Abstract
The utility model discloses an isopressing ball forming die, belongs to the field of dies and specifically relates to an isopressing die. The isopressing ball forming die comprises an upper die and a lower die, wherein forming cavities of the upper die and the lower die are buckled for constituting a spherical cavity; and the isopressing ball forming die is characterized in that a bell mouth is formed on the lower die, the upper die is inserted into the lower die, and the forming cavities of the upper die and the lower die are two spherical crown-shaped cavities with different sizes. A grinding ball produced by the die is perfectly round in appearance and balanced in various stress in the grinding ball, and the service life and the durable tolerance are significantly improved.
Description
Technical field
The utility model belongs to mould applications, is specifically related to a kind of isostatic tooling.
Background technology
At present, with the mill ball of powder pressing forming, its mould therefor mostly is the rigidity material and makes, on upper and lower mould, offer hemispherical forming cavity respectively, on counterdie, place material powder, utilize press that upper and lower mould is pressed together behind the fastening patrix, thereby make the powder pressing in the die cavity become spheroid.It is suitable and homogeneous is constant that the mill ball that this molding mode is produced, its quality depend on the placement amount of powder, otherwise the spheroid density inequality of moulding can produce groove or because of blowing too much is pressed into spheroid, influence Grinding Quality when serious because lack material.And, owing to only be subjected to the pressure forming of both direction, and the every stress distribution inequality in the ball, experience bump to a certain degree in grinder promptly may be along intermediate section profile cracking into two.
The utility model content
The technical problem that the utility model solved is: design a kind of static pressure balling-up mould that waits, can improve the Forming Quality of mill ball.
The technical scheme that its technical problem that will solve the utility model adopts is: design a kind of static pressure balling-up mould that waits, comprise upper die and lower die, the forming cavity of upper die and lower die fastens forms spherical hollow space, it is characterized in that on counterdie, offering horn mouth, patrix inserts in the counterdie, and the forming cavity of upper die and lower die is two anisometric spherical cavitys.
A kind of static pressure balling-up mould that waits described in the utility model, the spherical crown height that it is characterized in that the patrix forming cavity is the 1/3-1/5 that upper and lower mould fastens the spherical forming cavity diameter of forming.
Upper and lower mould of the present utility model is made for the rubber material.
The beneficial effect that the utility model had is:
1. patrix of the present utility model inserts in the counterdie, the forming cavity of upper die and lower die is two anisometric spherical cavitys, during use, earlier a certain amount of material powder is placed in the counterdie, patrix is covered, equivalent applies hydraulic pressure around mould, promptly wait static pressure, the powder in the spherical forming cavity can be pressed into ball-type, and the mill ball appearance that this mould is produced is perfectly round, inner every stress equilibrium, service life and durable tolerance are significantly improved.
2. the spherical crown height of patrix forming cavity is the 1/3-1/5 that upper and lower mould fastens the spherical forming cavity diameter of forming, make the major part of moulding spheroid be wrapped up by counterdie, more durable after waiting hydrostatic pressure condition compacted under, after the moulding depanning smooth, can be at when bump cracking.
3. upper and lower mould is made for the rubber material, can give material powder with the fluid pressure conduction uniformly of outside, makes that the spheroid internal stress after the moulding is balanced more.
4. the utility model is simple in structure, and is easy to use, and the low and good product quality produced of cost of manufacture is suitablely in the industry cycle promoted the use of.
Description of drawings
Fig. 1 is the structural representation of the utility model patrix;
Fig. 2 is the structural representation of the utility model counterdie;
Among the figure: 1. patrix, 2. counterdie.
The specific embodiment
As shown in the figure, a kind of static pressure balling-up mould that waits described in the utility model, on counterdie 2, offer horn mouth, patrix 1 inserts in the counterdie 2, forming cavity on patrix 1 and the counterdie 2 is two anisometric spherical cavitys, wherein, the spherical crown height of patrix 1 forming cavity is 1/4 (also can be 1/3 or 1/5) that upper and lower mould fastens the spherical forming cavity diameter of forming.Upper and lower mould is made for the rubber material, can give material powder with the fluid pressure conduction uniformly of outside, makes that the spheroid internal stress after the moulding is balanced more.During use, earlier a certain amount of material powder is placed in the counterdie 2, patrix 1 is covered, equivalent applies hydraulic pressure around mould, promptly waits static pressure, and the powder in the spherical forming cavity can be pressed into ball-type, the mill ball appearance that this mould is produced is perfectly round, inner every stress equilibrium can not collide cracking in grinder, service life and durable tolerance are significantly improved.
It is to be noted; above-mentioned embodiment only is the utility model preferred embodiment; for those skilled in the art, under the prerequisite that meets the utility model operation principle, any be equal to or similar replacement all falls in the protection domain of the present utility model.
Claims (3)
1. one kind is waited static pressure balling-up mould, comprises upper die and lower die, and the forming cavity of upper die and lower die fastens forms spherical hollow space, it is characterized in that offering on counterdie horn mouth, and patrix inserts in the counterdie, and the forming cavity of upper die and lower die is two anisometric spherical cavitys.
2. a kind of static pressure balling-up mould that waits according to claim 1, the spherical crown height that it is characterized in that the patrix forming cavity is the 1/3-1/5 that upper and lower mould fastens the spherical forming cavity diameter of forming.
3. a kind of static pressure balling-up mould that waits according to claim 1 and 2 is characterized in that upper and lower mould is the making of rubber material.
