Description

Technical Field

[0001] The utility model relates to the technical field of investment casting, in particular to an investment casting pouring bracket structure. Background Art

[0002] Investment casting includes the processes of wax pressing, wax repairing, tree assembly, slurry dipping, wax melting, pouring molten metal and post-processing. Its biggest advantage is that it can reduce machining work and can cast complex castings of various alloys. In investment casting, the solution tank needs to be poured from the pouring port into the mold to achieve casting molding. In the casting process, a pouring bracket is needed to place the solution tank and the mold to realize the pouring of the solution.

[0003] A Chinese patent discloses a pouring support for investment casting (authorization announcement number CN218134906U). This patented technology is suitable for pouring molds of different sizes. After the mold is placed on the middle support, the mold naturally droops and the bottom contacts the oscillation plate. After the molten metal is poured into the container on the top, during the pouring process, the oscillation plate slides back and forth through the transmission between the wire wheels and drives the mold to shake, so that the bubbles generated by the molten metal flowing into the mold can escape during the shaking process, thereby reducing the bubbles present in the casting.

[0004] However, there are still some shortcomings in this patent. Although this patent can shake the mold to reduce bubbles, it needs to be driven by a wire wheel when shaking the mold. This method has a complex structure and requires coordination between structures to achieve transmission, which in turn affects the shaking of the mold and causes the quality of the product to decline. Therefore, those skilled in the art provide a casting bracket structure for investment casting to solve the problems raised in the above background technology. Utility Model Content
