In the technical program, by adopting the through hole shaping dies being formed by lower die-sleeve, die cavity, interior die sleeve, axle and Upper Die-sleeve, realized thering is the shaping of the product that utilizes powder body material compacting of through hole, and by changing the outer contoured shape of medium and small half cover of interior die sleeve and more than half cover, just can realize the compacting of the product of the various difformity through holes such as square to having, circular, polygon, the through-hole surfaces suppressing can reach exempts from the effect of processing.In utilizing, the structure of die sleeve and axle has realized the shaping of through-hole surfaces, has realized smoothly the mould that moves back of through hole inner ring surface by medium and small half cover of interior die sleeve and the relation of more than half cover.
Further technical scheme is, described through hole is comprised of interconnective upper taper hole and lower cone hole.
In the technical program, by adopting the through hole formed by upper taper hole and lower cone hole, realized thering is the processing of through hole in the product of through hole.
Further technical scheme is, described smaller part cover forms the first combinatorial surface with the position that is most enclosed within described interior die sleeve periphery.
Further technical scheme is, described smaller part cover and be most enclosed within the position that described internal mold puts through hole and form the second combinatorial surface.
The technical program has formed the combinatorial surface of smaller part cover with more than half cover jointly by the first combinatorial surface and the second combinatorial surface forming, the through hole that this combinatorial surface just can be realized product moves back mould smoothly, while moving back mould, to axis direction, knock gently the smaller part cover of interior die sleeve, by this combinatorial surface by moving in its inside die sleeve central through hole, realize the separated of smaller part cover and more than half cover, thereby realize the mould that moves back of interiors of products through hole.
Further technical scheme is, the position that described die cavity is connected with axle at it is provided with the conical surface and the lower conical surface.
Further technical scheme is, described axle is comprised of identical upper end and bottom, and described upper end and the described upper conical surface match, and matches with the described lower conical surface in described bottom.
The technical program central shaft is comprised of the identical upper end of structure and bottom, and axle upper end and bottom manufacture by the conical surface up and down of inside cavity respectively, and contact area is greater than 80%, and axle upper end contacts well with bottom.
Compared with prior art, the beneficial effects of the utility model are:
Adopt mould in the utility model by waiting mode of static pressure just can realize thering is product compressing of through hole, and the through-hole surfaces suppressing can reach and exempt from the effect of processing.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of the through hole shaping dies of a kind of embodiment of the utility model.
Fig. 2 be in the through hole shaping dies of a kind of embodiment of the utility model in the local enlarged diagram of die sleeve.
As shown in the figure:
1 lower die-sleeve, 2 die cavitys, 3 interior die sleeves, 4 axles, 5 Upper Die-sleeves, 6 smaller part covers, 7 most overlap.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further elaborated.
As depicted in figs. 1 and 2, a kind of through hole shaping dies, comprise lower die-sleeve 1, die cavity 2, interior die sleeve 3, axle 4 and Upper Die-sleeve 5, between described lower die-sleeve 1 and Upper Die-sleeve 5, form a cavity, described cavity is die cavity 2, in described die cavity 2, be provided with axle 4, described axle 4 two ends are fixedly connected with interior die sleeve 3 by screw, described interior die sleeve 3 is by smaller part cover 6 and more than half cover 7 forms and described interior die sleeve 3 centers are provided with through hole, described through hole is comprised of interconnective upper taper hole and lower cone hole, described smaller part cover 6 and more than half cover 7 form the first combinatorial surface in the position of described interior die sleeve 3 periphery, described smaller part cover 6 and more than half cover 7 position of through hole on described interior die sleeve 3 form the second combinatorial surface, the position that described die cavity 2 is connected with axle 4 at it is provided with the conical surface and the lower conical surface, described axle 4 is comprised of identical upper end and bottom, and described upper end and the described upper conical surface match, match with the described lower conical surface in described bottom.
Operation principle of the present utility model is as follows:
Through hole shaping dies mainly consists of jointly lower die-sleeve 1, die cavity 2, interior die sleeve 3, axle 4 and Upper Die-sleeve 5, thereby coordinates die cavity 2 and interior die sleeve 3 can realize the compacting of powder body material with lower die-sleeve 1 by extruding Upper Die-sleeve 5.
The main inner die sleeve 3 of shaping of product through hole is realized, and between interior die sleeve 3 and axle 4, is connected by screw, and while moving back mould, first removes the screw that connects axle 4 and interior die sleeve 3, then uses jacking screw just can realize axle 4 separated with interior die sleeve 3.
The structure of interior die sleeve 3 and move back modulus principle for convenience of explanation, the cylindrical hole of take in product describes as example, interior die sleeve 3 centers form through hole by upper and lower two bellmouths, be connected with axle 4 is supporting respectively, interior die sleeve 3 is comprised of smaller part cover 6 and more than half cover 7 two parts, and smaller part cover 6 with most overlap 7 and by identical two, form respectively; It at the smaller part cover 6 of the position of interior die sleeve 3 periphery and contact-making surface between more than half cover 7, is the first combinatorial surface of the two planes formation that are parallel to each other, contact-making surface on interior die sleeve 3 between the smaller part of the position of through hole cover 6 and more than half cover 7 is that two planes with certain angle form the second combinatorial surface, and the first combinatorial surface and the second combinatorial surface have formed the combinatorial surface of smaller part cover 6 and more than half cover 7 jointly, what this combinatorial surface just can have been realized product inner via hole moves back mould smoothly.While moving back mould, to axis direction, knock gently the smaller part cover 6 of interior die sleeve 3, by combinatorial surface, by it, in central through hole, move, realize the separated of smaller part cover 6 and more than half cover 7, thereby realize the mould that moves back of interiors of products through hole.
