Abstract

A die holding frame for the die press of powder is composed of punch die and its jointer, the upper, external lower, medium lower and internal lower formworks, female and its holder, guide columns, three coaxial annular cylinders, and three annular drive rods associated with said three coaxial annular cylinders. Its advantages are synchronous drive to said formworks, and high quality of workpiece.

Description

Technical field [0001] The invention relates to powder metallurgy equipment, in particular to a mold base for a powder compacting machine. Background technique [0002] Powder metallurgy is the process and technology of manufacturing metal powder and using metal powder as the basic raw material to manufacture metal materials and special-shaped products. The mold base is an indispensable process equipment for manufacturing powder metallurgy products. In order to improve the performance of the mold base, a multi-layer template powder press molding mold base is disclosed in the Chinese invention patent No. 03139803.0, although this type of mold base is equipped with multiple table powder metallurgy parts of different types and shapes. However, this kind of mold base has the following problems: (1) Because of the use of integrated oil cylinders, each template needs to be driven by 4 oil cylinders. Therefore, during the movement of the template, the problem that t...
