Problems solved by technology

[0002] At present, the production process of quartz crucibles for pulling single crystals is to mold quartz sand into graphite molds and then make quartz crucibles by arc melting. The process of molding quartz sand into graphite molds is manual feeding. Feeding cannot accurately control the layer thickness and weight of the raw material formed on the inner wall of the graphite mold, the operation is cumbersome and may contaminate the quartz sand raw material

Abstract

The invention discloses a quartz crucible forming device which is characterized by comprising a rotating platform, a graphite die, a forming die, a water cooling die and a feed opening, wherein the water cooling die is sleeved on the outer wall of the graphite die; the forming die is fixed inside the graphite die and is spaced from the graphite die for a certain gap with the length equal to the thickness of the quartz crucible; the forming die is made of a quartz product or stainless steel product and can rotate; the feed opening is fixed above the graphite die and aligns to the gap between the graphite die and the forming die. Compared with the prior art, the quartz crucible forming device is simple, convenient and precise; in addition, artificial feeding is replaced with automatic forming, so that the thickness and weight of the formed quartz sand raw material are controlled, artificial errors are reduced, and the forming precision of the quartz sand on the inner wall of the graphite die is ensured.

Description

technical field [0001] The invention mainly relates to production equipment for quartz crucibles, in particular to feeding and forming equipment for preparing quartz crucibles for pulling single crystals. Background technique [0002] At present, the production process of quartz crucibles for pulling single crystals is to mold quartz sand into graphite molds and then make quartz crucibles by arc melting. The process of molding quartz sand into graphite molds is manual feeding. Feeding cannot accurately control the layer thickness and weight of the raw material formed on the inner wall of the graphite mold, the operation is cumbersome and may contaminate the quartz sand raw material. [0003] The present invention is an improvement to the existing molding method, which replaces manual feeding with automatic molding, controls the thickness and weight of the molding quartz sand raw material, reduces manual errors, and ensures the molding accuracy of the quartz sand on the inner...
