Abstract
The utility model discloses a powder metallurgy die which is convenient to manufacture and can improve processing accuracy. The powder metallurgy die comprises a die sleeve and a divided die core arranged in the die sleeve, wherein the die core comprises an upper die core and a lower die core; the outside surface of the upper die core is an cylinder surface, and the outside surface of the lower die core is a conical surface; the hole of the die sleeve is divided into two segments, wherein the upper segment is a column hole matched with the upper die core, and the lower segment is a conical hole matched with the lower die core; a jointing platform is arranged between the column hole and the conical hole. The powder metallurgy die is characterized in that the die core is designed into a divided structure, and the lower die core can be processed respectively, so that the processing difficulty is greatly reduced, and the processing accuracy is increased. The powder metallurgy die is particularly suitable for manufacturing powder metallurgy products with small steps.
Description
Technical field
The utility model relates to a kind of mould, refers more particularly to a kind of powder metallurgy mould.
Background technology
As everyone knows, the structure of powder metallurgy mould generally includes: die sleeve and be arranged on the core rod in die sleeve, the endoporus of core rod is with sintered metal product is corresponding accordingly.At some sintered metal products with tiny step of preparation, in the time making the core rod of answering in contrast, can only process by electric spark, process more difficultly, and machining accuracy is affected.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of can be easy to make, and can improve the powder metallurgy mould of machining accuracy.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of powder metallurgy mould, comprise: die sleeve and be arranged on the split type core rod in die sleeve, this core rod comprises: upper and lower core rod, and the outer surface of upper mold core is cylinder, the outer surface of lower mold core is taper surface, the hole of die sleeve is divided into two sections, epimere is the cylindrical hole matching with upper mold core, and hypomere is the bellmouth matching with lower mold core, between cylindrical hole and bellmouth, is provided with and is connected platform.
On the end face of described upper mold core, be provided with the positioning through hole that at least one pair of runs through upper mold core, on the upper surface of described lower mold core, offer the location blind hole with the corresponding cooperation of positioning through hole in upper mold core.
Described positioning through hole is circumferentially evenly arranged along the center line in upper mold core hole, answers in contrast, and described location blind hole is circumferentially evenly arranged.
The upper surface of described lower mold core exceeds linking platform.
The beneficial effects of the utility model are: core rod is arranged to split-type structural by the utility model, and upper and lower core rod can be processed respectively, greatly reduces difficulty of processing, has improved machining accuracy; In addition, because the hypomere in die sleeve hole is bellmouth, lower mold core is fitted tightly with die sleeve when mounted, very close to each other between the outer wall of lower mold core and the inwall of die sleeve, collision while effectively having avoided work between lower mold core and die sleeve, the service life of having improved die sleeve and lower mold core; In addition, only need directly the alignment pin matching with positioning through hole to be inserted in the location blind hole in positioning through hole and the lower mold core being opened in upper mold core, use very convenient, and ensured that the phase allocation between upper and lower core rod fixes, thereby further improve the quality of sintered metal product.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structure for amplifying schematic diagram of A part in Fig. 1.
Reference numeral in Fig. 1 to Fig. 2 is: 1, die sleeve, 11, be connected platform, 2, upper mold core, 20, upper mold core hole, 21, positioning through hole, 3, lower mold core, 30, lower mold core hole, 31, location blind hole, 33, outer surface, 4, upper and lower core rod step.
Detailed description of the invention
Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.
As shown in Figure 1, a kind of powder metallurgy mould described in the utility model, comprise: die sleeve 1 and be arranged on the split type core rod in die sleeve 1, this core rod comprises: upper and lower core rod 2 and 3, the outer surface of upper mold core 2 is cylinder, the outer surface 33 of lower mold core 3 is taper surface---shown in Figure 2, the hole of die sleeve 1 is divided into two sections, epimere is the cylindrical hole matching with upper mold core 2, hypomere is the bellmouth matching with lower mold core 3, is provided with and is connected platform 11 between cylindrical hole and bellmouth---shown in Figure 2; Center line along the hole of upper mold core 2 on the end face of described upper mold core 2 is provided with a pair of positioning through hole that runs through upper mold core 2 21 being circumferentially evenly arranged, and offers a pair of location blind hole 31 matching with the positioning through hole 21 in upper mold core 2 on the upper surface of described lower mold core 3.In the present embodiment, in order to ensure that the lower surface of upper mold core 2 and the upper surface of lower mold core 3 fit tightly, the upper surface of described lower mold core 3 exceeds linking platform 11.
When practical application, the hole of described upper mold core 2 is that the hole of upper mold core hole 20 and lower mold core 3 is that step between lower mold core hole 30 and upper mold core hole 20 and lower mold core hole 30 is that upper and lower core rod step 4 is corresponding with the sintered metal product that will suppress.
When installation, first lower mold core 3 and upper mold core 2 are arranged in die sleeve 1 successively, then, adopt the alignment pin matching with positioning through hole 21 to insert in the location blind hole 31 in positioning through hole 21 and the lower mold core 3 being opened in upper mold core 2.
Above-described embodiment limits the utility model never in any form, and every employing is equal to replaces or technical scheme that the mode of equivalent transformation obtains all drops in protection domain of the present utility model.
