Abstract

The invention provides a pass-type microwave drying system for a sand mould. The pass-type microwave drying system for the sand mould comprises a roller way device, a microwave drying room and a humidity elimination blowing-in device. With humidity control as priority and temperature control as aiding, measuring temperature deviation of the sand mould is reduced, and a mode of top air drafting and bottom blowing-in is adopted so that the fact that air and water vapor in the microwave room circulate smoothly is ensured, quick, efficient and high-class drying of the sand mould is achieved; and multiple patterns such as local operation and remote operation are possessed, integration with other equipment or system is convenient and line production is achieved.

Description

technical field [0001] The invention belongs to the field of sand mold drying, in particular to a sand mold pass-through microwave drying system Background technique [0002] Sand molds commonly used in the foundry industry mainly include 3D printing sand molds, core shooter sand molds and ordinary sand molds. These sand molds generally need to go through the process of coating and drying before core assembly. Water-based coatings and alcohol-based coatings are mostly used for application. After water-based coatings are applied, the sand mold must be dried. The traditional method is to use electric or natural gas surface drying kilns. This drying method consumes a lot of energy, the drying quality cannot be precisely controlled, and the sand mold and the sand box are both high temperature after drying, and there is a greater risk of scalding; at the same time, this method cannot be completely dried for large sand molds. Poor uniformity. [0003] At present, microwaves are ...
