Abstract
The utility model discloses a mould for mfg, hard polyurethane foamed composite boards, which comprises a couple of hinge links, and the upper and lower molds arranged correspondingly. The utility model is simple in structure and low in fabrication cost. Curving arranged heat pipes ensure better foamed temperature of polyurethane, and high product quality of composite boards.
Description
Technical field
The utility model relates to a kind of mould of making the hard polyurethane foams composite plate.
Background technology
Be located at the hard polyurethane foams composite plate that the hard polyurethane foams between this two-layer fiber reinforced cement board is formed by two-layer fiber reinforced cement board and one deck, the advantage that can integrate above-mentioned two kinds of materials has light weight, intensity height, good heat insulating, water resistance advantages of higher.
But also there is not manufacturer production to appear above-mentioned hard polyurethane foams composite plate at present, its difficult point is: 600 * 600mm or 600 * 1200mm composite plate plate surface flatness Δ L are less than 1mm, and the flatness of composite plate sheet material depends on the flatness of making the composite plate mould.And the nucleation temperature of polyurethane foam the best in die cavity is about 50 degree, and the pressure during foaming is up to 3-5Kg/cm
2, therefore how to design high strength, take into account the economical mould of heating simultaneously again, become the technological difficulties of this project maximum.
Summary of the invention
The purpose of this utility model provides a kind of mould of making the hard polyurethane foams composite plate, and is simple in structure, cost is low, product quality is high.
The purpose of this utility model is achieved through the following technical solutions:
A kind of mould of making the hard polyurethane foams composite plate, it comprises, and a pair of hinge connects, corresponding patrix and the counterdie that is provided with.
Wherein, this patrix and this counterdie include framed, steel plate that is located at this framed inwall, one and are located at heating pipe on this steel plate, many and are located at the band iron on this steel plate and are located at this angle bar around framed.
Wherein, this heating pipe's bend alignment, these many band iron right-angled intersections connect, respectively on this band iron with this heating pipe's overlapping, have a semicircle orifice, allow this heating pipe pass.
Positive progressive effect of the present utility model is: it is made of patrix and the counterdie that hinge connects, correspondence is provided with, simple in structure, low cost of manufacture, the heating pipe of bend alignment guarantees polyurethane blowing temperature preferably, and the composite board product flatness is good, quality is high.
Description of drawings
Fig. 1 is the utility model preferred embodiment structural representation.
Fig. 2 is Figure 1A-A direction schematic diagram.
The specific embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
As shown in Figure 1 and Figure 2, a kind of mould of making the hard polyurethane foams composite plate, it comprises, and a pair of hinge connects, corresponding patrix and the counterdie that is provided with.
Patrix and counterdie include framed 1, steel plate that is located at framed 1 inwall 2, one and are located at heating pipe 3 on the steel plate 2, many and are located at the band iron 4 on the steel plate 2 and are located at angle bar 5 around framed 1.
Patrix is identical with the structure of counterdie, and each structure member electric welding connects, and framed 1 by making with the relatively poor material of the bonding property of polyurethane, and as metal, macromolecular material etc. are avoided forming bondingly with the polyurethane foam composite plate, influence the demoulding; It has certain pattern draft, and is conveniently stripped.Steel plate 2 guarantees the flatness of product.Heating pipe 3 is copper pipes, also can be other metal tube, and its bend alignment guarantees polyurethane blowing temperature preferably, and heating pipe's import and outlet are arranged on angle bar 5.Many band iron 4 equidistant right-angled intersections connect, and form a support, the pressure when being used to bear foaming in the die cavity.Heating pipe 3 and each root band iron 4 overlapping have semicircle orifice on the band iron 4, allow heating pipe 3 pass.Angle bar 5 is provided with around framed 1, protects framed.
During concrete the application, fiber reinforced cement board is cut into 600 * 600mm or 600 * 1200mm (also can polish cement plate, spray fluorine carbon or other coating then, enter next process behind the oven dry surface coating.)
The patrix of mentioning mould, open die cavity, respectively putting into a thickness on upper and lower mould is the 2-6mm fiber reinforced cement board, will prepare hard polyurethane foam combination material again and inject in the die cavity, patrix and the involutory envelope of counterdie is tight, through preheating, foaming (polyurethane foam pressure 3-5kg/cm
2), promptly get the hard polyurethane foams composite plate, deburring after maintenance a period of time, vanning after the cooling, the demoulding.
Be greatly improved and improve through the flatness (Δ L has reached 0.5mm) of the hard polyurethane foams composite plate of this Mould Machining and outward appearance, two kinds of materials of composite plate have globality, and promptly material interface can not peeled off, interfacial adhesion intensity height.
Claims (3)
1, a kind of mould of making the hard polyurethane foams composite plate is characterized in that, it comprises, and a pair of hinge connects, corresponding patrix and the counterdie that is provided with.
2, mould according to claim 1, it is characterized in that this patrix and this counterdie include framed, steel plate that is located at this framed inwall, one and be located at heating pipe on this steel plate, many and be located at the band iron on this steel plate and be located at this angle bar around framed.
3, mould according to claim 2 is characterized in that, this heating pipe's bend alignment, these many band iron right-angled intersections connect, respectively on this band iron with this heating pipe's overlapping, have a semicircle orifice, allow this heating pipe pass.
