description
Technical field
The present invention relates to the manufacturing process of the soft instrument panel of automotive trim, a kind of manufacturing process that is particularly suited for being applied in the soft instrument panel in the middle and high shelves car of more specifically saying so.
Background technology
At present, known soft instrument panel is by plastic skeleton, and the three-decker of PVC, ABS or TPO epidermis and PU, PE or PP foaming layer bonds together composition.Its basic technology is at first with PP or ABS class material feedstock, parts such as injection mo(u)lding instrument board framework, make PVC separately by vacuum forming or slush moulding mode, ABS or TPO epidermis, on foaming mould, place instrument board framework and epidermis again, in mould, fill liquid blowing agent (PU, PE or PP material), matched moulds a period of time waits for that blowing agent solidifies, form the soft instrument panel three-decker of epidermis+foaming layer+skeleton, pass through cutting action thereafter, cut the epidermis at unnecessary slitter edge and place, cavity, and adopting the method for welding that the part injection-moulded plastic part is welded on the instrument board framework, other annex also is installed in the lump finishes assembling on the instrument board framework.But, this technical process meets the curved surface epidermis of instrument board complexity and the moulding of the foaming layer between epidermis and plastic skeleton owing to relate to independent manufacturing, and complex technical process needs to use a lot of expensive special equipments, the production cost height has in the foaming process to pollute to produce.
Be CN1775580, be to disclose a kind of fascia and manufacture method thereof in the patent application specification on May 24th, 2006 in open day at publication number.This instrument board body comprises the epidermal area that is positioned at the body top layer, and the material of epidermal area is a thermoplastic polyolefin elastomer, and the outer surface of epidermal area is provided with decorative pattern; What be positioned at the body bottom has a body skeleton, and the material of body skeleton is a polypropylene; Between epidermal area and body skeleton and the intermediate layer that bonds them together be that polyurethane foam forms.The manufacture method of this instrument board body remains at first moulding epidermal area and body skeleton respectively, foams in mould, to be formed on foaming layer between epidermal area and the body skeleton with the three-decker molding bonded again.As previously mentioned, this method is because of relating to curved surface epidermis and the foam process that independent manufacturing meets the instrument board complexity, thereby production process complexity, cost height, exists in producing and pollute.
Summary of the invention
The present invention is for avoiding above-mentioned existing in prior technology weak point, provide a kind of equipment investment little, and production cost is low, and technology is simple, the manufacturing process of the soft instrument panel of production process contamination-free.
The manufacturing process of soft instrument panel of the present invention is carried out as follows:
Be raw material at first with PP or ABS class material, the injection mo(u)lding instrument board framework;
Then the back side is pasted with PVC, the ABS of PU, PE or PP foaming layer or method absorption that TPO epidermis sheet material adopts vacuum forming and the surface that sticks on described instrument board framework with alite paste, formation is the top layer with PVC, ABS or TPO epidermis, with PU, PE or PP foaming layer is the intermediate layer, and opposite side is the soft instrument panel three-decker of instrument board framework.
After finishing above-mentioned moulding, repair the instrument board edge in the mode of cutting again, and the through hole on the moulding relevant position.
Adopt the mode welded and installed of Plastic Welding on the correspondence position of instrument board framework with parts the instrument board of each injection mo(u)lding of having got ready; Again other each annexes are installed on the instrument board framework.
The characteristics of manufacturing process of the present invention also are:
Described alite paste is coated on the surface of instrument board framework; Before pasting, the sheet material and the surperficial instrument board framework that is coated with alite paste that at first the back side are pasted with the epidermis of foaming layer heat respectively, and the sheet material heating-up temperature of its mesocuticle is at 90-130 ℃, and the heating-up temperature of instrument board framework is 50-90 ℃.
Keep vacuum state firmly in the described vacuum forming process until the binding agent bonding.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, the present invention has avoided independent manufacturing to meet the complex-curved epidermis of instrument board, and the direct adsorption forming of curved surface that utilizes ready-made instrument board framework surface to form has the epidermis of foaming layer, save the expensive special equipment and the precision die that are provided with for this reason, reduced production cost effectively.
2, the present invention has saved to have and has polluted the foaming operation that produces, and need not use expensive foaming production line, has further reduced production cost, simplifies technical process, has avoided the generation of polluting.
3, the present invention's mode of adopting vacuum forming is the coincideing of top layer that has foaming layer and instrument board framework, and its degree of agreement is good, and percent defective is low, can guarantee the Forming Quality of product effectively.
Description of drawings:
Fig. 1 is the functional-block diagram of technical process of the present invention.
Fig. 2 is the epidermis sheet structure schematic diagram of the band foaming layer of the present invention's use.
Fig. 3 is the instrument board generalized section of moulding of the present invention.
Number in the figure: 1 epidermis, 2 foaming layers, 3 instrument board frameworks.
Below by the specific embodiment, the invention will be further described in conjunction with the accompanying drawings:
The specific embodiment:
All plastic items that at first comprise instrument board framework with PP or the injection mo(u)lding of ABS class material feedstock;
The heating back side is pasted with PVC, ABS or the TPO epidermis sheet material of PU, PE or PP foaming layer, and heating scribbles the surface of the instrument board framework of adhesive; The sheet material heating-up temperature of its mesocuticle 1 is at 90-130 ℃, and the heating-up temperature of instrument board framework 3 is 50-90 ℃.
The Plastic Instrument Board skeleton 3 that heats is positioned on the plastics suction mould in the vacuum tank of upper opening, the sheet material of the epidermis 1 that heats moves to the top of instrument board framework 3, and it is suitable for reading and compress to cover vacuum tank, and vacuum tank is sealed; Utilize vavuum pump to take out the interior air of vacuum tank, the epidermis sheet material pressure dressing that makes the back side be pasted with foaming layer is being designed on the instrument board framework of all kinds of cambered surfaces, keeps vacuum state until the binding agent bonding firmly.In order further to quicken bonding speed, can adopt spraying or air blowing to lower the temperature.
