The invention discloses an exhaust pipe water-cooled sand core mould which comprises an upper mould and a lower mould. The upper mould is provided with a boss which is provided with an upper mould core, the lower mould is provided with a groove which is internally provided with a lower mould core, and the upper mould core and the lower mould core are in correspondence. The upper mould core comprises an upper mould body, a first upper connection portion and a second upper connection portion, and the first upper connection portion and the second upper connection portion are arranged on the outerside of the upper mould body. The lower mould core comprises a lower mould body, a first lower connection portion and a second lower connection portion, and the first lower connection portion and thesecond lower connection portion are arranged at two ends of the lower mould body respectively. By the exhaust pipe water-cooled sand core mould, the technical problem of difficulty in processing dueto poor integral casting precision of sand core moulds in the prior art is solved.
Description
technical field [0001] The invention relates to the technical field of exhaust pipe molds, in particular to a water-cooled sand core mold for exhaust pipes. Background technique [0002] Casting mold means that in order to obtain the structural shape of the part, other easy-to-form materials are used to make the structural shape of the part in advance, and then the mold is placed in the sand mold, so a cavity with the same structural size as the part is formed in the sand mold. Then pour a fluid liquid into the cavity, and after the liquid cools and solidifies, it can form a part exactly the same as the shape and structure of the mold. Sand casting is a kind of casting process. The mold used in sand casting is generally composed of outer sand mold and core. Because the molding materials used in sand casting are cheap and easy to obtain, the casting mold is easy to manufacture, and it can adapt to the single-piece production, batch production and mass production of castings....
