Definitions

  • the utility model relates to the field of powder metallurgy molding, in particular to a planetary powder metallurgy forming mold.
  • Powder metallurgy is a process technology for producing metal materials, composite materials, and various types of articles by forming metal powder or using metal powder (or a mixture of metal powder and non-metal powder) as a raw material, and forming and sintering.
  • the powder metallurgy method has similarities with the production of ceramics, and all belong to the powder sintering technology. Therefore, a series of new powder metallurgy technologies can also be used for the preparation of ceramic materials. Due to the advantages of powder metallurgy technology, it has become the key to solving new material problems and plays a decisive role in the development of new materials.
  • the planet carrier is in a mold that is formed by powder metallurgy. Due to the morphological characteristics of the planet carrier, two of the punch metal molds in the planetary metallurgy mold are in a one-piece structure, but due to the problem of the amount of metal powder added, the integrated type The punch is prone to breakage during die casting.
  • the technical problem to be solved by the utility model is to provide a planetary powder metallurgy forming mold; and to solve the problem that the integrated planetary frame powder metallurgy forming mold is prone to breakage during the formation of the planetary frame due to the addition amount of the powder.
  • the technical solution of the present invention is: a planetary frame powder metallurgy forming mold, comprising a first mold, a second mold, a third mold and a total mold base; the innovation is: the first mold The second mold and the third mold are supported by separate mold bases;
  • the main mold base is provided with a model hole for accommodating the first mold, the second mold and the third mold, and a groove for accommodating the respective mold base; the first mold, the second mold and the third mold pass through the total

Abstract

L'invention concerne un moule de formation pour métallurgie des poudres à bâti planétaire, lequel moule comprend un premier moule (1), un deuxième moule (2), un troisième moule (3), et une base de moule globale (4). Le premier moule (1), le deuxième moule (2) et le troisième moule (3) sont supportés par des bases de moule individuelles de chacun d'entre eux. Les moules sont adaptés et montés sur la base de moule globale (4) par l'intermédiaire des bases de moule individuelles, l'emploi d'une structure intégrée de moules et d'une base de montage est évitée, de façon à éviter ainsi, lors de l'ajout d'une poudre métallique, à une quantité excessive ou insuffisante de la poudre métallique d'être ajoutée du fait du problème avec une structure de moule intégrée, et à éviter ainsi la génération de fissures sur un bâti planétaire quand un poinçon moule sous pression un métal en poudre.
