Mold supporting mechanism

Abstract

The invention belongs to the technical field of ceramic production and processing, and particularly relates to a mold supporting mechanism. The mold supporting mechanism comprises a mold and supporting blocks arranged at intervals along the circumferential direction of the mold; the mold comprises an annular mold sleeve and a bottom plate, wherein the annular mold sleeve and the bottom plate are made of elastic materials; the annular mold sleeve is provided with a narrowed-down structure, the annular surface of the mold sleeve corresponding to the waist-shaped structure is equally divided intoat least two independent arc surfaces along the circumferential direction, the adjacent arc surfaces are connected into a whole through rib plates, the rib plates are of a hinge-shaped structure, thetwo hinge surfaces of the rib plates are correspondingly connected with adjacent edges of the two adjacent arc surfaces into a whole, and the hinges protrude out of the outer ring surface of the annular mold sleeve; and fan-shaped areas between the supporting blocks and every two adjacent rib plates of the mold are arranged in a one-to-one correspondence manner, and the supporting blocks are movably arranged in a reciprocating manner along the radial direction of the mold. The supporting mechanism can support arc-shaped surfaces and the rib plates of the waist part of the mold, so that a gapcaused by vibration between each arc-shaped surface and the rib plates during feeding is prevented, so that burrs on the peripheral surface of a blank body are avoided.

Description

technical field [0001] The invention belongs to the technical field of ceramic production and processing, and in particular relates to a mold supporting mechanism. Background technique [0002] Isostatic pressing is to place the object to be processed in a closed container filled with liquid, and gradually pressurize through the pressurization system to apply equal pressure to each surface of the object, so that the molecules can be reduced without changing the appearance shape. The distance between them 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.

For this reason, the inventor of the present invention relates to a kind of brand-new ceramic isostatic pressing molding mold, and this mold has the mold cavity of one-piece type, no matter it is to all have significant improvement in molding quality and molding efficiency, but the periphery of the mold cavity There are gaps, and the existing filling method is easy to make the ceramic material enter the gap, thus affecting the molding quality of the green body
