Internal heating die sleeve

Abstract

The invention discloses a die sleeve and particular relates to an internal heating die sleeve for producing an anode and a cathode by a vibration molding method. The structure of the die sleeve is that: a partition plate (5), a support plate (3) with a hole (9), an upper cover plate (8) and a lower cover plate (11) are arranged between a die sleeve outer wall (1) and a die sleeve inner wall (2); the die sleeve outer wall (1), the die sleeve inner wall (2), the upper cover plate (8) and the lower cover plate (11) form a closed cavity; the die sleeve outer wall (1) is provided with a heat source inlet (4) and a heat source outlet (6); and the partition plate (5) is arranged at a position between the heat source inlet (4) and the heat source outlet (6) and connected with the upper cover plate (8) and the lower cover plate (11). The die sleeve has the advantages of simple structure, safe and convenient use and low cost. The die sleeve has a relatively high temperature during carbon block molding and demolding is successful after molding, so that the outer surface quality of a carbon bock is improved.

Description

technical field [0001] The invention relates to a die set, in particular to an internal heating die set suitable for producing anodes and cathodes by a vibration forming method. Background technique [0002] Most of the anode and cathode carbon blocks used in the production of electrolytic aluminum are produced by vibration molding machines, and the mold sleeve is one of the important parts of the vibration molding machine. In the past, the insulation material of mold sleeves generally used silicon aluminum acid-resistant fiber. Under the strong vibration of high frequency, its thermal insulation performance will gradually decrease, and the thermal insulation material is installed between the inner wall and the outer wall of the mold sleeve and cannot be replaced, which requires the replacement of the mold sleeve, resulting in waste. In addition, because the temperature of the inner wall of the mold cover is lower than the temperature of the outer surface of the carbon block...

Problems solved by technology

[0002] Most of the anode and cathode carbon blocks used in the production of electrolytic aluminum are produced by vibration molding machines, and the mold sleeve is one of the important parts of the vibration molding machine. In the past, the insulation material of mold sleeves generally used silicon aluminum acid-resistant fiber. Under high-frequency strong vibration, its thermal insulation performance will gradually decrease, and the thermal insulation material is installed between the inner wall and the outer wall of the mold sleeve and cannot be replaced, which requires the replacement of the mold sleeve, resulting in waste

In addition, because the temperature of the inner wall of the mold sleeve is lower than the temperature of the outer surface of the carbon block, it is difficult to demould, which damages the quality of the outer surface of the carbon block during demoulding.
