Abstract

The utility model discloses a forming die for curving plastic board, which can process great length plastic board. The utility model is characterized in that the utility model can heat different sites of the die, and the heating temperature is controlled by the utility model; the resilient deformation caused by the characteristics of the memory of the material and the different surface strain force on both sides of the die can be restrained when the great length plastic board is formed. The utility model has the advantages that the technology cycle of the utility model is short; the utility model can effectively guarantee the dimensional precision and the surface smoothness of products.

Description

Forming die for curving plastic board

The utility model relates to the mould of the big length plastic plate of a kind of bending machining.

Big length plastic material generally adopts expressing technique processing, but extrudes the section bar poor surface smoothness of processing, uncomfortable cooperation ornament materials.Therefore adopt the thermoplastic plastic plate then with mechanical force with its bending and molding method.Because most of thermoplastics have memory performance, after it was bent to desired shape, product must remain on the anchor clamps, until cooling, like this Jia Gong cycle longer, and still producing in use because the rebound deformation that the double-sided surface adaptability to changes causes.

The utility model provides a kind of big length plastic plate brake forming mould that can control temperature, this mould has temperature control device at sheet material processing negative camber and inboard, long limit, by at different time, control different parts method of temperature, utilize temperature to solve the lattice arrangement of deformation plance, change the adaptability to changes of double-sided surface, thereby suppress plastic plate rebound deformations owing to material memory characteristic and the different generations of double-sided surface adaptability to changes when bending forming.With the big length plastic plate goods of the utility model Mould Machining, can use as ornamental strong material such as senior balustrade, pelmet, door window frame.Process cycle is short, can effectively guarantee dimensional accuracy and surface smoothness.

Below in conjunction with accompanying drawing embodiment of the present utility model is described.Accompanying drawing is dark brown transparent pelmet bending machining schematic diagram.

Among the figure:

1,3 wooden pressing plates,

2,8 foldings,

4, processed plastic plate,

5,6,7 heating tubes,

9,10 fixtures,

11, workbench,

Bending machining example: at first will cut out good plastic plate insertion heating tube 7 and the interpolation slit between the anchor clamps 9, open heating tube 7, control temperature with pressure regulator, put down wooden pressing plate 3 behind the local softening, close heating tube 7 then, open heating tube 5, put down wooden pressing plate 1 behind the local softening, close heating tube 5, open heating tube 6 and keep certain hour, at last wooden pressing plate 1,3 is all opened, with the plastic plate taking-up of bending machining moulding.
