Abstract
A technology for preparing the internal decorative member of car, such as the one for steering wheel, includes such steps as preparing a stearing wheel from silica rubber, immersing in water polyurethane paint, heating to 150 deg.C for solidifying, immersing again, solidifying to obtain the external layer, turning it over, sleeve on skeleton, putting in mould, filling the foaming PU, solidifying, and demoulding.
Description
One, technical field:
The present invention proposes a kind of manufacture method of automotive upholstery, prepares the method for inside gadgets such as vehicle steering, seat cushion, handrail, headrest specifically.
Two, background technology:
At present, as the manufacture method of vehicle steering, mainly be with PU from the skinning material, the foam-in-mould moulding, high-grade vehicle steering coats corium again behind foaming.Foam-in-mould is manufactured steering wheel needs to take out of with discharging method mould inside in process air, the appearance that makes it goods not only has gate vestiges, also the steam vent vestige will be arranged, and overflows burr outside die joint, after deburring, stay sharp trace, had a strong impact on the presentation quality of goods.Material that the more important thing is discharge reclaims difficulty, forms a large amount of rubbish, contaminated environment, wastage of material, production cost height; Coat corium handwork, efficient is low, costs an arm and a leg.Before cast, must spray releasing agent in addition, pollute to working environment in cavity surface.
Three, technology contents:
The objective of the invention is to solve the problem and shortage that exists with background technology, is the method that there is the automotive upholstery that corium state or synthetic leather coat the outside of foamed state and propose a kind of inside.
Technical scheme I of the present invention
At first, make one with silicon rubber as required and have inverse textured steering wheel exemplar, be called master mold, be placed on and make it to rotate even dipping in the hopper that aqueous polyurethane coating is housed, take out then and heat to 150 ℃, make liquid coating be semi-cured state, and then put into hopper dipping, curing reaches the PU thickness that overlays on master mold exemplar top layer and peels crust about 1mm once more, turn over and make texture outside, be enclosed within and together be placed on the frame of handwheel in the mould, facing to the inside filling-foam PU material of the cast gate that is located at the goods shelter, solidify the back die sinking and take out finished product toward crust with PU foaming casting machine.
Technical scheme II of the present invention
With the steering wheel exemplar, be placed on than this steering wheel periphery to go out greatly in the resin die external mold of 4mm, under vacuum state, in the 4mm space of exemplar and mould, pour into a mould silicon rubber, treat to take out after 24 hours the exemplar that is surrounded by silicon rubber, the accurate cutting of inner ring at the steering wheel exemplar peels the silicon rubber crust, be enclosed within as internal mold and put into external mold on the frame of handwheel together, the dual-component polyurethane metering is injected the internal mold of mould with polyurethane elastomer casting machine by the cast gate that is located at the goods shelter, then mould is fixed on the special-purpose framework that can make its low speed rotation, make polyurethane evenly be covered with the internal mold surface, treat together to take out together with skeleton after two component PU reactions are solidified, be placed in the mould and expect with the inside filling-foam PU of PU foaming casting machine, solidify the back and take out finished product toward crust by hidden cast gate.
The present invention compares with background technology, the gadget of processing without discharge, without exhaust, no gate vestiges does not have the die joint vestige yet, because the master mold emulation that silicon rubber is made is splendid, so the presentation quality of goods can compare favourably with the corium goods; The mould usable resins is watered injection molding, needn't be with traditional metal die, and the process-cycle reduces by 2/3, and cost is 20% of a conventional metals mould.
Four, the specific embodiment
Embodiment 1
Manufacture automotive upholstery: steering wheel.Adopt silicon rubber to manufacture one as required and have the inverse textured steering wheel exemplar of corium, it is master mold: choice direction dish exemplar, inwardly wrap on the exemplar with the corium texture, be fixed on the framework that can produce low speed rotation, brush the PU elastomer to 5mm curing, side accurately together peels it together with corium after the cutting within it, is contained in then in the resin mold, choose poultry and solidified the back taking-up through 24 hours toward its inner injection silicon rubber with the large size syringe needle, master mold.
Apparatus for production line on the master mold is put into the stainless steel hopper that aqueous polyurethane coating is housed, make its low speed rotation of 5 rev/mins, evenly flood the steering wheel exemplar, it is master mold, take out then, enter heating cabinet, heat to 150 ℃, 15 minutes, make it liquid coating and be semi-cured state, the exemplar skin depth reaches about 1.5mm, can enter again in the aqueous polyurethane hopper and flood, take out solidify once more, heat 15 minutes 150 ℃, its PU thickness that is coated on the exemplar (master mold) is stabilized in about 1.5mm, with specific purpose tool accurately cutting peel crust, turn over make inner face texture outwardly, become the overcoat of the typing of emulation skin, be enclosed within again and put into mould on the frame of handwheel together, by being located at the cast gate in goods shelter,, inject filling-foam PU material toward the inside of crust with the PU casting machine that foams, wait to solidify the back die sinking and take out finished product, both be the steering wheel of emulation skin state.
Embodiment 2
Choice direction dish exemplar, putting into the resin die that goes out 4mm greatly than this steering wheel periphery is external mold, put into the casing that vacuumizes, under the state of vacuum, in the space of the 4mm of exemplar and mould, pour into a mould silicon rubber, treat to take out after 24 hours the exemplar that is surrounded by silicon rubber, inboard accurately cutting at the steering wheel exemplar, peel the silicon rubber crust as internal mold, be enclosed within on the frame of handwheel, be placed in the external mold, by being located at the cast gate in goods shelter, with polyurethane elastomer casting machine dual-component polyurethane is measured the internal mold that injects mould according to the product structure size, mould is fixed on the special-purpose framework that can make its low speed rotation, makes polyurethane be covered with the internal mold surface uniformly, two component PU reactions are solidified the back and are together taken out together with skeleton, be placed in the mould and expect with the inside filling-foam PU of PU foaming casting machine, wait to solidify the back and take out finished product toward crust by hidden cast gate.
, can manufacture equally with identical principle method as backrest, handrail, seat cushion, headrest and car door interior lining panel etc. automotive upholstery by above-mentioned technology, the method for its handrail and seat cushion also can be used for furniture industry.
