Description
Technical field
This utility model relates to powder modeling technology area, is specifically related to a kind of powder moulding specific purpose tool.
Background technology
At present, anhydrous iron phosphate is to manufacture the main raw material(s) of lithium iron phosphate dynamic battery, moisture is the important safety parameter of electrokinetic cell, owing to LiFePO4 has extremely strong water absorption character, and higher rate of water absorption, this characteristic exists, and the humidity of air is bigger on its impact, and making LiFePO4 produce must be carried out in dry environment.The principal element of impact water suction is the specific surface area of material, and bigger specific surface area is the principal element of higher rate of water absorption.
Currently, tradition roasting technique, loads container (saggar) phosphate dihydrate ferrum (powder), with high temperature furnace roasting (general 500 DEG C-560 DEG C of sintering temperature), obtaining anhydrous iron phosphate after dehydration, the anhydrous iron phosphate specific surface area that this traditional handicraft obtains is at 20-30m2/ g, the biggest, and the greatest problem that traditional handicraft exists is: in roasting process, it is slower that container (saggar) piles up especially centre heat transmission at powder, the phosphate dihydrate ferrum (powder) steam in dehydration is difficult to quickly overflow from powder, rate of water loss is less, and the powder specific surface area after the sintering of container (saggar) centre is up to 30m2/ more than g, and the anhydrous iron phosphate specific surface area waving interval in container (saggar) is bigger.Even if sintering temperature is increased to greater than more than 600 DEG C, the powder on container (saggar) surface has burnt, but still there is heat transmission relaxation phenomenon in container (saggar) centre, the specific surface area of container (saggar) centre powder remains unchanged bigger, it is difficult to specific surface area to reduce, and restricts limited production efficiency.
Summary of the invention
For problem above, the utility model proposes a kind of structure design simple, reasonable, operate with simple and convenient, high rate of water loss can be realized, the specific surface area of powder can be effectively reduced, improve powder moulding efficiency and the powder moulding specific purpose tool of production efficiency.
This utility model is achieved through the following technical solutions:
Above-mentioned powder moulding specific purpose tool, including saggar body and the pattern that matches with described saggar body；Described saggar body is structure as a whole and middle part is provided with die cavity from top to bottom, and described pattern includes die cap, mould post and handle；Described mould post be uniformly laid in described die cap bottom and height the most identical with the cavity depth of described saggar body；Described handle is fixedly arranged on the top of described die cap；When powder moulding, described die cap coupling covers the die cavity mouth upper surface at described saggar body, and described mould post inserts powder and stretches to described mold cavity bottoms.
Described powder moulding specific purpose tool, wherein: the die cavity of described saggar body is square cavity body structure.
Described powder moulding specific purpose tool, wherein: described die cap is the die cavity mouth length of side that the length of square plate block structure and surrounding is longer than described saggar body.
Described powder moulding specific purpose tool, wherein: described handle is fixedly arranged on the center of top of described pattern.
Beneficial effect:
nullThe design of this utility model powder moulding specific purpose tool structure is simple、Rationally，It is on the basis of with existing container and roaster，Design the pattern matched with saggar body，Pattern is by die cap、Mould post and handle composition，When powder moulding，Die cap coupling covers the die cavity mouth upper surface at saggar body，Mould post inserts powder and stretches to mold cavity bottoms，After making the powder molding in die cavity，Pattern can be taken out from saggar body with being held by handle，Powder is the formation of the poroid moulding consistent with mould post，Now the powder after molding is the formation of multiple circular heat conduction passage identical with mould column diameter and height，This circle heat conduction passage can turn on heat bang path in powder high temperature dehydration environment，Reduce attenuation gradient，Ensure that heat is quickly transferred to each position, die cavity center and bottom，The steam that sintering process powder is taken off can overflow quickly through circular heat conduction passage，Thus，Achieve high rate of water loss，Reduce the specific surface area of powder，Whole tool operation is simple，Moulding efficiency is high、Effective，Production efficiency can be effectively improved.

Detailed description of the invention
As shown in Figures 1 to 4, this utility model powder moulding specific purpose tool, including saggar body 1 and pattern 2.
The cube structure that this saggar body 1 is integrated, offers square die cavity from top to bottom in the middle part of it；In the present embodiment, the thickness of this saggar body 1 surrounding die cavity wall is 11mm, and the length of side of die cavity is 320mm, and cavity depth is 120mm.
This pattern 2 matches with saggar body 1, and it includes die cap 21, mould post 22 and handle 23；Wherein, this die cap 21 is square plate block structure, and the die cavity length of side of its surrounding side ratio saggar body 1 is longer, and in the present embodiment, this die cap 21 is the plate structure of 330mm for the length of side；This mould post 22 has multiple and is uniformly laid in bottom this die cap 21, a diameter of 25mm of each mould post 22 in the present embodiment, and height is identical with the cavity depth of saggar body 1 is 120mm；Handle 23 is fixedly arranged on the center of top of this pattern 2.
During use, first fill up powder 3 by the die cavity of saggar body 1, then the handle 23 of pattern 2 it is held by, the mould post 22 of pattern 2 is inserted vertically into the powder in saggar body 1 die cavity, until being inserted into the bosom of saggar body 1 die cavity, now the surrounding, bottom of the die cap 21 of pattern 2 is pressed into contact with the die cavity mouth upper surface in saggar body 1；Then being taken out from saggar body 1 by pattern 2 with being held by handle 23, powder is the formation of the poroid moulding consistent with mould post, and now the powder after molding is the formation of multiple circular heat conduction passage 31 identical with mould post 22 diameter and height.
The design of this utility model structure is simple, reasonable, operates with simple and convenient, can realize high rate of water loss, can effectively reduce the specific surface area of powder, improves powder moulding efficiency, improve production efficiency, is suitable to promote and application.
