Casting and forming system of tin bar

Abstract

The invention discloses a casting and forming system of a tin bar. The casting and forming system comprises a tin liquid storage cylinder, a tin liquid constant flow cylinder, a first conveying pipeline, a reflux pipeline, a second conveying pipeline, an anti-oxidation part, a cooling mold and a shunting circular plate, wherein a tin liquid reflux hole and a tin liquid outflow hole are formed in the tin liquid constant flow cylinder, and the tin liquid constant flow cylinder is further provided with a liquid level sensor; the first conveying pipeline communicates with the tin liquid storage cylinder and the tin liquid reflux cylinder, and a conveying pump is installed on the first conveying pipeline; the reflux pipeline communicates with the tin liquid reflux hole and the tin liquid storage cylinder; one end of the second conveying pipeline communicates with the tin liquid outflow hole, a pipe mouth used for injecting tin liquid into the cooling mold is formed in the other end of the second conveying pipeline, and an adjusting valve is installed at the other end of the second conveying pipeline; a cavity is formed in the anti-oxidation part, an input hole is formed in the outer side surface, and an output hole used for surrounding the pipe mouth is formed in the bottom surface; a water-cooled inner cavity is formed in the cooling mold, a water inlet is formed in the bottom endsurface, a water outlet is formed in the top end surface, and a cooling circular groove is formed in the edge position of the top end surface; and the shunting circular plate divides the water-cooledinner cavity into an upper cavity body, a lower cavity body and a communicating channel around the edge of the shunting circular plate. According to the casting and forming system, the production quality of the tin bar can be improved, and the production efficiency of the tin bar can be accelerated.

Description

technical field [0001] The invention relates to the technical field of tin material processing, in particular to a casting molding system for tin bars. Background technique [0002] In the production process of tin bars, the tin liquid is often injected into the rotating cooling mold first, and after the tin liquid is cooled and formed into tin bars, the tin bars are taken out from the cooling mold for subsequent cutting and stamping. In the production process of tin bars, there are often the following disadvantages: First, the flow rate of tin liquid injected into the cooling mold is often uncontrollable. If the flow rate is too high, it may cause the tin liquid to overflow. The thickness of the tin bar after cooling and forming is different, which affects the production quality; second, when the tin liquid is injected into the cooling mold, it will splash and roll and ripple, and the tin liquid will mix with the air when it splashes or rolls. Oxygen reacts quickly in the ...

In the production process of tin bars, there are often the following disadvantages: First, the flow rate of tin liquid injected into the cooling mold is often uncontrollable. If the flow rate is too high, it may cause the tin liquid to overflow. The thickness of the tin bar after cooling and forming is different, which affects the production quality; second, when the tin liquid is injected into the cooling mold, it will splash and roll and ripple, and the tin liquid will mix with the air when it splashes or rolls. Oxygen reacts quickly in the tin liquid, which will form a corrugated protective film on the surface of the tin liquid, so that the surface of the tin bar after cooling and forming is relatively rough, which affects the production quality; third, for the existing water-cooled mold, the water inlet and outlet The water outlets are often arranged on the bottom and top surfaces respectively, and most of the cooling water will flow out directly from the water outlet after entering the water inlet, so that most of the cooling water cannot flow to the parts that need water cooling, so that the cooling water cannot be fully utilized cooling effect of
