| Abstract: | According to the theory of fluid mechanics,the flow shape of extrusion cavity die was designed,which was key part of ceramic slurry microflow extrusion forming process.Using ANSYS software,the flow velocity of extrusion cavity die export cross section and the distribution of pressure within the flow field were simulated.The internal pressure field and outlet flow velocity distribution of four different flow shape extrusion cavity dies were analyzed.The research provides the theoretical basis to solve the difficult problem of ceramic paste extrusion forming process and has a important reference value. |
