[0002] The turbine sand core is a sand core used on automotive turbocharger castings. The production of the turbine sand core adopts the hot core box coated sand process, which is a high-end, complex and high-precision process. During the core making process, the entire turbine sand core is first cast in a shell mold and shell core manner, that is, the outer shell and inner core of the sand mold are sanded by a core making machine. After casting, the turbine sand core is polished by a polishing station. Due to the complexity and particularity of the sand core, there are often defects on the surface of the sand core. In order to increase the surface quality of the turbine sand core, all of them need to be dipped in water-based coating after polishing, that is, a water-based composite material is dipped on the surface to make it smoother.

[0003] In the prior art, the turbine sand core needs to be left to stand after being dipped in the coating slurry pool and taken out, so that the slurry can flow to the bottom of the sand core. After standing, the slurry gathers at the bottom of the sand core. The slurry at the bottom of the sand core is manually wiped, which is labor-intensive and time-consuming and not easy to automate.

[0004] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content
