Abstract

The utility model relates to a mould for press cakes of shale-paraffin flour, which is composed of a mandrel (5), an upper press mold (1), a dip mold (7), a module (3) outside the upper press mold and the dip mold, a pretightening sleeve (4) for locking the module (3) and a movable pallet between the dip mold and the module. The utility model is characterized in that stages for limiting feed quantity (2) (8) positioned by the module (3) are respectively arranged on the upper press mold (1) and the dip mold (7). The mould for press cakes of shale-paraffin flour is compressed for two times, and strokes of the upper press mold and the dip mold are allocated reasonably, so the phenomena, such as nonuniform density and napping can not occur. Thus, the quality and the dimensional precision of the press cakes of shale-paraffin flour are ensured and the service life of a mould is increased.

Description

The mould of fissile-wax stone briquetting

The utility model relates to utilization and is below or above the method that atmospheric pressure makes material generation chemistry or physical change, its relevant devices, particularly adamantine formation and equipment thereof.

Parts commonly used when static state is produced diamond are fissile-wax stone briquetting (extrusion dies), at present, the mould of compacting fissile-wax stone briquetting, when compacting, mostly be unidirectional, be top die in module to pressing down row, therefore make briquetting top density big, bottom density is little, density unevenness is even, simultaneously, because of top under pressure to descending, cause module inner surface and fissile-wax stone surface galling phenomenon, influence die life and briquetting quality, for addressing the above problem, disclose a kind of twice pressurization and suppressed the mould of fissile-wax stone briquetting, it is to be added with a supporting plate that can shift out easily at dip mold and intermodule, under the situation of band supporting plate, carry out the compacting first time, top die is descending, because supporting plate is arranged, the dip mold up stroke is restricted, remove supporting plate then, carry out second time compacting, this moment, dip mold can be up and put in place, therefore can make, the stroke of two pressing molds in module is basic identical down, make on the briquetting lower density evenly and avoided the plucking phenomenon, but this kind mould when compacting size be difficult for grasping, the stroke of top die is wayward when suppressing for the first time, particularly when the concave station that status requirement is arranged on the briquetting etc., can not reach required precision, still have density big phenomenon in top to exist on the briquetting.

It is more even that the purpose of this utility model provides a kind of fissile-wax stone briquetting density that can make, and size is accurate, the mould of easy to operate fissile-wax stone briquetting.

The purpose of this utility model realizes by following technical scheme, the mould of fissile-wax stone briquetting has axle, at axle one end top die slidably, be loaded on the dip mold of axle other end certain position, module in upper and lower pressing mold outside, the tight cover that gives with the module latch location, extensible supporting plate between the end face of dip mold and module, it is characterized in that having on the said top die the amount of being pressed into limiting stand, the amount of the being pressed into limiting stand with the module location is arranged on said dip mold with the module location.

During compacting, have supporting plate and carry out the compacting first time, top die is put in place in module, shift out supporting plate, carry out the compacting second time, dip mold is put in place, because the reasonable distribution of stroke makes the two ends decrement basic identical in module, briquetting density is even, can not produce the plucking phenomenon, improve briquetting quality and die life, guarantee that the size of briquetting is accurate yet.

Be described in detail below in conjunction with the mould of drawings and Examples fissile-wax stone briquetting of the present utility model.

Fig. 1 is the structural representation of mould before compacting of the utility model fissile-wax stone briquetting;

Fig. 2 is the structural representation of mould after compacting of the utility model fissile-wax stone briquetting, shows the situation of mould when having localized variation or side that concave station is arranged on the fissile-wax stone powder agglomates simultaneously.

As Fig. 1, the mould of this fissile-wax stone briquetting has an axle 5, top die 1 slidably is equipped with in axle 5 upper ends, (for example locating with step) is equipped with dip mold 7 on the axle 5 lower end certain positions, last, dip mold has module 3 outward, module 3 inner chambers have the die cavity that constitutes four sides of fissile-wax stone briquetting, axle 5, top die 1, dip mold 7, put into the fissile-wax stone briquetting that promptly can be made into the definite shape size after the fissile-wax stone powder is suppressed in the space between the module 3, module 3 is made up of conveniently to take apart and depanning 2-4 piece template, module 3 lateral surfaces become cone, it is outer to be equipped with one has the tight cover 4 of giving of taper hole with matching and with module 3 lockings, between the lower surface and dip mold 7 of module, dip mold is with the supporting plate 9 that can conveniently extract out outward, for example an example of supporting plate 9 has opening 10 and can shift out from dip mold 7, the amount of being pressed into limiting stand 2 is arranged on top die 1, it is abutted against the location with the upper surface of module 3, the amount of being pressed into limiting stand 8 is arranged on dip mold 7, it is abutted against the location with the lower surface of module 3, therefore makes on the row, it is very accurate and guaranteed the size of briquetting and guaranteed that density is more even that dip mold is pressed into the position of module 3.

Axle 5, top die 1, the cavity surface of dip mold 7 and module 3 should change according to the desired shape of fissile-wax stone briquetting, Fig. 1 illustrates six of compacting outsides and is the plane, endoporus is the mould of the fissile-wax stone briquetting of unthreaded hole, and in Fig. 2, show a kind of endoporus one end and have step, have also to have on the outside of platform one end and place the mould of fissile-wax stone briquetting that electrode stretches out the concave station on ring limit, so this mould has step 12 on axle 5, it can extrude the step of fissile-wax stone briquetting endoporus one end, and boss 11 is arranged on top die, it can extrude and place the concave station that electrode stretches out the ring limit on the fissile-wax stone piece.On four sides of briquetting the concave station that is suitable for the press top hammer head can also be arranged, so can on module 3 inner surfaces boss 13 be arranged, it can extrude the concave station that is suitable for the press top hammer head on four sides of fissile-wax stone briquetting.

During compacting, mould is all assembled except that top die 1, then quantitative fissile-wax stone powder is put into die cavity, load onto top die 1, carry out the compacting first time, top die 1 descending putting in place, after removing pressure supporting plate 9 is shifted out, the compacting second time is carried out in pressurization again, owing to shift out supporting plate 9, module is up so dip mold 7 is relative puts in place, because supporting plate 9 is arranged, make horizontal piece 3 not relatively dip mold fall, guaranteed that top die is can stroke when suppressing the first time not oversize, because it is last, the reasonable distribution of dip mold stroke, make that fissile-wax stone powder pressurized in die cavity is even, so density is even, also can the generating unit dividing potential drop get tension and make the surface plucking phenomenon occur, the size that guarantees the fissile-wax stone briquetting simultaneously is accurate, also makes pressing operation very convenient.
