The invention discloses a casting mold preheating device. The preheating device comprises a lower conveying belt, lower conveying wheels, an upper conveying belt, upper conveying wheels, casting molds, electrical bars and fixing columns; the two lower conveying wheels are oppositely arranged; the lower conveying belt winds around the two lower conveying wheels to form an annular shape; the multiple casting molds are arranged on the lower conveying belt; the lower conveying wheels drive the lower conveying belt to clockwise rotate; the two upper conveying wheels are oppositely arranged; the upper conveying belt winds around the two upper conveying wheels to form an annular shape; the two ends of each electrical bar are each connected with one fixing column; the fixing columns at the two ends of the electrical bars are connected with the two sides of the upper conveying belt; the upper conveying belt is located over the lower conveying belt; the upper conveying wheels drive the upper conveying belt to rotate anticlockwise; the electrical bars located below the upper conveying belt are inserted in the casting molds located above the lower conveying belt. According to the device, heating temperature is uniform, and the casting molds can be prevented from being corroded.
Description
technical field [0001] The invention relates to the field of casting, in particular to a casting mold preheating device. Background technique [0002] In the casting process, due to technological requirements, it is necessary to preheat the casting mold before casting to make the casting mold reach a certain temperature. At present, manual hand-held natural gas spray guns are mainly used, and the flames generated by natural gas combustion are used to bake the casting molds. Due to the manual operation, the temperature of the casting mold after heating usually has a large difference from the preset temperature, which cannot meet the process requirements. In addition, the combustion of natural gas produces a large number of different kinds of chemical substances. These chemical substances are easy to cause corrosion to the mold as they attach to the casting mold, thereby affecting the service life of the casting mold. Contents of the invention [0003] The object of the pr...
