Description
Technical field
This utility model belongs to the exterior panel of windshield, is specifically related to a kind of trichroism external decoration of windshield
Bar and mould thereof.
Background technology
The exterior panel of windshield typically uses the trichroism high light ornamental strip that band positive and negative seals.Traditional trichroism height
Light ornamental strip, as in figure 2 it is shown, add man-hour requirement injection mo(u)lding body 2, flexible glue 3,4 respectively, then by spraying on body 2
Obtain the surface 10 of Gao Guang, then two flexible glues 3,4 double faced adhesive tape or glue are bonded on body 2, its complex technical process, conjunction
The poor reliability that lattice rate is low, cost is high and flexible glue is bonding.If applying trichroism injection mo(u)lding, need trichroism injection-moulding device and three
Color injection mold, equipment investment and die cost are the highest.Owing to trichroism injection mold necessarily uses shifting formwork or the mode loosed core
Realize the conversion of three die cavities, more to profile and the structure restriction ratio of trichroism product, conplane body 2 He can only be realized
The trichroism molding of flexible glue 3,4 of body about 2, as shown in Figure 1, it is impossible to the ornamental strip of realization trichroism one as shown in Figure 2 is simultaneously
The trichroism molding that left and right is upper and lower.
Utility model content
The purpose of this utility model is that providing one to be suitable for common injection-moulding device produces, and quality is good, the automobile of low cost
The trichroism exterior panel of windshield and mould thereof and method.
The technical scheme realizing the employing of this utility model purpose is as follows:
The trichroism exterior panel of windshield that this utility model provides, including ABS skeleton, PMMA(acrylic) Gao Guang
Top layer, TPU(Polyurethane Thermoplastic Elastomer) soft-sided, described PMMA height light top layer and TPU soft-sided are each provided at described ABS skeleton
On, described ABS skeleton 2 is provided with the injection channel connected with described TPU front soft-sided 3 and TPU reverse side soft-sided 4.
Described PMMA height light top layer is located at the above of described ABS skeleton and has a bound edge, and described TPU soft-sided is divided into TPU just
Thin-skinned limit 3 and TPU reverse side soft-sided 4, they are respectively provided at below side and the bound edge on described PMMA height light top layer.
The mould of the trichroism exterior panel of above-mentioned windshield that this utility model provides, is two color injection moulds
Tool, including the front cavity cooperated and rear cavity, be positioned at front cavity, the slide block of rear cavity both sides, being positioned at slide block can be in the past
The inside sealing cutter that rear slip coordinates with described front cavity and rear cavity.
Beneficial effect
1, this utility model product substantially increases the exterior quality of product under equivalent constructions, improves the environmental protection of product
Grade, reduce product cost, decrease product weight.
2, body skeleton is placed in bicolor injection mould by this utility model mould as inserts, available trichroism
(three kinds of materials: ABS body skeleton, PMMA height trimmed book surface layer, the one-body molded product of TPU soft-sided) high light product, and by sliding
Block adds sealing cutter and realizes the technological break-through that positive and negative is encapsulated, preferably solves above-mentioned the asking of existing trichroism injection mold existence
Topic.
3, this utility model method uses dual-color forming to add insert-moulding technique, has both met effect of trichroism molding, has dashed forward again
Break the limitation of trichroism injection forming mold, it is achieved the left right-alternative fusion structure of lamination up and down.
This utility model has extraordinary practical value and boundless market prospect.
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings.

Detailed description of the invention
Seeing Fig. 3, Fig. 4, the trichroism exterior panel of windshield of the present utility model, including ABS skeleton 2, PMMA Gao Guang
Top layer 1, TPU front soft-sided 3 and TPU reverse side soft-sided 4, described PMMA height light top layer, TPU front soft-sided 3 and TPU reverse side soft-sided 4
Being each provided on described ABS skeleton 2, described ABS skeleton 2 is provided with and connects with described TPU front soft-sided 3 and TPU reverse side soft-sided 4
Injection channel 9；Described PMMA height light top layer 1 is located at the above of described ABS skeleton 2 and has a bound edge, described TPU front soft-sided 3
It is respectively provided at below side and the bound edge on described PMMA height light top layer 1 with TPU reverse side soft-sided 4.
The moulding injection mold of the trichroism exterior panel of the above-mentioned windshield of this utility model, as it is shown in figure 5, be two colors
Injection mold, including the front cavity 5 cooperated and rear cavity 6, is positioned at front cavity 5, the slide block 8 of rear cavity 6 both sides, is positioned at cunning
The inside sealing cutter 7 that can coordinate with described front cavity 5 and rear cavity 6 with slide anteroposterior in block 8.
The forming method of the trichroism exterior panel of the above-mentioned windshield of this utility model, uses described mould, presses
Following steps are carried out:
Step one, first molding ABS skeleton 2 in monochromatic mould；
Step 2, see Fig. 5, Fig. 6, described ABS skeleton 2 inserted the die cavity of described mould, then front cavity 5, after
Die 6 matched moulds, slide block 8 is motionless, by ABS skeleton 2 be collectively forming with rear cavity 6 TPU reverse side soft-sided 4 molding space 4 ' and with become
The injection channel 9 of type space 4 ' connection, internal sealing cutter 7 reach laminating front cavity 5, with front cavity 5, rear cavity 6 and ABS skeleton
2 molding spaces 1 ' being collectively forming PMMA height light top layer 1, by carrying out being molded formation PMMA Gao Guang for the first time to molding space 1 '
Top layer 1, as shown in Figure 7；
Step 3, seeing Fig. 8, behind molding PMMA height light top layer 1, slide block 8 is motionless, and internal sealing cutter 7 retreats a certain distance
After, with the molding space 3 ' that front cavity 5, PMMA height light top layer 1, ABS skeleton 2 and slide block 8 are collectively forming TPU front soft-sided 3, lead to
Cross the described injection channel 9 in ABS skeleton 2 and connect described molding space 3 ' and molding space 4 ', then from molding space 3 ' side
Carry out second time to be molded, form TPU front soft-sided 3 and TPU reverse side soft-sided 4 by second time injection, as shown in Figure 9.
By the trichroism exterior decoration strip product of this utility model windshield of said method injection mo(u)lding such as Fig. 3, Fig. 4 institute
Showing, ABS skeleton 2 is provided with a plurality of injection channel 9, TPU front soft-sided 3 and TPU reverse side soft-sided 4 is linked together.
In said method, due to TPU front soft-sided 3 and TPU reverse side soft-sided 4 by the injection channel 9 on ABS skeleton 2 even
It is connected together, can be with single injection-molded；And avoid and on mould, open passage to connect TPU front soft-sided 3 and TPU reverse side soft
Limit 4 and the other problems that causes.
