Abstract
The utility model discloses a forming mold for producing an aerogel vacuum heat-insulating plate, which comprises a forming barrel and a seal cover matched with the mouth of the forming barrel, wherein a porous sleeve is arranged in the forming barrel for dividing the interior of the forming barrel into a vacuum adsorption fixing cavity and a vacuum forming cavity nested with each other. The aerogel vacuum heat-insulating plate produced by the forming module has the advantages of regular shape, controllable size, no shrinkage, low thermal conductivity and better heat insulation effect.
Description
Technical field
The utility model relates to a kind of shaping die, is specifically related to a kind of shaping die of producing the aerogel vacuum heat-insulating plate.
Background technique
Vacuum heat-insulating plate (VIP) is a kind of thermal insulating material of superadiabatic, and the application area of VIP is more extensive, has been applied to fields such as refrigerator, freezer, Refrigerated container, medical HEATING BOX.VIP adopts the vacuum insulation principle, and promptly under lower air pressure, it is very little that the thermal conductivity of material can become, and in addition, selects comparatively desirable sandwich layer thermoinsulation material.Can reach comparatively desirable insulation effect.
Existing vacuum heat-insulating plate has two kinds of structures usually, one for being provided with adiabatic core in stacked bag, with the vacuum pumping of stacked bag, and in stacked bag, adsorbent is set, improve degree of vacuum in the stacked bag, can significantly reduce the thickness of heat insulation layer under the above-mentioned thermal shield situation identical, still with original antivacuum heat insulating effect, because the core in the stacked bag has higher thermal conductivity equally, insulation effect is relatively poor under the higher environment of temperature.For addressing the above problem, someone proposes and has invented the lower thermoinsulation material of a kind of thermal conductivity, aerosil, this aerogel is the porous silica structure, as Chinese patent 96192192 disclosed structures, and the narrow and small complications in slit between structure, inlet air flow path is long, thermal conductivity further reduces with respect to original thermoinsulation material, and with the core body of aerosil as vacuum heat-insulating plate, the effect of thermal shield further improves.
Yet, because aerosil moulding difficulty relatively, existing utilize aerosil to be generally with the other materials compound molding or framework material be set as core material of vacuum heat insulation plate.Thereby influenced the thermal conductivity of aerogel, made the performance of aerogel vacuum heat-insulating plate not bring into play fully.
At present, because aerogel has bigger contractibility in vacuum, therefore directly aerogel being packaged in preparation vacuum heat-insulating plate in the vacuum bag also not have the manufacturing mechanism of being correlated with.
Summary of the invention
The utility model provides a kind of shaping die that vacuum bag is produced the aerogel vacuum heat-insulating plate that is used for directly aerogel being packaged in.
A kind of shaping die of producing the aerogel vacuum heat-insulating plate comprises moulding bucket and the sealing cover that matches with moulding bucket bung, and described inside is provided with porous sleeve, and porous sleeve is divided into mutually nested vacuum suction lock chamber and vacuum forming chamber with moulding bucket inside.
The some apertures of distribution on the described porous sleeve, the diameter 0.05～10mm of aperture.
Described porous sleeve) shape is similar to the moulding bucket, and the porous sleeve volume inside is the vacuum forming chamber, is the vacuum suction lock chamber between porous sleeve and the moulding bucket, communicates by the some apertures on the porous sleeve between vacuum forming chamber and vacuum suction lock chamber.Externally in the encapsulation bag when make using vacuumize the identical air pressure of maintenances in the encapsulation process and prevent the contraction of encapsulation bag.
The barrel of described moulding bucket is provided with vacuum orifice.
Be provided with seal ring between described moulding bucket and the sealing cover, be used for preventing the gas leakage of vacuum moulding bucket vacuum forming chamber.
Described sealing cover is provided with vacuum tap, material inlet and packaging by hot pressing bar.
Described vacuum tap, material inlet are arranged side by side, and length requirement can stretch into the open top in vacuum forming chamber, and the open top in vacuum forming chamber is convenient to the work of packaging by hot pressing bar for falling wedge shape.
The length that described packaging by hot pressing bar stretches into the mouth of falling the wedge shape place in vacuum forming chamber should surpass the length that vacuum tap and material inlet stretch into the mouth of falling the wedge shape place in vacuum forming chamber.
Utilize the prepared aerogel vacuum heat-insulating plate of the utility model shaping die profile rule, controllable size, no shrinkage phenomenon, thermal conductivity is low, and the insulation insulation effect is better.

Embodiment
Referring to, the utility model shaping die comprises moulding bucket 1 and the sealing cover 2 that matches with moulding bucket 1 bung, moulding bucket 1 inside is divided into mutually nested vacuum suction lock chamber 3 and vacuum forming chamber 4 by porous sleeve 20.
The some apertures of distribution on the porous sleeve 20, the diameter 0.05～10mm of aperture.
The barrel of moulding bucket 1 is provided with vacuum orifice 5.
Be provided with seal ring 6 between moulding bucket 1 and the sealing cover 2, be used for preventing the gas leakage of vacuum moulding bucket vacuum forming chamber.
Vacuum tap 7, material inlet 8 are arranged side by side, and length requirement can stretch into the open top in vacuum forming chamber 4, and the open top in vacuum forming chamber 4 is convenient to 9 work of packaging by hot pressing bar for falling wedge shape.
The length that packaging by hot pressing bar 9 stretches into the mouth of falling the wedge shape place in vacuum forming chamber should surpass the length that vacuum tap 7 and material inlet 8 stretch into the mouth of falling the wedge shape place in vacuum forming chamber.
During work, at first will encapsulate bag 10 put into the vacuum forming chambeies 4 of moulding bucket 1 and evenly cover with the chamber wall on, aerogel 11 is packed in the encapsulation bag, the aerogel height is no more than wedge shape mouth low side.Then sealing cover 2 is placed on the moulding bucket 1, and makes packaging by hot pressing bar 9 be positioned at encapsulation bag 10 both sides, make vacuum tap 7 and material inlet 8 in encapsulation bag 10.Build the back and by the bleeding point on the moulding bucket 15 vacuum suction lock chamber 3 is evacuated, make the Filling bag adsorbed close on the inwall in vacuum forming chamber 4, by vacuumizing in 7 pairs of Filling bags of vacuum tap, this moment, material inlet 8 should be closed behind the certain hour.After reaching the certain vacuum degree in the encapsulation bag 10, close vacuum tap 7 and open material inlet 8 and give in the encapsulation bag 10 reinforcedly, and then close material inlet 8 and open vacuum tap 7 and vacuumize, make for several times that so repeatedly encapsulation bags 10 is filled till.After encapsulation bag 10 is filled, close vacuum tap 7 and encapsulate by 9 pairs of encapsulation bags 10 of packaging by hot pressing bar simultaneously.Allow the bleeding point 5 on the moulding bucket 1 connect atmosphere then, moulding bucket 1 is separated with sealing cover 2 and encapsulation bag 10, and the taking-up Filling bag, product promptly got.
