The utility model is characterized in that both a basic die and a working surface are combined into one whole body. A net cover is not arranged in the structure. The utility model is shaped through sintering, drying or heating by the porous materials of the ceramic, the river sand, the carborundum, the iron sand or the plastic grain, etc. The utility model is manufactured by the whole body. The utility model is not required to assemble. The utility model has the advantages of short periodicity, low cost and long service life. The utility model can be made into the abnormal shapes with complicated shapes. The device solves the defects that in the prior art the metal die has large mechanical processing quantity, the net cover is easy to damage, the life time is short, the utility model only manufactures products with simple shapes, etc.
Description
The present invention relates to a kind ofly belong to that the packing articles industry uses, microporous mould for paper pulp plastics-sucking forming.
It is raw material with the old paper stock that China is promoting a kind of, with the novel package goods of plastics sucking moulding manufactured.
Paper pulp plastic uptake technology is to be raw material with the old paper stock, and pattern tool plastics sucking moulding is used for the Production and Packaging goods.
Its technical process is:
Waste paper is processed into liquid paper pulp, adds other batching, and compressed air stirring makes into uniform hybrid state; The working surface of die immerses in the slurries, paper pulp is adsorbed onto on the guard of mould by negative pressure, forms a paper mold identical with the guard shape, and after mould proposed liquid level, negative pressure continued the suction paper mold and reduces to 10～20% until its water content; Then, punch contacts with die, and compressed air blows to paper mold on the punch, and at this moment, punch is also taken out negative pressure, and paper mold is held; When receiver was divided a word with a hyphen at the end of a line the punch below, the punch blowing compressed air blew to paper mold on the receiver (simultaneously, die begins descending, enters next circulation, goes round and begins again), and drying, arrangement get product.
Its mould is to constitute one group of combinable active unit by a pair of punch and die.Each punch (or die) mainly is made up of basic mode and working surface two parts:
A. be skeleton by steel with passage or copper basic mode,
B. its working surface is the foraminous net cover that one deck is being inlayed, and it is:
It is (1) stamping forming,
(2) copper or stainless steel,
(3) shape is simple arc,
(4) removable, be crimped on the outer surface of basic mode by bolt,
Basic mode is by casting, and grouping is through machining; Foraminous net cover be copper or stainless sheet steel through special steel mold punch forming, be embedded in the basic mode surface again, the working surface during as plastic uptake.
Size is as required organized unit splicing in a framework more, becomes a unitary mould, can use.
There is following deficiency in prior art:
1. material all is a metal, need cast and machined expense big (3～50,000 yuan), cycle long (3～5 months) during manufacturing; And not acid and alkali resistance.
2. as the metal porous guard of plastic uptake working surface, be that to be crimped on basic mode by bolt lip-deep, when on the large tracts of land plastics suction mould, using, cannot stand the air-flow repeated stock, easily break away from basic mode and be out of shape.So punch or die all are designed to the active unit form of dividing into groups, and to reduce the area of crimping guard, more a plurality of unit are assembled into whole plastic uptake mould.The produced plastic uptake product of such mould, surface all have many seams to exist, and influence product appearance.
3. foraminous net cover stands the impact of air-flow repeatedly in operating process, easily plays thorn, breaks, and service life is short.
4. only there is the sieve aperture about 200 on each basic mode surface, causes the paper mold gage distortion, and yield rate has only about 90%.
5. guard only can be made simple arc, causes product single (egg holder, apple holder etc. are arranged at present), develops new product and has any problem.
Purpose of the present invention is exactly to overcome the above-mentioned defective that exists in the prior art, for the domestic paper-plastic package production line that newly starts, provides a kind of improved microporous mould for paper pulp plastics-sucking forming, and mould provided by the invention has following advantage:
1. the work mould need not machined, can be with sintering or curing molding, and the use of can regenerating; Amount of machining such as framework and fixture is minimum.
2. the entire die integral manufacturing need not assembly unit, not only reduce labor intensity, and the no seam in paper products surface, outward appearance is good.
3. protruding (or recessed) mould be basic mode and working surface the two close as a wholely, the work mould of no guard on the structure, work mould are that poromerics constitutes, whole pressurized can not produce burr or breaks; All right alkaline-resisting, acidproof, the oil resistant of nonmetallic materials, so the life-span is long.
4. have numerous micropore, suction is even, and the paper mold thickness is even, good product quality, and yield rate can reach 100%.
5. can make the special-shaped mould of Any shape complexity, help the exploitation (as bottle holder, glassware holder, porcelain holder, instrument holder, instrument holder, drug bottle holder, handicraft holder, food holder, building and ornament materials holder, electrical equipment holder, television set, refrigerator and accessory holder thereof etc.) of various paper-plastic package goods new products.
Task of the present invention, realize by following means:
A kind of modified microporous mould for paper pulp plastics-sucking forming, its:
Protruding (or recessed) mould be basic mode and working surface the two close as a wholely, do not have net on the structure
The work mould of cover,
The work mould is that poromerics constitutes,
The entire die integral manufacturing need not assembly unit,
The working surface of protruding (or recessed) mould can be complex-shaped abnormity.
Above-mentioned microporous mould for paper pulp plastics-sucking forming is characterized in that the work mould can be that non-metal micro-holes material constitutes.
Above-mentioned microporous mould for paper pulp plastics-sucking forming is characterized in that the structure of work mould is, the granularity of the poromerics of basic mode part is 10～No. 20, and the granularity of the poromerics of working surface part is 25～No. 50, and the ratio of both thickness is: 8～20:2～0.5.
