Formwork drying box with autorotation and revolution functions

Abstract

The invention relates to a formwork drying box with autorotation and revolution functions. The formwork drying box comprises a box body, a drying mechanism, a revolution mechanism and an autorotationmechanism, the drying mechanism, the revolution mechanism and the autorotation mechanism are positioned in the box body, the autorotation mechanism comprises multiple autorotation units, the revolution mechanism comprises a first driving motor, a spindle and rotating support, a plurality of beam frames are vertically fixed on the spindle, each beam frame is composed of multiple cross beams, one end of each cross beam is correspondingly connected with an autorotation unit, each autorotation unit comprises a disc, a rotating shaft and multiple horizontal connecting rods, the upper end of each rotating shaft is fixedly connected with the center of a synchronous belt wheel after penetrating a through hole formed in one end of the cross beam, and multiple synchronous belt wheels are in transmission connection with a synchronous belt; the drying mechanism comprises multiple drying units fixed on the inner wall of the box or / and on the revolution mechanism. The formwork drying box has the advantages that the drying box can realize autorotation and revolution of multiple to-be-dried formworks during drying in the drying box in one time, and unfavorable impact of nonuniform temperature in the drying box and fixed wind direction during air blowing on formwork drying can be effectively eliminated.

Description

technical field [0001] The invention belongs to the field of casting mold production, and in particular relates to a mold shell drying box with functions of self-rotation and revolution. 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 formwork production is to hang to dry naturally at room temperature or hang to dry...
