Problems solved by technology

Otherwise, during the pouring process, the temperature of the liquid metal will drop and the flow rate will slow down due to the long pouring method, and the liquid metal will not be able to enter the cavity in a timely and smooth manner, resulting in failure to form the casting or casting waste
Due to the large number of sand mold cavities and long runners in series, the problem of large amount of molten iron and long pouring time arises. Therefore, how to speed up the flow rate of molten iron in the runners has become the key technical problem to be considered and solved in this plan.

Abstract

The invention provides a sprue optimization structure and method for accelerating the flow rate of molten iron. The tundish system is docked; the tundish system includes the tundish, the upper closed structure connected with the side of the tundish, the lower closed structure connected with the bottom of the tundish, and the tundish is also connected with the protective gas device and the rotary drive mechanism; the lower closed structure The bottom is docked with the sprue cup, the side of the lower closed structure is connected with the vacuum pump system, the protective gas device, and the lifting adjustment mechanism, and the upper sealing structure, the lifting adjustment mechanism and the rotation driving mechanism are all arranged on the bracket. The sprue optimization structure and method for accelerating the flow rate of molten iron provided by the present invention accelerate the flow of molten iron in the sprue, reduce the pouring time, and avoid the temperature drop of the molten iron. The sprue optimization structure also has multifunctional technical effects.

Description

technical field [0001] The invention belongs to the technical field of casting molding, and in particular relates to a sprue optimization structure and method for accelerating the flow rate of molten iron. Background technique [0002] In daily production, steel, iron and most non-ferrous metal alloy castings can be obtained by sand casting. In the prior art, castings are all cast by sand molds. In order to increase the quantity of castings formed in one pour, pouring is performed in series. Casting in series can reduce the number of pours, increase the number of castings formed by one pour, improve efficiency, improve the utilization of molten iron, reduce casting costs, and reduce labor costs. [0003] In the prior art, when pouring is performed by connecting sand molds in series, liquid metal cannot enter the mold cavity within a specified time due to the large number of sand molds and long runners. Therefore, when pouring in series, it is necessary to increase the flo...
