One-time forming mold for graphite crucible

Abstract

The invention relates to a one-step forming die of a graphite crucible. The one-step forming die comprises a die body, movable front doors and opening and closing door cylinders, wherein the movable front doors cover the right end of the die body in a sealing manner; the piston rods of the opening and closing door cylinders are connected with the movable front doors; the die body comprises an outer pipe body and an inner core body; the outer pipe body adopts a hollow structure with two end openings; the inner core body is placed in the outer pipe body; a flow channel is formed among the outer pipe body, the inner core body and the movable front doors. The one-step forming die for the graphite crucible has the characteristics that 1, the manufactured crucible is high in density, great in strength and uniform in texture; 2, the rejection rate is low, and the production cost is low; 3, the operation is simple, and the manpower is saved; 4, the crucible body can be freely controlled according to requirements; 5, the crucible body and the crucible bottom can be formed at one step, and the overall crucible body is uniform in density.

Description

technical field [0001] The invention relates to the technical field of graphite crucible manufacture, in particular to a graphite crucible primary forming mold. Background technique [0002] For a long time, the molding of graphite crucible is mainly made by vibration molding and graphite electrode digging, but the products produced by vibration molding process have low and uneven volume density, and cracks are easy to occur during the roasting process, and the length of the crucible is limited by the size of the mold ; The cost of the graphite crucible made of graphite electrode is high, the processing process is loaded down with trivial details and the damage rate is high. [0003] Therefore, the prior art needs to be improved and improved. Contents of the invention [0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a graphite crucible one-time forming mold, the graphite crucible produced by it is not only high in de...
