Description

Technical Field

[0001] The utility model relates to the technical field of deburring devices, in particular to a deburring device for holes of investment casting parts. Background Technique

[0002] Investment casting, also known as lost-wax casting, includes processes such as wax pressing, wax trimming, tree assembling, slurry dipping, wax melting, pouring molten metal, and post-treatment. Lost-wax casting is to make a wax mold of the part to be cast with wax, and then coat the wax mold with slurry, which is the clay mold. After the clay mold is dried, it is baked into a ceramic mold. Once baked, the wax mold completely melts and runs off, leaving only the ceramic mold. Generally, a pouring gate is left when making the clay mold, and then molten metal is poured into the pouring gate. After cooling, the required investment casting part is made. After some investment casting parts with through holes are cast, there are certain burrs in the through holes. The existence of burrs will have an adverse impact on many aspects such as the machining accuracy, assembly accuracy, service performance, and appearance quality of the parts. Removing burrs has always been an important process in machining.

[0003] To solve the above technical problems, a Chinese patent with the publication number CN210817776U in the prior art discloses a deburring device for holes of investment casting parts, including a workbench, a tooling table placed on the workbench and used for fixing the investment casting parts, a deburring rod slidably passing through the through hole of the investment casting part, and a driving component for driving the deburring rod to slide.
