Description
Technical field
The present invention relates to car ceiling hot extrusion briquetting technique field, more particularly to a kind of car ceiling heat pressing and molding mold and
Its forming method.
Background technology
Car ceiling is the important component of vehicle interior trim, inner decorative ceiling and the attached type of metal plate roof, practicality in automobile
Had concurrently with dicoration, as in-car roof trim thing, luxurious sense and the comfort of increase automobile are not required nothing more than, with excellent
The performance such as fire-retardant, anti-soil and color fastness height, while also requiring the heat transfer outside reduction internal car noise and car, and enters to occupant's head
Row protection, the casing play at roof of the vehicle back plays an important role in terms of product physical and mechanical property is kept, inner decorative ceiling
Classification, processing technology etc. all have direct relation with casing play.
Car ceiling can be divided into surface layer and casing play from big configuration aspects, and surface layer and casing play pass through hot pressing or bonding
Mode be combined with each other, casing play is made up of thermoplasticity or thermosetting sheet material, for keeping the well-pressed of ceiling, is difficult ceiling
Deformation.
Due to car ceiling need according to roof structure mutually coincide, in addition it is also necessary to consider it is attractive in appearance in terms of factor, typically
For surface modeling, the processing method used at present is hot-press molding method, i.e. the composite split is put into baking oven heating
Hot-forming with hydraulic forming machine after to certain temperature, existing mould mostly uses steel mold, and steel mold passes through steel knot
Structure fixing of the forming frame is on heat pressing forming machines, and car ceiling needs to be retrofited according to customer demand in process at any time,
Steel mold cost is higher, and reconditioning and maintenance are relatively complicated, once changing product, steel mold will be eliminated therewith, in addition it is also necessary in addition
The mould of new construction is ordered, production cost is virtually improved, therefore, a kind of maintenance cost of exploitation design is low, is convenient for changing
Heat pressing and molding mold is this area urgent problem.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of car ceiling heat pressing and molding mold, viscous by using stacking
The high-density plate connect, by bonded and glass fiber cloth formation die face on the type face of die ontology, is entirely capable of as die ontology
