DEVICE FOR PRESSING POWDER MATERIALS OF ELECTRONIC ENGINEERING ARTICLES Russian patent published in 2016 - IPC B22F3/02 B30B7/02 

FIELD: electronics.

SUBSTANCE: invention relates to pressing electronic engineering articles from a powder material. Device contains a press base located horizontally, a bottom male die with its base arranged on the horizontal surface of the press base and a top male die, a female die with closed working cavity. Top and bottom male dies are made as rectangular parallelepipeds. Female die consists of four parts, two of which are made as halves of a hollow truncated cone and are arranged at a distance from the horizontal surface of the press base, herewith the cross section in horizontal plane of the inner surface of each of the two halves is an isosceles trapezoid with a smaller base equal to the male die base, and two other parts of the female die are located inside along the ends of the said two parts of the female die in the form of halves of the hollow truncated cone and are made as straight triangular prisms. Female die on the outer side is equipped with a clamping ring, inner surface of which repeats its outer surface, and on the inner side each of the two parts of the female die representing halves of the hollow truncated cone is equipped with an elastic deformation insert in the form of a rectangular parallelepiped.

EFFECT: higher quality of pressing is ensured.
