Abstract

The invention discloses a full-automatic sand core dip-coating system and a dip-coating method thereof. The full-automatic sand core dip-coating system comprises a feeding unit, a dip-coating unit, a clamping unit, a cleaning unit and a control system electrically connected with all the units. The feeding unit is used for providing a sand core blank; the clamping unit is used for clamping and transferring a sand core, and the dip-coating unit is used for dip-coating the sand core, and comprises a dip-coating module and a circulating module; and a cleaning device is used for cleaning a fixture. According to the dip-coating system, the integrated automatic process of sand core feeding, purging, dip-coating, conveying and fixture cleaning is achieved, not only is the labor cost greatly saved, but also the production efficiency and the casting quality are improved.

Description

technical field [0001] The invention relates to the technical field of sand core dip coating, in particular to an automatic sand core dip coating system and a dip coating method thereof. Background technique [0002] The supporting hydraulic valves and hydraulic pumps in the construction machinery industry generally adopt the sand core casting process in the production and casting process. Generally used sand cores (inner cores) need to be dip-coated and dried before use. In the dip coating process of the sand core, the traditional method is to manually take the sand core and dip it into the paint, then manually shake off the excess paint on the surface of the sand core, and then put it on the roller tray in the front section of the drying furnace for surface coating. drying. This production process adopts the methods of manual dip coating, manual spin coating, and manual handling and discharging. The labor intensity of personnel is high and boring, and the production effic...
