Zirconium oxide ceramic injection molding device and control method thereof

Abstract

The invention discloses a zirconium oxide ceramic injection molding device and a control method thereof. The device comprises a supporting seat, wherein a material injection box is fixedly connected to the top of one side of the supporting seat; a hopper is inserted into the top of the material injection box, and heating plates are arranged on the inner walls of the two sides of the material injection box; a first motor is arranged in the material injection box, the output end of the first motor is fixedly connected with a rotating shaft, and a plurality of stirring rods are fixedly connectedto the rotating shaft; and one side of the material injection box is provided with a feeding pipe, one end, far away from the material injection box, of the feeding pipe is provided with a feeding head, and the feeding pipe is provided with a control valve. According to the device and the control method, a prepared material is heated and stirred through a stirring mechanism, so that the prepared material is heated and diluted to increase the injection pressure quality; and an injection molding module is conveniently switched back and forth between material injection and injection molding through the design of a rotatable module, so that the loss of the heat quantity of the prepared material during injection molding is effectively reduced, uniform injection of the material is ensured, and the efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of zirconia ceramics, in particular to a zirconia ceramic injection molding device and a control method. Background technique [0002] Zirconia ceramics have excellent properties such as high melting point and boiling point, high hardness, insulator at room temperature, and electrical conductivity at high temperature, so they are widely used in the field of structural ceramics. The manufacturing process of zirconia ceramics consists of multiple processes. Among them, ceramic molding is one of the important processes of ceramic manufacturing. The molding of zirconia ceramics includes dry pressing molding, isostatic pressing molding, grouting molding, hot die casting molding, tape casting molding, injection molding, plastic extrusion molding, and colloidal solidification. molding etc. [0003] The existing injection molding device for zirconia ceramics has low portability. It is necessary to inject the mold i...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to solve the problem that the portability of the zirconia ceramic injection molding device is low, and it is necessary to inject the mold into the mold during injection and then move it to a different station for injection processing. , resulting in problems such as easy cooling of the prepared material during injection pressure, uneven injection, and low production efficiency
