Description of drawings
Accompanying drawing is a kind of structural representation of nanometer hot padding device of the present invention.
Among the figure, 1 top board, 2 cylinders, 3 cavitys, 4 spout holes, 5 air intake ducts, 6 films, 7 O-ring seals, 8 heat insulating mattress, 9 bases, 10 exhaust ducts, 11 vacuum chambers, 12 pressure chambers, 13 uviol lamps, 14 heating plates, 15 blanks, 16 moulds.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done further explain.
Shown in accompanying drawing, nanometer hot padding device of the present invention comprises mould 16, blank 15, heating plate 14, base 9, cavity 3, and heating plate 14 is placed on the base 9; Blank 15 is placed on the heating plate 14, and mould 16 is placed on the blank 15, and cavity 3 forms confined space with base 9 movable sealings; Mould 16, blank 15 and heating plate 14 are enclosed in this confined space; Also be provided with film 6 in the said cavity 3, this film 6 is fixed at the sealing contact surface place of said cavity 3 with base 9, and the confined space that cavity and base are constituted is divided into pressure chamber 12 and vacuum chamber 11; Pressure chamber 12 communicates with air intake duct 5, and vacuum chamber 11 communicates with exhaust duct 10.
Hot padding comprises the steps,
Step 1: earlier mould 16 is overlayed on the heating plate 14 with blank 15 (blank of hot padding is generally plastics) mutually, spread film 6, cavity 3 presses down in the groove with film 6 embedding bases 9 and compresses, and film 6 is divided into pressure chamber 12 and vacuum chamber 11 with cavity 3;
Step 2: vacuum chamber 11 is vacuumized through exhaust duct 10;
