Description

Technical Field

[0001] The utility model relates to the technical field of crucible production, in particular to a crucible blank hoisting device. Background Art

[0002] A crucible is a cup-shaped vessel used in the laboratory to heat solids at high temperatures. There are two main methods for forming a crucible: extrusion molding and injection molding. Extrusion molding is to extrude quartz powder through an extruder to form the shape and size of the crucible. Injection molding is to mix quartz powder with an organic binder and inject it into a mold to form it. After the crucible blank is formed, it needs to be sent to a high-temperature furnace for baking and shaping.

[0003] Currently, when hoisting a crucible blank, an internal support method or a clamping method is often used for hoisting and fixing. Both of the above methods have the risk of causing damage to the crucible blank when a large force is applied, and are therefore not very practical. Utility Model Content
