Hanging mechanism capable of rotation and revolution for mold shell drying

Abstract

The invention relates to a hanging mechanism capable of rotation and revolution for mold shell drying. The hanging mechanism comprises a revolution unit and a plurality of rotation units; the revolution unit comprises a first driving motor, a vertically arranged main shaft and a slewing bearing; the output end of the first driving motor is fixedly connected to the upper end of the main shaft, theslewing bearing is fixed on the bottom wall of a drying box, and the lower end of the main shaft is tightly pressed on the upper surface of the slewing bearing; a plurality of layers of beam frames are vertically fixed on the main shaft, each layer of beam frame is composed of a plurality of cross beams, and one end of each cross beam is correspondingly connected to one rotation unit; and the rotation units comprise disc bodies and rotating shafts, the upper ends of the rotating shafts penetrate through through holes formed in one ends of the cross beams and then are fixedly connected to centers of synchronous belt wheels, and a plurality of synchronous belt wheels are in transmission connection with the same synchronous belt. According to the hanging mechanism, rotation and revolution ofthe multiple batches of to-be-dried mold shells for drying in the drying box can be realized, so that the adverse effect on the drying of the mold shells due to the fact that the temperature in the drying box is not uniform and the wind direction is fixed during blowing can be overcome.

Description

technical field [0001] The invention belongs to the field of casting mold production, and in particular relates to a coupling mechanism capable of autorotation and revolution for mold shell drying. Background technique [0002] Investment casting often uses a ceramic mold shell, which is made by coating a single or multiple layers of material on the outside of the master mold to make the mold shell. The material coated on the outside of the master form is usually a mixture of slurry and sand, which is a granular substance, such as mineral sand, that is sprinkled on top of the slurry. It is also possible not to sprinkle sand when the first coat is applied to the master form. After each layer is completed, it must be dried before the subsequent layer can be applied. It is not until the last layer is completely dry that a mold shell enclosing the master mold is completed. The traditional drying process of mold shell making is to hang to dry naturally at room temperature or ha...
