Continuous cast extrusion molding device

Abstract

The invention discloses a continuous cast extrusion molding device. The continuous cast extrusion molding device is capable of dissipating heat sufficiently and enables metal grains to rub sufficiently. The continuous cast extrusion molding device comprises a rack, cast extrusion wheels and a cast extrusion boot base are movably arranged on the rack, annular cast extrusion grooves are formed in the cast extrusion wheels, and arc cast extrusion grooves matched with the annular cast extrusion grooves are arranged on the cast extrusion boot, a stopping block and a discharging mold which are matched with the annular cast extrusion grooves are arranged on the cast extrusion shoe plate, and the center of the section, corresponding to the center lines of a discharging mode hole and the annular cast extrusion grooves and the center of the section, corresponding to the center lines of the discharging mode hole and the arc cast extrusion grooves are located at the center line of the discharging mode hole. A diversion groove communicated with the arc cast extrusion groove is formed in the upper end of the arc cast extrusion groove, heat conduction holes communicated with the diversion groove are formed in the cast extrusion boot, and heat emission hole corresponding to the heat conduction holes one by one is formed in the cast extrusion boot base. The continuous cast extrusion molding device is used for manufacturing aluminium rods with high quality.

Description

technical field [0001] The invention relates to the field of metal material processing, in particular to a device for continuously casting and extruding metal in a hot melt state to finally form a rod. Background technique [0002] At present, the traditional continuous casting extrusion molding device only has casting extrusion grooves on the casting extrusion wheel, and there is no casting extrusion groove on the casting extrusion shoe. Since the casting extrusion wheel is rotating, the various casting extrusion grooves on the casting extrusion wheel are determined. The depth of the place is consistent, which determines that the flow channel between the casting wheel and the casting shoe does not change, so that the friction between the grains of the metal in the hot melt state is not sufficient in the flow channel, thus affecting the bar. quality. In addition, since the hot gas formed during the cooling process of the metal in the hot melt state cannot be dissipated quic...

Problems solved by technology

[0002] At present, the traditional continuous casting extrusion molding device only has casting extrusion grooves on the casting extrusion wheel, and there is no casting extrusion groove on the casting extrusion shoe. Since the casting extrusion wheel is rotating, it determines the various casting extrusion grooves on the casting extrusion wheel. The depth of the spot is consistent, which determines that the flow channel between the casting wheel and the casting shoe does not change, so that the friction between the grains of the metal in the hot melt state is not sufficient in the flow channel, thus affecting the bar. quality

In addition, since the hot gas formed during the cooling process of the metal in the hot melt state cannot be dissipated quickly at the opening of the runner, a small amount of air bubbles remain in the formed rod, which affects the quality of the rod
