Jacking type sand core microwave drying device

Abstract

The invention relates to a jacking type sand core microwave drying device. The drying device mainly comprises a microwave drying cavity, a jacking assembly and a sand core tray, wherein the jacking assembly comprises two supporting stand columns and a jacking sealing bracket arranged between the two supporting stand columns; a vertical linear rail is arranged on each supporting stand column; the jacking sealing bracket is jacked and descended on the supporting stand columns through the vertical linear rails; an inner roller way is arranged on the jacking sealing bracket, and is used for beingmatched with a outer roller way to carry and transport the sand core tray; the microwave drying cavity is located above the supporting stand columns; the bottom of the microwave drying cavity is provided with a feeding opening; when the jacking sealing bracket ascends, the jacking sealing bracket is in sealing connection with the feeding opening. Through matching and sealing of the jacking sealingbracket and the upper microwave drying cavity, microwave leakage prevention is carried out, the problem of microwave leakage is effectively solved, and 3D printing sand core flow coating and automatic drying after dip coating are efficiently realized.

Description

technical field [0001] The invention belongs to the field of microwave drying equipment and is used for automatic drying equipment for casting 3D printing sand cores, in particular to a microwave drying equipment for jacking sand cores, which is suitable for 3D printing intelligent automatic casting sand cores after flow coating and dip coating Automatic real-time drying. Background technique [0002] Traditional foundry sand cores are dried by equipment such as natural gas drying kilns. Not only is the drying efficiency low, the surface strength of the sand cores after drying is low, and various dust impurities are produced during the drying process, which seriously pollutes the factory environment. There is a certain damage to the health of long-term workers. At present, with the application of foundry 3D printing technology, microwave drying has begun to be applied to the drying of foundry sand cores. Compared with traditional natural gas furnaces, existing microwave dry...

Problems solved by technology

However, for microwave drying equipment, microwave leakage is an important factor restricting its wide application, especially the microwave leakage at the door of the microwave oven. There is a big difference, so there is still room for improvement in the microwave leakage prevention measures
