Description

Technical Field

[0001] The utility model relates to the technical field of sand core processing equipment, in particular to an automatic dipping device for sand cores. Background Art

[0002] Sand core is a hollow core made of sand or other materials. It is embedded in the mold during the casting process and is used to form parts with complex shapes such as inner cavity, hollow, thin wall, etc. Sand cores are mainly divided into hot cores and cold cores. Hot cores need to be dipped before use. The purpose of dip coating is to obtain a qualified blank appearance and prevent sand from sticking to the product.

[0003] The patent (CN216176465U) discloses a sand core dipping device for thermocouple protection tubes, which relates to the field of dipping devices. The utility model includes a main body mechanism, including a working platform, a dipping mechanism, including a dipping box arranged on one side of the working platform, and a cleaning mechanism, including a dust removal component arranged inside the dipping box and a recovery component arranged on one side of the dipping box. The dust removal component is used to remove impurities above the dipping coating liquid, and the recovery component is used to recover the contaminated dipping coating liquid. The dust removal component includes a scraper arranged on one side of the inside of the dipping box, and a reset spring is installed on one side of the scraper. A through hole is arranged on one side of the dipping box, and the reset spring is connected to the through hole. The utility model is a sand core dipping device for thermocouple protection tubes. The sand core is placed in a dipping tray, and the cylinder expands the telescopic rod, which will allow the dipping tray to enter the dipping liquid to dip the sand core. After the dipping is completed, the telescopic rod is retracted by the cylinder, and the dipping tray is pulled out of the dipping liquid with the cooperation of the suspension rope to facilitate the recovery of the sand core.

[0004] In the sand core dipping device in the above patent document, the dipping liquid inside the dipping box is in a relatively static state during the dipping treatment, and the contact between the dipping liquid and the sand core is just a simple immersion contact, which leads to poor uniformity of the dipping treatment on the sand core surface and poor dipping effect on the sand core surface.
