Abstract
The utility model relates to the technical field of powder metallurgical molds, and in particular relates to a female die mold for powder metallurgical forming. The female die mold comprises a female die wrapping sleeve and at least three female die core blades, wherein a step hole with a wide upper part and a narrow lower part is formed in the female die wrapping sleeve; and at least three female die core blades are fixedly arranged in the step hole on the upper part of the female die wrapping sleeve and form a circle. The female die mold has a rational structure and is convenient to use; due to at least three female die core blades, the damage rate of the mold is reduced; costs of labor, time and the like are saved; stable and continuous large-batch production for high-density products can be realized; and the production efficiency is improved.
Description
Technical field
The utility model relates to the powder metallurgy die technical field, is that a kind of powder metallurgy forming is used the former mould.
Background technology
Powder metallurgy product because less or do not have that machinery processing as cutting just wait can the complicated high part of precision of production structure, so economical with materials and processing charges greatly, reduction production cost, in high volume production process, advantage is especially obvious.And the part that powder metallurgy is produced is because the existence of internal void causes the fine and close relatively part of product density lower, and in order to improve density, the board tonnage that not only moulding institute will use needs raising, and used mould also requirement will have certain ability to bear.Reach after about 7.2 and work as product density, the tension force that mould can bear requires just higher.Conventional mould is because the former core rod is in order to guarantee the precision of product; The material of high rigidity such as common employing carbide alloy; But toughness is relatively then relatively poor, and under the density conditions about 7.2, core material tends to produce breakage because having reached the limit of the power of bearing; Serious also can cause scrapping of a whole set of mould, and then influences whole production progress and efficient.
Summary of the invention
The utility model provides a kind of powder metallurgy forming to use the former mould, has overcome the deficiency of above-mentioned prior art, and it can solve high density product is prone to cause the damage of former core rod when using the former core rod problem.
The technical scheme of the utility model realizes like this: a kind of powder metallurgy forming is used the former mould; The former core rod lobe that comprises former jacket and at least three; Shoulder hole wide at the top and narrow at the bottom is arranged on the former jacket, and at least three former core rod lobe is fixedly mounted on the interior and formation circle of shoulder hole on former jacket top.
Above former core rod lobe is four.
Above former core rod lobe is a hard alloy steel former core rod lobe.
Above former jacket is a steel former jacket.
The utility model is rational in infrastructure; Easy to use, through at least three former core rod lobes are installed the damaged probability of mould is reduced, practiced thrift costs such as manpower and time; Make high density product also can realize the stable production in enormous quantities that continues, production efficiency is improved.
Description of drawings
Fig. 1 looks sectional structure chart for the master of the utility model.
Fig. 2 is that the A-A of Fig. 1 is to the sectional structure sketch map.
Coding among the figure is respectively: 1 is the former jacket, and 2 is former core rod lobe, and 3 is shoulder hole.
The specific embodiment
Like Fig. 1 and shown in Figure 2; A kind of powder metallurgy forming is used the former mould; Comprise former jacket 1 and at least three s' former core rod lobe 2, shoulder hole wide at the top and narrow at the bottom 3 is arranged on former jacket 1, at least three former core rod lobe 2 is fixedly mounted in the shoulder hole on former jacket 1 top and forms circular.In process of production, upper and lower mould dashes and exerts pressure through board, the product compacting is reached the density requirements of design; At this moment; Part produces outside tension force because be squeezed the generation plastic deformation to former jacket 1 and former core rod lobe 2, and former core rod lobe 2 is because be divided into 3 to 4 lobes in manufacturing process; Suffered tension force own is directly delivered on the former jacket 1, and former jacket 1 is because the high generation of toughness elastic deformation; When upper and lower mould dashes pressure is discharged, after product was deviate from former, tension force disappeared, and former jacket 1 is because elastic recoil restores to the original state.Convert strain into thereby reach the tension force that mould is born, and can make the precision of product can guaranteed purpose.
Like Fig. 1 and shown in Figure 2, former core rod lobe 2 is four, and is stressed so relatively more balanced; As required, former core rod lobe 2 is a hard alloy steel former core rod lobe, and former jacket 1 is specially 45# steel former jacket for for steel former jacket.
