Abstract
The utility model discloses an Sm-Co product molding bidirectional press mould which belongs to the processing device of magnet products and comprises a top die (1), a lower die (2), a cavity (3) and a base, wherein the top die (1) and the lower die (2) are respectively positioned above and below the cavity (3); the base is positioned below the cavity (3) and is a spring base (4); by changing the squeeze film base into the spring base, when the top die moves downwards under the action of the acting force, the spring base is also subjected to the downward force and generates upward reacting force randomly to realize up and down bidirectional pressure on the blank between the top die and the lower die to press the blank, therefore, the molded product does not have up and down density contrast, and the product quality is improved; the spring in the spring base is in dropping blocking, thus being capable of being replaced according to the return pressure size; and the Sm-Co product molding bidirectional press mould has simple structure and small volume, and is applicable to industrialized production and easy to promote.
Description
Technical field
The utility model relates to the processing unit (plant) of permanent magnet product, a kind of Sm-Co formed product double acting die of saying so more specifically.
Background technology
The processing mode of Sm-Co permanent magnet product is for to be processed as specific solid shape with Powdered by die arrangement, the structure of used film pressing device is varied when processing Sm-Co permanent magnet product, its principle is that Sm-Co powder moulding plain draw mold is unidirectional from the top down compacting, specifically see shown in Figure 1, the blank difference of densities that patrix 1 and counterdie 2 lay respectively at the top of die cavity 3 and below compression moulding is very big, it is inhomogeneous directly to constitute the product magnetic property, cause Sm-Co permanent magnet product quality to descend, and its production efficiency also can descend under the bigger situation of production lot.
The utility model content
The purpose of this utility model is to solve above-mentioned deficiency, provides a kind of and has and can carry out a kind of Sm-Co formed product double acting die of two-way press process up and down to the compacting blank.
For solving above-mentioned technical problem, the utility model by the following technical solutions:
Sm-Co formed product double acting die of the present utility model comprises upper die and lower die, die cavity and base, and patrix and counterdie lay respectively at the top and the below of die cavity, and base is positioned at the die cavity below, and described base is a spring base.
Further technical scheme is: described spring base is positioned at the both sides of counterdie, and the downward active force that spring base will come from patrix is converted to active force upwards.
Further technical scheme is: the built-in Spring Card of described spring base is combined in its inner chamber, and spring is the shape that comes off, and can change the different spring of elastic force according to the size of reaction force.
Compared with prior art, the beneficial effects of the utility model are: after replacing with spring pedestal by the base with press mold, be used as when enforcing patrix and moving down, spring pedestal also is subjected to downward power, it produces reaction force upwards at random, blank between patrix and the counterdie is realized that two-way pressure is suppressed it up and down, make the product after the moulding that difference of densities whenever be arranged, improve the quality of products, therefore the spring in the spring pedestal can be changed according to the back pressure size for the shape engaging that comes off, and Sm-Co formed product double acting die of the present utility model is simple in structure, volume is less, is suitable for suitability for industrialized production, is easy to promote.
Description of drawings
Fig. 1 is the press mold structural representation of traditional structure;
Fig. 2 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further elaborated.
As shown in Figure 2, a kind of Sm-Co formed product double acting die of the present utility model, formed with base by patrix 1, counterdie 2, die cavity 3, patrix 1 and counterdie 2 lay respectively at the top and the below of die cavity 3, and base is positioned at die cavity 3 belows, and wherein base adopts spring base 4, spring base 4 is positioned at the both sides of counterdie 2, spring base 4 built-in Spring Cards are combined in its inner chamber, and spring is the shape that comes off, according to the spring of the big or small replaceable different elastic force of required reaction force.
A kind of Sm-Co formed product double acting die of the present utility model in use, at first will suppress blank is placed in the die cavity 3 between patrix 1 and the counterdie 2, again patrix is applied downward active force, die cavity 3 is subjected to moving down behind the downward active force, spring in the spring base 4 is subjected to can producing reaction force upwards behind the downward active force, and then in the die cavity 3 between patrix 1 and the counterdie 2 compacting blank suppress, reach the purpose of the blank product being carried out two-way compacting.
Claims (3)
1. Sm-Co formed product double acting die, comprise patrix (1), counterdie (2), die cavity (3) and base, patrix (1) and counterdie (2) lay respectively at the top and the below of die cavity (3), and base is positioned at die cavity (3) below, and it is characterized in that: described base is spring base (4).
2. Sm-Co formed product double acting die according to claim 1 is characterized in that: described spring base (4) is positioned at the both sides of counterdie (2).
3. Sm-Co formed product double acting die according to claim 1 is characterized in that: the built-in Spring Card of described spring base (4) is combined in its inner chamber, and spring is the shape that comes off.
