Porcelain Blank Forming System

Abstract

The invention belongs to the technical field of ceramic production and machining and particularly relates to a ceramic blank forming system. The ceramic blank forming system comprises a die, a die conveying device, a padding device, a pressurizing device and a die releasing device, wherein the padding device, the pressurizing device and the die releasing device are arranged in sequence in the conveying direction of the die conveying device. The die comprises a ring-shaped die sleeve made of an elastic material, a top plate and a bottom plate, wherein the top plate and the bottom plate are located at the upper end and the lower end of the ring-shaped die sleeve correspondingly. The ring-shaped die sleeve is provided with a waist-shaped structure, a die sleeve ring face corresponding to thewaist-shaped structure is equally divided into at least two independent arc faces in the circumferential direction, every two adjacent arc faces are integrally connected through a rib plate, the rib plates are of hinge-shaped structures, two hinge faces of each rib plate are integrally connected with the adjacent edges of the adjacent two arc faces, and the hinges protrude on the outer ring face of the ring-shaped die sleeve. By means of the ceramic blank forming system, due to the padding device, the pressurizing device and the die releasing device, automatic forming of ceramic blank bodies is achieved, the production and machining efficiency is greatly improved, and the labor cost is saved.

Description

technical field [0001] The invention belongs to the technical field of ceramic production and processing, and in particular relates to a porcelain blank forming system. Background technique [0002] The isostatic pressing process is to place the object to be processed in a closed container filled with fluid medium, and gradually pressurize through the booster system to apply equal pressure to each surface of the object, so that it does not change the appearance shape. Reducing the distance between molecules increases the density and improves the physical properties of the substance. Nowadays, isostatic pressing technology has been widely used in the field of ceramic processing. Different from traditional ceramic processing technology, isostatic pressing ceramic processing technology usually uses dry powder as the raw material for processing. Ceramic dry powder is processed by ball milling and granulation in the early stage. After being extruded, it can be well bonded as one...

AI Technical Summary

Problems solved by technology

In the isostatic pressing process, the quality of the mold directly affects the quality of the molded workpiece. However, for some objects with special structures, there are still many defects in the mold design in the prior art, for example, for figure 1 When the object with obvious waist-like structure shown in the figure is isostatically pressed, in order to facilitate demoulding, the mold is generally set symmetrically in two halves, and the mold with two halves has a relatively fast mold closing and mold opening process. It is cumbersome. On the other hand, it will leave obvious lines on the surface of the object, which will affect the appearance quality. In addition, isostatic pressing molds are generally made of elastic materials. Two-half molds are not conducive to shape retention when filling.

The ceramic isostatic pressing molding process in the prior art generally requires a large number of manual auxiliary operations, and the processing efficiency is low
