The piezoelectric ceramic extrusion forming device can solve the problems that piezoelectric ceramics cannot be extruded into different sizes in the existing piezoelectric ceramic extrusion molding process, the piezoelectric ceramics are difficult to take downfrom a die after being extruded, the piezoelectric ceramic double-sided extrusion operation is complex and the like, the piezoelectric ceramics can be laid on a thin film, and the piezoelectric ceramics are extruded into the functions of different sizes.

Description

technical field [0001] The invention relates to the technical field of ceramic materials, in particular to a composite biological piezoelectric ceramic forming device and a forming method thereof. Background technique [0002] Piezoelectric ceramics are information functional ceramic materials that can convert mechanical energy and electrical energy into each other. In addition to piezoelectricity, piezoelectric ceramics also have dielectric properties, elasticity, etc., and have been widely used in medical imaging, acoustic sensors, acoustic Transducers, ultrasonic motors and other fields; bio-piezoelectric ceramics refer to piezoelectric ceramic materials used as biomedical materials. [0003] The production process of piezoelectric ceramics is as follows. The ingredients are mixed and ground, pre-fired, and the second grinding and granulation is formed. The plastic is sintered and sintered into porcelain. The shape is processed and tested by electrode high-voltage polariz...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the above problems, the present invention provides a composite bio-piezoelectric ceramic molding device and its molding method, which can solve the existing piezoelectric ceramic extrusion molding cannot extrude piezoelectric ceramics into different sizes, piezoelectric ceramics It is difficult to remove from the mold after extrusion, and the double-sided extrusion operation of piezoelectric ceramics is cumbersome.
