Detailed description of the invention
Involved in the present invention to structure have patrix 1, counterdie 2, open-work 3, upper model cavity 4, counterdie die cavity 5, vaccum suction pipe 6, vacuum generator 7, wind-guiding net 8, screen cloth 9, counterdie injection molding channel 10, patrix hot flow path 11, patrix cooling water pipeline 12, counterdie cooling water pipeline 13, die joint 14, wind-guiding network interface card 15, framework 16.
In order to realize the manufacture craft of sedan limousine wind-guiding net of the present invention, the present invention provides the particular manufacturing craft of car wind-guiding net especially.Concrete structure is as follows:
Particular manufacturing craft of the present invention is made up of patrix 1 and counterdie 2.
As Fig. 1---as shown in Fig. 3, the structure of patrix 1 is: the structure of patrix 1 is: in die face, be provided with along its length model cavity 4 in twice, described patrix is built-in with patrix cooling water pipeline 12, and described patrix top is provided with patrix hot flow path 11.
Upper model cavity 4 structures are: have along its length twice groove, be bent downwardly and be 15 ° at these groove both ends, be also provided with projection in inside grooves;
Counterdie 2 structures are: die face is provided with a geometric form counterdie die cavity 5, is provided with counterdie cooling water pipeline 13 in counterdie, and counterdie die cavity 5 communicates with upper model cavity 4;
The structure of counterdie die cavity 5 is: have along its length twice groove, be bent downwardly and be 15 ° at these groove both ends;
The structure of vacuum generator 7 is: comprise air inlet, impeller, water ring, exhaust outlet, rotor, the pump housing; The eccentric rotor of fixed blade is housed in vacuum generator 7, liquid is thrown to pump body lumen wall, form water ring, because centrifugal force forms a space in the pump housing, this space is divided into by impeller the loculus that lobe numbers is equal, and before vane rotary, the volume of loculus changes from small to big, and communicate with the air inlet on section, now air-breathing, at the end air-breathing, loculus and air inlet are isolated; In the time that impeller continues rotation, loculus from large to small, makes gas compressed; In the time that loculus communicates with exhaust outlet, gas is just discharged from.
The structure of the die joint 14 of upper and lower mould matched moulds is the face at the lower plane place of upper model cavity 4 internal projection.
When wind-guiding net is produced, wind-guiding network interface card 15 and wind-guiding screen frame frame 16 the first half are in the interior moulding of patrix 1, framework 16 the latter halfs are lower in-molded, the condensation of 9 process rubber of screen cloth is as a whole with 16 one-tenth of frameworks, detailed process is: PUR is injected from patrix injection moulding pipeline, be divided into two die cavities that two injection moulding pipelines form with upper and lower mould respectively and be connected, open cooling water pipeline, carry out cooling to the PUR flowing in die cavity.
In the time carrying out the making of wind-guiding net with above-mentioned upper and lower mould, because wire side is laid in mould, mould when matched moulds and Job Operations, will make screen cloth folding in grinding tool under external force because of carelessness, causes substandard products.
In order to solve the problem of wind-guiding net laminating, the present invention has carried out the design of structure to counterdie 2, has connected vacuum generator on counterdie, and on screen cloth, has added a cover thin film, and specific design is:
A kind of car wind-guiding net particular manufacturing craft, formed by upper and lower two moulds, this bed die 1 has some open-works 2 with wind-guiding net 5 corresponding positions to be processed, open-work 2 is distributed under whole plane to be processed, open-work 2 is toroidal near wind-guiding net one 5 sides to be processed, opposite side is connected in a vaccum suction pipe 3, and this vaccum suction pipe 3 is connected with vacuum generator 4; Each open-work 2 is connected with vaccum suction pipe 3 that to converge be that suction pipe is derived, and this suction pipe is threaded connection the air inlet in vavuum pump; Use after above design, vacuum generator 4 passes to negative pressure of vacuum to the open-work 2 on mould, apply a downward pressure to automobile wind-guiding net 5 to be processed, in addition, open-work 2 is made horn mouth and has been increased screen cloth lifting surface area, make screen cloth 6 better be close to mould 1 surface, and can move arbitrarily and pull screen cloth 6 and make its centering location, avoid screen cloth 6 off normals maybe can not take shape in the generation of sizing material phenomenon, effect is remarkable, in addition can also on screen cloth, add the airtight film of lid layer, more strengthen suction-operated.
Providing on special mold foundation, the manufacture craft of sedan limousine wind-guiding net of the present invention is specific as follows:
1, first clear up foreign material, gel residual on mould is removed, then coated releasing agent.
2, as shown in Figure 2: four metal bars that bent are in advance placed in front mould respective slot, again the screen cloth cutting is laid between two metal bars, make screen cloth corner just touch metal bar, guarantee that the cooled wind-guiding screen frame of screen cloth and injection moulding frame 16 is connected closely.
3, on the screen cloth laying, re-lay thin film.
4, start vacuum generator, apply a downward active force to film, make it be close to die surface together with screen cloth, avoided the folding of screen cloth.
5, the patrix that closes, links upper and lower mould fastening with bolt.
6, from patrix hot flow path, die cavity is carried out to injection moulding, open cooling water and carry out cooling to die cavity.
7, shift out patrix, take out product.
