Finished product die upper mold, puts into press by finished product die, under the ambient temperature of 20 degrees Celsius to 50 degrees Celsius, apply pressure be
35 kilograms to 40 kilograms/every square centimeter, pressing time be 50 seconds to 60 seconds solidification, then opening finished product die will be bonded with
The secondary finished product pad of EVA sheet takes out, and then edge-cutting and hole-punching completes described secondary finished product molding.
Scheme is further: described fiber material be model be the conjugate fiber material of ES4080 fiber and polyster fibre, combination
Ratio be 3 to 7, the temperature of described setting is 150 degrees Celsius to 180 degrees Celsius, the time of described setting be 100 seconds to 120
Second.
Scheme is further: described air-vent is evenly distributed on the upper and lower mould of die for blank, and upper and lower mould air-vent is handed over
Mistake is oppositely arranged.
Scheme is further: described vent diameter is 4mm to 8mm, and pitch-row is 20mm to 30mm.
Scheme is further: described die for blank is the aluminium sheet by 3mm to 6mm or the compressing mould of steel plate.
Scheme is further: described described fiber material is laid on corresponding region is to have the computer will the pattern number of input
According to the result by calculating, the laying carried out by the way of being accepted computer instruction by mechanical hand.
The invention has the beneficial effects as follows: directly raw material is put into mould be heating and curing according to same density, different-thickness
Molding, changes traditional moulding process, it is achieved that isodensity not equal thickness automobile internal partition sound heat insulating mattress；The advantage of this technique is also
Being, in the transition region that thickness does not waits, such as flex area, by the gap between mould, by mutually during thermosetting
Mobility be connected and accomplish isodensity and non-equal thickness so that it is sound-absorbing is consistent with heat insulation effect；I.e. simplify processing technique,
Save materials, improve again the concordance effect of sound-heat insulated cushion.
With embodiment, the present invention is described in detail below in conjunction with the accompanying drawings.
Accompanying drawing explanation
Fig. 1 is die for blank structural representation of the present invention.
Detailed description of the invention
A kind of isodensity not equal thickness automobile internal partition sound heat insulating mattress process, the sound-heat insulated cushion of molding is to have
The pad of different-thickness, described method includes a blank pad forming step and secondary finished product forming step, wherein:
A described blank pad forming step is: select a upper mold 2 with air-vent 1 as shown in Figure 1 and the hair of lower mold 3
Mold has, and calculates the fiber material with the different quality needed for isodensity different-thickness region according to the different-thickness region of pad, beats
Opening upper and lower mould, according to the different quality calculated, described fiber material is laid on corresponding region, close upper and lower mould, by blank
Baking oven sent into by mould, uses thermal cycle wind fiber material solidifying and setting hair described in hot melt by the way of air-vent heating die for blank
Base pad, takes out die for blank cooling after the time reaching a setting at a temperature of setting, and completes a blank pad and becomes
Type；
Described secondary finished product forming step is: select a finished product die with upper and lower mould, uses spray gun at the blank taken out
Padding a topcoating glue, open finished product die, by a piece of through baking oven for heating 180 degrees Celsius to 200 degrees Celsius, heat time heating time is 80 seconds
EVA sheet to baking in 100 seconds puts into finished product die bed die, and the thickness of EVA sheet is 2mm to 3mm；Then by blank pad coated face
On EVA sheet, finished product die upper mold of closing, finished product die is put into press, at 20 degrees Celsius to 50 degrees Celsius
Under ambient temperature, (preferably 25 degrees Celsius to 30 degrees Celsius), the pressure of applying are 35 kilograms to 40 kilograms/every square centimeter, add
The pressure time is solidification (preferably 60 seconds) in 50 seconds to 60 seconds, then opens finished product die and is taken by the secondary finished product pad being bonded with EVA sheet
Go out, then edge-cutting and hole-punching, complete described secondary finished product molding.
In embodiment: described fiber material be model be ES4080 low-melting fiber (softening temperature 110 DEG C, melting temperature 250
DEG C) and the conjugate fiber material of polyster fibre, the ratio of combination is 3 than 7(i.e.: low-melting fiber is 3, and polyster fibre is 7), described
Set temperature be 150 degrees Celsius to 180 degrees Celsius, be most preferably 160 degrees Celsius, the time of described setting be 100 seconds to 120
Second, it is most preferably 110 seconds.
In embodiment: described air-vent is evenly distributed on the upper and lower mould of die for blank, upper and lower mould air-vent is staggered relatively
