Abstract
The utility model discloses a die for manufacturing a high-purity corundum crucible. The die comprises a bottom die (1), an outer die (2) and an inner die (3). The bottom of the outer die (2) is fixed to the bottom die (1), the inner die (3) is located in an inner cavity of the outer die (2), and a cavity between the inner die (3) and the bottom die (1) and a cavity between the inner die (3) and the outer die (2) form a casting die (4) of the high-purity corundum crucible. The die is characterized in that the inner die (3) comprises an inner die tube (31) and a bottom cover (32), a through hole is formed in the bottom wall of the inner die tube (31), the lower portion of the bottom cover (32) is inserted into the through hole of the bottom wall of the inner die tube (31), and the bottom cover (32) is fixed to the bottom wall of the inner die tube (31). As the inner die is divided into the inner die tube and the bottom cover, and a detachable mode is adopted for the bottom cover and the inner die tube, the problem that the bottom of the high-purity corundum crucible is difficult to strip from the die due to suction is solved, and the die is suitable for manufacturing various large crucibles.
Description
Technical field
The utility model relates to the high-purity corundum crucible of the surface metalation processing of smelting, hot investment casting and the product of various non-ferrous metals, and when specifically a kind of integrated poured moulding the demoulding of solution bottom, high-purity corundum crucible is because of the air-breathing mould for the preparation of high-purity corundum crucible that is difficult to the demoulding.
Background technology
High-purity corundum crucible is for the smelting of various non-ferrous metals, hot investment casting, and the key equipment of the surface metalation processing of product.High-purity corundum crucible is to replace former non-ferrous metal molten bath of building by laying bricks or stones with corundum brick, is characterized in that consumptive material is few, it is low to consume energy, cost is low and long service life.High-purity corundum crucible has in use solved and has become while causing greatly the problems such as molten bath perforation, existing high-purity corundum crucible die to be difficult in use solve the bottom demoulding product because of the air-breathing problem that is difficult to the demoulding because of former corundum brick brickwork joint melting loss.
Summary of the invention
The purpose of this utility model is that while being difficult in use solve the bottom demoulding for existing high-purity corundum crucible die, product is because of the air-breathing problem that is difficult to the demoulding, and when a kind of integrated poured moulding being provided and solving the bottom demoulding, high-purity corundum crucible is because of the air-breathing mould for the preparation of high-purity corundum crucible that is difficult to the demoulding.
The purpose of this utility model solves by the following technical programs:
A kind of mould for the preparation of high-purity corundum crucible, comprise bed die, external mold and internal mold, the bottom of external mold is fixed on bed die, internal mold is arranged in the inner chamber of external mold, cavity between internal mold and bed die and external mold forms the chamber of building of high-purity corundum crucible, it is characterized in that described internal mold comprises internal mold mould cylinder and bottom, the diapire of internal mold mould cylinder is provided with through hole, and the bottom of bottom embeds in the through hole of internal mold mould cylinder diapire and bottom is fixed on the diapire of internal mold die wall by connector.
Described bottom embeds the long-pending sectional area that is less than bottom and is positioned at internal mold mould cylinder diapire upper portion of partial cross section in the through hole of internal mold mould cylinder diapire.
The bottom of described bottom is mutually concordant with the bottom of internal mold mould cylinder diapire.
Described bottom is bolted on the diapire of internal mold die wall.
Top and the fixed cross beam of described internal mold are fixedly linked, and fixed cross beam is arranged on the top of external mold.
The utility model has the following advantages compared to existing technology:
The utility model is by being divided into internal mold internal mold mould cylinder and bottom, and adopt dismountable mode between bottom and internal mold mould cylinder, while having solved the demoulding of high-purity corundum crucible bottom because of the air-breathing problem that is difficult to the demoulding, and this high-purity corundum crucible is integrated poured moulding, is applicable to the preparation of various large-scale crucibles.
