Abstract
The utility model relates to a large pulp-mould which comprises an upper body 1, a lower body 2 which is matched with the upper body 1, and an exhaust and drainage device 3 which is positioned under the lower body 2 and is connected with a vacuum pump, wherein, the upper body 1 is provided with a heating device 4 inside, and the lower body 2 is provided with a material chamber 5 inside. The bottom of the material chamber is provided with a via hole 6. The utility model can complete the molding and the shaping procedures of pulp-mould products in one step.
Description
Technical field:
The utility model relates to a kind of paper pulp mould production mould, the large-scale paper pulp mould of especially a kind of production mould.
Background technology:
At present, pulp molding technology is essentially following two kinds of forms: a kind of is by the transfer mold made from fine metal mesh paper pulp to be made the wet base of paper pulp earlier, and the transfer mold that will have the wet base of paper pulp is then inserted thermocompression forming in the hot press, the typing back demoulding.Because the withstand voltage and support force of fine wire is limited, so this kind production technology can only be produced small-sized paper pulp molded product such as disposable fast food tool.Another kind then is to apply on mould with wire netting, and by preformed behind the vacuum suction slurry, entering after the wet demoulding of moulding that the drying box inner drying becomes product or be dried to moisture content is the dry forming of finalizing the design once more behind 30% the wet base, and then cuts edge.This production technology then must will wet base from mould, therefore also can only produce as products such as egg holder, disposable snack box, back yard industry packing materials.The above two kinds of paper pulp mould production technology, owing to be subjected to restriction such as its production mould, (area is greater than 0.1m can't to produce large-scale paper pulp mould
2, thickness is greater than 0.5mm) product, as the packaging cushion of big machinery or electric equipment products, board-like or special-shaped furniture and disposable coffin for cremation etc., the scope of pulp molding product is restricted.
Summary of the invention:
Goal of the invention of the present utility model is can only produce the shortcoming of small-sized paper pulp molded product in order to solve existing in prior technology, and a kind of paper pulp mould mould of producing large-scale pulp molding product is provided.
Technical solution of the present utility model is: a kind of large-scale paper pulp mould mould, be provided with tire 1, the following tire 2 that is complementary with last tire 1 and place down the exhaust outlet device 3 that can join with vavuum pump below the tire 2, last tire 1 is built-in with heater 4, material chamber 5 is arranged in the following tire 2, and material has through hole 6 below the chamber 5.
Described heater 4 is for inserting the reciprocal pipeline of thermal source.
The pipeline spacing of described reciprocal pipeline equates and each pipeline equates with the vertical range of last tire lower surface.
Described exhaust outlet device 3 is airtight casing.
In the described airtight casing dividing plate 7 is arranged.
The utility model is compared with prior art has following advantage: can once finish moulding, the fixating shape step of pulp molding product, overcome the shortcoming of the post forming that prior art adopted, simplify production technology.Solve present pulp molding technology and can't produce the problem of large-scale paper pulp mould product, made the pulp molding technology scope of application wider, can produce the pulp molding goods of different shape.
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the vertical view of tire on the utility model embodiment.
The specific embodiment:
Below in conjunction with the description of drawings specific embodiment of the present utility model.As shown in Figure 1, 2: be provided with tire 1, last tire 1 is built-in with heater 4, heater 4 is for inserting the reciprocal pipeline of thermal source, and the pipeline spacing of reciprocal pipeline equates and each pipeline equates with the vertical range of last tire lower surface, makes the homogeneous heating of 4 pairs of molds of heater.Its thermal source can be electrical heating elements or steam, and promptly 2 can go into electrical heating elements or adopt steam to heat by the mode of reciprocal pipeline in that reciprocal pipeline is mid-.As can be seen from Figure 1, the following tire 2 that is complementary with last tire 1 bottom shape is arranged, material chamber 5 is arranged in the following tire 2, material has through hole 6 below the chamber 5.Below following tire 2, also be connected to the exhaust outlet device 3 that can join with vavuum pump, promptly airtight casing.For making the vacuum in the casing even, dividing plate 7 can be set in airtight casing.
When suppressing large-scale paper pulp mould, paper pulp is placed on down on the wire nettings 8 set in the material chamber 5 of tire 2, makes the compacting that is interlocked of tire and play tire, extrude the moisture content in the paper pulp, set through hole 6 discharges in the tire 2 under the water of extruding passes through.Simultaneously, the wet base heating of the 4 pairs of paper pulp of heater in the last tire; Vavuum pump is also worked simultaneously, and the steam that produces when water that extraction is extruded and heating is till the wet base of paper pulp reaches degree of drying.
