Description

Technical Field

[0001] This utility model relates to the field of lost-wax casting technology, and in particular to an auxiliary device for slurry application and sand pouring of cage-type blade wax molds. Background Technology

[0002] Lost-wax casting, also known as investment casting, is a precision casting process with little or no machining. It is an excellent technology in the precision casting industry with a wide range of applications. It is suitable not only for precision casting of various types and alloys, but also for producing castings with higher dimensional accuracy and surface quality than other precision casting methods. Even complex, high-temperature resistant, and difficult-to-machine castings that are difficult to produce using other precision casting methods can be obtained using investment casting.

[0003] In lost-wax casting, after the wax model is poured and shaped, it is usually necessary to bond the wax model to a pouring cup. Then, an operating rod is connected to the pouring cup. The pouring cup and the wax model are moved by the operating rod, and slurry is adhered to the surfaces (inner and outer surfaces) of the pouring cup and the wax model. Sand is then poured onto the surface of the slurry. After drying, slurry is adhered and sand is poured again. This process is repeated several times to form a hard shell on the outside of the wax model.

[0004] However, in the sand pouring process, in addition to the need for operators to pour sand and shake the screen to spread sand evenly downwards, operators also need to hold the operating rod to rotate the wax model so that all corners and surfaces of the wax model can be evenly covered. This consumes a lot of human resources and affects production efficiency. Utility Model Content
