Bubble-free metal casting machine

Abstract

The invention discloses a bubble-free metal casting machine, and relates to the technical field of metal casting. The bubble-free metal casting machine comprises a box body, a cover plate is movably installed on the top of the box body, a smelting furnace is fixedly installed on the inner side of the upper end of the box body, a movable mechanism is arranged on the inner side of the box body, a flow guide mechanism is arranged on the inner side of the box body, and a closing door is movably installed at the lower end of the front face of the box body. The movable mechanism comprises a fixed cylinder, a discharging piece and a movable piece, the fixed cylinder is arranged on the inner side of the smelting furnace, the bottom of the fixed cylinder is fixedly connected with the bottom of the inner wall of the smelting furnace, and an opening is formed in the position, close to the bottom, of the outer surface of the fixed cylinder. According to the bubble-free metal casting machine, the moving mechanism and the flow guide mechanism are arranged, airflow is guided to drive the swing part to move, so that the moving barrel is driven to move, molten metal discharged from a smelting furnace smoothly flows into the collecting part, and the situation that the molten metal is attached to the inner wall of the moving barrel, and collection of the molten metal is affected is avoided.

Description

technical field [0001] The invention relates to the technical field of metal casting, in particular to a bubble-free metal casting machine. Background technique [0002] Metal casting is the process of smelting metal into a liquid that meets certain requirements and pouring it into a mold. After cooling, solidification, and cleaning, a casting with a predetermined shape, size and performance is obtained. The casting blank is almost formed. The purpose of free machining or a small amount of machining reduces the cost and reduces the time to a certain extent. Casting is one of the basic processes of the modern machinery manufacturing industry. [0003] When the metal casting machine is in use, the metal raw materials are melted and accumulated at the bottom of the furnace, and the air at the upper end will be mixed into the molten metal during the metal melting process. When draining, it is difficult to discharge the molten metal inside smoothly, and part of the molten metal ...

Problems solved by technology

[0003] When the metal casting machine is in use, the metal raw materials are melted and accumulated at the bottom of the furnace, and the air at the upper end will be mixed into the molten metal during the metal melting process. It is difficult to discharge the molten metal inside smoothly when draining, and part of the molten metal remains in the discharge pipe, which affects the use of the metal casting machine
