Shell core rapid drying and forming process and device

Abstract

The invention discloses a shell core rapid drying and forming process and device. The device comprises a drying box, wherein the drying box is installed on a rack, and a feeding opening is formed in the side face of the drying box; the sliding rail is mounted on the rack and extends into the drying box from the feeding hole; the sliding plate is arranged on the sliding rail in a sliding manner, is provided with a plurality of ventilation holes in the bottom and is used for bearing the shell core; the turntable is mounted on the top wall of the drying box; the drying assembly is mounted on the turntable and is used for drying the shell core on the sliding plate; the driving assembly is arranged at the top of the drying box and used for driving the turntable to rotate; the air blowing assembly is arranged at the bottom of the drying box and blows hot air to the shell cores on the sliding plate. When the shell core drying device is used, a shell core can be quickly and uniformly dried, so that the drying effect of the shell core can be improved, and the product quality is improved.

Description

technical field [0001] The invention relates to the field of shell core processing, in particular to a shell core rapid drying molding process and device. Background technique [0002] The shell core is commonly known as the mud core. It is used to form the internal cavity of the casting during casting. It is often prepared with sand and binder in a certain proportion. The prepared core generally needs to go through multiple processes, including The process of drying the core. [0003] At present, when drying the core, the core is generally placed directly on the predetermined position of the carrier plate of the drying equipment, dried for a predetermined time, and then the core is taken out to form the desired shell. However, the current drying process has uneven drying, especially for some shell cores with large bottom surface area, the drying effect is poor, which needs further improvement. SUMMARY OF THE INVENTION [0004] The purpose of the present application is t...
