Abstract
The utility model discloses a kind of double-colored car trim and its mould, its double-colored car trim includes the first moulding of different materials and the second moulding, is not merged in the faying face of same angle by two between first moulding and the second moulding.Its mould includes front cavity, rear cavity and sets the sealing knife of top glue plane and sidepiece glue plane, the sealing knife is located between the front cavity, rear cavity and moves up and down, and only has part glue plane to contact with the front cavity in the top glue plane of the sealing knife.The utility model is not due to being merged in 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, concaveconvex structure is adopted in faying face, can further improve this adhesion.
Description
Technical field
The utility model belongs to car trim, and in particular to a kind of double-colored car trim and its mould.
Background technology
For the double-colored product of edge formation, such as windshield decoration, often using sealing blade double-colored become
Type Mold Making.Due to very big 70-140MPA (700kgf/cm2), the traditional Double-color forming die of the pressure of resin during injection
In sealing knife using the non-bearing type of oil cylinder direct drive design, it is impossible to bear so big injection pressure, therefore first
During secondary injection, as shown in figure 1,5 top of sealing knife is all fitted with 3 glue plane of front cavity, only reserve by front cavity 3, rear cavity 4
The molding space 1 of the first resin is constituted with sealing knife 5, and sealing knife 5 is not subject to the injection pressure of stripping direction；Post forming
When, as shown in Fig. 2 sealing knife 5 moves back downwards the molding space 2 for reserving second resin.Processed by traditional Double-color forming die
Common double-colored bloom moulding, two kinds of resins can only merge in the thickness side of product cross section, the combination of bi-material
Power completely by post forming temperature fusion and chemical fusion, due to sectional area little（Usually 1-3MM is thick）Temperature exchange is poor, two
The adhesion for planting material is poor.
Utility model content
The purpose of this utility model is to provide a kind of good double-colored car trim of adhesive force between material and its shaping
Mould.
The technical scheme for realizing the employing of the utility model purpose is as follows：
The double-colored car trim that the utility model is provided, the first moulding including different materials and the second moulding,
Do not merged in the faying face of same angle by two between first moulding and the second moulding.
In the faying face, at least one faying face adopts concaveconvex structure.
The car trim is windshield decoration, and first moulding is windshield decoration
Body, second moulding for windshield decoration flexible glue, the upper plane of the flexible glue and the body it
Between adopt concaveconvex structure.
The mould of the double-colored car trim that the utility model is provided, including front cavity, rear cavity and sets top glue
Plane and the sealing knife of sidepiece glue plane, the sealing knife are located between the front cavity, rear cavity and move up and down, the envelope
Part glue plane is only had to contact with the front cavity in the top glue plane of glue knife；When the sealing knife is in top dead center position,
Structure between the glue plane not contacted with the front cavity in its sidepiece glue plane and top glue plane and the front cavity, rear cavity
Become the first molding space；In bottom dead center position, its top glue plane is molded sealing knife with the front cavity, rear cavity and first
The second molding space is constituted between space.
The glue plane not contacted with the front cavity in the top glue plane of the sealing knife is provided with concaveconvex structure.
Beneficial effect
The utility model is not due to by two in the combination of same angle between the first moulding and the second moulding
Face is merged, the adhesion of bi-material when can improve car trim double-shot moulding, using recessed in faying face
Male structure, can further improve this adhesion.The utility model can be applicable to the sealing of appearance requirement and become the double of knife technology
Color injection molding product.
The technical solution of the utility model is further illustrated below in conjunction with the accompanying drawings.

Specific embodiment
See Fig. 3 to Fig. 7, the mould of the double-colored car trim that the utility model is provided, including front cavity 3, rear mold
Benevolence 4 and set the sealing knife 5 of top glue plane 501,502 and sidepiece glue plane 503, the sealing knife 5 be located at the front cavity 3,
Between rear cavity 4, in the top glue plane of sealing knife 5, only part glue plane 501 is contacted with the front cavity 3；Sealing knife 5
Bottom is connected with sealing tool rest 6, and sealing tool rest 6 is connected with driving means, and driving means include T-shaped with what sealing tool rest 6 coordinated
The T groove of block 8 and T-shaped piece 8 cooperation is tiltedly carved 7 and tiltedly carves 7 oil cylinders 9 being connected with T groove, and this mould structure is the soft contact of pressure-bearing type
Sealing knife mold mechanism.During work, oil cylinder 9 drives T groove tiltedly to carve 7 and moves forward and backward, and drives sealing by T-shaped piece 8 and sealing tool rest 6
Knife 5 moves up and down.When the sealing knife 5 is in top dead center position, in its sidepiece glue plane 503 and top glue plane not with institute
State the glue plane 502 of the contact of front cavity 3 and between the front cavity 3, rear cavity 4, constitute the first molding space 1；Sealing knife 5 exists
During bottom dead center position, second is constituted between its top glue plane and the front cavity 3, rear cavity 4 and the first molding space 1 and is molded
Space 2；The glue plane 502 at 5 top of sealing knife is provided with concaveconvex structure.
Using the forming method of the double-colored car trim of the utility model mould making it is, the top of the sealing knife 5
