Background

The investment casting is also called lost wax casting, and comprises the procedures of wax pressing, wax trimming, tree forming, slurry dipping, wax melting, molten metal casting, post-treatment and the like. Lost wax casting is a process in which a wax pattern for a part to be cast is made of wax and then coated with slurry, that is, a clay pattern. And after the mud mold is dried, putting the mud mold into hot water to melt the internal wax mold. Taking out the mud mould melted with the wax mould and roasting to form the ceramic mould. Once calcined. Generally, a pouring gate is left when a mud mould is manufactured, then molten metal is poured into the mud mould from the pouring gate, and after the mud mould is cooled, required parts are manufactured. Wherein, the internal environment in wax melting pond directly influences the sample qualification rate of later stage casting work piece, and a good wax melting pond can improve the quality of casting work piece, and equally, a poor wax melting pond can directly destroy the casting work piece.

The existing wax melting tank has the advantages that in the using process, the scraps of partial cast workpieces are left inside the wax melting tank, the scraps can be directly deposited at the bottom of the tank due to the influence of the self weight, the quality of wax-like liquid inside the wax melting tank can be influenced through long-term accumulation, and due to the fact that no good fishing measures are provided, the cast workpieces which are waxed in the later stage can carry away a large amount of impurities, the calcining temperature after influence is achieved, and the qualified rate of finished workpieces is low. We have therefore developed this and propose an investment casting wax bath.
