Basic Principles of Powder Metallurgy Mold

Oct 07, 2017


Due to the powder pressing method, the powder pressing mold is also varied. According to the press method can be divided into different: pressing die, fine mold, complex die, forging mold, and so on.

The basic principle of powder metallurgy mold design is: give full play to the powder metallurgy less, no cutting and forming the process characteristics, to ensure that the blank to achieve the geometric shape and size, accuracy and surface roughness, density and distribution of three basic requirements , Whether it is pressing die, fine mold, complex die, forging die are required so. Among them, the density and distribution of the billet and forging billet are the main technical indexes in the mold design. The mold structure and the mold material are designed rationally so that the mold parts have high strength, stiffness and hardness, Wear resistance and service life to meet the safety and reliability of high-pressure working containers and easy to operate the requirements.


At the same time pay attention to the mold structure and mold parts of the workability and interchangeability, and reduce the mold manufacturing costs. The design steps and basic methods are as follows: First understand and master the design information, as an important basis for mold design; followed by product requirements for material design and process design, according to product drawings for blank design or preform design, and select Presses and pressing methods, design mold structure sketch; and then to blank size as the basic basis, taking into account the size of the process changes, respectively, the main mold parts size, generally calculated directly related to the cavity size, and then in accordance with the mold Assembly relationship calculation of other mold parts size; Finally drawing mold assembly drawings and parts drawings, according to various types of molds different work requirements, dimension size deviation and shape and position tolerance, and select the mold material and technical requirements.
