Mold Apparatus for Powder Injection Molding for fabricating Piezoelectric Composition

摘要

The present invention solves the problem that a molded product is stuck or twisted in a mold without using a milipine when a molded product is taken out from the mold during molding of a 1-3-type or a 2-2-type piezoelectric composite by powder injection molding, The present invention relates to a mold apparatus for powder injection molding for producing a piezo-electric composite, in which a cavity corresponding to the shape of the molded article is formed in a mold apparatus for producing a molded article in which one or more columns are arranged on a plate The mold body includes a first body part forming a first cavity part having a shape corresponding to one side of the column, And a second body portion forming a second cavity portion having a shape corresponding to the other side of the column, wherein at least one of the first body portion and the second body portion is operable from the other fixed body.
