Description
Technical field
The invention belongs to car trims, and in particular to a kind of double-colored car trim and its molding die and method.
Technical background
For the double-colored product of edge formation, such as windshield decoration, often using sealing blade it is double-colored at
Type Mold Making.The very big 70-140MPA (700kgf/cm2) of pressure of resin, traditional Double-color forming die when due to injection molding
In the design of non-bearing type that is directly driven using oil cylinder of sealing knife, so big injection pressure cannot be born, therefore first
When secondary injection molding, as shown in Figure 1,5 top of sealing knife is all bonded 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, 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 of resin.It is 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 two kinds of materials
Power lean on completely the temperature of post forming fuse and chemical fusion, due to small (the usually 1-3MM thick) temperature exchange of sectional area is poor, two
The binding force of kind material is poor.
Summary of the invention
The purpose of the present invention is to provide adhesive force between a kind of material good double-colored car trims and its molding die
And method.
Realize the object of the invention the technical solution adopted is as follows:
Double-colored car trim provided by the invention, the first moulding and the second moulding including different materials are described
It is not merged in the faying face of same angle between first moulding and the second moulding by two.
At least one faying face uses concaveconvex structure in the faying face.
The car trim is windshield decoration, and first moulding is windshield decoration
Ontology, second moulding is the flexible glue of windshield decoration, the upper plane of the flexible glue and the ontology it
Between use concaveconvex structure.
The molding die of double-colored car trim provided by the invention, including front cavity, rear cavity and set top glue plane
With the sealing knife of side glue plane, the sealing knife is located between the front cavity, rear cavity and moves up and down, the sealing knife
Top glue plane in only part glue plane contacted with the front cavity；When the sealing knife is in top dead center position, side
Is constituted in portion's glue plane and top glue plane between the glue plane not contacted with the front cavity and the front cavity, rear cavity
One molding space；Sealing knife is in bottom dead center position, top glue plane and the front cavity, rear cavity and the first molding space
Between constitute the second molding space.
The glue plane not contacted with the front cavity in the top glue plane of the sealing knife is equipped with concaveconvex structure.
The forming method of double-colored car trim provided by the invention, including the mold is used, when the sealing knife exists
When top dead center position, the glue plane and the preceding mould that are not contacted with the front cavity in side glue plane and top glue plane
The first molding space is constituted between benevolence, rear cavity, is molded by first time and is formed the first moulding；Sealing knife is in bottom dead center position
When, the second molding space is constituted between top glue plane and the front cavity, rear cavity and the first moulding, is passed through second
Injection molding forms the second moulding.
The glue plane not contacted with the front cavity in the top glue plane of the sealing knife is equipped with concaveconvex structure, when the
The corresponding concaveconvex structure, when being molded for second, second note are formed when primary injection molding, on the first moulding structure
The faying face of concaveconvex structure is formed between plastic and first moulding.
Beneficial effect
The present invention due between the first moulding and the second moulding pass through two not the faying face of same angle into
Row fusion, the binding force of two kinds of materials when car trim double-shot moulding can be improved, using concave-convex knot in faying face
Structure can further improve this binding force.Present invention can apply to have the sealing of appearance requirement at knife technology double-shot moulding at
Type product.
Technical solution of the present invention is further illustrated with reference to the accompanying drawing.

Specific embodiment
See Fig. 3 to Fig. 7, the molding die of double-colored car trim provided by the invention, including front cavity 3,4 and of rear cavity
If the sealing knife 5 of top glue plane 501,502 and side glue plane 503, the sealing knife 5 is located at the front cavity 3, rear cavity
Between 4, only have part glue plane 501 to contact with the front cavity 3 in the top glue plane of sealing knife 5；The lower part of sealing knife 5 with
Sealing tool apron 6 connects, and sealing tool apron 6 is connect with driving device, and driving device includes the T-block 8 cooperated with sealing tool apron 6 and T
The T slot that type block 8 cooperates tiltedly carves 7 and tiltedly carves the oil cylinder 9 of 7 connections with T slot, and this mould structure is the soft contact sealing knife of pressure-bearing type
Mold mechanism.When work, oil cylinder 9 drives T slot tiltedly to carve 7 and moves forward and backward, and drives sealing knife 5 to do by T-block 8 and sealing tool apron 6
