Description

Technical Field

[0001] The utility model relates to the technical field of casting pouring, in particular to a roller casting pouring guide device. Background Art

[0002] A casting is a metal shaped object obtained by various casting methods, that is, the smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods, and an object with a certain shape, size and performance is obtained after cooling. The drum casting is a drum-shaped casting. The drum casting is a large thin-walled cylindrical casting. During pouring, the concentricity of the inner hole and the outer circle is required, and the inner and outer surfaces are increased. The casting is not allowed to have defects such as shrinkage cavities, shrinkage, slag inclusions, pores, and sand holes. When pouring the liquid metal, a guide device is required to control the smooth addition of the liquid metal to avoid diffusion and splashing of the liquid metal.

[0003] For example, application number: CN202020287999.3 involves a pouring device for the production of iron castings with a guiding mechanism, including a crane and a guide rail, a column is fixedly provided at the bottom end of the guide rail, the crane is arranged at the top end of the guide rail, a support frame is slidably provided on the surface of the guide rail, the support frame includes a frame, a support rod and a connecting block, a slider is welded and fixed on one side of the connecting block, the slider and the guide rail are arranged to be slidably connected, a plurality of first threaded holes are provided on the two side surfaces of the frame, and the support rod is fixedly connected to the first threaded holes via studs. The utility model drives the liquid storage cylinder to move slightly toward one side of the support frame through the crane operation, so that the bottom end of the liquid storage cylinder contacts the surface of the frame, and the top end is inclined. The staff rotates the adjusting disk, and the first gear disk is driven to rotate through the second gear disk, so that the inclination angle of the liquid storage cylinder can be changed, which is convenient for the outflow of liquid metal in the cylinder. The whole process is easy to operate and efficient.

[0004] Based on the above and the common roller casting guide devices on the market, in the process of adding liquid metal, if the ladle is not controlled accurately, it is easy to contact the guide device, and gravity is applied to the guide device, which can easily cause the guide device to tilt or shift, affecting its use. In addition, when the liquid metal initially enters the guide device, the liquid cannot be circulated and injected at one time, and will temporarily remain in the guide device. However, the liquid metal initially added will surge up and easily splash out, posing a safety hazard. Utility Model Content
