Abstract

The invention discloses a powder molding device and a molding method thereof. The device comprises a mold, a pair of yokes meshed on the outer side of the mold, coils wound on the outer sides of the yokes, a mold cavity formed in the middle portion of the mold, straight strip yokes vertically embedded on the outer side of the mold cavity, an upper mold movably embedded on the upper side of the mold cavity, a lower mold movably embedded on the lower side of the mold cavity and a vibration mechanism mounted in cooperation with the bottom of the lower mold; the vibration mechanism is mounted on the top plate; hollow sliding rods are further mounted on the top plate, and the hollow sliding rods and the mold are movably embedded; and a pressing plate is mounted on the top of the upper mold in a matched manner. The molding method of the powder molding device comprises the following steps of firstly, operation before filling, secondly, preliminary material filling, thirdly, material filling again, fourthly, mold assembly direction selection, fifthly, molding and sixthly, mold stripping. According to the powder molding device and the molding method of the device, the direction selection precision can be improved, and the yield and the product quality are improved.

Description

technical field [0001] The invention relates to a powder forming mechanism, in particular to a powder forming device and a forming method thereof, belonging to the technical field of powder forming. Background technique [0002] The process of compacting the metal powder body into a compact with a certain shape, size, density and strength; it is one of the basic processes of the powder metallurgy process; before the powder is formed, the metal powder is generally powder pretreated to meet the forming requirements When mixing materials, generally a certain amount of powder forming additives must be added; powder forming is divided into two categories: powder pressing forming and powder special forming; Forming method; at the end of the 18th century and the beginning of the 19th century, Russia and the United Kingdom used steel molds to press and manufacture platinum products; subsequently, the powder pressing and forming method was gradually improved, and was used to press va...
