The specific embodiment
After state that the hot pressing principle mainly is that heat energy is passed to cut-parts via mould among the embodiment, make it typing, perhaps make two cut-parts weldings.Welding promptly utilizes energy that two or many materials are combined; Mode through the heat transmission lets face of weld reach its activation temperature; And utilize positive pressure to make face of weld after curing, produce mechanical bond power in the boundary zone; And the transmission of two face of weld Yin Gaowen makes the molecule absorption energy and produces intermolecular force, and then makes two cut-parts produce enough bond strengths.
In one embodiment of this invention, the generation of heat was to make electric energy convert heat energy into by the electric control system controls electrothermal tube during heat was transmitted.Electric-control system has automatically controlled interface, and it comprises the temperature setting, holds pressure time and various starting switch.
To shown in Figure 3, the set of molds of hot-pressing system comprises mold 10 and bed die 11 in one embodiment of the invention like Fig. 1, and the body of upper and lower mould is all cast by aluminium, and the overall size of upper and lower mould is looked concrete knapsack torn size and decided.
Mold 10 is mainly used in the transmission of heat energy; Mold is built-in with equally distributed many electrothermal tubes; And be connected with electric-control system, set the temperature that needs by the automatically controlled interface of electric-control system, projecture outside the positive slide fastener of knapsack, the clasp etc. in hot pressing; The central authorities of mold 10 become cavity 100, and edges has hollow out position 101.The bottom of mold 10 is the hot pressing circle 102 of an annular, and hollow out position 101 does not extend to hot pressing circle 102.Because in the conduction principle that heat is transmitted; Heat is passed to low-temperature region by high-temperature area, and high and quick for making heat transfer efficiency, the material of mold 10 has adopted the gradient type configuration; Adopt red copper at the mold that plays the direct heat pressure surface, instant heating trim ring 102 adopts red copper.Because the preferable metal material of thermal conductivity of red copper; And the requirement of temperature stabilization is very important in the hot pressing principle; Therefore adopt red copper in the mould contact surface of being responsible for hot pressing, the engagement edge of the hot pressing face of red copper mold is rounded, and lining produces heavier impression when pressure is scalded to avoid.
The body of bed die 11 also is to be cast by aluminum dipping form, and the upper surface 110 of bed die 11 is a plane, and upper surface 110 is its hot-pressed surface, and bed die 11 also has annular sidewall 111.Be provided with air channel 112 in the bed die 11, air channel 112 connects air draft system.Hot-pressed surface 110 outer rings of bed die 11 and the sidewall of bed die form equally distributed a plurality of wind inlet 114 respectively.Each wind inlet 114 connection air channel 112.By the air channel 112, wind inlet 114, the wind power energy of air draft system reaches absorption and is sleeved on the cut-parts on the bed die 11 and makes the accurately effect of location of cut-parts.
On the upper surface 110 of bed die 11, the position according to outer projectures such as the clasp of cut-parts, slide fasteners forms hollow out 115 respectively, and when scalding to avoid pressing, outer projecture is damaged.Because position, cut-parts top is multilayer cut-parts stack, the thickness of stack place goes out much than remainder thickness is good thick, presses when boiling hot in order to make; The driving fit fully of upper and lower mould, at the thicker position of corresponding cut-parts, bed die 11 is recessed to form groove 116 downwards; Groove 116 is built-in with hard gel sheet or silica gel strip 117 (as shown in Figure 9); The space that utilizes groove to abdicate, and by the pliability of silica gel sheet, let and press the process of scalding to be unlikely to because of the incomplete situation of the excessive generation welding of high low head.
In one embodiment of this invention, mold 10 is to be driven by a baric systerm, and baric systerm is responsible for supply pressure in hot pressing, and sufficient source of the gas air pressure makes the stability of heat pressing process promote significantly.
Fig. 1 is to be placed on the work board to set of molds shown in Figure 3, and the pedestal of work board is stable, and is positioned over flat bottom surface, and whole hot-forming system is placed on drying and the good place of scavenging performance can be provided.
For air draft system, the concrete structure of baric systerm and electric-control system has not just been spoken more, and it can adopt the commercially available prod structure to form in an embodiment of the present invention.Hot press forming technology is described to embodiment shown in Figure 3 below in conjunction with Fig. 1.
In one embodiment of this invention, shown in figure 11, the hot press forming technology of knapsack comprises step 301, step 302 and step 303.
As shown in Figure 4; Mode of operation is enclosed within on the bed die 11 after 40 inside and outside of outer ring cut-parts are reverse in step 301; The position line of cut-parts 40 edge aligned on bed die 11; By hand the top edge of cut-parts 40 is pressed to the upper surface 110 of bed die 11, and utilize air draft system to adsorb cut-parts 40, make cut-parts 40 docile on bed die 11 by means of wind inlet 114.
As shown in Figure 5, hot pressing is directly carried out in the outer ring cut-parts 40 that utilize mold 10 will be positioned on the bed die 11, just can accomplish the typing of bound edge 401.
As shown in Figure 7, obtain the knapsack cut-parts 60 (front that has shown cut-parts among the figure is compared with shown in Figure 6, and interior outside is reverse) of welding moulding at last.
On step 303, the facing up of knapsack cut-parts 60, heat insulating board on the pad just can be accomplished and guarantee the seamless heat seal strength and the overall appearance of knapsack body after hot pressing once more.
As shown in Figure 8, in another embodiment of the present invention, when outer ring cut-parts 40 are positioned; To thicker or relative harder lining, can there be bigger gap in the hot-pressed surface of cut-parts edge and bed die, therefore is difficult to be adjacent to by air draft system fully be positioned at bed die; After air draft system is opened; Tiling a slice heatproof transparent PET sheet 70 in cut-parts 40 again, PET sheet 70 not only can make air draft system because of absorption PET takes advantage of a situation cut-parts overlayed on mould, more can avoid lining to scald variable color or impaired because of high-temperature high-pressure; And clear PET sheet 70 also is convenient to observe in position fixing process, and whether the fold of adjustment of the position of the back gauge of cut-parts and corner produces.
As shown in Figure 9; In another embodiment of the present invention, in step 301 and/or 302, be placed with woven wire 90 on the bed die 11; The 80 purpose web frames that woven wire 90 for example is made up of stainless (steel) wire and copper mesh; The wind power energy of air draft system directly reaches absorption cut-parts 40, accurately locatees the purpose of cut-parts through woven wire 90 like this, again because the areola density of woven wire 90 is high, can not produce the hole vestige because of pressure make lining; And adopt two kinds of unlike material silk screens to form; The then hardness substrate of stainless (steel) wire capable of using and coat it by copper mesh outer to make it receive limit more smooth-going, and the thermal conductivity of copper material also can make the heat conduction transmission of fusion process more complete.
