Technical Field

The invention relates to the technical field of casting production, in particular to a vibrating table for modeling a nodular cast iron casting.

Background

In the production process of large ductile cast iron castings, the sand box for molding is basically formed by welding steel plates due to the number of castings, the manufacturing cost and the like. Because the large casting is 3-4 meters high, the weight is twenty-three tons, the small casting is also seven-eight tons, and the pressure of a pouring system is added, the resin sand casting mold in the sand box can bear more than 4 meters of static pressure of molten iron, and the scouring force when the molten iron passes through the pouring system, if the rigidity and the strength of the resin sand casting mold can not bear the continuous scouring of the molten iron to cause the casting to be peeled off and enter the molten iron or can not bear the static pressure of the molten iron and the graphite expands in the solidification process of the nodular cast iron, the casting can generate casting defects such as shrinkage cavity, shrinkage porosity and the like, and the molten iron is excessively consumed due to the expansion of the casting mold.

At present, when large ductile cast iron castings are produced in the casting industry, resin sand casting molds are basically vibrated and compacted in modes of manual knocking, treading and the like, the labor intensity is high, the effect is not ideal, vibration motors are adopted to vibrate and compact, the noise during vibration is high, the vibration amplitude is too large, the molds and sand boxes are damaged, and the vibration motors are easy to burn out.

Therefore, in view of the above situation, there is an urgent need to develop a vibrating table for molding ductile cast iron castings to overcome the disadvantages in the current practical application.
