Description

Technical Field

[0001] The utility model belongs to the technical field of casting equipment supporting, and particularly relates to a mechanism for realizing the unhooking and hanging of a ladle by changing the gear meshing angle of a flask molding line. Background Technique

[0002] With the requirements of modern production automation, the requirements for all aspects of casting equipment are getting higher and higher. Therefore, how to achieve a fast and accurate ladle changing method and how to achieve the diversification of castings are the problems that need to be solved now. Summary of the Invention

[0003] In order to solve the above technical problems, the utility model provides a mechanism for realizing the unhooking and hanging of a ladle by changing the gear meshing angle, which can achieve a fast and accurate ladle changing method and this structure can withstand ladles of different specifications, so as to realize the diversification of castings during the pouring process.

[0004] A mechanism for realizing the unhooking and hanging of a ladle by changing the gear meshing angle includes a passive sprocket, a driving gear shaft, a gear, a sector gear, a toggle plate frame, a hanging wall and a pin shaft.

[0018] The working principle of the present utility model is as follows:

[0019] In a flask molding line, the ladle is filled with molten iron. At this time, the gear meshing angle in the flask molding line changes from -2 degrees to 0 degrees. The hanging shaft of the ladle is hung on one end with a groove of the hanging wall to realize hanging the ladle. When pouring the molten iron, the gear meshing angle continues to change to increase the tilting angle of the ladle. When detaching the ladle, changing the gear meshing angle in the flask molding line from 0 degrees to -2 degrees can realize the ladle detaching action.

[0020] The present utility model is a high-precision and fast ladle hanging and detaching mechanism. Since this mechanism is for pouring molten iron around the pouring nozzle, the strength requirement for the hanging shaft is not very high, and it can realize customers pouring models of different sizes; this mechanism has a long service life, saves costs, and is a stable and reliable mechanism for realizing the hanging and detaching of a ladle by changing the gear meshing angle in a flask molding line.
