The device comprises a lower template and an upper template which can movably cover on the lower template; a forming cavity is formed on one lateral side of the lower template facing to the upper template; a feed channel used for injecting foam particles into the forming cavity of the lower template is arranged in the upper template, and a steam conveying pipe and a cooling water conveying pipe used for respectively sending the outside steam and cooling water into the forming cavity of the lower template are further arranged in the upper template; one end of the steam conveying pipe is communicated with the forming cavity; a vacuum pipe is arranged in the lower template; one end of the vacuum pipe is communicated with the forming cavity; and the other end of the vacuum pipe is connected with a vacuum extraction device. The device provided by the utility model has the beneficial effects that the pressure in the forming cavity and the pressure in block-shaped materials are the same as the external atmospheric pressure during opening the mould, and no pressure difference exists, so the block-shaped materials are hard to deform, the quality of formed products is ensured; and moreover, the consumption of steam is greatly reduced and the production cost is reduced.
Description
Technical field
The utility model relates to a kind of shaped device, particularly a kind of foam-formed device that is used to make foamed product.
Background technology
Existing foam-formed mould; Its structure comprises lower bolster and the movable cope match-plate pattern that is covered on this lower bolster; Be provided with the moulding chamber in this lower bolster, be provided with the indoor pan feeding passage of forming cavity that foam beads is injected this lower bolster in this cope match-plate pattern, and extraneous steam and cooling water are fed through the indoor steam pipeline and the cooling water carrier pipe of forming cavity of this lower bolster; One end of this steam pipeline communicates with the moulding chamber; The other end of this steam pipeline stretches out outside the cope match-plate pattern, and an end of this cooling water carrier pipe communicates with the moulding chamber, and the other end of this cooling water carrier pipe stretches out outside the cope match-plate pattern.During use, first material feeding can be with in the foam beads injection moulding chamber through the pan feeding passage during material feeding; Soften, solidify, pass through steam pipeline when softening with in the extraneous steam injection moulding chamber, each indoor foam beads of forming cavity receives thermal softening and is set in together, forms a block, and the indoor temperature of forming cavity this moment is 120 ℃; Finally demould; It is indoor earlier through the cooling water carrier pipe water in the external world to be delivered to forming cavity during the demoulding; The indoor temperature of forming cavity is further reduced, when the indoor temperature of forming cavity and block reach below 40 ℃, stop to carry cooling water, open upper module again to the cooling water carrier pipe; Block demoulding from the moulding chamber of cooling is come out, form the moulding article.
Yet the foam-formed device of this kind structure during die sinking, usually exists pressure differential to cause block to deform because of the indoor pressure of forming cavity and the pressure in the block and ambient atmosphere, thereby causes the quality of moulding article comparatively unstable; Simultaneously; Because after the demoulding of moulding article; The indoor temperature of forming cavity is lowered by to below 40 ℃; Then the mould steam that all need add more amount after every completion once-through operation and when carrying out next operation just can make the indoor temperature of forming cavity reach 120 ℃, makes the consumption of steam more like this, increases production cost.
In view of this, the inventor furthers investigate the structure of foam-formed device, is then produced by this case.
The utility model content
But the purpose of the utility model provides a kind of foam-formed device of the high temperature demoulding, makes block not yielding during its die sinking, makes the quality of moulding article comparatively stable, and can reduce steam consumption, reduces production costs.
The technical scheme of the utility model is such: but a kind of foam-formed device of the high temperature demoulding; Comprise lower bolster and the movable cope match-plate pattern that is covered on this lower bolster; This lower bolster offers the moulding chamber on a side of this cope match-plate pattern; Be provided with the indoor pan feeding passage of forming cavity that foam beads is injected this lower bolster in this cope match-plate pattern; And extraneous steam and cooling water be fed through the indoor steam pipeline and the cooling water carrier pipe of forming cavity of this lower bolster respectively, and an end of this steam pipeline communicates with the moulding chamber, and the other end of this steam pipeline stretches out outside the cope match-plate pattern; One end of this cooling water carrier pipe communicates with the moulding chamber, and the other end of this cooling water carrier pipe stretches out outside the cope match-plate pattern; Be provided with vacuum tube in the above-mentioned lower bolster, an end of above-mentioned vacuum tube communicates with above-mentioned moulding chamber, and the other end of above-mentioned vacuum tube is connected with vaccum-pumping equipment.
Above-mentioned vaccum-pumping equipment is a vacuum pumping pump.
Above-mentioned vacuum tube is erected in the above-mentioned lower bolster, and the lower end of above-mentioned vacuum tube communicates with above-mentioned moulding chamber, and the upper end of above-mentioned vacuum tube extends to outside the upper surface of above-mentioned lower bolster.
After adopting such scheme, but the foam-formed device of a kind of high temperature demoulding of the utility model, owing to be provided with vacuum tube in the lower bolster; Above-mentioned and end vacuum tube communicates with the moulding chamber, and the other end of vacuum tube is connected with vaccum-pumping equipment, like this; It is indoor when the demoulding, earlier through the cooling water carrier pipe water in the external world to be delivered to forming cavity, and the block indoor to forming cavity cools off, and when the indoor temperature of forming cavity and block reach the 80-90 ℃ of left and right sides, stops to carry cooling water to the cooling water carrier pipe; Open vaccum-pumping equipment again, and the moulding chamber is carried out vacuum pumping, at this moment through vacuum tube; Because the forming cavity sky is vacuum state, and the indoor water temperature of forming cavity is prone to cause water temperature to reach boiling temperature once more at 80-90 ℃ like this; The boiling once more of water can make block that distending slightly takes place, and promptly the air that comprises in can be simultaneously to block when the moulding chamber is vacuumized of vacuum equipment vacuumizes, and makes not have pressure differential between moulding chamber and block; When the indoor pressure of forming cavity and the pressure in the block all can be consistent with the pressure of external atmosphere pressure fully, can close vaccum-pumping equipment, and open upper module, block demoulding from the moulding chamber is come out; Like this; Block does not have the problem that has pressure differential when die sinking, make block not yielding, thereby has guaranteed the quality of moulding article; After the demoulding of the article of moulding simultaneously; The indoor temperature of forming cavity is about 80-90 ℃; Then mould all only needs to add more a spot of steam and can make the indoor temperature of forming cavity reach 120 ℃ after every completion once-through operation and when carrying out next operation; Greatly reduce the consumption of steam, thereby reduced production cost.
