A flywheel casting mold belongs to the field of flywheel manufacturing. Flywheel casting mold includes: forming inner mold, shell and sprue cup, forming inner mold includes upper coated sand shell, lower coated sand shell and coated sand core, upper coated sand shell, lower coated sand shell and film The sand cores cooperate with each other to form a molding cavity, and the two ends of the coated sand core are in contact with the upper coated sand shell and the lower coated sand shell respectively; The sprue cavity is connected with the upper film-coated sand shell through the opening, and the sprue cavity communicates with the molding cavity. Using the flywheel casting mold can improve the manufacturing precision of the flywheel, simplify the manufacturing process, and improve the quality of the flywheel.
Description
technical field [0001] The invention belongs to the field of flywheel manufacturing, and in particular relates to a flywheel casting mold. Background technique [0002] Existing flywheels are made by casting. However, when the structure of the flywheel is complex, especially the flywheel with a complex inner cavity, the existing molds are difficult to meet the demand, and the mold needs to be replaced frequently, which makes the production more difficult. , the workpiece structure of the blank is poor, and it is difficult to meet the design requirements. Contents of the invention [0003] The purpose of the present invention is to provide a flywheel casting mold, which can reduce the manufacturing difficulty of the flywheel, shorten the processing time, and can also improve the qualified rate of the flywheel. [0004] The present invention is achieved like this: [0005] A flywheel casting mold includes: a molding inner mold, a shell and a sprue cup, the molding inner mo...
