Embodiment Construction

[0066] as from figure 1 As can be seen in FIG. 2 , the container pressing device 10 shown by way of example is used as a pressing device for isostatic pressing of extruded parts, in particular cup-shaped containers 11 or hollow bodies. The container 11 shown by way of example comprises an essentially hollow body or cup section 12 and a lateral projection, in particular a handle 13 , located thereon. The exemplary handle 13 is connected to the cup section 12 via an upper and a lower collar projection or handle projection 14 . The container extrusion device 10 is designed such that a container 11 with cup section 12 and handle 13 can be extruded from powdered and / or granular extrusion material in a single extrusion process.

[0067] The container extrusion device 10 has, in particular, an upper die receptacle 15 and, in particular, a lower die receptacle 16 , between which the actual extrusion die 20 can be clamped. Powdered and / or granular, in particular ceramic, extrusion ma...

Abstract

The invention relates to a method and an in particular container press arrangement (10) for pressing a pressed part, in particular a container (11) having at least one handle (13) made from a powdered and/or granulated ceramic material to be pressed (18). The press arrangement has a first compression mould component (22), which has a membrane (26) at which compression pressure (p1) can be applied on the back side, an outer mould (40) which is elastic at least in sections, and which is inserted or can be inserted in the first compression mould component (22), and a second compression mould component (23; 60) which can be arranged as a counter element for forming a moulding cavity (43) between itself on the one side and an interior mould section, in particular a cup moulding section (50) of the outer mould (40), on the other side. In addition, an outer mould of this type, a method, and a device for the production of the same are also provided.

Description

technical field [0001] The invention relates to an extrusion device (in particular a container extrusion device) for extruding extruded parts, in particular containers with handles, from powder and / or granular ceramic extrusion material, and the invention relates to A method for extruding such extruded parts from powder and / or granular ceramic extrusion material. Background technique [0002] Such methods and extrusion tools for the isostatic pressing of powdered and / or granular ceramic extrusion materials generally have an extrusion tool with two die parts. In the assembled state, the two die parts form a forming space between them. On the side facing the forming space, the stamping parts each have a membrane which can be acted upon on the underside by the pressure as pressing pressure. The extruded material filled into the forming space is compressed into an extruded or formed part by means of the membrane or by the pressing pressure acting on the underside via the membr...
