Abstract
The utility model discloses a middle rod section-difference forming device comprising a female die with a through hole, an upper die and a lower die, wherein the upper die and the lower die fixed with the female die into a whole for forming a die cavity is arranged in the through hole, and a middle rod is sheathed in the lower die. The utility model is characterized in that a slot is arranged at the side wall of the lower die; a convex block is arranged on the middle rod; and the convex block is matched with the corresponding slot to enable the upper die, the lower die, the female die and the middle rod to form the die cavity. The utility model can avoid a phenomenon that an electronic component core is deformed seriously finally caused by unevenly pressure because of uneven packing when powder is formed, and improve the product fine rate; however, the middle rod can move in the lower die thereby adjusting the convex block in the corresponding position of the slot, and thus, the line slot depth is adjusted arbitrarily to satisfy the forming requirements of the electronic component core for different line slot depths.
Description
Technical field
The utility model belongs to the field shaping technique of powder compacting, particularly relates to a kind of shaped device that is mainly used in electronic building brick core (core).
Background technology
The shaped device of traditional electronic building brick core (core) comprises the master mold of a coherent through hole, the upper die and lower die that in through hole, are fixed as one for formation die cavity and described master mold, be set with middle rod in the counterdie, be provided with in the end of patrix to form the projection of electronic building brick core (core) product wire casing.When adopting this device can appear at the powder moulding since filler inhomogeneous, cause pressure inhomogeneous, and finally cause the serious phenomenon of electronic building brick core (core) distortion, thereby the fraction defective of product is improved; And when moulding has the electronic building brick core (core) of the different wire casing degree of depth, need change patrix, thereby make troubles to operation.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of section-differential shaped device of middle rod that prevents electronic building brick core (core) distortion and can satisfy electronic building brick core (core) the moulding needs of the different wire casing degree of depth.
The technical scheme that its technical problem that solves the utility model adopts is:
Excellent section-differential shaped device in a kind of, the master mold that comprises a coherent through hole, the upper die and lower die that in through hole, are fixed as one for formation die cavity and described master mold, be set with middle rod in the counterdie, the sidewall that it is characterized in that described counterdie is provided with short slot, middle rod is provided with projection, and described projection and corresponding short slot cooperation are so that form described die cavity between upper die and lower die, master mold and the middle rod.
The beneficial effects of the utility model are: when the utility model can be avoided appearing at the powder moulding since filler inhomogeneous, cause pressure inhomogeneous, and finally cause the serious phenomenon of electronic building brick core (core) distortion, improve the acceptance rate of product, and middle rod can move in counterdie, reach and adjust the purpose of projection at the relative position of short slot, thereby regulate the wire casing degree of depth arbitrarily, to satisfy moulding needs to the electronic building brick core (core) of the different wire casing degree of depth.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a perspective exploded view of the present utility model;
Fig. 2 is the perspective exploded view of middle rod when cooperating with counterdie.
The specific embodiment
With reference to Fig. 1, Fig. 2, the utility model disclosed a kind of in excellent section-differential shaped device, the master mold 1 that comprises a coherent through hole 2, the patrix 3 and the counterdie 4 that in through hole 2, are fixed as one for formation die cavity and described master mold 1, in counterdie 4 and patrix 3, be provided with through hole 5, the interior hole shape of these through hole 5 visible electronic assembly cores (core) and deciding, when being shaped as circle as the endoporus when electronic building brick core (core), this through hole then is arranged to circle.Rod 6 in counterdie 4, being set with, one end of middle rod 6 can insert in the through hole of patrix 3, sidewall at counterdie 4 is provided with short slot 7, the wire casing quantity of the quantity visible electronic assembly core (core) of short slot and deciding, in rod 6 be provided with corresponding projection 8, projection 8 cooperates with corresponding short slot, and by excellent position-adjustable projection in counterdie in the adjustment in the position of short slot, with any adjusting wire casing degree of depth, satisfy moulding needs to the electronic building brick core (core) of the different wire casing degree of depth.After upper die and lower die, master mold and middle rod assembling, the described die cavity of formation between the rod during upper die and lower die, master mold reach.
When the utility model can be avoided appearing at the powder moulding since filler inhomogeneous, cause pressure inhomogeneous, and finally cause the serious phenomenon of electronic building brick core (core) distortion, improve the acceptance rate of product, and because any cooperation the between projection and the short slot, can regulate the wire casing degree of depth arbitrarily, to satisfy moulding needs to the electronic building brick core (core) of the different wire casing degree of depth.
