Problems solved by technology

1) In order to be easy to hold, the suction pipe section of the tee pipe should not be too long, so when processing a deep cavity, it is necessary to add a straight tube, which is inconvenient to manage; 2) For castings with complex structures with tortuous cavities, it is difficult for operators to see Whether the gravel in the "dead corner" area with dim light is effectively removed; 3) The gravel sucked out of the cavity is directly discharged into the air, causing pollution

Abstract

The invention discloses a three-way pipe for casting and a use method thereof. The three-way pipe for casting comprises an air feeding pipe and an air discharging pipe which are connected; an air suction pipe communicating with the air feeding pipe is installed on the air feeding pipe, a pneumatic flexible pipe is connected to one end of the air feeding pipe, and the air discharging pipe is connected to the other end of the air feeding pipe; and the pneumatic flexible pipe is connected with a compressed air leather pipe through a glass steel pipe. According to the three-way pipe for casting and the use method thereof, effective removing for foreign matter such as cavity gravel can be achieved, working air strength is effectively ensured, a coating layer of a sand mold is prevented from being destroyed, and the labor strength is lowered; and meanwhile, by using the aerodynamics principle, a self-made miniature electric generator is additionally installed so that power supply for a highlight torch can be achieved.

Description

technical field [0001] The invention relates to a tee pipe for casting and a using method thereof, which is especially suitable for sand casting production and belongs to the technical field of casting. Background technique [0002] In sand casting production, the cleanliness of the cavity inside the sand mold has a very critical impact on obtaining castings with stable quality. For the open sand mold cavity, the effect of cleaning can be achieved only by repeatedly blowing the cavity with a compressed air tube. However, in actual production, most of the cavities are complex and tortuous shapes, and the compressed air pipe cannot blow out debris such as gravel, and needs to rely on negative pressure to absorb debris. [0003] Practice shows that the tee pipe of the prior art has the following disadvantages. 1) In order to be easy to hold, the suction pipe section of the tee should not be too long, so it is necessary to add a straight tube when processing a deep cavity, whi...
