Self-priming soup dispenser

Abstract

The invention relates to a self-suction fluid feeder. The self-suction fluid feeder comprises a suction pouring device and a transfer device for driving the suction pouring device to move. The suction pouring device comprises a pouring tank and a blocking assembly. A pouring cavity for containing molten metal is formed in the pouring tank. The lower end of the pouring tank is provided with a suction pouring hole communicating with the pouring cavity. The pouring cavity is provided with exhaust ducts communicating with the outside. The blocking assembly comprises a blocking head used for opening and closing the suction pouring hole. The self-suction fluid feed is provided for effectively reducing the oxide content of poured molten metal and improving the casting quality. The self-suction fluid feeder has the advantages that suction pouring of molten metal is conducted through cooperation of the pouring tank and the blocking assembly; the pouring tank is inserted into molten metal to conduct automatic suction; an oxide skin on the surface layer of the molten metal is prevented from being sucked into the pouring cavity, and quantitative transfer of the molten metal can be realized by controlling the insertion depth of the pouring tank.

Description

technical field [0001] The invention relates to the field of casting, in particular to a self-priming soup dispenser. Background technique [0002] Metal die-casting technology is widely used in various industries. In the foundry industry, automatic pouring equipment has been used to replace manual pouring and feeding methods. [0003] The existing automatic soup feeding equipment is driven by a motor, and the operation mode of digging soup and pouring soup with a soup ladle is used. Due to the direct contact between the molten metal and the air, the high-temperature molten metal reacts with oxygen to form oxide skin and adheres to the molten metal. On the surface, the oxide skin will be scooped away when the soup ladle digs the soup, and the molten metal with oxide skin is cast into shape, and the oxide skin exists in the casting body, which will have a negative impact on the performance of the casting; [0004] In addition, during the process of scooping the molten metal ...

[0003] The existing automatic soup feeding equipment is driven by a motor, and the operation mode of digging soup and pouring soup with a soup ladle is used. Due to the direct contact between the molten metal and the air, the high-temperature molten metal reacts with oxygen to form oxide skin and adheres to the molten metal. On the surface, the oxide skin will be scooped away when the soup ladle digs the soup, and the molten metal with the oxide skin will be cast into shape. The oxide skin exists in the casting body, which will have a negative impact on the performance of the casting;

[0004] In addition, during the process of scooping up the molten metal from the holding furnace to pouring the mold, the automatic soup feeding equipment has a long movement stroke, and the molten metal on the soup ladle is in contact with the air for a long time, which is easy to form secondary oxidation
