A kind of eight-plate iron core die frame
Technical field
The utility model relates to a kind of moulding frame used for powder compression moulding machine, relates in particular to a kind of eight layers of template powder pressing forming mould bases.
Background technology
Powder metallurgy mould is the mould with the solid metal powder pressing.During work, pour metal dust into counterdie quantitatively, then patrix depress, closed, be shaped, eject prefabricated blank with Lifting Device again, and send into sintering in the sintering furnace, make powdered metal parts then.
The space of general metallic sintered products is very big, accounts for about 15% of cumulative volume, and forming pressure is little.Because this body structure of mould is simpler, cost is lower, but the shortcoming of its existence also is apparently, shortcoming such as, the surface roughness lower as its element precision that processes.
Therefore, there is above weak point in the powder metallurgy die of prior art, how to suppress under the prerequisite of quality at the assurance powdered metal parts, and developing optimum powder metallurgy die carrier is the problem that powdered metal parts manufacturer is concerned about most.
The utility model content
The purpose of this utility model is to provide a kind of eight-plate iron core die frame, has the compacting advantage of high precision.
The technical solution of the utility model is, a kind of eight-plate iron core die frame, comprise a patrix and a counterdie, be reserved with the space that is used for shaped article between described patrix and the counterdie, wherein, described patrix is mainly by upper bolster, upper padding plate, upper mounted plate, stripper is formed from top to bottom, and wherein, described counterdie is by lower bolster, bottom plate, lower bolster, die shoe overlaps successively and puts, described upper bolster, upper padding plate, upper mounted plate, stripper, lower bolster, bottom plate, lower bolster and die shoe are provided with the guide hole of mutual correspondence, outer guiding post passes the guide hole of each template, and each template is interconnected; Described mould bases also comprises first, second inner guiding post, and first inner guiding post connects upper mounted plate and stripper, and upper mounted plate further is connected with stripper; And second inner guiding post connects lower bolster and bottom plate, and lower bolster further is connected with bottom plate.
Preferentially, the quantity of described outer guiding post is four.
Preferentially, the quantity of described first inner guiding post is four, and the quantity of described second inner guiding post is four.
The eight-plate iron core die frame that the utility model discloses, because between upper mounted plate and stripper, and between lower bolster and bottom plate, be respectively arranged with inner guiding post, therefore on original outer guiding post connection basis, further improved the precision between upper mounted plate and the stripper, and the precision between lower bolster and the bottom plate, correspondingly, also improved the precision of compacted part.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the utility model eight-plate iron core die frame example structure schematic diagram;
Fig. 2 is the utility model eight-plate iron core die frame guide pillar distribution map;
The mark of each parts is as follows in the accompanying drawing: 100 diels, 110 patrixes, 111 upper bolsters, 112 upper padding plates, 113 upper mounted plates, 114 strippers, 120 counterdies, 121 lower bolsters, 121,122 bottom plates, 123 lower bolsters, 124 die shoes, 130 outer guiding posts, 140 first inner guiding posts, 150 second inner guiding posts, 160 iron cores, 170 contiguous blocks, 180 connecting rods.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby protection domain of the present utility model is made more explicit defining so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that.
Fig. 1 is the utility model eight-plate iron core die frame, and the iron core die frame shown in the figure mainly comprises patrix 110 and counterdie 120, and patrix 110 is arranged from top to bottom successively by upper bolster 111, upper padding plate 112, upper mounted plate 113, stripper 114 and formed; Counterdie 120 is arranged equally successively from top to bottom by lower bolster 121, bottom plate 122, lower bolster 123, die shoe 124.In addition, iron core die frame also comprises, outer guiding post 130, inner guiding post, iron core 160, oil cylinder (not shown), contiguous block 170, connecting rod 180.
Position that each member is concrete and annexation are: the mould bases top is followed successively by to the bottom and is upper bolster 111, upper padding plate 112, upper mounted plate 113, stripper 114, lower bolster 121, bottom plate 122, lower bolster 123 and die shoe 124.Each piece template is provided with the guide hole of mutual correspondence, and guide hole is used to wear outer guiding post 130, and in other words, outer guiding post 130 interconnects each template by guide hole, and the position that guarantees each piece template meets and preestablishes requirement.In addition, the utility model innovation part is also set up first inner guiding post 140 and second inner guiding post 150 on mould bases, wherein first inner guiding post 140 is arranged between upper mounted plate 113 and the stripper 114, and wherein, second inner guiding post 150 is arranged between lower bolster 121 and the bottom plate 122.Iron core 160 is arranged at module central authorities, oil cylinder has a plurality of, want to connect with disparate modules respectively, because the distribution technique of oil cylinder is the known technology of this area, again, this technology is not an innovation part of the present utility model, Gu the applicant is not to its detailed description, contiguous block is arranged on the bottom plate, and connecting rod 180 1 ends link to each other with iron core 160, and the other end links to each other with contiguous block 170.
As a preferential embodiment of the present utility model, among the utility model embodiment, the quantity of outer guiding post 130 is four, similarly be, the quantity of first inner guiding post 140 is four, and the quantity of second inner guiding post 150 also is four, the distribution mode of guide pillar is seen shown in Figure 2, be apparently, outer guiding post is arranged at the template outside respectively, and inner guiding post (comprising first inner guiding post and second inner guiding post) is arranged at the template inboard respectively.
The eight-plate iron core die frame that the utility model discloses, because between upper mounted plate 113 and stripper 114, and between lower bolster 121 and bottom plate 122, be respectively arranged with inner guiding post, therefore on original outer guiding post 130 connection basis, further improved the precision between upper mounted plate 113 and the stripper 114, and the precision between lower bolster 121 and the bottom plate 122, correspondingly, also improved the precision of compacted part.
The above; it only is the specific embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; any those of ordinary skill in the art are in the disclosed technical scope of the utility model; variation or the replacement that can expect without creative work all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
