Description
Technical field
The present invention relates to a kind of vehicle body fittings, specifically a kind of automobile rear console box lid cover plate and manufacture craft thereof.
Background technology
Automobile rear console box lid cover plate be located in the automobile boot and be positioned at tire above, as the effect of decorating, beautifying boot, mainly be to be used to place article, and realize and other accessory overlaps better.The general design weight capacity of automobile rear console box lid cover plate is 100kg.The conventional manufacturing process of storage tank cover plate is behind the existing automobile:
1. adopt the material modified injection moulding body of PP, be coated with in the abutting edge with the 3M silane coupling agent (because of various adhesion agent PP is difficult to bonding, so to be coated with the 3M silane coupling agent, and 3M silane coupling agent price is rather stiff);
2. spray glue on the surface then, place a period of time;
3. cover plate is put into lower mould, again lining is carried out tensioner, moulding is carried out in the matched moulds pressurize, and depanning after the moulding is carried out manual cut edge by loose tool.
On the whole, prior art is carried out the work flow of lining by the loose tool cut edge after promptly adopting body injection moulding, lining to spray glue and body mold pressing, compression molding.The complex process though body injection moulding operation is few, product weight is big, and the cost height is difficult for realizing the car load lightweight; Cut edge behind the lining spray glue with after the body compression molding, operation is loaded down with trivial details and technology backward, mostly is artificial control, is prone to defective products.In addition, existing above-mentioned manufacturing process also exists shortcoming such as come unglued easily between cost of product height, Heavy Weight, lining and body, and production technology falls behind, and operation is various, and the smell of product can not satisfy the automotive regulation requirement.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of automobile rear console box lid cover plate, and the body of cover plate is high-density polyethylene material (abbreviating " HDPE " as), and lining adopts the PET needle punched non-woven fabrics.Sealing around the body, thickness is even, body hollow, and uniform reinforced rib and centre add two steel pipes, there are rope hook and drawstring in the back, have enough load bearing stengths and lighter weight, reinforced rib can prevent the top board warpage, nontoxic, tasteless, odorless characteristics that its material itself has simultaneously, product surface is covered with flannelette, can carry out sound insulation and sound-absorbing better, can realize the decoration effect, and its smell meet the requirement of relevant automotive regulation.
Another object of the present invention, the manufacture craft of above-mentioned automobile rear console box lid cover plate is provided, be to adopt the blow gas assistant formation, it is disposable bonding that blowing part body and lining utilize the molten condition of plastics to carry out, cross cutting is carried out on the border one time, its operation is simple, is easy to control, the product quality height.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of automobile rear console box lid cover plate is HDPE blowing body, and the outside is bonded with PET needle punched non-woven fabrics precoat; Described blowing body be around the osed top hollow structure, be evenly equipped with reinforced rib in the cavity.
Being separated by in the cavity of body is provided with steel pipe, and described automobile rear console box lid cover plate back is provided with rope hook and drawstring.
Described automobile rear console box lid cover forward end middle part is provided with nylon drawstring.
The present invention also provides the manufacture craft of above-mentioned automobile rear console box lid cover plate, it carries out according to the following steps order: mould die sinking → at cover half hangs up that the PET needle punched non-woven fabrics → fusion HDPE being blow molded into one pocket shape → mould matched moulds directly over the mould carries out the product pressurize simultaneously, put on the air → the dynamic model thimble pushes up to the dynamic model place, the bonding end face thimble in PE bottom surface is regained, and two faces that each thimble ejects are merged into a muscle → mold cools down and carry out product protection die sinking → assembling steel pipe and rope hook, drawstring, nylon drawstring.
As the optimization of manufacture craft provided by the present invention, described fusion HDPE is that HDPE is heated to 180-220 ℃ of gained.
Under this temperature, can realize the complete fusion of HDPE, guarantee to obtain the raw material supply of full-fusing state, may can doping not melt the state raw material in the raw material if temperature is low again, can cause unnecessary energy dissipation and temperature is high again, therefore selecting melt temperature is 180-220 ℃, can guarantee that material has preferable molten condition.
Product provided by the present invention is installed in the vehicle boot when using, connect adopt around overlap joint, the 10mm of lap-joint, reinforcement on width is strengthened the weight capacity of this product greatly.
Owing to adopted above-mentioned technical scheme, the present invention compared with prior art, obtained technological advance is:
The basic structure of product automobile rear console box lid cover plate provided by the present invention, lining plays to be decorated and effect attractive in appearance, the effect that muscle in the middle of the body and steel pipe play reinforcement, can make product reach the load-bearing effect better, reinforced rib can prevent the top board warpage simultaneously, drawstring makes this physical efficiency take out the replacing spare tyre, and hook can make the product upset, need not take out body and just can take out spare tyre.Manufacture craft provided by the present invention, it is bonding to utilize the plastics fusion to carry out the lining of cover plate and body, amplexiforms to compare with existing employing spray glue and has saved one procedure, cost-cutting, environmental protection low-carbon (LC).Its operation is simple, is easy to control, the product quality height.
The present invention is suitable for producing the cover plate of automobile rear console box lid, and product is installed in the vehicle boot when using, and is used for load-bearing, also has decoration, beautifies the effect of rear console box.
The present invention is described in further detail below in conjunction with Figure of description and specific embodiment.
