Abstract
The invention discloses a kind of double-colored car trim and mould thereof and method, its double-colored car trim includes the first moulding and second moulding of different materials, is not merged at the faying face of same angle by two between described first moulding and the second moulding.Its mould includes front cavity, rear cavity and sets top glue plane and the sealing cutter of sidepiece glue plane, described sealing cutter is located between described front cavity, rear cavity and moves up and down, and in the top glue plane of described sealing cutter, only part glue plane contacts with described front cavity.Due to the fact that and do not merged at the faying face of same angle by two between the first moulding and the second moulding, the adhesion of bi-material when can improve car trim double-shot moulding, in faying face, use concaveconvex structure, can further improve this adhesion.The sealing that present invention can apply to appearance requirement becomes the double-shot moulding product of cutter technology.
Description
Technical field
The invention belongs to car trim, be specifically related to a kind of double-colored car trim and mould thereof and method.
Technical background
For the double-colored product of edge formation, such as windshield decoration, often use the double-colored one-tenth of sealing blade
Mould makes.Due to the biggest 70-140MPA of the pressure (700kgf/cm2) of resin, traditional Double-color forming die during injection
In sealing cutter use the design of non-bearing type that oil cylinder directly drives, it is impossible to bear the biggest injection pressure, therefore first
During secondary injection, as it is shown in figure 1, all fit with front cavity 3 glue plane in sealing cutter 5 top, only reserve by front cavity 3, rear cavity 4
With the molding space 1 that sealing cutter 5 constitutes the first resin, sealing cutter 5 is not subject to the injection pressure of stripping direction；Post forming
Time, as in figure 2 it is shown, sealing cutter 5 moves back downwards the molding space 2 reserving the second resin.Processed by tradition Double-color forming die
Common double-colored high light moulding, two kinds of resins can only merge in the thickness side of product cross section, the combination of bi-material
Power completely by the temperature fusion of post forming and chemical fusion, owing to sectional area little (usually 1-3MM thick) temperature exchange is poor, two
The adhesion planting material is poor.
Summary of the invention
It is an object of the invention to provide the good double-colored car trim of adhesive force between a kind of material and mould thereof
And method.
The technical scheme realizing the object of the invention employing is as follows:
The double-colored car trim that the present invention provides, including the first moulding and second moulding of different materials, described first
Do not merged at the faying face of same angle by two between moulding and the second moulding.
In described faying face, at least a faying face uses concaveconvex structure.
Described car trim is windshield decoration, and described first moulding is windshield decoration
Body, described second moulding is the flexible glue of windshield decoration, the upper plane of described flexible glue and described body it
Between use concaveconvex structure.
The mould of double-colored car trim that the present invention provides, including front cavity, rear cavity with set top glue plane
With the sealing cutter of sidepiece glue plane, described sealing cutter is located between described front cavity, rear cavity and moves up and down, described sealing cutter
Top glue plane in only part glue plane contact with described front cavity；When described sealing cutter is at top dead center position, its side
The is constituted between the glue plane and described front cavity, the rear cavity that do not contact with described front cavity in portion's glue plane and top glue plane
One molding space；Sealing cutter when bottom dead center position, its top glue plane and described front cavity, rear cavity and the first molding space
Between constitute the second molding space.
The glue plane not contacted with described front cavity in the top glue plane of described sealing cutter is provided with concaveconvex structure.
The forming method of the double-colored car trim that the present invention provides, including using described mould, when described sealing cutter exists
During top dead center position, its sidepiece glue plane and the glue plane not contacted with described front cavity in the glue plane of top and described front mould
Constitute the first molding space between core, rear cavity, form the first moulding by injection for the first time；Sealing cutter is at bottom dead center position
Time, constitute the second molding space between its top glue plane and described front cavity, rear cavity and the first moulding, by second time
Injection forms the second moulding.
The glue plane not contacted with described front cavity in the top glue plane of described sealing cutter is provided with concaveconvex structure, when
When being once molded, described first moulding structure forms corresponding described concaveconvex structure, when second time injection, described second note
The faying face of concaveconvex structure is formed between plastic and described first moulding.
Beneficial effect
Due to the fact that and do not melted at the faying face of same angle by two between the first moulding and the second moulding
Close, the adhesion of bi-material when can improve car trim double-shot moulding, faying face uses concaveconvex structure, can
Improve this adhesion further.The sealing that present invention can apply to appearance requirement becomes the double-shot moulding of cutter technology to produce
Product.
Further illustrate technical scheme below in conjunction with the accompanying drawings.
