Automatic pouring device with adjustable flow speed for sand casting

Abstract

The invention relates to the related field of casting, and discloses an automatic pouring device with an adjustable flow speed for sand casting. The automatic pouring device comprises a main box body,a pouring cavity with a rightward opening is formed in the main box body, a movable nut cavity is formed in the lower side of the pouring cavity, and a movable plate through cavity is formed betweenthe upper end wall of the movable nut cavity and the lower end wall of the pouring cavity in a communicating manner. A lead screw gear cavity is formed in the left side of the movable nut cavity. Molten iron uniformly flows into a pouring opening of a sand mold box under the action of centrifugal force, automatic pouring is achieved, the workload of operators is reduced, the pouring efficiency isimproved, meanwhile, pouring is conducted in a mechanical mode, the safety during pouring can be improved, and the health of the operators is protected; and in addition, the pouring speed can be freely controlled through a molten iron flow speed adjusting mechanism, the requirement for different pouring speeds in different pouring stages is met, meanwhile, the pouring requirements of different sand mold boxes can be met, and the practicability of the device is improved.

Description

technical field [0001] The invention relates to the related field of casting, in particular to an automatic pouring device with adjustable flow rate for sand casting. Background technique [0002] In sand casting, molten iron needs to be poured into the sand mold box. The existing pouring method is generally to manually turn over the molten iron bucket and pour the molten iron into the pouring port. The manual pouring method is time-consuming and laborious, which reduces the pouring efficiency, and it is easy to cause safety accidents due to the lack of protective facilities. , In addition, the flow rate of molten iron is not easy to control in the way of manual pouring, and the flow rates required by different pouring stages and different types of castings are not the same, thus reducing the pouring quality. Contents of the invention [0003] The object of the present invention is to provide an automatic pouring device with adjustable flow rate for sand casting, which can...
