Abstract

The invention discloses a stepped pouring system and a pouring method for the front and back of multi-row mold shells. The multi-row formwork front and back stepped pouring system includes: a trolley with a front and a back; at least two rows of formwork, and the formwork is at a middle height between the front and the back of the trolley The two sides are low in a stepped arrangement, and a sprue cup is opened on the top of the mold shell; a ladle is located above the mold shell, and the ladle contains molten metal, wherein the sprue cup forms a connecting line. The slope of the ladle should be greater than or equal to the slope of the shape of the ladle; the molten metal in the ladle is poured on the front and / or the back of the trolley respectively and enters the ladle through the sprue cup inside the mold shell. The stepped pouring system on the front and back of the multi-row mold shells provided by the invention has the advantages of simple pouring work, high pouring quality of castings and ideal production efficiency.

Description

technical field [0001] The invention belongs to the field of casting industry, and in particular relates to a stepped pouring system and pouring method for the front and back of multi-row mold shells. Background technique [0002] In the process of investment casting and shell casting, ladles are generally used for pouring. The upper surface of the trolley for placing the mold shells is flat. When the mold shells have the same height and are placed in multiple rows, if you want to pour the middle mold shells , the ladle needs to be lifted to a certain height to cross the formwork on the front and back edges, which makes it more difficult to align the ladle with the formwork. Due to the high pouring water pressure head, the phenomenon of molten metal oxidation, air entrainment and mold shell erosion is prone to occur during the pouring process, resulting in poor casting quality and other problems. Therefore, it is very necessary to provide a stepped pouring system and pourin...
