Manganese steel casting machining demolding equipment and technology

Abstract

The invention relates to the technical field of manganese steel casting demolding technologies, in particular to manganese steel casting machining demolding equipment and technology. The equipment comprises a casting table, a lower mold box is arranged at the upper end of the casting table, an upper mold box is arranged at the upper end of the lower mold box, the lower mold box and the upper mold box are filled with bonded molding sand, and a mold cavity is formed in an inner cavity between the vertically-filled molding sand. The equipment and the technology have the beneficial effects that the strength of molding sand is greatly enhanced through arrangement of a tension-bearing frame and a torsion-resistant frame, parting surfaces are separated through resetting of springs, and the tensile resistance of the molding sand at the upper end is enhanced through a pressure-bearing plate, so that the upper end of a workpiece is smoothly separated and demolded in the upper mold box through tensile force; through arrangement of a thin sand layer and a disc-shaped conical groove, the cast workpiece is provided with a conical groove base, so that the thin sand layer is broken through rotation of a rotary disc, and the workpiece is driven to rotate; the torsion resistance of the molding sand is enhanced by the aid of a T-shaped plate, so that rising demolding of the workpiece in the rotating process is achieved, the adhesion amount of the molding sand on the outer wall of the demolded workpiece is small, the demolding efficiency is high, and the demolding speed is high.

Description

technical field [0001] The invention relates to the technical field of manganese steel casting demoulding technology, in particular to a manganese steel casting demoulding equipment and technology. Background technique [0002] In the casting process of manganese steel, there are three stages of molding sand cavity making, casting cooling and demoulding. In the prior art, a mold release agent is usually filled in the mold cavity to achieve smooth demoulding. [0003] However, in the actual use process, due to the extremely high temperature of the molten metal during manganese steel casting, the effect of the release agent is poor, and a large amount of molding sand adheres to the outer wall of the workpiece after demoulding, requiring secondary cleaning. The middle is divided into sand box separation and workpiece demoulding. When the sand box is separated, the molding sand in the upper sand box adheres to the workpiece due to the pulling force of the upper and lower separat...

Problems solved by technology

[0003] However, in the actual use process, due to the extremely high temperature of the molten metal during manganese steel casting, the effect of the release agent is poor, and a large amount of molding sand adheres to the outer wall of the workpiece after demoulding, requiring secondary cleaning. The middle is divided into sand box separation and workpiece demoulding. When the sand box is separated, the molding sand in the upper sand box adheres to the workpiece due to the pulling force of the upper and lower separation. During the demoulding process of the workpiece, due to the gravity of the workpiece and the adhesion of the metal during casting The force makes the workpiece tightly adsorbed in the molding sand, making demoulding difficult. After violent demoulding, the adhesion of the molding sand also requires secondary treatment, which greatly affects the efficiency of casting and the utilization rate of molding sand.

[0004] To this end, a manganese steel casting processing demoulding equipment and process are provided to solve the demoulding problem of manganese steel workpiece casting
